• Zhang Tianyuan invited the delegations to visit the Society’s temporary base and travel to a parallel spacetime, then left through the Spacetime Tunnel.
• Officials from the delegations rushed to report the announcement, while meteorologists and United Nations staff remained at the venue and the television station celebrated its record audience.

Zhang Tianyuan’s speech triggered worldwide panic over a coming climate catastrophe, while Becker tried to suppress the news and reassure North America. Jack publicly supported the warning, urged his family to flee south, and learned he and his colleagues could not return home.

• Viewers across the world reacted to Zhang Tianyuan’s speech with alarm, and many began preparing to leave northern regions.
• Becker ordered the agreement tested, restricted the broadcast footage, and went to consult his superior about the spreading panic.
• Jack abandoned his prepared remarks and publicly said the climate warning should be taken seriously, drawing attention and support at the conference.
• Reports and recordings of the speech spread widely, prompting panic and conspiracy theories; Becker then called Zhang Tianyuan and his group charlatans in a national address.
• Jack finally reached Lucy and urged her to take Sam south before October, insisting the catastrophe was real.
• Jack told Lucy he, Jason, and Frank were barred from returning to North America, and asked her to warn their families.

Lucy told Sam that they had to leave Washington for Miami before October, while the Mutual Aid Society prepared visiting delegations to cross into another parallel spacetime. Zhang Tianyuan led the visitors through the Spacetime Tunnel toward No. 4 Spacetime, where the apocalyptic crisis had been resolved.

• Lucy told Sam they had to leave Washington before October because of events in New Delhi, and Sam agreed to go.
• Becker continued controlling information about the climate catastrophe, while many people left Washington and fewer foreign representatives committed to the Mutual Aid Society visit.
• Liu Chunshi brought Jack, Jason, and Frank to join the visiting delegations, who signed their invitations and fingerprints before entering the tunnel.
• Zhang Tianyuan greeted the assembled representatives, reassured them, and led Elder Zhong through the Spacetime Tunnel.
• Jack and the other visitors followed the queue toward the tunnel as Liu Chunshi revealed that they were heading to No. 4 Spacetime, where the apocalyptic crisis had been resolved.

Jack and the other representatives arrived in No. 3 Spacetime and toured Moyulan Base, where they saw the Pangu mecha. Meanwhile, Carl privately asked Zhang Tianyuan for permission to use the Spacetime Tunnel to confront Becker, but he rejected her plan and insisted they continue with the existing approach.

• Jack crossed the tunnel with Liu Chunshi and the other scholars, then opened his eyes to see the enormous Pangu mecha.
• Mako Mori welcomed the representatives to Moyulan Base and explained that the Pangu had helped end the age of monsters and joined Support Team No. 0.
• Zhang Tianyuan left the tour to oversee the scheduled destruction of nuclear bombs aimed at the Precursors' planet.
• Carl asked Zhang Tianyuan for temporary permission to use the Spacetime Tunnel, hinting that she wanted to deal with Becker by force.
• Zhang Tianyuan stopped Carl and warned her not to repeat the idea, telling her to follow the Mutual Aid Society's existing plan instead.

Mako Mori explained the Mutual Aid Society’s nuclear-weapons disposal mission and showed the representatives Pacific Rim Spacetime’s history of fighting the Precursors, convincing them of the Society’s power and the coming disaster. She then led the group through a Spacetime Tunnel to No. 3 Spacetime, the next stop on their tour.

• Mako Mori clarified that the nuclear weapons were being eliminated on the Precursors’ planet and came from two other spacetimes, leaving the representatives alarmed by the Mutual Aid Society’s arsenal.
• Mako Mori showed the representatives records and footage of the Precursors’ monsters and humanity’s battles against them, then took them to see the monsters’ preserved remains.
• The representatives learned about Pacific Rim Spacetime’s technology, industry, and political situation, and many resolved to support the southward migration plan after returning home.
• Mako Mori led the representatives through a newly opened Spacetime Tunnel to No. 3 Spacetime, carrying documents for her own business there.

Wang Lei escorted the spacetime representatives through an underground city and explained that a faction seeking migration to other spacetimes had split between lawful resettlement and invasion. The representatives reached the residential district shaken by a staged leaflet attack and wary of the faction’s interest in their worlds.

• Wang Lei introduced himself as the head of the rescue team and led the representatives away from the tunnel, while Moriko Masami left with documents.
• Wang Lei explained that another group had offered the representatives aid in exchange for signing a cross-spacetime migration and resettlement agreement.
• Wang Lei and Liu Shichun revealed that the group was in Underground City B, about fifteen thousand kilometers below the surface.
• A resident threw a backpack toward the representatives, but Wang Lei shot it and revealed it contained leaflets; Liu Shichun said such incidents were common.
• Wang Lei described the Migration Faction’s goals and explained that some members wanted to seize resources through invasion.

Wang Lei led the representatives from The Day After Tomorrow Spacetime to the surface, where they witnessed a Planetary Engine firing and learned that it was built to propel Earth. The representatives then heard how the United Government formed the Wandering Earth Project to escape the sun’s coming disaster.

• Wang Lei took the representatives to an equipment room, where they put on cold-weather suits and prepared to go outside.
• Wang Lei led the group up a massive elevator, and Liu Chunshi told Jack that the surface temperature was around minus sixty-three degrees.
• The elevator opened onto an icy surface, and the representatives saw a vast steel structure fire a blue pillar of light into the sky.
• Liu Chunshi explained that the structure was a Planetary Engine designed to propel Earth and that its test firing produced 150 trillion tons of thrust.
• Wang Lei identified the structure as the BJ No. 3 Planetary Engine and began explaining how the sun’s impending helium flash led to the Wandering Earth Project.

Wang Lei explained that No. 3 Spacetime had begun the Wandering Earth Project, using planetary engines to move Earth toward Alpha Centauri after biosphere experiments made a self-sustaining spaceship impossible. The representatives left for their next visit after surrendering Migration Faction leaflets, emerging beside an enormous railway yard.

• Wang Lei told Jack and the representatives that failed biosphere experiments led No. 3 Spacetime to abandon building a spaceship and instead use Earth as one.
• Jack and the representatives watched the BJ No. 3 Planetary Engine fire and learned that the plan aimed to reach Alpha Centauri in 2,500 years.
• Wang Lei explained that No. 3 Spacetime had continued the Wandering Earth Project because migration between spacetimes lacked sufficient support and the Mutual Aid Society had only recently made contact.
• The representatives toured No. 3 Spacetime, learned it had developed heavy nuclear fusion, and considered the technology's value to their own worlds.
• Wang Lei required the representatives to hand over Migration Faction leaflets before they departed through a Spacetime Tunnel.
• The representatives emerged beside a long corridor overlooking parallel railway tracks.

Zhang Tianyuan and the branch presidents presented the representatives with a rescue plan for the approaching climate catastrophe and promised help from other spacetimes. As the meeting addressed relocation, shelter, supplies, and energy, Sun Deyi offered a space station to support communications.

• Elder Zhou showed the representatives No. 1 Spacetime’s vast railway network and explained that it was transporting people and supplies through a Spacetime Tunnel to No. 2 Spacetime.
• Elder Zhou learned from Hu Haoran that the representatives’ spacetime had only a little over a month before its climate catastrophe, and he promised the branches would help.
• Zhang Tianyuan introduced the branch presidents, confirmed the representatives accepted the Mutual Aid Society’s existence and the coming disaster, and shared the relocation-and-shelter plan.
• The representatives raised concerns about relocation, shelters, supplies, energy, and communications, especially for small northern countries with limited resources.
• Zhang Tianyuan, Elder Zhou, Tong Wenshi, and Ning Jihua offered relocation guidance, temporary refuge in No. 2 Spacetime, and pooled food and energy for shelters.
• Sun Deyi offered to provide the representatives’ spacetime with a space station for support.

Sun Deyi and Zhang Tianyuan offered the delegates evacuation support and a space station, and the delegates returned home to urge their countries to join the Mutual Aid Society. As countries across three continents announced their membership and coordinated operations disarmed Becker’s overseas forces, Becker blamed a conspiracy and appealed to his superior to save the world.

• Sun Deyi offered to send the Navigator Space Station through the Spacetime Tunnel to provide communications services, and Zhang Tianyuan promised to support countries joining the Mutual Aid Society.
• The delegates signed authorization documents and returned home, where they urged their governments to begin evacuations and join the society.
• Zhong Ruijin told other countries his country was ready to evacuate people, increasing pressure on them to act.
• On September 3, a small Northern Hemisphere country announced it would join the Mutual Aid Society and relocate its people before October.
• Becker learned that countries across Asia, Europe, and North America had announced support for the society, then discovered his forces abroad had been disarmed.
• Becker told his superior that the coordinated operation was a conspiracy and claimed he had to save the world from it.

Zhang Tianyuan and the Mutual Aid Society secured international support and accelerated preparations for the coming climate catastrophe, while Becker struggled to keep his country from joining the southward migration. As the evacuation began across the Northern Hemisphere, news of the disaster spread through North America, leaving Lucy unwilling to wait any longer.

• Zhong Ruijin and the Mutual Aid Society seized Becker’s overseas bases, prompting more countries to join the Mutual Aid Society and announce evacuation plans.
• Zhang Tianyuan and Elder Zhong discussed how Becker’s interest groups resisted evacuation, while Carl prepared to negotiate with Becker again.
• Elder Zhong launched the domestic evacuation plan, and Zhang Tianyuan reviewed plans to move or shelter populations at home and abroad before the catastrophe.
• News of the climate catastrophe spread across North America despite Becker’s efforts to suppress it, and growing panic drove more people to flee south.
• Lucy, still unable to contact her husband, decided she could not wait any longer.

Lucy prepared to take Sam to Miami as the climate crisis deepened and Jack and his colleagues remained unreachable. After Sam vanished, Lucy feared she was under surveillance, while the Mutual Aid Society sent massive reinforcements to quell unrest and support evacuations.

• Lucy told Sam they would leave for Miami the next morning because Jack had warned them to go, and she learned that Frank and Jason were also unreachable.
• Sam called Laura about their school competition, heard her family did not believe the climate danger, and listened to Becker's speech on television before asking a friend if he could stay over.
• Sam slipped out of the house at night, and Lucy discovered the next morning that he was missing; the school and police offered no immediate help.
• A surveillance operative reported that Lucy seemed to have noticed the watchers outside her home.
• Zhang Tianyuan deployed nearly five hundred thousand Mutual Aid Society members to assist with evacuations, calming unrest, while Wang Lei coordinated aid and rescue resources.

Soldiers unloaded communications equipment and supplies at the shelter as exoskeleton-equipped teams helped with the evacuation effort. After returning to The Day After Tomorrow Spacetime, Jack learned from Lucy that their son Sam had mysteriously disappeared, and he suspected the FBI had targeted him.

• Soldiers unloaded heavy communications equipment at the shelter and envied the exoskeletons worn by the unloading team, but the squad leader learned that about fifty people were ahead of him to borrow one.
• The nationwide shelter evacuation continued with aid teams from Wandering Spacetime and the "2012" spacetime branch helping with transport, equipment testing, and cold-weather preparations.
• Liu Chunshi returned to The Day After Tomorrow Spacetime with his meteorological team, and Jack and his companions arranged calls to their families.
• Jack reached Lucy, who had feared he was missing, and told her he had traveled to a parallel spacetime.
• Lucy told Jack that Sam had vanished from home before she planned to leave for Miami and still had not returned.
• Jack suspected the FBI had taken Sam in retaliation for his departure from New Delhi.

Jack apologized to Lucy and sought Tom’s help to find Sam, while reports of New Delhi’s snowfall fueled evacuations and the Mutual Aid Society reviewed its completed relocation efforts. Zhang Tianyuan learned that Carl’s efforts had helped trigger a mass flight from Washington as the disaster drew closer.

• Jack promised Lucy he would bring Sam back, told her to stay at the hospital, and arranged how they would contact each other if separated.
• Jack called Tom, learned that the meteorological bureau was under surveillance, and asked him to help find Sam; Tom agreed to do his best.
• Lucy saw patients and families leaving the Washington hospital after hearing that snow had fallen in New Delhi and October was near.
• At an international climate conference, Liu Chunshi reported New Delhi’s heavy snow and other emerging weather threats while member countries said their evacuations were essentially complete.
• Zhang Tianyuan acknowledged the evacuation work’s shortcomings and received a call from Carl, who reported that people were fleeing despite Becker’s renewed speech.

As extreme weather worsened around the world, Becker ordered California to prepare for Hurricane Nonali and planned to publicly deny a climate catastrophe. Meanwhile, a weather buoy reported a sudden 13-degree drop in ocean temperature near the hurricane, and enormous hailstones killed people in Tokyo, intensifying panic and flight across North America.

• At school, Sam stayed with his friend’s family and enjoyed his freedom while smiling at Laura, unaware that his parents believed the FBI had taken him.
• Becker learned that millions had fled south and that New Delhi’s snowfall was worsening, then warned California to prepare for Hurricane Nonali, whose strength was predicted to be unprecedented.
• Becker told his superior about the worsening situation and then arranged to give an interview exposing what he called the lie of a climate catastrophe.
• At the Hedland Meteorological Observation Center, Professor Rapson and Dennis discussed the predicted global disaster as a buoy near the hurricane registered a sudden 13-degree Celsius drop in seawater temperature.
• In Tokyo, enormous hailstones smashed through the streets and killed rioters, while reporters broadcast the disaster to viewers.
• After the snowfall in New Delhi and lethal hail in Tokyo became widely known, North Americans panicked and fled in greater numbers, spurred on by Carl.

Sam traveled north from Washington as people scrambled to flee south, while global weather warnings intensified. As the North Atlantic rapidly cooled and the climate catastrophe became undeniable, shelters sealed across the country, and a Wandering Spacetime soldier arrived to escort Professor Rapson and his assistants to safety.

• Sam picked up a flyer warning of worsening global climate and traveled to New York with Laura and Brian, who debated whether the crisis was real.
• Houston canceled Parker’s return mission and warned him to monitor the unstable climate and a possible new space station near his orbit.
• Zhang Tianyuan and Elder Zhong ordered shelters across the country to seal and activate their emergency plans as the climate approached a critical turning point.
• Professor Rapson, Dennis, and their assistant confirmed that multiple North Atlantic buoys recorded a rapid, unprecedented drop in seawater temperature.
• A Wandering Spacetime soldier reached the Hedland Meteorological Observation Center and escorted Professor Rapson and his two assistants toward Scotland Shelter No. 97.

Sam noticed the effects of the climate catastrophe while competing in New York, as California was struck by devastating tornadoes and Becker finally ordered a nationwide disaster warning. The chapter ended with Tom learning that Sam was in New York at an academic competition, not in FBI custody.

• Sam competed with Laura and Brian in a sparsely attended academic contest and heard students argue over whether the climate catastrophe was real.
• Jack warned Tom that a dangerous storm system would form off California, but Tom said officials had not acted on the warning.
• A tornado outbreak devastated Los Angeles, and Zack realized the climate warning on the flyers he had distributed was true.
• Becker saw the California destruction, accepted that the Mutual Aid Society's forecasts were credible, and ordered a nationwide meteorological disaster warning.
• Becker privately noted that only ten hours remained before major Northern Hemisphere storm systems formed, while Tom began organizing emergency preparations.
• Tom contacted the FBI and learned that Sam was in New York participating in an academic competition.

Jack learned that Sam was safe in New York and planned to bring him home, while a climate catastrophe began intensifying across the world. As Sam rushed out to buy supplies and astronauts spotted an enormous object beside the International Space Station, the crisis escalated.

• Tom told Jack that Sam had run away to New York with Laura, and Jack reassured Lucy that their son was safe while urging her to leave Washington before the storm arrived.
• Jack asked Liu Chunshi to help him return to New York, and Liu said a future rescue mission might give him and other foreigners a chance to leave.
• Liu learned that a storm had formed over the British Isles with temperatures as low as minus one hundred degrees, then contacted Wang Lei about Jack and the worsening emergency.
• In New York, Sam watched Becker warn of climate disasters, then ran out into heavy rain to buy supplies with Brian and Laura waiting behind.
• Parker and the other astronauts observed a rapidly expanding storm cloud over North America, then noticed a huge object suddenly appear beside the space station.

The Navigator Space Station arrived in the disaster-stricken spacetime and made contact with the International Space Station as it prepared to broadcast worldwide. Zhang Tianyuan announced that the global shelter communications network was online and began sharing meteorological data and search access.

• Wang Lei ordered shelters and independent units to activate their communications equipment, and reports confirmed that shelters around the world remained connected with no emergencies reported.
• Astronaut Parker and his crewmates spotted the Navigator Space Station and received its message explaining that it came from a parallel spacetime.
• Zhang Tianyuan learned that the station had passed its inspection, launched communications satellites, and instructed Liu Peiqiang to begin the worldwide broadcast.
• Sam, Brian, Laura, and J.D. listened to reports of California's devastation while driving through New York traffic, then heard the Navigator Space Station's broadcast interrupt the radio.
• The Navigator Space Station connected every shelter, established a global real-time communications network, and began transmitting meteorological data and search access.

Zhang Tianyuan coordinated stranded vehicles and agreed to consider Becker’s coming request for rescue on the condition that he paid the full costs and compensation. As a worsening storm threatened more disasters, Becker prepared to contact Carl, while Sam and his friends heard the Navigator Space Station’s self-rescue broadcast and noticed a change in a television speech.

• Zhang Tianyuan learned that 894 vehicles were stranded in Europe and ordered their locations and information shared with their destination shelters.
• Zhang Tianyuan told Carl he would accept Becker’s request for help if Becker’s people paid all rescue costs and sufficient compensation to the Mutual Aid Society.
• Becker learned that a major storm and more tornadoes could be coming, then decided to ask Carl for a meeting.
• Sam, Brian, Laura, and J.D. listened to the Navigator Space Station’s self-rescue broadcast and discussed what they knew about the Mutual Aid Society.
