Chapter Summaries

Zhang Tianyuan explained to Tong Wenshi that he could travel between parallel spacetimes and proposed cooperation through the Parallel Spacetime Mutual Aid Society. Tong Wenshi remained unconvinced, but agreed to inspect the command systems in Zhang Tianyuan’s vehicles as corroborating evidence and took a membership application to review.

• Zhang Tianyuan told Tong Wenshi that he and his people came from another parallel spacetime and had arrived to help.
• Tong Wenshi asked for proof before discussing cooperation, and Zhang Tianyuan explained that opening a Spacetime Tunnel was not practical yet.

• Tong Wenshi’s adviser arranged to board the vehicles and examine their systems.
• Zhang Tianyuan produced a Parallel Spacetime Mutual Aid Society Member State Application, which Tong Wenshi accepted to review.

Zhang Tianyuan’s group explored Tong Wenshi’s settlement and learned how badly the apocalypse had disrupted industrial production. After experts confirmed that their command systems came from different military systems, Tong Wenshi asked why Zhang Tianyuan wanted to help, and Zhang revealed that the aid was meant to secure help for Bai Xu’s world in its own future crisis.

• Zhang Tianyuan learned that more than forty thousand people lived in the settlement, but only a little over ten thousand had arrived after hearing the apocalypse broadcasts.
• Zhang Tianyuan, Instructor Yin, and Wu Yisi discussed how the high death toll and lack of industry kept survivors from reclaiming cities from the Darkseekers.
• Programming experts compared the command vehicles and found that their similar systems had distinct underlying code and design requirements.
• Tong Wenshi agreed to continue talks with Zhang Tianyuan after learning that his group’s command system belonged to an independent military.
• Tong Wenshi asked why Zhang Tianyuan wanted to help, and Zhang explained that Bai Xu’s world hoped the settlement would someday help it survive its own apocalypse.

Tong Wenshi weighed Zhang Tianyuan’s offer to help his settlement and signed an application for membership in the Mutual Aid Society. Zhang asked him to establish a local branch and recruit survivors, while promising cooperation and support against the KV Virus and the coming apocalypse.

• Bai Xu explained that his spacetime faced a predicted global catastrophe in 2012 and that its citizens would need refuge in Tong Wenshi’s world.

• Tong Wenshi consulted the other leaders, then returned at night to ask Zhang why he was helping their settlement.
• Zhang gave Tong a new membership application, which Tong signed, and asked him to create a Mutual Aid Society branch and recruit survivors using fifty thousand applications.

Tong Wenshi sought Zhang Tianyuan’s protection against the possibility that Bai Xu’s powerful timeline would annex his country, and agreed to bring survivors into the Mutual Aid Society. The next morning, Zhang Tianyuan told Ding Jingye that he could resolve the pregnant women’s childbirth crisis that day.

• Tong Wenshi signed an application to join the Mutual Aid Society and arranged to travel with the pregnant women to another timeline the next day.

• Staff showed footage of Legend World, and Qian Xiu told his friend he would go.

Qian Xiu and nearly ten thousand others prepared to travel to Legend World, accepting the risks of the parallel spacetime. Zhang Tianyuan led the massive convoy through the Spacetime Tunnel, and a satellite passing afterward photographed only the empty grounds.

• Qian Xiu and his friend decided to join the mission to Legend World, and fewer than ten people withdrew before the count reached 9,956.
• After intensive training, Zhang Tianyuan and the team assembled tanks, helicopters, and support vehicles for the return journey.
• Zhang Tianyuan organized the force into seven departments and ordered them to enter the Spacetime Tunnel before a satellite passed overhead.
• At 8:35, Zhang Tianyuan opened the tunnel and the entire convoy vanished from the grounds.
• Ten minutes later, a satellite passed overhead and captured an empty grounds covered in tire tracks.

The “2012” leadership covertly prepared a nationwide evacuation, diverting resources toward railways, ships, and training workers. On the grasslands, Bai Xu and the settlement’s leaders worried as Zhang Tianyuan’s group stayed away, until a convoy appeared and Bai Xu realized they had returned.

• Tong Wenshi permitted Xu Tianji’s team to consult and send the records to No. 1 Spacetime, and Zhang Tianyuan assigned the team to sort, disinfect, and pack them.
• Zhang Tianyuan proposed leaving the grassland to reclaim a city, and Tong Wenshi urged the group to return to the Imperial Capital because its radio station transmitted emergency broadcasts nationwide.
• Zhang Tianyuan agreed to change the broadcast so survivors across the country would learn that the Mutual Aid Society had arrived.

Zhang Tianyuan’s group picked up a distress call from an unknown woman, then prepared a five-hundred-person expedition to the Imperial Capital while the settlement organized its move south. The expedition set off through heavy snow with Ding Jingye among its members.
