Chapter Summaries

Yinsen and Tony retrieved the Energon Cube Manufacturing Device from beneath an Egyptian pyramid, and Yinsen gave it to Tony as a souvenir. Before leaving Earth for a while, Yinsen arranged for Bumblebee to protect Mikaela and planned to judge how well Sam, Mikaela, and Dylan handled their responsibilities.

• Yinsen traveled to Egypt with Tony, opened a portal beneath the pyramid, and removed the hidden Energon Cube Manufacturing Device.
• Yinsen recorded the device’s structure in his Book of Inheritance and handed the miniature device to Tony, who planned to study its technology.
• Yinsen returned to Los Angeles and told Senator Kevin Smith that he would search for a water-rich meteorite, then bring his crew to Earth on a future visit.
• Yinsen told Optimus Prime that the Matrix of Leadership was on Earth and hired Bumblebee to protect Mikaela while he was away.
• Yinsen used the Space-Time Pointer to ensure that no more than three months would pass on Earth during his absence, and planned to assess Sam, Mikaela, and Dylan before deciding whether to give them greater rewards.

Yinsen sent Tony and Diana back to their respective worlds after their visit aboard the Prinz Eugen, then found the crew in the training room bullying the newcomers. The chapter ended with Selene defeating Galahad while a bruised Mordred watched nearby.

• Tony declined to visit another world and decided to return to his own universe, while Diana also chose to go home and resume protecting humanity.
• Diana teased Yinsen about Ada and Selene, and he spent the night reassuring her before sending her and Tony back to their worlds the next day.
• Yinsen noted that his next visits to the Marvel and DC Universes would occur at different intervals because he had locked onto their timelines differently.
• Yinsen went to the training room and realized the crew had been roughing up Mordred and Galahad.
• Selene disarmed Galahad and held her short sword to his throat.

Yinsen learned that O'Connell had defeated Mordred in an unarmed duel after quietly improving his skills, while Selene's spar with Galahad showed the young knight how far he fell short of the crew. Galahad assessed the ship's formidable fighters and felt fortunate that he and Mordred had been sent aboard.

• Yinsen asked Logan who had defeated Mordred, and Logan indicated O'Connell.
• Yinsen learned that O'Connell had completed his potion-enhanced physical improvement and had beaten Mordred using combat techniques taught by Logan.
• Galahad's spar with Selene revealed that he was far weaker than the crew's experienced fighters.
• Galahad learned that Diana was a goddess and that Yinsen was a demigod capable of fighting her without magic.
• Galahad learned about Logan's Healing Factor, Adamantium bones, and combat experience, and felt fortunate to be aboard the ship.

Galahad lost a sparring match to Selene and learned more about the Prinz Eugen’s powerful crew and lack of a dedicated doctor. As Yinsen prepared Laura’s enhancement, she asked him to move her foot claws to her hands, prompting him to make a special potion.

• Selene defeated Galahad in a sparring match, healed the small cut on his neck, and Jonathan revealed that she was the ship’s Death Dealer rather than its doctor.
• Jonathan asked why the ship had no doctor, and Yinsen explained that Selene, Annette, potions, and the crew’s healing abilities could handle illness and injury.
• Galahad and Mordred resolved to study and improve, while Yinsen arranged for them to learn basic knowledge before considering enhancement.
• Yinsen offered Laura an Enhancement Potion, but she asked to have the Metal Claw on her foot removed or transferred to her hand.
• Yinsen began making a special potion to fulfill Laura’s request.

Yinsen developed a custom Enhancement Potion for Laura that would improve her appearance and reshape her claws into versatile weapons. Laura began the lengthy enhancement, only to discover that the process was much less comfortable than she had expected.

• Laura asked Yinsen to make her prettier, give her longer legs, and remove or relocate the claws on her feet.
• Yinsen proposed turning Laura’s metal claws into painless, extendable nails, and consulted Logan as he refined the design.
• After more than half a month of adjustments, Yinsen created a formula that gave Laura extendable metal nails and concealed blades in her arm, elbow, and palm.
• Yinsen included beautification, body sculpting, and Mental Power enhancement in Laura’s custom potion, which required her to undergo the procedure in special equipment.
• Annette began Laura’s enhancement, and Laura realized that the process was uncomfortable.

Laura completed her enhancement and began adapting to her new abilities, while her changing appearance alarmed Logan by coming to resemble Deathstrike. Yinsen then discussed possible training paths with Jonathan and O'Connell, who considered learning to use Magic Energy in combat.

• Laura completed her enhancement, adapted to her new claws with Logan’s help, and noticed her appearance becoming more refined.
• Logan told Yinsen that Laura was starting to resemble Deathstrike, and Yinsen agreed the resemblance had become noticeable.
• Yinsen turned to the crew’s training needs and learned that Jonathan wanted to master Selene’s ability to hide in darkness.
• O'Connell asked whether he could learn Magic Energy, and Yinsen said he could use it to strengthen his combat ability.

Yinsen checked in with the Prinz Eugen's crew and discussed their next destination with Ada as they sailed toward the Sea of Miracles. Their calm journey ended when a powerful blizzard and numerous enormous whirlpools appeared ahead, leaving them with the choice of facing the hazards or turning back.

• Yinsen learned about the crew's goals and needs, while Evelyn, Jonathan, O'Connell, Imhotep, and Anck-Su-Namun continued their pursuits and training.
• Yinsen and Ada discussed their route across the Stormy Seas and wondered whether their unusually calm voyage came from good luck.
• Hill issued a Level Three Alert, and the crew gathered on the bridge.
• Hill reported an approaching blizzard and abnormal turbulence, while Eugen identified rapidly falling temperatures and predicted several enormous whirlpools.
• Hill said the whirlpools would be difficult to avoid unless the Prinz Eugen turned back.

Yinsen and the crew of Prinz Eugen encountered a blizzard and a sea packed with whirlpools that made turning back impossible. Yinsen plotted a route through the whirlpools using their rotational force, and the crew strapped in for the dangerous crossing.

• Yinsen ordered Eugen to project the weather and whirlpools ahead, revealing a blizzard and densely packed, dangerous currents.
• Hill recommended stopping, but Eugen warned that the currents were carrying Prinz Eugen toward the whirlpool region.
• Yinsen ordered the ship to turn around, but Eugen calculated that the currents would likely drag it broadside into a whirlpool before it could finish turning.
• Yinsen rejected the perilous passages between whirlpools and chose a route through their rotations, using centrifugal force to escape each one.
• Eugen plotted a twisting route through at least seventy whirlpools, and the crew buckled into their seats as Prinz Eugen began its rapid drift.

Yinsen and the crew guided the Prinz Eugen through a dangerous region of whirlpools, then approached a suspicious island surrounded by reefs and sunken ships. As the whirlpools vanished behind them, the temperature abruptly changed from extreme cold to summer heat.

• Yinsen activated the Prinz Eugen's Energy Defense Layer and steered the ship through the whirlpools using Eugen's calculated route.
• Yinsen and the crew spotted an island as the snow eased and the whirlpools began to slow and disappear.
• Yinsen ordered Eugen to leave the whirlpools and cross the calmer waters, and the final whirlpool vanished as they departed the region.
• Yinsen had Eugen display the island, revealing shallow reef-filled waters and countless wrecked ships beneath the surface.
• Hill reported that the outside temperature had jumped from minus forty to twenty-five degrees Celsius in an instant.

Yinsen discovered that a Spatial Maze was trapping Prinz Eugen in a loop around a beautiful island, and he decided to investigate the spatial and temporal energy there. He brought everyone ashore by Quinjet and began exploring with Little Ou while the others prepared a camp.

• Yinsen ordered Prinz Eugen to circle the island, then leave, but the ship repeatedly encountered an identical island and returned to it.
• Yinsen identified the surrounding waters as a Spatial Maze and sensed a trace of temporal power within it.
• Yinsen decided to investigate the island and considered bringing Little Ou, while the others insisted on joining him.
• The group flew to the island by Quinjet and landed on a beach, where Laura and Logan sensed the island's welcoming goodwill.
• Yinsen said the island's grass was ordinary and set out with Little Ou to explore while the others built a camp.

Yinsen, Laura, Ada, and Little Ou searched the island for the Magic Heart and a magic stone, eventually finding a hidden, water-filled cave with an unfamiliar energy fluctuation. Yinsen realized the river’s energy could detect anyone entering it, suggesting that someone or something on the island had discovered them.

• Laura volunteered to accompany Yinsen, and Ada joined them in her Combat Suit.
• Yinsen led Laura, Ada, and Little Ou across the plain toward the mountain while Little Ou failed to sense the Magic Heart or magic stone.
• The group followed the river upstream toward the mountain and found a concealed cave filled with water.
• Little Ou sensed something near the cave, and Yinsen detected an unfamiliar energy fluctuation inside it.
• Yinsen entered the river and realized its energy would alert whoever or whatever had released it to anyone entering the water.

Yinsen, Ada, and Laura explored a cave and uncovered a Hibernation Pod containing a girl named Betty, who believed she was an Imperial Military Academy student. Betty discovered she had slept for 873 years, leaving the group facing the mystery of how she came to be in their world.

• Yinsen, Ada, and Laura searched the cave and found a concealed high-tech device at its deepest point.
• Yinsen activated the device, revealing a Hibernation Pod and waking the girl inside.
• The girl introduced herself as Betty, a Warship Piloting Science Student at the Imperial Military Academy, and questioned whether the group were students taking an assessment.
• Yinsen told Betty that he and his companions were not a rescue team, and she cautiously asked who they were and why they had come.
• Betty checked the pod's holographic data and saw that her hibernation had lasted 873 years.

Betty woke after 873 years in a failing Hibernation Pod and met Yinsen, Ada, and Laura, whom she suspected were natives. After Yinsen made the pod disappear, they left the cave with Betty and headed back to shore, where he hoped to learn what she knew about the island.

• Betty confirmed she had slept for 873 years and discovered that most of the Hibernation Pod's systems had failed.
• Betty thanked Yinsen for saving her and learned that he and his companions had never heard of the Imperial Military Academy.
• Betty noticed Little Ou and Yinsen's unusual equipment, while Yinsen suspected she could explain the island's mysteries.
• Yinsen put away the Hibernation Pod, and Betty followed the group out of the cave despite her failing weapons and detector.
• Laura rejected the magic stone offered by Laura, and Yinsen decided to return to shore with Betty rather than continue exploring the mountain.

Yinsen questioned Betty about the world and learned that the ocean realm was an artificial military training ground created by the Empire, whose citizens regarded the local natives as expendable lower life forms. Betty revealed that she saw Yinsen as one of those natives, but he calmly accepted the truth.

• Yinsen noticed that Betty showed remarkable stamina despite having just awakened from more than eight hundred years of hibernation.
• Yinsen brought Betty to the camp, where she accepted water and ate a nutritional supplement.
• Betty asked whether Yinsen’s people had made the bottle, and Yinsen urged her to explain what she knew about the world.
• Betty admitted that she knew where they were and warned Yinsen that the truth might be difficult to accept.
• Betty explained that the Empire had created the ocean world, its monsters, islands, and native Low-Level Life Forms as a military training ground.
• Betty revealed that the Empire considered people like Yinsen expendable, and she was relieved when he remained calm.

Yinsen learned how Training Ground No. 1001’s assessment worked and heard how Betty became stranded on the permanent island after her commander died and her team fell apart. Betty had been waiting in hiding for rescue, but Yinsen’s arrival raised new questions about the island’s defenses and purpose.

• Betty explained the assessment’s sea zones, team scoring rules, and the Energy Field surrounding Training Ground No. 1001.
• Yinsen asked about the Energy Field’s exit, and Betty explained that a specialized controller could open a temporary passage through it.
• Betty recounted how her team lost its commander, argued over whether to continue, and eventually split apart on the island.
• Betty said she fled her classmates after they tried to take her equipment, sent a distress signal from a cave, and entered hibernation when rescue did not arrive.
• Betty explained that the island stayed afloat permanently and that defenses were supposed to keep ordinary ships away, though they may have stopped working.
• Yinsen realized he had passed through the island’s storms and whirlpools despite those supposed defenses.

Yinsen learned more about Betty’s origins and the Empire’s control over the Training Ground, then discussed with his companions whether the Empire had abandoned it and what the guild’s role might be. The group prepared to leave while resolving to stay cautious about possible opposition.

• Betty hesitated to tell Yinsen that trainees’ native helpers were often destroyed, then questioned him about the outside world and his plans to cross the Stormy Seas.
• Yinsen told Betty to rest in the shelter while he kept watch, then joined his companions for a meal and shared what he had learned.
• Logan warned that leaving the Training Ground could provoke the Empire, while Ada and Yinsen reasoned that the Empire might have lost control or abandoned the place.
• The group suspected the guild served the Empire by controlling local technology and magic stone trade, and Yinsen considered seeking more information from it.

After Betty revealed that Miracle Island used a special technology, Yinsen decided to investigate the island and search for a device connected to time. While his companions trained and prepared to gather information, he spent his days studying blades of grass, leaving Betty frustrated by his lack of visible progress.

• Yinsen changed the plan and decided to send Ada and Selene ashore with him to investigate Miracle Island and gather information about the Empire.
• Yinsen told the group he suspected the island's technology involved time and hoped to find a device that would deepen his understanding of it.
• Maria Hill began training in the Holy Light, while Mordred and Galahad worked on swordsmanship and magical power.
• Maria Hill succeeded in sensing a small amount of the Holy Light, and Mordred trained harder as she compared herself with Galahad.
• Yinsen spent several days lying in the shack and staring at blades of grass instead of searching the island, prompting Betty to ask when they would leave.
• Yinsen told Betty he was looking for something and agreed that it would come to him if he kept lying there.

Yinsen discovered that the island’s time energy was keeping its plants in a perfect, rapidly recovering state, and he prepared to extract it after his companions finished their training. He drained the energy and flew back to the waiting Quinjet, leaving Betty astonished by his abilities.

• Yinsen found that plants across the island rapidly recovered from damage before stopping at a fixed state, revealing the island’s time-related technology.
• Yinsen told Betty and his companions they were ready to leave, then explained that the island itself held the time energy he had been seeking.
• Betty learned that Yinsen’s ship was a Quinjet from the Prinz Eugen, which disengaged its Optical Invisibility and landed on the island.
• Yinsen released the Space-Time Pointer’s restraint and drained the island’s time energy as the island and his hand glowed.
• Yinsen floated off the island and flew toward the Quinjet while Betty watched in disbelief.

After returning to the Prinz Eugen, Yinsen explained that absorbing temporal energy had made his Storage Space a Personal Space, expanded its capacity, and let him stop time inside it. Betty explored the ship and grew increasingly convinced that the supposedly local vessel was far more advanced than she had imagined.

• Betty questioned Yinsen about how he could fly, but he said it came naturally to him.
• The Quinjet returned to the Prinz Eugen, whose sudden appearance and steamship-like exterior stunned Betty.
• Yinsen assigned Ada to show Betty the Living Area while restricting her access to crew-only sections.
• Yinsen destroyed his Space-Time Ring and explained that he could now control his Personal Space directly and stop time inside it.
• Yinsen said the space was about the size of a basketball arena and offered to upgrade the team's Storage Items.
• Betty reached the bridge, saw its advanced controls and holographic displays, and wondered if she had really slept for only a little over eight hundred years.

Betty explored the Prinz Eugen while Yinsen extracted Spatial Energy from the sea around the island. As the ship continued circling, Yinsen studied the energy and discovered it could reveal an image of the island, leaving the group with an unexpected clue about its nature.

• Betty wondered whether another civilization had occupied the Training Ground after she found that the Prinz Eugen used an unfamiliar language.
• Yinsen sensed that the Spatial Maze's energy still surrounded the island and had the ship circle it so he could absorb the scattered Spatial Energy.
• Betty stayed on the bridge with Yinsen, Maria Hill, and Logan until Logan took her to the cafeteria, where she later went to rest.
• Yinsen revealed that he had collected the remaining energy quickly and had slowed down mainly to study it.
• Yinsen asked Logan and Hill to focus on a point of light, and they saw an image of the island before the light changed from blue to silver with a hint of gold.
