Oura explained Ken Ichijouji's crimes in the Digimon World, and Satoshi Ichijouji reunited with his brother before Zheng Fan restored Satoshi to his younger form. Zheng Fan then caught up with the older Chosen Children, offering help and instruction while finding himself unable to answer several of their questions.

• Oura told Zheng Fan that Ken had used dark energy, Black Dark Rings, and Dark Towers to control Digimon and alter the Digimon World before Oura and his friends defeated him.
• Satoshi Ichijouji wept and apologized to Ken, then Zheng Fan shrank Satoshi into the appearance of an eleven- or twelve-year-old boy.

• Marcus Damon and Tai greeted Zheng Fan, and Zheng Fan praised Sora Takenouchi's progress before learning that T.K. Takaishi had died and returned to life.
• Zheng Fan gave T.K. Takaishi private instruction and decided to speed his body's growth, then listened to questions from Joe Kido, Izzy Izumi, Matt, Sora Takenouchi, and Mimi Tachikawa without finding satisfying answers.

Oura struggled to accept that his brick-hauling efforts were ineffective, while Zheng Fan and the others continued advancing against the Dark Towers. When Oura’s team encountered a Knightmon blocking their route, they restrained him and relied on Oura to bring down the nearby Dark Tower.

• Marcus Damon left after he and Oura disagreed over how to help rebuild the Digimon World.

• Oura realized that his brick-hauling had contributed little, while Marcus Damon had been pushing the front forward and Zheng Fan and Marcus Damon had rejected a direct attack through the Great Vortex.
• Oura’s team encountered a Knightmon blocking their route, and T.K. Takaishi and Iori judged that Knightmon was carrying out a mission rather than acting as their enemy.
• Hawkmon, Armadillomon, Pegasusmon, and Nefertimon restrained Knightmon, leaving Oura to bring down the Dark Tower.

Oura and Veemon freed Eagle-Eye Beast from a Black Dark Ring and entered the Dark Tower area, where Arukenimon trapped them and revealed she controlled the Digi-Destined Emperor. Two days later, a Chosen Child named Zeng Xiao Xian rescued Oura and Veemon and flew away with his partner, Flymon.

• Two days later, Zeng Xiao Xian cut Oura and Veemon free, introduced Flymon as his partner, and flew away.

Izzy inferred that Zeng Xiao Xian was connected to Zheng Fan after studying the footage, while Arukenimon and Mummymon learned that a powerful Mega-level fighter had appeared and were ordered to destroy the Holy Stones. Ken declared that Zeng Xiao Xian would not lose his way, and Arukenimon and Mummymon prepared to meet him while worrying that they needed a Mega to protect them.

• Izzy paused the footage and concluded that Zheng Fan knew Zeng Xiao Xian, though Tai argued that Zheng Fan might simply have known about Oura and his rescuer.

Arukenimon used her flute to control Stingmon and Armadillomon, then pressured Zeng Xiao Xian into halting the fighting and exposing why Ken Ichijouji had become the Digi-Destined Emperor. When Stingmon wounded Zeng Xiao Xian, he and Oura acknowledged their bond, allowing Veemon EX and Stingmon to fusion digivolve into Paildramon.

• Arukenimon's flute made Stingmon and Armadillomon attack their allies, while Veemon EX held them back as Oura, Iori, and Zeng Xiao Xian were forced out of the passage.

The Chosen Children and their Digimon fought Digimon unleashed in the Human World by Dark Towers, destroying one tower and defeating its attackers.
