• The fragments of File Island gradually drew together.

As File Island’s fragments reunited, Zheng Fan and the children encountered Mimi, Palmon, and the evolved Mastermon, then reunited with T.K., Izzy, and their partners. The group decided to travel to Infinite Mountain, where the events had begun.

• Zheng Fan watched File Island’s fragments align and merge with Tai and Joe, while Tai tested the crushing force with a boulder.
• Zheng Fan and the children found Mimi Tachikawa, Palmon, and Mastermon, whom Zheng Fan recognized as the evolved Elderlymon.

• Zheng Fan and Mastermon agreed to lead the group to Infinite Mountain, and MegaKuwagamon and the children joined them.

Zheng Fan and his companions traced strange fluctuations to Graveyard Mound, where MegaKuwagamon’s attack unleashed a powerful dark aura. After Cardmaster Twister accidentally sent the darkness toward Infinite Mountain, Zheng Fan contained it and the group prepared to isolate it inside a barrier.

• Zheng Fan agreed to teach both MegaKuwagamon and Kabuterimon to fight like Greymon, then helped Cardmaster Twister stop Triceramon from using Volcanic Cannon.
• MegaKuwagamon and Palmon detected strange fluctuations east of the forest, and the group traveled to the burned remains of Graveyard Mound while Tai and the others stayed behind.
• Mastermon and Cardmaster Twister examined a stone platform with a strong dark aura, and MegaKuwagamon smashed it, releasing a surge that began corrupting Zheng Fan and Cardmaster Twister.
• Cardmaster Twister created a teleportation formation and sent the dark aura toward Infinite Mountain, so Zheng Fan knocked him out of Mastermon’s barrier and used Lesser Northern Sea Devouring to contain the darkness.
• Cardmaster Twister redirected the teleportation destination to open sea, and Zheng Fan spat the darkness into the barrier while MegaKuwagamon piled earth and stones into walls around it.

While Zheng Fan and Mastermon investigated the growing darkness near Infinite Mountain, Tai and the others were ambushed by Deathmon and fought him using their Digimon and Zheng Fan’s training. Deathmon plunged the forest into darkness, and the group was left relying on the light of Joe Kido’s Digivice as it indicated Gomamon was nearby.

• MegaKuwagamon apologized for the disasters, while Zheng Fan noticed the darkness around Infinite Mountain growing thicker.
• Tai and Joe Kido demonstrated the Universal Physical Arts, and they sensed a hidden presence and attacked the red-cloaked Bakemon, revealing him as the Ultimate Digimon Deathmon.

• The Night Dawn Sword’s Sword Spirit agreed to let a gentle voice make one strike against Phantomon before returning control of the blade.

Garurumon and the other Digimon defeated Phantomon with a coordinated attack, while Sora Takenouchi and the other Chosen Children restrained and erased it with their Digivices. Zheng Fan, Mastermon, and Cardmaster Twister investigated the weakened darkness in the cave and discovered a vast cavern filled with openings that spewed deadly flames.

• Garurumon arrived and pierced Phantomon with his new Garuru Crystal Sword, allowing the Digimon to strike together and grievously wound it.
• Phantomon lunged at the Chosen Children, but Sora Takenouchi immobilized it with her Digivice and the others helped erase it.
• Mastermon sensed that the cave's dark power had weakened, and Zheng Fan agreed to investigate with Mastermon and Cardmaster Twister.
• Cardmaster Twister gave Mastermon his teleportation card, and MegaKuwagamon broke through the earthen barrier to reveal the shaft beneath it.
• Zheng Fan and Mastermon found a hollow space behind the shaft wall and entered a huge cavern whose openings poured out scorching flames.

Zheng Fan discovered that the forest had been sacrificed to let Dark Power pass through the flames, then found the Night Dawn Sword badly damaged and Cardmaster Twister dead. After Xiao, the sword’s newly awakened Sword Spirit, fell asleep, Mastermon scattered Ancestor Angemon’s Bitcoins to protect the area from another disaster.

• Zheng Fan realized the Void lay beyond the flames and concluded that the forest had been sacrificed to let Dark Power through.
• Mastermon pulled Zheng Fan from the cavern, where they found MegaKuwagamon gravely wounded and Cardmaster Twister reduced to his head.

• Zheng Fan removed the Dark Power from the blade, and its Sword Spirit named Xiao before falling into a deep sleep.
• Zheng Fan warned the children to avoid negative emotions, then Mastermon scattered Ancestor Angemon’s Bitcoins across the marked area and left.

The group discussed how negative emotions allowed darkness to control Digimon, then reached the foot of Infinite Mountain and planned a route past its patrols. Izzy weighed the risks of sneaking through or fighting as they prepared to approach the mountain.

• T.K. asked Mastermon to use his heart-affecting power to cheer Izzy up, but Mastermon avoided using it casually.
• Zheng Fan explained to Izzy that negative emotions, rather than darkness itself, controlled Digimon, and the group discussed whether emotions could be balanced.
• The group reached Infinite Mountain and spotted Andromon among the Guardromon patrols.
• Zheng Fan connected Mastermon to Izzy's laptop so Izzy could use Mastermon's vision to map the patrol routes.
• Izzy compared possible routes and considered how many Champion Digimon Mastermon and Zheng Fan could fight, while worrying that Numemon would slow the group down.

Zheng Fan and the others used Genai’s data file to disable the Factory patrols and reach Infinite Mountain, where they prepared to clear the Black Gears despite disagreeing over the danger. The chapter ended with Zheng Fan choosing to help Mastermon remove them.

• Genai appeared through a saucer-shaped device, confirmed Mastermon’s history, and sent Izzy a program to disable mechanical Digimon.

• The group climbed to the mountainside, where Zheng Fan and Mastermon disagreed about whether to leave the Black Gears alone or destroy them.
• Mimi realized the Black Gears might be meant to provoke conflict, and Zheng Fan agreed to help Mastermon clear them.

Zheng Fan and the others fought Lost Satanmon as he explained that the dark Digimon had come from another Digimon World to prepare for a crisis. With Black Gears pouring from beneath Infinite Mountain, Tai and Joe Kido left the battle to find Leomon while the others continued fighting Lost Satanmon.

• Zheng Fan and Mastermon destroyed Black Gears until Lost Satanmon revealed himself and asked to explain the dark Digimon’s origins.
• Lost Satanmon said the dark Digimon came from another Digimon World and had been preparing for a crisis, but Mastermon’s question about their leaders went unanswered as the battle began.
• Zheng Fan and the Chosen Children’s Digimon wounded Lost Satanmon, while Mastermon’s halo destroyed most of the Black Gears feeding his strength.
• Izzy Izumi and Joe Kido discovered that Leomon was sending Black Gears from beneath Infinite Mountain, and Tai and Joe Kido set out to stop him.
• Mastermon urged Zheng Fan to stop the children, but Zheng Fan rebuked him and insisted they focus on their own fight as Tai and Joe Kido descended the cliff.

Tai and Joe tried to warn Leomon that dying Digimon were turning into Black Gears, while their Digivices empowered him. Lost Satanmon overwhelmed the defenders, consumed the Black Gears, and grew to cover File Island, but Sora’s crest and Patamon’s call prompted the Digimon to channel their Digivices’ power to him.

• Tai recognized that dead Digimon were becoming Black Gears and urged Leomon to stop more from dying as Andromon attacked.
• Joe rescued Tai from Guardromon but broke his leg, and the boys threw their Digivices to Leomon, whose power surged with their light.
• Lost Satanmon struck Birdramon, but Cactismon revealed a girl holding a Digivice, and five Digivices’ light weakened Lost Satanmon.

• Zheng Fan used the Digivices and the Night Dawn Sword's tassel to attempt a soul-summoning ritual, and Xiao told him that Angemon was trapped with Lost Satanmon while Mastermon had already left.
• Izzy urged Sora to remember how she had used her power, and Sora shouted that she only wanted to keep anyone from getting hurt, causing her heart-shaped mark to shine.
• Sora's power of Love reached the spirit world, freeing Angemon and allowing Xiao to sever their remaining connection to Lost Satanmon.
• Angemon used the Holy Ring and his power to repair the Night Dawn Sword, then shrank through his earlier forms and became a Digi-Egg that T.K. caught.

Sora Takenouchi’s power of Love helped Biyomon become Lost Garudamon, but Lost Satanmon seized control of their new body and Biyomon flew away after tearing herself free. Genai then explained that the children needed to recover the Gate and find the Crests and Key, leaving Zheng Fan eager to learn how to return to his world.

• T.K. Takaishi celebrated Patamon’s Digi-Egg while Sora Takenouchi discovered that her power represented Love, and Lost Satanmon used his remaining strength to attack her.
• Biyomon shielded Sora Takenouchi from Lost Satanmon’s black light, digivolved into Hellfire Birdramon, and then became Lost Garudamon after Sora affirmed that Love could embrace everything.

• Zheng Fan cut lumber while the children and Digimon built a fortified ship and tested its attack-detection system.
• The ship was completed, but the Digimon and children could push it only a few meters before the earth piled up in front of it.
• Joe Kido stopped the group from destroying the ground and planned a new route with help from Izzy Izumi's calculations.
• Garurumon froze the ground, Cactismon embedded it with spikes, Greymon melted the ice, and Kabuterimon's charged Mega Cannon pulled away rocks to clear a path toward the sea.
• Joe Kido told everyone to try moving the ship again.

The children sailed from File Island aboard the Lion and Zheng Fan explained the dangerous Six Paths Breakthrough, a cultivation method tied to his deal with Digimon World. Matt broke through and chose to learn it, inspiring the others, while Zheng Fan went to retrieve Tai’s goggles from the sea.

• Tai, Mimi, and SaberLeomon launched the ship, and the children named it the Lion after SaberLeomon.
• Zheng Fan warned the children that their growing strength could threaten world peace and explained the difference between Qi Deviation and falling into darkness.

• Zheng Fan told the children to remain aboard the Lion and dived into the sea to retrieve Tai’s goggles.

After Tai fell into the sea, Whamon appeared and asked the children for help with something hurting inside its stomach. Tai and Agumon entered Whamon to investigate, and the chapter ended with them being blasted skyward in a spout of water.

• The Lion lurched, knocking Tai into the sea, and Agumon jumped after him before Palmon pulled Agumon back aboard.
• Whamon rose from the ocean and attacked, but Izzy spoke with it and learned that its stomach hurt because something was inside.
• Tai insisted on helping Whamon, gave it his Digivice to prove he could not digivolve, and entered its stomach with Agumon.
• Tai and Agumon swam through Whamon's insides while the others worried they had lost contact with Zheng Fan and could not find them.
• Whamon expelled a towering column of water, sending Tai and Agumon skyward as they cried for help.

Zheng Fan fought off Digimon pursuing him across the sea, then rushed to save Tai and the others after sensing dark energy near Whamon. He mistakenly wounded Whamon, healed it after learning Tai had destroyed a Black Gear inside it, and the energy he released caused T.K.’s Digi-Egg to hatch.

• Zheng Fan dodged Tuna Beast’s fatal attack and a coordinated Seadramon assault before escaping his pursuers behind a coral reef.

• Zheng Fan apologized and healed Whamon by gathering data energy, then released a restorative ripple that made T.K.’s Digi-Egg hatch.

Zheng Fan and the children learned that Lost Garudamon had wounded the sea Digimon while stealing something from an underwater convenience store, and Whamon led them there. On the way, Whamon explained Dragomon’s history, while Zheng Fan tested the pearl he had taken and discovered it could create a water-free space; the group arrived at a submerged cavern and winding tunnel.

• Izzy Izumi warned that Zheng Fan helping the partner Digimon digivolve might permanently fix their forms at Champion level, while Joe Kido worried his power would attract Digimon seeking evolution.
• Whamon revealed that Lost Garudamon had killed MegaSeadramon and wounded the sea Digimon, and he identified Tai’s Digivice as something connected to the theft.
• Tai asked Whamon to take the group to the sunken convenience store, and Zheng Fan dived alongside Whamon rather than entering his stomach with the children.
• Whamon recounted how Agumon survived the disaster on File Island, became Aquadramon, and eventually evolved into Dragomon after choosing a path that trapped him underwater.
• Zheng Fan used data energy to make Dragomon’s pearl create a stable, three-meter water-free space, then followed Whamon and the others to an underwater cavern with a sloping tunnel.

Zheng Fan and the children reached a hidden convenience store, where they tricked Drillmon and dealt with the Black Gear controlling him. When Poyomon disappeared inside the damaged store, T.K. sensed where he was and ran to find him.

• Whamon brought the group into a vast culvert, and Zheng Fan emerged from the water, quickly drying himself and his clothes.
• Mimi spotted a convenience store, and Drillmon barred the group until Izzy convinced him that an Ultimate-level Lost Satanmon would not need a password.
• The children saw a Black Gear on Drillmon, and Mimi had Palmon digivolve into Cactismon, whose punch sent Unimon crashing into the convenience store and wrecking its contents.
• T.K. discovered Poyomon was missing and rushed into the dusty store, asking Zheng Fan to help find him.
• Zheng Fan dispersed the dust with his aura, and a silver light appeared at T.K.'s chest as he sensed Poyomon's location and ran toward him.

The group recovered the seven Keys and continued across the ocean, surviving a dangerous attack that awakened Tai and Matt’s attributes. After a long voyage, they finally spotted land, while Ikkakumon and the other Digimon returned to the Lion.

• T.K. rescued Poyomon and the box of seven Keys, and Zheng Fan examined the Keys before the children chose them.
• Drillmon explained that it had been controlled by Devimon, then burrowed underground when it could not shrink enough to travel back with the group.
• An Ultimate Whalemon and Champion Black Whalemon attacked Whamon and the Lion; Zheng Fan killed Whalemon, and Tai and Matt awakened their attributes during the fight.
• Zheng Fan sensed that the group had reached land, and Tai climbed the mast to spot the shore before Sora took the spyglass and confirmed it with her Digivice.
• Joe called Ikkakumon back, and Ikkakumon fired Harpoon Vulcan into the sky as Tentomon flew toward it.
