Jiang He deduced that Don Thousand planned to devour the Seven Barian Emperors to complete his revival, while Don Thousand ordered Vector to merge the Barian World with the real-world dueling world.

Jiang He acquired the Millennium Spellbook of Dark Alchemy Mark and three decks, then the story shifted to Professor Banner beginning an alchemy lesson at Duel Academy.

• Professor Banner began a practical alchemy lesson at Duel Academy, telling his students he could turn useless materials into gold.

Jiang He considered the cost of using his new Dark Great Evil God alchemy mark to create Pseudo-Millennium Items, then offered the items to his companions as protective gifts. The girls chose their preferred items, and Tori Meadows shyly accepted one as well.

Jiang He and Rio Kastle faced Mr. Heartland and Jellyfish Senpai in a tag duel as Mr. Heartland rapidly summoned three [Gorgonic Flies] and used them to Xyz Summon [Number 1: Gorgonic Fly King].

• Jiang He, Rio Kastle, Mr. Heartland, and Jellyfish Senpai began a tag duel with 4000 Life Points each, and Mr. Heartland took the first turn.
• Mr. Heartland summoned [Gorgonic Fly] and activated [Infernal Proliferation] to Special Summon two more copies from his hand.
• Mr. Heartland used the three [Gorgonic Flies]’ effects to raise their Levels to 8, then Xyz Summoned [Number 1: Gorgonic Fly King].

Rio Kastle summoned Ice Beast Zerofyne to challenge Mr. Heartland’s Gorgonic Fly King after he sent her Number 103: Ragnafinity to the Graveyard. She activated Zerofyne’s effect to reduce an opposing monster’s ATK to 0, leaving Heartland’s boast poised to backfire.

• Mr. Heartland used Beelzebub Infection to send Jiang He’s Geomathmech Magma and Rio Kastle’s Number 103: Ragnafinity from their Extra Decks to the Graveyard, then set a card and ended his turn.

• Jellyfish Senpai’s attack threatened to destroy [Ice Beast Zerofyne] and inflict damage equal to its 2500 attack, so Rio Kastle revealed her trap [Ice Crystal].

Rio Kastle used Ice Crystal to destroy her own monster, avoid Stealth Kragen’s effect, and damage the opposing team, but Jellyfish Senpai revived two Stealth Kragen Spawn with the same abilities. Jiang He remained unimpressed by the jellyfish’s boast about having no brain, leaving Jellyfish Senpai angry.

Jiang He reflected Jellyfish Senpai’s effect damage onto both opponents with [Ecorce the Forest Spirit], leaving Jellyfish Senpai and Mr. Heartland at 1500 LP each. When Jellyfish Senpai destroyed the monster, Jiang He revealed its protection effect had already prevented further effect damage that turn.
