Background / History

You Zhi was a martial-arts obsessive in his previous life who studied under numerous masters and sought legendary immortals in remote mountains. He died after suffering a qi deviation while secretly practicing a forbidden technique, then awakened in an unfamiliar, thinner body and quickly accepted that he had transmigrated. 1 6

In his new world, he became a Spirit Trainer with Assistant Goblin and Demon Lizard Yihao, spirits left behind by the body’s original owner. He also possesses a private “Yu-Gi-Oh!-Style Appraisal” ability that reveals information about spirits and Spell Cards—an advantage he deliberately keeps hidden. 6

After saving Phile Crawford from a Scyther spirit in Ilex Forest, You Zhi accepted Pegasus Crawford’s offer to tutor Phile in Spirit Duels, survival, and martial arts in exchange for access to the Crawford library. 4 6

Appearance

You Zhi’s body changed markedly after he began cultivating Strength-Weakness Mimicry.

• He initially awakens with unfamiliar, noticeably thin limbs. 1
• Early cultivation leaves his skin visibly smoother and improves his physical condition. 6
• After three weeks of training at the Crawford residence, he appears robust, healthy, and no longer resembles someone recovering from serious illness. 8
• Later, Alisa observes that his formerly sharp, dangerous presence becomes restrained enough for him to seem ordinary. 115

Personality

You Zhi is unusually adaptable and carefree under extreme circumstances; he accepts transmigration almost immediately and treats dangerous unfamiliar worlds as opportunities for adventure. 1 18 He is also a calculated risk-taker, knowingly returning to Strength-Weakness Mimicry despite recognizing that the technique killed him once before. 6

In battle, he is pragmatic, opportunistic, and notably unconcerned with conventional sportsmanship. He exploits openings, prevents enemies from fleeing, ambushes opponents alongside his spirits, and prefers tactics that deny an opponent the chance to execute their plan. 4 10 103

He does not judge power by its source. Although he will lie, manipulate expectations, and enjoy watching arrogant enemies collapse, he consistently acts against threats to others and refuses power that cannot remain under his control. 18 21 36 He also opposes monopolizing useful knowledge, eventually publishing what he knows of Xyz Evolution rather than hoarding it. 7 133

Abilities & Skills

Yu-Gi-Oh!-Style Appraisal

You Zhi can inspect a spirit’s approximate attributes, level, talent, lineage, and traits, as well as gain information about Spell Cards an opponent is preparing to use. 6 19

• Allows him to identify hidden effects and build counters before opponents reveal their strategy. 51 91
• Lets him recognize unusual forms, including World Legacies and enemy evolution states. 31 122
• He avoids openly demonstrating the ability when doing so could expose its existence. 95
• Mechanical Angel independently deduces that he can see through Pokémon traits. 111

Strength-Weakness Mimicry

A dangerous cultivation method that strengthens You Zhi’s body, adapts him to hostile conditions, and allows him to mimic aspects of other beings through spiritual power. 6 19

• Enhances his speed, endurance, strength, reactions, and flexibility beyond ordinary human limits. 8
• Can mimic Demon Lizard Yihao’s anatomy, granting claws, hardened skin, bone spikes, and the ability to use Slash. 19
• Reduces the mental pressure imposed by Dark Duels and automatically adapts his body to severe cold. 61 83
• Can refine radically different forms of energy, including Great Unity Panlong’s evil qi and the God of Orichalcos’ hatred. 22 104
• Its indiscriminate energy absorption is dangerous; You Zhi’s original use of a related forbidden technique caused his death. 1 6

Martial Arts

You Zhi is an experienced close-combat fighter who combines techniques from his previous life with spiritual power and spirit-derived skills. 6 20

• Teaches Phile practical Sanshou to build confidence and survival ability rather than turn her into a spirit fighter. 6
• Learns and employs Void Dragon Wheel, Water-Cutting Style, Void Resonance, and Swordsoul techniques. 20 89 105
• Uses physical combat alongside his spirits, including ambushes, joint attacks, and direct engagements against powerful enemies. 10 20 91
• Can combine martial techniques with spirit skills, such as Quick Attack, Psycho Cut, and Air Slash. 91 92

Spell Card Refinement and Duel Tactics

You Zhi refines Spell Cards quickly and uses them to control positioning, suppress abilities, force combat, or create decisive openings. 10 60 103

• Uses Final Assault Order to deny fleeing and force spirits into aggression. 4
• Uses Earthquake, Order to Retreat, Miniature Ray, and Axe of Fools to create favorable battlefield conditions. 33 46 62 96
• Can summon large numbers of Spell Cards without the physical strain that limits ordinary Trainers. 99
• Publicly shares his understanding of Xyz Evolution after demonstrating it in the Quartz Tournament. 133
