Background / History

Yi awakens at Linhai City Third High School as a D-rank Warrior, an outcome that disappoints those expecting an elite profession from the school’s top academic student. His outlook changes when he discovers Two Hundredfold Effort, a talent that lets him build skill proficiency at an extraordinary rate through repeated use. 1

He rapidly develops by repeatedly clearing dungeons and grinding monsters. In Goblin Forest, he turns Blade Draw into his principal combat technique, reaching Level 5 after defeating the Goblin Leader. He later trains in Wild Boar Forest, where Blade Draw reaches Level 10 and gains ranged sword-qi projection. 3 4 11

His rise draws the attention of the Dragon Kingdom’s senior figures. Following his actions in the Special Training Secret Realm and Abyss-difficulty dungeon, his potential is treated as a strategic asset whose exposure must be controlled. Leng Feng erases witnesses’ memories of some of Yi’s abilities, while Old Wang intends to cultivate him as a hidden card for the Dragon Kingdom. 72 73

After completing his First Class Change, Yi becomes an S-rank Radiant Sword Saint. His subsequent growth expands beyond ordinary professional standards: he commands vast numbers of clones, acquires and combines high-grade sets, develops Divine-grade swordsmanship, and ultimately gains control over the Abyss itself. 98 160 188 295 366

Personality

Yi is highly driven and treats repeated practice as the foundation of power. He is willing to endure unpleasant methods—such as consuming the Pigman King’s Heart raw—for permanent gains, and he repeatedly chooses difficult dungeons or training conditions to improve faster. 21 79 295

He is practical with resources and exceptionally perceptive when evaluating skills or equipment. He recognizes that Myriad Swords Return to Origin’s proficiency-draining flaw is uniquely compatible with his own talent, negotiates its price, and purchases it as a long-term investment. 47

In combat, Yi is calm, decisive, and can be ruthless. He interrogates Sato under torture for intelligence on Abe no Seimei, then kills him after obtaining the information. 86 Despite this severity, he shows respect for allies’ sacrifices and offers compensation to the Dragon Skeleton Battle Group after the Secret Realm operation. 72
