Background / History

Su Yi was a Baiqiao University student from Huaxia before he and other Earthlings were transported to the Desolate Ancient era. During the crisis in Strange City, he protected Nan Xiaopao, wielded the Zhouwu Sword against demons, and became known among the survivors as an exceptionally powerful Half-Demon 12 19.

He received the Demon Emperor Divine Technique and Dragon Strength Pills through the Emperor Su Sect's phone-based group system. Although the technique is intended for the Demon Race, Su Yi understood and memorized it immediately, beginning a cultivation path centered on physical strengthening and demon power 3 4.

As his strength rose, Su Yi defended Xiwan City from demon armies, killed thousands of demon beasts, and made the Hundred Ridges his base. He cultivated demon cores, recruited formidable experts into the Emperor Su Sect, and became the Demon Lord whose name was feared throughout the Seven Dynasties and beyond 20 26 72 146.

His identity grew increasingly complicated. He was regarded as a Half-Demon, possessed unusual body constitutions, and was later associated with the Taicang Tyrant Body, the Tianshu Demon Star Dao Fruit, Golden Crow lineage, and the Emperor Su identity 146 281 433. Supreme Plain Heavenly Lord eventually revealed that she had raised him after he was delivered to Taisu Palace as an infant, though she was not his biological mother 618.

Su Yi later encountered the remnant souls of two past lives: Emperor Su and Qin Tianyun. Qin Tianyun revealed that he had created the Great Dao Phone, while both past lives subjected Su Yi to trials intended to temper his resolve. After inheriting their knowledge and memories, Su Yi chose to define himself independently: “there was only Su Yi” 653 655.

Appearance

Su Yi is a strikingly handsome young man with a cold, detached bearing. His hair eventually grows to his shoulders, and he commonly wears white robes, giving him the appearance of a refined swordsman rather than a demon ruler 127 518.

• Often dresses in white magical robes; he previously wore the Black Flood Dragon King Robe 127.
• Favors a calm, distant expression even when facing powerful enemies.
• Uses the Zhouwu Sword but dislikes openly carrying weapons merely for appearance's sake 109.
• When activating the Heavenly Emperor Divine Body, his body becomes crystalline and diamond-like, while his eyes turn silver 885.
• His combat aura can become oppressive enough to evoke awe even from close companions 897.

Personality

Su Yi is direct, pragmatic, and impatient with evasive conversation. He prefers people to state their intentions plainly and habitually answers threats with confidence rather than diplomacy 146 647.

His confidence often borders on arrogance, particularly after major breakthroughs, but it is supported by his willingness to cultivate relentlessly and challenge stronger opponents. He treats battle as both a necessity and a means of improving himself, repeatedly seeking experience rather than relying solely on pills or inherited power 20 413 655.

Despite his ruthlessness toward enemies, Su Yi is protective of those he considers his own. His decisions are frequently shaped by Nan Xiaopao's safety, the defense of Xiwan City, the growth of the Emperor Su Sect, and his responsibilities toward Su Lingding and Xiao Tianfeng 73 146 581 745.
