Background / History

Liu Feng is a transmigrator who was born into the Uchiha clan. His parents died during a mission, leaving him under the protection of his grandfather, Uchiha Sou, the clan's Great Elder and strongest fighter. His system awakened when he began refining chakra at age five. Aware of the dangers of the shinobi world, Liu Feng initially concealed his talent and kept a low profile. 1

After graduating from the Ninja Academy, Liu Feng's defeat of Uchiha Fugaku exposed his strength to both the Uchiha and Konoha's leadership. Sou began positioning him as a possible future clan head, while Hiruzen Sarutobi viewed the gifted Uchiha with concern. 1 4

Liu Feng used the system's Trial Space to defeat projections, acquire techniques, and accumulate points. He rescued Kushina Uzumaki, fought in the Second Shinobi World War, and repeatedly acted independently of Konoha's leadership—including retaining the Five-Tails and attacking Iwagakure without authorization. 15 49 51

Following the war, Liu Feng's power continued to grow beyond the contemporary shinobi world. He developed Kirigakure through subordinates such as Mei Terumi and Pakura while largely avoiding day-to-day governance himself. 81 142

After defeating the Otsutsuki Main Family, Liu Feng used the system's newly unlocked interworld travel function to enter the Pirate World. The system installed him as a Celestial Dragon, altering Mary Geoise's collective cognition so that his identity appeared legitimate. 202 204

In the Pirate World, Liu Feng accumulated Haki, Devil Fruit powers, powerful swords, and political influence. He conquered Wano Country, destroyed the Four Emperors, eliminated the pirate era, defeated the Five Elders and Imu, and absorbed the Pirate World into his system space as its ruler. 215 216 288 298 311

He later travels to the Bleach world under the identity of an ordinary Soul Reaper Academy student, using Spiritual Body Transformation to integrate into its setting while retaining his previous powers. 312

Appearance

Liu Feng is introduced as a handsome young Uchiha with a youthful appearance. Although nearly twenty years pass during his time in the Pirate World, his outward appearance does not change. 1 299

• Possesses Sharingan-derived eyes whose appearance changes with each major evolution.
• Uses a Konoha forehead protector after becoming a formal shinobi. 1
• In Ten-Tails Mode, manifests a Sage Robe and nine Truth-Seeking Orbs. 84

Personality

Liu Feng is pragmatic, self-assured, and intensely focused on personal power. He values tangible gains over reputation, saves system points when possible, and views strategic restraint as preferable to being exploited by others. 36 63

He is habitually laid-back about administration and delegates extensive responsibilities to others, particularly Mei Terumi. However, he is willing to intervene decisively when his authority, allies, or interests are challenged. 106 196

Liu Feng can be protective and affectionate toward people close to him, but his mercy is selective. He is capable of intimidation, coercion, and extreme violence against enemies or populations he considers obstacles. 107 215 216
