Background / History

Li Xuanxiao awakened after a demon attack in Ning'an City, having transmigrated into the body of a deceased yamen constable. The former body's memories revealed that Ning'an's weak authorities had tolerated demons preying on civilians, while the magistrate ultimately allowed them to hunt martial artists. Li survived the attack and discovered the Demon Slayer System, which awards Demon Points for killing demons. 1

He rapidly became Ning'an City's strongest martial artist by using Demon Points to enhance his cultivation and blade arts. After killing the Rat Fiend and clearing demons from Ning'an and its surroundings, residents came to know their unseen protector as “Lord Li.” 3 8 12

Li killed Ning'an's magistrate after the official repeatedly yielded to demons and sacrificed martial artists for his own safety. Although Inspectors Si Miaoyin and Ling Yan initially brought him to Pei Province to stand trial, the Ning'an constables testified that he had acted to protect the city. He was instead allowed to redeem himself through an investigation in Faxuan City. 13 16

During the Faxuan assignment, Li exposed Pure Land Temple's demonic Transformation Ritual, rescued the young monk Jingshan, and destroyed the Demon Monk and Mukade infestation beneath the temple. He later joined the Pei Province Demon Slayer Division's Mission Hall, choosing its flexible structure over the more regulated Patrol Hall. 18 20 23

After repeatedly accepting dangerous demon-slaying work, Li reached the Mystic Realm and became a key combatant in Pei Province's response to escalating demonic activity. He later returned to find the Demon Slayer Division devastated, then killed two Mystic Realm Demon Emperors who had attacked it. 37 45 46

Appearance

Li Xuanxiao is a youthful, handsome-looking young man who had only just turned eighteen during the Ning'an City incident. His age and appearance routinely cause others to underestimate his martial prowess. 6 29

• Has a notably youthful face. 6
• Is described as a handsome young man around Si Miaoyin's age. 29
• Wears the uniform of the Demon Slayer Division after joining its Mission Hall. 43
• His eyes can display golden Buddhist markings while using My Buddha Illuminates Seal. 31 32

Personality

Li is practical and survival-driven, immediately prioritizing cultivation and combat power after entering a world dominated by demons. He treats Demon Points, weapons, movement arts, and mission rewards as resources to be used efficiently. 1 24 25

He is resolute when faced with overwhelming pressure. Under Yang Zhiru's aura, he reached for his saber rather than surrendering, and he later rejected the Patrol Hall Master's offer of protected cultivation because he believes life-or-death demon battles are necessary for his growth. 15 36

Despite his reputation, Li is uncomfortable with public praise and formal gatherings. He often responds with dry humor, avoids taking sole credit for group victories, and argues that every person who contributes against demons is a hero. 35 40 44

Li can be blunt and opportunistic, such as searching Pure Land Temple's Scripture Repository for techniques, but he also keeps promises and aids people in danger. He chose to help Jingshan, escorted him from the temple, and gave Wang Debiao detailed cultivation notes before leaving Ning'an. 18 21 22 14
