Raised in an orphanage since childhood, Ye Wudao is falsely framed by the Haicheng Ye family for a fatal hit-and-run accident and sentenced to fifteen years in prison. The moment he enters prison, he accidentally activates the Martial Dao Self-Improvement System, allowing his cultivation techniques and martial skills to autonomously practice through stimuli and grow rapidly stronger. Assigned to Cell Block Number One, reserved exclusively for martial artists, he befriends three fallen martial arts masters—Qin Shuang, Hu Feiren, and Zhang Kuangxue—and takes them as his teachers. Within the monster rift space connected to the prison, Ye Wudao relies on the system and his heaven-defying martial physique to hunt monsters, accumulate sentence-reduction points, and break through all the way from a mortal to the Condensed Liquid Realm, steadily soaring in combat power.
