In a rain-drenched alley after a storm, Lin Chuan is sent back to the most humiliating turning point of his destiny. His ex-girlfriend Su Yao sneers, "A loser is always a loser." The school bully Da Xiong swings his fist in intimidation, "Kneel down and call me daddy!" But this time, the martial arts system in his mind activates with a roar, and memories of perishing in a sea of flames in his past life flood back. He chooses the boxing technique Rock-Shattering Strike, shattering bones with a single punch, and asks calmly, "Just now, who did you say should kneel?" The system main quest updates: head to the city library within 72 hours to acquire the Taixuan Scripture and unlock the path of martial arts advancement. Failure will result in the system unbinding and the recurrence of soul trauma. In his past life, he lived a cowardly half-life, his mother fell seriously ill from overwork, and he perished in a sea of flames.
