A math genius transmigrates into the body of a village thug, repairs swords with formulas, and turns the cultivation world upside down with his silver tongue!
Ye Qingyu binds himself to a Chaos Jade Token, and must solve math problems to cultivate:
✅ Solve the Swordsmanship Art correctly = fly on a sword
❌ Solve the Swordsmanship Art incorrectly = split on a sword (earning the nickname “Split-Leg Sword Immortal”)
The ironclad rule of cultivation: those who fall in love forge a Sword of Emotional Tribulation. They must either sever their feelings and prove the Dao through the sword (BE), or enter the Dao through love (HE).
Ye Qingyu chooses a third path: he goes head-to-head with Ye Hongyu, the Demon Sect's Holy Maiden:
▶ While fighting over spirit herbs, they tumble off a cliff, and his Sword of Emotional Tribulation awakens as both a Sword of Wanton Pleasure and a Sword of Severed Feelings
▶ At a Dao debate, he breaks a demonic technique with a square-dance routine and is branded “a sword thug who brings ruin to the nation”
▶ As they stab each other in the Demon Palace, they trade barbs: “Your sword is too slow!” “Then stop dodging!”
Others cultivate immortality through sudden enlightenment. I solve linear equations in two variables.
Others sever their feelings to prove the Dao. I insist on marrying the Demon Sect's Holy Maiden with my Sword of Emotional Tribulation in hand!
