Chen Fan clutches the dilapidated martial arts school his grandfather left behind. With a qi-and-blood level of just 3 calories, he's the "good-for-nothing martial artist" everyone in the old district laughs at. The owner of the Fierce Tiger Martial Arts School shows up with his disciples to wreck the place, threatening to cripple Chen Fan if he doesn't move out within three days!
With nowhere else to turn, a cool beauty with a pale face suddenly appears in the attic. "I'll pay three months' rent in advance. In return, I'll keep your school safe."
Only when Chen Fan gets pointers while practicing his punches does he learn that his tenant is Su Qingyuan, the national martial arts champion who was framed three years ago and went into seclusion to recover!
"You're not a good-for-nothing. Your natural bone structure has been sealed." Su Qingyuan tosses him an ancient boxing manual. "I'll teach you martial arts, and you help clear my name."
And so begins the good-for-nothing's rise to power: the heroine personally teaches him how to generate force, while ancient alchemy sends his qi and blood soaring. The hero knocks challengers flying with one punch, claims treasures in secret realms to break the seal, and pushes his qi and blood past 100 calories!
Zhao Kun goes too far? Beat him down! Li Mao frames the heroine? Expose him in front of everyone and cripple his cultivation! The Wang family wants to monopolize resources? Subdue them with a single punch at the martial arts selection tournament!
When the dilapidated school hangs up a "Five-Star Martial Arts School" plaque, Chen Fan holds the complete copy of the "Vajra Fist" manual and looks at Su Qingyuan, now restored to her peak. "See you at the national tournament, Master!"
[Urban High Martial Arts + Good-for-Nothing's Rise + Deep Master-Disciple Bond + Secret Realm Adventures] So what if his qi and blood level is only 3 calories? With a retired female martial artist carrying him, he'll still cut through the martial arts world!
