Cao Yu transmigrates into a world of mixed martial arts and becomes an utterly ordinary novice Taoist sweeping the back mountain of Wudang. He's also Zhang Sanfeng's nominal junior brother.
In this high-martial world, where Grandmasters are everywhere and Earthly Immortals are a dime a dozen, Cao Yu had planned to keep his head down and cultivate immortality.
Until one day, Yihua Palace Master Yaoyue, pursued by her enemies, falls into the vegetable garden on the back mountain, covered in blood.
Seeing several of his spirit herbs destroyed, Cao Yu flies into a rage.
"My thousand-year-old vermilion fruit!"
With a flick of his hand, a palm-thunderbolt instantly obliterates a dozen top assassins!
Yaoyue's worldview crumbles. "W-what kind of martial art is this?!"
Cao Yu sneers. "Martial arts? I'm cultivating immortality!"
From then on, the back mountain of Wudang gains a fire-tending maid named Yaoyue, a laundry maid named Wanwan, a wood-chopping maid named Dongfang Bubai...
When the six major sects besiege Wudang and Zhang Sanfeng falls in battle, covered in blood,
a sword beam shoots into the sky from the forbidden grounds on the back mountain, slaying a hundred thousand soldiers from a hundred miles away!
Zhang Sanfeng is stunned. "Junior Brother, you call that martial arts?!"
