This Cultivation Technique Is Seriously Improper!

Qin Yan has a pure yang constitution: he spontaneously combusts while walking down the road and breathes fire when angered. People call him “a walking city-incinerating furnace,” and he’s just one sneeze away from exploding and dying.

Ling Shuang has a pure yin constitution: a handshake can give you frostbite, and a breath from her can freeze the air. People curse her as “a mobile icy tomb,” and she’s only a breeze away from turning into solid ice.

They are opposites that heaven and earth should never have allowed to meet, but after an accident blew up a furnace at an apothecary, they became sworn enemies. Worse, a sky-high bill for damages forced them into a “doomed partnership.”

To stay alive, they have no choice but to practice the orthodox cultivators’ despised manual, The True Art of Yin-Yang Union.

Who knew its first chapter would call for “embracing to exchange energy,” its middle section would include “illustrated positions,” and its final volume would promise “a shared bath in a spirit spring”...?

Before long, blowing up furnaces becomes part of daily life, while getting frozen into ice sculptures and roasted to a crisp take turns happening. Even the notes left by their predecessors are full of cultivation tips that are “so funny you’ll die laughing.”

“Qin Yan! Burn my hair with your yang energy again and I’ll freeze you in an ice cellar like a popsicle!”

“Ling Shuang! Freeze my dantian with your yin energy again and I’ll toss you into a volcano like an ice lolly!”

From sabotaging each other to embracing in desperate moments, from unlocking new positions to understanding each other’s hearts, this pair of “fire-and-ice enemies” turns the shameless technique everyone condemns into a chaos-shaping Great Dao, amid laughter and flirtation.

When villains try to rip out the source of yin and yang and the world teeters on the brink of collapse, they finally understand:

The most extreme constitutions can spark the most improper romance and forge the most upright legend.

Years later, an apothecary hangs a sign: “We treat yin-yang imbalance and cultivation mishaps. The married owners demonstrate the treatments themselves, with excellent results. Side effect: you might laugh yourself to death.”
