Qin Feng transmigrates to another world and is betrayed by his childhood sweetheart.

Fortunately, he was rescued by a mysterious woman, and all he needed to do was become her disciple to activate the fate-changing system.

He thought it was an opportunity, but after becoming an apprentice, he discovered that the beautiful master who appeared out of nowhere was actually the rumored female demon who treated human life like dirt.

Besides him, there were also seven fairy senior sisters who were eyeing him covetously.

The eldest sister's legs are longer than her life;

Second Senior Sister's waist was as slender as a willow branch;

The third senior sister has large breasts and a mole;

Fourth Senior Sister's deadly sweet voice;

...

However, as they spent more time together, Qin Feng discovered that his seven senior sisters were not at all as cold and aloof as rumored; on the contrary, they were... excessively enthusiastic towards him.

Senior Sister: "Junior Brother, don't you think my legs are long, white, and straight?"

Second Senior Sister: "Junior Brother, come over tonight and give me a back massage."

Third Senior Sister: "Junior Brother, I've been experiencing chest pain lately. What do you think could be the cause?"

Fourth Senior Sister: "Junior Brother, why won't you look me in the eye? Do you think I'm going to eat you?"

...

Finally, even the cold-hearted female demon master became warm.

"Your senior sisters don't know their place, so to protect you... from now on you will sleep in my bedroom!"

Qin Feng: "???"

Years later, Qin Feng finally realized what was happening.

It turns out that his Heavenly Profound Yang Body is an invaluable tonic for sects that cultivate special techniques.

"Line up! Everyone who wants to increase their cultivation level, line up!"

Qin Feng was numb.
