Vast Sky Drizzle

When Jiang Ming woke up in a strange world, he learned he had obtained immortality. In the dangerous and ruthless world of cultivation, he was determined to carve his unique path. Taking advantage of his immortality, he vowed to learn forbidden skills that would normally eat away at the user’s life. 
As he continued on his path, Jiang Ming realized that with his forbidden skills, he could become the strongest. 

As An Immortal, I Only Learn Forbidden Skills

CatABoo

Rao Wuqing was a cultivator with great perseverance. An ordinary person would definitely not be willing to destroy their cultivation.

However, Jiang Ming only said a few words. "You're in charge of destroying your base and cultivating again. I'm in charge of refining pills and providing your cultivation technique."

Then, Rao Wuqing started destroying his cultivation base.

Not far away, Wu Hen, Ying Sha, and Huai Mei looked at this scene with bewildered expressions.

"Ning Caichen isn't trying to trick Rao Wuqing, is he? What kind of amazing pill can heal the cultivation injuries of a cultivator who was half a step into the Nascent Soul Realm? Moreover, Rao Wuqing has suffered injuries for nearly a hundred years and was destined to never recover. If he loses his cultivation base, Rao Wuqing will probably fall into the mortal world."
