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.

CatABoo

Jiang Ming's heart moved, and he pretended to know nothing and cooperated. "Why?"

The black sword hurriedly explained, "The fog here can replenish my energy. It's a rare and wondrous thing. Not only can it assist in martial arts cultivation, but it also has a terrifying weakening effect on immortal cultivators. If they're not a Foundation Establishment Realm martial artist, even a Golden Core Realm cultivator will suffer if they come into contact with it!"

"Oh? I tried to collect it before, but I didn't succeed!" Jiang Ming said lightly. However, he was surprised. Previously, he only found that this fog could weaken immortal cultivators. However, he had not found out that it had an auxiliary effect on martial artists.
