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.

Qi Refinement Realm cultivators could only refine magical tools and weapons up to the middle grade.

Everything above the middle grade could only be refined by Foundation Establishment Realm cultivators and above. However, the price of high-grade magical tools was frighteningly high, and they were very rare. More than half of the Foundation Establishment Realm cultivators only used middle-grade magical tools.
