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

After giving the last female immortal cultivator a quick death, Jiang Ming quickly left the valley and continued to advance into the depths of the snowfield.

"Those two were quite honest. They both gave the same information," Jiang Ming muttered to himself.

Jiang Ming now had a deeper understanding of the world of immortal cultivation outside the Red Pine Snowfield.

Outside the snowfield was a vast area called the Litfire Region. Although it was only a remote corner of the Feather Kingdom, according to those two, the area was ten times as big as the Cloud Empire. Almost all mortals had never left the Litfire Region in their entire lives.

"The four major immortal cultivation forces in the Litfire Region all have early-stage core formation cultivators. The first three are all immortal cultivation sects with strict rules. Only Xiaoqian Mountain is an exception. On the surface, there are no mandatory restrictions on the cultivators living there."
