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

Xie Qianling opened her mouth wide, and her body grew gigantic.

Jiang Ming was impressed but he did not forget to take countermeasures. He went forward and sent continuous waves of spiritual energy.

A few of Xie Qianling's teeth were broken, and her blood splattered to the ground.

She immediately went back to normal and covered her mouth.

Xie Qianling had learned her lesson.

She could not grow bigger. Once she grew bigger, her teeth would be broken!

Jiang Ming sized Xie Qianling up and rubbed his chin.

She clearly knew her own strength.

Jiang Ming felt that Xie Qianling would probably continue to plot against him, so he secretly defended himself against her, but he still agreed to her request on the surface.

"Xie Zhizhi, you should go back to the mermaids."
