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

Sikong Wuyuan did not understand. "Xie Zhizhi, I remember that those mermen were there when they called Jiang Ming the mermaid princess. Why are you asking?"

"Oh… I didn't notice Jiang Ming's situation," Xie Zhizhi said awkwardly. "All my attention was on Ling Yunxiao."

Jiang Ming wanted to roll his eyes.

Love truly made one blind and stupid!

"Ning Caichen," Xie Qianling said. "You have to be the mermaid princess."

This time, it was Jiang Ming's turn to be dumbfounded.

He did not want to be forced into such a mission.

Also, he did not seem to know the answer to his question.

Xie Qianling gave Jiang Ming an answer. "Ning Caichen, the mermen will only recognize the person with the jade seal as the mermaid princess. Previously, it was Xie Zhizhi, now it's you. Xie Zhizhi, you should be very happy, right? Without your mission as the princess, you can be with Ling Yunxiao."

Blind and Stupid!
