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

The disturbance caused by the immortal encounter had completely dissipated. Life in Peace County was as peaceful as ever, except for a few men who rushed into the mountains and never came back.

Jiang Ming's life was also fulfilling. Every day, he practiced martial arts, drank wine, and then went to the city for some entertainment. He lived a relaxed and happy life.

However, even if the immortal was suspected to be dead, Jiang Ming did not intend to go to the forbidden zone to explore anything. Who knew what other it held? At least, he had to wait until he became a Grandmaster before he went to explore that zone.

According to Yu Yan's report, the immortal's body had shattered completely after using a power that surpassed a Grandmaster's. It seemed that there was some strange rule in this world that forbade the existence of beings above the Grandmaster level.

Only after becoming a Grandmaster would he have the capital to explore all the secret places.
