A loner boy, who’s always loved escaping into his RPG world, suddenly finds himself living as one of his game characters. But instead of becoming his favored fighter, he’s in the body of his second avatar—a support mage! Though he’s used to playing both roles, being the mage in real life is a whole new challenge. Now he must rely on his knowledge and skills to navigate this unfamiliar reality and survive as the game's “support.”

When Jiang Ming woke up, he possessed the power of immortality.

Facing the cruel and dangerous world of cultivating immortals, Jiang Ming realized his own path of cultivation.

That is, only practicing forbidden techniques!

Blood-burning knife technique, one year of life lost for each cut… Eat me ten times first!

A holy body for a hundred eons, three levels for one day…refined to one hundred thousand levels!

The Heavenly Reaper Technique, if you use it, you will be backlashed by the destiny… Let me first calculate the color of the saint’s clothes tomorrow.

To break the delusion, you need to look directly at the indescribable things…

Birth and death, being scoured by the secluded capital Huangquan every day…

Practicing and practicing… Jiang Ming discovered that his forbidden technique was already invincible in the world!
