The Magic Power Is Great, You Tell Me This Is the World of Cultivating Immortals?

The way of humanity is vague, but the way of immortality is vast. Song Zian traveled to a strange world and activated the system. Then he was locked up in a small dark room by the system for thirty years, where he learned various techniques and secrets. In the end, the magical power was achieved, and he became proficient in both literature and martial arts. I thought that as soon as I came out of the mountain, I would be invincible in the world, and I would be invincible in the world. I didn't expect that this fucking world turned out to be a world of immortals and heroes. I was so depressed... He didn't know how to cultivate immortality, so he decided to become a handyman disciple of Xuanjian Sect in order to survive and live out the rest of his life in peace. Seeing the envious looks of the big guys in the sect, Song Zian felt very strange, why are you all looking at me? I'm just a martial arts master who doesn't know how to cultivate immortality. As everyone knows, even in the world of immortals, Song Zian is still invincible. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
