Su Fu traveled to the world of immortals, but he was not living comfortably until one day he suddenly got a system...

"Master Su's cultivation is immeasurable. He can kill people invisibly with just a hidden weapon!" Such rumors spread in the world of cultivation. Su Fu touched the 98k in his hand guiltily.

"The disciples of the Black Iron Sect have noble morals and a firm heart for the Tao!" Many powerful people praised. "The system teaches well." Su Fu said.
