The Tech Genius Is Forced to Cultivate Immortality

In my seventh year after transmigrating into the world of immortal cultivation, I made a nuclear bomb by hand and wiped out the demonic sect’s number one clan.

I was just about to use interstellar weapons to unite the cultivation world when the System suddenly issued a warning: [High-dimensional entity intervention detected]

The Immortal Alliance’s old ancestor trembled as he offered up the Alliance Leader’s token. “Please ascend! The upper realm says it’ll collapse if you keep bombing it.”

I gazed at the crack in the Gate of the Immortal Realm above and fell into deep thought

Should I try using a planet-destroying cannon to survive the tribulation?
