Go into Immortality

The year the Lu family was exterminated, Lu Chen learned the only thing: in the world of immortality, the winner is the one who survives to the end. He has one more thing than others - the skill of swordsmanship. For every day of hidden cultivation, a sword energy accumulates in the Dantian. The longer you hold back, the more brutal your killing move will be. He originally wanted to wait until he got the golden elixir, but someone wouldn't let him. The moment all 108 sword energies were released, Xuantian Sect's mountain gate split into two halves.
