Fellow Taoist, Please Stay and Let Me Lend You a Magic Weapon!

Lu Xiaochuan woke up and became a low-level minion of the Demon Sect. He practiced Qi and his magic weapon was an unheard-of wordless heavenly book. What's even worse is that his soul was manipulated and he was forced to do an undercover mission with a mortality rate of 99%. Just when Lu Xiaochuan thought that the start was going to be "heroic", the old monster of 100,000 years ago, the old monster swallowing the sky, woke up in ruins: Boy! Want to survive? Want to become stronger? The ancestor teaches you a trick - grab!
