Teacher, It's Level 10,000, Don't Lie Down!

[Invincible] Sikong Xing traveled through time and unfortunately fell into the battlefield of ancient gods and demons, but unexpectedly absorbed all the remnant souls of gods and demons. His level instantly broke through to 10,000, and integrated the memories of all ancient gods and demons. God-level skills, god-level formations, god-level alchemy, god-level weapon refining... He can destroy the world with just one move. He was invincible at the beginning, but he didn't show off or dominate. He stayed in a dilapidated cultivation school as an ordinary theory teacher. Hey, just for fun! "Ding! Congratulations to the host for awakening the super cultivation system..." "I am invincible, what use do you have? Just be a laborer for me!"
