Invincible Emperor: I Returned from Practicing in a Dream!

Ye Xuan had a dream! In the dream, he was the giant of hell and the supreme ghost emperor! He once slayed through the underworld and broke the cycle of reincarnation. He had hundreds of millions of sinister soldiers and ghosts under his command. He slaughtered all realms and turned the heavens upside down with a wave of his hand. I originally thought it was just a dream, but I didn't expect that because I transferred to another school, I encountered a headless female ghost in the rented house who was asking for her life. Ever since, Ye Xuan discovered that it seemed that it was not a dream! Zhuang Zhou dreamed of butterflies, and butterflies dreamed of Zhuang Zhou. Was that a dream, or is it now... A dream? ...
