I Will Become the Demon Emperor at the Beginning and the Universe Will Be Decided by Me.

My name is Cheng Yu, I was originally a university history teacher, a bit of an otaku! Unexpectedly, he accidentally went into shock after saving someone, but traveled through the chaos and became the 108th son of the demon Bo Xun! Bo Xun changed Chen Yu's name to Chen Shiba and gave Chen Yu a system of rules! He also told Chen Yu that the Heavenly Demon Clan exists to maintain the balance of the universe and eliminate weak races. Chen Yu was required to complete the tasks taught by the system within a year and defeat himself as the Heavenly Demon King. Otherwise, like the 107 brothers before him, his soul would be sealed forever, locked up in a container and become a living dead! Chen Yu received the blessing of the invincible system, obtained invincible magic weapons and techniques, wiped out clans and planets one after another, and became the overlord of the universe, the Great Demon King!
