World Teacher – Other World Style Education & Agent - Chapter 120 - The Center of Everything

Within the Huang Realm, a world where the era of divinities has ended and the era of immortals is nearing its waning years, exists the Buzhou Immortal Sect. And within the Buzhou Immortal Sect on Jade Peak was a disciple of the sect, Xi Tianyi. He was of noble birth, the only child of the Sword Empress who reigned invincible.

But the truth was that Xi Tianyi, was originally an ordinary mortal from Earth who suddenly woke up one day as in another world filled with immortals and demons. Under heavy pressure, knowing that his life is at stake to whoever is strongest, Xi Tianyi quietly cultivates in hopes of one day fearing no one and discovering the circumstances of his transmigration. But…

«You bastard, you stole my fiance!» Said a former genius who had lost all his cultivation.

«Bastard, pay with your life for the death of my entire clan!» Said a cultivator with blood leaking from his hatred filled eyes.

«What the hell?! I’ve been cooped up cultivating quietly so why are you guys suddenly finding trouble with me?! Besides, I’m only ten!» Cried out Tianyi in disbelief.

«Fine, if you want to make me your cannon fodder, I’ll step on your corpses for my ascension!»

The devil would love you only in his own way: “Remember, don’t look at me, don’t hold me, and don’t kiss me! Turn your face away, as long as you lie down obediently and quietly! ” Just lie down obediently? What did he take her for? An inflatable wife?

By the way, it wouldn't appear NTR or some bullshit harem of courtships. MC of course will have harem but not for cliches.

King Grey has unrivaled strength, wealth, and prestige in a world governed by martial ability. However, solitude lingers closely behind those with great power. Beneath the glamorous exterior of a powerful king lurks the shell of man, devoid of purpose and will. 

Reincarnated into a new world filled with magic and monsters, the king has a second chance to relive his life. Correcting the mistakes of his past will not be his only challenge, however. Underneath the peace and prosperity of the new world is an undercurrent threatening to destroy everything he has worked for, questioning his role and reason for being born again.
