The Mage of Eternity - Chapter 874 - : Humanoid Transformation

Humanity was living peacefully on Earth for millions and millions of years until the day unknown monsters from beyond space invaded them.

When humans were about to disappear, some people with abilities came out to the light and shared their knowledge and powers with the world, and together, they managed to push back the invaders during a terrible war that had lasted for years.

This war had created many orphans, and among them, Kye had lost everything, even his parents. And the only thing he received from their death was a pale-looking necklace.

However, once the necklace finally activated, a system was given to him, and his life changed completely.

The system gave him quests to do, and Kye complied. He was getting stronger every time he achieved them, until the day it gave him a weird quest.

[You have one day to kill the one who had sinned. If you do not kill, you will die.]

After three years of hidden marriage, she has always been well-behaved and obedient, and she never made a fuss when she saw him having an affair with others.

He asked in a cold voice, “Why, do you have someone you like?”

She smiled lightly: “Yes, if you don’t admit that I am your wife, someone will always admit that I am his lover.”

Later, she was recognized by the Xie family and became the daughter of the Xie family that even he could not afford.

Seeing her doing well among men, Gu Jinmo realized that the love roots she had planted in his heart during those three years had already grown into towering trees, imprisoning him for the rest of his life.
