MTL - Mecha and Knife - Chapter 810 How dare you?

The future of the world and the direction of time possess infinite possibilities. Even the same event may lead to two completely opposite outcomes due to a millisecond deviation in completion time.

I have led the Evolutionary Deluge, causing species worldwide to evolve and creating a splendid era of warriors. I have also allowed the invasion of evil gods, bringing those indescribable ancient dominators to the mortal world, instantly corrupting the Earth with evil beings.

In the infinite space-time, there are a million possibilities. I have witnessed the divinization of machinery and have seen the revival of myths. Humans call me: The Creator of Everything, The Eternal Supreme God, The Cause of All Results, The Origin of Everything.

But.. I prefer to call myself a humble observer.

CEO Leng Li: The sky has finally cooled down. It’s time for that person who bullied my sister to go bankrupt.

*

Jie Ao –xianzun (officer of Emperor Jie): The emperor is not allowing me to marry my junior sister? Good! Then, both of us are going to elope.

*

Overbearing Regent: This is my little princess! What do you mean by thousand pounds of gold and precious nobles? All of you kneel down to her!

*

Tong Su only wanted to complete her task of eradicating the scum male in order to get a chance to exact her own vengeance. However, this big BOSS, why do your eyes show such emotion towards me?

Important note: Sweet pet, oppressive slag, fake brother and sister, not blood related!
