PS. Cover not mine, I just found it on google.

The moment the little tyrant of the nobles, Roel Ascart, saw his stepsister, he recalled his memories. He realized that he was in the world of a gal game he played in his previous life. To make things worse, he was the greatest villain in the common route of the game!

“I’ll be killed by the main character and the four capture targets ten years from now. Is there still any hope for me?”

Just thinking about the fearsome glints of those sharp swords those beautiful capture targets held in their hands, Roel couldn’t help but tremble in fear.

Till a voice finally sounded in his head.

【Welcome to the House Resurgence System】

After his soul transmigrated into the world of Teyvat, Luo Qing was selected to become the new Trainee Fatui Harbinger, and he was about to be sent to Liyue on a diplomatic mission (to cause chaos). To his surprise, he awakened a “Frustration Value Collection System” — as long as he frustrated others, he could collect frustration points, which he could use to participate in a lottery.As he stared at the list of items in the lottery interface, Luo Qing fell deep in thought:“Spirit Speech: Time Zero,” “Multi-Shadow Clone Technique,” “Thunder Breathing Style,” “Golden Experience Requiem,” “Railgun,” “Gomu Gomu no Mi...”Why on earth were these things appearing in the world of Teyvat?!Given the notorious reputation of a Harbinger, Luo Qing knew that if he didn’t grow strong, he was certainly doomed to a miserable end. Thus, his style became... increasingly abstract...---Years later, to prevent the infamous Fatui Harbinger, Luo Qing, from causing havoc everywhere, the people and political leaders of the Seven Nations united to issue a formal protest to Snezhnaya.In response, the Fatui in Snezhnaya issued an official statement:“This Harbinger is only a trainee. He has been dismissed.”

A youth crept on the ground in a snowy night. Hours ago, his tendons were cut because the girl he liked plotted against him. A mysterious middle-aged man saved him, and a pair of gigantic purple pupils appeared in the sky. Under the thunders and lights, the rare Demon Pupils and Sacred Body were awakened. That was what he should have been.

However, in this world, strength was the only way to support a man to live. His adoptive father died for covering him. His true love fell into the abyss for saving him. He wanted to rise up, to take revenge, and to protect the ones he cared about.

Occasionally did a strange figure confuse him. Behind the huge demon pupils, he often saw a thirty thousand feet tall black figure. What was it? Who was that?

It was said that the ultimate bloodline of the universe was the Primal Chaos Divine Body. It was a divine existence which could break the heavens and annihilate the world in a second. However, this sort of divine body had been extinct ten thousand years ago.

Could it be that apart from the Sacred Body, there was another body in him?
