Realm of Monsters - Chapter 621: Celebration Part 1

Accidentally selected by a very H law of heaven and earth, in order to reproduce the glory of the three thousand daughters of the royal ascension to sanctification again.

The protagonist takes a magic weapon-shaped little black house called Xinggong, shuttles through the heavens and the world, kidnapping, forcing, bewildering, and deceiving the feelings of beauties.

Think about it, is it very exciting and shameless to lie to the little beauty to go to KFC (open a room), then pack it and throw it into the small black room and take it away, and then change the world to continue the crime.

This is fiction, not reality! Therefore, the heroine must accept everything, the non-virgins are all supporting roles, and the deaths are very miserable! Not even a chance to be a meat toilet!

Seol Woon-hwi, the Blood Heaven’s Righteous Blade, rose to power, becoming second to none under the heavens, reigning just beneath the sky itself.Yet, at the height of absolute power, he finds himself returned to his past—back to his days as the scorned illegitimate child of the Everlasting Snow Palace.

Best of all, he was the same age as her, and he had a system with him to help.He knows the future and a system that lets him continuously get stronger by completing quests or long-term missions, as well as giving him the ability to copy abilities from others for himself. He will become invincible in the world of Avatar, even more so than the Avatar himself.
