A Practical Guide to Evil - Chapter Book 1 1: Knife

Yo, Hi! I’m Frank, I made a deal with a demon to pay me some money for receiving a guest for a few days every week.
I had no idea about what I have done.
On May 1st, Conan ‘the God of Death’ came to my house. I was forced to let him in and we get involved in a criminal case.
On May 8th, Bruce Wayne ‘Batman’ came to me. I was forced to follow him to fight crime.
On May 16th, Hannibal Lecter, The Silence of the Lambs, came to my home. I can only say that I really can’t stand my guests.

This is a world where technology and the supernatural exist. There are demonic beasts, wars between species, evolution, and danger everywhere. Fortunately, humans aged between 16 to 18 will have the chance to activate certain genes and become gene warriors.

Gene warriors will enter a wonderous World of Origination and begin their adventure there. They will seek treasure and copy extraordinary genes to gain wondrous strength, becoming the main power against danger.

Lu Yuan transmigrated to this world, bringing with him a cube that can evolve genes without limits.

I woke up with a start.

I have transmigrated, am handsome, and have the golden touch. I am going to win at this! Am I going to be the protagonist?!

I, Lu Yuan, am definitely going to become the pillar of the human race!

Luo Wencheng made a deal with a certain existence and went back in time to ten years ago, when he had just been released from prison, still young and healthy, not yet pushed to the breaking point by Luo Wenjun and not yet used by him as a prop to test drugs for profit until his tragic death.

This time he was going to trample Luo Wenjun underfoot.

The first priority was to steal Luo Wenjun’s future backer from him.

Jiang Mianmian time traveled.

Her father had an insidious scholar’s face but a sinister heart.
