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.

I am Ye Qing. Lucky I found a [Monster Factory] application.

This bunch of super strong monsters are individually comparable to over 100 human beings, and they bring all kinds of skills!

Efficiency? With the skill processing speed +300, you still want to compete?

Precision? *cough, cough* Bring me that legendary dial caliper, let’s show them what absolute precision really mean.

Ye Qing: When, us, men want to be successful, we pull out our wallets.

Monsters: Don’t play those malice games with us. The creation of ultimate machinery is our love and life. These impenetrable bodies are our tools of the trade.

A 20 meter tall, overly buffed, savage looking monsters hold on to a ultimate cutting machine and yelled at the sky: “I am not targeting anyone specifically! Rather I am telling you all that, everything, in front of me and my tools are, nothing, but TRASH!”
