Leveling with the Gods - Chapter 4

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.

DING![Ist Skill Devour Successful]______“They say a man's skills are honed over a lifetime, but what if he could devour them all in an instant?”Ryuen Takeru, a skilled, retired assassin, decides to pursue a better job that would keep him away from the dark life he once led.However, after a while, that peace was shattered when an unexpected train ride derailed reality itself, throwing him into a world and a life he had always hated.A world teetering on the brink of ruin, destroyed by an apocalypse as a result of the unending war between multiple races.Unfortunately, the post-apocalypse had already begun.Ryuen finds himself captured, exchanged, and made to serve kings of different nations.Yet fate had more in store for him.A devastating twist, capable of destroying or elevating him—the one thing he had overlooked as normal until the moment he was informed.A curse.Possible reincarnation?[Skill Devourer Activated: Plunder, Consume, Adapt, Evolve.]Nevertheless, for everything given, something must be taken—or perhaps sacrificed.

Waking up, Kim Hajin finds himself in a familiar world but an unfamiliar body.

The world’s top ten conglomerates had joined forces to create a programme where the crew had quietly evacuated all the people from a city, leaving behind only Raymond and his family, who were kept in the dark. Their purpose was to see this child, who had emerged from the slums of America, get humiliated.
