MTL - I Can Rewind - Chapter 186 Poussinger experiment

“He is the entertainment king who is in charge of everything. Been single for years, he had zero scandal. One day, a woman and a girl turned his life upside down.

The little cutie held him tight, not letting go. “”Handsome uncle, you look very much like the daddy I have lost for many years!”” Huo Yunshen felt depressed. “Me? Daddy?!”

The little cutie proudly pulled her mommy over, “”Mommy, I have found a long-term meal ticket for you, handsome and gullible.””

Xu Xiyan smiled at the elegant man.

Recalling the accident five years ago, his face sank. “”How dare you steal my DNA?””

She laughed. “”Not steal, just borrow!”” The man took her in his arms and warned in a dangerous tone, “”Woman, should I get what’s mine back, with interest?””

She stood on her toes. “”Yeah, how about another baby?”””

- Description from Novelupdates

A 29 year old civil employment exam student wakes up in a blank white room and meets a baby angel. This baby angel informs him that he died in his sleep due to heart disease like his father and grandfather. Remembering his mom and their last conversation he says that he will take on a series of life and death tests that the baby angel offers him. From this point on he must put his life on the line and fight in the stage called ‘Arena’. And Every time he clears a test he will gain abilities and weapons to increase his strength. All to clear the tests and get his life back. This is his story of his fights in the ‘Arena’.

This story is centered around the man named Yi Ji-Hyuk, who has spent 1000 years in a Medieval Western fantasy-like world before returning back to the modern-day Earth. When he returns, he finds that his home is facing monster threats, and that humans with superpowers have appeared to protect the innocent people of Earth.

Following a brutal and tortured death, a former assassin, known only by his codename Kuro, is given the opportunity to reincarnate in another world, a world with magic and monsters. Armed with an unrivaled healing factor and an inhumane pain threshold, Kuro opts to go for a reckless direct approach in this world instead of a stealthy and cautious one, and as a result, slowly gains attention bit by bit.

Having previously been a loner in his old life, he interacts and befriends people for the first time in his existence, however, his blunt nature also sees him making just as many enemies, both big and small. By combining his old assassin skills with the magic powers of this world, along with his high resistance to pain and rapid regeneration, he doesn't take long to establish himself as a formidable force in this world.

Initially, Kuro only faces minor threats, like weaker monsters and bandits. But before too long, the threats slowly but surely become more and more severe…from Zombies to a bloodthirsty empire to Vampires and Demons, and even divine beings…however, as the enemies he faces grow stronger, so does Kuro, gaining rare powers that have never or rarely ever been seen in this world…
