MTL - Rebirth: National Crown Prince - Chapter 23 chuan

Keith, a regular office worker from Earth, suddenly transmigrates to the world of the novel he had been reading for the past decade. The new world, which was also called Earth, was slightly different. People with various powers existed who were called awakeners, making this world comparatively dangerous and also mysterious. While he was thrown into the novel’s world, he was also given a mystical ability to grant systems to other people. Armed with his special ability, he slowly climbs up the power ladder by taking “taxes” from the people he would give systems to. The only question that remained, was what would a realistic normal man, when faced with a similar minded protagonist, do when their goals opposed each other.

A genius idiot born from an incestual marriage!

A young man with triple identities of worker, murderer, and university student!

Cadillacs and Dinosaurs, Sangokushi, KOF, Knights of the Round, Shadow Force, Street Fighter…

Each one of the arcade games you are familiar with has already been changed into a prerequisite for survival!

Slaughtering Shiranui Mai with Ya Otome, Jigoku Gokuraku Otoshi to kill Li Dian. There is only what hasn’t been thought of, there isn’t anything that can’t be thought of!

On an unknown day, when you walk down the stairs, you may accidentally walk into this —— arcade nightmare!

A fourth chance at life. The last chance.Zarek remembered when he first experienced the Godsfall Apocalypse. Those tears of red and sparkling rouge that split the skies, opening up one dangerous realm after another.That feeling of helplessness had been palpable, heavy... suffocating. It hung above his head like a guillotine, an edge graced by death's kiss...He grinned at it.One last ride, no Talents left on his stat screen, and nothing but a dull machete and his girl by his side. What was a better thrill than that?How could he possibly fail a fourth time?Unfortunately, there were others. Other Rebirthers. Some that might have been on their last attempt just like him, or some that still had more to give to this cruel world.None of it mattered, though. He had planned everything out meticulously, each life playing its own role.He would come out on top this time. How could he not?He was Zarek Ashborn.

I became the childhood friend of the protagonist in a novel. The childhood friend who died from taking drugs.
