MTL - The Legendary Mechanic in Marvel Universe - Chapter 50 found it

Three years ago, to defeat the Demon God who was trying to destroy this world, thirteen Braves were summoned from another world. Each of them had varied ages and gender. Each of them was bestowed with cheat like powers not normal in this world.

“You will suffice.”Raizen heard those words the night something chose him to survive.He doesn't know what whispered inside his head. He doesn't know why. But ever since that night, his life hasn't been entirely his own. Something marked him.Now he walks a beautiful world built on even prettier lies, where Eon turns desperation into miracles, Luminite weapons twist the laws of what's possible and what's not, and where humanity has been fighting creatures of shadow - Nyxes - for as long as anyone can remember. Though sometimes, the cruelest of enemies aren't made of darkness at all...But Raizen is starting to realize: the monsters aren't the only things hunting him.Something primordial is watching. Waiting. Pulling strings he can't see.If he wants to survive, he needs to get stronger.If he wants answers, he must become someone even the nightmares fear....But to win?He may have to end anything in his path - and pray he doesn't give the whisper exactly what it wanted all along.

When Bai Mufan opened his eyes, he found that the whole world had changed!

The concept of men and women in this world is reversed, women are respected, it is normal for women to go out to earn money to support their families, and men even aim to become a househusband in life!

The most frightening thing is that Bai Mufan also found that there is an extra boyboy system in his brain, clamoring all day long to make him the world’s number one boyboy!

Bai Mufan was angry.

“Even if I, Bai Mufan, am ugly and can’t find a wife for the rest of my life, I definitely won’t be a badass!”
