In the Second Generation of the Trench, He Changed To the Ruanfan Script - Chapter 45:

What happens when a scientist from a futuristic world reincarnates in a World of Magic and Knights? An awesome MC is what happens! A scientist’s goal is to explore the secrets of the universe, and this is exactly what Leylin sets out to do when he is reincarnated.

In a land divided into the Light and Dark Magi, the weak can either be cattle or disposable slaves. Only the strong can determine their lives, and only they have the luxury for virtue. Yet strength is only a tool for Leylin, like any other. His goal, in the end, is his own.

Are you running away after getting me excited? Let’s see what kind of ending you want today.

Since you all asked for a wife chasing crack, then let’s perseverate to the end. I’m not crazy, you are the one who is crazy. This is probably a crack but still gentle gong and a shou fighting against the crack story. Lighthearted! Comedy! No brain cells will be lost!

I never asked to be a part of werewolf society - or this world.Every day that passes, the mating bond between my protector and I threatens to occur, once and for all. To consume me entirely... and lock my path with this world on the brink, even when I still think of home.⧖ ⧖ ⧖One minute I was Citra Lomdi - a Princess to a kingdom of silk and secrets in a whole other place.
