Isekai Maou to Shoukan Shoujo no Dorei Majutsu - Volume 10 Chapter 1 part5-6

Twelve years ago, an old beggar found an abandoned baby and took him as his own son, naming him Xu Han. But when his foster father dies, Xu Han finds himself in a training camp with dozens of other kids, though what they’re training for remains a mystery. It’s here that he meets his best friend, Liu Sheng, and life is good for a while — regular hot meals and a safe place to stay. But kids keep being taken and not coming back, and eventually, Xu Han and Liu Sheng find themselves left in the woods at night, where they discover what’s happened to the kids who disappeared before them — they’ve been turned into zombies! Can the pair destroy the zombies and survive the night, or will they be the newest victims of this twisted conspiracy?

Chu Li was a particle physicist until a freak accident took his life and transmigrated him to a parallel universe – one where he wakes up with inexplicable abilities and finds himself in the running for a job in the imperial palace.

This is a story of heroic adventures, cunning strategies and romantic tales. How will our MC thrive in a world completely strange to him? Where will his ambitions and abilities take him in the palace?

Liu Qing resigned.

He wrote on the reasons for his resignation:

“I’m going to inherit hundreds of millions of properties.”

- Description from novelbuddy

There are a total of seven sins, and a revelation is made to a young man named Alex that he is destined to become a demon lord, more especially a demon lord of sin called LUST.

It's not like he can change that and because he always knew something about himself was different—not in a physical sense, well, maybe a little—and not in a mental sense—but rather because he is thrown into a demonic war that compels him to accept his new reality.

He was only aware of a difference in himself. Relating to him and the ladies who are drawn to him... Well, it was more or less like he was a magnet in front of all the girls, and all the girls were drawn to him like a metal.
