From Idler to Tech Tycoon: Earth - Chapter 28: Vector Core Completed

Shao Qing’s only regret in life is that she blindly fell in love with a worthless man. She gave up everything for him, but in exchange was run over by his conniving mistress when she was close to her delivery date. Fortunately, Heaven left her a way. Crimson rain fell from the sky, the end of the world arrived, she resurrected in the morgue and gave birth to a little monster. Turning into a half human, half zombie freak; her son neither human, nor monster; they have no other choice but to rely on zombies’ crystal nuclei to develop their special abilities and continue living. This debt, she’ll definitely repay that cheating couple!

Ye Fei is a poor, down on his luck kitchen hand and could not pay his rent on time. After desperately dodging the landlady with some rash promises, he ducked into his room where he was electrocuted while turning on the lights.

Miraculously, he did not die. Instead, a strange [System] appeared in his head ordering him to do strange things like registering with a broadcasting network and performing strange feats in front of a camera!

Oh, that new laptop? That high tech camera? And those ingredients that appeared in his room?

Somehow all these were provided by [System], and and just appeared in his shabby little room! Just what is going on?

*Gurgle*

Whatever, Ye Fei is too hungry to care, let’s just do whatever and hope for the best!

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.
