City of Sin - Book 1, Chapter 1

As Shin Youngwoo has had an unfortunate life and is now stuck carrying bricks on construction sites. He even had to do labor in the VR game, Satisfy!

One day every human on the world suddenly receives a mail claiming to enact the World Salvation Project. Half in doubt Kurosaki Shion, a diligent university student and loner, follows the mail’s instructions, becoming one of a million Demon Kings governing his very own Domain in the new world.

*** This is a post-apocalyptic story containing many fantasy elements. It is a somewhat dark tale following Shion as he grows while aiming for the unification of the all too sudden new world. It has many game-elements bolstered by strategical thinking while at the same time providing funny moments and romantic encounters.

Lin Qingge’s body was pathetically weak, so weak that just taking a few steps would make him gasp for breath. His own family treated him like he didn’t exist. His birth mother died when he was young and his father promptly remarried and knocked his stepmom up. His father didn’t like him, his stepmom looked askance at him and his step siblings coveted his position. Who told him to be the lawful eldest with inheritance rights?

When Lin Qingge was eighteen he came out of the closet, creating a huge rift between him and his family. It was all for that guy, Liu Yang. He’d whispered sweet nothings in his ear, saying things like he’d protect him and bs like that. Lin Qingge’s old man blew his top when he found out and promptly disowned him. That didn’t matter to Lin Qingge, he had Liu Yang afterall. He fully believed in that guys words and goodwill.

If only he wasn’t so stupid…

Ultimately Liu Yang was like a vampire sucking his wealth dry, leaving a husk behind. After pushing Liu Yang to a high position, Lin Qingge finally collapsed in his apartment. It was a sad sorry sight. Closing his eyes, he knew this was the end of him. Who knew he would wake up instead in a different time and a different place?

Eh? What’s this? Well fine! This time I’m gonna hug that brother’s thigh real tight and never let go!

- Description from Novelupdates

Skyfire Avenue is a street that is 2048 meters long. There are 168 stores here, and each of the store owners is an extremely powerful adept. The Avenue does not permit any vehicles or any robots to pass through it, much less mecha. Even the patrolling police must move about on foot. This is because this is a street for pedestrians, a lane for nobles, hidden away within this high technology world. Lan Jue, the greatest of the mercenaries, code-named ‘Zeus’, has secluded himself here in Skyfire Avenue after the death of his wife. The name of his shop is “Zeus’ Jewelry Store”, and here in Skyfire Avenue, he has been given the title, Jewel Master.
