Ruins stretched across the landscape in the apocalypse after the nuclear war.

If you accidentally survived on the wasteland, then you must be ready to face the endless hunger, ceaseless dangers, the mad zombies at night, and the peculiar mutant creatures that are the aftermaths of the constant radiation.

But for Jiang Chen, this place was heaven.

Mansions stood tall, luxurious cars parked on the street, high tech products and gold abandoned everywhere.

What? You were the president of a game development company before the war? You were responsible for the development of the 3D virtual reality online multiplayer game? Well, that’s great, why don’t you come work for me. The salary is two pieces of bread a day.

iPhone? Ultra thin design? Don’t you see that the phone I invented are thinner than condoms?

Aircraft carrier? Fighter jets? Oh, I have those things as well, but they are designed for space combat.

Watch the story of Jiang Chen, who possessed the ability to travel through space and time, as he witness the creation of an empire stretched across space and time..

- Description from Novelupdates

The tale of Oliver.
An orphan boy from a Mine, in 19th century Europe, filled with Magic.

After being given up on by his family because his dantian was destroyed, Soh Woonhwi was kidnapped by the Blood Cult and lived as a third-rate spy.

One day, he died while being used to find a legendary sword immortal’s secret records. However, he returned to the day he was kidnapped ten years ago and obtained a mysterious ability that allowed him to hear the voice of swords.

Noah Brown had a gift for fighting. Unfortunately punching things didn't pay the bills, at least until he died and an Eldritch god found his soul. The encounter led him to a new world, summoned by bloody cultists, with nothing but the shirt on his back, and a strange item in his system menu.

[???] : A source of infinite potential.

Perhaps he'd finally get to put his gifts to good use.
