I Alone Level-Up (Web Novel KR) - Chapter 4

Alex was an ordinary person with the dream of one day being transmigrated to a magical world.

But what he didn't expect is that he would be transmigrated to a world much more than that, a world he knew very well, but instead of being given a system that would empower him, he was given a system that allowed him to make games, and the more people played, the more powers he would get.

Tony Stark: I hate this! I can do in real life everything this Watch Dogs guy does, but why can't I stop playing?

Hulk: HULK HATES DARK SOULS!!! HULK SMASH DARK SOUS ARRRHHHHGGG!!!

Nick Fury: If any agent can't complete the Hitman game by next week, that agent will be fired from the Shield!

A world of superheroes, but who controls everything is "only" a game developer.

“For those who dare call themselves gods, I, Wen Ran, will crush their legacy beneath my feet. Even dogs are more honorable than those filthy bastards!”A feared Godslayer, who, due to betrayal, perished under the might of the heavens, having his world destroyed. Saved by a mysterious system, Wen Ran was granted a second chance at life but reincarnated in the body of a lowly slave. Hunted by the gods who sought his head, Wen Ran vowed to reclaim his title by showing heaven his vengeance as a 'God Slayer.'

After being killed, Xu Turan was given a system and got pulled into a certain thriller romance novel. There, she became the crucial female supporting role who seeks death. However, on the first day of transmigrating, her system was urgently recalled for repair as it was aging.

As their farewell was imminent, the system was worried about its new host so it repeatedly reminded Xu Turan: [Your role is to be a supporting character who is always seeking death. You do know what that means, right?]

Xu Turan recalled her rich experience of doing just that in her previous life and she replied affirmatively with absolute confidence.

So the system withdrew with its mind at ease.

After a few days, the system that had been away for repair finally returned. When it looked at the situation, it almost malfunctioned: [What are you doing?!!]

Xu Turan, who was busy arguing with the Evil God, answered without thinking, “I’m doing what you asked me to do – trying to find ways to die.]

System: […?!]

“Reincarnated into the World of Magic as a demon, the last thing Davis expected was to grow up right amidst the arms of angels. Ever since the group of philanthropic angels took pity on his miserable birth and adopted him, Davis has been forced to keep his evil identity a secret while he signed in to the system.

“”Ding! The Host has signed in at Angel’s Pond, ‘The Saint’s Halo’ is rewarded!””

“”Ding! Devil’s blood activated. Sign in error. ‘The Devil’s Curse’ is additionally rewarded!””

“”Ding! The Host has signed in at God’s Throne, ‘Gold’s Holy Axe’ is rewarded!””

“”Ding! Devil’s blood activated. Sign in error. ‘The Devil’s Manifistation’ is additionally rewarded!””
