God's Left Hand - Book 1 — Chapter 19

A girl who calls herself a demon appeared before a timid student named Fumio Kijima. The girl claims to be a campaign girl from the demon world and she gives him the ability to “summon a room” from nothing but thin air.

At first he doesn’t abuse his power and uses it as a convenient ability in his every day life. But one day he is bullied by his classmates under a false pretext and is made to suffer. In the past he would have wallowed in misery and cried himself to sleep, but now he had a power to call upon.

“I will make them regret it!”

Using his powers to summon his “room”, he begins his era of confinement and brainwashing to achieve his goals.

The gold mine silver mine diamond mine is almost weak, and the mysterious miners system is in hand.

Although there is no manual and no elf, every day I am trying to find out, but my brother can dig it out.

From the practice of meditation, alchemy materials, spaceships, and mechs, life is different.

There is no level that can’t be upgraded, there is no task that can’t get rid of it, but what is the system doing? Come ~ come! Still don’t say it, give me the first girl! Brother will plan again.

Ji Han, who was worried about his sister’s medical expenses, accidentally bound a money-making game.

The monsters in the other world, the puzzles in the film and television world, and the forbidden tombs in the legendary world.

Your game is too scary (love)!

What? 50,000 for completing the task? Kill a monster and give 30,000?

As an ordinary person, Ji Han shivered in the game, doing his best to complete the task to grab the head and get the much-needed monetary reward.

But in the eyes of others, he is the strongest alien warrior.

“Captain, the 10th team is really empty, they actually found a cowardly ordinary person.”

“Fart! All the monsters in the other world were killed by him alone. You fucking call this a cowardly ordinary person?”
