MTL - Shoujo Grand Summoning - ~ 1898 Interference! Speed ​​up the pace of change! ...

Earth has once again descended into chaos with the rise of the Exiles—mysterious and powerful monsters intent on dominating humanity. In response, the defenders—the army—deploy modern weapons and the dwindling resources at their disposal, but soon find these measures ineffective as the Exiles begin to evolve.In this desperate situation, a group of innovative scientists develops a groundbreaking serum that grants extraordinary abilities to those who take it, resulting in the emergence of Beholders—meta-humans, ability bearers, and superhumans. It is about time for humanity to evolve alongside its adversaries.Sky, like his colleagues, receives the serum. However, instead of the expected powers, he acquires something far more stronger —a trait linked to disaster. Additionally, he must deal with its numerous side effects, which are rather extraordinary.

Vainqueur Knightsbane is your average dragon: a giant, fire-breathing lizard who loves to take naps on his golden hoard, kidnap princesses for fun, and make the life of adventurers miserable. Vainqueur's only pleasure in life is to watch his treasure get bigger, one coin at a time.

So when a would-be thief turned unwilling minion tells him about "classes," "levels," and "quests," Vainqueur wonders if maybe, just maybe, he should consider a career change.

After all, why bother hunting monsters for free when you can get paid for it?

When I became a rich young master, I had to enjoy it.
Training? No!
That is so boring.
I have a system, no need for training.

Are you hungry? Come, I will treat you with some food at a luxurious restaurant.
What a poor homeless. Come, I will give you a house.

I, Lin Fan is a good person.
