MTL - Quick Transmigration: The Villain Is Delicate and Soft - Chapter 10

Tong, a sinner who was suffering endless torment in hell because of his mistake he had done in his previous life, was giving other chance to redeem himself by the devil.

Kuramoto Daisuke, a freshman in High School was suddenly exposed to someone vanishing in front of him. Turns out he was admitted to a Special Class full of Isekai Heroes that were regularly summoned to Otherworlds since the start of their Middle School. He was told that he was to become their Support to prevent each of the Heroes' fate of dying in the world they were summoned into. Though mediocre, he realized that his ability has a great potential but it needs a lot of hard work on his part.

Unconvinced of being just the Support Character, he vowed to excavate his mediocre ability, all the while supporting the Heroes using it.

And maybe more.

Before going to college, an ordinary high school student went to celebrate and got drunk. When he woke up, he found himself in a completely different world. There was a big sect, the approaching sect entrance examination, a slum where his body’s previous owner lived, and a shared memory about a missing young girl.

When he got tangled in a fight with a few punks in this different world, he fell off a cliff and miraculously found himself still alive, with two more voices ringing inside his head. They were Sword Master and Saber Master. In the company of them, he continued to find out more about this whole new world. He took the sect entrance examination, entered the sect, met a strange man in black, and even participated in a major competition of the sect to have a chance to win over his peers!
In this whole new world, he was born again and got to explore the fantastic martial world!

It was well known that in every novel, there would always be a supporting male character like this:

They were either crazy about the female lead or willing to work.

Even if they gave themselves a green hat, they were ready to.

The female lead was misunderstood by the male lead, so he came to explain.

The female lead had career problems, so he came to help.

In the end, he only got a sentence from the female lead: “I just think of you as a brother.”

He could be used against the male lead. In the end, the male and female leads ruined him as the strong prevailed over the weak.

After Gu Jingyu became one of those miserable supporting male characters in the novel…

The heroine of the domineering novel said: “I just think of you as a brother.”

Gu Jingyu: “Thank you. My mom only gave birth to me.”

The heroine from the modern-day time-travel novel: “This is a vegetarian snack that I have carefully developed for you. I think you’ll like it.”

Looking at the spicy veggie meat stick in the heroine’s hand, Gu Jingyu fell into silence. Did he look like a fool?

The useless protagonist in the immortal cultivation novel said: “For thirty years, people east of the river prosper, then for another thirty years those on the west prosper: life is full of ups and downs. Don’t bully the poor youth! You wait, I will definitely come back to take revenge.”

Gu Jingyu directly imprisoned the protagonist until he ascended.
