Worse yet, Axel’s powers comes with a weakness—one he doesn't know exists… but the villain does.[A/N: This novel includes intense battles, strategic fights, and moments of gore(not extreme or too detailed), which is why I’ve used the R18 tag. Axel will be powerful as a superhero, but not overpowered—every victory will be earned. Expect detailed fight scenes and epic showdowns that will keep you on the edge of your seat or the road (considering what you're doing at the time of reading ^⁠_⁠^)The first villain Axel faces in Chapter 3? Let’s just say I have big plans for him. He’s not just an obstacle—he’s a key piece of the story.I’ll be releasing three chapters daily, and I promise, I won’t drop.]No Harem!

When Shen Yu woke up, he had accidentally gone into a ridiculous dog blood novel.

In the novel, he is a poor cannon fodder character, dead father and mother, fiancée runs away, drags a pair of legs and lives lonely in a 20,000-square foot mansion.

Later, in order to compete for the female lead, he died under the opposition.

In order to save his life, Shen Yu had to stay as far away as possible from the leading and supporting roles and concentrate on enjoying the luxury life.

As a result, one day, the servant brought a 10-year-old villain with bruised eyes: “Sir, this is the orphan of Tang’s family.”

Shen Yu: “…”

Shen Yu decided to adopt the small villains and change his fate.

Ten Years Later.

The villain pushed Shen Yu to the corner: “Who is that woman?”

Shen Yu: “… Who do you say?”

The villain: “The woman who seduced you at last night’s banquet! “

Shen Yu: “…”

The villain: “Hehe, I’m going to kill her.”

Shen Yu: “My son… That’s the female lead you forgot by the Lake…”

They come, the security;

Became Don Quixote Rossindi?

Forget it, it can’t be reopened;

But after realizing that he had eaten the fruit of silence, the little boy became restless.

Fruit of Silence, this is one of the devil fruits that can compete for the title of “the most useless” in the world of One Piece; it is only a little better than Chopper’s “Everyone’s Fruit · Common People’s Form”!

“Dover, you said you are a devil fruit wholesaler, why do your family eat all kinds of weird ones?”

Facing the bewildered little Dover, Rossindi patted his forehead.

“Forget it, let’s practice domineering hard.”
