Demon Progenitor Development Project

Yi Yuyi was born in a fishing village by the sea.

Everyone in the fishing village makes a living by fishing, and Yi Yuyi has been dealing with fish in the sea since he was a child.

The children in the fishing village mostly dream of catching lots of fish, marrying a beautiful wife, and having several children—that's all they want.

The Yiyu device is completely different.

He has a natural talent for being an artist; he likes to sew fish caught from the sea together in various ways to create a strange and bizarre aesthetic.

But in this ignorant fishing village, Yi Yuyi was quickly regarded as a freak and ostracized.

If Yi Yu-yi had been born into an artistic family, this talent might have been able to flourish.

However, in the fishing village, Yi Yu Yi was a strange child, and even his parents and family kept their distance from his peculiar behavior.

However, since they were still their own child, Yi Yuyi's parents eventually acquiesced to his strange behavior after repeated attempts to reason with him and even resort to physical punishment.

After all, they had so many things to do and didn't have time to explore their son's inner thoughts, especially since they had more than one son.

Unexpected events in life always come unexpectedly.

To make a living on the high seas, one must also be prepared to be swallowed by the waves; a fisherman either dies at sea or dies on land.

Unsurprisingly, Yi Yu-yi, with her gloomy and unlikable personality, was excluded from the distribution of her father's inheritance and could only make a living by occasionally relying on her mother's help.

Even so, Yi Yuyi did not give up his artistic creations, and often went to the beach to catch fish and collect seashells as art materials.

A strange fish was crushed by a boy from a fishing village.

"What an ugly thing!"

The boy looked with disgust at the dead fish carcass that had been stitched together with various fish scales.

"You little freak!"

"They keep doing this disgusting stuff!"

"Your dad must have been eaten by the big fish because of the things you did!"

Several boys in a group mocked a ragged boy who was squatting down.

Yi Yu Yi's eyes were red. Don't misunderstand, it wasn't because of her parents, but because her work had been defiled!

To better create artwork, Yi Yu Yi has a fairly sharp knife in his hand.

Yi Yuyi stared intently at the group of teenagers, a thought suddenly forming in his mind: if dead fish can be made into art, why can't dead people?

Those dark eyes lit up, and he rushed forward, straddling the leading boy. He slit his throat with a knife, blood spurting out, shocking the group of boys around him.

These people were nothing but bad influences, and they scattered and fled in an instant.

Yi Yuyi took the body away and hid in his usual secret spot where he made his artwork, where he began to create with great passion.

But death does not mean the end.

Upon hearing the whole story, the boy's parents were furious and led the entire village to search almost the entire surrounding area, eventually finding the Yiyu instrument.

Yi Yuyi's fate was predictable; he was nearly beaten to death!

"Just leave him here!"

"Pah!" A mouthful of saliva was spat directly onto Yi Yuyi, and the crowd left angrily.

Left behind, Yi Yuyi, covered in cuts and unable to move, stared at the dark sky, fearfully awaiting his impending death.

Damn it! My work isn't finished yet!

This is the first time I've ever used dead people to create a piece of art!!

It wasn't even completely done!

Yi Yuyi was filled with regret. She should have killed all those people instead.

This idea is actually unrealistic; Yi Yuyi is far too thin and weak compared to her peers who are supported by their parents.

"Ok?"

Yi Yuyi, who had lost too much blood, seemed to hear human voices.

Having just crawled out of the sea, the demon-like Muzan Kibutsuji saw the dying Masugi, scanned his surroundings, and lingered for a moment, especially on the mangled corpse.

As for why Muzan was at the beach, that's all Shugo's fault!

After his sparring sessions, Shugo faced a new form of torment—scratch that, training method—namely, using the pressure of deep-sea water for oppressive training.

This really took a toll on Muzan, but it did have an effect; at least Muzan's physical strength increased again.

This also led to Muzan retrieving the original Upper Moon Five, Gyokko.

Shugo, who originally didn't plan to collect the jewel pot: ?
