I Sacrifice Myself?

"With a cheat this massive, can I really handle it?" The youth named Li Yu, possessing delicate features and dressed in casual attire, stared at the room before him, his face etched with panic.

Half an hour ago, he had been transported here from his home and learned exactly what kind of hellhole this place was.

To put it in a single sentence: this world is a giant cesspit containing every nightmare imaginable, all of which supposedly emerged within the last decade.

With the resurgence of spiritual energy, demons run rampant, and there are even creatures from other dimensions and extraterrestrials—goblins, slimes, and the like—constantly pouring out of spatial rifts.

It is fair to say that the entire world has been thrown into chaos by the arrival of these entities.

However, it is not without its benefits; following the appearance of these beings, humanity has gained access to significant technology and special powers.

Originally, this was just an ordinary technological world, but with the emergence of these spatial rifts, the entire globe began to veer down a different path.

The world began to head down a new path; beyond just technology, humanity started to master powers that were previously confined to the realm of fantasy.

According to the information Li Yu possesses, there are several ways for humans to acquire power, though the mainstream approach remains systematic training provided by the state.

Those with natural talent awaken certain aptitudes or superpowers from birth, while those who cannot awaken must rely on personal study to grow stronger.

Another method is to obtain power from interdimensional rifts, as these forces are gifts from other worlds.

Li Yu organized the information in his mind; if nothing went wrong, the power he had just acquired must have come from another world.

"Eye of Keigeko, the ultimate eye capable of seeing through all phenomena; learn it at a glance, master it at a second look." Li Yu couldn't help but mutter to himself.

Recalling the other version of himself he saw when he first transmigrated to this world, Li Yu fell into deep thought once more.

When he first appeared in this world, a guy who looked exactly like him summoned him out, and before he could even be surprised, the man merged directly with him.

Then, he merged with him, bestowing all his memories and identity upon him.

It was as if he had finally found release... After sorting through the memories left behind, Li Yu roughly understood why the other had thought that way.

Because this world is truly wretched, and the power he awakened was a one-time-use ability: summoning a version of himself from a parallel world to take his place.

"What a sin! What is this? Dragging someone else here to suffer?" Li Yu grumbled as he pulled out an ID card.

This was his identity information in this world: a high school student facing the upcoming class placement, eighteen years old this year!

According to the memories, the parallel version of himself suffered from severe depression and had long since lost the will to live, which, combined with his awakened talent...

"You might be fine now, but I'm the one who's screwed. It's a good thing you were a loner with no friends, or this would be a real headache." Li Yu couldn't help but complain while looking at the ID.

It's just as well; he had transmigrated in his own body, so he wouldn't end up as a mech pilot or a person without legal status.

With the memories of the other him, living in this world shouldn't be a problem; after all, the original owner was an orphan with no friends and almost no social life.

So, Li Yu only needed to follow the established routine and slowly make changes to fully take over the original owner's identity.

After tidying up the original owner's ID and wallet, Li Yu began to examine his surroundings.

According to his memories, he was currently in the apartment the original owner rented—a small studio of only a few dozen square meters, filled with simple daily necessities.

Li Yu frowned as he looked at the household items; even though they were used by the other him, Li Yu didn't like them and had to replace them all!

Glancing at the sky outside, he saw it was already dawn, so Li Yu decided to head downstairs to do some shopping before considering anything else.

Taking his wallet and keys, Li Yu left the house and went downstairs, then followed the memories to find the convenience store he needed.

Aside from the monsters, many things in this world were quite similar to Li Yu's previous world.

From a small, ordinary shop, Li Yu managed to pick up quite a bit of information.

After purchasing what he needed, Li Yu returned home to wash up, then grabbed the original owner's school bag and headed back downstairs.

The other guy was still a high school student, and one who had to undergo class placement this year.

According to the memories provided, today was the day to report his awakened talent.

The school would then assign him to a class based on that talent, and it was precisely because the original owner had awakened such a strange ability that he had chosen to give up.

Honestly, the original owner's talent of sacrificing himself to summon a parallel version of himself was truly bizarre.

After all, who would be willing to let another version of themselves replace everything they were?

It was as if he were nothing more than a sacrifice; the appearance of such a talent completely negated his entire existence.

Coupled with his existing depression, he had simply lost hope, and the moment he learned of his talent, he had used it without hesitation.

A talent that could only be used once in a lifetime, a talent for release, had been activated.

Then, he pulled the Li Yu from a parallel world into this one, and... Li Yu had also successfully awakened his own talent.

"The other me really had it rough!" Li Yu sighed, not dwelling on the issue any further.

Since things had come to this, the only real path was for Li Yu to live well in this world in his place.

Grabbing breakfast on the side of the road, Li Yu walked toward the school according to his memories.

Just like in his previous life, many elderly people liked to come out for morning exercise, but the martial arts these seniors were practicing were no mere flashy displays.

They were genuine, lethal techniques. Li Yu took a glance, and the patterns of the martial art one of the seniors was practicing instantly surfaced in his mind.

This caused Li Yu to stop and watch for a few more moments, and at that instant, his talent began to take effect.

With just a single look, Li Yu mastered it; then, after watching a few more times, he felt changes occurring within his own body.

His physique was strengthening, and the martial art was forming muscle memory in his mind. In just a few seconds, it was as if Li Yu had been practicing for decades.

Glancing at the old gentleman who was swinging his weapon with such vigorous flair, Li Yu wore a strange expression; this cheat of his was truly terrifying!

After sensing his current strength for a moment, Li Yu felt that with a single slap, he could have killed the version of himself from just a few seconds ago.

In high spirits, Li Yu continued to observe the other people exercising in the park, naturally wanting to learn as much as he could while he had the chance.

In the park during the morning, there were quite a few elderly men and women brandishing blades and spears, and these people were likely retired from various backgrounds.

The techniques they had mastered were all practical, combat-oriented styles, making them incredibly useful for Li Yu.

In just a few short minutes, Li Yu had mastered multiple martial arts through his talent, and his physical fitness had improved by several tiers!
