Heroic spirits, celebrated for their achievements, become heroes. Accidentally traveling through time and space, they gain access to the Heroic Spirit Achievement System, where their deeds are solidified into attributes, abilities, and skills...

Even if you haven't read the original work, you can still read it as original...

The protagonist, Lin Yan, is a modern-day engineering PhD proficient in mechanical engineering, materials science, and social management, as well as a survivalist. He transmigrates into the body of a useless, exiled noble young master in another world. His cheat ability isn't combat magic, but rather near-absolute "logical modeling" and "material analysis" abilities, allowing him to quickly understand and optimize the technology of this world.

This is an alternate world where magic (elemental power) and martial arts coexist, but the social structure, production technology, and ideology are relatively backward. Magic and martial arts are toys for the privileged class, while the common people live in poverty.

The protagonist does not pursue the ultimate in personal martial arts prowess, but instead uses modern knowledge to launch a sweeping "industrial revolution" and "social transformation" from scratch. He uses the power of technology, systems, and ideas to fight against the corrupt aristocracy, the mysterious magician class, and the powerful martial arts sects, ultimately reshaping the entire world order.

In the era of big data, Yang Lin awakens a hidden profession—Domain Demon Slayer.

However, before he could even get excited, the harsh reality quickly plunged him into despair.

Fixed damage is only 1!

Professional skills: None!

No occupational terms listed!

Entering a dungeon in this state is practically suicide.

Just as Yang Lin was being advised by the principal and his homeroom teacher to give up his career and pursue a humanities degree, he discovered a hidden clue about this hidden career...

He cheated his way into obtaining the Tathagata Palm in "Kung Fu"! He plundered the Iron Man manufacturing technology in "The Avengers"! ...In this world where everyone is reincarnated, Xu Long, who knows all the plots, is the biggest winner!

[Incredibly satisfying][Naruto][Multiple female leads] "My name is Yang Jian. When you see this sentence, it means you've already seen this sentence." Yang Jian transmigrated to the world of Full-Time Magister and became a summoning mage. When Yang Jian first performed a dimensional summoning, he summoned Kurama. That was already outrageous enough. Even more outrageous was that after recovering from his eye ailment, Yang Jian stared blankly at his own eyes in the mirror. They were a pair of blood-red eyes with tomoe...

Absolutely impossible!

How can you avoid the master's secret inheritance!

Bolan: I admit that your talent is indeed strong, but I will not admit defeat!

Original Ancestor: This kid is interesting.

He can perform these messy things independently of the original universe system.

Although it is a bit weak at present, it is also a direction to try.

The moment Ji Shu transmigrated to Blue Star World, he found that he was carrying a Talent Tower. Every time a level of the Talent Tower was lit, he would automatically have more than one talent.

[Slow-paced training + no female protagonist + Hunter x Hunter world adventure]

Zhao Tianming transmigrates into the world of Hunter x Hunter for the second time. Having already transmigrated into the world of One Piece, he awakens his Haki once again. In order to learn Nen, he takes the Hunter Exam, but unexpectedly gets entangled with Hisoka.

That said, Hisoka is actually a pretty good guy, except for his habit of being naked in front of me all the time...

P.S.: I really like Hunter x Hunter, so I got carried away and started writing this. But I only realized how troublesome Hunter x Hunter fanfiction is when I was halfway through. All the messy Nen abilities and world-building made my head spin.

My new book, "Oh my god, how did my electronic girlfriend become Si Ming?", has been released.

[Apocalyptic, game data stream, no female lead, no saintly characters, completely self-serving, ruthless and decisive, a thrilling read]

The apocalypse has arrived, order has collapsed, and countless terrifying monsters and natural disasters have been unleashed.

Humans become players; by defeating monsters, they can level up, become stronger, and stand at the top of the world!

In his previous life, Shen Jin devoted himself to rebuilding human order, but he touched the interests of the powerful and wealthy, and was killed by them and turned into a puppet slave.

Having been reborn, Shen Jin brought back the mysterious rune sequence number 001, Primordial Beginning! It possesses the ability to fuse!

[Dagger] + [Deadly Ghostly Aura], obtain the weapon [Ghost Blade]

[Slash] + [Flame Heart] grants the skill [Flame Blade Heart-Slicing].

This time he realized that those powerful and wealthy people only treated ordinary people as slaves, and as long as they were around, ordinary people had no chance to rise up.

This time, Shen Jin chose to travel alone!

No longer contributing to anything.

In his eyes, the powerful and wealthy were nothing more than mutts.
