He traveled through time and became the cousin of Nara Shikamaru of the Nara clan in Naruto. Nara Shikahaku has a deductive transformation system. He said that although his chakra attributes are not enough and he does not have a special bloodline limit, he has a family secret technique.

What? You're saying the shadow isn't that long? The blood vessels in the human body are about 100,000 kilometers long. So, it's scientific that my shadow would become thinner and longer from the Fire Nation to the Water Nation, right?

Killing from a distance? Doesn't Shadow Seam allow you to concentrate chakra and thrust to kill? What? How do you break through the Lightning Release Chakra Coat? Doesn't Shadow Slap Technique increase strength?

How do you control the tailed beasts? Isn't the most basic shadow imitation technique enough? It's common sense that shadow imitation can freeze the body, right?

How can I defend against the Tailed Beast Balls alone? Gaara can use sand to defend himself, and the Raikage can also use chakra cloaks. Isn't it reasonable that my shadow can transform into a barrier?

Don’t disbelieve me, this is really a secret technique passed down from my family.

The Gate of the Heavens has descended, and everyone can resonate with the copy of the Heavens!

The time traveler Ye Yang resonated with "Devouring the Starry Sky", but it was the Earth in the early stage of the Great Nirvana!

The RR virus was rampant, but the examiner mistakenly judged it to be a low-level copy of the outbreak of a biochemical crisis and had no potential.

But only Ye Yang knows how powerful this copy is.

"A resonance copy is influenced by one's inner thoughts. Even the lowest-level copy... How unambitious is he?"

"Shame on him!"

Amidst the contempt of his fellow townspeople, Ye Yang was admitted to university in the most humiliating way.

Just so that one day, I can stand on the highest ground and justify my former self:

"This is Devouring the Stars, not Resident Evil!"

Jiang Chen traveled through time accidentally and began his journey in anime.

The world is tentatively determined to be: Naruto - Attack on Titan - Demon Slayer - Sword Art Online - Detective Conan, etc.

In the Naruto world, Jiang Chen obtained a system that gives him a 10,000-fold return on his disciples. As long as he teaches his disciples, he can get corresponding high-fold return rewards.

As a reward, Jiang Chen taught Hinata the black coffin of the ghost way that he brought from the world of death.

During the Chunin Exam,

Neji: "Give up, Hinata, you are not fit to be a ninja."

Hinata: "I don't want to run away anymore, Neji-nii, let's have a showdown! A faintly turbid emblem reveals an unruly and arrogant talent...Hadō no 90: Black Coffin!!!"

Everyone: "She calls me brother, but she kills me. This girl is so scary!"

The story of a struggling cosplayer who was suddenly thrust into the world of Naruto. Xio: How can I survive without a system? Chrollo: Since you're cosplaying me, I'll teach you a few things. This is the story of ordinary people, filled with selfishness, philanthropy, cold-bloodedness, and tenderness. Human nature is not static, and good and evil are divided into camps and positions.

Yang Yu traveled to a parallel world where everyone could awaken their profession at the age of 18.

S-class geniuses can destroy the world, A-class elites have a bright future, but he has only awakened an ordinary D-class professional warrior.

Just when he thought he could only be a low-level soldier in this life, he awakened his hidden talent and worked two hundred times harder.

Release all skills once and gain 200 times the proficiency!

While others who practiced for a month without making any progress could reach level 10 in one day, he could do so.

Wanjian Guizong, while others’ proficiency levels are reduced through practice, he can directly max it out.

While the whole school was still marveling at the school belle's career, Yang Yu had already cleared the dungeon and broken the record.

The school beauty was defeated by this.

When the demonic tide of the abyss hit and the strong men from various countries were in despair, Yang Yu came from the air.

"Actually..." Yang Yu smiled shyly, "Actually, I've already become a god!"
