He was transported to the Naruto world by accident and discovered that he had gained the ability to absorb energy. So he went further and further down the path of searching for and absorbing others.

He absorbed Uchiha Shisui's corpse, gaining some chakra and some ocular power, and acquired the Mangekyou Sharingan, Kotoamatsukami!

Absorb Hashirama's cells to gain a large amount of chakra, and unlock the Wood Release bloodline limit!

He absorbed Naruto's blood and gained the Uzumaki physique and Ashura Chakra!

When he absorbed everything and achieved the title of strongest, the ninja world finally ushered in true peace.

Slow pace + research-oriented protagonist + martial arts + demons + auto-play system

The path of martial arts is like climbing a ladder to heaven, requiring a clear understanding of realms, physical training, spiritual enlightenment, and the breaking of shackles. Each step is thorny, woven with blood and tears. It's a well-known fact that cultivation requires endurance beyond human capabilities—standing still in a pine-like posture under scorching sun, breathing in and out without ceasing in the bitter cold of night, reshaping meridians with gritted teeth, and defending one's true heart against the demons that devour one's soul. But how can a mortal body endure this endless arduous training? Even the slightest instability in one's foundation can lead to eternal damnation.

But I can "hang up"

【Be prudent, be decisive】

Zhou Yi traveled through another world, became immortal, and could absorb the memories of the dead.

When others were worried about money, Zhou Yi had already accumulated a mountain of gold.

When others were worried about the skills, Zhou Yi had already gathered all the martial arts skills.

…

Life and death duels in the court, bloody storms in the rivers and lakes.

Zhou Yi hid in the prison, letting the dynasties change and the world change.

The boy he once saved became a generation of sword god.

The chicken he raised casually became a peerless demon king.

The persimmon tree that he took a cool breeze turned into a great demon.

The genius he taught became famous all over the world.

After countless eras, looking back at the long river of history, there is his shadow everywhere.

Xiao Chong traveled through the Doupo world and became Xiao Yan's half-brother, awakening his incredible ability.

Thus, the Xiao family gained a young genius, and the Douqi Continent gained a Dou Emperor who suddenly appeared.

[You comprehended the operation of Dou Qi in your womb and understood the Inner Breath Heavenly Emperor Sutra!]

[You observe the stars at night and comprehend the art of falling stars! ]

[Watch Yao Lao make the elixir and comprehend the great Dao of the alchemy furnace! ]

【you……】

…

Xun'er: Xiao Yan, let's not contact each other anymore. I'm afraid Brother Xiao Chong will misunderstand.

Xiao Yan: We both traveled through time, so how come you were able to start practicing in the womb, and why do all the girls still revolve around you?

Gu Yuan: The eighteen-year-old Dou Di is so terrifying. I wish he was not a member of my ancient clan!

Emperor Hun Tian: Who on earth is Xiao Chong? He is such a monster that he became an emperor earlier than Emperor Yan and me!

Defeating a Hydra agent only adds 0.2 contribution points? Looking at the 10 million contribution points required to unlock the Sun Disk, Lin Yuan fell silent. Rebuilding Shurima's glory, Hydra shedding a little blood—isn't that a bit much? When Thanos descended, he encountered the newly unlocked Mordekaiser; when the Time Bureau wanted to annihilate the timeline, they met the time assassin Ekko; when the Celestials descended, they encountered Aurelion Sol, the Star Forger; Lin Yuan thought: It's normal for a legitimate Shurima Empire to be full of talent, right? Those who offend Shurima, no matter how far away, will be punished! [PS: Those who haven't seen Marvel or played LOL can still read this without worry; I've already mentioned every character in the story...]
