[Multiple time travelers + no female protagonist + cool story + system sacrifice]

Time Traveler No. 1: I, the third brother of Jinwu, want to build the most powerful demon court!

Time traveler number two: I am the Thirteenth Ancestor of Witches, and I want the Witch Clan to dominate the world!

Time traveler number three: I, King Dong, want to establish the most powerful immortal court!

Time traveler number four: Old thief Hongjun, give me your life!

…

Countless time travelers descended upon the prehistoric world, claiming themselves to be the protagonists of the prehistoric world. They punched the Three Pure Ones and kicked Zhunti in an attempt to overthrow Hongjun's rule.

Hongjun didn't care about this at all: "How dare a mere time traveler be so presumptuous! Come on! Release Hongtian!"

Thus, the story of Hongtian, Hongjun's biological son, and many time travelers begins!

[Original Nature-Type Popo Fruit] [Veteran of the Roger Pirates] [Gold, Silver, Bronze, and Iron] [Supreme Orange Juice] [The First User of the Face Fruit]…

As a witness and firsthand experience of both the old and new eras, Kyle’s achievements are countless, but when it comes to turning points in his life, he can’t help but recall an afternoon when he was six years old.

“A… Ace?!”

No, no!

Sorry, sir, I didn’t recognize you just now!

This is clearly Ace’s father—young Gol D. Roger!

“Little Kyle, I’ve taken a fancy to you! Are you interested in going out to sea with us? Let’s see what the ocean really looks like!”

The legendary succubus unleashed her power, and the only thing she could hold back was this↑

…

Decades later, during the Battle of Marineford, a mature, middle-aged handsome uncle descended from the sky.

“Ah, Mina-san, excuse me, it’s time for my naughty nephew to go home for dinner!”

It's a crossover anime/manga series, not featuring a single female protagonist. It's similar to Ultraman and includes content related to Your Name, Kaguya-sama: Love Is War, Lonely Rock, Oregairu, and more.

Zuo Zigong traveled through time.

Liben has traveled to a parallel universe.

He transmigrated into the body of a handsome Chinese man studying in Tokyo.

In this special parallel universe, there is Shuchiin High School, Sobu High School, Itomori Town, Shinomiya Foundation, the End Band, and many, many other things that once only appeared in anime.

This seems like a good start?

However, at the same time, Zuo Nong also received a legacy from an extremely ancient civilization.

From this legacy, Zuo Zigong learned...

The world-destroying monsters are about to arrive one by one, and he will need to transform into the final giant to fight them.

Reborn in the Dou Qi Continent, he actually became Xiao Li and even awakened the "Many Children, Many Blessings" system!

There's no way around it; as a transmigrator, I can't very well refuse the system, can I?

...

Xiao Yu: "I will only love Xiao Li in this lifetime."

Xiao Xun'er: "Brother Xiao Li, don't you want to take responsibility for me?"

Little Fairy Doctor: "He is the only light in my life."

Yun Yun: "You little rascal, you just want to bully me!"

Queen Medusa: "I have never submitted to anyone, you are the first."

...

Years later, Xiao Li stormed the Soul Clan, his spear pointed directly at the Soul Emperor.

"Is it you who spread rumors everywhere, saying that my Xiao clan has declined?"

I have obtained the legacy of a mysterious multiverse-level civilization, and can travel to countless anime worlds.

So what to do next? For passion and excitement? To meet beautiful girls? To save the world from doomsday? Or fight for all that is good? Or is it about establishing a super organization that spans countless worlds? What are you thinking? Only children make choices. As an adult, of course I want them all. Take them all!

Lin Fan traveled to the continent of Teyvat and inherited a grocery store in Liyue Harbor at the beginning, intending to just let it run wild and get by.

But one night in a warehouse, he found a blue-haired girl who was unconscious due to overtime work and had a beautiful sleeping face!

[Ding! The Human Fireworks System has been activated! Goal: Let Ganyu sleep peacefully. Reward: God-level talent!]

From then on, his shop became the strongest shelter and holy place for slacking off in Teyvat!

Guests from the Wangsheng Hall come to buy things on credit every day, and they always ask, "Put it on the Wangsheng Hall's account."

The demon-slaying sage Xiao squatted on the roof just for a bite of almond tofu.

Qixing Secretary Gan Yu stayed on his bed and begged for a refill of refreshing flower tea.

The clever Walnut always wants him to book the Wangshengtang set meal in advance!

When the vortex demon attacks, Liyue Harbor is in danger.

Lin Fan hung up a sign that read "Closed Today" and said helplessly to the "ordinary" customers in the store:

"Mr. Zhongli, stop dishing out walnuts. Your (former) subordinates are about to be drowned."

"Ying, stop playing games. It's time to unsheathe your Wuxiang sword."

"And Wendy, stop pretending to be drunk and get up and work!"

He just wanted to be a quiet shop owner, but these big-name customers were all hidden top gods?!

My name is Yotsuba Mahiro, a time traveler.

Sent to the Demonic World by an alternate-world teleportation ambassador, I became a Adjustment-Type magician of the Yotsuba clan.

Besides being born with eyes capable of replicating all forms of magic and physical techniques, perhaps my greatest supporter is my cheap mother, Yotsuba Maya.

After fifteen years in the gloomy Fourth Research Institute, my cheap mother suddenly gave him a crucial task.

"Although you're a Adjustment-Type magician of the Fourth Research Institute, you're also my child."

"So, it's also your duty to produce a worthy heir to the Yotsuba family."

It's just about carrying on the family line, a simple matter. Is the bloodline of the Ten Master Clans and the Hundred Houses enough? What if

I add your sister Miya? What if

I add the lolita from the Black Bullet world?

What if I add the assassination group from the Zelda: The Sisterhood?

What if I add a singing diva from Guilty Crown?

...

After traveling through ten worlds, he asked Maya again.

"Is that enough now? If not, I can add more!"

Volume 2: Black Bullet

Volume 3: Return to Mahouka

Teyvat suddenly descended upon the [Parallel World Exposure] system.

The world of Teyvat is sunny on the surface, but secretly it is full of regrets and sad destinies that can only be witnessed but cannot be changed.

In the parallel world of Teyvat, under the leadership of the fifth descender Su Bai, the people of Teyvat actually embarked on an expedition to another world and created a world of Teyvat where the power of gods is everywhere.

Nashida: "I was able to conquer a world? But I finally saw the living Great Mercy Tree King."

Lei Dianying: "Raiden Mei, she is indeed very powerful."

Walnut: "I am the King of Hell, controlling the reincarnation of all souls in the world?"

Ying: "Damn it, we're both Adventers, but the gap between us is so huge?"

Paimon: "Ying, you in the parallel universe have already fallen."

However, while the people of Teyvat were shocked by what Su Bai had done, they were unaware that from the moment the parallel Teyvat expedition was revealed, Su Bai had already begun his expedition to the original Teyvat world. ...

[Daily Farming + Creative Path + Invincible Boss + Beast Pet + No Female Lead]

Qin Shou, who was suffering from organ failure, closed his eyes, kicked his legs, and opened his eyes again, only to find himself in a group of refugees fleeing famine in ancient times.

Good news: Rebirth

Bad news: Your body will remain the same as your previous life, with only half a year to live.

Good news: There are warriors in this world who possess extraordinary powers.

Bad news: My weak body cannot practice martial arts

Good news: Qin Shou found that his understanding was growing every moment.

Good wind helps me soar to the sky.

With the blessing of infinite enlightenment, Qin Shou created his own way based on the Taoist canon and Buddhist scriptures of his previous life and successfully extended his life.

I lived the leisurely farming life of my dreams, picking chrysanthemums under the eastern fence and leisurely gazing at the southern mountains.

*

Since when, the small Waner Village has become a forbidden area in the eyes of martial arts masters all over the world.

Thirty years ago, the apostate Saint of the Blood Lotus Sect disappeared in Qingshui County and reappeared, slaughtering the century-old sect that had been causing trouble.

A hundred years ago, the prince of Chu fled here. Ten years later, he successfully restored his country, created a prosperous era, and became a wise ruler.

Three hundred years ago, the invincible Dugu Jiujian went into the mountains to seek his way and disappeared. But now there is an old man guarding the ordinary farmyard.

Eight hundred years ago, the Demon Lord of the cholera world entered the world to dominate the world and wipe out the hidden masters, but he disappeared in the Baiyue Mountain area. Not long after, the world's largest sect disintegrated and turned into the dust of history.

The world goes on and on, for hundreds and thousands of years, and the world changes drastically, but only one person stands outside the chess game and watches indifferently.

Someone asked, are there immortals in the world?

Countless overlords who dominated an era had a figure in green clothes in their minds, who replied decisively, "There is an immortal."
