I traveled back to the day Konoha was founded and awakened a fancy sign-in system.

He signed in to Konoha Village as an ordinary person for fifty years.

It has everything: martial arts techniques, ninjutsu, bloodline limits, Demon Slayer breathing techniques, One Piece Haki, and more.

Due to his cultivation techniques, Thousand Hands Immortal has a long lifespan and grows younger with age, earning him the title of "Immortal Master" among the villagers.

The villagers didn't know until the night the Nine-Tailed Fox attacked the village and Thousand-Handed Immortal descended from the sky.

There is still an immortal god in Konoha!

At the same time, a cold, mechanical voice echoed in Thousand Hands Long Life's mind.

"Ding! Triggered the event check-in. Successfully checked in on the night of the Nine-Tailed Fox's attack on the village. Congratulations on obtaining: Multiverse Chat Group!"

Tony Stark joins the chat!

Portgas D. Ace has joined the chat!

Lin Feng transmigrated to the Douluo Continent, only to find himself transformed into a soul beast with no strength whatsoever, except for his cuteness. Fortunately, during a foraging trip, his cuteness earned him a Saintess, Bibi Dong, as his human servant. Having died from overwork in his previous life, and finding the outside world far too dangerous, Lin Feng, after awakening the "Idle Fish Sign-in System," became increasingly lazy and irresponsible each day! Who would have thought that Bibi Dong could hear Lin Feng's thoughts? "Little Fengfeng, give me a hug!" [A little tighter, hug me tighter!] "Little Fengfeng, a maid brought over a bowl of soup. Do you want to drink it together? After we finish, we'll go see our teacher!" [Shapi, what are you drinking? That's a sleeping potion! If you drink it, you'll be waiting to be... you know... done to you by your beastly teacher!]... Bibi Dong: "Little Fengfeng, you're truly a lucky star for our Spirit Hall!"

After traveling to Douluo Continent, I didn't expect to awaken the diary system. As long as I write a diary every day, I can get various rewards. But how can Wu Xing, who has read many novels, not know the system routines?

Wu Xing: Hey, don't think I don't know, you must be peeking at my diary!

Douluo women: ...

Zongman women: Unexpected, we are also reading it.

In the ancient times, the Emperor was buried on the star, and the Divine Dynasty was transformed...

Is this the era of the rise of the ruthless emperor?

The Empress and I got married?

Li Hanyi: Sir, I will repay you for saving my life with my own body.

Ying Zheng: Thank you, sir, for helping me live forever. My Great Qin will last forever.

Tang Zichen: Can Chinese martial arts also sanctify the body? Thank you, sir, hehe.

Ma Xiaoling: Sir, everyone here wants to destroy the world, please protect me.

Medusa: Sir, when will you come to my snake tribe to propose marriage?

Tang San: Look at my Blue Silver Grass...ah...

Morgana: I am the greatest evil in the universe, want to play?

Willow God: Sir, when will you come to see me again?

Ye Tiandi: Aren’t we brothers? Let’s have a fight with you, my dear demon.

[Immortal Body] + [Daily Login System] + [Rinnegan] + [Naruto Across Worlds] + [Invincible from the Start]

At this moment, Lingyunyun was sitting on the supreme throne of creation in the Douluo God Realm, and a hearty laugh reached his ears. "Hahaha, not bad. In just a few decades, you have become a powerful Golden Immortal Realm expert. You have lived up to my expectations."

Ling Yun didn't panic when he heard the voice. He already had some guesses about the origin of the system. So he asked, "Who is this senior?"

"I am the Shangqing Tongtian Sage, one of the Six Sages of Heaven in the Primordial World, and I am also your system..."

Luo Feng came to the world of pirates and gained unparalleled enlightenment due to an accident in time travel.

Monsters are everywhere, are the four emperors worse than dogs?

Chu Jue traveled through time and space and became a fool in the world of Zongwu.

He was raised by the head of the Tomb for eighteen years and became the senior apprentice of Li Mochou and Xiaolongnu.

At the age of eighteen, he had a conflict with the Quanzhen people. By coincidence, he realized his innate wisdom and awakened his extraordinary enlightenment.

From then on, it soared to the sky!

Since then.

Chu Jue, relying on his extraordinary comprehension, embarked on an unprecedented path of cultivating immortals!

Understand the immortal method, pass it on to all living beings, lead the world to upgrade, I am the ancestor of immortals!

When all the immortals in the world come down to earth, they must bow their heads when they see me!

That day, Chu Jue became an immortal.

Xiaolongnu was shocked: Brother, how did you become an immortal?

[Let loose! Take them all! Leave none behind! Hahahaha!] Xiao Yin transmigrated to the Douluo Continent and became the most humiliating "soulless trash" of the Seven Treasure Glazed Tile School. His childhood sweetheart, Ning Rongrong, kicked him out of the sect with a single "Miss Ning." In despair, he activated the [All Beings' Wish System], and his newbie quest was to slap the "theoretical master" Yu Xiaogang? "Slap—!" A resounding slap stunned Yu Xiaogang and awakened his dormant martial soul! When the phantom of a primordial beast with a dragon's head and a sheep's body appeared behind him—the world realized that he possessed a gluttonous beast capable of devouring all heavens! From then on: Tang San's immortal herbs? Swallowed! Opportunities? Stolen! Yu Xiaogang's dignity? Crushed! The Seven Treasure Glazed Tile School's...
