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!"

Lu Sheng transmigrated to ancient times. On the day she arrived, the original owner of this body was selling her daughter and was caught red-handed by her wife. Her wife's eyes were like a biting winter storm, chilling Lu Sheng to the bone. Lu Sheng took the blame and apologized: "I promise I'll change my ways and live a good life with you." Qi Zhenshu: "Let's get a divorce." Having come from the apocalypse, Lu Sheng loved this world with its clear blue skies and sparkling waters.

System + slow start + low opening and high closing

You can enter with confidence!

Zhou Yu, who is about to graduate from university, comes to a high school in a rural town for an internship.

At an internal meeting of school leaders.

Principal: Last year, our school didn't have a single undergraduate student. This year, if we don't achieve good results, our high school will be closed. We have to think of a solution!

Vice Principal: What can we do? Our teaching staff isn't as good as other schools, and the students we're recruiting are getting worse every year. How can we teach them? The students don't have good foundations to begin with!

Principal: That's not the way to say it! So, let's gather all the elite teachers in the school together! Create a key class! One for arts and one for science! Then, use the remaining resources to create a pilot class! And finally, for those students who aren't wanted, we can create parallel classes!

Vice Principal: Who will lead the parallel classes?

Principal: Aren’t there a few intern teachers assigned here? Let them take it!

Zhou Yu, a trainee teacher: Ah? Me?

But, it doesn't matter. Zhou Yu, who hasn't graduated yet, is not afraid at all, because he has awakened the 'Super Class Teacher System', which can comprehensively improve the level of students!

After the college entrance examination.

Principal: Holy crap! The key classes and the advanced classes were completely wiped out! How come half the students in that intern teacher's poor class got into college?! No way! This talent must be kept in our school!

Other principals who got the news said: "Teacher Zhou! Come to our school! We'll get you a job!"

Private school principal: Teacher Zhou, come to our school! We'll give you shares! 100,000 yuan a month!

Student’s parent: Teacher, please let my child enter your class!

Faced with the crowd's scrambling, Zhou Yu smiled slightly.

Shako, a seasoned office worker, accidentally died from electrocution while slacking off at work and watching One Piece. His soul was transported to the One Piece world and he was rescued by Whitebeard. He eventually recognized the pirate as his father, changed his name to Shako, and became Edward Newgate's eldest son and the vice-captain of the Whitebeard Pirates.

Shaq: "Hahaha, that old devil Im's era was called Whitebeard!"

Whitebeard: "Gurarararararar, what do I, an old man in my seventies or eighties, know? If you have something to say, go talk to my good-for-nothing son."

Decades after Whitebeard reigned supreme over the seas, people were astonished to discover that this old man showed no signs of aging. Even more terrifying was that if anyone coveted his throne, they would be met with devastating attacks and the whispers of a demon.

"Hahaha, what kind of Tom, Dick, or Harry dares to disrespect my old man?!" (The synopsis is insufficient; please proceed to the main text.)
