Water, earth, fire, and wind. People who can control one of these elements are called firebenders. As a result, four nations and tribes were born in the world: Water, Earth, Fire, and Air.

Among them, only the Avatar-Avatar can master all four elements at the same time. It serves as a bridge between the four nations and maintains the balance of the world.

However, just a hundred years ago, the Avatar-Avatar suddenly disappeared. One of the four nations, the Fire Nation, launched a war of aggression against the other three nations, which lasted for nearly a hundred years.

At this time, Kahn traveled through time and became a young firebender...

[Hot-Blooded High School + God-Level Choice + Hot-Blooded District + Landlady + Gangster Daughter + Chaebol Princess +…]

In his previous life, Ryuzaki was a powerful gang leader, but he was treated like a dog by the consortium, discarded after being used, and his body was sunk in the bay.

After being reborn, he became the weakest punching bag in Suzuran High School, and the beginning was a suicide scene?

It doesn’t matter, the god-level selection system is activated!

[Option 1: Knock down the thug who came to provoke you with one punch. Completion Reward: Physical recovery, Strength +10!]

[Option 2: Endure silently and leave. Completion Reward: Earn the title "Ninja Turtle"...]

Do I even need to choose?

From dominating the lily of the valley and stepping on the hibiscus, to integrating Kabukicho and annexing the Yamaguchi-gumi...

Standing on the top of Tokyo, Ryuzaki Shin said calmly, cigarette in mouth:

"My rules are the only rules in Tokyo!!"

Zhang Hong traveled through time and thought he could awaken the golden finger like his predecessors who traveled through time.

As a result, Zhang Hong discovered that he had become a system administrator and a golden finger for others.

Fortunately, administrators also have their own benefits.

The main world is the world of Shoji.

The copy world is mainly composed of the captive world of Cooking Master and gourmet food.

In addition, this book should have multiple female protagonists as expected, which needs to be emphasized.

Tennis genius Ye Feng traveled to the world of Prince of Tennis. From then on, the world had a legend of a great devil.

He possesses an unrivaled body, strength beyond the limit, and an all-conquering spirit!

The five senses, the realm, the state of selflessness, the limit of repeated tempering, the limit of brilliant talent, the limit of perfection! Ashura Shinto!

Countless special moves will become even more powerful in his hands!

He knows what you know, and he has what you don’t have!

There is no strongest Ye Feng, only a stronger devil!

Starting from Rikkai University, Ye Feng's name will be imprinted in the Ganges of history!

When he was in Konoha, he started out as Tsunade's childhood sweetheart. This start required him to change his fate.

The tragedies of World War II and World War III, and the decline of Konoha, all disappeared.

I want to hold Tsunade's hand and walk step by step to the top of the ninja world.

Uchiha Madara, Otsutsuki Kaguya, come if you can!

Mu Yue traveled to the world of Naruto and became an ordinary chuunin teacher at Konoha Ninja School and a member of the Root Organization.

Fortunately, after awakening the teacher system, you can become stronger by teaching.

In order not to become Danzo's consumables, Mu Yue worked hard to teach and increase her strength.

"Complete the teaching rated A for the first time and receive the reward - mastery of fire attribute chakra properties change."

"Under your guidance, this disciple has worked hard to practice, and his overall strength has been greatly improved, and he has been rewarded - the Immortal Human Body!"

From then on, there was a teacher in the ninja world who only wanted to make his students strong.

Shisui was not blinded by Danzo, and he successfully prevented Uchiha from annihilation.

When Metkai met the Seven Ninja Swordsmen, he no longer watched helplessly as Metkai opened the door to death and fought hard.

Obito defeated Uchiha Madara's conspiracy and did not turn into a psychopath. He was still the enthusiastic young man who was eager to help others and wanted to become Hokage.

(ps: There is a high-quality old book on Naruto with 21.78 million words, quality guaranteed)

Originally just a regular sports anime fan on Earth, he suddenly finds himself transmigrated into an anime world. Awakening the template of Akashi Seijuro, he initially believes he has entered the world of Kuroko no Basuke.

But it isn’t until he hears the name of the man standing at the very peak of the world that he realizes—this is the realm of killer tennis!

He acquires Fudomine Middle School, establishes a brand-new tennis club, and gathers all the top-tier players from the junior high world. Using the power of the template system, he accelerates each player’s growth.

Through that, he leads them to a three-time national championship victory and onto the U-17 world stage
