He traveled to the ancient world and became Emperor Jun.

At first, he didn't want to be the Demon King, he just wanted to be a free and easy innate divine being. However, since Hongjun Daozu had appointed him, he couldn't refuse and had to take on this important task.

As for the war between wizards and liches, Di Jun had no interest at all. He just wanted to lead the demon clan to build the prehistoric world and gain the favor of the prehistoric world and merit and fortune.

There is also the Zhoutian Star Array. Was it created for fighting?

Dividing day and night, defining the four seasons, transforming chaotic energy into innate spiritual energy, and benefiting the world, this is the true purpose of the Zhoutian Star Array.

With good fortune and merit, who would dare to provoke the demon clan?

Under the leadership of Emperor Jun, the entire demon race is contributing their own strength to the construction of the prehistoric world.

Travel to the world of Naruto and become Uzumaki Naruto. You can get rewards by writing a diary. Perfect Sage Body, Flying Thunder God Technique, Eight Gates Ninjutsu, Wood Style Bloodline Limit... Naruto plans to keep a low profile before gaining absolute power. However, Naruto discovered that the female characters in the ninja world seemed a little different from the original. Sakura didn't become Sasuke's licker, but came to lick him every day. Hinata is so shy, but she hangs around in front of him every day. As the Anbu who monitors him, Uzuki Yugao has no intention of hiding herself at all. Tsunade suddenly returned to the village, punched Jiraiya away, and shouted that she wanted to take him as her disciple! Yamanaka Ino, Yuhi Kurenai, Tenten, Konan... Looking at the women clamoring to be his wife, Naruto sighed helplessly. This is really different from what he thought!

[Invincible, Daily, Simulator, chat groups will appear in the early and middle stages. 】

As a result, every simulation of Bai Ye is a journey of salvation.

Early simulation, daily life.

After the chat group appeared, Bai Ye's good days were over, as he saw that everyone in the chat group was someone he knew.

No talent for ninjutsu? Then carve a bloody path with your sword!

Traveling through the world of Naruto, Yongen unexpectedly became an orphan in the Hidden Mist Village.

Without a surname, without chakra talent, unable to practice ninjutsu, and unable to even learn the most basic illusion techniques...

Fortunately, Yongen has awakened the [Proficiency System] - as long as he practices repeatedly, he can become infinitely stronger!

Swing your sword a million times and unlock the title of [Sword Saint]!

Everything in the world will be killed!

Even if one practices Chakra thousands of times without any talent, he can still forcibly upgrade to the Six Paths level!!!

With his physical skills trained to the extreme, Yongen's body even surpasses the Eight Gates of Ninjutsu, and he can shatter Susanoo with a snap of his fingers!

Under the cruel rule of the Blood Mist, he endured and grew up.

"Others practice ninjutsu, I practice swordplay."

"Others learn illusion techniques, I practice swordplay."

"Others are dating, but I'm still practicing swordplay!"

Until two years later——

"The Fourth Mizukage? One sword!"

"Akatsuki? Two swords!"

"Mei Terumi? ...Wait, what did you say? You want to marry me?"

Carrying the cultivation technique "Mysterious Origin Creation Manual," he transmigrates to Konoha in 1942 at the age of 6, becoming Uchiha Chen of the Uchiha clan. He grows up before the Third Shinobi World War, rises to prominence during the war, and hides in Konoha to cultivate immortality.

Having transmigrated to a world of advanced martial arts, Lin Ye only wanted to peacefully study at a martial arts university.

But that thing that calls itself the "Strongest Dungeon Boss System" seems to be a bit dim-witted.

It really thought Lin Ye was just a low-level cannon fodder boss!

Other people's skill tree is: Basic Fist Techniques → Fierce Tiger Fist → Ascending Dragon Fist.

Lin Ye's skill tree is:

Phase 1: [Normal Attack LV1], [Thick Skin LV1], [Charged Slam LV1]

Phase 2: [Berserk LV1], [War Stomp LV1], [Cleave LV1]

Phase 3: [Summon Minions LV1], [Intimidating Roar LV1], [Thorn Aura LV1]

...

Final Stages: [Universal Apocalypse LV99], [Doomsday Judgment LV99], [Absolute Territory LV99], [Undying Grip LV99]...

Lin Ye repeatedly emphasized that he had transmigrated to a high-level martial arts world, and that he was a human!

No, you're a goblin!

[Please abandon your illusions and prepare for battle!]

[This system will definitely make the host the strongest BOSS in this world, and will never be defeated by adventurers!]

Several years later.

When all races invaded, the demon god grinned and twisted Lin Ye's head off.

But to their astonishment, they discovered that this appeared to be only the first vial of blood from the human before them.

"Congratulations, you've removed my limiter. Next up is Phase Two!"

King Kai: It's hard for me to rub the planets with my hands, but he can rub the universe with his hands!

Beerus: Where are the mortals? This energy is even greater than mine, like a God of Destruction!

High Priest: How could you use the power of angels!

Red: Oh, so the advanced programming of cosmic particles is the power of angels!

Omni-King: Impossible! This is my power!

Hong scratched his head: "Huh? I used cells to simulate the rules. Is it difficult?

Who says Earthlings have bloodlines with upper limits? I! Red! Earthlings! I sit above all the gods!

Thirty years later, or in the more distant future, when people recall the splendor of rock music in the 90s and the splendor of Hollywood movies, will they bring up such a name, “Hugo Lancaster”, and will they She said repeatedly, “I think back then, I experienced the age when Hugo created miracles.”

On January 14, 1992, Hugo Lancaster received his first Worst Actor Award in tears at the 12th Golden Raspberry Awards, becoming the first person to come to the scene to receive the gold. The characters of the Raspberry Award have left their mark on the page of history. However, since then, Hugo has embarked on a completely different path, opening his life long enough to be recorded in the annals of history. His name is destined to become the most shining symbol in the history of music and film.

In 1993, when the rock and roll heroes came together, and in 1994 when the film masters gathered, the name of Hugo Lancaster has become one of the members that cannot be ignored.

After traveling to the martial arts world, Ning Qi was a baby at the beginning and was killed. Fortunately, he had the full level of comprehension, and he could understand everything with one thought. Creating a method was as easy as breathing and drinking water. In a dangerous situation. Inspired by the Taoist fetal breathing in the previous life, he also felt his own body, integrated the innate energy with the fetal breathing, and created the innate fetal breathing to escape the killing. Then he set foot in the martial arts. He read thousands of classics in the Sutra Pavilion to enrich his knowledge, and practiced in the Taoist Academy in a low-key manner to pursue immortality. He created a method that was unprecedented in the past and opened a path that was unimaginable for future generations. In more than ten years, he has been invincible in the world. But Ning Qi is determined to live forever. After a hard pursuit, he realized that the world is different and he cannot ascend. No hope for immortality? Ning Qi did not give up. Since he could not ascend, he would find another way to create a supreme method. The world is me, and I am the world. Continuously raise the upper limit of the world you are in, continue to grow, gather the wisdom of all beings to open up the way forward, and smelt all the ways.

Unknowingly.

The original lower world has been transformed into another fairyland by Ning Qi, and he has become the Taoist ancestor of the fairy.

...

One day.

The supreme master of the fairyland came across the world, with infinite fairy light condensed, with monstrous anger, wanting to smash the world.

"A fake fairy in the lower world dares to seize the fortune of the fairyland?"

Ning Qi, who was preaching, raised his eyes slightly, a ray of light suppressed the ages, crossed time and space, shattered the immortal body of the supreme master, and his calm voice resounded throughout the heavens and the world.

"From today on, the fairyland changes positions."
