The Secret of the Eye of Heaven

The biggest gain from this underground ruin was that the Eye of Heaven advanced to the fourth stage, and the quality and quantity of Chakra also rose from the level of an elite Jonin to that of Kage Level ninja. This is a very significant achievement. Originally, with Issui's physique, it would have taken another two years for the quality of his Chakra to fully catch up. However, thanks to the life energy modification from the Gelel Vein, Issui's body has been greatly strengthened. Even when facing Kage Level ninjas specializing in Taijutsu, his Taijutsu is not inferior. With his physical strength in place, all that remains is close-combat experience.

After absorbing the Gelel Vein, Issui did not leave. Instead, he recalled the information he had obtained from the ruins of the Heaven Village. Among them was a secret scroll that could only be opened when the Eye of Heaven advanced to the fourth stage. It was said that it contained the true secret of the Eye of Heaven.

Actually, after leaving the ruins of the Heaven Village last time, I learned from the secret history of the Heaven Clan that no one has ever been able to open the fourth stage of the Eye of Heaven. Only the fallen Heavenly God, the creator of the Eye of Heaven, who was the ancestral god of the Heaven Clan, was able to open the fourth stage. The reason why no one has been able to open it is because the fourth stage requires the absorption of a very large amount of energy. Issui came to the underground ruins before in order to use the life energy of the Gelel Vein to advance to the Eye of Heaven, and fortunately he succeeded.

Why does the fourth stage require so much energy? The main reason is that the creation of the Sumeru World requires a great deal of energy. A simple space would be fine, but the Sumeru Realm is a world full of life. Only the life energy of the Gelel Vein can allow the Eye of Heaven to absorb enough life energy to create a world, even though this world is still in its infancy.

Issui carefully took out the secret scroll, but when he unfolded it, there was nothing there. To make the words appear on it, one needed to activate the fourth stage of the Eye of Heaven to see them.

"Eye of Heaven: Dust!"

A vertical eye has appeared on Issui's forehead. The eyeball of this vertical eye is golden, and it flashes with golden light from time to time. In fact, this light is the hidden ability of the Eye of Heaven when it advances to the Dust stage. It can see through all the things such as concealment, Genjutsu, and barrier. It is like a divine artifact that is constantly scouting.

Golden Vertical Eyes' attention shifted to the scroll, Issui Shui read out the words one by one, "The Eye of Heaven, also known as the Demon God Eye, is not of this world's bloodline, but comes from another world. It is a Kekkei Genkai ability born from the combination of the highest-level magical source of the abyss and the powerful will of radiance. Beyond this world, there exists another world. The Demon God who created the Eye of Heaven was a god from that other world. He discovered this world and, according to its laws, compressed his own power to the extreme, forming a Kekkei Genkai eye, and thus the Heaven Clan came into being."

The Demon God prophesied that the two worlds would merge at some point in the future to form a new world, and the two different cultivation systems would collide. As the two energies gradually increased, the integration would proceed faster and faster.

In the two ancient worlds, many Demon God disappeared for unknown reasons. Whether they died or vanished, there were no signs or warnings. The Demon God who integrated the powers of gods and demons became the last one to die. Before his death, he discovered the secrets of the two worlds and allowed his descendants to settle in this world.

Please don't be surprised if you see this; this is the last piece of information I've recorded. If you've already signed the contract with the Flying Dragon Clan, then I can tell you that dragons are creatures from another world. I lured them to this world's underground realm using Secret Technique. Unfortunately, an accident occurred when I was relocating the Flying Dragon Clan here, causing the two worlds to attract and merge. Abyssal Demons from the other world also broke into the underground, attempting to invade the surface of this world. However, I signed a contract with the Flying Dragon Clan, and they will protect the underground realm of this world.

When the two worlds merge, war will break out between them due to their differing beliefs. The people of my original world are far more powerful than those of this world. The powerful beings in that world are not humans, but magical beasts. I hope that the people of that world will not be wiped out by those magical beasts. The reason I migrated to this world is because the leader of the magical beasts in that world is even more powerful than our human gods.

In order to prevent the humans of both worlds from being wiped out by monsters in the future, I integrated the power of the Demon Clan with the power of the God Clan. The reason I possessed the power of the Demon Clan race was that I pretended to submit to those monsters. With the integration of the two powers, I created this bloodline ability, which I call the Bloodline of Heaven.

Although I created this powerful bloodline, the leaders of the magical beasts discovered it and hunted me down. In the end, I led the Flying Dragon Clan to escape into this world. However, the Abyssal Demons, also invaded the underground world of this world.

Alright, my time is running out. You've learned some secrets from this, haven't you? There's a magic circle I've recorded here that can connect two worlds. Of course, if the two worlds have already been integrated, then it's not necessary. If not, that's great! You can go to that world first to gather information and make some preparations before the two worlds merge.

The Demon God Argus* Philia.

Issui banged his head a few times. Was he dreaming? What kind of theory was this? There was some other world outside the Hokage World? Were you kidding me? I thought that after I wiped out Madara Uchiha and Obito Uchiha's conspiracy and unified the ninja world, I could finally enjoy a peaceful life with my wives. I never imagined that there was an even stronger enemy waiting for me—no, a group of even stronger enemies! Were you kidding me?

Is this the Hokage World? It's definitely not Earth. If it were Earth, people would have discovered another Earth and migrated there long ago. No matter how powerful the monsters are, they would all be blown away by steel.

I tried to endure it, but I just couldn't. I thought my understanding of the Hokage World would make me a Legendary figure, and I could live a wonderful idyllic life with several beautiful women. But the blow came too fast.

Could it be that my arrival in this world caused some changes? First, there was the Kekkei Genkai Eye of Heaven, which didn't appear in Hokage; then the Flying Dragon Clan; and finally, the demonic beast army from another world. Now I finally believe in the saying: God gives you something, but He will inevitably take something away from you. There's no such thing as a free lunch.

Are you kidding me? This is a huge joke! You've given me the Eye of Heaven and Flying Dragon Clan, and now you're making me lead the people of two worlds against an army of monsters? Who can be sure this isn't some chivalrous knight-errant story where the hero saves the world?

This is utter nonsense! I'd rather not have looked at this scroll at all. If I hadn't looked at it, I wouldn't have felt any pressure. But looking at this thing has put me under so much pressure!

Am I the savior of these two worlds? Is that why I possess so many abnormal abilities? That's a really twisted thought!

Sigh, forget it, accept your fate. I should still prepare and go to that world to gather intelligence and information. Akatsuki, Madara Uchiha, and Obito Uchiha aren't the biggest problems anymore. A famous saying from my past life is true: you never know what the future holds. With great power comes great responsibility.

Who knows what will happen in the other world, or how long it will take? I should go back to the village first and find a reason to ask Tsunade for a long leave.

Issui packing his things, cleaning his clothes, and eating a few rice balls, Yishui set off. From then on, the Phantom Underground Ruins no longer had the Gelel Vein, and Naruto and his friends' mission was simply to eliminate the evil Haido.

Two days later, Issui appeared at the border of the Land of Fire, then suddenly stopped, no longer continuing his journey. Someone had been chasing him for a whole day and night. In the Land of Wind, he couldn't make a move. Sunagakure and Konoha were currently allies, and it wouldn't be good to start a fight in the Land of Wind. If Tsunade, that violent maniac, lost her temper, she could easily punch him.

"Come out. Although you've hidden yourself well, I'm not stupid. You've been chasing me for so long, don't you need to rest? Your breathing has gotten heavy."

Issui turned around and looked behind a tree, saying.

"Hmph, I didn't expect you to have found out so early. What an unlovable fellow. May I ask, what are you doing in the Land of Wind, an elite Jonin of Konoha? What are you plotting?"

Temari emerged from the shadows of the tree, took out the fan from her back, and instantly unfolded it— the Three Stars!

"Yo, yo, what are you doing? Want to fight me? Well then, I'd be happy to give you some pointers."

Issui said with a wicked smile, Shuriken his hand.

"..."

When Temari saw him draw his Shuriken, her face was covered in cold sweat, and her fingers gripped her fan tightly, ready to launch a storm of attacks at any moment.

"Oh, your reaction is quite good. What are you afraid of, beautiful? Afraid I'll kill you? Life is so fragile..."

Suddenly, Issui appeared behind Temari, his Shuriken lightly touching her delicate neck.

"What... what are you doing? Are you trying to kill me? This is breaking the alliance agreement!"

Temari finally couldn't take it anymore and screamed, "Is he going to kill me?"

"Uh, you're overreacting. This isn't funny."

Issui Temari's shouting and yelling, Ikki had no choice but to put away the Shuriken his hand. "I just wanted to play with you a little. You're such a coward. If I let her keep shouting like this, it might attract the ninjas guarding the border between the two countries. It wouldn't be surprising if something bad happened."

(Your words are like farts. Your life is in someone else's hands. One moment you're in heaven, the next you're in hell. Who wouldn't be nervous?)

"..."

Hearing what Issui said, Temari gradually relaxed. What an annoying man, even though he's my ideal type.

"Alright, I'm just traveling in the Land of Wind. I haven't done anything to harm Sunagakure. I'm leaving now. Don't follow me. I generally don't kill women, especially beautiful ones." Issui patted Temari's chubby Temari and disappeared using Body Flicker Technique.

Feeling her face being Issui like a pet, she finally snapped, "You bastard, try and run! I'm going to die today..."

The enormous roar startled the birds in the forest, which flapped their wings and flew into the sky.
