Black Naruto: Shadow Moon

After a long interstellar journey, Otsutsuki Momoshiki, Kinshiki, and Urashiki finally arrived at the Ninja Realm and reunited with Otsutsuki Isshiki.

Their goal is clear - to replant the sacred tree, harvest chakra fruits, and plunder the resources of the ninja world.

However, just as they began to investigate the movements of the ninja world, they were discovered by Uchiha Kagezuki.

Yingyue didn't wait for them to launch an attack, but took the initiative to attack first.

He stood high in the air, looking down at the four foreign Otsutsuki people, and the vast chakra from his body emanated like a tide.

Momoshiki's pupils shrank, and he stepped forward with a sneer: "Are you the Uchiha Kagezuki who made Isshiki flee in embarrassment? You are indeed very impressive."

"Stop talking nonsense," Yingyue's eyes were cold, and there was a cold light flashing in his eyes of reincarnation, "I will not allow anyone to come to the ninja world to plant the sacred tree and destroy the peace."

Otsutsuki Momoshiki confronted Shadow Moon and said arrogantly: "We, the Otsutsuki clan, have conquered countless planets, and no natives have ever been able to stop us. You are just a strong ant, Shadow Moon!"

As Momoshiki finished his words, he, Kinshiki, Urashiki, and Ōtsutsuki Isshiki, who had recovered some of his strength, stood still in unison, and the powerful chakra gathered into four astonishing energy waves.

The four members of the Otsutsuki clan united together, filled with murderous intent. Four strands of chakra rose up, creating a huge wave on the battlefield.

Facing the joint attack of four people, Yingyue was not afraid at all.

The Nine-magatama Samsara Eye in his eyes flashed with mysterious light, and with a raise of his hand he summoned the complete form of Susanoo, like a giant god of war standing between heaven and earth.

Yingyue said calmly: "You will eventually understand that the ninja world is not a place where you can do whatever you want."

A fierce battle broke out instantly. Yingyue controlled Susanoo and wielded the giant sword to fight Momoshiki, while Momoshiki wielded his own power to form a huge energy shield with rotating chakra, blocking Yingyue's fierce attack.

At the same time, Jin Shi turned into a golden light and attacked Yingyue, with huge energy condensed in his fists and hit Yingyue directly.

However, Yingyue snorted coldly, and the Rinnegan's pupil technique was activated. Time seemed to stop instantly, and Yingyue fought back with lightning speed. The Rinnegan's "Heaven's Mind" folded the space, making Jinshi's attack invalid. In a flash, Yingyue hit Jinshi from the side, blasting him back hundreds of meters.

As the fierce battle continued, Yingyue always suppressed the four people with his powerful fighting skills and amazing reincarnation eye technique.

However, facing these four powerful enemies, Yingyue's strength far exceeded their expectations.

Yingyue not only masters extremely powerful chakra, but also possesses absolute control over space and extraordinary combat experience.

The combined attacks of Otsutsuki Momoshiki, Kinshiki and Urashiki were almost ineffective against Shadow Moon.

Yingyue easily fought against four people alone, and with his powerful space-slashing skills, he neutralized their attacks one by one.

After several exchanges, Yingyue began to take the initiative.

He first used the space distortion in Ame-no-Myou to bounce back the attacks of the four people, forcing them into a passive situation.

Then, Yingyue used his "Space Slash" to quickly break the cooperation between the four people, and defeated them one by one with his absolute speed and strength.

After Momoshiki was hit by the Space Slash, Shadow Moon quickly absorbed her chakra and suppressed his power to below the Six Paths level; Kinshiki and Urashiki were unable to escape and were directly decomposed by Shadow Moon's Space Slash with most of their power.

The battle was over, and the four men fell to the ground, their chakras drained, their bodies weak and unable to move.

Yingyue stood in front of them and said coldly: "The Otsutsuki clan is no more than this."

Otsutsuki Momoshiki stared at Yingyue, his eyes full of reluctance and anger: "Do you think this is the end? The power of our Otsutsuki clan is spread across the starry sky. Even if we lose here, more people will come--"

Yingyue's expression remained unchanged, but her eyes revealed a coldness that looked down upon the starry sky: "Then I will wait for them to arrive and defeat them myself."

Then, Yingyue used the Rinnegan to forcibly control the minds of the four people and sealed them in a special prison in the ninja world.

Afterwards, Yingyue used his eye technique to deeply explore the memories of the four people, and grasped the detailed location of the planet where the Otsutsuki clan was located as well as related information.

Yingyue learned that the Otsutsuki clan's planet was located deep in the distant interstellar space, far beyond the imagination of the ninja world.

This planet has powerful chakra resources and is the source of the Otsutsuki family's reproduction and survival.

Although the current strength of the ninja world is enough to suppress them, Yingyue knows that this ancient interstellar race may be hiding enormous power, and perhaps there are more unimaginable strong people on its home planet.

The Otsutsuki clan is not only powerful in combat, but also a predatory race with an interstellar civilization. They plunder planets rich in natural energy in the universe, plant sacred trees, and strengthen themselves with chakra fruits.

Such plundering behavior, just like the "Dark Forest" theory that Yingyue saw in his previous life's work "The Three-Body Problem", is full of cruel laws of survival.

Yingyue is well aware that there is fierce competition among interstellar civilizations in the universe, and the "Dark Forest Theory" in "The Three-Body Problem" is the key to resolving interstellar threats.

The core of this theory is that every interstellar civilization must hide its location, because any civilization that is exposed will be destroyed due to the risk of "chain of suspicion" and "technological explosion".

To avoid being annihilated by a hostile civilization, the only option is to maintain mutual deterrence and utilize information asymmetry to achieve relative security.

A complete plan gradually formed in Yingyue's mind - he would use the coordinates of the Otsutsuki clan's home planet to establish a mutual destruction deterrence mechanism to ensure the safety of the ninja world.

This plan will be named the Dark Forest Plan.

Yingyue decided to hand over this plan to the Science Department of the Ninja World, with Orochimaru leading the research and implementation.

Yingyue personally found Orochimaru and conveyed his ideas to him in detail.

“Orochimaru, although the Ninja World currently has the ability to resist the Ōtsutsuki clan, we cannot be sure of their true strength.

It is not feasible to rely on the power of the ninja world alone to fight against an interstellar predatory race. "Yingyue's eyes were deep and cold, "I plan to adopt a new strategy, borrowing the method of cosmic broadcasting to make the location of their home planet public. This method is like exposing them to the dark forest of the universe."

After hearing Yingyue's plan, Orochimaru's eyes flashed with surprise.

He had never seen Shadow Moon plan an interstellar deterrence strategy so decisively and calmly.

The core idea of ​​the Dark Forest Theory is an extreme chain of suspicion, which requires every civilization in the universe to remain silent to avoid a catastrophic disaster.

Yingyue intends to use this theory to threaten the Otsutsuki clan by "exposure" so that they dare not act rashly.
