The black tail thorn was piercing with cold light, like a sharp blade coming toward her face, but Tsunade had no time to dodge.

At the critical moment, the golden chain hit the black tail, causing a gap of a few tenths of a second.

Tsunade used her legs to exert force, moved out of thin air to avoid the incoming tail stab, and smashed down the mace in her hand.

The air was violently separated, and the stick shadow carried strong winds and hit the left claw of the spiny tail, and the shock wave tore the earth apart inch by inch.

When the two collided, the air waves lifted up the surrounding land, revealing the moist soil underneath.

Several golden chains came in an attempt to wrap up and control the Spinytail, but were easily cut off by its pincers.

The large soybean eyes of the Spinytail were full of coldness, and it shot its venomous tail sting at Tsunade, who was directly knocked away by the mace.

Tsunade stepped on it, a large crater suddenly appeared in the ground, and the carapace of the spiny tail insect broke apart inch by inch.

The cut golden chain struck again to create a gap, and Tsunade knocked down the mace in her hand.

The upper half of its body exploded directly, green blood flowed all over the place, and the flesh and blood were so messed up that it was too horrible to look at.

The two of them cooperated in a tacit understanding, simple and rough.

Uzumaki Naha skillfully dug out milky white crystals from the rotten meat.

"Let's go back to the village." Tsunade said. The Zerg's move in pairs made her feel a little uncomfortable.

It's okay if it's just an exception. If all the Zerg begin to appear in pairs, it means they are about to start breeding.

"Teacher, you are bleeding." Uzumaki Naha said worriedly.

"It's okay, I was just scratched by the flying armor." Tsunade waved her hand and replied nonchalantly.

Dark red blood flowed from the snow-white forearm, and there seemed to be a few green filaments squirming inside the blood, which looked extremely strange.

…………

Konoha Village, the land of the Uchiha clan.

Runyu was lying on an old rattan chair. It was just a very ordinary rattan weaving, but it had been with Runyu for nine years. Now it was approaching the limit of use.

It has been nine years since he came to this world. Even though he is strong enough, he still cannot change so many tragedies.

On the contrary, the ninja world is gradually heading towards a collapse that is difficult for him to face, and the Zerg descends.

Also, who the hell is Marine Marshal Luffy?

Next to him lay Uchiha Fugaku. Over the past few years, Fugaku's body had grown taller and taller, reaching almost 1.9 meters tall.

"Brother..." Runyu said.

"What's wrong?" Uchiha Fugaku quickly opened his eyes and asked. Runyu usually called him Fugaku, but he would only call him brother when it was very important.

"The Zerg core is not a good thing, you must not absorb it." Runyu solemnly warned.

"Did you find anything?" Uchiha Fugaku asked.

"I haven't found any. I just feel that any power that is easily obtained must have unknown hidden dangers." Runyu said frankly.

Although he is very powerful, he is not a god who cannot make all the plans, nor can he know everything.

He also searched for Zerg intelligence in the system space, but did not get any information. This also made him understand that Goldfinger also had this limit.

"I promise you will not touch the core of the Zerg." Uchiha Fugaku promised.

He believed that with his talent, he would be able to reach the fourth level of the Seven Exercises sooner or later.

On the other hand, Tsunade brought back the Zerg corpses, and after analysis by Orochimaru, they were indeed one male and one female. It is very likely that the Zerg would begin to multiply in the ninja world.

That afternoon, Uchiha Madara and Runyu met, but it was not just the two of them but also Uchiha Naizumi and Senju Hashirama.

Regarding the Zerg issue, the two had a very serious conversation.

"I can probably guess what the Zerg are planning."

Runyu spoke first.

Uchiha Madara held the tea in his hand and motioned Runyu to continue speaking with his eyes.

"Raising Gu."

"Raising Gu?"

"Select a certain number of Zerg and throw them into a certain world, where they will fight freely and eventually cultivate the strongest ones. Su Wan is basically like a leader and a referee who maintains fairness."

Hearing this, Uchiha Madara fell into silence while sipping the tea.

"The attack on the Fire City should be to collect energy for her to condense her transformed body." Runyu continued her analysis.

"When the fixed channel is opened, those who comply will live, and those who go against will die."

Uchiha Madara was holding tea, and the steam in the tea cup was rising. He was just silent. Senju Hashirama opened his mouth several times to speak, but chose to shut up.

"Run Yujun, which path will you choose?"

"Rebel."

"Is there no need to think about it at all?" Uchiha asked.

"I have always been a rebel, not to mention that she killed Nonoyu." Runyu said without hesitation, with no anger or hatred in his voice.

"Just for a girl? As far as I know you don't actually love her that much." Uchiha Madara stared into Runyu's eyes.

Senju Hashirama breathed out in boredom. He suddenly regretted leaving Uzumaki Mito and following him.

"But she is still mine, so it is only right that I kill a few Zerg to avenge her." Runyu said sternly.

"A little bit? A hundred million bits is about the same." Uchiha Madara thought in his mind that this conversation was over, and Runyu stood up to leave.

Runyu was walking on the streets of Konoha. Many wooden houses were being renovated, and thick steel plates were driven into the foundations to form secret rooms.

In an atmosphere where they didn't know which day the Zerg would invade Konoha, only a house made of steel could give them a sense of security.

Runyu traveled outside the Hatake clan and used the eyes of his soul to see Hatake Kakashi playing beside his mother from a distance.

It was obviously a very happy thing, but there was not much smile on his face. His father had not been home for a month.

In his memory, the image of his father was always dusty. Every time he came home, he would only stay for a day and then leave.

Hatake Sakumo was worthy of his status as a ninja and his status, but he was only sorry for his wife and Kakashi.

Runyu clapped her hands gently, and Bai Jue emerged from the ground and waited quietly for instructions.

"Find a reason to recall Akai Mitsuki and Hatake Sakumo." Runyu said softly.

"As commanded."

After that conversation, Runyu and Madara Uchiha were trapped in Konoha, while the others formed a team and left the village to hunt.

Among them, Hatake Sakumo and Akai Mizuki are in a group. The two of them have similar fighting styles and have a tacit understanding of cooperation.

…………

In the blink of an eye...one year has passed.

Konoha thirty-five years, middle.

After Akai Mitsuki and Hatake Sakumo returned, Runyu personally guided them in their training. Of course, his guidance method was only a very simple battle.

Hatake Sakumo joined forces with Akai Mitsuki to fight him, and during the discussion, the two of them understood the true meaning of Dao swordsmanship.

The most important thing is that he doesn't know how to teach it... he can only choose to keep fighting.

A year of intermittent training has made Hatake Sakumo's strength close to the true king level, which is the pinnacle of the transformation level.

Of course, the Zerg core also played a big role in this. They always increased Hatake Sakumo's physical strength until he reached the peak of the transformation stage.

Mitsuki Akai is relatively weak, barely reaching the fifth stage of transformation.

Today, several years after the arrival of the Zerg, the ninja world has reorganized its power system.

They are: genin, chunin, jounin, shadow level, shadow top, super shadow, half-step six paths, and six paths level.

The original special jounin levels were cancelled, the classification above the shadow level was refined, and five more levels were added to the original jounin to expand the upper limit.

Probably the shadow level corresponds to the Zerg that has transformed once or twice. The shadow peak corresponds to the Zerg that has transformed three to four times. The super shadow corresponds to the Zerg that has transformed from five to six times. The half-step six paths correspond to the Zerg that has transformed seven, eight, or nine times.

.

Currently, apart from the True King level, the strongest ones are the Third Raikage and Hatake Sakumo.

The former is due to the Zerg core absorbing more, and the latter is due to Runyu's training.

Last year, the third generation of Thunder Shadow was transferred to Ai, and then left the Kingdom of Thunder and began to practice deep in the territory occupied by the Zerg.

Except for the five major foreign countries, other countries have basically fallen, including the Kingdom of Ghosts, the Kingdom of Snow, the Kingdom of Sichuan, the Kingdom of Grass, etc., and have become the territories of the Zerg.

In just two years, through Runyu's exploration in the Kingdom of Grass and the Kingdom of Takino around the Kingdom of Fire, no fewer than twenty top-level transformation-level Zerg species have been born.

This level of strength can easily crush the high-level combat power of the Ninja Federation. Coupled with the Zerg domain, the connections between countries have been basically cut off, and the Ninja Federation has fallen into the embarrassing situation of existing in name only.

In this year, with the passing of Tsunade and Namikaze Minato, the older generation of strong men moved away from the core of power and began to focus on their strength.

In the training ground.
