"It's just down there." Tsunade said after bringing Guan Liyuan to a small forest... no, a forest in the Land of Sky.

Guan Liyuan closed his eyes upon hearing this, entered the natural energy perception mode, and exerted his perception to the maximum.

"Well, there are indeed a few small flying insects nearby." Guan Liyuan said and disappeared at high speed.

A moment later, he returned to the original place with two ninjas dressed in the Hidden Sky Village.

"Who are you? The Hidden Sky Village will not let you go!" The captured Sky Ninja said while trembling.

"Actually, you know who we are, right? Do you still want to hide the fact that the Hidden Sky Village is 'down there'?" Guan Liyuan said sarcastically. "

I won't..."

Before the other party could say anything to make up his mind, Guan Liyuan had already used the Phosphorus Release Chakra to make him completely fall into the illusion.

"Lead the way." Guan Liyuan said to the two Sky Ninjas whose eyes were dull.

The two of them acted in unison and walked in the same direction. Guan Liyuan, Tsunade and the other two hurriedly followed.

If it was the Great Hidden Village, it would not be so easy to interrogate them directly with illusions, because the Great Hidden Village with a complete system would plant a seal in the mind of the ninja who knew too many secrets and was not good at illusions, so that he would not reveal the secrets of the village when he was hit by an illusion.

Whether he could be interrogated later would depend on the comparison of the attack and defense level of illusions and sealing techniques of both sides...

But in the Hidden Hollow Village, there were obviously no ninjas who were proficient in spiritual sealing techniques.

After walking a few miles away, the two of them made some moves on a towering ancient tree, and then opened a portal as high as a person on the trunk!

"Is there a trick? The source of the power I sensed was at the position just now, but now it has shifted a lot." Tsunade frowned.

"No, as far as I know, the Hidden Hollow Village has discovered a 'city' that is suspected to be an ancient relic and can fly in the sky. It is now hidden underground. The source of the energy you feel should be in the center of the city, and the entrance to the underground may be at the edge of the city." Guan Liyuan speculated.

"A flying city?" Tsunade didn't seem to believe it.

"Whether it can fly or not, we will verify it ourselves later! Now let's clean it up first..."

Hearing Guan Liyuan's tone of "totally treating the underground ruins as his own", Tsunade couldn't help but roll her eyes. In the dream, Guan Liyuan liked this kind of unreasonable tone, but then she realized that this was reality and "just now" was just a dream, and she immediately became serious again.

Guan Liyuan was walking in front and didn't pay much attention to Tsunade's movements, so he didn't notice this. Instead, Shizune, who saw this scene, had a question mark on her face.

Guan Liyuan was walking in the downward passage with the flame formed by the flame chakra lighting in front, but various stone doors began to descend in the passage halfway!

"Huh? Discovered? Then force your way in... Dissolution Release: Snake Monster Passing Technique!" Guan Liyuan said and directly formed a seal to guide the dissolution chakra of the rhino dog. I

saw that around the four people, soluble acid appeared out of thin air and wrapped the four people up, and then the place where the four people stood was hollow!

If you look from a bird's eye view, the acid has formed the shape of a giant python, and Guan Liyuan and the other four are in the giant python...

"Follow!"

Guan Liyuan controlled the acid giant python forward, and the stone gates he encountered were directly melted through. Some kunai and large shurikens shot from the walls were also blocked by the outer layer of acid.

After going all the way underground, I don't know how deep I went down, and suddenly the view in front of me was clear. I saw that the underground part had been hollowed out a lot. The four people were standing on a stone material ground that was obviously different from the surrounding rock layer. There were also many buildings with human faces on the "ground", and the style was different from any ninja village!

The "roof" above had been dug out by the air ninjas, and it was not in contact with the surface. As long as there were enough earth escape ninjas, this was not an impossible task. You can see that in the center of the underground city, there is a towering tower, and the top of the tower is on the surface above...

"The source is at the tower!" Tsunade said.

There are some lighting equipment in the city, but they are all products of the modern ninja world, and they should have been installed by the air ninjas later.

Although it was a bit dark, it did not affect Guan Liyuan and others' vision...

At the same time, many air ninjas rushed towards Guan Liyuan and others from the surrounding streets.

"Hmm? This feeling is... Let's rush closer to the center!" Guan Liyuan said.

These air ninjas who could not take off in the current environment, although there were many of them, did not pose much threat to Guan Liyuan and others, and they easily advanced a lot to the central area.

"Here!" Guan Liyuan said as he broke into a stone house on the side of the road.

Then, around the stone house, the five tailed beasts were summoned!

"You guys pay attention, just block them, don't destroy the buildings here." Guan Liyuan warned.

He remembered that the main body of this "Sky City" was not very strong. Guan Liyuan, who had already regarded it as his own thing, naturally did not want it to become a scene where Ultraman fought monsters...

At the same time, Guan Liyuan launched a "psychic contact" in the direction of the central tower!

"What are you going to do? Don't you want to knock him down in one breath?" Tsunade obviously still remembered that Shennong had tricked her.

"No, he is waiting for us now. I don't know what conspiracy he is preparing for us! Although I am not afraid of him, there is no need to step into his trap..."

"It's useless to sit there?"

"Not only sitting... I have the ability to communicate with beings other than humans! This distance has allowed me to contact the existence that is the source of that power!"

"Huh? You mean the power attached to me? Be careful, the nature of this power is extremely crazy, and its source is definitely not a good thing!"

"I understand, if the negotiations break down, we can just attack again." Guan Liyuan said.

[It's really too much, saying that I am not a good thing...] A voice with a duck voice sounded in Guan Liyuan's consciousness.

At this time, in the spiritual level, Guan Liyuan was talking to a big meat worm with "Zero" written on its head.

[Then what are you?] Guan Liyuan asked.

[I am not a thing!]

[...]

[I mean... I... Anyway, I am a great existence!] Zero Tail said with a duck voice that a "great existence" should not have.

[Kurouma, Rhino... can you please pay attention to communicate with us? Let's see if this guy is your long-lost brother.]

The five tailed beasts also appeared in the chat room formed by "mind contact".

[I don't know him! I told you a long time ago that there is no "Zero Tail" among us!] Kurama said.

[Then this guy is... pretending to be a tailed beast?] Guan Liyuan asked.

[What, what impersonation! Do you think I want to? Today's idiots, none of them can recognize my greatness at all, they only know that the tailed beasts are powerful... I just have to...] Zero Tail stammered.

[Just pretend to be a tailed beast?] Guan Liyuan said for it.

Zero Tail seemed to be hit in the sore spot and didn't say anything for a long time.

[Tsk tsk, there is a "zero" on the head?]

[Is it deliberately made to make people believe that they are related to us?]

[Haha, what about "great existence". 】

【What a guy with no self-respect...】

The tailed beasts stabbed Guan Liyuan one after another through his "psychic contact".

【Ahem, what are you?】 Guan Liyuan felt that Zero Tail was about to cry.

Zero Tail, who was already unable to lift his head, now raised his head with a strong spirit and wiped off the "Zero" and said excitedly: 【I am the 'Heart of the Ninja Clan'! The 'Heart of the Ninja Clan' was opened by the second generation leader himself and perfected by the third generation leader!】

【Ninja Clan? Wait... if it's the leader of the second generation of the Ninja Clan, isn't it...】
