With direction, it's much easier to guess or research. Yichen and Atsumi Qiunai thought about the idea of time and space, and many structures that were originally incomprehensible became clear at once.

After half a day of research and half guessing, the effect of these runes was immediately guessed by Yichen and Wu Mei Qiunai. At the same time, the effect of this seal was also guessed by the two.

As for Riori Uzumaki and Ishinori Jingqing, they didn't understand at all, so they went back early to continue their training.

Yichen guessed that the inside of the seal should be a passage connecting to another dimension, and the purpose of the seal was to isolate the connection between the other dimension and the ninja world.

What was on the other end of the passage, Yichen was very curious, and at this time, Yichen was a little hesitant to break this seal.

What if this seal is broken and a world-destroying monster comes out from the other end?

However, after thinking about it, Yichen still decided to break the seal.

If this was in the Land of Earth, Yichen would definitely think twice, but this is in the Land of Vortex, on the other side of the Land of Fire, even if there is danger, there are Konoha and Mist Ninja Village, and Cloud Ninja Village in front.

Among the five great powers, the land country is the farthest away from the vortex country.

Thinking of this, Yichen divided into two shadow clones, one shadow clone stayed in the air with three disciples and the main body, and if something happened, he immediately ran away.

Another shadow clone is on the ground ready to use ninjutsu to interfere with possible enemies, ready to buy time for the main body to escape.

After getting ready, Yichen began to perform ninjutsu: the technique of light escape and original realm stripping.

The blue light flashed, and the seal was directly pierced through a huge hole, and the rest of the seal flickered a few times before all collapsed.

Losing the shade of the seal, the bottom of the crater appears as a black hole.

Seeing this scene, Yichen's main body activated the chakra and was ready to flee at any time, while the shadow clone below began to slowly approach the black hole.

The process was not long, and after a while, the shadow clone arrived at the entrance of the cave, and when he saw that nothing came out, the shadow clone jumped in.

Soon, the shadow clone that entered it dissipated, and feeling that the memory of the shadow clone was transmitted back so quickly, Yichen was startled at first, could it be that there was danger at the entrance of the black hole.

was about to run away, but the memory of the shadow clone stopped Yichen.

That feeling is, gravity? To be precise, it was super gravity, and the shadow clone couldn't stand on its feet after entering it, and smashed it directly against the ground.

Then the shadow clone dissipated.

Could it be that inside this seal is a space with super gravity?

Wait, gravity space, could it be that this is the gravity space in those different spaces that can be shuttled through Huangquan Hirazaka?

Thinking of this, Yichen split up a shadow clone again, and this time the shadow clone performed the light and heavy rock technique with all his might. The shadow clone that used the Light and Heavy Rock Technique flew into the black hole according to Yichen's request.

This time, the shadow clone did not dissipate so quickly, but it took a long time before the shadow clone itself took the initiative to disband.

"It's gravity space." How did the Vortex Clan manage to locate even a different space?

After the alarm was lifted, Yichen planned to go down to see it for himself.

However, although there are no other people inside, the gravitational pull of the overweight is dangerous enough, and even if you want to go inside, you have to make some preparations.

Now this state is definitely not good, several times out of the shadow clone, Yichen's chakra amount is obviously not enough, and he has been studying the seal for many days, Yichen's current spirit is not good.

It's better to rest for the night.

The next day, the state returned to the best Yichen, first entered the immortal mode, and then decisively flew into the black hole.

The moment he entered the black hole, Yichen felt a huge gravitational pull.

At this time, Yichen performed the light and heavy rock technique, but he still couldn't offset the effect of super gravity, and quickly fell down.

However, Yichen, who had been prepared for a long time, did not panic, and tried to adjust the posture of his body in the air, which Yichen was good at.

Soon the dust fell to the ground.

Although Yichen has been adjusting his body, he is still lying on his stomach after landing.

However, Yichen has the blessing of the immortal mode at this time, and in the immortal mode, Yichen's power is far greater than usual.

Struggling to get up from the ground, Yichen tried to jump and found it too difficult for himself. If you want to straighten your legs after bending, you have to overcome gravity a little bit, and how to jump.

Immortal law - earth escape - earth flow wall.

The gravity space can perform ninjutsu, and Yichen had confirmed it through the shadow clone the day before, otherwise Yichen would not dare to come in.

Yichen cast a wall of earth flow under his feet and successfully pushed himself up.

However, due to the limitations of super gravity, Yichen's earth flow wall blessed by immortal magic is not too high. This level is far from reaching the effect of the A-level ninjutsu earth flow city wall.

So Yichen continued to cast the earth flow wall, and after casting more than a dozen earth flow walls in a row, Yichen finally raised the ground to the vicinity of the entrance.

Because it was the first time the main body came in, he was afraid that the disciples outside would be in a hurry, so Yichen did not stay inside for long, but immediately walked in.

Seeing Yichen come out, the three little ones all breathed a sigh of relief. Seeing this, Yichen smiled slightly, and after a few words of instruction to the three of them, he entered the gravity space again.

This space is a treasure for Yichen, and this kind of continuous, gravitational place is too rare. It's especially easy for Yichen to practice gravity-related ninjutsu here.

The gravitational environment of the ninja world is not felt by the people who live in it, and unless it falls from a high altitude, the feeling of weightlessness will make people feel something.

And in this space, Yichen can feel a huge gravity at all times, as if someone is pointing at Yichen's gravitational ninjutsu, and it is also a demonstrative pointer. As long as Yichen carefully understands the gravity that is different from the outside world, he can improve his proficiency in gravitational ninjutsu.

After practicing the Light and Heavy Rock Technique and the Heavy Rock Technique, Yichen began to practice two new S-level ninjutsu when he felt that his proficiency in these two ninjutsu had increased to a limit, and Yichen began to practice two new S-level ninjutsu: the Super Light and Heavy Rock Technique, and the Super Heavy Rock Technique.

The process is very smooth, these two S-level ninjutsu are an upgraded version of the light and heavy rock technique and the heavy rock technique, and learning in this environment seems to be a matter of course.

Then there is the Vientiane Celestial Attraction and the Celestial Signage of the Shinra. These two ninjutsu are a little more difficult to learn, because the previous ninjutsu were gravity ninjutsu, which fit the environment incomparably, but these two ninjutsu are pure gravitational ninjutsu.

Gravity is related to gravity, but it is not exactly the same.

However, Yichen's harvest is still very large, Vientiane Tianyin, this Yichen's ninjutsu that was originally used well, has now been improved in terms of both power and casting distance.

And the biggest gain is the Shinra Heavenly Sign, the ninjutsu of the Shinra Celestial Sign, although the level is S-level, but Yichen is rarely used. There is no other reason, because the power is too small, and when he first learned it, the HRE Tianzheng only had the power of C-level ninjutsu.

Yichen's use of the Shinra Heavenly Signs is all used to speed up the kunwu.

Later, Yichen's gravitational ninjutsu has not made much progress, that is, last year, Yichen calmed down and did not go out of the village, and when sorting out various ninjutsu, he improved a little.

This time, Yichen can be regarded as making a qualitative leap in the Shenluo Heavenly Sign.

Yichen felt that he was now using the Shenluo Heavenly Sign, and his slight strength had surpassed most B-level ninjutsu, and he was about to reach A-level ninjutsu.

It's no wonder that Nagato likes to use the Shinra Celestial Expedition against the enemy, this is really too convenient and practical.

There is no need to seal, the Shinra Heavenly Sign, if it is powerful, then why use other ninjutsu?

For example, Yichen has been using porcelain for a while, but it is really because porcelain is easy to use, and it is too easy to deal with the enemy with the ever-changing porcelain escape.

In the gravity space, after practicing ninjutsu one by one, Yichen gained a lot.

Of course, in this space, the Weight Rock Technique Benefit Dust did not dare to use it on himself, and only dared to experiment with the objects around him.

This cultivation process was very fast, and in just three days, Yichen was able to fly in this space with the Super Light and Heavy Rock Technique.

At this point, Yichen stopped practicing and chose to leave directly.

Flying out of this space, Yichen covered the black hole again, and then used Earth Escape again to backfill the deep pit. Although Yichen's simple and crude handling method was not comparable to the Vortex Clan's sealing technique, it was better than nothing.

After dealing with it, Yichen left Vortex Village with his three disciples.

On the way back, Yichen also took the scroll hidden by the intelligence ninja. It can be regarded as the completion of the mission of coming to the country of vortex this time.

Because the delay in Vortex Nest Village was too long, on the way back, the four Yichen chose to fly.

Because of the gains from cultivating gravity in gravity space, Yichen's flight speed when he performed the Light and Heavy Rock Technique was also much faster.

Yichen didn't forget the agreement with the sharks, so he didn't go back to Iwa Ninja Village directly, but came to the place where the sharks gathered before.

Seeing that Yichen and his party finally returned, the big shark Yuko was very happy, and it immediately greeted him and had an exchange with Shi Zejingqing.

Then Yichen took hundreds of sharks and headed in the direction of the Moon Country.

Yichen has two options to bring the sharks back to the coast of the Land Country, one is to surround the Land of Thunder from the outside, this road is all at sea, but it takes too long.

The other path is through the Land of the Moon. This path would have been impossible for schools of sharks, as the seas to the left and right of the Moon Country were not connected.

But Yichen said that this is simple, and if you can't swim over, then fly over.

Flying back to the land with these hundreds of sharks directly will definitely exhaust Yichen to death, but if it is only across the country of one month, then Yichen said that it will be easy.

However, Yichen has never been good at chakra, so he is in line with the idea of saving a little if he can. Yichen took advantage of the night to let the sharks swim inland along the river of the Moon Country first, and when they couldn't swim anymore, they would use the light and heavy rock technique to send the sharks to the sea on the other side one by one.

Although Yichen's Light and Heavy Rock Technique had improved a lot, he was still tired enough.

Luckily, all the sharks were finally in place before dawn.
