According to the printing method recorded on the scroll and the chakra running route, Uesugi Tsuki began to practice.

Start with the most basic sealing. Since the sealing order of each ninjutsu is different, what you need to learn most when you first practice is how to proficiently form seals according to the order.

Further down the road, the chakra is run according to the established route.

The above mentioned Sugito's current chakra intensity and the chakra control of such intensity, and the mere C-level ninjutsu did not cause him much difficulty.

After only two or three trials, Uesugi Tsuki was able to fully perform this technique.

Wei—Chen—Zi—Si.

There are only four seals, which is not difficult.

Uesugi Tetsu flew his hands and completed the seal in an instant.

At the same time, the chakra in the body has also completed a round in the established route.

In the blink of an eye, chakra surged, and a strange breath filled the whole body. Uesugi Tetsu held his right wrist with his left hand tightly, stretching his hands forward, and facing the palm of his right hand in front.

A special technique suddenly jumped out of Uesugi Tetsu's right palm, like several chains, instantly woven into a net and rushed forward.

Uesugi Tsuki was immersed in his mind, carefully felt the breath in the technique and the changes in his own chakra, and finally discovered some clues.

Combined with the feeling of using the "Spirit of Bounding and Enclosing" before, the so-called sealing technique is essentially to use its own chakra energy to condense a specific technique to seal the target.

This technique usually includes blocking energy, limiting energy, and some summoning abilities.

You can regard the technique condensed by running chakra when casting sealing techniques as a lock, and then use this lock, supplemented with other items such as scrolls, to create a blocking effect on the target.

But it is not easy to untie the lock.

The reason why Uesugi Tetsu planned to practice a variety of sealing techniques was actually that was to combine the situation of various sealing techniques to develop a technique that could unlock most of the "seal locks", thereby creating a new ninjutsu.

Counter sealing technique.

He suddenly remembered that the five elements seals that Orochimaru put on Naruto were blocked using the principle of the mutual restraint of the five elements.

Later, Jiraiya used the technique of "Five Elements to Unseal the Seal".

The opposite principle of the five elements mutual restraint between the "Five Elements Seal" and the "Five Elements Seal" is a technique formed by the force of the mutual generation of the five elements.

According to this idea, Uesugi Tsuki suddenly had a guess.

If you run chakra in a reverse direction, can you unlock the sealing technique imposed by the enemy on yourself?

Thinking of this, Uesugi Tetsu made seals with both hands, and with a "bang", a shadow clone appeared beside him.

"Accompany me to experiment." Uesugi Tetsu said.

"No problem!" Shadow clone grinned.

This is not the first time Uesugi Toru has played this boring and fun mini game.

"Ninjutsu Chakra Seal Technique!"

Uesugi Tsuki roared, and quickly formed a seal in his hand. Chakra suddenly surged, and his left hand held his right wrist. A technique instantly flew out of his palm.

Swish.

Several lines of the technique, like chains, enveloped the shadow clone in an instant, and then suddenly contracted and directly penetrated into the shadow clone's body.

"What does it feel?" Uesugi Tsuki asked.

Since the shadow clone had not been removed at this time, he could not get the relevant memories.

"Chakra can't work!" Shadow clone said in surprise.

"Can you break through with a try?" Uesugi Tetsu said again.

When the shadow clone heard this, he immediately tried to force the chakra, but his face turned red, and he still pulled... No, he still couldn't break it.

"No." Shadow clone breathed a sigh of relief, a little annoyed.

Uesugi nodded. His chakra intensity was actually the same as the chakra intensity of the shadow clone, and the number of chakra was also distributed evenly to the body and shadow clone through the shadow clone technique.

When the chakra quality and quantity of two people are the same, they cannot crush the lock formed by the sealing technique with absolute energy, and they cannot break through the seal.

This won't work, Uesugi Tsuki plans to try it out, if he goes backwards, can he unlock the lock?

"Try it again, chakra in retrograde technique, see if it works." Uesugi Tsuki said immediately.

"Okay!" Shadow clone closed his eyes and followed the running trajectory of "Chakra Seal Technique", circulating the chakra in his body in the opposite direction.

puff.

A muffled sound suddenly came.

"Has it been successful?!" Uesugi Toru was surprised, was it...

"That... no, I can't hold it in, so I fart." Shadow clone scratched her head and almost died of the community.

Uesugi: "…"

With a helpless sigh, Uesugi Tsubaki turned the Shadow clone into a real fart.

Bang.

The shadow clone disappeared.

"I wouldn't have eaten that much if I had known it... hiccup."

After removing the Shadow Clan Technique, Uesugi Tsubasa immediately gained the memory of the Shadow Clan and experienced it in person the feeling of being sealed just now.

Chakra was locked tightly, and it was really not good at all.

After obtaining the memory of the Shadow Cluster, Uesugi Tsuki calmed down and carefully recalled the different chakra changes when sealed and when sealed.

And the experience of the shadow clone just now, when she was trying to untie the seal lock while going backwards.

After some thought, Uesugi Tsuki shook his head secretly and said self-deprecatingly: "It's not that easy..."

Each different sealing technique has its own different sealing locks. It is basically unlikely to find a "master key" to unlock all sealing techniques.

Just like the "Five Elements Seal" used to impose the principle of mutual restraint of the five elements, the "Five Elements Seal" must be used to impose the "Five Elements Seal" to unlock it using the principle of mutual generation of the five elements.

Each lock has its own exclusive key.

Such as the sealing technique that possesses the power of summoning, the sealing of corpses and ghosts, the sealing of spirits, etc. If you want to untie, you must summon the contract with the God of Death or other spiritual objects, first terminate the contract, and then untie the seal.

However, the ninja world is so magical that even things like chakra can be derived. Maybe there is really a "master key" to restrain all sealing techniques.

But with Uesugi Tsuki's strength and insight, this key is at least 108,000 miles away from him.

Save the scroll and Uesugi Tsubaki temporarily puts the research on sealing techniques aside.

This attempt was not without results.

First of all, he learned a C-level sealing technique and did not mention it. Although he could not study the "counter-sealing technique" he imagined to untie most seals, at least, he also mastered the essence of sealing technique.

In other words, at the level of some basic sealing techniques, he can break through the seal lock through his ever-growing chakra strength and achieve the effect of unsealing it.
