A certain scientific Naruto

Although he was going to the front line, Yuyi basically went into battle lightly.

He had nothing to take with him.

First, he added some ninja tools, including kunai, shuriken and so on.

Second, he brought a bag of military food pills, which is a necessary medicine for killing and arson while traveling at home.

Thirdly, he bought a black cloak. This is not for the sake of being cool, because on the battlefield, being able to hide his hands is very important for a ninja. Most of the time, the first action of a ninja's attack is It is the knot seal, if you can hide your hands, you can hide your offensive motives to a certain extent.

Fourth, he prepared a white mask for himself. This has nothing to do with Anbu. He does not live like an Anbu ninja, but when he thinks it is necessary, a ninja should hide his face.Hatake Kakashi is particularly good at this, and the ninjas in the same village don't even know what he looks like.

One morning, the group of about 40 people began to leave Konoha and move towards the front line of Yasa Gakken.

From the daily scale of ninja movement, the scale of 40 people is large enough. After all, most of the time, ninjas are carried out in teams of four.

Because of the presence of weak medical ninjas, this team did not move fast. It took almost six days for them to reach the border of the Land of Fire.

"Master Kushina, next we have to raise the level of vigilance. From the geographical point of view, we have already entered the war zone, and we may encounter a small group of sand ninjas that infiltrate at any time."

In the evening of this day, when the team was busy setting up camp, the leader of Anbu approached Kushina and reminded him.

Kushina nodded and didn't say anything. Don't think she knows nothing about war just because she is so careless. In fact, she personally experienced the country's extermination incident when she was young. For She knows the cruelty of war clearly.

At this time, they were still 250 kilometers away from their destination, Konoha Frontline Headquarters and Base Camp, which were set up on the border between the Kingdom of Fire and the Kingdom of Kawasaki, and it was only [-] kilometers away from the front line of the battle. It is entirely possible for Sand Ninja's small force to bypass Konoha's line of defense and infiltrate and destroy the Land of Fire.

Logically, they should go to the headquarters as soon as possible, but because of the physical problems of some ninjas, they have to rest here tonight.

That's why Anbu Ninja came to remind Kushina to be vigilant.

As they got closer and closer to the battle zone, most of the team began to get nervous, but this majority did not include Yuromo.

Even he himself didn't know why he showed extraordinary adaptability to war.

At this time, although he was also listening to Anbu Ninja's reminder beside Kushina, he had an expression of indifference on his face.

The tent that Kushina was in was her special treatment. As a disciple, Yuromo could also shine, so that he wouldn't be crowded with those Anbu ninjas at night.

After Anbu Ninja left the tent, he took out a small scroll and began to write and draw on it.

Kushina glanced curiously, and then asked:

"Is this an improvement of the Lisixiang seal?"

Yes, Yuyi is a person whose mind can't be idle, and at this time he is trying to improve the four-element seal technique again.

"Yes," Yuyi nodded, and then continued: "The Lisixiang sealing technique is undoubtedly the most powerful sealing technique, but the problem is that it is too powerful and consumes too much chakra. This is still second. The biggest flaw is that the scope of action is too wide, and it is easy to kill the caster together, so I hope to change its scope of action to be smaller."

How long has it been since Yuyi started to learn the sealing technique, and at this time he actually started to try to change the S-level forbidden technique!

Kushina's first reaction was to prohibit it. After all, developing and improving ninjutsu is an extremely dangerous job, not to mention the most complicated sealing technique among various techniques. If a mistake is made, it is likely that not only Yuyi I, together with these dozens of people, have to finish playing together.

But after she saw the detailed arguments on the scroll and the improvement method of the technique, she hesitated for a while. As the Uzumaki clan, Kushina is an expert in the sealing technique, and Yuyi has already carried out part of the work. No mistakes or omissions were found, which meant that he was on the right and successful path, which made her unable to make up her mind for a while.

Looking at Kushina's hesitant face, Yuyi knew what she was thinking of, so he said quickly: "Don't worry, Teacher Kushina, I'm just demonstrating, I won't conduct random experiments, I'm not that afraid die."

Hearing what Yuyi said, Kushina was relieved a lot, but she still said very seriously: "I agree with your research work, but you must obtain my consent before any experiment to improve the technique. At that time, I must Be there, otherwise you can't do any experiments, understand?"

"Understand, absolutely understand."

Yui hurriedly said that he knew what to do. After all, in the ninja world, there is such a saying called cherishing life and staying away from lunatics who like to develop forbidden arts...

As the night deepened, the bonfire in the camp was extinguished, the medical ninjas had already rested, and only one team of Anbu left to keep watch.

However, although there was no bright light source, Yuyi walked out of the tent, and he was still performing the deduction of the sealing technique under the moonlight.

The moonlight is very bright today.

As time passed, Kushina had fallen asleep.

But all of a sudden, the pen in Yu Yi's hand stopped, and his brows furrowed unconsciously... It wasn't because of any difficulty in his deduction, but because he found that someone was quietly approaching the camp.

enemy!

Unexpectedly, the enemy appeared just after nightfall.

Because it was still within the territory of the Fire Country, the camp of Yuyi and the others was not too deliberately concealed. If the enemy could find this camp, it would not be a surprise.

Hagoromo stood up, and put the pen and scroll back into the ninja bag.

The Anbu ninja who was on duty noticed the movement of Yuromo.

He didn't speak, but made a gesture signal to Yuyi.

"What's wrong? Did something happen?"

Yuyi stretched out a hand from the cloak, and then quickly changed gestures: "At six o'clock, in the woods 400 meters away, we found four enemy targets."
