It worked, although it has not yet undergone specific experiments, but on the surface it is indeed a success!

Uchiha Kai feels that today's mood is really like a roller coaster.

He didn't feel like going to the toilet, but he had a feeling of lack of oxygen.

He seemed to understand a little bit about why a certain guy named Fan Jin that he had studied in the past was crazy.

This feeling was so exciting that people couldn't say it, and he only felt that his heart was beating a little too hard.

Taking a deep breath and looking at the utensils in front of him, Uchiha Kei pondered for a moment before asking, "Can this thing be tested for skin?" ”

"Test for allergic reactions and negative effects?" Hinata Aya thought for a moment: "I don't know, there is only such a thing as blood type matching, and there doesn't seem to be such a test as a skin test, but you can try it." ”

"Then let's do a skin test." Uchiha Kei said directly: "As long as it doesn't have a big impact on me." ”

Hinata Aya nodded, and then began to prepare for the skin test experiment.

Although she didn't know whether the skin test had any effect.

After all, this thing is a bit beyond her knowledge, but it won't be a problem to try.

After extracting some serum, after sterilization, she took a syringe and pulled out the sterilized blood, and then slowly walked to the side of Uchiha Kai.

"I hope it works, otherwise I don't know what to do with it."

Hinata Aya said while helping Uchiha Kai do a skin test, "Also, remember to have someone clean up the flies here." It seems like a little too much today. ”

"Too much?" Uchiha paused for a moment, and then his face became a little strange: "What did you do with Uchiha Yong's corpse." ”

"It's not me who handles it, it's those people who handle it." Hinata Aya glanced at Uchiha Kei: "But as far as I know, it was burned and cleaned." ”

"Is that so, are you sure you found it today?" Uchiha Kei lowered his head, looked at the syringe that Hinata Aya pulled out, and asked calmly after looking at his arm.

"Yes, it's today." Hinata Aya nodded, and the next moment she opened her eyes: "About a kilometer to the east, there is only one person, if there is no accident, it is from the Youru clan." ”

Uchiha Kei nodded, then stood up and walked outside: "How long?" ”

"Twenty minutes."

"Make preliminary preparations first, disinfect everything, whether you use it or not. I'll be back in twenty minutes. ”

.....

One of Danzo's most loyal subordinates, he joined the root early on, and he wasn't the one to be forced to join.

He felt that the roots were a perfect fit for him, and some of the ideas of the roots were also very suitable for him.

His respect for Tuan Zang has reached the point of fanaticism.

Years ago, because he had a mission in hand, he didn't follow Tuan Zang to the Land of Rain to carry out a mission.

Even if that time it turned out that only Tuan Zang came back, he really wanted to participate, and in his opinion, Tuan Zang was the one who supported his beliefs!

This time Danzou gave him a mission to spy on a small imp of the Uchiha clan named Kei Uchiha.

Yau Ru Ryoma knew about this imp, and before he could gather his information, he knew that this imp was the head of the Ministry of Guards.

I'm afraid that not many people in the village don't know about this matter.

However, Yau Ru Ryoma didn't care about the identity of this little ghost, and after some understanding, he basically determined that this little ghost was the puppet of Uchiha Fugaku.

Such thoughts are common in the village, and although everyone doesn't say it, who can believe that a little ghost can really control the security department?

Although he didn't care too much about Kei Uchiha, Yaru Ryoma still carried out the mission seriously.

As a ninja, it's their duty to take every mission seriously.

As a root, the mission given by the group is the mission they must accomplish.

The Youru are very good at using bugs, which are their best weapons of battle and the perfect tool for infiltration.

Yau Ru Ryoma is an elite member of the "root", and his invasion technology is also very prominent among the shadows of the past dynasties, so you can imagine how terrifying his ability to gather intelligence is.

After a few days of observation, he noticed that something seemed to be wrong.

Because the entire guard department seems to be completely a word of Uchiha Kai!

This made him realize that I am afraid that everyone has some misunderstanding about the two of Uchiha Kai and Uchiha Fugaku, maybe Uchiha Kai is really capable and powerful?

And he noticed that Uchiha Kei would often leave the guard department and disappear, which made him think there might be something wrong with this.

He decided to follow Kei Uchiha, only to find that there were a lot of arrangements and even some seals to keep others from entering.

This discovery made Youru Longma realize that there was really some secret hidden here, otherwise it wouldn't have been like this!

Yau Ru Ryoma decides to go inside, to investigate what is hidden inside.

He didn't choose to go back and report directly, he wanted to get more information and let Tuan Zang know everything here.

He was very careful, and after a few days of research and investigation, he had figured out the number of patrols and some of the defenses here.

However, the layout here is very terrifying, no matter how good he is, he can only get close to the destination for about a kilometer.

In depth, I'm afraid he will be discovered.

The least noticeable bugs are the ones that are barely visible and not easy to spot.

Yaru Ryoma thought the same thing, but he couldn't figure out where the Uchiha had gone.

So he decided to use the tiny bugs as well as the most common bugs, such as flies.

Some people may check for the tiny but uncommon things, but the most common ones are often not taken seriously.

Waiting quietly, when the first bug came back to report, Youru Longma found that he didn't seem to be too outrageous.

Uchiha Kai really has a secret, there is a huge underground laboratory in that place.

And that place does have the function of preventing insects.

It's just that the flies and other things exist in that place, so everything is fine.

Ryoma was constantly gathering information, and he knew that Uchiha Kei seemed to be doing some experiments, and he also found out that Uchiha Shu was also in it through bugs.

"But it looks like something has gone wrong, I'm afraid Uchiha Isamu was also responsible for it."

Yau Ryoma wrote down what he had learned on a piece of paper: "As for the Uchiha Kai's experiment, it's a pity that he crumpled that report, and the flies couldn't open it at all.

But that's enough, he should really do some cell experiments or something. ”

After he had written everything down, he took a stamp, and the handwriting on the paper disappeared without a trace.

But just as he was about to summon the psychic beast to deliver this note to the root, he, who has been a combatant all year round, suddenly felt a strange crisis!

Almost instantly, the oil Ruryoma completed a seal.

When he appeared on the branch next to him, he could clearly see that the worm clone had been cut in half by a knife that had been cut in half, and that knife had burned the worms even more.

Obviously, this knife is not ordinary, even from a long distance, he can feel the thunder attribute chakra on the knife.

"Uchiha Kai?" You Ru Longma can basically tell who the person is.

This kind of sword technique Konoha is actually used by only two people, one is Kakashi, who has entered the shadows, and the other is the head of the Konoha Security Department, Uchiha Kei.

Obviously, the only person who appeared in this place was the head of the Konoha Security Department, Uchiha!

Raising his head slightly, and sure enough, Yau Ru Ryoma saw a teenager in a black combat uniform standing there.

The shinobi knife in his hand still had blue chakra blooming.

"The Shadows? And the oil of the Ru clan? Uchiha Kei looked at this oil Ru Ryoma calmly: "Who asked you to come?" ”

“....”

Yau Ryoma didn't speak, he looked at Uchiha Kei in silence, but he was thinking about how to get out of here.

And, how to defeat Kei Uchiha and get him out of here with him!

For the Shadow Ninja, exposure is equivalent to the failure of the mission, and if valuable information is later present, it is still acceptable.

But for the root ninja, defeat is equal to death, and the only remedy is to come up with more valuable information!

Uchiha Kei is obviously studying something, and this matter is also about Uchiha Shu.

Obviously, this guy framed Orochimaru in the first place, which is a good piece of information.

If you can subdue Uchiha Kai and bring it back for investigation, then many things can be tried to undo.

For their root ninjas, they don't care about any position like the head of the security department.

Especially when they have already determined that the target has something to hide, and something dangerous may be created.

Taking a deep breath, a large number of bugs began to emerge from the oil Ru Ryoma's body, and he had already shown his attitude!

"Looks like I'm doing the right thing."

Uchiha Kai nodded: "Obviously, you all treat me as a puppet, but that's fine, although there will always be some minor troubles, but it won't be a big problem." ”

As he spoke, Uchiha Kai's scarlet chakra eyes began to slowly change, and in the blink of an eye, a pair of strange triangular diamonds appeared in his eye sockets.

At the same time, pitch-black chakras appeared on his body.

The chakras were suffocatingly cold, and as the chakras spread, a giant with dark eyes and scarlet eyes appeared on him.

The giant was covered in bones, but with the eruption of the Uchiha Kaichakra, the base of the skeleton was slowly covered with meridians and flesh, and soon it was wrapped in a coat-like chakra.

The most important thing is that a pitch-black ninja knife appeared in the hand of this giant!

"It just so happens that I haven't tried this strength yet, congratulations, you've become the first."
