Shinji reacted quickly, and said to Yakumo and Yin Du at the same time with 'Naobi', "Don't panic, you just successfully launched that children's art!" ”

"Success?" Yakumo and Yin Du were all shocked. After a little combing, Shinji grasped the situation in front of him and explained: "That mysterious children's technique hidden in the eyes of the red dragon should be a kind of time and space ninjutsu!" ”

"When... Time-space ninjutsu?! "Yakumo and Yin Du are both a little confused. Apparently. A technique of this level like 'Time and Space Ninjutsu' is a bit too complicated and high-end for the two of them who are still ninja students.

"That's right, it's time and space ninjutsu!" After a pause, Shinji said, "I preliminarily deduce that the ability of this technique is to replace the positions of the two of you. Yin Du immediately said: "No wonder I suddenly returned to the village." Only then did Yakumo realize that the position she was in now was the same place where Yin Du was a few seconds ago, because she had changed her position by activating the Tongjutsu, so she had come here from the village all at once.

After a brief explanation, Shinji did not rush to speak, but secretly analyzed while observing.

Red Dragon's Eye's children's technique reminded him of another time-space ninjutsu, that is, the time-space ninjutsu 'Wheel Tomb Side Prison' hidden in Madara Uchiha's reincarnation eyes.

Because after activating the 'Wheel Tomb Side Prison', the deity can also be replaced with a special clone in space to achieve the effect of shuttling through space.

However, after thinking about it carefully, he found that the difference between the mysterious children's technique of the red dragon eye and the 'Wheel Tomb Side Prison' was still very obvious.

The Tomb Wheel Clone of the 'Wheel Tomb Side Prison' cannot stay away from the deity, and has to return to the deity every once in a while, and then re-emerge.

Therefore, the temporal and spatial effect of the 'Wheel Tomb Side Prison' is more reflected in the temporary replacement of positions between the deity and the clone to avoid attacks.

And this children's technique of the red dragon eye seems to have no limit in terms of distance, and there is no problem with the space replacement at a distance of at least one hundred and thirteen kilometers, so it is more like another time-space ninjutsu.

"Yin Du is like the fourth generation's special kunai engraved with the 'Flying Thunder God Technique', where she is, Yakumo can teleport through her!" Shinji found that compared to the 'Wheel Tomb Side Prison', this children's technique of Red Dragon's Eye is more like the 'Flying Thunder God's Technique', which has become famous for four generations.

And Yin Du is like the special kunai that is transmitted by the fourth generation positioning!

"If that's the case, then this children's technique of the red dragon eye is a youth version of the 'Flying Thunder God Technique'..."The fourth generation of the 'Flying Thunder God Technique' is strong in the ghostly nature!

There are as many special kunai as carved with the Flying Thunder God Technique, and the four generations have as many teleportation markers as they can choose from, and the four generations themselves can also use the Flying Thunder God Technique on objects, even on the enemy's body, to locate the coordinates.

In comparison, the Red Dragon's Eye's children's technique is inferior to the 'Flying Thunder God's Technique' in terms of the number of teleportation marks and the way it is cast.

Soon, Shinji thought of another drawback of this technique. That is, Yakumo and Yin Du must be launched at the same time in order to successfully activate the time and space ninjutsu of the red dragon eye.

"No wonder no matter how much I researched at the time, I couldn't start this children's art..."Shinji suddenly realized.

From the current point of view, if you want to launch this technique, you need to separate at least a blood clone containing the power of the red dragon's eye.

It's not that hard. The real difficulty lies in how to communicate with one's own blood clone, how to agree to launch the Tongshu at the same time when they are far away, lose each other's vision, and have no communication.

You know, the situation on the battlefield is often fast-moving, and you can't agree on it in advance or try it slowly.

A single mistake, or even a slight hesitation, can make the difference between victory and defeat.

"Hey!" After thinking about this, Shinji sighed quietly. The joy of discovering that the children's art contained in the eyes of the red dragon was the time and space ninjutsu was also washed away by this analysis.

Yakumo and Yin Du were immersed in the excitement of mastering a time-space ninjutsu. In just a short period of time, they have already swapped places four or five times.

After hearing Shinji's sigh, Yin Du, who had just been replaced, hurriedly asked, "My lord, what's wrong?" Why are you sighing? Shinji shook his head and didn't say anything.

After all, this is a time and space ninjutsu, no matter how many restrictions it has, as long as it is used well, it can still play a miraculous effect.

Swish... At this time, Yakumo changed back and asked Shinji, "My lord, after mastering this children's art, can I leave the village at any time?" Shinji smiled, and was just about to answer, when he suddenly thought of something, and was stunned for a moment.

The analysis he had just made was based on his own use of the red dragon's eye, but if the red dragon's eye was used by Yakumo, the situation would be completely different.

Shinji can't communicate with his blood clone remotely, but Yakumo, who has Yin Du, can. Therefore, the problem of communication is an insurmountable trouble for ordinary red longan users, but it is not a problem for Yakumo at all.

Thinking of this, Shinji had a new guess, and hurriedly said to Yakumo in front of him: "Yakumo, you go back first, I'm going to do another test!" ”

"Oh!" Yakumo responded, launched the Tongshu again, and exchanged positions with Yin Du. Shinji didn't delay, and said directly to Yin Du, who was replaced: "Follow me!" Although his mind was full of doubts, Yin Du still pressed down and followed Shinji closely.

The two of them sped at full speed, and soon returned to the place where they had met tonight, which was the grove about forty-five kilometers away from Konoha.

After reconfirming the distance, Shinji immediately instructed Yin Du, "You now remove the blood clone and return to the spirit state!" Yin Du hurriedly complied, lifted the blood clone, returned to the original spirit state, and reported to Shinji: "My lord, that sense of restraint has reappeared. Shinji waved his hand absently, what he was testing now was not the activity distance of Yin Du's spirit state, but he wanted to test whether Yin Du could cooperate with Yakumo to launch children's magic in the spirit state.

If Yin Du can also cooperate with Yakumo to launch that child's technique in the spirit state, then Yakumo is equivalent to having a 'Flying Thunder God Kunai' who has the flight speed of a spirit body, ignores physical attacks and general ninjutsu, and can communicate at any time.

If that's the case, then the value of this children's art is too great. Except for the special means of enchantment and sealing, ninjas have almost nothing to do with the spirit body, once Shinji's guess comes true, then Yakumo has the ability to sneak attack comparable to the 'Flying Thunder God Technique', because Yin Du in the spirit state can't guard against it at all...
