Naruto: Reincarnation With All Existence System - Volume 1 Chapter 37 Test Second Part Part 2

Now that Ren was able to use the sound wave jutsu, he decided to begin to practice the sound hypnosis jutsu. Ren was able to practice this jutsu by making a blood clone and then he would try to put it in a genjutsu. Once Ren made a blood clone he attempted to make a sound using the same chakra type that he used for other genjutsu, which Ren thought was yin chakra. After Ren did this he noticed that he needed to make sure that the sound waves don’t influence him as well and he needed to aim it. When Ren aimed the sound waves towards the blood clone he noticed that he made the sound wave too powerful.

So Ren tried again, but this time around Ren used a lot less chakra. Once the sound wave hit the blood clone Ren noticed that he still used too much chakra because he was used to doing that for sound wave jutsu. Then Ren continued to practice this jutsu for the next twenty minutes and after now he could put the blood clone in a weak genjutsu. Normally Ren would move onto the new technique but he felt that he could still grow a lot with this jutsu by finding a method to use more chakra while not making the sound wave too powerful. After the first hour of doing this test, Ren now knew how much chakra he could input without making the sound wave too powerful.

Even though Ren was using the jutsu to the best he could right now it was a lot worse than the genjutsu abilities given to him from his dojutsu. Ren just thought that right now his chakra control wasn’t good enough to input more chakra without increasing power, so he just decided that right now he would move onto the inner vibration jutsu. Since Ren didn’t want to get damaged inside of his body from practicing this he decided to make it into steps just like what he did with the sound wave jutsu. The first step he made was inputting sound vibrations inside rocks without damaging them.

This step took Ren for almost 20 minutes, but now he could finally have sound vibrations safely stay in rocks. After this, the next step that Ren made was transferring the sound vibrations from one rock into another rock just from making contact. This step was a lot harder than Ren thought and it ended up taking him a whole 2 hours. Even though this was because the step was very difficult to do it also partly took him this long because he was running low on chakra so he needed to stop practicing jutsu and instead just get back his chakra.

Now that Ren completed the first two steps he decided that it was time to move on to practicing this inside of his own body. Ren started doing this by using very little amounts of sound vibrations in his body and then he touched a rock and tried transferring the sound vibrations. This process went fine for Ren, but he still wasn’t going to get over-confident and use too much sound vibration at once. Ren slowly increased the sound vibrations for ten minutes and now he knew what was around the peak amount of sound vibrations that he could have in his body without causing any harm.

The next thing Ren wanted to do was transferring sound vibrations almost instantaneously. When Ren first attempted to do this he only used very small amounts of sound vibrations because when the sound vibrations were moving at higher speeds they would cause move damage. After doing this for a little less than ten minutes Ren could now just quickly tap something and could transfer lots of sound vibrations to it at that moment. After Ren did this he wanted to attempt trying to combine the sound hypnosis jutsu and the inner vibration jutsu, this would work by having the vibration at the frequency for hypnosis and then input it inside someone’s body after he made contact.

Since Ren had already practiced that inner vibration jutsu for so long this was very easy to do, and it only ended up taking him 5 minutes. Since Ren had many hours left until he was going to be tested for his proficiency with the jutsu Ren decided to try and combine the sound wave jutsu with inner vibration jutsu. Ren would do this by making sound vibrations just outside of his body and then he would greatly amplify these vibrations to increase its power. Once Ren tried to do this he realized that the outside of his body was a lot stronger than the inside so he could use a lot more powerful sound vibrations.

Another thing that Ren realized that the sound vibrations couldn’t move that far away from his body and only go a maximum of three meters away from him, but the farther away it was the less powerful it was. Ren decided to name this jutsu outer vibration jutsu. The next thing Ren wanted to do was shorten the range of the jutsu, but keep its power so he could make it into almost like another set of armor over his skin. It took Ren 15 minutes to be able to do this, and the reason for this was because when Ren shortened the range he could also up the power of the outer sound vibrations. Ren decided to call this jutsu vibration armor jutsu.

The next thing that Ren wanted to do was combine the inner vibration jutsu with lightning chakra so that it could also influence someone’s nervous system. Since Ren didn’t have a very high affinity with lightning and experience with using lightning chakra it had been many hours and he still hadn’t succeeded in using lightning chakra with inner vibration jutsu. The main problem that Ren currently had was that whenever he stored the lightning chakra inside his body it would also influence his nervous system.

Also whenever he tried fusing it with lightning chakra right before making contact he didn’t have enough time and so the lightning chakra couldn’t fuse with the sound vibrations. Ren decided that currently, his inner body wasn’t strong enough yet to handle it so he decided to fuse the vibration armor with the lightning strike armor. Since Ren’s outer body was many times stronger than his inner body Ren very easily succeeded in doing this, but the main problem that this had was that it would use way too much chakra. Ren named this jutsu lightning vibration armor jutsu.
