Reborn into Naruto World with Tenseigan-Chapter 796 - Testing the Limits of Yin Seal

Following Kuroto’s instructions, Yagura and Pakura dispatched hundreds of Kirigakure and Sunagakure Shinobi to investigate Aoki’s whereabouts under the pretence of searching for Danzo’s whereabouts.

Kuroto believes that sooner or later he will receive some information in regard to Aoki, saving him a lot of trouble.

With that out of the way, Kuroto decided to put his attention on the Yin-seal.

The improvements and verification steps were almost completed a few days ago, now only the final implementation step is left. Kuroto has to be very cautious with this since he is going to be using his body for this.

Since there is also the presence of the ‘Caged Bird’ seal on his forehead, that has to be taken into account as well while implementing the seal.

From a technical point of view, the improvements he made in the Yin-seal are a major breakthrough in Fuinjutsu. And in this whole process, Kuroto’s Fuinjutsu knowledge has also reached another realm. It won’t be wrong to say that in today’s Shinobi World, there are only a handful of people who are as good as him or perhaps better than him when it comes to Fuinjutsu.

Be that as it may, Tsunade-hime has forbidden Kuroto from sharing this knowledge, therefore, no one will know about Kuroto’s achievement, and they won’t be able to use Yin-seal either. Well, it doesn’t really matter to him either way, his objective was to use the Yin-seal and that’s nearly completed, so he is content.

After taking care of some final arrangements, Kuroto started the sealing process.

Since he has been through these steps several times already with those clones, the sealing process went smoothly. It took him only three hours to complete the sealing technique and all the chakra meridians in his body were connected with the Chakra storage space in the forehead.

With the sealing process completed, he focused on the testing step.

Because he was very careful and delicate during the entire sealing process, there was no conflict between the Yin-seal and the ‘Caged Bird’ Cursed Seal. In fact, the presence of the ‘Caged Bird Cursed Seal’ made the Yin-seal stronger and more protected than he had imagined.

He breathed a sigh of relief only after he had tested out the seal and started to note the observations, “Well, I suppose it’s time to note my observations.”

Yin-seal is undoubtedly an incredible Fuinjutsu, however, it cannot store chakra indefinitely. Like every other Jutsu, it has its limitations and that is the extent of Chakra a Shinobi can store in the Yin-seal. Once the sealing space in the brain is filled, no matter how much Chakra is extracted from the body and directed towards the sealing space, it will be useless.

And Kuroto wants to figure out this limitation.

With this purpose in his mind, Kuroto moulded Chakra in his body using the spiritual energy and physical energy of his mind and body. The moulded chakra was transferred to the Yin-seal space via the chakra meridians in the body. This process continued for a while until Kuroto started to feel weary. Feeling exhaustion taking over, he couldn’t help but mutter, “it’s quite exhausting.”

After taking some deep breaths, Kuroto recovered a little and checked the state of the seal. He was surprised to find that only 10 per cent of Chakra was lost in the entire process from moulding Chakra to transferring it into the Yin-seal sealing space.

“It seems there is ninety per cent efficiency,” muttered Kuroto and noted this observation in his logbook.

Currently, the Yin-seal space is empty so the loss is obviously very low, as more and more Chakra will be sealed in the sealing space, the efficiency will be reduced and loss will gradually increase, this is unavoidable and Kuroto has taken this factor into account.

In fact, 90 per cent efficiency is already very good, Kuroto didn’t expect such high efficiency.

After estimating the efficiency and loss ratio, he once again sensed the sealing space, this time he wanted to determine the size of his Yin-seal sealing space.

Based on Kuroto’s observations, the sealing space is nearly empty despite the Chakra he stored inside it not long ago, this means the size of the sealing space is quite large. As far as Kuroto can guess, the chakra he transferred a while back has filled less than 0.1 per cent capacity of the sealing space.

That means if he wants to fill the entire sealing space, it will require him to transfer more than two to three hundred per cent Chakra than he did a while back. Transferring so much chakra into the sealing space will take at least a few years, and that too when he continuously transfers Chakra into the sealing space.

This calculation is based on the increase in loss as the capacity of the sealing space will be filled. After all, over time, the efficiency will decrease, therefore, it will take more time to fill the entire sealing space.

As Kuroto was writing everything in his logbook, he suddenly realized that the Yin-seal and Hachimon Tankou are quite compatible with each other. Using Yin-seal, Kuroto can put himself in a state of extreme fatigue, and in that state, if he carries out Hachimon Tankou training, he will be able to push himself faster and break his limits in less time.

So using Yin-seal will not only allow him to constantly store Chakra in the Yin-seal sealing space, but it will also increase the efficiency of Hachimon Tonkou.

As for the worry of injuring himself due to wear and tear, for ordinary people, this may be a big problem that is very difficult to avoid, for Kuroto, this is not a big deal. Because of his current strength and recovery speed, as long as Kuroto doesn’t push himself too hard he will continue to recover and not suffer from irreversible damage.

“Well… I guess this helps a lot.” He muttered as he put down the notebook and left his house. He was going to his private training field, he wanted to test how the chakra stored in the sealing space of Yin-seal will be released.

For the next few days, Kuroto continued to test the limits of Yin-seal. The results he got from his tests satisfied him greatly. Kuroto is quite sure that the performance of the Yin-seal that he has designed for males won’t be worse compared to the Yin-seal that Tsunade-him gave him.
