With the order of the Hyuga Mirror, hundreds of Fog Hidden Elite Shadows began to investigate the whereabouts of Hinata Aoki in the ninja world under the guise of searching for the group.

For the ability of the fog to collect intelligence, the Hyuga mirror is still very confident.

In the search for Deidara, as well as the hunting and killing of the group and other key events, almost all of the information provided by the fog concealment played a decisive role, saving Hinata a lot of trouble.

It can be said that the original choice to consume a 'other gods' and secretly control the four generations of Mizukage Goji Tachibana Yakura is indeed a very far-sighted move in the current view.

After arranging these, Hyuga Mirror did not waste time in vain and sat at home waiting for information on the fog concealment, but reined in his mind and began his cultivation of the 'Yin Seal'.

Strengthening himself in his eyes always has a higher priority than weakening the enemy.

Back at home, Hinata Mirror began the final work on the improved draft, and after the loss of the previous eight clones, the verification of the improvement of the 'Yin Seal' was actually completed.

From a technical point of view, this improvement has made a major breakthrough in the sealing technique of the Hyuga Mirror, and it can be said that with the completion of the improvement of the 'Yin Seal' this time, his attainments in sealing have also reached a new level.

It can be said that in today's ninja world, there are only a handful of people who can suppress the Hyuga Mirror in terms of sealing skills.

However, because he had promised Tsunade Ji before, the improved 'Yin Seal' this time, the Hyuga Mirror will only be used for his own use, and will not be passed on to others.

After completing the final arrangement of the improved draft, Hyuga Mirror did not delay and immediately began the cultivation of the 'Yin Seal'.

Because he had already studied it very thoroughly, and had also used clones to cultivate many times, his cultivation of controlling the Yin Escape Buddha-figure was very smooth this time, and it only took him about three hours to complete the burning of the sealing technique at the center of the eyebrows, as well as connecting the sealing area at the center of the eyebrows with the meridians of the body.

Subsequently, Hinata carefully tried.

Fortunately, he found that there was no conflict between the 'Yin Seal' and the 'Caged Bird', and even because of the 'Caged Bird', the brain area of the Yin Escape Buddha was protected by the 'Caged Bird', making the 'Yin Seal' located in the storage chakra sealing area of the brain, which was even stronger than he had expected!

After completing the initial cultivation of the 'Yin Seal', Hinata Mirror exhaled lightly, then took out the notebook he had with him, and wrote and drew on a blank page, and the title at the top was 'The Test of the Yin Seal Chakra Storage Limit'.

There is no doubt that the 'Yin Seal' is indeed a very clever sealing technique.

But it can't store chakras indefinitely, and like all seals, there is a limit, and its limit is the sealing area located in the brain region.

Once the entire sealing area is filled, no matter how much the chakra in the meridians is extracted, it will no longer be able to store a single trace.

Therefore, testing the storage limit of the 'Yin Seal' is the first scientific research project to be completed after Hinata Master the 'Yin Seal', and only in this way can he know himself and his opponent.

And the method of testing is actually very simple, the Hyuga mirror took out the 'earth escape clone' brought out of the air fortress this time from the sealing scroll, placed it opposite the Yin escape deity, and then manipulated the Yin escape deity to launch the 'Yin Seal', extracted the chakra of the Yin escape deity's whole body, and continuously transported these chakras to the sealing area of the 'Yin Seal' through the meridians in the body.

"I'm so tired!"

After a long time, the Hyuga Mirror, who had completed the Chakra Seal, shook her head and felt a wave of tiredness from the depths of her soul.

Refining chakra consumes not only the energy of the body, but also the spiritual power, so after extracting the chakra of the whole body at one time, not only the body is exhausted, but even the spirit body will have various adverse reactions such as trance and loss of consciousness.

What's more, the Hyuga Mirror has not consumed chakra to this point for a long time.

After slowing down for a while, the Hyuga Mirror carefully sensed the sealing area located in the brain, and found that about ten percent of the chakra was lost during the entire sealing process.

In other words, if the amount of chakra refined by the helioscope is 100 standard units, then only about 90 of them can really be stored, and the rest are lost in the process of refining, moving, and storing.

"Ninety percent storage efficiency..."

Hinata muttered as she made notes in her notebook.

This level of attrition is still acceptable to him, but at the moment the sealing area is empty, so the loss will be smaller, and as the number of chakras in the sealing area will increase in the future, the loss will inevitably increase gradually, which is unavoidable.

After estimating the loss ratio, the Hyuga Mirror calmed down and sensed the sealing area again, and then the corners of his mouth rose slightly.

After completing this chakra storage, the sealing area is still empty, and it can be seen that the capacity of the sealing area is very considerable, and according to the estimation of the helioscope mirror, the amount of chakra he has this day only occupies about 0.1% of the capacity of the sealing area.

If calculated according to this data, the Hyuga mirror needs to fill the entire sealing area, and it will take three years to continuously send chakras to the sealing area.

Of course, this calculation is inaccurate, because as the seal area is filled, the loss will gradually increase, and the storage efficiency will gradually decrease, so it may take more than four years to completely fill the seal area.

In order to further verify this, the Hyuga Mirror launched the 'Baihao Technique', and then instantly threw the spirit into the opposite Tu Dun clone, and observed the whole process with his white eyes in the state of activating the 'Baihao Technique', as well as the sealing area in the Yin Dun Buddha's brain, and through the perspective of the Tu Dun clone, he reconfirmed the amount of chakra for a day, which only accounted for about 0.1% of the total capacity of the sealing area.

After the spirit returned to the Yin Escape Figure, the Hyuga Mirror began to record data in her notebook.

As he wrote, he suddenly realized that the 'Yin Seal' and the 'Eight Gate Dunjia' were actually very compatible, because through the 'Yin Seal', he could quickly make his body enter a state of extreme exhaustion, which could save a lot of time consumed by exercise.

Because in the extreme state of the body, the efficiency of cultivating the 'Eight Gate Dunjia' is the highest.

As for the wear and tear on the body, for ordinary people, this may be a big problem that is difficult to avoid, but for Hinuga Mirror, this is not a big deal, because with the current strength of his Yin Escape deity, as long as he does not go too far, it will not cause irreversible damage to the body...
