From the seal, Kuroto has learned that there are two different approaches to using the Transcription Seal, and each approach has a certain difference in the result.

The first approach is the same as when Itachi sealed Amaterasu in Sasuke's Sharingan or when he programmed Shisui's Mangekyou to activate Kotoamatsukami when it encounters Itachi's Mangekyou Sharingan, in this method the seal would only work once, and then the programming will disappear. ​​

The other approach is to transfer a part of your visual prowess, but here's the catch, when you transfer a part of your visual prowess, then part of your visual prowess will be separated from you and will be sealed at the target, and when that part of visual prowess is separated from you, your visual prowess will decrease by that exact same amount, although it can be recovered at a later date; until it's recovered the user's visual prowess will remain decreased. One of the advantages of this approach is that it works the same but there wouldn't be just one use, so long as the chakra supply is there the programming will keep working.

But there is another limitation with the second approach, for this approach to work the user has to be alive, if the user dies then the programming will also disappear, which is not a limitation for the first approach in which the Transcription Seal will work exactly as it was programmed even if the programmer dies.

Both approaches have their advantages and limitations and it depends upon the user's needs which one suits his needs.

For Kuroto, the second approach is more suitable as such he is going to try the second approach.

(p.s. for convenience's sake we are going to call them Transcription Seal-1 and Transcription Seal-2 respectively.)

To do so, Kuroto took out the Suijin clone from the Nutrition Tank and placed it on the Test Bench.

After making sure that the clone was in perfect condition, Kuroto was ready to use the Transcription Seal-2.

Closing his eyes, Kuroto urged the visual prowess of his Tenseigan and then suddenly opened his eyes, the next thing he did was to gently touch the forehead of Suijin Clone with his index finger.

Instantly the seal was activated and Kuroto was able to feel a part of his Tenseigan Visual prowess separating from him and being sealed in the semi-finished Byakugan of the Suijin Clone.

After the seal was completed, Kuroto could feel that his insight has dropped a little compared to before.

And that was not all, since he did not use Ryuumyaku Chakra while using the seal, Kuroto also felt that a fourth of his chakra was also emptied instantly, which led to a momentary sluggishness and Kuroto had to take the support of the test bench to stabilize his figure in order to not fall because his legs were a bit softened.

'It turns out that the burden of using 'Transcription Seal' is so heavy! No wonder only a few individuals of the Uchiha Clan are known to have used this technique, and it instantly resulted in Itachi's death as soon as he sealed Amaterasu in Sasuke's Sharingan!'

Even without the use of Ryuumyaku, Kuroto can certainly say that his chakra reserves have grown very high over the years, although not to the exaggerated level of Senju Hashirama, or Uchiha Madara, it wouldn't be wrong to say that his chakra has far surpassed the chakra reserves of the legendary Sannin, which in itself says that his Chakra reserves are also huge.

And even then, a quarter of his chakra was consumed in using this just goes to show just how taxing Transcription Seal is!

Kuroto soon stabilized his situation and after putting away his thoughts he walked towards the Test bench to see what changes have occurred in it.

After a while of observation, Kuroto frowned, as he found that there seems to be no significant change in the Suijin Clone on the first observation.

"Did it not work?"

Kuroto was a bit confused, to confirm his doubt, he activated the Tenseigan and again carefully observed the Suijin Clone.

"Ah, that's a bit… interesting I guess?" – Kuroto muttered with an intriguing look.

This is because, in his Tenseigan vision, Kuroto was able to notice an imperceptible Chakra reaction inside the right eye of the Suijin Clone lying on the Test Bench, but this chakra reaction was too subtle and if it wasn't for his Tenseigan, Kuroto is sure that he would have been unable to notice it.

And this is the exact reason why Kuroto found this turn of events to be a bit interesting.

Almost a quarter of Kuroto's chakra was transferred while using the Transcription Seal and yet he only perceives a very imperceptible chakra reaction from the Suijin Clone.

Does that mean that most of the chakra was lost?

Not really, the chakra is not lost and it has perfectly taken root inside that Byakugan as per Kuroto's programming.

Then why the subtle chakra reaction?

It just means that perceiving the chakra sealed using the Transcription Seal is very difficult and needs extreme insight.

Since the seal was successful, Kuroto needs to see what is the exact difference between the previous and current state, after all, a part of Rein Wheel Interaction power which is one of the many techniques that the Tenseigan has to offer has been sealed inside the Suijin Clone so Kuroto has to also understand these changes that this transfer of some of his visual prowess leads to!

So, to be able to do so, Kuroto turned around and reached out his hand towards a large cabinet in the corner of the lab.

"Rein Wheel Pull!"

Huala…

Instantly the cabinet was pulled towards Kuroto under the effects of an attractive force.

After confirming what he wanted, Kuroto used "Rein Wheel Push!" to push back the cabinet to its initial position and thought to himself, 'Sure enough, there is some decrease in the amount of force that I am able to exert using Rein Wheel Interaction with the same amount of chakra consumption.'

After confirming this, Kuroto understood that the Transcription Seal - 2 can not be abused.

Because each time the seal is used, the caster's visual prowess will decrease which is a risky thing, therefore it is better to only use the Transcription Seal - 2 when extremely necessary.

With that confirmation and understanding, Kuroto sat on the chair and used the 'Tenseigan Soul Descend' to transfer his soul into the Suijin Clone body.

As Kuroto closed his eyes, Suijin Clone's eyes opened, and he sat up.

Suijin clone has already been used by Kuroto several times, as such, this time Kuroto did not feel even a bit of sluggishness and he was in perfect sync with the clone body.

After spending a while getting used to the different body, Suijin jumped off the test bench swiftly and tried to use the Rein Wheel Interaction which has been sealed inside this body by Kuroto using the Transcription Seal-2.

'Hmm, I feel it, the Transcription Seal-2 has indeed worked and something is sealed in the right Byakugan of this body!'

To see the effects that this sealed ability will have, Suijin stretched out his hand towards the same cabinet and urged his chakra.

"Rein Wheel Pull!"

Huala…

Just as intended, the cabinet was pulled towards Suijin under the traction force of Rein Wheel Pull.

Then he used Rein Wheel Push to push back the cabinet into its previous position.

After confirming that Transcription Seal-2 was indeed working, Suijin thought, 'Although the effect of the Rein Wheel Interaction is 20% weakened, there is no doubt that Transcription Seal is working perfectly as intended.'

With this guess confirmed he did not stay in the Suijin body any longer and used Tenseigan Soul Descend to transfer his soul back to the main body, and also withdrew back the chakra he sealed inside Suijin's Byakugan.

Although this method seems to be very useful; Kuroto does not intend to divide his strength.

"Despite all of its shortcoming, the Transcription Seal is really amazing, whether type-1 or type-2, both of them have their uses and will be very useful!"

Prior to this, Kuroto was always doubtful that how come Uchiha Madara managed to fool Shodaime-sama and Nidaime-sama, after all, if there is Izanagi pre-programmed in his Sharingan, there should have been some Chakra reaction.

And it must be known that the perception abilities of Shodaime-sama and Nidaime-sama are obviously extremely good, as long as there is even a bit of chakra reaction in Madara's body both of them would have easily discovered that something is wrong.

But they did not, and Uchiha Madara fooled them with Izanagi.

They were unable to notice because the chakra reaction of the Transcription Seal is extremely subtle.

Even Obito suffered from Itachi's Amaterasu because of this, otherwise, how come Obito did not notice that there was Itachi's Chakra present in Sasuke's Sharingan?

It is obviously because the chakra reaction of the Transcription Seal is imperceptible.

Understanding this, Kuroto can't help but think that how so many amazing techniques have been held in the Uchiha Clan, Izanami, Izanagi, and the Transcription Seal are some of the few techniques that Kuroto knows… this does imply that these are the only techniques.

The destruction of such a clan is a huge loss for the world of shinobi!

From Kuroto's perspective whether as a shinobi or as a scientific researcher, the Uchiha Clan is just too valuable to be allowed to be destroyed, therefore, even if not for the promise he made to Shisui, Kuroto would not allow the Uchiha Clan to disappear.

All that aside, now Kuroto has confirmed that he can use the Transcription Seal-2 so he can now begin the fusion process of the two Mangekyou Sharingan pairs into the Eternal Mangekyou Sharingan pair.

Of course, before the process begins, he first needs to seal Uchiha Hideki's Mangekyou Sharingan technique Daikokuten into Ryota's right eye with the Transcription Seal.
