Only one seal couldn't withstand the intense pressure, but that was okay, because these were just hastily made prototypes, and if they passed the stress tests, they would work with a guarantee when brought up to speed. In the meantime, the clone directed his hands with open palms forward and a real stream of visible chakra rushed forward from the tenketsu, almost immediately beginning to dissipate, but it did its job.
Boom!
Another version of the blocking failed, forcing me to cross out the item, and in the end, there were only two of the simplest and most reliable experimental seals, which I tentatively named "barrier" and "labyrinth" so as not to slip into trivial numbering, most accurately reflecting their principles of operation.
"Barrier" isolated the recognizing element in the seal, cutting off the access of any chakra to it, but it required constant feeding for its work and was barely noticeable even for the first degree of Uchiha dojutsu, which practically guaranteed the detection of even the worst biakugan, if you take the trouble to look closely, although it was characterized by a great simplicity in the creation and installation.
"Labyrinth" served as a kind of dam, building on the recognizing element, but not changing anything, but just gently accepting and imperceptibly diverting all the incoming impulse chakra to the side, not letting even a small stream through to the recognizing element and removing the very possibility of activating Hyuga Soke no Juinjutsu (Technique of the cursed seal of the main branch of the Hyuga clan).
The advantages of the variant were passive operation and general stealth, unlike the straight as a stick first variant. As long as there was no attempt to activate the cursed seal, even the Byakugan would not be able to detect anything - after all, the same chakra would be used to create it, it would go where it was needed, but without the desired result.
But, as with any passive variant, the complexity of using it on paper would be a bit higher than the kekkai variation, which would affect the speed of production and the experience requirements of the fuin user. There were also seishitsuhenka variants, but they didn't stand up to the test.
Of course, these are still draft seals that will be refined, improved, and simplified to the level of quality required of any Uzumaki who takes the path of seals, but even being able to choose between a couple of variations would be a great help to Hizashi when planning his little revolution, choosing between speed and stealth.
Especially since the vast majority of Hyuga, living in one large building, have been buying barrier fuin in packs from the shop, designed to provide long-term room privacy even from the Byakugan...
Byakugan in particular, since living in a clan of walking X-ray wielders leaves very little opportunity to maintain privacy even in one's own room. It's no wonder some Hyuga try to learn at least the Founders of Fuinjutsu, like Hizashi, to provide a bit of privacy.
This will also allow one to experience the seals and how they are noticed by the dojutsu before using them in public without fear of being seen, especially since how to pull off both versions I will also add in the creation instructions.
This should give a knowledgeable person a small opportunity to pick up the key to my other seals as well - each Fuin master's creation methods are different, but the general basis and if you know the approximate process of application and removal, it will be much easier to deal with the other seals - but there is too much at stake to be paranoid and reduce the chances of a coup due to early detection. After all, I doubt the White-Eyes will have a Fuin player of my level, since Uzumaki Mito doesn't train just anyone.
