Another thing that needed to be set up was a barrier to enhance perception and detection.
It also had to be kept from linking up with the special passage inside the glowing pool. If it triggered a chain reaction in the formulas, it could cause the special energy inside the passage to erupt. That was absolutely forbidden. As a sealing master, Karin knew these basic taboos better than anyone. Sealing formulas and barrier inscriptions were the things most sensitive to any fluctuations in energy. Even though Karin knew nothing about this special space passage connecting the moon and the earth, she still understood how "sensitive" and "fragile" the formulas inside it were. Of course, that fragility and sensitivity were relative to fluctuations in energy.
The "passage" itself was still very sturdy.
At its very front,
based on the chakra probing that could penetrate inside,
its overall structure was extremely stable.
In theory,
passing directly through it wouldn't cause any impact or disturbance.
But to be on the safe side,
Naruto had called Karin over, so they could choose the safest way to enter.
Some risks were worth taking.
Others weren't necessary.
Besides, Naruto wasn't short on time. Staying here to sense the space formulas inside would also help him improve his understanding and mastery of Space-Time Ninjutsu. The Flying Thunder God Technique was still far from reaching its limits. Naruto's ultimate goal was an ability like Kaguya Otsutsuki's, which could create a unique dimension. The "Kamui Dimension," unique to the Mangekyō Sharingan Obito had awakened, could be considered a basic form of such an ability. Naruto also hoped that one day, he could use the Flying Thunder God Formula to create a unique "spatial form" of his own!
Of course, it was too early to talk about that now.
