After breakfast, Hyuga Gen said goodbye to Karin and headed toward the meeting point.
His thoughts returned to Fuinjutsu.
He had experimented with the Black Lock Seal last night, and its effects had indeed been quite good. However, this Fuinjutsu could only be used on objects. Its main function was essentially to put a lock on an item—unless the seal was undone, the item could neither be opened nor used.
Furthermore, items sealed with this technique were difficult to damage. Whether burned by fire or drenched in water, they would not be harmed. That was another of its functions.
Thus, this technique could prevent private belongings from being opened and stolen by others, while also protecting them from damage. Hyuga Gen found it quite practical.
Of course, he had not yet had the chance to test those effects. After all, Karin's scroll was rather important. If something went wrong, he would have no one to blame but himself.
Next was the Contract Seal. As its name implied, this technique was used to seal contracts, mainly summoning contracts. It could sever the connection between a ninja and their summoned beast, preventing them from summoning it.
Of course, it did not only affect summoning contracts. Any connection established with a summoned beast through various means could be severed with this technique.
In Shippuden, the Fourth Hokage had used this technique to sever Obito's control over the Nine-Tails.
The last one was the Four Symbols Seal. The Four Symbols Seal could seal one thing inside another, just like how the Fourth Hokage sealed the Nine-Tails inside Naruto in Shippuden.
However, Minato had used the Eight Trigrams Seal in Shippuden. Although it differed from the Four Symbols Seal, the Eight Trigrams Seal was actually formed by combining two Four Symbols Seals.
