Yuhara already understood what the Fourth Hokage was trying to do. If the Nine-Tails could be sealed back inside Kushina Uzumaki, then she could indeed survive. However, before doing that, the Fourth Hokage had to weaken the Nine-Tails to half its original strength, which meant paying an unimaginably heavy price.
The original outcome of the Nine-Tails incident had been the deaths of the Fourth Hokage and his wife, with Naruto becoming the Nine-Tails Jinchuriki. This time, the outcome would most likely be that Kushina and Naruto would become Jinchuriki together. The difference between these two outcomes might not seem that great, but the second could be summarized in another sentence—the Fourth Hokage had protected everything he wanted to protect.
Could this be considered an answer to the question Yuhara had once asked? However, such an answer still could not truly be called an answer.
The Third Hokage and the Anbu had fallen completely silent. After a little while, the Nine-Tails' enormous figure suddenly vanished.
At the same time, the barrier set up by the Fourth Hokage began to collapse.
"Stay here and wait for my order before coming over."
The Third Hokage said this, then rushed into the barrier.
"But..."
An Anbu shinobi was worried about the safety of the Third Hokage, who was acting alone. However, before he could finish speaking, another shinobi beside him stopped him. He merely shook his head slowly, signaling everyone to follow the Third Hokage's order.
Five minutes later, the Third Hokage's order arrived, and the Anbu shinobi began rushing toward him as well. When they reached the site of the earlier battle, they first saw a crying baby wrapped in swaddling clothes in the Third Hokage's arms. Then they saw the Fourth Hokage and his wife lying side by side on the ground.
