Saving souls taken away by the Shinigami was simple.
Summon the Shinigami, then control it and make it cut open its own stomach.
But in that case, the person controlling the Shinigami would have to cut open their own stomach as well.

It was said that one ruthless fellow had committed seppuku one afternoon and did not die until nine the next morning, lasting a full nineteen hours. That record remained unbeaten to this day!

However, when she cut open the Shinigami's stomach, she found that it had swallowed rather a lot of souls.
After spending some time finding her target, she controlled the puppet to release the Reaper Death Seal.

The Third Hokage and the Yin Chakra Nine-Tails were both in her hands.
Hinata planned to use that half of the Nine-Tails to fill the Ten-Tails' gap.

In the past, Hinata would have sent the Third Hokage's soul to the Pure Land of the Underworld.
But now that she suspected the Sage of Six Paths' motives for remaining in the Pure Land of the Underworld were far from pure, sending the Third Hokage's soul there would be like pushing him into a pit of fire, wouldn't
