The method used by Xiaotian can be called the safest method. With this method, even if a Tailed Beast's Jinchuriki dies, the Tailed Beast will remain completely unharmed, though the Tailed Beast cannot die anyway.
The Jinchuriki will also be safe; even if the Tailed Beast is removed from their body, the person will not die from excessive loss of power.
However, Xiaotian had another plan in mind. He looked at the Tailed Beasts and said, "Actually, I am also planning to scatter you all out. Even though you might be captured by humans and sealed inside human bodies, you will still be able to help me gather intelligence. Therefore, I want to ask for your thoughts on this."
