Snow pushed them away at a critical time. They were careless because Snow said that the ruby plum blossom tree was damaged, and her soul hurt so much that she asked them to go and look at the tree if that person's partners went and destroyed the tree.
So some of them separated into two groups. A group ran to see the ruby plum blossom tree, and a group stayed with her to deal with that person.
If the plum blossom tree is damaged, Snow's body will be damaged too. The ruby plum blossom tree was like Snow's heart, blood, bone, skin, and soul.
The result was that Snow pushed several of them who stayed with her away as she dragged that person into the Silent Of Everlasting Death Dimension without hesitation.
"Snow dragged that person into the Silent Of Everlasting Death Dimension, hoping to kill that person with her, and even if she cannot kill that person, I knew that she would try everything to imprison that person in that space!"
