It was the first time the group saw this happen to a beast. After they had dealt with it, the Dragon's body split into thousands of light particles, and it slowly began to disappear. To the people at the scene who had been to the familiar world, it reminded them of what they had seen in the familiar world.
After waiting a while, there was nothing left of the Dragon, and the light particles had vanished right in front of their very eyes. Everyone stayed there in the crater for a moment, not saying anything. They were exhausted and had expended all of their energy and MC cells.
It was the same for Sil as well. He didn't hold back when using the MC cells he had gathered because he knew he couldn't take this battle lightly because his foresight had revealed what would have happened if he had hesitated any bit. The only ones left somewhat standing due to not doing much was Logan and Linda, who had arrived with Borden.
