Grimm, Merlin, kun Zheng, Kelun, and the others who knew about the existence of space, and were all Zhao Hai's elders, appeared in the space.
They didn't know what had happened, but they heard from Laura that she had something very important and urgent to tell them. She asked them to put down their work and come to the space immediately.
Green and the others knew Zhao Hai very well. They knew that if it wasn't an extremely urgent matter, Zhao Hai wouldn't say something like that. So, when they received the notice, they immediately dealt with the matters at hand and entered the medium.
Now, Grimm and Merlin were mainly in charge of the blackearth wilderness. There were many races there, and there were many things to deal with every day. These things were naturally handed over to Grimm and Merlin.
