The beginning of a huge plan

Although the expansion of the Earth had ended, Lilith had told Bai Zemin that there was a possibility that when a second phenomenon occurred in which the sky would darken as a result of the great charge of mana that would be injected into the Earth, the world would expand further again. 

In addition, the surroundings were not at all safe at the moment and therefore Bai Zemin ordered that the survivors were strictly forbidden to get out of the vehicles they were in. He also ordered to completely quell any attempts to cause disturbances but to treat those who acted appropriately with respect and politeness.
