During the transfer of the group to the new world...
The youngsters were put to sleep to avoid detection by the rest of the world. The world's rejection of powerful gods grows greater as one's social position falls. So Hei Jue and An Liang made arrangements for Ye Jingxia and Hei Anxia to enter undetected. As they enter the new world, they must be in a state of hibernation.
While entering the world, Ye Xiajie sensed a dreadful omen come over him. He surrendered his children to the two nearby systems. The next thing he knew, the space around him was swirling with someone whose mastery over space was attempting to confine him. Warden Lou and Warden Yun attempted to assist him, but the instant they formed such ideas, their souls were stuck and unable to move.
The God of Void knew he could not prevent it and commanded, "Protect the children! Your top priorities are Xiao Jing and Xiao Xia!" He disappeared on the spot as the swirl in the space disappeared.
