The Hundred Faces Dragon had devoured all the flesh and blood of the Nine-Headed Heavenly Dragon. Furthermore, it also thoroughly analyzed its godhood. In the process, it didn't experience any resistance at all.
The flesh and blood attached to the surface of the Hundred Faces Dragon's body and coagulated into a gigantic silkworm cocoon that was red in color.
They took the red silkworm cocoon with them when they left. Gao Peng knew that this plane was already on the way to its demise. All the beings on this plane would face the omens of the plane's decay.
Thereafter, a portion of the monsters would leave this plane through the Spatial Tunnel or the Spatial Rift.
Some of them would die en route during the migration, but in the end, a few of the monsters would successfully continue the bloodlines of their own clans in an unfamiliar world.
The continuation of life was a different kind of miracle.
