It's real hard to kill the gods…, Zhong Yue looked at the cracked egg and thought. Even for a god to kill the other gods, there was a great chance they would be able to escape, let alone Zhong Yue.
When Mother Da Zhen was exposed by Zhong Yue, she was hunted by over a dozen West Barren gods. But even so, she has still escape and survived until now.
After that in the Ancient Frozen Capital, when the other mother god was chased by the gods, Mother Da Zhen rushed over to rescue. And in the end, that mother god was killed, but she still managed to escape from the many Ancestral Star gods.
Then in that battle with the Xiao Mang grand ancestor, Mother Da Zhen was also one of the few that escaped alive.
One could really infer how hard was it to kill her.
