After the defeat, came the pursuit.
The Naga leader in command, following Lin Xiao's early instructions, focused on chasing and killing the most devoted Serpent Followers of the Snake People Demigod, paying no attention to the fleeing Frog People troops.
Even though they were now routed, as the indigenous tribe of the Snake People Demigod, their level of belief was the most devout. The current defeat was only temporary; if they were not completely eradicated, they might regroup and return later.
On the other hand, there was no such concern for the Frog People, who were merely a servant race of the Snake People and held a relationship of enslavement. Once defeated, without the Snake People to rally them, they were unlikely to return.
Whether it was during the decisive battle earlier or the subsequent pursuit of the fleeing Snake People, the Giant Clam at the foot of the Holy Mountain did not budge an inch, steadfastly guarding the Sanctuary of the Snake Man Demi-God.
