They were all ruthless figures who had fought through thousands of battles and myriad tribulations, carving their way out over mountains of corpses and seas of blood.
Without battlefield instincts far surpassing those of ordinary people, they would have long since become dry bones in countless life-and-death struggles.
Thus, the instant they were sent flying, they already understood—the zombie race's defeat in this battle was set in stone.
Now that the Underworld's five Yamas had broken out of the formation, with two more Yamas at their peak guarding its interior, the combined power of seven Yamas was simply not something they could contend against at present.
If they insisted on fighting to the death, it was highly likely to result in the annihilation of their entire race.
And that was absolutely not something the four of them wished to see.
The zombie race had painstakingly built itself up for tens of thousands of years to attain its current position.
Previously, in setting up the Nine Nether Blood Moon Formation, they had already sacrificed the lives of hundreds of thousands of clansmen;
if this continued, even their very foundation would be shaken, their vitality nearly scattered.
They could never permit such losses that wounded their very origins.
Since brute force offered no hope, their most urgent priority was a decisive retreat—
that was the most rational choice at the moment.
Fortunately, the zombie race possessed extraordinarily tenacious life force.
Given time to recuperate, all these wounded could recover completely.
Then they could slowly restore their strength and accumulate their reserves, waiting quietly for the next opportunity to strike.
One day, they would surely seize control of the Underworld;
those lofty Underworld Orthodox gods would eventually become prisoners and slaves beneath their feet.
The four Zombie Kings were supremely confident of this.
