Su Jingxing rested for a moment, then stood up and circulated the Six Comets Records to deduce the exact location of the Half-Demon Overlords of the three kinds of demonic creatures—— Bone Demon, Snake Demon, and Sword Demon.
There were many Half-Demons, but there were limited Half-Demon Overlords.
In total, there were only about 50 Half-Demon Overlords.
Su Jingxing had to get rid of these 50 Half-Demon Overlords no matter what.
With the three Ancient Demons gone and all the Half-Demon Overlords wiped out, the plan of the demonic creatures to invade the surface would end before it even began.
The remaining Half-Demons were killed whenever he encountered them. Those who didn't meet him were lucky.
As for the demon slaves, there were billions of them. Su Jingxing really didn't have the strength or time to annihilate them.
Even if the demon slaves were killed, no Function Cards would be extracted.
