Hu Li was beaten beyond recognition by Demon King Ao and fell unconscious.
Demon King Ao merely instructed the demonic beasts to throw him aside and didn't specially send demonic beasts to watch over him.
After all, this was Hu Li's territory. Demon King Ao had come alone without any subordinates.
Of course, the tiger demon race was originally a vassal of Demon King Ao. It was only natural for him to instruct Hu Li's subordinates.
Now that he had left, the other Demon Kings were still discussing how to divide Hu Li's territory and had yet to come over to deal with him.
This gave Yin Chengshan a chance.
Zhou Shu had previously arranged for Zhang Chunlin and the others to leave, while Yin Chengshan, who had transformed into Yao Aotian, stayed behind.
The only reason he stayed was to wait for Zhou Shu to leave. He would find an opportunity to move the forging materials that Zhou Shu couldn't take away.
