The four demon kings were terrified, for they understood what was happening. Seeing that even Dragon Venerable was treating this Human Venerable respectfully, they knew Demon Valley had probably lost the battle just now.
"From now on, we don't have to worry about Demon Valley invading us," Qin Chen said to Sacred Lord Taiyi. "Demon Valley has already submitted to Taiyi Holy Land."
Hearing that, Sacred Lord Taiyi was shocked but soon overjoyed.
Demon Valley was a very powerful force of the demon race. Even if the holy land didn't have a strong foundation, it was much stronger than Taiyi Holy Land. Moreover, it even had a living Dragon Venerable.
If Demon Valley joined them, the overall strength of Taiyi Holy Land would be greatly improved.
The ninth prince was also surprised, for it had only taken the 17th brother not long to tame the five demon kings and the Dragon Venerable.
