Under normal circumstances, as a dominator of the human federation, even if Huang Yuan went insane, he would never agree to the demands of the beast controlling forces.
The root cause of this incident was Liu Xi before being contracted by Fang Mu.
As an evil spirit, Liu Xi was manipulating Huang Yuan, and all the objectives were set to acquire the soul of death.
Under the drive of this purpose, the request Huang Yuan made with the various beast controlling forces was.
No matter how many people the beast controlling forces brought, if they wanted to deceive the Ten-thousand Nations Federation and enter the large ancient battlefield, they needed to provide four million soul of deaths.
The beast controlling forces agreed to this request without much hesitation.
Basically, every territory of the beast controlling force had large and small ancient battlefields.
Non-dark-element beasts rarely need the soul of death.
