The Yongxing Empire does not require actual cooperation with others.
They only need other challenger teams to share a bit of the pressure from the gatekeepers.
Even if only a dozen or so powerhouses from the Yaoxing territory are present, it is enough for them to charge in and out of the gatekeepers' army repeatedly.
This is the power of the Perfect Domain Realm.
What do you have to stop it?
Moreover...
Yaoxing Lian lives up to his name, dazzling on the battlefield.
He is also the absolute leader of the Yongxing Empire in every sense, with strength and background capable of subduing other lords or division generals of territories. His radiance illuminates the land as other legendary powerhouses of Yongxing quickly gather around him.
Soon, Yaoxing Lian's team rapidly grows stronger.
A dozen people, dozens of people.
Two hundred, three hundred, six hundred!
