Li Yao looked ahead and immediately noticed dozens of excessively large tanks from the Giant Axe Tribe that had hundreds of drums placed on them. Countless brawny men, who wore nothing on their upper body, were hitting the drums hard!
The heavy drumming together with the fulmination of spiritual gas allowed the qi-trainers of the Giant Axe Tribe to activate their spiritual gas at the same time. Although there were only several thousand of them, they were marching forward slowly but surely as if they were an army of tens of thousands of soldiers!
Li Yao secretly commended them. The armies of the six tribes of Iron Plateau had their own distinctive characteristics, but all of them were well-trained and obedient to commands. Many of their battle formations were even more advanced than those of the Heaven's Origin Sector.
