Xiao Chen nodded his head at the center of their battle-line, which was unbreakable. No matter how many goblins charged in, they couldn't get past the forest of spears and their futile attempts costed them their lives.
His Rakshas were nearly impossible to be defeated if their opponents would assault them in the front, but an attack to their rears and flanks was a different matter. It's not like that they would a hundred percent be defeated but if they are assaulted from the flanks or rear, it would just mess their tight formation up and leave their ranks open for enemies to come flooding inside their ranks and mixing in with them.
"Charge harder!"
"More! A bit more!"
"Put all your strength into it!"
"Come on! Little ones... You almost succeeded! Come on!..."
"We are waiting... Hahahaha!"
