The supervisors of the Blood Devil army did not intend to send the vanguard troops to their deaths. Instead, they wanted them to use their bodies to stop the flood to buy time for the later troops. The core powers in the Blood Devil army had started to dig canals to release the floodwater.
They were extremely fast as they used their bodies as tools. They would punch the boulders in front of them.
The seven vanguard troops gathered. They did not dare the betray the willpower of the supervisors. In a short one minute, walls of bodies were formed.
When the flood crashed into the wall of bodies, some Blood Devils were instantly washed away. But after the flood passed through several walls of bodies, the collision gradually grew weaker. When the flood reached downstream, the collision had grown much weaker!
Needless to say, the wall of bodies was useful. It helped to buy time for the later batches of the Blood Devil army!
