Retreat
Seeing the arrival of hundreds of new enemies, Hao Xuan's blood boiled and the will to fight turned from a small spark to a raging fire. He circulated Force Qi and Sundering Qi, "ASSAULT OF THE MAD GOD!"
His arms turned black and enlarged. Every single muscle in his arms contracted and then expanded with a force that was felt by even the soldiers around him. The air hummed for an instant.
"AHH!"
He lifted up the silver sword in his hand and threw it like a spear, nailing three creatures to a coffin a few dozen meters away.
"NO RETREAT!" he shouted at the men behind him and used Demonic steps to push further into the swarm.
Assault of the Mad God was the perfect technique to use in this situation. It didn't use any abilities that had a large area of effect so he wouldn't unnecessarily damage the surroundings. Just his raw power and speed were enhanced.
