Wang Zheng and Rara Durai were leading the Saruman Snake Army into the dense forest at the moment. They were going to lie in wait, waiting for the enemy's land troops. They didn't expect the enemy to be so cunning, a bombing followed by an attack by the super warriors. Their land troops remained undetectable.
Haddis' second phase of attack wasn't just to destroy the will of the Titans, he also wanted to lure Wang Zheng and the potential super warriors of Titan out. Didn't a Heaven-rank appear all those years back? These Titans weren't short on money. They might even be able to hire a few with money to get rid of Wang Zheng and the others. The army of Titan would then collapse. Intel told him that the army was very backwards and relied on a person's personal charm to govern the army. How could they still be doing something so primitive in this time and age?
