After confirming the plan, the group didn't start immediately but observed the nearby terrain and formulated various strategies, because once they encountered a tier-five enemy, they would definitely lack the ability to fight or the chance to flee.
So they had to set a plan from the start and keep themselves hidden.
After observing the nearby situation, Du You and the two sisters started to fight. "There are quite a few animals in this canyon, which makes it a good breeding ground. Next, we'll leave some corpses here, just piling them up in this place will do."
While speaking, they had already started hunting down some creatures stealthily. Worried about causing too much commotion, they didn't even touch creatures of tier four or higher.
Once enough corpses had accumulated, Du You waved his hand and threw out a Putrid Insect Mist, then he and the sisters quickly moved away from that place. They stopped at a safe spot they had scouted earlier.
