After hearing Senior Brother Zhao's words, Yunxi understood what he meant. They would break them one by one—first lure this pack of Sand Rats into the formation and eliminate any disturbance outside, lest they attract even stronger Demon Beasts.
Then they would clear out the Sand Rats section by section. The four of them should be able to handle the first-tier Sand Rats, though the expenditure would be considerable, so they had to work together. Otherwise, once their Spiritual Qi ran dry, they could easily be swallowed whole.

"I understand Senior Brother Zhao's plan, but to trap a second-tier Sand Rat, we must use mid-grade spirit stones. Otherwise, once we let it into the formation, if it starts charging about wildly, my formation disk won't be able to withstand it. We won't even have room to catch our breath, and we'll be dragged into a bitter fight."
