Here is the requested translation:
Lu Yuan couldn't help but scratch his head—this damned [Monster], so greedy yet cowardly.
I really want to beat you into minced meat.
Nonetheless, the cost of this human expenditure can only be borne with gritted teeth. If you're not willing to use bait, how can you catch big fish?
"How much will it cost?" Lu Yuan asked.
"Hard to estimate, it depends on its level of greed. Actually, it doesn't require much; just give it a little bit every now and then, and it'll find it irresistible…"
"In this way, the mental network of eight million people could subtly influence the [Monster]."
Miss Conch said earnestly, "As long as we continuously and tirelessly influence it, it'll create an illusion—that humans are dangerous, and Green Grass City brings danger too. It will have to transmit us out. Maybe one day, we'll suddenly be thrown out. That's essentially the plan."
The method sounds crude, but it does have some feasibility.
