Poison was a very terrifying thing. It had a shocking lethality to any life form. Rats were no exception. The problem was whether or not the rats would remain underground, waiting for the right moment.
The underground was not sealed, and the cave was winding, which would also greatly weaken the effect of the poison. In particular, what kind of poison could kill these rats?
These rats were fierce beasts, and they were obviously controlled by someone. How could they be fooled so easily?
"It's too dangerous to use poison! The ground here is fertile, and once the poison is used, the surrounding land will be destroyed. The price is too great. Moreover, the poison is long-lasting, so it is best not to use it. We can first use the Rune Bomb to blow up the tunnel and see if it can pose a threat to the rats. I'll think of another way." Li Xiang shook his head and did not choose to use poison.
