"If you throw in some branches or grass with a strong, irritating smell into the fire, the people inside won't be able to stand it."
Jiang Xuan nodded slightly. He had also tried smoking out big bamboo rats before, but the method was pretty ineffective.
When you light a fire at the cave entrance, most of the smoke doesn't go in—it drifts outside—so the bamboo rats inside never come out.
But Shi Chan had Jiang Xuan block up all the cave mouths on the mountainside, leaving only two openings—one at the top and one at the bottom. Then, he set the fire at the lower cave entrance.
With this setup, all the caves of the Giant Claw Tribe up on the mountain basically became one big chimney, and the thick smoke would be sucked through the winding tunnels, finally escaping from the cave near the summit.
Of course, even if you know the technique, using the wrong opening makes it pointless, so Jiang Xuan wanted to win Shi Chan—who knew the layout—over to his side.
