With Wei Ying holding the lantern, the only source of light, Lan Zhan can see his targets in the dark. Chanting a mantra, accumulating sufficient chi, he strums his strings to send forth a shockwave to destroy his intended targets.

"You go and I'll follow you." With the targets destroyed, he bought them enough time to make their escape. "I think that's it. Let's go, Wei Ying. Just watch your step."

It's a matter of scooting low enough through the opening gap between the fanged teeth while avoiding the gap of acidic blood and stepping over.

Something good does come from being careful. A relief of fresh air and dry land greets them on the other side...and each other as they made it out alive.
