At this moment, in the dim cave.
The Great Elder was pouring some water from a water pouch onto his eyes, then he shook his head, indicating that this shouldn't be done.
Qing Chen knew that the Great Elder was using gestures to tell them the rules.
It's important to know that in the Taboo Land, discussing the rules is prohibited, judged by coherent language.
Once, someone illustrated the rules to a companion using drawings in the Taboo Land and wasn't punished, but anyone attempting to write them down got judged as having triggered the rules.
Even erroneous guesses were not allowed; if the rules judged you as guessing the rules, the entire Taboo Land would immediately become hostile towards you.
This is also one reason why Qing Chen learned to draw; previously, he had drawn on the ground to ambiguously convey the rules to Zard, Da Yu, and Chen Jiazhang, relying on everyone's understanding.
