The water was rising quickly, soon reaching Gu Fan and the others' calves. If things continued this way, the entire chamber would be flooded and they would be in real trouble if they didn't figure out a way to get out soon.
Gu Fan gritted his teeth: "If I'm not mistaken, this is the water from that underground river. Does anyone here not know how to swim?"
Luckily, Du Jun, Lu Yi, and Xu Haowen could all swim. However, it was unfortunate that none of them were strong swimmers, and how long they could swim remained uncertain.
As the water level continued to rise, Du Jun suggested, with the help of the water's buoyancy, they should try to return the way they came.
To this, Gu Fan shook his head: "I'm afraid the exit might be sealed. Then we'll have trouble escaping."
