The canoe went into the cave along with the flow of the river.
They entered through the cave's opening, which was extremely narrow.
Darkness descended immediately. The light that shone in through the cave's opening soon disappeared, and everywhere was pitch dark. The canoe was dashing forward at an extremely fast speed towards the unknown front, and occasionally changing directions when it bumped into the cliff walls.
There was complete silence; only the sounds of rushing waters and the canoe hitting the walls could be heard. It made them a little fearful.
After moving forward for a while, the water slowed down, and the gushing sounds became softer. The canoe slowed down too.
Meanwhile, there were flickers of light floating around on the water surface in the distance.
Amy suddenly pointed upwards with surprise, and said, "Look, it's stars!"
Everyone looked up, and their eyes lit up.
