After diving into the water, Su Wen watched Luo Yang move ahead like a mermaid, gracefully kicking her long legs. With Luo Yang breaking through the water's resistance, Su Wen found it easy to follow closely behind, and the two quickly descended to the riverbed.
It was then that Su Wen realized that the small river was actually over four meters deep.
Next to the riverbed, on the river wall, Luo Yang quickly located a small hole following the direction of the eddies. She used the sturdy waterproof flashlight in her hand as a rod, stirring inside the palm-sized hole, loosening years of accumulated silt. As it dispersed with the water, an opening large enough for an adult to crawl through was revealed.
Unable to speak underwater, Luo Yang pointed at the dark depths of the hole and then swam in first.
However, Luo Yang clearly hadn't expected the passage to be that deep.
