Qin Sisi and Ye You exchanged a glance, tightened their grip on each other's hands, and slowly stepped into the pitch-black mountain cave.
At first, there was only darkness ahead, so dark that one couldn't see their fingers even when stretched out. Ye You's extraordinary eyesight could only discern extremely faint shapes.
The two walked very slowly. After about a hundred meters, the surroundings suddenly became much brighter.
On both sides of the cave, the rock walls emitted a faint glow. The left wall radiated a pale silver light, akin to the luminous moonlight; the right wall shone with a brilliant golden light, resembling the dazzling rays of the sun.
The once completely dark cave was now illuminated by the glowing rock walls on either side, though not as bright as daylight, their vision was no longer hindered.
They carefully observed the scenery around them and noticed that both sides of the narrow cave had a half-meter deep and half-meter wide trench running along them.
