Zhang Heng climbed down the uneven wall toward the bottom of the pit. As he had to maintain his weight balance during the climb, he couldn't move too quickly. The 30-meter-distance wasn't too great either, and he quickly reached the bottom of the pit. After taking a quick look at his surroundings to ensure no danger, he waved his flashlight upward.
This was the signal that Zhang Heng and Ma Lu had agreed on. When Ma Lu saw the light from the flashlight, he knew that Zhang Heng had landed safely. He then tossed his bag down.
Zhang Heng heard the sound of falling from the top of his head. He moved aside and waited for a muffled sound before his bag fell to the ground beside his feet.
Zhang Heng picked up his bag and dusted it off. Only then did he start to look at his surroundings carefully.
