Klein swept away the Sand Algae on the ground and walls.
[Sand Algae: A type of algae that grows on the sand. It can be eaten and tastes slightly sweet. It is rich in trace elements and grows quickly. Often, seeds are planted and a patch will grow the next day.]
"Not bad. At least it can be eaten."
"It can be considered adding a variety to the type of vegetables."
Klein looked around. There was nothing else he could collect.
The calls by his ears had already stopped for a few minutes.
"It probably gave up when it saw that I didn't respond."
Klein took out his shovel and geomagnetic crystal ball and prepared to head to the next catacomb.
The arrow in the geomagnetic crystal ball pointed diagonally to the right.
Klein put away the crystal ball and looked at the five directions one by one.
