The climate of the Ancient Sea is warm and comfortable, without any chill, yet it feels very pleasant.
"Ah Kun, what is that?"
Ruyan pointed to a black hole in the distance and asked Ah Kun, who was steering the boat.
"To answer Madam Luo, that is the Mo Cave, one of the four mysterious caves of the Ancient Sea."
"Mo Cave? What's inside the cave?"
"There is nothing inside the cave, it's just very, very dark."
Ah Kun answered truthfully.
Ruyan squinted slightly. Very, very dark? Could it be a coal cave?
In this era, no one uses coal yet!
"Ah Kun, row us to the Mo Cave, let's go take a look."
"Yes, Madam Luo."
Obediently, Ah Kun steered the boat towards the Mo Cave. Ruyan and Luo Shunchen disembarked and walked towards the cave.
It was really dark, with a strong smell of coal soil, assaulting their noses.
Ruyan could immediately determine that this Mo Cave was indeed filled with coal.
