At nightfall, the demons who flew around the cave dwelling mountains returned to the cave one after another. At the foot of the mountain, a bonfire was lit every other zhang, and the night wind blew, the firelight stirred, and the shadow of the fire was reflected on the high mountain of the cave dwelling, and the shadow was full of shadows.

"Senior brother, their bonfire doesn't seem to burn wood, but black charcoal." Lu Ban put down the polar eyepiece and said to Sun Bin beside him.

"It's charcoal smelting again, and it's bonfire lighting, and it seems that the charcoal storage here is quite abundant." Sun Bin said.

The group took advantage of the darkness of the night to go to the cave dwelling mountain and quietly approached.

"There are campfires and patrolling demons everywhere at the foot of the mountain, how can we get close and find out?" He Guozhong said worriedly.

"Don't worry, these demons at the foot of the mountain will fall asleep in a short time." Liu Chunfeng said.

"Well, when they fall asleep, we'll quietly fly up the hill with our wings." Mulan Road.

"Don't fight with me, I'm going with the captain." Xiaozi Road.

"I'll go too." Hua Qilin Road.

"Let Xiaozi go with me, he has many experiences in the hole." Mulan Road.

"Do you hear that? The captain agreed that I would go, so don't follow me. Xiaozi said to Hua Qilin.

"Humph!" Hua Qilin glanced at the flute and turned his head.

About two hours later, the demons at the foot of the mountain snuggled up to the bonfire and stopped moving. Xiaozi, who was hiding behind the snow slope, frequently poked his head out and looked into the cave-dwelling mountains, and discovered this phenomenon.

"Captain, they've stopped patrolling, and we're ready to go." Xiaozi Road

"Well, okay, let's go." Mulan Road.

After the wings of the flight were activated, the two of them disappeared into the night high in the sky in a blink of an eye.

"We ascend to the top, and then approach the cave-dwelling mountains." Mulan Road.

"Okay." Xiaozi Road.

Hunting in the cold wind in the sky, Mulan and the two used all their strength to control the flight trajectory. Not long after, the two of them landed at the entrance of the first cave at the top of the mountain with difficulty, took out the Night Pearl, and cautiously walked to the depths of the cave.

Inside the cave, snoring came one after another, coming to them. The two walked to the cave for nearly half an hour before they reached the end of the cave, and they were all amazed in their hearts. It was another half an hour before the two of them came out of the cave.

Mulan activates her wings and flies into the air again.

"Captain, this is the first cave on the top of the mountain, and there are so many demons living in it, if you go further down, wouldn't there be more." Xiaozi sighed.

"Yes, the number of demons is far from what we imagined." Mulan Road.

The two continued to fly downward, landing in the cave on the left side of the second level.

The two took out the Night Pearl, and quietly probed inward through the dim blue glow of the Night Pearl.

The depth of this cave is a little deeper than the first cave. However, when they reached the end, there was a staircase leading to the bottom of the cave wall. The two of them walked down the stairs, and at the end of the stairs turned out to be a cave-dwelling cave in the third cave. Originally, the caves on each floor were connected, that is, in the interior of the cave-dwelling mountain, from the lowest cave, it was possible to reach the highest cave through the stairs connected inside.

The two flew out of the third cavern side by side, disappearing into the black night sky.

"No wonder they can climb to the top of the mountain to live, it turns out that the inside of the mountain is connected by steps, they are very smart!" Xiao Zi explained.
