Behind the valley in front, in the dim light, you can see that there is a rock wall, and under the rock wall, half-blocked by a mass of dark bushes, is a dark hole.

In a place in front of the entrance of the cave, I don't know what is bursting small fireballs.

These small fireballs were driven by the air current, rolling all over the ground, and the situation was particularly strange to watch.

"There's a cave,"

Bo Junxiao also saw it, "The thunder and lightning over there are very dense, and they are tiny ball lightning. ”

"No, listen!"

In the crackling noise of the fireball, Yan Mu held Bo Junxiao's hand tightly, "Listen! ”

Bo Junxiao narrowed his eyes slightly, and released his soul power slightly.

After knowing that after the soul power is strengthened, he may have that extreme desire to control Yan Mu, under normal circumstances, he will control the number of times he uses his soul power.

"Someone!"

After a pause, Bo Junxiao opened his eyes suddenly, "There are people in that cave!" ”

He could hear the sound of some beating, which was not the sound of nature, but with some kind of artificial law...... Morse Code?!

Someone is using Morse code to pass on a distress message!

"Could it be Nick's big brother?"

Yan Mu's eyes lit up, "Quick, let's go over and have a look-"

"Wait!"

Bo Junxiao grabbed her.

Yan Mu looked at Bo Junxiao suspiciously.

Bo Junxiao didn't explain, leaned over the ground to find a large stone, and then threw the stone into the dense and rolling miniature ball lightning.

"Bang!"

There was a loud bang, a blinding explosion.

Yan Mu subconsciously covered his eyes.

When she opened her eyes again, she couldn't help but be stunned. In front of the cave, a large crater was blown out, which shows the power of the explosion just now.

It is conceivable that if you rush straight over, the consequences will be unimaginable.

"Let's go!"

This time, Bo Junxiao grabbed Yan Mu and said, "Follow me!" ”

Yan Mu quietly stuck out the tip of his tongue, and took advantage of the gap where those ball lightning bolts appeared again, and rushed over quickly following Bo Junxiao's movements.

"Brother Xiao!"

As soon as he entered the cave, Yan Mu was excited again, grabbed Bo Junxiao's hand and shook it, "The jade mine should be here!" ”

Outside, she could only feel a slight fluctuation of Yuze's power, and as soon as she entered the cave, this fluctuation was obvious, indicating that she was not in the wrong place.

"Find someone first!"

Yan Mu suppressed the excitement in his heart and said.

Bo Junxiao motioned for her not to speak, found a small stone from the ground, and knocked it on the stone wall of the cave a few times according to a certain pattern.

I didn't see him very hard when he knocked it, but somehow there was a kind of ingenuity, and the sound sounded far and long.

Yan Mu was curious and wanted to ask what he was doing, but saw Bo Junxiao make a silent gesture at her again, and quickly nodded and covered his mouth.

An intermittent response was soon heard.

Bo Junxiao immediately knocked on a long list.

A moment later, I heard a little more trivial response.

"He's wounded, down there. There were three of them—"

Bo Junxiao frowned and listened, translated to Yan Mu, and seeing that Yan Mu didn't understand, he added, "Morse code, a signal code." ”

"Oh!"

Yan Mu was surprised, "How can you understand this?" ”

Bo Junxiao raised his eyebrows, looking at her and smiling: "I know that there are many more, including all kinds of ...... You can try it in the future. ”

Yan Muzheng was so excited that he didn't touch the meaning of his words, and hurriedly said, "Morse code, it seems to sound very lofty...... It feels like watching a spy movie, is it difficult? Can you teach me? Can I learn? ”
