Zhang Han walked very slowly inside, tinkering with some strange-looking things from time to time, but in the end he found nothing.

"Is it really just an ordinary cave?"

Zhang Han was also speechless. It took him so much effort to climb in, but it turned out to be just a naturally formed cave. He felt a little disappointed in his heart, but he soon put this meaningless emotion behind.

Keep walking around.

"Tick tock...tick tock..."

When Zhang Han walked to a certain location, he heard a very slight sound of water droplets. The frequency was very slow and it only sounded every two or three minutes. He quickly followed the location of the sound.

I saw a huge stalactite hanging upside down from the top of the rock. It looked like an inverted triangle as a whole, and the last part was only as thick as a finger, which looked very strange.

There is a large stone at the bottom. I don’t know how many years it has been there. It is full of traces left over by the years. There is a depression about half a meter wide on the top of the stone. There is half a tank of unknown liquid in it. The whole thing is milky white and looks like

There are no impurities at all, as if even dust can't get on it.

Those white liquids dripped down from the huge stalactites above, very slowly. Zhang Han felt it with his yin and yang eyes and found that there was a steady flow of energy flowing to the top of the stalactites, and then dripped into the grooves.

"What the hell are these liquids? Are they the essence contained in the mountain? Huh? Are there traces of something crawling here?"

When Zhang Han was full of doubts, he suddenly saw a certain spot on the stone. There seemed to be things as thin as fingers crawling on it. Judging from the traces, they should have been left in the past few days.

"Is it the trace left by that thing just now? Does it want to drink these liquids?"

Zhang Han originally planned to try these liquids with his fingers, but then he thought that it would be a bit risky to try here. Even though his body is very strange and he is not afraid of the poison of the long-tailed silkworm moth, it must be done according to the occasion.

"It's better to wait until we get out before trying again. With Sister Yun and two people protecting us, I feel much more at ease."

Although Zhang Han didn't know what these milky white liquids were, he still understood that the thief would not take it short. He still had to take what should be taken. If these things were of great use to him, he would probably regret it very much if he didn't take them.

Fortunately, the three of them had prepared a lot of things before coming. Each of them had a waterproof and fireproof special effect material bag. It was not big, but it could go to some special places, like the cave inside the waterfall.

Zhang Han poured out the contents of the waterproof bag, then squeezed the mouth of the bag tightly and began to pour the liquid into the groove. Now he only had this thing that could hold liquid.

Soon, the waterproof bag was full. After Zhang Han tightened the three-layer zipper, he hung it on his waist.

"Hey, it's a waste, only half of it is filled..."

Zhang Han looked at the remaining one-third of the liquid in the groove and smiled to himself. When did he become so greedy?

Zhang Han looked around again, planning to continue searching other places. Just as he was about to leave the stalactite, a subtle sound caught his attention.

"Zhizhizhi..."

This sound is like that of a bird, but it seems very weak.

"Huh? How could a bird come in here? Did I hear it wrong?"

Zhang Han looked around in confusion, and then the energy spread and soon filled the entire cave, but he didn't find anything.

"Squeak, squeak, squeak!"

Just when Zhang Han thought he had heard it wrong, the cry sounded again, this time it was obviously much clearer and had some urgency.

Zhang Han heard it very clearly this time, and he was very puzzled as to why his spirit could not detect its existence, so he could only look around.

The chirping of birds sounded one after another, sometimes urgent, sometimes weak, making people confused.

"above!"

Zhang Han listened carefully, and this time he finally discovered that the sound came from above him. There was nothing he could do about it, because the echo in the cave was very loud, so he had to distinguish carefully to find the location of the sound.

The top is about five or six meters away from the ground. Although Zhang Han can jump to the top in the fourth door state, he has no foothold and cannot stay in mid-air.

"Are you looking for me? If you're looking for me, won't you fly down on your own..."

Zhang Han murmured to himself, but in the end he decided to find a way to go up and have a look. He looked at the huge stalactite just now. There were many other rock pillars hanging upside down around it. It should not be a problem to bear his own weight.

"Whoosh!"

Zhang Han jumped fiercely, grabbed one of the rock pillars with both hands, and then climbed up without hesitation, quickly reaching the top.

He looked towards the location where the sound was coming from, and saw two rock pillars close together not far away. There was an object in the gap between them, the size of a fist, the whole body was colorful, and it was struggling.

, it looks like it's stuck in there and can't get out.

"What a good guy, you can actually ask for help!"

Zhang Han sighed in admiration, then climbed up to one of the rock pillars, and then stretched out his hand to carefully clean the surrounding area of ​​the thing. When the gap became wider and wider, the guy flew out with a whooshing sound, and was there.

It kept circling in the distance.

Zhang Han saw that it was out of trouble, so he jumped down from above. He looked at what looked like a bird in the sky, and the doubts in his heart deepened. There was a waterfall slowly blocking it. How could it get in?

"Did it fly in from somewhere else?"

As soon as this idea came out, Zhang Han shook his head and denied it, because the entire cave was in a sealed state. Except for the entrance, there was not even a small hole leading in.
