This small pool is located in the south of the Four Mountains. In order, it is the fourth mountain south of the Earth Valley. The exact geographical location should be the location to the east of the south.

The reason why Du Ke favored this small pool is because the small pool is like a pool in a fairyland, surrounded by layers of shrubs and trees blocking the sun, making the location of the small pool as dark as night. However, it is this dim condition that created the magic of the small pool. There seems to be some plankton in the pool water that emits light blue light, floating around with the pool water, and then plastering a light layer of light around the surroundings.

There is also a small flower with symmetrical leaves growing by the pond water. It is named "Glowing Epiphyllum" by him, not because it has any similarities with Epiphyllum.

Instead, the glowing cereus blooms beside the small pool, just like blooming at night, and can also emit a faint pink light, echoing the light blue light in the pool water, creating a dream like a fairyland.

Du Ke first checked the surrounding environment to ensure that there were no dangerous monsters entrenched.

This was the only way to visualize a test bench, and I took a little glowing water from a small pool, and used a microscope to observe the microorganisms contained in the water. I soon found that these light blue light emitted from a tiny algae, or to be precise, an organ in the algae's body. However, he compared the lightless water, there was also this kind of algae, but the algae did not shine.

After studying for a while, he made new discoveries. It turned out that these algae did not shine themselves, but could only emit a light blue light after eating some substance in the pool.

"Does this substance only exist in the pool?" Du Ke put away the test bench and looked at the small pool again. Xiao Tan was in a rocky area. There was a stream flowing in the upper reaches, and a river flowing slowly downstream.

The luminous algae is only in the small pool. Occasionally, a luminous pool water can be seen flowing into the small river and then quickly loses its light.

The stream upstream of the pool has not been luminous algae.

"Look upstream to see if it is the material flowing downstream." Du Ke carefully groped upstream with a heart of exploration. Along the way, he encountered a large tree surrounded by various withered vines, making the already dim forest even darker, almost as big as the night.

Soon Du Ke discovered a special passage, which was only the size of a person, extending along the stream, as if it was left by some animal walking for many years, and opened up between the withered vines and branches.

This passage extends to the middle of the mountain, and then appears in front of Du Ke’s eyes, a cave.

There are two passages at the entrance of the cave, one is the passage by the stream, and the other extends into the mountains. Du Ke saw that the stream flowed out of this cave. He shone the flashlight into the cave and found that the cave was not big. It is more appropriate to describe it as a deflated concave. You can see the walls of the cave deep at a glance. Apart from some high platforms similar to stone stalactites, there is no sign of a monster.

"Go in and take a look, what are you afraid of? I have teleportation magic!" After feeling the spiritual insect parasitized by the palm, Du Ke plucked up the courage to walk into the cave.

When he arrived at the stalactites platform, his eyes suddenly became shocked: "There are people here!"

The stalactite platform is naturally formed, but there are water pipes between the stalactite platform, which are carved from some kind of wood. Obviously, this cannot be derived from the hands of animals. These wooden pipes connect the stalactite platform one by one in order of height, and there are turbidities on it and it flows slowly. You can also see some residue in the liquid.

The shortest stalactite platform is the source of the stream outside the cave.

The tallest stalactite platform has an upside down stalactite on the top. I don’t know where the water source is connected to the top of the cave, so I flow through this stalactite into the stalactite platform, and then down step by step, flowing into the stream outside the cave.

"This..." Du Ke took photos around him vigilantly, but no other artificial traces were found. He didn't know whether someone used to live in this place, but now it is abandoned, or the people who live in it have temporarily left.

"If there are indigenous humans, what are they doing with this?"

Du Ke thought about it, and then he approached the stalactite platform and looked at it one by one. Only then did he realize something was wrong. The highest stalactite platform was like a large water tank filled with various fruits, which had rotted. The same was true for the second stalactite platform. Five or six stalactite platforms were all filled with fresh or rotten fruits, allowing the water to wash them away.

When the seventh stalactite platform started, there was no fruit, but there was a turbid liquid inside.

Until the next few stalactite platforms, the liquid gradually became clear.

"Is this... brewing wine?" Du Ke suddenly thought of a possibility, otherwise who would have put the fruit here and waste it. "There must be native humans living in this mountain. Their brewing methods look very primitive, and they should not have developed any higher civilization... And they must have been here recently, and there are very fresh fruits here, just like they have just picked them."

Paused.

He became suspicious again: "But something is wrong. These stalactites flow bit by bit, so where can we make wine? The wine that is brewed flows into the stream... Could it be that the shiny substances of the shiny algae in the stream are formed by the fermentation of these fruits?"

At this time.

Suddenly, some kind of animal cries sounded outside the cave. The cries were very messy, as if a large group of animals were calling. Du Ke felt aroused in his heart: "Can it be that the indigenous humans are back? I have to hide!"

He was not afraid of these "primitive people", but just wanted to observe secretly, so he quickly replicated the rocks on the cave wall, turned himself into a large rock, embedded it on the cave wall, leaving small holes for observation, and set up a night vision camera to shoot videos.

The messy screams are getting closer and closer.

Soon, the first indigenous human entered the cave. There was no light in the cave, and Du Ke did not dare to turn on the light, so he could only use a night vision device to observe. He soon discovered that these indigenous humans did not look like humans, but were monkeys or orangutans with hair all over their bodies - they could not be said to have hair all over their bodies, and there was no hair on their heads. The whole image was weird and ugly.

After these bald monkeys came in, they quickly ran to the stalactite platform, took out impurities precipitated in the water from the lowermost stalactite platform, and hurriedly stuffed them into their mouths.

One of the monkey kings, who showed their size, roared at the bald monkeys who were catching impurities, scaring the bald monkeys to flee in all directions.

The Monkey King was satisfied with the best stalactite platform, and did not have to catch impurities by himself. Instead, he asked a few female monkeys to retrieve impurities for it and then fed it bite by bit. When it was satisfied, the other monkeys came to eat. The monkeys did not eat too much, and each one took a few small bites. They lay on the ground with satisfaction in eating. Some male monkeys and female monkeys even started mateing like this.

"Hitting eyes."

Watching the monkeys do indecent things, Du Ke felt disgusted.

Especially the Monkey King, not only does he occupy a few female monkeys to mate, but when he sees other male monkeys being mate, he will also run over to drive away the male monkeys and complete the mating for the other party by himself. It is too lewd.

The entire unblocked conference lasted for nearly an hour. At the command of the Monkey King, all the monkeys walked out of the cave. Just when Du Ke thought they were about to leave, he found that they were going back. Each monkey was holding a pile of fruits in his arms, and under the command of the Monkey King, he threw these fruits into the stalactite high tower in an orderly manner - obviously, this should be their "wine-making" technique.
