Standing at the entrance of the cave, suddenly, a helmet camera captured a very spectacular scene. Pen ~ fun ~ pavilion www.biquge.info

At this time, it is evening, the bats will come out of the hole in groups to feed, form the famous "bat dragon", the captain is magnificent, the situation of the bat out of the hole is very tragic, above the entrance of the cave, hovering the hungry eagle, thousands of bats are eaten, when the eagle is full and leaves, the remaining bats can safely come out of the hole to feed.

This tragic scene has been happening every day for thousands of years, with bats coming out of their burrows in flocks every evening to feed, and eagles hovering over the cave every evening on time, waiting for dinner.

Chen Yan prepared to go deep into the cave.

Chen Yan took out a flashlight from his backpack and entered the cave.

The cave is deep, and the air is filled with the smell of decay and rancidity.

Chen Yan marked a mark on the rock wall at each section of the cave, so that he could return to the surface the way he came.

After going deep into the cave for 2 hours, Chen Yan felt that it was hundreds of meters deep underground, and the cave was still extending downward, with more and more forks, and from time to time he could see vertical wells.

When he touched the fork in the road, Chen Yan followed a principle, entered the second fork road, and made an arrow to point to mark.

1 day later.

Chen Yan's location is more than 2,000 meters underground, the smell of corruption and rancid smell is gone, however, the temperature is very hot, the temperature exceeds 50 degrees Celsius, like a high-pressure melting pot full of lava, if you don't wear a special cooling suit, ordinary people can only stay here for a few minutes, Chen Yan ate a Yuan Qi fruit, and his body has been greatly strengthened, including, skin heat resistance, and he can stay here for a longer time.

Here, Chen Yan found many huge water crystals, stretching in all directions, Chen Yan seemed to be standing on a new planet, walking in it, he had to be extremely careful, if he slipped, the sharp, sharp water crystals could pierce Chen Yan's body.

This cave doesn't know where it extends to the depths of the earth, Chen Yan can't continue to go deeper, the deeper it goes, the higher the temperature, and if it goes deeper than 2000 meters, the temperature may reach the temperature of boiling water, if you don't wrap your body in colorful bubbles, Chen Yan can't stand such a high temperature, and besides, this cave extends in all directions, there are many forks, Chen Yan is easy to get lost in the cave.

It is possible that there is a complex, vast underground cave system beneath Africa, stretching like a spider's web across the continent and even, into the bottom of the Atlantic Ocean.

In the future, Chen Yan will come to this cave again to explore and explore the secrets of this cave. Flavi's notes record whether the two caves were connected somewhere underground in the caves where the remains of prehistoric human life were found.

......

Chen Yan has too much speculation.

You can't go any further into the depths of the cave, the temperature is too high, and it's easy to get lost in the cave.

Chen Yan prepared to return to the ground according to the arrow mark.

......

It took 2 days for Chen Yan to return to the surface and be able to breathe the air on the ground again.

Chen Yan continued deep into the jungle.

Day 47 of the jungle.

Chen Yan found a swamp flooded by the Blue Nile River, a large number of crocodiles, water pit vipers lived in the swamp, in the nearby jungle, found groups of baboons, and more importantly, Chen Yan found traces of human life, the branches cut with sharp weapons, the fracture was very smooth, and in the damp soil, people stepped on the footprints,......。

The Sacco people discovered Chen Yan and were extremely vigilant, curious, and even hostile to Chen Yan.

At this time, Chen Yan knew what to do.

Chen Yan smiled, took out a military dagger with a sheath from his backpack, and then pulled out the dagger, the dagger emitted a clear cold light, very sharp, Chen Yan took the dagger and gently cut it at a thumb-thick branch, the branch broke in response, the incision was very flat, in the jungle, there is nothing more useful and precious than a sharp dagger.

The three Sacco people stared at the dagger in Chen Yan's hand.

Chen Yan put the dagger into the sheath and handed it to them upside down.

“kljgofsf.” Indigenous language of the Sako tribe, a strong Sako man muttered a few words.

Chen Yan nodded.

Nodding and smiling are common expressions on the planet, and even a monkey can understand the meaning of these two expressions.

The Sacco led by the leader took the dagger excitedly, pulled the dagger out of its sheath, and gently wiped the blade with his thumb, but he didn't expect the dagger to be too sharp, cutting a cut on his thumb and bleeding, despite this, the Sacco man still had an extremely excited expression on his face, jklfdjfkfd, and his mouth was purring.

The other two Sacco men stared at the dagger with a look of extreme envy on their faces.

Chen Yan took out another bag of candy from his backpack and distributed it to the three of them.

If you don't understand the language, a gift is the best way to get in touch.

......

The three Sacco people relaxed their vigilance against Chen Yan, their hostility was gone, and they became very friendly to Chen Yan.

“kljhfkldn.” The Sacco man named Aya, who was at the head of the group, gestured with his finger to Chen Yan, meaning to take Chen Yan to his tribe.

......

Chen Yan followed the three of them, walked behind, passed through a jungle, and reached the Sako tribe.

The Kerch civilization is an extremely powerful and glorious civilization, but the Sacco people, the descendants of the Kerch civilization, live in the jungle, primitive and backward, and live in houses made of wood, branches, thatch, and mud, which are extremely simple, only a few square meters in size, but live with a family.

The largest and most 'luxurious' house in the Sako tribe is the house of the Aya family, who is the son of the chief of the Sako tribe, and the so-called "luxury" is similar to the cowshed in the countryside.

It is hard to imagine that their ancestors, the Kerch civilization, were able to build large-scale underground palace mausoleums hundreds of meters underground.

As soon as Chen Yan entered the Sako tribe, all the Sako people, whether they were old people, adults, or children, came out of the thatched huts in all directions, and surrounded Chen Yan with curiosity, vigilance, hostility, and other eyes, but they did not dare to approach Chen Yan.

The chieftain of the Sako tribe wore a fur coat of spotted beasts, a high crown of colorful bird feathers, garlands, and precious stones, and held a scepter to which a large ruby was tied with animal tendons.

“kldnfkldnfl.” Aya walked over to the chieftain's side, grunting.

The chieftain was very affectionate to his son.

“kldfndf.” The chief looked at Chen Yan and said.
