"Yan'er, when I go down, you and the fleet will hold this place together, and don't let anyone get close to here."

"Don't worry, wrap it up on me!"

Nodding to Emperor Yan, the Yellow Emperor's body suddenly turned into a ray of golden light, fused into his body, and then the tall giant god soldier jumped into the boiling lake and swam towards a large hole located in the deepest part of the lake. The heat that boiled the entire heavenly pool came from that place.

According to the official figures, the maximum depth of the Heavenly Pond is only 373 meters, but in reality this depth only refers to the distance from the surface of the lake to the entrance of the cave. Further down is a vertical shaft 300 meters in diameter and hundreds of kilometers deep, leading to the surface of the Earth's mantle, where ancient people have left the largest "ruins" of human discovery today.

In a period of history that humans don't know, ancient people, who were originally organic lifeforms, did many, many things that seemed crazy to humans in order to obtain more energy. And the "super energy project" that runs through the entire Gendaya civilization can be said to be the culmination of "tricks and deaths".

As the name suggests, "super energy" is a device that can produce an astronomical level of energy. The last generation of super energy of the ancients was the "soul energy" that pushed their entire race to the peak, but unfortunately their entire race eventually died suddenly at the peak, and the first generation was a more down-to-earth "earth nuclear energy".

The vast majority of human beings living on Earth do not know that on the mantle 150 kilometers deep under their feet, there is a huge ancient human device called "earth net" by the high-level officials of various countries. The device is made up of a large number of black pipes with a diameter of about 100 meters. The mantle covering the entire planet has a total length of more than hundreds of millions of kilometers.

Mankind in 1863, by a man named Otto. German professor of geology at Rieden Bullock. By chance, a platform was discovered in the crater of Snæfell, Iceland. In line with the spirit of "death" inherent in human beings, the other party accidentally activated something in the process of research, and then this extinct volcano erupted!

Since then, extinct volcanoes have been revived in various parts of the planet, and humans have detected a special radiation wave near these volcanoes. And those countries with S-class giant god soldiers asked these old monsters through guò and learned that this should be a phenomenon caused by the activation of the earth's nuclear energy extraction device, which has been shut down for countless years.

The "ground net" device laid by ancient people on the earth's mantle. The main role is to absorb the heat energy of the earth's core. At first, the device was passive, with the core releasing and the network absorbing, but as the energy needs of ancient people increased day by day. Not only did they go to other planets to lay "ground nets", but they even upgraded their devices from "passive" to "active".

But it didn't take long for the ancients to discover that excessive absorption of the earth's nuclear energy would weaken the planet, and overexploitation would even lead to the death of the parent planet. Coupled with the discovery of a new generation of super energy at that time. Therefore, the ancients stopped the exploitation of earth's nuclear energy. However, the "ground net" has not been dismantled, and it continues to remain underground for execution from time to time.

At present, humans have only accidentally touched the start switch of the extraction device, but the key energy conversion device has not been found. This directly leads to the fact that all the absorbed core energy volatilizes into the surface crust after overflowing, and the volcanoes on the surface of the earth are too active. And even if humans have a transformation device, they will not be able to use it at all based on their current needs.

It's like giving MP3 a nuclear power plant, and it's a waste to think about it!

The Yellow Emperor after entering the passage. Against the surging heat from below, it continues to advance deep underground.

This channel is located at the intersection of many underground water sources in Changbai Mountain. As a result, there is an abundance of water, and the heat from the network boils the water from the surface and is then pushed up to the ground by the water vapor that rises from a deeper level. Therefore, after the Yellow Emperor descended to a certain distance, only the upwelling water vapor was left around, but there were some very troublesome things wrapped in it.

When the Yellow Emperor descended 70 kilometers, she sensed several large objects in front of her that were climbing up the walls of the passage. The opponent's body is about 30 meters long, about 7 or 8 meters in diameter, and the appearance is a bit like some kind of super huge insect.

The giant insects hacked to death by the Yellow Emperor are called "volcanic fleas", which are a kind of "mantle creatures" that are not known to most people, and are known as one of the three mysterious creatures on the earth along with deep-sea creatures and atmospheric creatures.

Originally, these giant creatures lived hundreds of kilometers underground, and the water from human wells living on the surface of the earth did not interfere with the river water, but with the activation of the ground network, these creatures were driven to the surface by the energy of the earth's core. , which once caused a lot of trouble to mankind. But fortunately, when they came up, the human armament had completely entered the age of firearms, and even if the giant god soldiers were not dispatched, the general heavy firepower could also level these behemoths.

After piggybacking on some of the mantle creatures that the ground forces had difficulty dealing with, the Yellow Emperor, who had limited time to move, no longer entangled with them and accelerated his advance underground. At this time, she suddenly thought a little bit about Zhao Jian, if she brought him over, her time limit for action would be greatly extended. But the Yellow Emperor felt that since she had promised the other party to keep it a secret, then she should keep her promise and not dismantle Zhao Jian before he did evil.

Soon the Yellow Emperor passed through the passage and entered an open area, below which was a large boiling magma sea, the entire space was too large to be seen at a glance, and two interlaced black giant cables lay across the magma sea.

The Yellow Emperor looked around, and the detection situation told her that the area of this underground cavity was twice as large as the last time she came down, and these two ground network cables were still continuously releasing the absorbed earth core energy. If it continues like this, it won't be long before the entire Changbai Mountain has the possibility of "sitting and sinking".

"Damn! It's getting stricter and stricter! ”

Looking at the situation in front of him, the Yellow Emperor fell into a deep thought. The entire network was originally only activated in Iceland, but after it was activated, the entire control platform was swallowed up by the gushing magma, and it was impossible to close it again. The absorbed core energy could not be immediately transmitted from the extraction device, so it spread along the lines of the ground network to the surrounding areas, activating these areas as well.

In less than 100 years, more than 80% of the ground network has been activated, and the rate of spread is getting faster and faster. If this continues, it won't take a few years for the entire earth network to be fully activated, and then humans may not be able to continue to stay on this planet, time is already imminent! (To be continued......)
