Chapter 150 - Unknown Civilization

After giving himself five minutes of rest, Zero still struggled to get up, no matter how tired and tired he was. It seemed that this underground space was safe for the time being. However, there were seadragon fishes in the water. Who knew if there were any other mutated beasts in the underground space. Zero did not dare to be careless, but before he left, he still had to deal with his wounds.

He looked at the hole in his right chest that had turned white from the water. He was glad that the Parkland assassin had used a standard sniper bullet instead of an armored or explosive bullet. Otherwise, his injuries would have been more severe.

He first evaporated the vapor on his body with the high-temperature ability of a fire element, and then took out the last of the disinfectant spray from his military backpack to disinfect the wound. Without any extra bandages, he had no choice but to take off one of the sleeves of his tactical uniform, and then cut it open with his military knife, tying it to his body so that the muscles around the wound wouldn't tear due to his body's movements. After doing all this, Zero lifted the light stick and aimed it into the darkness of the cave.

From time to time, mutated insects the size of pinky tails drilled into the wet cave. These small insects ate mostly mud. However, there were even bigger worms that he could use as food. As he passed, he saw a few arm thick thorns appear from some of the holes in the cave, and then he would swallow these worms up.

The mutated insects that were hidden deep underground were very sensitive to light. The dim light from the light was as eye-catching as sunlight to them. Sensing the source of the light from the glow stick, the Impaling Warriors returned to their nests, allowing Zero to drop the 500 revolver and move on.

The deeper they went, the more branches the cave grew. It looked like the lair of some large earthworm. In this labyrinth of caves, if they went the wrong way, they might never get out. But there was a breeze in the cave, and a small flame rose between his fingers, judging his path by the direction in which it swayed. In this way, the labyrinth of caves could not hold up to zero, and the wind guided him faithfully in the right direction.

He silently calculated his steps. When he counted to 1045 steps, everything in front of him suddenly became clear.

He had emerged from a complex cave on a side road, but before his eyes was an even larger natural cave. It was hard to tell how big the cave was from the faint light emitted by the glowing stick. But after ten minutes or so of walking along the edge and still not seeing the end, he had to give up. Judging from the occasional whistling of the wind in the cave, this place was probably the size of a football field.

Zero raised the glow stick again, and in the dim yellow light he saw the rocks above him, and the irregular stalagmites. The width of the cave was extremely wide but the height was limited. It was only about five meters, which created an abnormal feeling of oppression. From time to time, cold droplets of water would drip down from the stalagmites. In other words, there was even underground water flowing on this layer of stalagmites.

If there was a current, there would be an exit, but the problem was how to penetrate the rock layer. He walked aimlessly into the depths of the cave, hoping to find some sort of opening. However, he didn't find the opening to the water. Instead, he saw the reflection of metal in the glow of the glowing stick. Where did the metal come from? Could it be a mine? Zero thought.

The metallic reflection came from the darkness in front of him, and he quickened his pace. This time, he did not walk very far. After about ten meters, his foot landed on a strange metal object.

Zero crouched down. This piece of metal was only a thin piece, but it had been molded into the shape of a feather. There was a corrosive technique on the metal piece that carved out lines similar to circuit crystal plates. Embedded into the end of the piece of black and purple crystal stone was a proof that it was not a natural product.

When the light stick approached the metal plate, Zero could clearly see the crystal embedded in it suddenly flash with a faint light. Following the flow of this ray of light from the patterns on the metal plate, the entire plate slightly trembled as if it was alive.

Zero looked at the light source with surprise. Judging from the light source of the glowing stick, the black and purple crystal was similar to a solar panel. It could absorb light sources and use them as energy sources. Judging from the vibration of the metal plate, this feathery object contains three systems: light source absorption, energy conversion and driving.

The use of solar energy as the main source of energy, as well as its conversion and driving processes, is not impossible to achieve at today's technological level. But that required a system of units and structures, and no matter how elaborate the processing was, it was impossible to organically combine the three systems into a thin sheet of metal no more than five millimeters in length and no more.

Judging from the thick layer of dust on the metal sheet, it was unknown how many years it had lain in this dark cave. As far as he knew, among the research results of energy made public by the Dark Council, the most representative magnetic energy units could only sustain about ten years' worth of energy movements on their own without any extra energy supply.

However, this piece of metal, Zero believed that it would definitely last more than ten years or more in this cave.

So, what kind of organization did it come from? Was it a product of the new era, or was it the crystallization of technology from the old era? However, he believed that even if the resources of the old era were plentiful, there wouldn't be enough technological support to produce such thin metal sheets.

As they moved forward, more and more of these metal plates appeared. They were scattered all over the place, like the wings of some prehistoric bird.

Finally, when they were a hundred meters away from the first piece, Zero stopped and a huge wing covered with the same metallic texture dropped limply to the ground. The metal sheets fell off from this wing, and Zero could even see the metal frame after the piece fell off. This imitation of the wings of a bird made of metal, made Zero think of a noun.

Bionic technology!

Although biomimetic technology had been developed in the old era, it was still unable to reach the technological level of this metal wing, let alone the exquisite system on that piece of wing. Without giving much thought to the limited number of light rods, he took out the rest of the light rods. After making them light up, Zero threw a few of the light rods in different directions.

Thus, an unbelievable scene appeared before his eyes.

What appeared before Zero's eyes was a strange looking flying machine. It was the size of an old ship, with a U-shaped front end and a streamlined rear end. The entire aircraft was covered in mud, and a portion of it was stuck in the layer of rock above. It was as if it was stuck in a cave.

There were three enormous metallic wings on each side of the aircraft, and they were all hanging limply to the ground. However, after coming into contact with the light from the rods, the light absorption system on the metal wings began to move naturally. However, the wings only vibrated slightly before quieting down. At the same time, all the light rods of zero had been extinguished. That was because the light source had been absorbed by the metallic wings.

With the last glow stick in hand, Zero carefully distanced himself from the wings, so that even the last of the light source was gone.

He was almost certain that neither the aircraft itself nor the metal wings were the product of the new or the old. So which civilization does it belong to?

Was it an alien civilization? Or some unknown civilization relic in the history of Earth?

For a moment, this airship attracted far more attention than it did when it left the cave. It was as if he was standing in front of a huge mystery, and Zero could not wait to solve it.
