Then, with the shouts of prison guards, two hundred prisoners began to go to the corners and choose to wear metal bone auxiliary equipment suitable for their respective ones.

As the boss of the first canteen in the prison, Lin Fei came to this mining farm just to go through the motions and did not need to wear these auxiliary metal bones. However, Lin Fei also came forward to take a look at these old-fashioned metal bones.

These metal bones that have been used for many years are rusty, some are missing parts, and some are black blood clots. It is probably left by the prisoners and miners who died.

As imagined, this remote prison mining site would not provide them with any advanced auxiliary tools, which could have used metal skeletons for decades to enhance personal strength, or to enable them, prisoners to increase their mining speed.

More than ten minutes later, the prisoners who were wearing auxiliary tools took the old-fashioned lift under the arrangement of the prison guards and transported them to the underground mine cave and began to use mining tools to dig.

Lin Fei also followed the elevator to the mine, wore a helmet on his head, a cotton coat, and a breathing mask on his face. The underground mining site was covered by a high-power lighting system, and the brightness was no problem, but the smell was a little unpleasant. The temperature dropped instantly. Compared with the high temperature of desertification on the surface, the underground cave consisted of metal sticks and rocks, like a big maze.

The temperature of this huge underground crystal mine is as cold as a refrigerated cellar.

In the underground mine, every few meters, a metal pillar for support is erected. The gray-black rocks are mixed with white energy stones the size of fists. These energy white energy stones provide the unprocessed primary energy crystals required for the mecha and warship power system.

Lin Fei heard the introduction of the old prisoners who had come by dozens of mining experiences beside him. In the next seven days, these prisoners would eat and live underground to dig out the energy crystals in the cave.

These fist-sized white energy crystals can be exchanged for ten pieces of apples or cigarettes. If the blue energy crystal is excavated, one piece can be exchanged for a pack of cigarettes. If the higher black high energy crystals are excavated, congratulations, as long as the nail is as big as you can exchange for a cigarette or two bottles of high-end wine.

As for all the excavated energy crystals, when they go up from the underground cave in seven days, special personnel will conduct statistics and calculate based on the size and energy capacity. After returning to prison, they will be exchanged for corresponding supplies.

Lin Fei looked at the inmate who was working with tools beside him. He was a little bored when he was idle. Although he was the chief of the prison, he didn't have to go to mining. Even if he didn't work, his subordinates would respect him some crystals. No prisoner dared to offend him openly, as the boss he had created by making a fortune.

However, since he was here, Lin Fei also went to the pile of dilapidated spare metal auxiliary bones in the corner of the cave, found a useful pile that seemed to be used and put it on his body. Then he carried a small drilling rig on his shoulder and began to dig in the cave, putting the dug white energy crystal into a small backpack attached to the metal bone next to him.

After digging for a long time, Lin Fei found that this was also a technical job, so he had only harvested four small white energy crystals. There were old prisoners who often came by and had harvested more than a dozen white crystals. As for other high-quality energy crystals, in addition to experience, most of them rely on luck.

Anyway, Lin Fei, the boss of the first canteen, was not short of supplies, so he simply took off the auxiliary metal bones, jumped onto the creaking elevator, and went to the top of the mining site for some breathing.

After getting on the elevator and coming out of the mining cave, it was already night, and the night in the desert was very cold, and the temperature was lower than that of the underground cave.

Lin Fei saw two prison guards holding energy guns at the exit of the elevator, sitting on a stone, watching the night.

After seeing someone coming up from the elevator in the underground cave, both prison guards pointed their guns at the fence gate of the elevator. "It's me, Lin Fei, come up and find a place to sleep." Lin Fei said, throwing two prison guards a cigarette one by one.

The prison guard who was already familiar with the transport vehicle on the way to the road, did not make things difficult for Lin Fei, who was the chief prisoner.

According to regulations, ordinary prisoners can only eat and live in underground caves for the past seven days. However, as the prisoner boss Lin Fei, the two prison guards only turned a blind eye to Lin Fei. They had no place to violate the bottom line of the regulations. They did not want to challenge this human-shaped tyrant.

Lin Fei followed the direction of the two prison guards' fingers and found a small board house with simple wind-shielding no one to live in. Lin Fei, who had dug up the mine for a long time, slept directly on the metal bed of the small board house.

－－－

After five consecutive days, Lin Fei would dig some crystal mines when he liked to move. When he didn't like to move, he would come up to rest or walk in the open space in the mining site that was allowed by the warning.

On the sixth day, Lin Fei sat on a stone at the exit of the mining ground, looking at the metal structure of the surrounding mine. He thought that the remaining two days would pass smoothly, but suddenly heard screams from the underground mine caves one after another:

"Ah, help me, Big Snake."

"Dragon, black dragon."

"A dragon that can spit fire, my god, help me."

Suddenly, the prisoners cries out from the underground caves, accompanied by screams, and thick smoke also emerged from the exit of the underground caves.

The prison guards around were alarmed, and immediately took guns, and some went to control the energy turrets, all pointed the muzzles at the exit of the underground cave elevator.

The "cooling" explosions and collisions came out one after another, making every prison guard sweat. Facing the unknown monsters, these prison guards would not foolishly jump into the underground cave and joke about their lives, because the salary was not worth it.

I don’t know if it was because of the scramble between underground prisoners or the sudden appearance of monsters that were too terrifying, none of the prisoners in the underground cave could successfully start the elevator. However, the sound of help and wailing became louder and louder.

Lin Fei was glad that he was not in the underground cave and was about to stay away from the exit of the elevator to hide at the energy turret in the mining site, but the sound of the God of War pit system in his mind appeared again.

"Unknown dragon-type creatures were found in the underground mine. After being identified as a salon, the risk level was 177, and the scenario compliance was 81%.
