In the quiet forest, He Tianlei led the people behind him and walked slowly along the railway track buried under the snow towards the small dirt bag in the distance. This place is far safer than everyone imagined, except for those two

Apart from the narrow mining rails running side by side, there are no other scary metal reactions underground.

Behind the crowd, the old hunter, who was hiding in the snow with a white cloth cover, put away his binoculars, spat at Shi Quan and others with a mocking look on his face, then got up and left the forest, turned around and walked towards Si, not far away.

Suburbs of Visayas.

During this week, these old men have been secretly following Shi Quan and others. Although they were almost discovered by the other party several times in the process, through the cover of the pine forest, the unfamiliar club members even connected with their

No shadow was caught.

The tracking in the past few days also allowed them to gradually figure out the pattern. Basically, as long as they did not approach the RVs that made him look very excited, they would not be discovered by the other party. Therefore, whenever Shi Quan and others entered the forest,

When looking for possible clues, they would stay very close, and sometimes they could even hear each other's conversations clearly.

Unfortunately, these colleagues from Russia actually spoke Chinese that they did not understand at all, which forced them to be patient and stay around the RV campground to catch the wind and cold.

But seeing them running through almost the entire forest and finally reaching here, the old hunter suddenly lost interest and decisively gave up the plan of tracking and picking up the missing ones.

Although Shi Quan and others knew that the dog-skin plaster that had been looming in the past few days was probably the old hunter. But since the opponent did not take the initiative to shoot, they naturally did not bother to make trouble.

Seeing that the mounds in the forest were getting closer and closer, more and more things that had not been discovered before in the drone were revealed.

Under the blow of the hot air blower, only the rusted iron chassis and remaining wooden boards of the mine car were exposed for about ten centimeters. After clearing away the fallen leaves and soil accumulated around it, you could even find the rusty crane's beak.

Hoes, rattan frames and even kerosene lamps with only their outlines left.

"This doesn't look like an ammunition depot." Shi Quan pointed to the raised mound directly in front and the remaining fireplace chimneys around it. "This looks more like a mine."

"But the Germans often hide things in the mines." Big Ivan was eager to try, carrying the engineer shovel, "dig it out and take a look?"

"Just rely on the small shovel in your hand?" Shi Quan teased Big Ivan, picked up the handheld platform and shouted, "Drive all the cars over, just follow our footprints."

"receive"

Haining responded. In less than ten minutes, the first batch of seven vehicles was delivered by Nenets' helpers. Then these people returned in a container truck and drove the remaining vehicles back.

It was almost equivalent to using these expedition vehicles to build a building bunker. He Tianlei hid in the three-proof cab and controlled the remote control excavation arm to dig out the foot of the mound that had just been blown by Deng Shuxiang with a hot air blower.

As the excavation bucket hit again and again, pieces of frozen soil mixed with humus and fallen leaves were peeled off, revealing the gravel underneath.

These gravels are more difficult to excavate than soil, and a bucket can only dig out pieces the size of a washbasin at most. In the end, He Tianlei had no choice but to use an electric drill to drill more than a dozen holes at the excavation site, and then filled them in.

A small amount of plastic explosives detonated, and the hard frozen soil was barely opened.

Large pieces of soil and gravel were moved aside, and the excavation bucket quickly dug along the buried railroad tracks. Gradually, He Tianlei dug out a hole at the foot of the mound that was more than a person tall and two meters wide.

.

As the hole continued to deepen and widen, it was not until more than two hours later that with a "crash", the collapsed hole was finally penetrated by a bucket.

Haining, who had been waiting for a long time, immediately put down his dinner plate and trotted out the back half of his precious maintenance truck from the dug mine.

When the excavation arm was folded and returned to its original position, Haining deliberately cleared his throat and pressed the remote control slowly. The alloy cover on the side of the vehicle automatically retracted, revealing an air vent with a diameter as large as that of a diesel engine.

.

He took out a gradually narrowing canvas roll from the wind vent and threw it to the entrance of the cave. Haining realized that no one had noticed this place at all. Even He Tianlei, who had been standing on the roof of the car to control the excavator, had already run away with a pallet.

Went to the dining car to get some food.

You can’t notice it, can you?!

Haining lost his temper, raised his hand and pressed the switch to adjust it to the maximum power. Suddenly, the rumble of a plane taking off resounded through the camp, and even the pine branches on the roof of the maintenance car were sucked down by the strong wind.

Everyone raised their heads and stared at Haining who was standing next to the maintenance truck in stunned silence, and then fled in all directions due to the rotten smell gushing out from the mine!

"Haining, close that piece of shit quickly!"

Shi Quan shouted at the top of his lungs. Unfortunately, Haining, who was standing next to the maintenance truck, couldn't hear his shout at all. He even thought his boss was praising him and patted his chest proudly.

"This idiot whose head is full of gears!" Gennia patted her forehead, squinted her eyes and covered her face, ran over and turned off the strong wind machine.

"Um...did I do something wrong?" Haining asked awkwardly.

"If there are paper artifacts or explosive tripwires down there, what you just did will ruin all your previous efforts."

Gennia gritted her teeth and shouted, Haining insisted on installing this fan before, just in case he encountered a closed environment that might need ventilation. Unfortunately, he was a mechanic after all, not a digger, and he didn't know what to do.

When is the right time to use this thing?

Shi Quan and others also ran over at this time, especially after seeing some moldy paper scraps falling from the entrance of the cave, the expressions on their faces became increasingly ugly.

"Um..." Haining realized at this moment that he seemed to have done something wrong. His dull head trembled for a long time before he quickly said an apology.

"never mind"

Shi Quan waved his hand, finally saving him face in front of Gennia, "Did you modify this thing? Why haven't I heard you say it before?"

Haining seemed to have forgotten what he had done in an instant, and said enthusiastically, "A turbo fan can output a greater air volume in a smaller space. If it is connected to a high-pressure nozzle, its power is no less powerful than a high-pressure water gun.

, the only drawback is that the noise is relatively loud.”

"Yeah...nice job"

Shi Quan pulled out the corner of his mouth and gave a dry compliment, and then the scene fell into awkwardness. Only Haining didn't know it, and was still chattering to show off his masterpiece to everyone.

Elena weakly patted Gennia on the shoulder and gave her a gloating look. The latter raised her thick-soled high-waist military boots and stepped on Haining hard.

When Haining jumped and screamed in pain, Shi Quan didn't bother to care. He did a lot of stupid things when he first joined the earth-digging party. As long as Geniya pays attention to family education, Haining will still be a good comrade.

"Although I got into a little trouble, I guess I can go down and take a look after such an incident." Shi Quan said as he walked back, "Elena, you and Nasha raise the drone and pay attention to the surrounding situation.

Xiao Ye is optimistic about the radar, and Xianyu takes the Nenets guys to stay on guard. Ivan, Lei Zi, the three of us can go down, and it’s enough to take Asak and Shuxiang with us."

"I can help too!" Haining couldn't hide from Gennia who was twisting his ears, so he simply picked her up by the waist and ran back.

"What weird things do you have?" Iwan asked gloatingly.

"It will definitely be useful for you!"

With Elena's help, Haining escaped from Gennia's clutches. He rubbed his ears, opened a small door next to the strong wind machine that was only the size of instant noodles, and pulled out a transparent plastic piece that was only as thick as a straw.

The hose was stuffed into Shi Quan's hand.

"There are dozens of optical fibers stuffed in it, with a maximum length of one kilometer. You can take this down with you later. Not only can it mark the route, but in an emergency, this hose can also provide you with oxygen or fresh water, and it can even be used for communication.

question."

As Haining spoke, he pulled out something similar to a POS machine from the small door, pointed to the interface on the back of the machine and said, "When emergency communication is needed, open this interface and the sealing cap at the end of the plastic tube and connect them together.

As long as two of the four innermost optical fibers contained in separate plastic tubes are not broken, text, voice, and even images can be transmitted in real time."

"This thing is good." Shi Quan held up the plastic hose and looked at it, "Are there any shortcomings?"

"Don't bend it at right angles, otherwise the optical fiber inside will be easily broken."

Haining said proudly, "But as long as the plastic hose outside is not too damaged, even if all the optical fibers inside are broken, there will still be a few spare metal wires that can transmit signals, but the speed may be slower."

Having said this, Haining operated the panel on the carriage, and the plastic tube in Shi Quan's hand suddenly flashed with lights of different colors.

"12 colors are available," Haining said with increasing pride, "We can even agree on different color signals to represent different emergencies."

"That's enough, that's enough."

Shi Quan quickly refused. This Haining was very imaginative, but it seemed that he had not considered practicality at all. This must be another "surprise" prepared by the engineering man for Gennia.

"Next time, add a radio signal amplification function," Big Ivan put forward a pertinent opinion.

"This is easy to say, I..."

"You should think about it slowly first, don't be in a hurry." Shi Quan did not dare to give him a chance to continue, "Everyone, please prepare yourselves. We will start exploring the cave in ten minutes!"

Everyone dispersed in a hurry. Those who should have weapons took weapons, and those who needed to change clothes changed clothes. Even Master Deng took off his chef hat and put a helmet on his and his wife's heads. He started the stowed dining car and was ready at any time.

Charge into battle.

At the entrance of the mine, Shi Quan, who had already put on a wet diving suit, put on his mask and mask, fixed the blue-light plastic tube on his belt with its own Velcro, and followed He Tianlei, who was leading the way, into the tunnel illuminated by the headlights.
