The next day, Lao Mai did not care about the time as in the past, and kept meditating and cultivating, but according to the normal schedule, he got up in the morning and washed up, and went to the restaurant to have breakfast.

Commissioner Dong was also there in the restaurant, and when he met Lao Mai, he only said one sentence: "Gather in the square in a while, and set off to the construction site at half past eight." ”

Lao Mai nodded and said nothing, after eating soymilk fritters, Shi Shiran walked back to his room, turned on the TV, watched the morning news, and at 8:15, he closed the door and went out.

When I went to the central square of the underground base, I saw that there was already a modified open-top field tool truck parked on the side of the road in the square, and Commissioner Dong, wearing a colonel's uniform, was standing next to the car waiting for Lao Mai, holding two yellow engineering hats in his hands.

In addition to a driver in camouflage uniform, there were only Commissioner Dong and Lao Mai, who got into the car together, and the car drove along the secret door deep in the underground base into the underground river passage.

As the car drove all the way, it could be seen that the area had been in operation for a long time, and the underground river had long been converted into a sewer, and above it was a two-way two-lane cement asphalt pavement, and half an hour later, the tool truck drove to a large construction site.

It is a huge cave, with a horizontal diameter of far more than 100 meters and a height of nearly 100 meters, with a large waterhole in the middle, which is brightly lit on the right, and excavators roar to dump the excavated mud and rocks into the waterhole.

On the edge of the cave wall around, there are many small excavators digging or trimming uneven soil and stones, probably preparing to build a piece of stone, bricks and wood, excavate into a cavern or reinforce into a retaining wall, in the repaired section, there are mud trucks pulling into a car of stones, bricks and wood, and a team of engineers are laying bricks and pouring mortar in the base stone.

Lao Mai visually inspected the dome and found that it was a rock layer that was formed together, and he was a little shocked in his heart, such a big cave was actually made by the erosion of water droplets and stones for a long time, and it was really a miracle for a long time.

On the right side of the cave wall, a large opening more than 100 meters wide has been opened by blasting, where the large excavators dig out the large piles of mud and rock, and fill them into the large pool.

There are four field tool carts like tractor wheels driving directly to the construction site, along a very steep dirt and stone path, climbing into the big opening.

Lao Mai got up from the car and looked at the excavation progress in the big mouth from a distance, which was already nearly 200 meters long, and it seemed that the rock and soil that should be shoveled away had been almost cleared, revealing a large layer of hard rock.

A group of engineers wearing engineering hats and camouflage uniforms immediately dispersed and used electric drills to dig cannon holes in the rocky area.

Another group of engineers in charge of blasting was preparing mines, tubes, and explosives, and when all the blast holes were opened, they stepped forward to place them, and pulled out the detonating cable to the detonation site.

Lao Mai's eyes were sharp, and he saw a safety corner near the left, and there was a detonator on the ground, which can be imagined, and the sappers will twist the cross button on the detonator, and the entire mining tunnel surface will explode again and again, the sound will shake the sky, and the mountain will shake the ground.

After a while, the car drove to a stop near the safety corner, surrounded by the roar of machinery, and several people in the car did not pay attention, and a military command car followed them.

"Colonel Dong, Colonel Dong!"

This voice shouted several times in a row, and then Commissioner Dong looked back when he heard the voice, quickly stood up, opened the car door and jumped to the ground, and the command car behind also stopped, and a male officer in his forties, wearing a camouflage uniform and hanging two cents and three epaulettes, pushed the car door and stepped out.

Lao Mai was still standing in the car, quietly watching them salute and shake hands with each other, and only then did Commissioner Dong turn around and wave to him, then he slowly stepped out of the car door and walked over slowly.

Commissioner Dong introduced them to them, saying that this was the specific person in charge of the excavation site and the head of a certain engineering unit, and asked them to suspend the blasting first and show Lao Mai the rock formation.

Captain Pang had a dark round face, but he shook hands with Lao Mai very warmly, expressing a warm welcome, obviously he already knew that during the excavation of the UFO passage this time, he needed to use the help of precious powers.

The width of the passage is 120 meters, the dome is 45 meters high, the wall is 35 meters high, the inclination is 15 degrees, the length is 2.6 kilometers, and it extends from the edge of the waterhole to the ground.

The higher commander demanded that the engineering unit complete the excavation and construction of the passage within two days, because two days later, the flying saucer towed from the place of the fall, towed by dozens of large tractors, was about to reach the entrance at one end of the ground.

Lao Mai followed them, listened to the briefing, and turned around along the face of the tunnel that was being excavated, looking silently calculating something, and then said to Commander Pang: "Commander Pang, if you believe me, leave the excavator commander and geological location surveyor, and withdraw the blasting team." ”

"Haha, how could my old Pang not believe it, Director Mai, I'll leave it to you here, I'll let people arrange to speed up the landfill of the waterhole and the reinforcement of the cave wall," Captain Pang was overjoyed when he heard this, and beckoned someone to come over to explain the work.

Lao Mai's glorious deeds of collapsing half of the big stone mountain alone have been spread throughout the mouths of the officers and soldiers of the engineering corps who are working on the site in the past few days, and everyone is amazed in unison at the strength of the means of this master of land control, as long as it is necessary, the Himalayas and Mount Everest can also be collapsed.

So, the entire demolition team withdrew, and there were still a few people who felt strange and wanted to go back to see what was going on, but they asked Commander Pang to send guards to bomb them away.

Captain Pang handed over other engineering tasks, but he stayed at the excavation site, he was very curious about how Lao Mai excavated these hard rocks, and he didn't see it with his own eyes, and his heart was not steady.

I saw Lao Mai walking alone to the excavation face of more than 100 meters, touching here and pushing there, then walked back, and said to Commissioner Dong and Head Pang, who had been staying in the safety corner: "Each time it is not more than ten meters deep, and then, I need to rest for fifteen minutes." ”

Before Captain Pang could speak, he only heard the sound of huge 10,000-year-old stubborn stones on the other side of the palm side peeling off one after another, and all the large rocks in the past cracked one after another, and in less than a while, they became piles of gravel, which could be removed with hook machines and forklifts.

Commander Pang unconsciously opened his mouth wide, and a pair of eyes on his black face were about to protrude, as the commander of the engineering corps, he had experienced many arduous projects in his life to excavate earth and stone, and the blasting project of such a large rock layer was enough for a battalion of blasting team to do a morning.

But the Earth Controller walked around so easily, and these huge boulders became rubble that could be shoveled at any time.

In this way, the project at his own end is not only several times faster than the original, the progress of this kilometer does not take two days, and it is almost completed in one day, plus the time to keep up with the reinforcement of the dome and rock wall at any time.

"Don't look at my easy walk, I'm about to lose half my life when I walk down this circle," I saw Lao Mai, who had just walked back, standing with his waist on his back, his face pale, and beads of sweat the size of beans were rising.

Commander Pang hurriedly called the commander of the excavator, instructed a large group of excavators to start shoveling soil immediately, and asked his guards to move a folding chair and sit down for Lao Mai to rest.

The young guard was very attentive, and after a short time of running out, he actually brought back four folding chairs, and it was obvious that there were many folding chairs in the temporary headquarters of the project set up by the waterhole outside.

At this moment, several leaders above the regimental level had places to sit, and Lao Mai sat down and did not participate in the comrade-in-arms dialogue between them, and closed his eyes to recuperate.

Fifteen minutes later, he opened his eyes and found that the excavator group at the construction site was still very efficient, basically emptying the face of the tunnel that had smashed the ten-meter-deep stubborn stone, so he stood up and continued to complete his task of crushing the boulder.

At the same time as the excavator group shoveled the soil, the reinforcement of the dome and the two walls was also intensified, except for a part of the engineers who were left outside to build the surrounding rock walls and continue to strengthen the retaining wall, the rest of the engineering construction personnel came in in groups in turn to participate in the newly opened cave wall reinforcement work.

Fifteen minutes to excavate ten meters, one hundred and fifty minutes, that is, two and a half hours, can excavate 100 meters, if you do not eat, drink, sleep or sleep, you can complete the excavation progress of one kilometer in 24 hours a day.

The original blasting team here has withdrawn to the mouth of the passage at the other end, strengthening the blasting force on that side, so that the progress of the excavation at that end has been accelerated, it seems that in less than two days, the two sides can open up the entire passage, and the division will be successfully carried out, and the only task left is to reinforce and repair and widen the passage.

Lao Mai has no problem fighting continuously for a day and night, with that fifteen-minute rest time every trip as cover, and it is also possible to do it casually without sleeping, just as it is a secret cultivation, and it can also absorb a little earth aura as compensation.

Commander Pang, who was commanding with red eyes, seemed to be used to staying up for time, and when he sat down to rest for a while, he stood up to command this and that, and he was also busy from time to time.

In fact, the hardest thing is to sit on the side and accompany Lao Mai with nothing to do Commissioner Dong, he is neither an armed soldier nor a cultivator, just a natural spiritual eye ability, so staying up for such a time is really hard for him, and he has to unconsciously or unconsciously exert the spiritual eye function, boring to detect how many meters Lao Mai can penetrate every time.

After more than a day of excavation, the two ends of the 2.6-kilometer passage are about to be dug through, and the two engineering units and a regimental-level team will immediately join the division.

Just when the two sides were about to dig through and take it lightly, a small accident suddenly happened, that is, when the outer excavation party excavated and placed the last blast hole, the number and dose were increased, and the blasting equivalent was much larger than before.
