Ye Han jumped to the designated position, picked up a boulder with a diameter of no less than one meter under his feet, and easily lifted it above his head and threw it out of the pit. Pen % fun % Pavilion www.biquge.info

The boulder thrown out of the pit is like a slow motion in a movie, flying to the highest point and falling slowly, smashing on the hillside and jumping lightly, slowly rolling along the slope of the mountain to the foot of the mountain, everything is so slow.

However, Ye Han's movements were not slow at all, large and small stones were thrown out of the pit one after another, and the appropriately shaped drips rolled down the mountain, and the edges and corners were piled directly on the hillside, and after a while, a stone pile more than three meters high appeared outside the pit.

The low gravity of the moon and the strength bonus of the 2.0 version of the armor made it difficult to lift stones with a mass of less than five tons, and all the equipment of the two bases on the moon was combined, and there was no equipment more suitable for cleaning the pit.

Higher-quality stones can also be lifted, but in that case, it is possible to damage the armor due to overload, so Ye Han will not do this kind of deed.

There are too many rocks in the pit, and the stones outside the pit are three meters, but the inside of the pit is only about one meter down.

Ye Han couldn't help but ask: "Old Gao, how many meters above sea level is the tunnel design?" ”

"Fourteen meters!"

Ye Han sent a positioning request to the satellite, which determined that the altitude at which he was located was 17 meters above sea level, which means that if he dug down three meters, he should find the TBM.

That's great news!

In the past, a crater near the central bay on the front side of the moon was strongly set to an altitude of 7,000 meters above sea level, which served as the moon's sea level benchmark.

It is easy and convenient to follow the standards of Westerners, but the Northern Capital clearly does not intend to do so, and after the start of the Moon Palace project, the surface of the glacial lake in Pit No. 1 was directly set as the sea level benchmark, and all the height data of the Chinese side followed this standard.

"Can you get in touch with the TBM?" Ye Han asked again.

"Yes, how?"

"Turn the com, I'm going to talk to him." Ye Han said.

"Okay." Gao Kai agreed, and soon connected the two people through satellites.

"Brother, how do you feel?" Ye Han said hello.

"Okay." After a period of precipitation, the trapped driver has calmed down.

Ye Han stomped his feet twice: "Can you hear me?" ”

"Hear what?"

"The sound of stomping." Ye Han said, "I'm right on top of you, now I'm stomping, you tell me which direction the voice is!" ”

The power armor has a limited endurance and cannot afford to waste limited power, and determining the exact position of the TBM can save the most energy.

"Oh...... Good! ”

Ye Han continued to stomp his feet, and heard the voice of the trapped driver in his ears: "In front of me on the right." ”

Ye Han took two steps and continued to stomp his feet.

"Left!"

Ye Han moved back a little more.

"Up!"

Finally found the right position, Ye Han immediately took action, moved and pushed, and went all out to dig down, ten minutes later, Ye Han pushed away a boulder more than one person high, and finally found a twisted steel frame under the boulder, as well as a laser drill bit installed at the front end of the steel frame.

He immediately cleared the rubble near the steel frame, revealing the mottled shell of the TBM.

Ye Han knocked on the heavy armor vigorously: "Can you hear me?" ”

"I hear you, very clearly!" The trapped driver said excitedly.

"Old Gao, I've dug into the TBM."

The radio waves sent Ye Han's voice into Gao Kai's ears, and Gao Kai immediately breathed a sigh of relief: "Hurry up and save people." ”

"No problem." Ye Han said, "In which direction is the door?" ”

The TBM is armored to prevent collapses, and of course it does not make a hole in the roof like a normal tank.

"Left!" Gao Kai said.

Ye Han looked to the left and couldn't help grinning. The outside of the TBM was crowded with rocks of all sizes, and it was not so easy to dig out the door.

"What am I digging for, I!" Ye Han stood on the roadheader and sighed, "Just such a few stones, the excavation team will be transported in less than half an hour, can you toss me?" ”

Gao Kai was stunned: "Are you sure?" ”

"There's a TBM under my feet, you say?" Ye Han said.

The tunnel has been dug to the edge of the crater, and with a little more effort, it can be completely penetrated, and above the collapsed section is not an untold amount of basalt, but a weathered rock less than ten meters thick!

As long as the stones blocked at the end of the tunnel are removed, it is equivalent to penetrating the entire tunnel, why should he Ye Han be as tired as a dog to throw stones?

Gao Kai forwarded the news to the excavation team, and the team leader slapped his thigh and immediately ordered the whole team to dig soil and rocks.

A mechanical boring machine drives into the tunnel, and a wildly spinning drill bit crushes the rocks that are clogging the tunnel.

At this time, if you continue to use the laser boring machine, you may injure the trapped people if you are not careful.

During the initial creation of the base, the temporary base lacked personnel and equipment, but there was no shortage of electricity, so the equipment distributed at that time was mainly electric drive.

The advantages of electric drive equipment are outstanding, but there are also many disadvantages, such as laser tunneling equipment can not be accurately controlled, often a high-energy laser can cut into the rock layer several meters or even more than ten meters deep, so the excess gaps must be sealed in the later stage of the project to avoid pressure loss accidents.

At present, the smelting group has been put in place, and the base has the basic conditions for using traditional equipment, and the equipment that should be replaced must be replaced.

A large amount of rubble was sent out of the tunnel through the conveyor belt, and in a short time, a section of the tunnel seven or eight meters long was cleared, and you could see the bright starry sky when you looked up.

Ye Han outside first saw that the stones in the depths of the pit began to vibrate, and then the stones quickly sank, and after a while, the huge alloy drill bit pierced the rock formation.

As the TBM continued to advance, more and more gravel was carried away by the conveyor belt, and Ye Han simply jumped out of the pit, avoiding the TBM and jumping into the tunnel that had just been cleared.

It's back to base, and there's no need to fly back at all.

The excavation team was taken aback by Ye Han who fell from the sky, Ye Han identified himself and told the situation outside again.

After getting the first-hand information, the excavation team leader was overjoyed and immediately informed Gao Kai: The tunnel is about to be broken through!

Gao Kai had already learned about the situation outside from Ye Han and had already realized that the tunnel breakthrough was just around the corner, but he did not rush to report, but patiently waited for the confirmation of the tunneling team before informing the ground of the news of the tunnel breakthrough.

When the ground command center received the news, it was jubilant.

The country is doing its best to support the construction of the lunar base, and resisting aliens is only one aspect, and another important reason is to take the lead in controlling the lunar resources.

Although the crater provides a relatively stable environment for the Moon Palace base, the towering peaks also limit the development of the base, and the Shanbei Tunnel is like pushing open a door and opening a window, showing a broader world in front of everyone, and the Moon Palace base no longer has to be limited to the No. 1 pit, creating conditions for further utilization of lunar resources.

This is of extraordinary strategic significance to the Moon Palace Base and to the entire country.
