Half-immortal civilization

Soon, the soil settled and everyone was busy again.

"There is still an actual depth of 55 meters; but the backfilling of sand and gravel is so powerful that it is 73 meters! The overall thickness is still 128 meters!"

The new measurement data made Zhang Chen frown a little, and he seemed a little optimistic.But it doesn't matter, there are plenty of projectiles for the rail guns of the master company!

Ten kilometers back, the next thing is the solo dance of the space shuttle.

After precise calculations, large and small guide rail shells have completed the work of the excavator by controlling the bullet point, angle, power, etc.

The space shuttle is constantly launching, and the engine is constantly roaring in order to maintain balance; in space, the water vapor ejected from the engine is like a dream.On the other hand, smoke and dust rose and fell on the ground without stopping.Pieces of sand were hit by rail guns and splashed tens of hundreds of meters away.Through such cumulative effects, the excavation work without an excavator is completed!

It's just that if it is possible, the moon will definitely cry, this is a bully, isn't it!
More than ten hours later, a brand new landform appeared in front of Zhang Chen and others!

In front of it is an irregular oval crater with a diameter of more than 300 meters, and there are densely packed impact points inside; deformed or broken projectiles can even be vaguely seen in some places.Ahead, there are patches of undulating sand dunes, all of which are brand new tumbling sand and gravel; this is caused by a railgun shot.The scattered silt, etc., covered a radius of more than 3000 meters!Let the terrain here change completely!Gaoshou Company did a plastic surgery for the moon for free - but I don't know if the moon girl with a pockmarked face is willing.

On the northerly position above the cave.A lonely crater with a diameter of about 30 meters has become the lowest point of the crater with a diameter of more than 300 meters and a depth of more than 190 meters in the center.The cave below has been shaken and collapsed, but after the measurement, it was found that the error is within an acceptable range, because the remaining depth is about 20 meters and needs to be excavated by hand.But that's already pretty good.

"Thank you brother for your support, let's just do it ourselves!" Facing the space, Zhou Xu waved his hands vigorously.Although it is said that the other party is 90.00% invisible.But what—what if I saw it!cough cough.People have helped so much, so I should thank you.

"You're welcome, this time the power consumption is 1.56 million kWh, and you can help pay the bill later!" The space shuttle echoed.

"Pfft... don't be so ruthless! These days, the electricity consumption for residents has already risen to 2 yuan. In some places, the electricity consumption of factories has already risen to 5 yuan! If you want money, you will not give it!"

"Oh, it's so sad; others say that if you want money, you will die; you are an iron cock! Sad, sad!"

"...haha... our lives are very precious! We need a space shuttle that costs more than [-] billion yuan to walk!" After solving the immediate problem, everyone laughed happily.

"Okay. The next thing is to rely on ourselves." Zhang Chen was full of spirits, "Our slogan is..."

"Entertainment depends entirely on hands!"

puff……

"Get out of here, get to work!" Zhang Chen's face was full of black lines, and this active person turned out to be one of his students!Well, it's really embarrassing!

The depth is more than 20 meters. For safety, everyone must complete the transfer of at least 1000 cubic meters of earthwork. Among the 50 people, except for 10 veteran experts who don't need to do anything, the remaining 40 people are all busy.On average, each person has to complete the transfer of 25 cubic meters of earthwork.It's not an easy job, not even with the low gravity on the Moon.In particular, space suits bring too much inconvenience, and there are no special tools at hand.

A small pothole actually kept 40 people busy for four days before it was considered complete.After that, special lunar cement was poured around the cave to fix the hole.

"You're done!" Everyone applauded each other to celebrate, and then took a photo together.After just four days of work, everyone turned into little gray clay figurines, and the lunar sand that contained a lot of iron filings made it impossible for the space suit to be cleaned; it needed to be returned to the ground to complete the cleaning.

A simple steel triangular frame is erected above the straight cave, which has been reinforced by pouring cement and backfilled with aluminum plates and fiber mesh to block the sediment.

In the vacuum world, it is weird and full of alternative temptations.The steel frame was shaking violently, and there was constant friction and collision between the pulleys and the steel, but there was no sound; only the discussion sound in the headset, so that everyone would not think that this was a silent movie.

"Hey, hey, get ready, we are about to enter the moon to explore. Wow, maybe there is a mythical Chang'e waiting for us under the moon!"

"Haha, boy, you're crazy like a woman. Don't worry about Chang'e, but there are poisonous insects."

"Get out! I can't communicate with you! Chang'e represents a beautiful vision, and you are a cancer of society!"

"Okay, boys, quickly check the supplies, we are about to enter the mysterious inner world of the moon. Our names will be forever recorded in textbooks." Zhang Chen was excited, and his tone was much more relaxed and humorous.

"Teacher, I will report the list of existing supplies, please check.

There are 15 portable physical batteries, each with 2000 degrees of energy storage, and the average energy storage is 97%, which is qualified; each person has a backpack, which contains 10 liters of water, 5 kg of food, and 50 kg of compressed air.There are also two small seismic wave generators, various sound wave detection instruments, and various analytical instruments as follows... and four sets of ropes and rock climbing tools... lighting tools..."

"Oh, yes, all is well, let's go! We'll have two days to explore; but don't go too far, we'll have to return after two days anyway, and wait for the space shuttle to drop supplies."

Hearing all the reports, Zhang Chen sighed secretly. Fortunately, the gravity of the moon is low. All the weights, plus the spacesuit, each person can carry up to 150 kilograms (mass); because the gravity of the moon is low, the actual weight is only 25 kilograms (moon weight); even with some instruments, the load did not exceed 50 kg.For the pilots of the master company, it is not a big problem to carry 50 kilograms!
In fact, this is one of the reasons why Zhang Jingyuan asked Zhou Xu and others to come here. It is difficult for ordinary people to support a 50-kilogram load without training for a long time; even some people who have been doing research in the laboratory all year round may not necessarily lift You have to move your legs!
——————— Hateful dividing line———————

It is said that when a master company digs a hole here, other countries are not stable.The rail guns continuously impacted the moon, and the accumulation caused the smoke and dust to rush out of the sky at a height of more than 500 meters, and even part of the dust rushed out of the moon; it also caused the moon to vibrate continuously.Because of the emptiness inside the moon, these vibrations are appropriately amplified and prolonged.Although it is said that after more than ten kilometers, people basically cannot feel the vibration, but the instrument is different; the slightest vibration can be detected!There are detectors from various countries all over the moon; I dare not say more, there are still thirty or fifty.Every country wants to get a share of the moon, especially countries with small land and good technology like Switzerland and Japan.

It's just that these countries really can't sleep in the face of such crazy moves by master companies!There is such a neighbor on the earth, it is really not worrying.

Sighs came out from the mouths of these leaders, but in the face of reality, there was nothing they could do!If you have more than enough heart but not enough strength, you are talking about the present! (To be continued..)
