The formula of this aerogel was found by Jiao Bai from the two quantum computers that store scientific papers and patent documents, and has the advantages of high temperature resistance, high pressure resistance, corrosion resistance, simple production, low cost, etc., and the effect of wind prevention and sand fixation is very good. In this way, regardless of the cost, a road composed of aerogel is formed, and the vehicles that transport building materials and personnel can follow this road to the future space city.

After two days of hard travel in the desert, the convoy entered the depths of the desert, Jiao Bai drove an off-road vehicle, walking at the front of the team, Prince Alfaruk sitting in the passenger seat was fiddling with a satellite locator, and the palm-sized screen showed a satellite map and three constantly changing numbers, which were the longitude, latitude, and altitude.

Alfaruk had been holding a paper document, constantly comparing the data on the file with the numbers on the satellite locator, and at one point, he suddenly shouted "Jiao Bai, we are going to be there"

Hearing this, Jiao Bai lowered the speed of the car, turned on the walkie-talkie, and said, "I'm Jiao Bai, the convoy is about to arrive at the predetermined location, please slow down." ”

The off-road vehicle climbed a sand dune, and suddenly a red flag fluttered high in front of it, and under the red flag, there were several simple houses made of colored steel plates. Jiao Bai let out a breath, wiped the beads of sweat on his head with his free hand, and said, "It's finally here, Prince El, have you seen those houses, that's the team I sent over to fight the front station two days ago." Let's go, go over and blow the air conditioner first, this ghost weather can heat people to death. ”

The convoy continued on its way, and soon reached the house, where it parked its cars in turn. Jiao Bai picked up the walkie-talkie and ordered, "Sprinkler truck, first drench the desert within a radius of a few kilometers and fix all the sand dunes." Others hurried up to build temporary houses, and acted quickly at night if they wanted to avoid freezing, don't look at the hot weather now, it is only three or four hours before the dark sky, and time waits for no one, and they all take action. ”

More than 1,000 workers got out of the car one after another, found their captain according to the team, and then a team of dozens of people followed a transport truck to the location where the house was built, unloading the truck, and mixing cement with cement. It didn't take long for the color steel houses to be built, in rows, in rows, neatly, and neatly, finally making the desert full of yellow sand a touch of different color.

Jiao Bai entered the house built by the advance team and blew the air conditioner for a while, and drank two bottles of cold mineral water before he cooled down. As for Al Faruk, he moved a chair at this time, sat in front of the air conditioning vent and didn't move, and kept muttering some local dialects in his mouth, Jiao Bai didn't have much contact with the locals, so he couldn't understand what he was saying.

Jiao Bai took out two bottles of mineral water from the refrigerator, threw one bottle to Al Farouk, walked out of the house with another bottle, found Zhou Zhiqiang, who was holding a drawing and was checking the terrain, handed him the mineral water, and said, "Zhou Gong, drink a bottle of chilled mineral water to cool down first." ”

Zhou Zhiqiang put away the drawings, took the mineral water, twisted the cap, raised his head and poured a big mouthful, and then said, "Thank you Mr. Jiao, on such a hot day, you really can't live without water." Later, when the house is built, we will see if we can dig out the groundwater here. ”

Jiao Bai glanced around at the long yellow sand around him, and asked with some doubts, "It's all deep in the Sahara, and you can still find groundwater."

Zhou Zhiqiang pointed in one direction and said, "Who said that there is no groundwater in the desert, but most of it is buried deep." Do you see the cactus over there, since the cactus can live well here, there must be a water source underground. If you can really dig a deep well here, it will solve a big problem, not only to provide everyone with domestic water, but also to solve the problem of construction water. This is much better than transporting fresh water from outside the desert and speeds up construction. If the water quality is good enough, even the drinking water problem can be solved. ”

Jiao Bai looked at Zhou Zhiqiang's fingers, and sure enough, he saw a very lush cactus. Jiao Bai pretended to be curious and walked hundreds of meters to a few tall cacti. With the cactus shielding, Jiao Bai quickly summoned a pangolin, and then ordered it to activate the Earth Escape skill to explore the past below the ground.

With the help of perception and sharing ability, Jiao Bai "sees" the situation below the ground. Unlike the dry sand and gravel on the ground, the soil here is slightly sticky, and the cactus' well-developed root system is scattered in between, and it is dense and straight down. The pangolin also continued downward, going deeper and deeper, and after more than 20 meters, the humidity began to gradually increase, and the cactus' root system became more and more sparse. After the depth exceeded forty meters, there was no more sand and dirt, and twenty was replaced by a layer of hard rock, and the huge stones were tightly stacked together, only in some stone crevices, there were small streams of water coming out.

If it is a mechanical drill bit, it can only be hard steel when it hits these stones, and it can be slowly grinded through, but the pangolin has a fossil as a mud skill, and a few skills fall down, and a dirt channel is formed. Thirty meters down again, the pangolin, which was walking through the thin mud, suddenly felt light under his body, and then fell into the water with a "poof", and was directly rushed forward by the turbulent water for hundreds of meters, and then broke free.

"Hey, I didn't think that under the world's largest desert, there is an underground river with such a large flow. Now it's okay, and you don't have to worry about water. ”

Jiao Bai opened his eyes, muttered a few words to himself, and then pretended that nothing had happened, and returned to Zhou Zhiqiang's side. As for the pangolin, Jiao Bai did not return either, but ordered him to return to the rock layer to stand by. Jiao Bai's plan is to wait until a while when the well is drilled, let the pangolin do a favor and put a few fossils underneath as a mud skill, so that the drill bit can be drilled to the location of the underground river one step earlier without the rock obstruction.

In just ten minutes, Zhou Zhiqiang had already set up a surveying and mapping instrument in the same place, and while reading the data above, he was very busy writing and painting on the construction drawings. Jiao Bai stepped forward, glanced at the drawings and the numbers marked by Zhou Zhiqiang, and shook his head regretfully. The so-called interlaced lines are like mountains, and the well-organized drawings in Zhou Zhiqiang's eyes are just some messy lines and piles of meaningless numbers in Jiao Bai's view, which is not clear at all.

"Zhou Gong, the planning drawings and construction drawings of these aerospace bases are not bad, are there any unreasonable or areas that need to be improved, if there is anything to tell me as soon as possible, I can contact the design institute to revise it." ，，，
