During the uninterrupted learning, Li Qingsong controlled the clone and used those metal processing equipment to process a set of simple glass production equipment. This set of equipment cannot be used in a vacuum environment, but must have sufficient atmospheric pressure. For this reason, Li Qingsong had to find another small cave and seal its entrance with a film to create an environment suitable for the operation of this set of equipment. It is mainly composed of the following parts: first is the raw material processing tank. There is also a lot of silicon dioxide on Luoshen, and its purity is not low, so it can be used directly. So in the raw material processing tank, these silicon dioxides are mixed with some sodium oxide, limestone, etc. They are then sent to a furnace where they are heated to over 1,500 degrees Celsius by electrical heating, at which point they are completely melted. After that, the clone in charge of blowing will use a long blowpipe, dip a little glass solution, and blow it towards the mold, and a glass tube will be formed. Wait until it cools down and then you can use it. At this moment, Li Qingsong was of course using an extremely simplified manufacturing method. The glass tubes made in this way had a lot of disadvantages, such as low transparency, many burrs, and easy to break. But all the disadvantages are not as good as one biggest advantage. The fact that it can be produced at this stage is its biggest advantage!
In addition to the 17 clones who were responsible for agricultural production and stayed behind, Li Qingsong specially assigned two clones among the remaining 10 clones to blow glass tubes. Of the remaining eight, two drove planetary rovers and began searching for mercury and argon based on previous exploration guidance. These two elements are indispensable in fluorescent lamps. Of the remaining six clones, three stayed on the surface of Rosene, operating blast furnaces and metal processing equipment to produce tungsten filaments, metal sheets, etc. needed for fluorescent lamps. The last three brought these products back to the Deep Space spacecraft and used the spacecraft laboratory to begin manually making equipment such as starters. All 27 bodies started working again, with no one idle. When the colorless argon ore and silvery-white solid mercury, which had also been frozen solid, were found and brought back by the clones, the first batch of glass tubes, starters, ballasts, etc. had also been made. Li Qingsong manipulated a clone to begin the final assembly work. For this primary technical stage, the most difficult step should be vacuuming. After all, the interior of the fluorescent tube needs to be evacuated first and then filled with argon gas. But this step is not a problem at all for Li Qingsong. The reason is very simple. The surface of Luoshen is vacuum everywhere, so there is no need to pump it. Then, some tiny devices and circuits were filled into the glass tube. After making a fluorescent lamp, Li Qingsong carefully connected it to the power source. The next moment, a bright light was released from the lamp tube, and the swaying clone couldn't help but narrow his eyes. “Not bad, not bad.” Li Qingsong was very satisfied with this. By verifying the ability to manufacture fluorescent lamps, the biggest obstacle to building the second planting base was eliminated. So, among these 10 clones, five were responsible for making fluorescent lamps, and the other five operated various equipment and began to manufacture planting racks. The appearance of this planting rack is similar to a bookshelf, but it is transparent on both sides.
A planting rack is about one meter wide, two meters high, and three to four meters wide. It is divided into two to four layers according to different needs. If it is divided into two layers, some crops with taller plants, such as wheat and rapeseed, can be planted. If it is divided into four layers, only crops with shorter plants, such as wheat and sweet potatoes, can be planted. There are also unlayered ones, which are used to grow corn. Li Qingsong made various kinds of planting racks. This time, the construction of the planting base is not as simple as just planting a few crops. Li Qingsong plans to plant everything that is useful. Even if they cannot be eaten, they can be used for industrial purposes. Time passed slowly, and in the blink of an eye, several months had passed. Li Qingsong added another 5 clones under his command, bringing the total number to 32. With the only tractor working for more than ten hours a day to transport fuel and ore, with 32 clones busy all day, with the blast furnace smelting all day, and the metal processing equipment roaring all day, all the equipment needed for the No. 2 planting base was finally manufactured. Even the larger generator prepared for Base No. 2 has been built. Finally it was time for the actual construction. The 15 clones came to this huge cave, which had been explored in the early stage and had a total internal area of 11,000 square meters, in a heroic and confident manner, wearing tattered and low-quality space suits covered with tape. Such a huge cave without any support in the middle could probably only be formed on the planet Luoshen, where the gravity is extremely low. If it were on Earth, it would have collapsed long ago. Although this cave is huge, the exit is not big, only about ten square meters in total. The 15 clones worked together to move the materials, and then used the specially produced steel plate as a door to seal the hole. At the same time, they left an entrance and an isolation cabin under the door to facilitate the clones to enter and exit. The inside of the cave is sealed by rock, and the entrance is sealed by an iron door, thus isolating the inside from the outside. The 15 clones worked together again, and the long metal hoses served as floor heating pipes. It only took a few hours to fill the entire cave. As the steam generator roared, the heat was transmitted to the pipes and began to heat the surface. A large amount of frozen material began to vaporize directly and then rise into the air. Under normal circumstances, they should naturally flow to places with low air pressure. But now the exit is blocked by the iron door, so they can only accumulate inside the cave. With a certain temperature, they begin to melt the frozen materials on the rock walls and the top of the cave into gas, so the pressure inside the cave becomes higher and higher. When the pressure rose to the equivalent of one atmosphere, a clone opened the gas outlet. Then all these miscellaneous gases rolled out and surged out like a long sword. After gushing out for several meters, it cooled down and turned into snowflakes falling down. Once the internal pressure drops, the vent is closed and the interior begins to heat up again. This was repeated several times until all the messy gases inside were finally emptied. At this point, Li Qingsong controlled the clones to put relatively pure solid oxygen, solid nitrogen, a certain proportion of carbon dioxide and other gases, as well as water ice, into the cave. After they all melted and turned into gas that filled the entire cave, Li Qingsong controlled a clone to enter Base No. 2. Taking off his space suit, breathing the slightly moist air, and looking at the huge, empty cave, Li Qingsong murmured in his heart, "What a great place."
