Several steam trains spewed thick black smoke, once again loaded with various supplies and gun clones, carrying a large amount of bullets and leaving the main base. At this moment, all the strange birds around the main base have been cleared out. At most, a few solitary strange birds occasionally gather here and can be easily killed. But as they moved some distance away from the main base, the number of strange birds gradually increased and the battle broke out again. Then, the windows of the steam train were opened, and more than a dozen guns appeared in one carriage, firing fiercely into the distance. Not only that, some clones climbed to the top of the train and fired at people from above. Some clones did not take the train, but ran along the sides of the train. This made their combat more flexible, not only giving them a wider shooting field, but also making it easier to move positions. So under the attack of this trinity, as many strange birds gathered around the train as possible were killed. After killing the strange bird, the armed clones threw their guns into the carriage, picked up wrenches, hammers, rails and other materials, and began to repair the damaged railway. The transition from soldier to engineer was extremely smooth and natural, without any lag. The train continued to roar forward and finally arrived at the No. 1 Copper Mine.
As a bridgehead, the No. 1 Copper Mine has always been hit the hardest and suffered the heaviest casualties. But it doesn’t matter, at this moment, the gun clones are here, and victory is here! Hundreds of clones jumped down like wolves and tigers, picked up their guns and fired a volley of shots. In more than 20 seconds, more than 30,000 bullets were fired! Li Qingsong's concept in designing this firearm, which he named "Assault Type 1", was not to pursue accuracy but only rate of fire, and then to defeat the enemy by relying on numbers with an almost endless supply of bullets. It is not easy to improve accuracy. The accuracy of gun processing must be improved little by little. High-precision machine tools and high-performance materials are required. Why go to all this trouble? I might as well make tens of thousands of bullets. Tens of thousands, hundreds of thousands of bullets can be fired at once. What enemy can't be killed? As a result, a large number of strange birds that besieged the No. 1 Copper Mine were killed in an instant. The cold weapon clones who had just been fighting desperately breathed a sigh of relief and retreated immediately, leaving the front line to their companions who came to support them. The situation that happened at the main base happened again. Under the endless onslaught of bullets, the strange birds fell down in large numbers and were eventually killed. At the same time, the clones that took the other trains to the other mineral bases also achieved similar effects. Not only that, there is still a steady supply of guns and bullets being produced at the main base. So, in just less than five days, all the strange birds that besieged their bases and railway lines were wiped out. There is no strange bird within a radius of ten kilometers! At this moment, Li Qingsong finally felt relieved. "But it's not time to really relax yet." Li Qingsong thought secretly: "Luoshen Star is too big, and my base group occupies such a small area. I don't know how many strange birds there are in the distance. I have to conduct large-scale reconnaissance to confirm their movements and numbers. At the same time, the development of weapons technology can no longer be ignored in the future. On this tiny planet of Luoshen, there are such strange creatures. Who knows how many dangers are hidden in other places."
After making the decision, Li Qingsong immediately recalled a large number of clones to the main base. With enough guns and bullets, Li Qingsong only left 400 clones to defend each base in the outer mineral bases. Although the number has been greatly reduced, the overall combat effectiveness is still several times greater than the previous 2,000 cold weapon clones. Even the main base only needed 1,000 clones to defend it. But in order to ensure that nothing could go wrong, Li Qingsong still dispatched 2,000 clones to patrol day and night. Adding the total of 1,000 clones needed for the railway line, the total number of clones Li Qingsong deployed in defense has been reduced from the original 16,000 to only 7,000 at the moment. The remaining 9,000 consciousness connection shares can finally be withdrawn. It just so happened that the clones in the main base who were responsible for basic production tasks had been exhausted over the past period of time. It was a good time to send more people over to let them have a rest. So Li Qingsong started a new round of large-scale clone mobilization. In addition to the 7,000 clones responsible for defense missions, Li Qingsong also specially selected 1,000 clones to perform reconnaissance missions. They divided into a team, each driving an off-road vehicle, and went further to search the desolate and silent land of Luoshen Star. Of the remaining 8,000 consciousness connection shares, a portion was added to basic production, and with the other portion, Li Qingsong started another more important task. Research and development of weapons and combat equipment! At this stage, there is only one assault type, and the combat mode is too weak. More combat equipment is needed. "The environment on Luoshen is different from that on Earth. I can't build a flying vehicle here for the time being. Then we can only think of a way to build some combat weapons like armored vehicles and tanks. This thing is relatively simple, just pile up armor. But... the power problem is difficult to solve, my battery technology is not good enough. " After thinking about it, Li Qingsong decided to use an internal combustion engine as power. There is no gasoline on Roselle, but there is still a lot of methane. Methane has a lower density than gasoline, but a higher calorific value, so on average, it is about the same. Gasoline can be burned to power a vehicle, and so can methane. In particular, the gravity of Roselle is low, so the "fuel consumption" is naturally low. In the past, the technological level was not high enough to produce internal combustion engines, but of course it is different now. The only difference from Earth is that vehicles on Earth do not need to carry oxygen because there is oxygen in the atmosphere. The internal combustion engines on Luoshen have to carry oxygen. Taking into account various factors, including differences in gravity, terrain, fuel, technology, etc., Li Qingsong estimates that he can use an average of 8 liters of methane and oxygen to drive a three-ton vehicle for about 100 kilometers. "Eight liters per 100 kilometers, that's enough." Having made up their minds, larger-scale scientific research began immediately. Li Qingsong not only has to make more guns, but also armored vehicles, tanks, and various artillery! While carrying out many tasks such as weapons research and development, basic production, patrol and surveillance, reconnaissance and search, Li Qingsong also brought back some strange bird corpses, intending to examine and analyze them in the biological laboratory. Li Qingsong now has a certain foundation in biotechnology. After some inspection, Li Qingsong discovered something that shocked him.
"The body fluids of this strange bird are so nutritious?!"
