Before the end of the world. Xu Zhengyang once completed a [Smokeless Powder] task, which was to ask Xu Zhengyang to collect 30 tons of cotton, nitric acid and sulfuric acid respectively. At that time, the blood plague had not yet broken out, the society had not yet collapsed, and the rule of law was still sound. So the best supplies to get at that time were high-quality cotton, just spend money. But sulfuric acid and sulfuric acid are both controlled substances, and Xu Zhengyang could only go to Siam to buy these two things secretly. But after the end of the world came, it happened the opposite. Due to the arrival of blood plague, factories around the world have now been shut down. Xu Zhengyang can get enough nitric acid and sulfuric acid whenever he goes to. Even equipment for producing nitric acid and sulfuric acid. Xu Zhengyang could also demolish his shelter and build production workshops for sulfuric acid and nitric acid in the shelter. On the contrary, the cotton that was most easily obtained before the end of the world made Xu Zhengyang difficult now...
Even the cotton variety with the shortest growth cycle takes 110 days to fully mature. Moreover, the yield of cotton is very low, and only one mu can produce about 120 kilograms. Such a low yield. If Xu Zhengyang separates the cotton growth area in the agricultural area of the shelter, there will be too much space to waste! It's at this moment. Xu Zhengyang suddenly thought of something, and immediately said to Dabai, "Dabai, get the satellite perspective of the Xinjiang Cotton Production Park!" "Okay master." Dabai agreed and synchronized the satellite's real-time shooting images to Xu Zhengyang's contact lenses. "really!" Xu Zhengyang was overjoyed after seeing the real-time shooting of the satellite! Xinjiang province has a large area and a sparse population. So there is the place that is least affected by the blood virus. In addition, Xinjiang Province is far away from the coast and has not been attacked by bloody monsters in the sea. Multiple factors add up. Xinjiang Province has become one of the few pure lands on earth! Cotton cannot be eaten. Therefore, the huge cotton production park in Xinjiang Province has begun to grow weeds because it is unattended. Looking at the huge cotton industrial park in the satellite real-time shooting scene, Xu Zhengyang was very excited! Then Xu Zhengyang immediately came to his computer.
Based on the knowledge you have learned in the engineering knowledge card before, design various agricultural machinery for growing and picking cotton! ... moment. Xu Zhengyang handed over several design drawings he had made to Dabai and said to him, "Dabai, divide some of the production capacity to make these agricultural machinery for planting and picking cotton. Then I sent me the addresses of the newly built nitric acid factories and sulfuric acid factories in recent years, and I went to bring the equipment back! ” "Okay master." Dabai agreed, and then projected a map on Xu Zhengyang's contact lenses and marked the navigation route. ... With the speed of the shuttle, plus Xu Zhengyang’s current mechanical army. It took him only half a day to bring back the various equipment needed to build the nitric acid production workshop and the sulfuric acid production workshop and a large number of raw materials to the shelter and temporarily store it. Just wait for Dabai to build the production workshop and start production directly! The relatively troublesome thing is the cotton industry park. Although Xu Zhengyang has restored the production of the cotton industry park through the new robot he designed. Two mixed combat teams were also sent to protect the cotton industry park from zombies and people with bad intentions. However, the power system in Xinjiang Province has long been paralyzed. Therefore, Xu Zhengyang had to travel to and from Xinjiang Province every day to charge his various robots, so as not to turn into a pile of scrap iron due to energy problems... ... Although it is a bit troublesome. Fortunately, the raw material supply problem of smokeless gunpowder was successfully solved, and as long as Xu Zhengyang solved ten more special ammunitions. He can successfully complete this task and get the [Super Time and Space Teleportation Platform] reward, which seems not simple! Fortunately, the materials and processes for making warheads are slightly different, and most of the base fires are universal. Therefore, as long as Xu Zhengyang solves the problem of raw materials supply for the warhead, he can successfully complete this task! So Xu Zhengyang asked Dabai, "What other materials are needed to make ten special ammunitions?" "Master, what ten special ammunitions do you want to produce in the shelter?" Dabai said. A series of text messages were projected on Xu Zhengyang's contact lenses, which were the types of special ammunitions that could be made from various raw materials: [White phosphorus: can make white phosphorus bombs, smoke bombs, and flares] [Tungsten: Armor-piercing bomb, Armor-piercing bomb]
No mistakes, one song, one content, one in 6, one book, one bar, one reading! ... There are many things. Dabai listed a total of more than ten lines of written materials for Xu Zhengyang. After the end of the world. These raw materials are not difficult to make. As long as Xu Zhengyang is willing, he can set up a large number of refuges to return to his own sanctuary at any time. That is, if Xu Zhengyang wants to stabilize the supply of materials for his refuge. This requires Xu Zhengyang to fly around the world with his dimensional space bag every day with a shuttle... "Forget it, just fly." But Xu Zhengyang had no better way now, so he said to Dabai, "Look at where there is a white phosphorus factory first, I'll get some white phosphorus back first!" ... In the next half day. Xu Zhengyang traveled around the country again and finally got enough materials needed to produce various special ammunition. When his ammunition production workshop was running at full speed, the daily ammunition speed had exceeded 10,000 rounds. A series of system subtitles finally appeared in front of Xu Zhengyang's eyes: [Main mission: Ammunition reserve (completed)] [Reward: Super-time and space teleportation platform] ... 【Space-time transmission platform】 【Skill】 (Space-Space-Space-Space-Space-Space-Space-Space-Space-Space-Space-Space-Space-Space-Space-Space-Space-Space-Space-Space-Space-Space-Space-Space-Space-Space-Space-Space-Space-Space-Space-Space-Space-Space-Space-Space-Space-Space-Space-Space-Space-Space-Space-Space-Space-Space-Space-Space-Space-Space-Space-Space-Space-Space-Space-Space-Space-Space-Space-Space-Space-Space-Space-Spa [Note: 360*10*120 meters of three-dimensional space is required to place the super-time and space transmission platform] After seeing the detailed attributes of the super-time and space teleportation platform, Xu Zhengyang was overjoyed! There is this thing here. Xu Zhengyang only needs to place it on the surface of the shelter. It is very convenient to collect resources yourself in the future! So Xu Zhengyang did not hesitate. Immediately let Dabai clear out enough space on the surface of the shelter, and then place the super-time and space teleportation platform there! This is a giant door frame full of sci-fi feel!
After the prism tower provides it with sufficient energy, the operation end of the super-time and space transmission platform is like the magic door in Hal's mobile castle, and a series of binding coordinates appear. Just Xu Zhengyang click the button. The hyper-time and space transmission platform can connect to those bound coordinates at any time, allowing the shelter and the bound coordinates to realize hyper-time and space transmission! The teleportation distance of the super-time and space transmission platform is not only six times farther than the portal obtained by Xu Zhengyang before, reaching an astonishing 3,000 kilometers!
