Every inch of land in the space station is valuable, so the air circulation system is the best choice for them. But Xu Zhengyang’s shelter is not a space station. What he lacks the most here is space! So Xu Zhengyang, who walked out of the horns, immediately rushed out of the shelter and drove to the Baicheng Flower and Bird Market! * Two hours later. Xu Zhengyang's car was driving in the front, and behind it was a small truck full of trucks. After the masters unloaded the goods, Xu Zhengyang sent them away. Then Xu Zhengyang used the dimensional space bag to move the green ivy and plant lamps removed by the masters into his sanctuary in batches. Green ivy is a very easy-to-food plant.
As long as the temperature is appropriate and there is no shortage of water, and the sun is sunny for a while every day, the green ivy can grow from a small pot to a large pot at will! And even if you accidentally raise it to death. Just pick a piece of green ivy vine and insert it into the flower pot, and it won’t take long to grow a large pot again. It’s so tenacious and terrible! * Inside the shelter. Xu Zhengyang first asked the engineering robot to build a metal shelf in the living room using the scraps left from the previous work. Then put the green ivy together and install a plant lamp above the green ivy. Wait until all this is done. Xu Zhengyang turned on the plant lamp and used the handheld pump-sucking oxygen O2 gas alarm he just bought to test the concentration of oxygen nearby. As time goes by. really! The oxygen concentration around the green ivy rack began to gradually increase! Xu Zhengyang was very excited when he saw this. Then immediately manipulate the engineering robot to pour concrete into the previously reserved vents! The engineering robot is busy, and Xu Zhengyang is not idle here either. Having a shelf that produces oxygen is not enough. Xu Zhengyang also needs to monitor the content of air components in the shelter at all times to adjust the brightness control of the plant lamps to ensure the air safety of the shelter. This time. Xu Zhengyang received the reward for doing the [Decoration] task before, the shelter control center can finally use its purpose!
First, use the installed fresh air system to ensure air circulation in the shelter; The air component sensor is then arranged at various locations in the shelter; Finally, all data are combined to allocate power to the plant lamp to ensure that the oxygen concentration in the shelter can always be maintained at 20%. After Xu Zhengyang set up air circulation in the control center. His engineering robot also blocked all reserved air circulation ports in the shelter. It's at this moment. The biological air circulation system built by Xu Zhengyang in his shelter finally began to operate normally! And he finally completed this difficult limited-time challenge mission! [Limited time challenge task: airtight transformation (completed)] [Warning: Please find a space not less than 5 meters * 5 meters * 8 meters to receive your mission rewards! 】 As the task prompt appeared, Xu Zhengyang was very excited! With the GX-2 large engineering robot here, Xu Zhengyang can use his robot to complete the main task of this expansion! So Xu Zhengyang immediately controlled his GX-1 engineering robot to the northwest corner of his shelter, turned into a drilling car and began to dig down. Xu Zhengyang prepared to dig another underground floor below his shelter and dig it into a giant space of 300 meters long, 300 meters wide and 5 meters high! Although the walls of Xu Zhengyang's shelter are all made of C120 concrete mixed with fine copper wire. But even this reinforced concrete wall that is hard enough to withstand shells, it cannot withstand the impact of the GX-1 engineering robot in the form of a drill bit! "With the engineering robot here, I can drive it to drill the bank's vault, haha!" Xu Zhengyang said casually, then set up an automatic mining program for the engineering robot, and then went out again. He needs to buy some concrete, fine copper wire, wire, PVC pipe and other building materials back. After all, the second underground floor area is so large that the various building materials needed are not a small number! * When Xu Zhengyang returned home, it was already six o'clock in the afternoon. This time, Xu Zhengyang returned to his timber factory with a semi-trailer filled with C120 concrete. Not only that. There is also a car crane behind the semi-carrier, which is specially used to help Xu Zhengyang unload goods! So much concrete. If there was no car crane to cooperate with unloading the goods, it would take at least a whole day to rely on manpower, Xu Zhengyang would not want to waste time on such trivial matters. Just when the semi-trailer is unloading.
The fine copper wires, wires, steel bars, PVC pipes and other building materials purchased by Xu Zhengyang were also delivered to the door. Fortunately, Xu Zhengyang’s timber factory has a large area, otherwise so many delivery trucks wouldn’t be able to stop! Just as a large number of workers were unloading goods in Xu Zhengyang's timber factory. Sudden. I only heard a "click". All the high-power searchlights in the wood factory went out together! It's already 8:30 . Baicheng is located in the northwest. No mistakes, one song, one content, one in 6, one book, one bar, one reading! In mid-November, the stars were already dark. That's why. As soon as the power outage was out, the masters who were unloading stopped their work and said to Xu Zhengyang: "Boss, tripped!" "Are there any electricians? Find an electrician to change a fuse, otherwise we can't work if we are so ugly!" ... Xu Zhengyang was also very strange. Because his timber factory uses industrial circuits, when the factory was running at full speed, it was more than enough to bring twenty large woodworking machines. Why do a few lights trip now? So Xu Zhengyang immediately went to the distribution box to check. really. It's a power outage or not a trip. So Xu Zhengyang quickly returned to the shelter and took out the diesel generator he had bought before and connected it to the circuit to start it up. After the searchlight lights are on again and the workers continue to work. Xu Zhengyang then had time to call the power supply bureau: "Why is there a power outage on North Fourth Road?" ... moment. Xu Zhengyang hung up the phone with a pale face. From today on, his timber factory will be powered off!
According to the power supply bureau's explanation. The demolition agreement for this large area of Beijiao has basically been agreed, and the first phase of demolition has started to run in advance from Beiyi Road. So start today. The Power Supply Bureau will stop supplying power to all factories outside the residential areas of the Northern Suburbs in accordance with the spirit of the superior documents! When the GX-1 engineering robot is running at full speed, it requires three hundred kilometers of electricity in one hour. The GX-2 large engineering robot, which is more advanced than the GX-1, will probably double the power required to operate! But now. The Power Supply Bureau cut off the power supply in all factories in the northern suburbs. Xu Zhengyang's two engineering robots are no different from two pieces of scrap iron. "well……" Xu Zhengyang sighed and rubbed his temple helplessly, "I have to find a way to solve the problem of electricity..."
