The group of corpses outside Xu Zhengyang's shelter is not the kind of ordinary zombies who act only by instinct. They also have characters such as "commander" or "military". That's why. When they found out that their team was being "free" by Xu Zhengyang, they immediately chose to break it into pieces! I have to say. These blood plague monsters have very high execution ability! In just less than a minute, these zombies scattered from the initial large-scale zombies into scattered single zombies! So. Even if Xu Zhengyang continued to manipulate unmanned bombers to throw white phosphorus bombs, the results of the same ammunition were only one-tenth of that before! "I'm pretty smart." Xu Zhengyang sneered when he saw this. It's at this moment.

An agile monster rushed to the shelter within five kilometers! The radar on the ground of Xu Zhengyang's shelter rotated at high speed, and red dots representing monsters appeared on the radar display! “biu!” “biu!” “biu!” ... With radar ranging, Xu Zhengyang's slide-rail 7mm laser defense system can operate in full without reservation. Lasers accurately hit bloody monsters. The blood plague monster just chose to break it into pieces, although it made Xu Zhengyang's air strike not worth the effort, so he had to give up. But after it spread out. These single monsters actually facilitate the slide-rail 7mm laser defense system to shoot accurately! Even if one or two fish that escaped the net rushed to the outside of the shelter wall. "Da da da da da..." As soon as Xu Zhengyang fired the four M2 Browning heavy machine guns placed on the shelter watchtower, these monsters will be instantly shot into sieve! ... Half an hour later, the clouds sagged and the rain stopped. When the group of corpses that arrived first were resolved by Xu Zhengyang, Dabai suddenly said to Xu Zhengyang, "Master, please be careful. There are three corpses of the same size approaching our refuge in three different directions. Calculated according to my model.

The recent corpse group is expected to enter the attack range of the slide-rail 7mm laser defense system in 13 minutes and 21 seconds. But this one is the biggest threat…” Dabai said. A real-time surveillance image was projected on Xu Zhengyang's contact lenses, in the group of corpses southwest of the shelter. There are six blood-epidemic giant beasts thirty or forty meters high! "Is the attacking team composed of giant beasts? Xu Zhengyang became interested after seeing this scene, and immediately manipulated his drone array to take off and rushed towards this attacking team composed of blood-epidemic beasts! ... These days. Xu Zhengyang designed various drones with different functions. What satisfied Xu Zhengyang the most was the mother-child drone he named it "magnetic rod". The mother of the magnetic rod is a "big belly" drone with a length of meters and a maximum flight speed of 320 kilometers per hour. Inside the belly cabin of the mother machine. It is equipped with 22 sub-machines that abandon all fancy functions and, while ensuring the ultimate flight speed, fill up C4 as many sub-machines as possible! To lose weight, load more C4s. The battery pack of the sub-machine is very small and can only fly up to 10 kilometers. When the mother machine throws the child out of the abdominal compartment by ejection, the child can instantly reach a flight speed of 560 kilometers per hour! Such a speed, such a simple plane. Even if the elite drone pilot is used to control it, its hit rate will be low. But Xu Zhengyang is different. He has the ability to quantum mapping, and the drone is like an extension of his body, like an arm instructing him! In addition, Xu Zhengyang can also use the skill of focusing on slowing down time flow, which can give himself more reaction time. Therefore, under his control, the magnetic rod and mother drone can fully exert the power of the theoretical upper limit! ... "Boom! Boom! Boom! Boom..." Xu Zhengyang flew out a total of twenty magnetic rods and mother drones. When all the sub-machines accurately blow up the blood-plague giant beasts, no matter how rough the giant beasts are, they will vent more and intake less. After solving the blood epidemic monster attack team, cleaning up the remaining ordinary monsters is as simple as eating and drinking water for Xu Zhengyang.

The monsters did not even touch the walls of Xu Zhengyang's shelter, and fell on the way to charge one after another. After the last zombie in the tide was solved by Xu Zhengyang, a series of system subtitles finally appeared in front of Xu Zhengyang: [Main mission: Bloody zombie tide (in progress)] [Reward: Sanctuary plug-in·Energy gathering optimization] No mistakes, one song, one content, one in 6, one book, one bar, one reading! ... 【Sanctuary plug-in·Energy gathering optimization】 【Effect: After equipping it in the shelter control center, the overall energy consumption of the shelter will be reduced by 20% without affecting performance】 The electricity that Xu Zhengyang’s shelter now consumes every day is an extremely terrifying number! Planting areas, various production lines, transmission platforms, electromagnetic shields... There are many things. No matter which of the things in Xu Zhengyang’s shelter is a big power-consuming user, and it cannot be stopped! "Yes, yes." After seeing the properties of the shelter plug-in, Xu Zhengyang nodded with satisfaction, and immediately equipped it in the shelter control center. After doing all this. Xu Zhengyang then clicked on his task list to view the latest main task: [Main task: Expand V (in progress)] [As you grow rapidly, the existing space of the shelter can no longer meet your next needs. In order to ensure the normal development of the shelter, please expand the shelter again! 】 [Task Objective: Maintain current building standards and expand the area of ​​your shelter to 100,000 square meters] [Task Reward: Energy-Clustering Electromagnetic Cannon (Design Drawings)] After reading the details of the task, Xu Zhengyang did not hesitate and immediately issued an order to Dabai, saying, "Keep the current construction standards and expand the shelter to 100,000 square meters!" "Okay master." Dabai agreed and sent an engineering plan to Xu Zhengyang's contact lenses, and said, "From my model to calculate in real time. With our current productivity, it takes about 57 days and 21 hours to complete the entire project. ” "Have you been in the past two months?" Xu Zhengyang was very dissatisfied with the time, so he asked Dabai again, "Didn't we build a new heavy factory?" How much can the construction progress be improved by using the production capacity of heavy factories to produce engineering robots? ”

"It will take 18 days and 12 hours at the fastest time." Dabai said, sending the optimized solution to Xu Zhengyang's contact lenses. Xu Zhengyang quickly browsed the new plan. Confirm that Dabai had compressed the construction period to the extreme and there was no room for improvement, so he said to Dabai, "Then let's start now!" "Okay master." Dabai agreed and immediately began to expand the shelter.
