At ten o'clock in the morning the next day, Lu Chen got up and saw that the energy had accumulated to 100 points, and then used the energy to make 1000 rounds of 100g projectiles and load them into the ammunition box on the roof, and then came to the roof, opened the lifting platform, and after turning on the function, Lu Chen controlled the aim at the boulder in the distance, and with a short and low sound, the boulder was smashed by the projectile, Lu Chen saw this power, and secretly smacked his tongue,

"It's too ferocious, it is estimated that the tank can't carry such a powerful force, so I'm not afraid of others attacking my shelter."

Then Lu Chen put away the electromagnetic gun and returned to the shelter

......

Just when Lu Chen returned to the shelter, in the border area of the Dragon Kingdom, one by one the patrol teams buried a small device into the ground, this device will be detected when someone enters the country, and then passed into the border outpost, but generally no one will cross the border in this kind of weather, and those who can cross the border in this environment are not ordinary people, so this device is to guard against these people,

And in the mountains not far from the border, there is the underground military station of the border guards, and the internal soldiers will take turns patrolling the border in protective armor.

At the same time, in the space base, a towering carrier rocket has just finished refueling, and it will be launched soon, and now because of the blockage of volcanic ash and the impact of high-altitude nuclear explosions and meteorite impacts, communication with satellites has come and gone, and even electromagnetic communications have received great interference, only wired communications have not been affected for the time being. At the same time, because of the previous nationwide transportation operation, the supervision outside the shelter was a little lax, which led to the birth of a group of criminals, after all, those who can enter the shelter are innocent people, so some lawbreakers are afraid of being liquidated, so they are in an empty place to keep warm, and sometimes they will plunder some personal shelters with low vigilance.

Therefore, if the quantum satellite is launched, it will directly connect various local shelters, form a tight network, and directly send troops to clear illegal armed gangs in the wild.

With the passage of time, it has come to the final stage of the launch, and it can be seen at the scene that the shell of the rocket is very different from before, with a protective shell added to the outer layer, and with a countdown, the fire begins to rise in the air, and as the altitude gets higher and higher, after the rocket passes through the volcanic ash, the connection with the space base has been interfered with.

"Turn on the intelligent program of the rocket and let the rocket enter the automatic state" With the order of the chief engineer, the staff switched the rocket to the automatic state, and half an hour later, the quantum communication system of the space base received a connection request from the quantum satellite.

Then, when the staff connected the connection, the picture of the universe was directly displayed on the screen.

"Report to the chief engineer, the satellite has been successfully connected, check the status of all systems is normal, and the launch task is basically completed," the chief engineer immediately commanded with the report of the staff

"Point the camera at the blue star and activate all the quantum communicators at the same time."

"Yes! Turn the satellite, point the lens at the blue star, 3, 2, 1, the lens has been turned, turn on the satellite quantum communication activation device, 3, 2, 1, the quantum communication system has been activated. ”

With the operation of the staff, the large screen in front is divided into two pieces, the left side shows the satellite monitoring screen, and the right side shows the map of the Dragon Kingdom, and the dense communicator points on it have begun to gradually light up, representing that the quantum communication devices across the country have been activated, and the equipment buried by the patrol team located at the border has also been connected to the communication system.

Subsequently, the capital shelter connected by the chief engineer at the scene reported to the commander-in-chief that the launch mission had been a complete success, and at the same time, the military headquarters connected with the satellite handed over the authority of the satellite to the military department and government departments, and at the same time prepared for the next round of launch tasks.

......

Just after the transfer of satellite authority, the administrative department has successfully connected the shelters and began to coordinate the material reserves between the shelters, and at the same time, the railway department has been able to monitor the location and movement of all operable gas locomotives, and began to coordinate the transportation forces, and finally, the public security department began to issue a notice to the shelters, ordering the special police brigades to start cracking down on illegal armed gangs outside the shelters on the spot, ensuring the control of public security in various places, and at the same time opening the official shelter trading venues, and establishing a credit point system. After exchanging credits for items, you can redeem them for items in the shelter.

......

Tingcheng, the city where Lu Chen is located, the special police team station inside the official shelter, with the sound of an emergency assembly siren, the members of the special police team began to assemble quickly, and then, Chang Lihua, director of the Public Security Bureau, and Liu Dong, the captain of the special police team, came to the team

Director Chang Lihua began to carry out pre-war mobilization:

"Comrades, the higher authorities ordered us to start clearing the local illegal elements on the spot, according to the reconnaissance of the intelligence department, a group of criminals located in a shopping mall has been identified, the criminal gang has self-made guns, so everyone should pay attention to safety when acting, we must defeat this gang to ensure security around the shelter."

Subsequently, the captain Liu Dong issued a combat order:

"All of them, bring their gear, and gather and set off in ten minutes."

"Yes!"

The SWAT team members then went back to collect their equipment and began the operation.

......

Here Lu Chen returned to the shelter and found that the things that he could temporarily upgrade had been upgraded, and then began to count what facilities his shelter already had and what facilities needed to be upgraded:

————

Power system: small geothermal generator, providing 200 kWh of electricity per hour, biogas generator motor (newly built, not yet activated due to lack of biogas), (you should upgrade the power generation, set a small goal, increase the power of the generator set to 2 MW)

Water supply and drainage system: The water supply system based on the geothermal generator can meet the daily water purification of 5 tons, and the sewage is discharged into the biogas plant for power generation and fertilizer use (become a manure digger, Sao Nian)

Air conditioning and ventilation system: The ventilation system with industrial oxygen concentrator as the core can meet the oxygen needs of 10 people. (Lonely boy, maybe you need a partner)

Planting room: automated greenhouse plantation, the planting room that has been automatically operated by intelligent programs, currently planting cabbage and lettuce, can produce 400kg of cabbage and 100kg of lettuce per month (more than enough if you eat it yourself)

Manufacturing room: A humble manufacturing room with a metal 3D printer and a multi-purpose processing platform that can process parts up to one meter in length (maybe you need to upgrade it)

Security monitoring system: infrared induction alarm device based on monitoring equipment, with intelligent algorithm as the core, can find life forms and large moving objects close to the shelter, (maybe you need to add an air defense system)

————

Lu Chen found that with the current speed of energy collection in the nano core, it still takes a long time to upgrade these systems, it is the end of the world, ordinary metals and other materials are very easy to collect, but some special materials are under national control before the end of the world, let alone the end of the world, so you can only use energy points to directly convert, the conversion between energy and matter can be realized with the internal mass-energy converter of the nano core, but there is not much energy after the conversion of ordinary matter on the earth, It is better to rely on the energy harvesting device that comes with it to collect energy by itself, in the same way, the use of energy to convert matter will also lose a lot of energy, in the advanced civilization, the nano core conversion material is because there is a large amount of energy support, and the advanced civilization extracts advanced energy is still very easy, so it can be used in some places.

Lu Chen then prepared to go out again to look for supplies, this time the goal was to find a truck to use as a future car, and at the same time search for a large number of metal supplies, but also to find out if there were any other private shelters, maybe some deals.

——

With Lu Chen's departure here, the SWAT team also set off, after half an hour's journey, the SWAT team approached the lair of criminals, as the drone lifted off, using the thermal imager carried on the drone, clearly saw that there were more than ten figures in the underground civil air defense project, after determining the location of the criminals, the SWAT began to sneak into the building,

Then, with a burst of gunfire, the movement inside subsided, and then the temporary command post received a report from the special combat crew:

"Command, this is the Falcon Squad, the situation is under control."

"Command received, how are the casualties at the scene?"

"Report to the command, no one of our fighters was injured, 12 enemy personnel, 8 people have been killed on the scene, another two are in the hands, and the remaining two have given up resistance."

"Command receives,"

Subsequently, the command sent ordinary public security officers into it and began to clean the scene.

And just when the SWAT was operating, Lu Chen found a shelter in Lu Chen, but the gate of this shelter had been destroyed, the materials inside had been looted, and the facilities inside had also been destroyed.

Then Lu Chen checked and found that there was nothing usable and then continued to set off, and after Lu Chen approached the combat site of the SWAT team members, he happened to see a group of policemen pressing two in front of him, and two of them carrying him out behind, and at the same time, Lu Chen was also found at the command post,

Then the SWAT team members surrounded him, pointed a gun at Lu Chen, and asked him to get out of the car, Lu Chen saw this situation and quickly got out of the car and raised his hand and shouted: "Uncle policeman, I'm just passing by, don't treat me like this,"

After Liu Dong, the commander of the SWAT team here, came outside, he saw the protective clothing Lu Chen was wearing, asked the SWAT team members to put down their guns, and then apologized to Lu Chen.

"Little brother, don't be nervous, we're fighting criminals, it's all a misunderstanding just now,"

"Shocking me, I just found a destroyed shelter on the way here, and I guess this group of people did it."

After Lu Chen cleared up the misunderstanding, he immediately reported his findings on the road to Captain Liu Dong.

"Thank you little brother for the information, we are still cleaning the battlefield here, you have nothing to do on your side, so go back to the shelter early, and pay attention to safety when you are in the outside world."

Then the captain Liu Dong talked with Lu Chen for a while, and then let Lu Chen leave

"Captain, let him go so easily?"

Watching Lu Chen leave, one of the special combat team members asked

"This person is not simple, you look at the protective clothing he wears, although there is no protective armor we are equipped with, but it is estimated that it is not something that ordinary people can make, I observe the way he walks, there should be a power-assist device inside, and look at the device on his back, it is estimated that it is a battery, and the rabble inside should not be in a group."

The captain looked at Lu Chen's departing back and explained to his team members

"Besides, the other party is not sure whether he is a criminal now, we will not let go of a bad person, but we can't wronged a good person, so with the current observation, there is no problem for the time being, in addition, after going back, let the intelligence department check this person, although there is no problem now, but with his equipment, this person is not simple."

"Yes!"

Then the captain took a look at Lu Chen, who was getting into the car in the distance, and returned to the temporary command post

——

Here Lu Chen breathed a sigh of relief after getting into the car,

"It's too dangerous just now, almost lost my life, this feeling is too bad, hurry up and search for supplies and go back, and continue to climb technology in the shelter."

Then Lu Chen started the car and left here
