On June 2nd, Lu Chen got up and washed up and came to the outside of the shelter, and after checking the solidification degree of the wall, it is expected that there will be two days to solidify, at least the surface can stand people, Lu Chen is ready to use the iron sheet above as the benchmark, and start to install barbed wire and wires, and then after the power is turned on, some people can be blocked, if someone wants to climb over the wall from above, then at least cut the wire, once cut, the inside of the shelter will call the police, so that you know that it is not good, the gate is made of alloy gates, Ordinary means to open the door does not work, ready to write a program, can only be opened by the electronic key, and directly locked after the power is off, unless it is violently broken, don't want to open it, and prepare to add a piece in the program, once it encounters a hacker, it will collapse directly after the permission change, and then the door is powered off, and finally it is your own shelter to prepare some weapons, ready to delay time.

Once encountering an invasion, if he feels that he can't stop it, then Lu Chen will directly report to the official, and then delay time inside the shelter to wait for support, if the criminals run away in the end, then he can be targeted according to these people's methods of breaking down the door afterwards to improve security.

Subsequently, Lu Chen entered the shelter after the installation was completed, and then began to create a server group, first set up a computer room, and the room needs to be larger, so as to facilitate future expansion, at present, it is enough to use the fan in the cabinet to dissipate heat, and the temperature is so low, the temperature in the computer room can be controlled a little lower, so that it can also dissipate heat.

Then Lu Chen used the nanocore to optimize the server group

————

Micro Server Group (within data processing)

Crafting requires 200 energy

Manufacturing time: 30 minutes

Unfolded area: 2 meters high, 0.5 meters long and wide

Single Server Performance:

Running memory: 32GB

Storage: 1TB

Energy consumption: 2.5 kWh per day

Note: A micro server group composed of ordinary servers has only one cabinet, but there are ten ordinary servers inside, and the computing speed is greatly improved under the bonus of ten servers.

Subsequently, Lu Chen first spent 200 points of energy to reopen a space, and a small amount of floor heating was laid on the internal ground, and then Lu Chen created a computer with 20 points of energy, and after connecting to the server, he began to refer to the integrated system of the mall control center to write the intelligent control program inside the shelter.

Because the control center inside the mall is monitored by staff in real time, many systems sometimes need personnel to manually control, which leads to Lu Chen's need to change a lot of places for manual control to program control when referencing, so that Lu Chen can be freed from repetitive work.

In fact, if Lu Chen's body and brain had not been developed by the nano core, it is estimated that he would only be able to download other people's shelter programs on the Internet, but during this period, who knows if this kind of program will have a back door, in case he adds a back door, he doesn't know, and then when he goes out, he enters his own shelter and loots the supplies, then there is really no place to cry.

Then Lu Chen did not go out of the shelter in the next few days, using the system of the mall, through continuous programming and testing, it took 5 days to develop an effective shelter system, in these days, Lu Chen kept developing programs, sometimes writing and writing, he found that the server was not enough, and then he had to increase the server, and then write, just like that, after a few days of high-intensity work, he finally developed a set of systems that he was more satisfied with, which still has a reference situation, If you start from scratch, you probably won't be able to achieve it in a few months.

......

On the evening of June 7th, Lu Chen sat next to the computer and clicked on the program, the equipment inside the shelter began to be taken over by the program, and the equipment and facilities such as the power system, water supply system, air conditioning system, planting system, monitoring and security system and manufacturing system began to operate automatically, and the power balance inside the shelter had entered the warning value, which meant that if Lu Chen did not upgrade the power system, then other equipment could not be added in a short period of time.

Lu Chen came to the computer room, looked at a cabinet in front of him, and felt that the efforts of the past few days were not in vain, now there are 1 row of 5 groups of cabinets in the computer room, a total of 1000 points of energy spent by Lu Chen, through a large number of data simulations, the current intelligent program has been able to stand alone, such as plantations, now through the monitoring and monitoring of intelligent algorithms, through monitoring equipment, intelligent algorithms can analyze the growth status of plants through picture comparison, such as water shortage, insect pests, malnutrition, etc., and then through monitoring equipment, It can ensure the temperature and humidity inside the planting room, as well as the concentration of carbon dioxide, etc., and the ventilation and temperature system inside the shelter can maintain a series of intelligent control of air quality and temperature in the bedroom and living room area through relevant human comfort data.

By eight o'clock in the evening on June 7th, the nano core accumulated a total of 1620 points of energy, and then Lu Chen used up 800 points to create four sets of micro server groups, and then spent another 200 points to add many detection devices to the power distribution room, plantation, water system, monitoring and security system, and air conditioning system, otherwise a lot of information could not be transmitted into the program, and it would be impossible to carry out intelligent calculations and send instructions.

Subsequently, after Lu Chen learned that the power was running low, he consumed 200 points of energy to widen the power distribution room, and prepared to upgrade the generator and increase the power generation after accumulating a thousand points of energy, after all, he had not developed and installed the defense system in the shelter, and he did not plan to use traditional gunpowder weapons, but directly used electromagnetic weapons, so the more electricity, the better.

Then Lu Chen walked to the manufacturing room while thinking, preparing to develop electromagnetic weapons.

First of all, Lu Chen first made a dense coil, and then wound it to an iron pipe, and then after energizing the coil, put a projectile on one side of the iron pipe, and then the projectile was immediately launched by electromagnetic force, but the speed was not very fast, and then, Lu Chen constantly adjusted the coil for testing, and finally found a winding method The speed of the projectile is already fast, after testing, the initial speed of the projectile has reached 2000M/S, and no matter how fast the winding method is, it requires a lot of energy, At the current initial velocity of 2 kilometers per second, the high-energy battery with the specifications on the protective suit can only provide 10 rounds of projectile energy supply, and I use a 50g projectile, and every 10 rounds need to cool the coil, but the power is still considerable, basically high-strength alloy steel can't block a shot.

In the end, Lu Chen imported the manufacturing method into the nanocore, and used the nanocore to make a handful.

————

Homemade Electromagnetic Rifle (Weakened)

100 points of energy required to manufacture,

Manufacturing time: 30 minutes

The length of the whole gun is 88cm

THE INITIAL VELOCITY OF THE PROJECTILE IS 2000M/S

Projectile mass 50g

Magazine capacity 20 rounds

Energy supply mode: dual battery energy supply

Cooling method: air cooling

Description: The weakened version of the electromagnetic rifle that weakens the initial velocity of the projectile due to energy problems, because its coil is not a room temperature superconducting coil, every ten rounds of continuous projectile needs to be cooled for 1 minute, but maintaining the speed of one shot per second can be fired until the energy is exhausted, so what would you choose?

————

Guardian Electromagnetic Rifle (Direct Powered Version)

Manufacturing requirements, energy 300 points (with lifting platform)

Manufacturing time 1 hour

The full length of the gun is 1.5 meters

THE INITIAL VELOCITY OF THE PROJECTILE IS 8000M/S

Projectile mass 100g

Magazine capacity ammunition box feed (10,000 rounds of pellets)

Energy supply mode, cable power supply

Cooling method: water cooling

Description: The large-scale killer electromagnetic rifle built in the shelter, directly powered by cables, plus a circulating water cooling device, can fire a thousand rounds of projectiles continuously before it needs to be cooled under the condition of ensuring sufficient power supply, and its own lifting platform, installed on the top of the building, basically modern armored units will not be able to approach

Lu Chen looked at his remaining energy, and always felt that the nanocore counted his own energy to death, and did not give himself any leftovers.

But complaining and complaining, these things still have to be made, and then, Lu Chen spent 400 points of energy to make two electromagnetic guns, and then used the remaining 20 points of energy to make a batch of projectiles, including 200 rounds of 50g projectiles, and 100 rounds of 100g projectiles.

Two hours later, Lu Chen looked at the two rifles in front of him, which were very similar to the guns held by the motorized infantry in the interstellar squad in the science fiction movie, but this was the Blue Star, and there was no Zerg.

Lu Chen saw that he had accumulated another 20 points of energy, and directly transformed two sets of energy bins, consumed four high-energy batteries, and then loaded the bullets and started to test the gun, but the weight of this gun is still a bit high after it is fully matched, Lu Chen is okay with the gun and does not move, if he goes out with the gun, it will be a burden, so he still needs to cooperate with the protective clothing.

Then Lu Chen waited until 12 o'clock, and used the 20 points of energy he had just accumulated to install the unweakened version of the electromagnetic gun on the roof of the building outside the shelter, and installed a camera to control it with a computer, so that if there was a strong enemy outside, he could directly control the rifle in the shelter to repel the enemy without going out.

......

In the past few days of Lu Chen's retreat, the country's railway transformation has been basically completed, all the locomotives have been replaced with the previous internal combustion engines, and at the same time, each official shelter has laid a railway, which can allow the train to directly arrive in front of the shelter and unload the goods directly.

And with the completion of the transformation of the railway network and the official operation, a battle in the wilderness is about to begin, and the loud noise that Lu Chen heard a few days ago is the prelude, just like everything will have some signs at the beginning.
