The mountain city was destroyed in an instant, Song Qingyuan watched silently, she watched the ruins of the mountain city appear little by little after the mushroom cloud dissipated, and the middle place has now become a huge pit, which looks very terrifying. Pen, fun, pavilion www. biquge。 info

And in the outer cities, only collapsed and shattered buildings remain, like a desert that has never had a city before.

The entire mountain city, including the mountain city survivor base, as well as all the professionals in the midterm, were all wiped out at this moment.

Song Qingyuan saw that her advance progress had increased by fifteen percent, which meant that there were professionals equal to fifteen A-level career ranks who had been wiped out by her.

Now Song Qingyuan's professional advancement progress has reached 20%. One-fifth of the advancement progress was obtained by Song Qingyuan by killing countless professionals, and if she really wanted to advance, then at least she had to kill more than half of the professionals in this country to be able to do it.

Although Song Qingyuan wanted to advance quickly, she also knew what a hundred A-level professional ranks meant. A few A-level professionals can support a large survivor base.

Slaughter, she needs to be slaughtered in order to advance successfully. But that time had not yet come, and in her plan, the slaughter would begin when the era of armed chaos had really begun.

At present, most of the survivors in the country are distributed in the survivor bases formed by various armies, relying on the army to provide protection, but there will always be a day when the ammunition will run out, and the army will collapse sooner or later, and when the base collapses, it will be the advent of the era of melee.

Song Qingyuan teleported back to her Black Lotus base, the mountain city has been destroyed, but this is only the beginning, it won't be long before the new capital base will understand what kind of terrible person they have offended.

Song Qingyuan took out the nuclear bomb made by Li Yue and Wang Han from the void space, although the yield of this nuclear bomb is not large, but it means that she finally has the ability to make a nuclear bomb.

Song Qingyuan looked at Li Yue and Wang Han's design drawings and research materials, the drawings and materials clearly recorded how they made this nuclear bomb, Song Qingyuan, who has a soul power of 100,000, quickly read it and fully understood it, and now she feels that she can also create such a nuclear bomb.

Song Qingyuan came to her laboratory, which is her exclusive territory, with many instruments and equipment, such as high-precision digital lathes, spectrum analysis machines, ultra-dimensional printing devices, etc. The equipment here is the best equipment in the entire new base, and Song Qingyuan has never underestimated the power of black technology.

Song Qingyuan began to make the second nuclear bomb according to the drawings, and the difficulty was not the nuclear raw materials, the nuclear raw materials were ready-made, and they only needed to be melted down and recast. The real difficulty is the manufacture of a housing that meets the requirements.

The shell nuclear material and the controller, these three devices make up the nuclear bomb.

Song Qingyuan began to design the component structure of the nuclear bomb shell in computer software, and she was going to design six parts, process them separately, and then assemble them.

Compared with the four-part assembly designed by Li Yue and Wang Han, Song Qingyuan thinks that her design is more perfect, but at the same time, the difficulty of manufacturing has also increased, but Song Qingyuan is not worried, because her equipment here is better than Li Yue's equipment.

The nuclear bomb designed by Song Qingyuan is also a sphere, because she feels that she does not need to design the aerodynamic part, and it is impossible for her to get a large rocket to launch the nuclear bomb now, so she can only put the nuclear bomb on the target to be blown up by herself, and it does not matter whether it has aerodynamic properties.

When designing a nuclear bomb, the shell is the top priority, so Song Qingyuan spent a long time designing it.

She sat in front of the computer and preliminarily built a three-dimensional model of the nuclear bomb little by little.

The first model was built with a lot of irrationalities, and now it is a draft at best.

Song Qingyuan began to modify on the basis of this model, the difference between the three-dimensional model and the two-dimensional model is that you can think more when you design, and at the same time, it is more brainpower-consuming.

But at the same time, the design process is exciting, as the designer will enter a completely different world and experience the reality of the design.

Song Qingyuan divided the shell of the nuclear bomb into six parts, and the six parts were to be designed to form a perfect sphere, so she first constructed a sphere and then divided it.

After the initial segmentation, the second step begins.

The software used by Song Qingyuan is the advanced engineering software flowing out of the new capital base, and the various functions are very comprehensive, she tries to divide the sphere into structures, and uses codes and tools to construct imaginary structures little by little.

In the end, Song Qingyuan finished designing it.

She divided the nuclear bomb into six parts, the first part is the inner core of the nuclear bomb, that is, the place where the nuclear explosion will occur, which is designed as a smooth sphere, once the six nuclear material balls fall into it, they will roll directly and touch together, the diameter of the sphere is calculated, and the six nuclear material spheres will be perfectly in contact with each other, and through co-reaction, the speed of detonation will be accelerated.

The inner surface of the sphere is designed with the entrance of six nuclear materials, the entrance is a specially designed structure, the straight entrance inner opening, designed to control the opening, after opening the door with elasticity and quick closing, its shape is turbine-shaped, which can make the opening and closing speed the fastest.

The way for nuclear materials to enter the reactor chamber is to catapult to avoid detonation due to the placement of nuclear bombs.

When the detonation order is issued, the power system moves the nuclear material out of the storage tank and into the ejection channel.

A second ejection is then carried out, the entrance door is opened, and the nuclear material is ejected into the reaction chamber instantaneously.

The moment the nuclear material enters the reaction chamber, the six entrance doors are closed, and then the nuclear material comes into contact, and a reaction occurs, and the nuclear explosion is initiated.

The power system used by Song Qingyuan is an electric primary elastic device, because there is no need to consider repeated use, so when ejecting, it can be carried out with maximum power, which instantly consumes a lot of electrical energy and obtains a faster speed.

The design of various valves requires reliable mechanical controls, and Song Qingyuan spent a total of five hours, referring to the design of Li Yue and Wang Han, and finally designed the shell of his first nuclear bomb by himself.

Then, after Song Qingyuan checked that it was correct, she started the digital lathe and began to manufacture the shell.

Three hours later, the shell was manufactured, Song Qingyuan tried to assemble the shell, and after tightening the screws at the last moment, the metal sphere with a diameter of about 30 centimeters was assembled, which looked very mysterious.

Song Qingyuan took the shell weight apart again, and then she took a mobile phone and began to swipe the mobile phone into the new system

This system is very simple, it is a code operating system, specially used to control nuclear bombs, it is Li Yue who designed this system, she used the control system in the nuclear bomb data to design this system, and now Song Qingyuan just checked the code, and then flashed the machine as it was.

Wiring, installing batteries, increasing stability, the control system of a nuclear bomb, although not complicated, is precisely the extremely vulnerable part.

Song Qingyuan has a ready-made electronic catapult, so it only needs to be welded.

Two days later, Song Qingyuan made her first nuclear bomb.

Look at this thirty centimeter diameter metal sphere, there is an exposed switch on it, as long as the switch is pressed, the nuclear bomb will detonate after ten seconds, there is no stop and pause button, once the switch is pressed, it will definitely detonate, unless the nuclear bomb is disassembled within ten seconds.

Song Qingyuan covered the cover plate of the blocking switch, and the sphere turned into a perfect shape, and Song Qingyuan took another paintbrush, ready to paint some interesting things on its surface.

Eventually, Song Qingyuan drew it into a large basketball.

It's a perfect disguise, and no one is going to associate basketball with a nuclear bomb. (To be continued.) )
