Jin Yang's first thought was the car bomb that would shine in this battle.

"Through the results of this battle, it can be seen that the car bomb converted into a four-meter auxiliary transformer's nuclear fusion engine is quite powerful, as long as it can get close to the Decepticon warriors, it will definitely be killed or injured. It's just that it's hard to guess how much damage it can do to an eight-meter Transformer. After all, there is still a big gap between the small hydrogen explosion produced by the nuclear fusion engine and the hydrogen bomb on the earth, and the defense power of the eight-meter Transformers is definitely not comparable to ordinary Transformers, which can be known from the remains of the Decepticon Transformers excavated before. ”

"It seems that if you want to deal with an eight-meter Transformer, you need at least a six-meter Transformer's nuclear fusion engine."

At present, there are more than forty sets of six-meter Transformers components in Jinyang's hands.

Transformers' accessories, as a kind of consumables, whether it is fighting or training fighting skills, are indispensable, Jinyang has an energy source, and there is no demand for accessories. However, the remaining nine Autobots can't do this, and every time the mechanical body is injured, they must immediately replace the parts on their bodies to keep their combat effectiveness at the peak, so to speak, each of these parts is valuable until they have the production capacity.

More than forty sets of metal fittings seem to be a lot, but after being divided into nine parts, it is just enough, which makes Jinyang a little embarrassed.

In the end, Jin Yang still took out two sets of six-meter Transformer accessories to assemble two car bombs to deal with the upcoming strong enemy.

With the previous assembly experience, it only took half a day for Jin Yang to assemble two enhanced versions of the car bomb, and then used the accessories of the auxiliary transformers to assemble four less powerful ones.

Due to time constraints, after making six car bombs, Jin Yang stopped assembling the work, and he decided to build a high-powered weapon to add a hole card to himself.

Electromagnetic railguns, also known as magnetic railguns and guide railguns, are characterized by using the repulsive force generated between different electromagnetic fields to provide kinetic energy for weapons.

Unlike the traditional cannon on Earth, which acts the pressure of gunpowder gas on the projectile, the electromagnetic cannon uses the reaction force of the electromagnetic field in the electromagnetic system to propel the projectile, although its disadvantages are obvious, and the preparation time is too long. But in terms of rate of fire and range, it has a great advantage, the range is tens, hundreds or more than ordinary shells, especially its power, in the case of sufficient energy, there is almost no upper limit.

Some scientists once calculated that if a projectile weighing 100 kilograms can be accelerated to the speed of light or even faster than the speed of light, then the kinetic energy it generates is enough to break through the earth in an instant.

Of course, the electromagnetic cannon developed by human beings on Earth is far from the extent of destroying a planet.

The concept of electromagnetic cannon has been put forward at the beginning of the 20th century, and by the 70s of the 20th century, the conditions for manufacturing electromagnetic guns were more mature, however, there was still not much progress until the beginning of the 21st century, even the major military powers on the earth were no exception, and at most a few hundred grams of metal projectiles could be sent into space, and the preparation time was still very long, and as for large-scale entry into the battlefield, it was even more far away.

In fact, the principle of the electromagnetic cannon is not complicated, and it can be manufactured at a small cost, but such a "electromagnetic gun" looks okay, as for the power, it is definitely not.

The biggest difficulty of the electromagnetic railgun is that it has extremely strict requirements for metallurgical technology, because the ejection speed of the electromagnetic gun is high, usually reaching several times, dozens of times or more than the speed of sound, strong kinetic energy, for the anti-wear and high temperature ability of the gun barrel, it is a severe test, ordinary metal materials, simply can not bear such a burden.

For the current Jinyang, the problem of metallurgy can be solved.

Perhaps, he can't build a super electromagnetic cannon that can penetrate planets, but if he just makes an ordinary high-powered electromagnetic cannon, with the metallurgical technology of the planet Cybertron, it is completely enough.

……

The electromagnetic gun is divided into several parts, namely the power supply, the rails, the shells, and the control system.

First of all, a powerful power supply is needed to charge the electromagnetic cannon, and there are many machines and equipment in this spaceship, as well as a lot of metal source materials, which are enough for Jinyang.

Jinyang pooled the fusion engines, provided kinetic energy through a newly manufactured generator, and let the generators generate electricity, which was converted into the required electrical energy, and then used the existing materials, using Cybertron's metallurgical technology, to produce the barrels and shells .......

A few days later, a strange-looking weapon appeared in the open space outside the spaceship.

In order to further increase the accuracy of shooting, Jin Yang also added a 20-meter-long thick cannon barrel, which was integrated with the rear guide rails and was mounted on a circular rotating base below. On either side of the electromagnetic gun, an average of twenty fusion engines and ten high-power generators are placed as power sources; There is also a computer with an intelligent program installed, which works with the radar to form a comparison system.

Below are the brackets made of eight cars, which are responsible for carrying the weight of the electromagnetic guns.

The entire electromagnetic railgun is very large, like a hairy crab assembled from metal parts, taking up a lot of space on the ground.

Jin Yang circled around the electromagnetic railgun he had just made, wondering in his heart, how did he look like an eight-legged monster? Paired with a twenty-meter-long barrel, it looks like a crab with a cigarette in its mouth, and can't help laughing at himself:

"It seems that I really don't have any artistic cells, and even the electromagnetic cannon I made is so abstract."

Fortunately, the electromagnetic cannon in front of him, although it is not good-looking, is not weak at all.

This 150-ton electromagnetic cannon can instantly accelerate a 10-kilogram metal projectile to a discharging speed of 50 kilometers per second, and under the condition of charging in advance, it can shoot ten shells in one minute, which is enough to hit an eight-meter intermediate transformer in an instant, and if it hits the vital part, it is also possible to kill it directly.

The only thing that displeased him was that the electromagnetic railgun in front of him, with eight "legs" open and a diameter of thirty meters, the width of the tunnel, could not be passed at all, let alone let it participate in the battle of the ground castle.

Jin Yang made it for the purpose of sniping the Decepticons, and it was obviously impossible to play the role of an electromagnetic cannon when placed underground, and after thinking for a while, he was about to disassemble it into parts and bring it to the ground.

And at this moment, the warhead, which was responsible for digging the tunnel, sent a message:

"Jinyang, the tunnel is almost dug up, come and see if you can use it."

So fast? Originally, Jin Yang thought that it would take half a month for the nine Autobots to dig out the tunnels connecting most of the castle, but he didn't expect that it would take only six days to get it done.

"I underestimated them."

After thinking about it, Jin Yang decided to go up and take a look first, the tunnel was the key to fighting the Decepticons, so he had to pay attention to it, and the electromagnetic railgun could be dismantled later.

With a heartbeat, "Boom-Cool-Click", it transforms into a five-meter-long golden sports car, and drives along the upward spiral tunnel to the castle on the ground.

More than half an hour later, Jin Yang came to the street on the ground of the castle, waited for the warhead there to meet him, and said:

"Jin Yang, you come with me".

Following the warhead to a garbage heap, a hole with a diameter of three meters was opened at the junction between the garbage mountain and the house, which was more than 30 meters high.

Jin Yang and the warhead bent down to drill into the hole, only to see that the tunnel inside was more than six meters high and more than four meters wide, and the Autobots could pass through the height of six meters, and some key parts were also briefly reinforced to prevent collapse.

At a depth of ten meters, the narrow tunnels crisscross like spider webs, covering most of the castle, with a total length of more than 200 kilometers, and dozens of hidden exits have been established except for the castle's perimeter.

Inspecting the construction progress of the tunnel, Jin Yang was greatly impressed by the work ability of several subordinates, such a large amount of work, God knows how they got it.

"How is it, Jin Yang, has it met your requirements?" The warhead on the side asked a little proudly, digging tunnels is his forte, in order to open up tunnels, he has not bothered much in the past few days.

Because Jin Yang's prestige in the team is getting higher and higher, and his own strength is strong enough, it is difficult for him to set off the idea of challenge, so he wants to find it from other places and show his ability, just like he has something to be proud of, and always hopes that his friends around him will know, at this time, the warhead is such a mentality.

Jin Yang did not know the idea of the warhead, but he still gave his results an affirmation:

"Very good, I'm sure it will surprise the fanatics, you keep digging, preferably covering all areas of the castle."

The warhead nodded "Okay".

"Warning, Intruder Found, Intruder Spotted"

The early warning from the computer in his body made Jin Yang stunned, it came so fast?
