Electromagnetic cannon is an advanced kinetic energy killing weapon made by electromagnetic launch technology, compared with the traditional cannon, the use of electromagnetic field generated by the Lorentz force to accelerate the metal cannonball, so that it can reach the kinetic energy required to hit the target, compared with the traditional gunpowder driven cannon, the electromagnetic cannon can greatly improve the speed and range of the projectile, and even the ejection speed of the railgun can theoretically reach sub-light speed.

Ye Yun's imagination is to use the thunder method to control the thunder and lightning, forming a strong magnetic field around him to accelerate the metal bullets, and if the control is exquisite enough, he can even not only fire electromagnetic cannons, but also control metals arbitrarily like Magneto, which is far more cost-effective than directly using thunder and lightning attacks.

The theory of the electromagnetic cannon is not high-end, and it can even be simulated directly with a magnet, and it can be easily searched on the Internet, Ye Yun naturally understands that the only thing he has now is the refined control of thunder and lightning, after all, he does not have the ability of thunder and lightning, but controls thunder and lightning through thunder, so he can't carefully feel the flow of thunder and lightning and the change of magnetic field, so this requires him to practice slowly and be familiar, this is not something that can be done in a while, but the "cannonball" of the electromagnetic gun can start to be built.

Ye Yun's villa also has an underground laboratory similar to Tony's, but his laboratory is not used for scientific inventions, but reserved for alchemy, refining and experimental Taoism, after all, although this is the Marvel movie world, it can't directly use various abilities outside.

There weren't many things in the basement, it could almost be said to be empty, but with a wave of Ye Yun's right hand, there were suddenly a lot of things in the basement, a huge iron block, a pool formed by the rock and several uneven pieces of metal.

Originally, he still needed a forge furnace, but he couldn't find a suitable one, so he had to make do with it, anyway, his Dao fire was high enough for you, even without the bonus of the forge furnace, he could easily melt these metals.

The cannonballs fired by the electromagnetic cannon still have to fly in the air, so they will definitely be affected by air resistance, so Ye Yun decided to make the bullet into a fusiform shape, and he uses it with him, so it doesn't need to be too big, the size of the bullet of the general rifle can be, of course, in order to increase the power, you can also engrave a formation on the bullet.

The material used to refine the bullet is Xingchen steel, this kind of thing can survive near the destruction of the planet, and the hardness can be imagined, but in front of Ye Yun's Dao Fire, it only lasted for a few seconds, and it began to soften.

The big brother fusiform bullet is not a difficult thing for Ye Yun, who can perfectly control every trace of strength in his body, but what surprised Ye Yun was that when he used the hammer of Thor to forge, this hammer of the god of thunder actually spontaneously tempered these forged materials, so that these materials were attached to a trace of thunder attributes, which was simply an unexpected gain.

It took half a day for Ye Yun to hammer out one hundred and nine bullets with Thor's hammer, and then spent another whole day inscribed the formation of these bullets one by one, making these bullets stronger and with various characteristics.

For example, a bullet engraved with a wind circle can use the power of the wind to accelerate the bullet, so that the air will not only not become a drag, but also a boost, allowing him to fly faster; For example, a bullet engraved with a gold circle will form a sharp force at the warhead position, which will be more penetrating than other bullets, and the fire and ice will have a burning and freezing effect.

After forging the bullet, Ye Yun finally walked out of the basement, and at this time, it was already full of stars outside, Ruiwen and the others had already slept, Ye Yun saw this, and didn't want to disturb them, so he took a shower in the guest room on the first floor, and fell asleep, and the hammer of Thor was thrown on the table by him at will.

I don't know how long I slept, Ye Yun's divine sense suddenly came from an alarm, which woke him up, when he unfolded his divine sense, he found that a helicopter gunship was flying up from the cliff, and the record on the plane was that the Gatling cannon had begun to pre-rotate, as long as the trigger was pressed, it could be fired, and if the large-caliber machine gun was enough, it could blast the entire villa into pieces in just a dozen seconds.

"Why does this scene sound familiar to me?" Ye Yun, who had just woken up, observed the plane with his divine sense, and always felt that this scene was a little familiar, as if he had seen it somewhere.

After thinking for a while, Ye Yun suddenly woke up and said loudly: ", I remember, isn't this the picture of the Iron Man Three Middle School and Ten Commandments Gang blowing up Tony's villa?" How did they get to my villa? Did you remember the wrong house number? ”

Whether he misremembered the house number or not, it was already a fact that the plane was preparing and had begun to attack his villa, but all the rockets and shells hit a transparent light film, and the villa did not even suffer a trace of the aftermath of the explosion.

Ye Yun still didn't know what was going on, and what twists and turns there were in this matter, but it was an irrefutable fact that his villa was attacked, so Ye Yun snapped his fingers, and with his snap of his fingers, a bolt of lightning fell from the sky, directly penetrating the helicopter, and detonated the ammunition on the plane, causing a martyrdom, and instantly blowing the plane into slag.

When the smoke and dust dissipated, Ye Yun's villa was still intact, and even the rock wall below the villa was not damaged in the slightest, because even the cliff Ye Yun under the villa was reinforced with a formation, but he remembered that Tony's villa in the play was blown up by a helicopter's rocket and collapsed the rock wall below, and it directly slid into the sea, so he had already entered the reinforced formation in the rock wall, as long as the formation was not broken, this rock wall was like steel.

There was such a big movement on Ye Yun's villa, it was impossible for Tony, who was only less than 100 meters away from Ye Yun's villa, not to know, but in fact, at this moment, Tony was standing in front of the window looking at Ye Yun's villa from afar, with endless happiness and envy in his eyes.

Tony looked at the villa in the distance that was not damaged at all, and said proudly to the little pepper beside him: "Fortunately, I was prescient again, and I hugged the house number of the cloud when I reported the address of the residence, otherwise our villa would be in ruins now, but the defense system of the cloud villa is really powerful, and I will get a set of changes to Ming'er." ”

"Tony, although we have tested the defense capabilities of Cloud Villa before and determined that ordinary small missiles cannot cause damage to it, you are still doing this... Pit (Chinese), right pit clouds, are you not afraid that the clouds will come to you to settle accounts? Compared to Tony's pride, Pepper Potts's face was full of worry.

Tony waved his hand absently and said, "Potts, don't worry, Yun is very generous, and he won't care about these little things, but it's you, let's practice more of the exercises I taught you, so that I can rest assured." ”

Hearing this, the worry on Pozzi's face became even heavier, and he said, "I'm almost cultivating to the second level, but Tony, can you really teach me this without asking the clouds?" ”

Tony turned around, held Potze's face, and comforted: "Yun didn't say that he wouldn't let me pass it on, and judging by his expression at the time, this thing shouldn't be a very valuable thing in his eyes, and you're his niece and daughter-in-law, so it's not a biography, isn't it?" ”

Potz thought about Ye Yunren's personality and usual way of doing things, and finally didn't say anything, but what they didn't know was that Ye Yun in their mouths was sitting on the bed in their villa, facing their direction, and the smile on his face was particularly bright.
