The electromagnetic cannon that Yun Lei asked Tong Guogang and General Shi to experiment with should be called an electromagnetic railgun in a strict sense. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 info This electromagnetic railgun is not the same as a conventional gun. In order to achieve a certain amount of power, it is not necessary to consider complex issues such as metallurgy, gun chamber design, and the expansion rate of explosive gases.

Electromagnetic railgun, if you want to get a certain lethality, you only need to have a strong current, a strong magnetic field, and a certain length of rails.

Yunlei uses aluminum alloy javelins as guide rails, stones as cannonballs, and yin thunder as the foundation for creating a strong current and a strong magnetic field. The electromagnetic cannon constructed in this way seems simple, but its power has surpassed the experimental version of the electromagnetic cannon that has been produced by many countries, including the Mayflower Federation.

The reason is very simple, whether it is Tong Guogang or General Shi, they are already monks in the Dan period. The condensed Yin Thunder, in terms of power, is far more powerful than the ordinary current provided by the generator in the human world. And it's even more powerful. In this trace of thunder, the condensed energy can be fully equivalent to the power generation of a small power plant in a day. And, there's almost no waste of energy.

Nowadays, the manipulation and use of thunder and lightning by human beings has reached an extremely complex and huge situation. However, in the process of application, there is still a large amount of energy, which is dissipated through electric heating or other means. However, these two yin thunders do not have this problem at all.

Every trace of energy in these two yin thunders was under the control of General Shi and Tong Guogang. There is very little waste. Even humans can use electric currents of the same power to create electromagnetic railguns. In the end, the energy that really worked was still less than the Yin Thunder controlled by General Shi and Tong Guogang.

Therefore, when these two yin thunders circulate in the aluminum alloy, the magnetic field that can be obtained is also unusually powerful.

The only regret is that the length of the aluminum alloy javelin is really shorter.

At present, the electromagnetic railguns being studied by the major powers in the world can completely accelerate a projectile weighing 300 grams to 4,000 meters per second, which is already four times that of a gunpowder rifle bullet! It can also accelerate a projectile weighing 9 kilograms to 2,500 meters per second, which is already two to three times that of an ordinary artillery shell!

Yun Lei asked General Shi and Tong Guogang to experiment, the electromagnetic railgun driven by Yin Thunder, limited to the length of the track, although the electromagnetic field obtained is more powerful, but the muzzle velocity of the electromagnetic cannon projectile obtained in the end is only a little higher than this data.

And the Yin Thunder condensed by ordinary Yin soldiers in the foundation building period could not be so powerful at all. The power of the electromagnetic cannon should also be reduced a lot. But even if they are reduced by two or three times, the power of these electromagnetic cannons is at least about the same as that of some ordinary cannons. Moreover, the cost of firing will be much lower than that of artillery. Shells are available everywhere and do not need to be made specially.

In this way, as long as Yunlei has enough electromagnetic railguns, it will be enough to complete the dream of breaking through the ghost city of Fengdu.

Yun Lei was overjoyed when he saw this, and ordered all his Yin soldiers to practice the method of using this electromagnetic railgun. Practice for an hour, distribute heaven and earth spiritual materials, restore the spiritual power of the body, rest for two hours, and then go to besiege the ghost city of Fengdu.

There are 3,000 Yin Ghosts in the Perineal Thunder Technique under Yun Lei, and if they are combined in pairs, they can also make 1,500 electromagnetic cannons. During the training of these three thousand Yin soldiers, they picked up mountains and rocks as cannonballs, and took a low mountain on the Cloud Thunder Planet as a target, and thousands of electromagnetic cannons fired in a salvo, but the roar was deafening.

Where the projectile fell, the hard and solidified rocks shattered and collapsed. After more than an hour of practice, half of the height of the low mountain, which had been subjected to countless cannons, was erased. Huge rocks shattered and rolled down the slopes, submerging the base of the mountain. Everywhere it looks, it's a mess.

And to Yun Lei's surprise, this way of casting Yin Thunder was far smaller than he expected to consume Yin Thunder. These three thousand Yin soldiers, after practicing for an hour without stopping, actually have the strength to spare!

After all, those yin thunders don't catapult out and never look back. In the surge and alternation of the current, although the current itself has a certain loss, it is far more energy-saving than the release and ejection of the yin thunder like a short circuit. That is, this kind of catapulted stone projectile and the like, which has no corresponding restraint against the Yin soldiers and ghosts.

Otherwise, Yun Lei Guang can use these electromagnetic cannons to pile up the 100,000 army of the Ghost King and the Void Phase, where can he use it so troublesomely?

And what surprised Yun Lei even more was that an hour after he returned to the space gourd, Tai Lian had actually prepared all the things he wanted.

In the space teleportation array, not only did a large number of I-beams appear, but more than a dozen strange-looking cars also appeared. It looks like a fire truck.

Yunlei used an aluminum alloy javelin as a guide rail, which was nothing more than an expedient measure. Although this thing can be used, it has a non-slippery curvature and a limited length. Even if several are put together, they are not suitable as guides for projectiles. On the contrary, it is an angular I-beam, which should be very easy to use. Moreover, the length of the guide rail can also be arbitrary.

Yun Lei asked a group of ghosts to try it with this I-beam, and sure enough, the power and accuracy of this electromagnetic cannon were twice as strong as before!

Yun Lei was overjoyed, and asked the red lady to distribute all kinds of heaven and earth spiritual materials that could quickly replenish the spiritual energy, and only waited for the spiritual power in the bodies of the Yin soldiers under her command to recover to a relatively high level, and then took the tens of thousands of Yin soldiers under her hands, and a large number of I-beams that were used as guide rails, appeared outside the ghost city of Nafengdu.

In the experiment, it was bombarded by 1,500 electromagnetic cannons on the broken low mountain, and those shattered mountain rocks could just be used as projectiles for these electromagnetic cannons to fire, and they were taken outside the ghost city of Fengdu by Yunlei together.

At this time, the ghosts in the ghost city of Fengdu were already in chaos. Although the two ghost monks of Wuxiang and Wunian showed their true cultivation, they used the power of the ghosts of the Yuan Infant Stage to suppress the doubts of the ghosts of the Yudan Period. However, the ghost monk was seriously injured and returned defeated.

As a result, this deterrent power can't help but be reduced a lot.

Now, although in the ghost city of Fengdu, there are still two infancy ghosts, Wuxiang and Wunian, but the army's heart is in chaos. The fact that Yun Lei's three thousand Yin soldiers and ghosts engulfed the more than 40,000 Yin soldiers in the ghost city of Fengdu, while he suffered very little damage himself, is undeniable no matter how many Yuan Infant Stage ghosts are shocked.
