Chapter 134： Chapter 182183

Chapter 134 Chapter 182183 This is not a drill (monthly ticket plus X2)

Busan, the first port and second largest city of Goryeo, was once one of the busiest ports in the world.

At this time in Busan, there is no freighter coming and going at the port; in the city, there is no congested street; in the tall buildings, no noisy people are seen.

Instead, there are various warships, armored vehicles, ground artillery, and temporary military fortifications.

The crowd has already evacuated to the nearby area, which is about to become a battlefield for humans and Zerg.

The eyes of the world are gathered here again, and the last failure happened only a day ago.

The industrial strength of Sakura Country is stronger than that of Goryeo. Even with the help of White Eagle, can they really hold it?

In the combat headquarters, commanders are urgently discussing countermeasures. The experience of another war yesterday can be used immediately today.

How to block the attack of the three beetles has become the main point of their discussion.

"Beetle defense is amazing. In close-range offensive and defensive battles, tank fragmentation shells and armor-piercing shells are more effective against beetles than short-range missiles. We need to stock a large amount of fragmentation shells and armor-piercing shells."

……

He Xingzhou did not pay attention to this war, because the insects are also approaching the magic capital. At the current speed, within fifteen days, they will be able to come down!

At this time, most of the Great Wall of Steel in the Modu Section has been built, and it should be barely completed in 15 days.

This is not enough!

Thousands of red beetles, blue beetles, plus a hundred black beetles, with mutant creatures, broke through the defenses of Chaozi District.

What if there are more Zergs coming to the magic city, and stronger?

"There is no problem with the Great Wall of Steel blocking mutant creatures and first- and second-level Zerg." He Xingzhou thought, "The third-level Zerg has some difficulties. The fourth and fifth-level Zerg, such as the black beetle. Just rely on artillery shells and missiles. It may not work!"

"In case there are other more advanced Zerg... the risk is too great! We must upgrade our weapons and equipment as soon as possible."

The research and development of weapons in the Xuanwu Project started long ago. He Xingzhou originally wanted to improve the laser weapon first, but the appearance of the beetle made him change his mind. He wanted to improve the electromagnetic gun first!

The advantages of laser weapons and electromagnetic weapons are different. Suppose you are fighting a level 5 black beetle. The laser weapon needs to burn it for several seconds before it can be burned to death.

The kind of laser weapon that can evaporate it instantly, it is naturally impossible to make it now.

And the electromagnetic gun can obtain great kinetic energy in a short period of time, even if it is a fifty-meter-thick steel plate, it can smash a big hole! It hits an instant burst, and the laser weapon is more like continuous output.

"In coastal defense battles, although laser weapons have a long range of attack, they are easily affected by sea water and weather, and cannot instantly kill beetles. In contrast, electromagnetic guns are now more lethal to beetles."

He Xingzhou analyzed it and decided to improve the electromagnetic gun first.

He called out the Quantum Optical Brain and opened the weapon technology tree.

"Unlocking the basic induction electromagnetic cannon requires 300,000 units of energy."

"Unlocking the basic electromagnetic railgun requires 500,000 units of energy."

"Unlocking the basic plasma electric cannon requires 700,000 units of energy."

"Unlocking the basic electromagnetic heavy (two beeps) connection cannon requires 1 million units of energy."

One of the basic induction electromagnetic guns, Shenzhou has already mastered the relevant technology, and He Xingzhou directly entered the data and unlocked it.

However, this electromagnetic gun is fixed in the barrel with an accelerating coil. When an alternating current is applied to it, the alternating magnetic field generated will induce current in the projectile coil. The magnetic field of the induced current interacts with the magnetic field of the accelerating coil current to generate an electromagnetic field force to accelerate the movement of the projectile and launch it.

The electromagnetic railgun is to lay electromagnetic rails. After the current is applied, the rails generate a strong magnetic field. Under the action of ampere force on the energized slider, the projectile will shoot out at a very high speed, theoretically even reaching the sub-light speed.

The lethality of the electromagnetic railgun is also very strong, but if it is to be manufactured now, it will face a problem, that is, the ultra-high lethality and the need for a longer acceleration orbit.

The plasma electric cannon uses high-pressure plasma heating to push the shell forward.

As for the final electromagnetic reconnection gun, its principle is the same as the coil gun, but it uses another method of continuous reconnection.

It combines the advantages of coil guns that can launch large-mass projectiles and railguns that can launch super-high-speed projectiles, and can give the projectiles a higher peak acceleration, making it more powerful!

At present, the mainstream in the world are induction electromagnetic guns and electromagnetic railguns, and there is no mature electromagnetic reconnection gun.

He Xingzhou unlocked all four types of electromagnetic guns in one breath. These electromagnetic guns are used in different scenarios. It is not said that one is stronger than the other, but the manufacturing difficulty is different.

In the current situation, the most suitable one is the electromagnetic reconnection gun, which is more powerful and does not need to create an ultra-long electromagnetic track temporarily. Its turret is a rectangular parallelepiped structure and can be manufactured in a short time.

Recently, the unit energy of quantum photobrain is quite sufficient, because a nuclear power plant has been built along the route of the Great Steel Wall, and He Xingzhou has obtained a new source of energy.

He Xingzhou digested and understood this information, and directly contacted the Electromagnetic Weapons Research Institute in the cloud to bring the team responsible for researching electromagnetic guns into the channel.

"Everyone, I have found a way to design an induction electromagnetic gun!" He Xingzhou said.

"Which way?" Questions about Bao Xiangbei, the team leader. He is an electromagnetic weapon expert and has led the team to design many electromagnetic weapons.

He Xingzhou said: “The two positions are designed to be composed of rectangular coaxial coils on the upper and lower sides, with a gap between them. The emitter is a rectangular parallelepiped that can pass through the gap between the two coils for acceleration.”

"Because the projectile carries a continuous current, the magnetic field generated by the projectile seems to "cut off" the magnetic field of the acceleration coil when it passes through the acceleration coil, and then abstractly reconnects with the magnetic field of the next coil."

"In this process of repeated reconnections, the projectile is continuously accelerated, and at the same time it has gained the advantages of induction electromagnetic guns and electromagnetic railguns!"

Everyone understands the principle. He Xingzhou sent a structural diagram he designed.

This is a cylindrical electromagnetic reconnection gun, which is mainly composed of a cylindrical armature, which is wound by a cylindrical asynchronous induction coil.

By controlling the current, the effect of electromagnetic acceleration and magnetic field reconnection is achieved.

"With this design, if we can precisely control each reconnection! Then the projectile can continue to accelerate in a small volume, and finally achieve the same effect as the ultra-long-distance electromagnetic railgun!" Bao Xiangbei said, "We have to try immediately a bit!"

He Xingzhou said: “It’s best to make samples immediately. If the test is successful, mass production will be sent to the front line immediately!”

Bao also knows to the north that now is a time war and needs to race against time.

He immediately said: "We will start now, once the test is successful, we will start manufacturing immediately!"

……

When they were studying the electromagnetic reconnection of the gun, the battle in Busan had already begun.

The previous process is similar to that in Chozi District of Sakura Island. The Zerg first uses low-level mutant creatures to attract artillery fire, and when it is almost consumed, it sends beetles to land.

Because of their previous experience, they were not so embarrassed to deal with this time.

The specially equipped tank armor-piercing shells and armor-piercing shells caused a lot of damage to the beetles, but when the black beetle landed, the damage of the tank armor-piercing shells and armor-piercing shells to them was also limited.

Entering the sea, the Zerg attacked the fleet, and several battleships were destroyed.

"Hold on for another half an hour, the mutant creature is almost dead!" Commander Jin Chenghuan shouted in the headquarters.

"We must defend the coastline!"

The first batch of black beetles that landed was killed by them. There were only less than fifty left. If they survived, they would still have a chance to defend.

But something desperate happened. Originally they thought that there would only be a batch of black beetles, but in the ocean, new **** spots appeared, a batch of more black beetles appeared, and there were all kinds of red beetles behind them. There are estimated to be six to seven thousand green beetles in total.

That scene is like countless heavy armored vehicles charging towards the defensive line!

Underwater, those giant zergs are also attacking the line of defense.

The drone shot, a tentacle tens of meters long appeared in the water, tying up a small ship and pulling it directly into the sea!

"Boom!" A Tomahawk cruise missile hit it, and a large patch of scarlet appeared in the ocean, but the guy did not come up, but disappeared into the water.

Deep water, monsters slammed into underwater interception nets, and some of them could carry electric current. The interception nets had collapsed and the entrance to the sea was breached.

The commander of the White Eagle looked at the situation of the defense line and said: "Retreat, our missiles are ready."

"Retreat!" After Jin Sung-hwan gave the order, the whole person seemed to lose strength.

This is Busan! Unlike the Choshi District of Sakura Island, even if all the beetles are blown to death after retreating to the land line of defense, the city will suffer heavy losses!

And the monsters have opened the entrance to the sea, starting from the Nakdong River, they will enter the island.

Greater disasters and chaos are coming!

Their soldiers retreated to the land line of defense, and countless missiles fell, blowing up the Zerg around the coast line of defense!

Together with it, there is the first port on the island that was once prosperous!

"Busan, has fallen!" At this moment, countless islanders were crying.

"Our home is gone!"

"Zerg has entered the river and will go straight to the inland!"

"What shall we do in the future?"

No one can give the answer...After surviving with a broken arm, they are greeted with more confusion and fear!

……

"Twice, two coastal defenses, all failed!" The entire human world was shaken by this!

Although these two places are not large in size, they are both top industrial and technological powerhouses in the world.

With their military strength, they can’t even guard the entrance to the sea in front of the Zerg.

If the Zerg lands from other places, can they hold it?

Pessimism is spreading in human society, and some people even begin to feel desperate, preaching that the end is coming, saying that they will give up resistance, or go to heaven before the Zerg comes.

Some people start to indulge. Instead of being wiped out by the Zerg, it is better to be happy before death.

Some people and organizations have begun to call on all mankind to unite against the Zerg! Develop more advanced military technology and so on.

Various kinds of phenomena are emerging in endlessly.

A piece of news has brought the world’s attention to China again.

"The third zerg has approached the magic capital of China! I am afraid it will land in ten days!" International media reported the news.

"There is no way! Humans are not the opponents of Zerg at all. Run for your life, you guys!"

"Assimilate the experience of the previous two times, you can directly abandon the magic capital and use missiles to kill the Zerg!"

"The end of the world has come. Only those who believe in the **** of Oran can get shelter and liberation!"

"Mankind has completely abandoned the ocean and retreated to the inland!"

"Hey, this time, many people will die again!"

There are countless pessimistic news.

Because of two failures, even Chinese netizens felt the oppression of the Zerg.

They couldn’t help but also wondered, "Can we really keep it?"

There is another news. It is said that the number of Zerg who attacked the Demon Capital this time is larger than the number of the two Zerg who fought before, and more than they combined.

This news makes people restless.

"So many Zerg, what can I do?"

"The magic capital must not be lost, otherwise the Zerg will soon spread across the country through the Yangtze River!"

"On land, even if there are zerg and mutant creatures, we can still kill them. But if it's in the river, how to catch it?"

"The demons have more than 20 million people. How can we retreat? And it is one of our economic centers. If we go to Choja and Busan once, we will be hit hard!"

People all over the country are paying attention to the magic capital.

At this time, the Xuanwu executives issued a message: “Through the day and night struggle of the masses of people and soldiers, we have completed the construction of the Great Wall of Steel along the coastal section of the magic capital.”

"The Great Wall of Steel is ready to use, we will protect the safety of the magic capital!"

As soon as the news came out, people were immediately excited a lot.

"It was built so soon! What a miracle!"

"We have the Great Wall of Steel, so we should not fail like they did!"

"The Great Wall of Steel has to be tested before it is built. I hope it can become a solid barrier for us!"

"@魔都, come on, we are with you!"

……

The Zerg group is getting closer and closer. Near the sea, the basalt forces dispatch ships and fighter jets to bomb them every day to minimize the number of mutant creatures and Zerg.

At the Institute of Electromagnetic Weapons, the electromagnetic reconnection gun designed by He Xingzhou was successfully tested and delivered urgently for manufacture.

He Xingzhou requested that at least one hundred electromagnetic reconnection guns be built within ten days.

In addition, he also specially designed a large multi-stage electromagnetic reconnection gun, which uses magnetic field superposition to double the thrust of the projectile, and the power will be dozens of times more than those single-stage electromagnetic reconnection guns!

In order for it to be manufactured before the battle began, He Xingzhou personally went to the military factory to guide the manufacturing process.

Eight days later, the magic capital.

Most high-rise buildings that are close to the sea are already empty, and people have already evacuated.

And the huge magic city circle, naturally there is no way to evacuate all, most areas still have to live and work normally.

Before five o'clock in the morning, many people were still asleep in their sleep. At this time, the harsh sirens cut through the sky. Then, all the streets, communities, and houses sounded the same sound.

This is an air defense alert, and this is not a drill!

Thank you *Security Center, Antique 1417, Qi Hensan and other book friends for their rewards.
