At the moment when the final breakthrough was completed, the project team in Xingfeng Science and Technology City received the calculation results at the same time.

Fifteen minutes later, the design work of the last component was completed.

The atomic-level laboratory lathe started immediately and quickly put into trial production of components.

Half an hour later, the first half-ton single-body overclocked short sound player came out.

This is a square iron box with a side length of 0.5 meters and an extremely complex internal structure.

Three days later, about 100 kilometers outside the orbit of Pluto, a small battleship was parked here.

On the battleship stood Chen Feng, Tang Tianxin and several other senior officers of the United Government Army.

However, an expressionless square-faced soldier stood at the front of the crowd, looking at the distant deep space with empty eyes.

Under the magnification of the ultra-high-power optical telescope, a large square box with a side length of one meter was floating quietly.

In the box was a prototype ultra-high frequency short sound player and a deck of tarot cards belonging to the square-faced sergeant.

Most people focused their eyes on Chen Feng's face, waiting for his order to start the test.

According to the original plan, as soon as Chen Feng gave the order, the square-faced sergeant would raise his finger and press the virtual button in front of him.

Two and a half seconds later, 700,000 kilometers away, the receiver on the outer shell of the large square iron box would receive the gravitational wave signal and respond immediately. A

tiny direct current was generated from the receiver and transmitted into it through the wires embedded in the thick sound insulation layer.

This is a very traditional and ancient craft. The response speed is not fast, but the biggest advantage is that it is not easily interfered with and is stable and reliable enough.

The player inside receives the signal and responds, and will immediately play the short ultrasonic sound that Chen Feng intercepted in his mind.

The sound is not transmitted through the air vibration sound waves familiar to humans, but uses electromagnetic waves as a carrier.

Under the obstruction of the absolute sound insulation material of the outer box, this electromagnetic signal will only be confined to the box.

After another 0.3 seconds, according to Chen Feng, a terrible explosion will occur.

The absolute impact caused by the explosion will sweep a range of hundreds of kilometers in diameter, blasting this area into a near vacuum.

The secondary impact will spread to one thousand kilometers, tearing the experimental battleship on the edge to pieces.

The deadly aftershocks and super-strong radiation will spread out a killing range of more than 3,000 kilometers in diameter. Even the Eagle Strike Warriors, protected by armor, will be killed or injured.

On the surface, the power of this bomb is not completely beyond the imagination of the military and scientists, so when they first heard about the power of the particle bomb, they were not particularly frightened. After all, today's super-yield proton fission and force field tearing composite bombs can theoretically achieve such killing power.

But Chen Feng told them that it would cost nothing for the invaders to make a particle bomb, and it would not take time, and it could also cross the distance limit.

Moreover, the killing effect caused by this explosion cannot be described in words. It is definitely tens or hundreds of times stronger than the most powerful weapon currently used by mankind.

When the invaders reach the edge of the solar system, they will be able to ignore the limit of the speed of light and directly locate the consciousness of all human beings through the air. They will use human consciousness as a thought beacon and cross infinite distances to attach the particles to any cosmic dust particle in the solar system through the air.

No matter how small the particle is or how far away it is from the carrier of the thought beacon, it can be completed almost instantly.

This means that as many particle bombs as there are invaders, they can make them appear anywhere at any time and explode whenever they want.

5.7 billion people, 5.7 billion particle bombs, and even one bomb can be located on the top of each person's head. How terrible is that?

In fact, Chen Feng has never seen such a scene. He just made an inference based on the last situation.

When the invaders drop particle bombs through the solar system barrier in advance, they need to locate the heads of commander-level humans with more active thinking, stronger willpower, and more intense brain quantum storms.

But when their warships arrive in person and can perform higher-intensity and more subtle manipulation, then ordinary people will not be spared and will also become carriers for making bombs, and there is no need to locate them on a certain interest carrier.

The reason why Chen Feng dared to make such a conclusion was that in the previous timeline, when he was fighting alone until the last moment, the total amount of particles dropped by the invaders through the air had already exceeded the total number of members of the human commander sequence.

However, although humans have mastered the bomb now, they still cannot control it as finely as the invaders. They still need a carrier as a medium, and they cannot accurately detonate it at a fixed point. What

if a lot of them are prepared, and a handsome guy comes up and says, I'll set off a small firework to scare people, but the super-frequency short sound sweeps the whole space, and the earth is blown up in a flash.

So everyone came up with a solution, and they can only do it like now, with a single semi-closed system in a box.

In order to prevent the signal from being interfered with and unable to detonate during combat, the most stable gravitational wave signal is used as the carrier during remote control operation.

At the same time, the detonation authority cannot be left entirely in the hands of the command sequence, otherwise, if the signal is cut off during combat, it will still be a waste of effort.

That's why a cross-dual control system is used as it is now, which allows Chen Feng to give orders and the operators to execute, and the loaders corresponding to the particle bombs can make independent decisions.

"Let's start the test." Seeing that Chen Feng was silent for a long time, Tang Tianxin touched his shoulder lightly.

Chen Feng thought for a moment, "No more testing."

"Why?" Ou Qinglan was puzzled.

Chen Feng lowered his voice, "No reason, consider the test a success, immediately start to expand production capacity, select... 200,000 loaders."

After saying that, he waved his hand.

Not everything needs to be explained to the technicians, he just needs to know it.

Just now he suddenly realized that since the invaders five hundred years ago were able to temporarily change their strategy and give up playing "Song of the World" and instead release s bacteria, it means that the invaders have some means to simply scan the situation in the solar system.

If the bomb is detonated in advance, the invaders who will arrive in less than a month are likely to discover it in advance and take precautions.

The trump card of one's own side will lose the effect of unexpected king bomb.

But another possibility is not ruled out, that is, including the existence of the stars, the entire process of human research involving particles has been exposed.

If the other party's information control is really so accurate that even these top-secret data are known, then Chen Feng also said that there

is nothing he can do about it. What can I do? I can't just do nothing, right?

Give it a try, anyway, it won't hurt to guess wrong.

In the next twenty days, humans have accomplished several major things.

A fleet of 200,000 loader ships has been formed.

The selection process is carried out in secret, and the selected will be clearly informed that you will be played "Songs from the World Beyond" and will lose human emotions.

The entire selection process is entirely voluntary. Before making a decision, the selected are prohibited from communicating with each other, and people don't even know who around them has been selected.

Unfortunately, humans cannot control "Song of the World" to the same extent as invaders.

After comprehensive demonstration, the project team found that only members of the middle-level and above leadership sequence can catalyze special interest carriers after losing their emotions.

Taking into account the instability and potential harm of particle bombs, the combat sequence cannot lose all middle- and high-level commanders.

In the end, the three major committees discussed together, and Chen Feng made the final decision to select only middle-level and above commanders from the eagle fighters and shipboard soldiers, such as the captain of a medium-sized ship or the captain of a falcon squadron.

The selection targets start from the bottom of the comprehensive score ranking and work upwards.

If someone refuses, they will be automatically promoted until 200,000 people are selected.

There are more than 5 million people who have reached this level in the entire army.

At first, Chen Feng thought that at least 2 million people would have to be promoted to complete the selection.

After all, once you become a particle carrier, it means that you will almost lose all your emotions and perform the most dangerous mission with a chance of death. This is not a simple sacrifice.

But unexpectedly, the selection team completed the task just after asking 200,000 people. No one refused, and all agreed to change jobs on the spot, quietly leaving the combat sequence and joining the special warfare fleet composed of 50,000 small warships with specially enhanced power.

The special warfare fleet is directly commanded by Chen Feng himself.

Everyone in the fleet will receive targeted Eagle Strike Armor training, with a focus on strengthening mobility and charge capabilities.

Each person's Eagle Strike Armor is over-equipped with curvature engines, surpassing the five of the Sky Eagle and reaching six engines, second only to the Dragon Eagle.

Square particle bombs will be installed on 200,000 suicide beasts, corresponding one-to-one with the loaders to fight together.

There is only one goal, to form a suicide squad.

Those middle-level commanders who did not wait for the selection saw their colleagues who were ranked lower suddenly disappear. Although they would not ask too much, they could guess with their toes that these people went to perform secret missions, and they were envious.

In addition to the above work, the Science Committee and the Industry Committee also completed another thing.

In addition to the sequence of the coalition battle fleet, the giant space shipyard worked overtime and consumed all the remaining energy to produce an additional 5,000 giant transport ships, each of which can carry about 600,000 people. They are called Spark Giant Ships.

Each Spark Giant Ship is 13,600 meters long and has a bullet-shaped layout. It is equipped with a super-large curvature engine of the same level as the battle mother ship, a high-power and high-limit pressure-resistant medium engine, and the same advanced reverse magnetic and unified three-force shields and transmission force field shields.

When the power is fully opened and the speed is full, the Spark Giant Ship can achieve an acceleration capability that is one level higher than the battle mother ship. It is only slightly inferior in terms of turning and maneuvering, and the cruising range is as high as 300 light years.

In order to improve the acceleration capability as much as possible, the Spark Giant Ship was equipped with almost no large weapons except for the neutron shielding layer, and only light firepower equipment at the level of a medium-sized battleship.

In addition, each Spark Ship also has 100 small escape ships, each of which can accommodate 1,000 people, with a total range of 76 light years.

Some of the escape ships are loaded with frozen embryos ranging from 50,000 to 100,000.

Since then, mankind has completed all preparations.
