The defense problem of the star field has always plagued mankind, low-level enemies are fine, if they encounter an attack by a high-level enemy, such as a high-level army composed of several dragon generals, then the human race will completely lose its depth, and completely lose the difference between the front line and the rear. Don't say it's impossible, as the war escalates, the contact between humans and aliens is becoming more and more comprehensive, and it is definitely a terrible nightmare for humans to concentrate high-level combat units.

A high-level unit with spatial teleportation capabilities can turn any star field into a battlefield in an instant, leaving you with no chance to prepare.

Humans are different from the dragonmen and the ghosts, each of these two powerful races is a natural weapon of war, they are usually either evolving or fighting, and they do not need any time to arm and can be ready to fight. Human beings have too many weaknesses, no matter how strong the whole is, the human society in the rear is a weak link, human beings are usually unarmed, and even if they are armed humans, it is impossible to carry equipment with them at any time.

If a group of dragons would bypass the front line where the human forces were assembled and directly hit the human settlements and industrial stars, the losses would be extremely terrible, and it would be almost impossible to solve! With the mobility of the dragon general, you can completely avoid contact with the main force of the human race, destroy your rear residents, destroy your factory, and the human troops can only wait for death, unable to catch up and fight, and watch their own strength weakened.

Even if civilians are not attacked, a surprise attack on a military base is no match for humans.

In other words, it is different, if humans raid the territory of the dragon people, regardless of whether the dragon people troops are assembled or not, their individuals can fight at any time, and their combat effectiveness is so strong at any time, and the humans have the advantage of raiding but can take advantage of it.

Therefore, the establishment of an effective defense and early warning system is imminent, without which humanity will lose.

You don't need to go out of the ninth order, who made your weakness so obvious.

After discussions among the commanders at all levels of the Tianchen, the preliminary requirements were reached. A defense early warning system must have the following elements:

First, it is necessary to have a space teleportation function that denies the enemy, so that the enemy cannot directly open the passage to his rear.

Second, it is necessary to have sufficient early warning capabilities to prepare human forces in advance.

Third, it is necessary to ensure that the information in the system is smooth at all times, so that each combat unit knows where the enemy is and what he is doing at the moment, and cooperate with the space bridge system to transmit troops to the past at any time.

Fourth, it is necessary to realize unified command and deployment in the large star field. Efficient use of war resources.

Fifth, limited offensive and defensive capabilities. This system includes the planet's large fire shield system, preferably with the ability to quickly counterattack, as well as the ability to confuse and deceive the enemy, even with limited counterattacks, which can slow down the enemy's attack and wait for the main force to be assembled.

A total of five basic characteristics constitute the defense network of mankind, which is the prototype of the great "theater defense system" of mankind in later generations. It is the first step in a new mode of defense for humanity. Only by truly achieving these five points can we avoid exposing the weak links of mankind to the enemy's attack, allowing mankind to have more initiative in the strategic posture and arming mankind as a whole. It can really wrestle with other races in the Tianhe system.

The five points have been unanimously agreed by everyone, but it is not easy to achieve these five points.

The fifth point is extremely resource-intensive, and the entire defense system will inevitably be dispersed to all parts of the star field to form a network. This creates a dispersion of power, so you can't invest too much. This is just an early warning defense system, not the main force. The dispersion of forces is also a taboo for soldiers, so the power amplifier capacity of the system is also limited, aiming to create trouble for the enemy and drag them down.

The fourth point is best realized, it should be said that it has been realized now, this is the command system that Qin Guan used at the beginning, the distance of information across space is instantaneous, and now even materials can be transmitted at any time, not to mention information.

The third point is the construction of huge consumption, of course, the start of the space bridge system is an emergency, and it is more economical to fly directly in normal times.

The second point is a big trouble, human beings can't effectively warn now, as soon as the space channel is opened, alien troops will continue to open out, how long can you warn in advance? It is best to sense where the enemy is about to open a passage, then you can gather troops as soon as possible and wait at the exit, and kill as many as you come, which is the most advantageous situation, and if it can be achieved, it will also force the enemy to dare not get too close to the human defense zone to teleport troops.

The first point is the most difficult, space is not yours, the energy field theory tells people that space belongs to all cosmic objects, and you can't stop people from teleporting to somewhere, as long as they are still part of the universe, they can teleport to the past.

The second and first points have not been achieved by human beings, and human technology has not yet reached this point.

However, that was all in the past, and Qin Guan's discovery gave mankind a new understanding of space.

If you want to achieve breakthrough technological development, you have to rely on the research power of the Tianchen Star Domain, and the technology of Zhongzhou Star Domain is not good, although the concept of the crit cannon was proposed by Qin Guan, but the specific realization has to rely on the research and development team of the Tianchen Star Domain. In order to seize the time, Qin Guan asked the team from the Tianchen Star Domain to come directly and start the research and development work on the industrial star in the Zhongzhou Star Domain, and the facilities on the industrial star were almost replaced by them.

In peacetime, such a large project would have taken a long time.

First of all, it will take a few years to demonstrate, instead of a few officers making requests and starting work directly, you have to argue whether each part is possible to achieve, and whether it is necessary to meet such requirements, as well as the cost of the whole project, and the transfer of so many resources will not affect the people's livelihood project?

Countless sub-projects have to be argued one by one, and sometimes a single detail can be stuck for years.

Then there is the test part of each subsystem, after the test is successful, the whole project can be carried out, this test is not very fast, even if you succeed in the test, you have to repeat the test many times to prove the reliability.

The next step is the initial architecture of the whole system, such a huge system, generally due to reliability problems or feasibility problems, some subsystems will be cut, and then due to resource problems, some of the subsystems will be cut...... Eventually, we will have a simplified, cost-effective operating system, and then we will start a trial run for several years, intermittently due to the lack of resource allocation......

But now is wartime, and everything comes first to the needs of war.

Unreliable? That's not a problem, even if it's wasted, no matter how many people die, you have to get it out first. It's enough to make a difference once.

The development and construction were carried out almost simultaneously, and Qin Guan's requirements were to get it as fast as possible.

One by one, the space station began to be built on the industrial star, which is the basic node unit of the theater defense system, and the content in it was very simple at the beginning, the Sky Eye system, which is mature, and the fire cover system must have the ability to connect in parallel with adjacent nodes to carry out common defense.

Space teleportation station to deliver information and supplies. Or even the main force of humanity.

Energy field jamming systems and weapon systems, which will have to wait until the rest is done to see how many resources are left.

Space shielding system, which is a completely new technology.

Coupled with the energy and material reserve and supply system, and the platform system connecting the battle trains, this is the eight major parts of the theater defense system, and the basic function of a node space station. It may seem like there are too many functions, and a space station can't be built too big, but in fact, every function doesn't have to be too powerful, such as teleportation. The distance does not need to be very far, such as weapons, and it is not used much, and there is also the ability to transmit information. If you deploy more, you will have a relay transmission effect, so you don't need to be too strong.

But the early warning function must be strong, and all that is done is to buy time for the human forces.

"The number of deployments on the periphery of the star field is relatively large, so there is no need to install weapon systems. As long as the eye of the sky is strong enough, and the space station deployed in the core area needs to strengthen its defense capabilities, as well as the level of the fire cover. "Qin Guan controls the rhythm of the entire project. In order to save the consumption of resources, "the outer space stations are far away from each other, and the detection range is too large, so they must be equipped with a sufficient number of automatic detectors, to put it bluntly, it is just a larger electronic dog." ”

So the people involved in the project came together, including the person in charge of production.

"So the specifications of the node space station are not exactly the same?" The person in charge of production nodded in understanding.

The person in charge of the Space Research Institute of the Academy of Sciences of the Tianchen Star Domain said: "There is still one thing missing, that is, the space shielding system, the physical object we made is not big, but the effect is not very satisfactory, at least it cannot reach the ability to prevent the other party from teleporting in space, and can only interfere." ”

Qin Guan asked, "Can you find out in advance?" Can interference delay the other party's teleportation? ”

The person in charge of the space office nodded: "Yes, but ...... There is still a lot of room for improvement. ”

The fact that there is a lot of room for improvement means that it is not satisfactory yet, which is difficult enough for researchers, who are still exposed to this kind of field for the first time. Regarding the spatial shielding, Qin Guan only discovered this phenomenon, both the Taoyuan Star and the Netherworld Emperor have this ability, but the Taoyuan Star Domain is the entire space is shielded, resulting in absolute spatial isolation, and the Netherworld Emperor just isolates himself.

The space shielding realized by the space is just a kind of interference, preventing the formation of the other party's channel, which is different from the shielding phenomenon that has been formed in the Taoyuan Star Field, the interference of human beings needs to pay energy, and no amount of resources is enough if it is turned on all the time.

Qin Guan was a little dissatisfied: "Continue to work harder, the goal is to try to advance the time of early warning." ”

The High Energy Research Institute is responsible for the fire cover system, and they also have difficulties: "Our current fire cover system can only achieve the parallel connection of three nodes, and it can't protect a whole planet, do you think we can increase the output?" ”

It would not be cost-effective to increase the output, Qin Guan shook his head: "If the output is increased, there is no point, my eight-star armor can achieve the output of protecting the entire planet, but if we do this, it will be equivalent to fixing an eight-star armor on the planet, is the eight-star armor so easy to manufacture?" This means that we spend a lot of resources, but the efficiency of use is greatly reduced, and our ultimate goal is not defense, but offense! ”

The person in charge hesitated: "Then we will try to increase the number of parallel connections, but it is difficult to do it in the short term, if there are many parallel connections, we need to reduce the output, which will not stop most attacks." ”

Qin Guan could only settle: "Then lower, don't expect to be too effective, just create trouble for the other party, at most, let the human buildings on the surface of the planet have stronger protection capabilities, and everyone is equipped with battle armor." ”

……

Just as the human race was desperately arming itself for battle, the higher-ups of the other two races were also shaking.

Wraiths, the core area of the star field.

"Lord, one of our war zones has been breached by humans, and the news we brought back is ...... The key was obtained by humans. ”

"What, who is carrying the key...... As I recall, that star field didn't seem far away. ”

"It's not far. It seems that the human race has the combat power of the ninth order. ”

"Can it be so fast? When they were defeated, they didn't even reach the strength of the Eighth Order...... By my order, all the royal families were gathered together, and our two royal warriors were missing, this matter is not so simple, it must be treated with caution! ”

Soon, the peak combat power of the Ghost Clan gathered, and they were all super energy bodies.

Generally speaking, these super energy bodies are not directly involved in the actual battle, they have to balance the ninth-order units of the dragon race, and if it is the turn of these peak combat power in the universe, they will directly face each other. No one wants to see the consequences.

"Lord, is this true?"

"It's impossible, with the fragility of human beings, they will definitely not reach the ninth order, and they will not be willing to change their form of existence."

"Even if they could, they couldn't be so fast!"

The ninth-order Nether Emperors couldn't believe in this kind of thing, did the human race want to ascend to the sky in one step?

In fact, their guess was correct, Qin Guan didn't really reach the strength of the ninth order, it was just a chance accident that allowed him to limit the Netherworld Emperor's ability. And what he's doing now is maximizing the benefits of this accident. No matter how bad it is, it will have to deal an effective blow to the high-end combat power of the ghost clan, and in the future, it will not dare to move lightly in the face of the human offensive.

The Lord spoke: "I don't think it's possible, it should be that humans have mastered some special means, they can create powerful tools to achieve their goals. Now that the facts are in front of us, isn't it worth taking seriously? ”

"The Venerable Lord is right, this is at least a potential crisis, which can threaten the existence of the ninth order. This is not to be underestimated. ”

"Leave it to me, I'll take a look."

"I don't agree, our two ninth-orders have been planted there. Stronger forces should be concentrated to wipe out humanity! ”

The Nether Emperors quarreled, in fact, they were not idle, they were both at the level of the ninth order, and there was still a difference between strength and weakness, and the job of the ninth-order unit was to strengthen themselves at all times and maintain their strength to continue to increase. Therefore, they have reached the point of the ninth order, and they are still constantly seeking breakthroughs, and the existence of the ninth order is combat power, but if it is stronger, it will gain greater initiative.

casually attracted all the attention of a small human, so why do you have to do with the dragonmen?

The Netherworld Emperor Lord made a final decision: "Don't say it again, it's certain that this matter must be clarified, there must be some secret that the human race is hiding from us, this must be clarified, and the key must be taken back, everyone knows how important that is, right?" So I decided to send the royal family over again, the number is ten, and I must find out what the situation of the human race is, and I am not afraid that they are strong, but I am afraid that we will not know. ”

……

At this time, Pang Heli had returned to the core area of the dragon race, facing a terrifying creature.

Even if they were battlefield commanders, powerful beings who could wipe out a large army in the blink of an eye, they were deeply terrified at this moment. That's right, the dragon people also know fear, but death can't make them afraid, and humans are even less qualified to make them afraid, and only the most peak combat power of the dragon people can make them fear-the Dragon Emperor!

The two dragons were firmly frozen in the space, and neither of them dared to make much movement.

Even if they were far apart, they could clearly feel that kind of power, which was the power of the pinnacle of the universe, and no matter dared to challenge it. If you get closer to a certain distance, no matter or energy can escape, it is the area of death, Pang and Li are very clear, and further on, it is the critical distance.

Now the two of them couldn't even see the light, and the cosmic energy field was constantly moving closer to the center of that terrifying being.

"You say that the keys and the black box are in the hands of humans?" The message came from the thick fluctuations.

"Yes, that human, he directly snatched the key from the ninth-order ghost clan." Pang replied cautiously.

"When did humanity have such a means? Well, this is our good chance, and it's much easier to take it from the humans than from the Wraiths. ”

Pang cautiously suggested: "I'm afraid it's not that simple, the Ghost Clan will definitely send the royal family over." ”

The Dragon Emperor said: "Yes, but the situation has been disrupted by the human race, as a high-end deterrent equal to the Nether Emperor, of course we have to go over and take a look, you two, although you have brought back useful news, but it can't hide the fact that you have failed!" ”

Li hurriedly said: "We didn't expect that the human race also has an eighth-order warrior. ”

The Dragon Emperor said: "Then you lost three against one, and one of them was killed, how to explain it?" ”

How to explain it? In fact, Qin Guan didn't win, and there was a sneak attack on the Tianchen, they just fell into the space trap together, but is it interesting to defend like this in front of the Venerable Lord? Pang could only obey: "That's our fault, and we are willing to accept the punishment of the lord." ”

"There is no need for punishment, you have to atone for your sins and go to the battlefield of the Ghost Clan."

"Yes."

The two dragons retreated, and the Dragon Emperor sent another powerful message: "It seems that we must face up to the human race, human ...... A symbol of weakness, I didn't expect them to be able to walk back, so what are we...... Order, the royal family assembles, go to the coordinate star field, your task is to fight for the black box and key, be careful of the humans, but also be careful of our old opponents, they will definitely send a lot of the royal family over. (To be continued......)
