Northern. The wall known as the lifeline is clinging to the shell, like a magnificent Wanjia maple harvest. Ten meters tall and six meters wide is a huge body. Make it an impregnable line of defense. It stretches from the Lion Ridge Mountains in the south to the waters of the Ming River in the north. With a total length of 78 kilometers, it took several years to mobilize a huge number of human forces to fight and complete the construction at the same time.

The existence of the lifeline also proves its value and is worthy of its construction price.

Before there was no lifeline, zombies were almost constantly pouring from the coast to the north of the inner 6, and the huge population of the coast led to a steady stream of zombies. They are endless, every day, every minute of the day. Gather people living in the north. Life is extremely hard, every day as long as the alarm comes, everyone will immediately move, and the people who live here, with two or three settlements, are almost spent in hide and seek with zombies.

With the strong rise of the generals, scattered settlements were merged, making it the largest settlement in the north.

If the only bad thing is. It is the force that belongs to the general, too close to the coast, the entire huge settlement, need to face a huge group of zombies every day, and need to pay a huge amount of human power to block, which also restricts the general's exhibition, so that he can only be trapped on one side, there is no problem in self-preservation, but he is unable to open up and annex other settlements.

In the face of fierce battles staged every day, the plan for the lifeline was proposed, and the construction began with huge human strength.

In the words of many people, it was a period of hard struggle, and hundreds of thousands of people threw themselves on it, using ants to build the city, and little by little the huge wall that was 15 meters high and six meters wide. In front of the building, hundreds of thousands of soldiers are fighting the zombies to prevent the zombies from hindering the construction of the wall.

The entire construction, under such conditions, was completed intermittently after three years of fighting and construction.

Thanks to the existence of the lifeline, the place where the entire settlement belongs is no longer plagued by zombies from the coast, and the people who live here live and work in peace and contentment, and all kinds of workshops and factories have risen one after another, and a large number of farms have been cultivated, so that everyone can have enough to eat, and there will be surplus food, and there is no need to worry about struggling on the hunger line all day long like the first three or four.

However, the attack of the zombies is still very fierce, every day is a wave of zombies hitting the wall, every day the battle continues, and violent gunfire will appear on the lifeline day and night. Occasionally, there is a pause, that is, when cleaning up the zombie corpses deposited below, and collecting the crystals one by one.

At the same time, the daily consumption of ammunition also seriously restricts the development of the settlement, and it is precisely in this way that the general, who is the ruler of the entire settlement, has been looking for another solution. The use of crystallized energy has entered his eyes, and the research in the past three years has finally broken through many difficulties.

In fact, the general is just a former position and respectful honorific title, and for a long time, everyone is used to being called a general, so let it be, after all, he also likes the honorific title of the general very much.

At this time, the general was leading the senior generals in the large and small settlements to appear at the head of the wall, and below was a surging group of zombies, as far as the eye could see. The 78 kilometers that were intercepted were full of zombies, numbering in the millions. They are constantly pounding against the walls, and from time to time there are layers of high stacks.

"General, there is news from the Ministry of Commerce and Trade that there has been a change in the Tianzhou Plain, and it has been annexed by a force called the Yuanqiang Chamber of Commerce, and the other party has a large number of fighters, and its strength is very strong." As the general's secretary, most of the news needs to pass through his hands, which can be said to be a very powerful position.

The general's brow furrowed, and he unconsciously glanced at the West.

Since the mystery of crystallization has been solved little by little, huge human resources have been invested, sometimes in order to get the required instrument components. The general even went so far as to send heavy troops to storm the city and take back what he needed from inside. You must know that the impact is on the city, and the number of people who can come back every time is definitely only one-third.

Paying such a heavy price is to be able to use crystallization in advance.

As for crystallization, the general understands that it will be a new form of energy, and as long as its mysteries are known to the world, everyone will go crazy for crystallization. It was the foresight of the former that made the general, no matter how hard it was, grit his teeth and take out a large number of weapons and ammunition and send a large number of caravans. Attack everywhere and exchange weapons and ammunition for crystals.

This strategy was very successful, and the massive crystallization gathered, plus the gains from killing the zombies themselves, dozens of mountain warehouses were piled up.

The Tianzhou Plain is a bit far from the north. However, it does not hinder the arrival of merchants, and with small passenger planes, merchants can be delivered to various places. The requirements for landing are similarly low. As long as there is an open secondary road, it is possible to land. It is this low requirement that allows caravans to reach the surviving areas of human activity. Carry out trade actions.

Now I heard that an important crystallization acquisition point was actually swallowed up by an unknown force, just think of the hundreds of thousands of people on the Tianzhou Plain. The general's heart ached. If there is no accident, his plan is to incorporate the Tianzhou Plain into his colony when the crystallization is successfully used, and he did not expect that someone would be one step ahead of him.

The mood of this news for the general. It seems to have some impact, but it is not big" For him, the important thing is that today the crystallization will be used in actual combat, and it will also usher in a new era for the crystallization. In this case, the fall of the Tianzhou Plain naturally had little impact on him.

From another point of view, the Tianzhou Plain is currently beyond the reach of the whip, and there are several large settlements in the north alone. If you haven't taken it into account in front of you, how can you have the energy to make a distant idea? For the general, the use of crystals can increase his strength by dozens of times, and he can sweep the entire north", and if he wants to obtain the huge population of the Tianzhou Plain at that time, he can just take it.

Thinking of this, the general became indifferent to this information, turned his head to look at Dr. Bai next to him, and said, "Dr. Bai." Next, it's up to you to set up your research. ”

Dr. Bai nodded excitedly. said: "General, after nearly four studies, isn't it for this moment? From knowing the use of crystals on the human body, to now, we have been studying for seven months before we can finally popularize the smooth use of crystallized energy. Yes, no one would have thought about the real use of crystallization. It will be the same" As far as we can be sure, from the harvest, we are always ahead of everyone. Yes, Dr. Bai has a reason to be proud, because his research results will definitely change the situation of human beings in front of zombies.

Human beings are too fragile in front of zombies, and even a slight cut of skin is fatal injury.

It's better in the open, but in the narrow places like city alleys, humans are no match for zombies at all, and in the corners where you don't pay attention, there are deadly zombies, their ability to lurk. can make you unaware.

It has also been proposed before that the soldiers will be like the soldiers of ancient times. Put armor on them and protect them from zombies.

But the soldiers of old; The armor they use is not called armor, but leather armor made of leather, which has limited protection. And the officers used. It is called armor, but its weight is very high, and it only protects important parts of the human body, such as arms, neck, head, and legs, and there is no way to protect it.

Maybe the wars of antiquity. Your hands and feet have been injured by weapons, and you may be able to kill the enemy again. But in the last days. As long as you are injured by zombies, even if Da Luo Jinxian comes down to earth, there is nothing you can do, there is only one way to die. In this case, the role of armor becomes very limited.

If you say that you will protect your body, this pair of steel armor will be more than fifty or sixty pounds. How can a soldier fight when he wears it? I'm afraid that all of a sudden, I will already be tired.

In the final analysis. It is the reason that the strength of the human race is not enough, which leads to the inability to use this steel armor that the zombies cannot break. Strength has become the most critical issue, and it is precisely the mystery of crystallization. It's about being able to improve the indices of humanity itself. such as strength", nervous responses, and so on.

The more color grades the crystals can provide, the greater the amount of energy they can provide. Stimulation for humans also

。

A third-level crystal, its energy, when released, will instantly make the human body produce an enhanced mutation behavior when it penetrates into the human body. This variation. Depending on the ability, it will produce different results. The first-level crystallization can provide the human body with three times the ability to increase, and the second-level crystallization is six times" so calculated, the increase of each level of crystallization is three times, and each level will be replaced.

According to this principle, the ninth-level crystallization can instantly increase the strength of a person by twenty-seven times, "But is this really the case?"

A large number of experiments allowed Dr. Bai to finally figure out that the use of crystals is not available to everyone. It has a critical point, and at the same time everyone has a bearing point, your physique and genes can only withstand three times the strength of the first-level crystal, if you forcibly use the second-level crystal, your body will not be able to bear it, there will be cracking pain and other phenomena, and even bleeding inside the cell. And if you forcibly use nine times the power of the third-level crystal, your fate will definitely be miserable, because the cells that cannot withstand it will burst under this force, and the whole body will explode with a "bang", and there will be no bones left.

Therefore, every soldier who uses crystals needs to be selected, and through the tester researched by Dr. Bai, it is necessary to determine what level of crystals this soldier can use, what is his bearing point, and what level of crystals can be forcibly used in times of crisis without being fatal.

At the same time, the energy level of the crystallization also represents the time that its energy can be squandered, not that if you intensify the crystallization energy, you can use it indefinitely, the energy will be temporal, and it will be consumed at the same time, like a consumable. Once the crystallized energy is depleted, it crumbles into a powder and becomes impossible to use.

This feature of crystallization. That's why the general went to great lengths to store crystals, because of its non-reusability.

As long as you have seen the combat power of the soldiers under the use of crystals, no one will not go crazy for crystals, and when the time comes, it is destined that human beings will fight because of crystals, and the true value of crystals will be infinitely upgraded. Not many people know the mystery of crystallization at present. The reserve of crystallization in the early stage has become extremely important, and whoever grasps the opportunity first will become active in the future, rather than passive.

The soldiers in this actual battle, a full thousand, were wearing the armor specially created for them in the settlement, protecting them all in the steel armor. Even the eyes, too, are protected by bulletproof glass, not to mention the attack, even the liquid of the jet monster can't enter it, and the design of the steel armor has long taken this into account.

A thousand soldiers dressed in battle armor stood majestically on the wall, weighing thirty kilograms, which did not seem heavy at first, but as long as it took a long time, it would make people feel like a thousand pounds. What's more, the weapon they use is not a gun, but a **** of a long woman's rice, weighing nearly ten kilograms",

At the helmets of these thousand soldiers, at the back of their heads, there is a large protrusion, a small excitator, which is fixed to the helmet, and you can see the crystallization of energy flowing inside. The physique of a thousand soldiers is all the strongest and can withstand the strengthening of second-level crystals, so these thousand soldiers who will be used in actual combat are all second-level crystals.

The exciter has several special teleportation tubes connected to the soldier's neck, and the energy is transmitted from the teleportation tube into the human body after being destroyed, so that the cells can absorb it, so as to achieve the purpose of strengthening.

Crystals can strengthen soldiers, but they also have a big drawback, that is, the energy of crystals is consumed. The enhancement effect will fade. This swelling and sudden emptiness will give the cells a buffer period that does not react, and this buffer period will make the person who uses the reinforcement very weak, and it will take at least half an hour to return to their normal state before they can use the crystals again.

At this time, the thousand soldiers who had been waiting for a long time all put their backhands on the back of their heads when Dr. Bai waved his hand, and gently pressed the start button.

The working principle of the exciter is to use the sound captured in the destroyer, record the sound on the exciter, and build a small horn inside, as long as the sound inside is started, through the echo pipe, the sound is added, so as to destroy the crystals inside and release the energy in the crystals. And the energy is estimated to be released. It will be injected into the soldiers' bodies, thus strengthening the recess.

Dr. Bai only used this kind of strengthening substance, but he couldn't figure out why these energies could have such a strengthening effect on the human body. The goal of his next research is to decipher these energy substances, and as long as the decryption is successful, the human race will no longer have to rely on the crystallization of the Zong of the Sect

When the crystallization is destroyed, there will always be a strong burst of light, and the exciter fixes the position of the crystal, which is originally made of glass, and under transparency, the strong light of the crystallization can be dispersed. It is in this way that a thousand soldiers are activated at the same time, and even during the day, a spectacular blue light can still be seen.

The blue crystal is a second-level crystal, it can strengthen the human body is six times, it is already a very strong ability, at least wave the 2 meters Yu knife in his hand, there will be no difficulty, and the thirty kilograms of steel armor on the body will be as light as clothes.

The use time of crystals is 10 minutes for the first level, and 5 minutes more for each level after that. The blue second-level crystals can be used by the soldiers for fifteen minutes.

With the release of crystallized energy, obviously, the soldiers shook their whole bodies, and then one by one they frantically jumped down from the fifteen-meter-high wall, and directly smashed into the dense group of zombies below. The powerful six-fold ability makes them invincible, and as soon as they enter the zombie group, the 2-meter-long **** in their hands dances wildly, splitting the zombies in a circle in half.

Protected by steel armor, the surging zombies try to attack them as much as possible, but they won't do any damage. A thousand soldiers, each of them is like a meat grinder, everywhere they go, the zombies are all swept into two sections, and they are killing and wounding in a large area like Zhou Yuanqiang's method.

Like the density of zombies under the wall, there are too many of them, and these six-fold strengthened soldiers, coupled with the sharpness of ****, often swept by a big whirlwind, can sweep more than a dozen zombies into two sections. I'm afraid that the lethality is far from being compared to guns, and under the strengthening of crystals, they have completely turned into war machines, constantly advancing and advancing "In a moment, a huge group of zombies was gnawed off by a thousand soldiers."

This result, which stunned a group of high-ranking generals, and the first appearance of the soldiers known as the Crystal Warriors, was too powerful.

Melee soldiers are still slashing zombies. And the crystallized warriors armed with guns were intensified one after another under the order of Dr. Bai. At the moment when they intensified, they raised their guns and shot at the zombies in the distance, and the zombies three or four hundred meters away were hit in the head one by one, and they fell down one by one.

Dr. Bai said proudly, "Crystallization improves not only strength, but also nerve responses and so on. An ordinary soldier, without a scope, can successfully hit the head of a zombie at 200 meters, and he can already be called a top sharpshooter. However, with the use of crystallization strengthening, it can hit the head of a zombie within three or four hundred meters. Don't underestimate the distance of three hundred meters, if the two armies fight, you will understand that the difference between three or four hundred meters of attack and two hundred meters of attack, because we can kill them, and their damage to us is limited. ”

Hearing Dr. Bai's explanation, everyone present was amazed, as generals leading troops to fight, of course they understood what it meant to have twice the attack range longer than the other party.

For example, in the battle between the ground forces and the ground forces, except for artillery, tanks and armored vehicles, the battle between soldiers and soldiers will generally be born within 200 meters, because human eyesight, without an auxiliary scope, the shooting accuracy within 200 meters is the best. If you go out of 200 meters, it is generally difficult to hit the target.

However, the Crystallized Warriors are different, they can hit targets up to 400 meters away, and if they are not zombies, they can even hit the bodies of hostile soldiers 500 meters away. Think about it, what kind of consequences are the two armies fighting, the soldiers on the other side are killed and wounded in large numbers, and on their own side, with the protection of steel armor, it can be said that there are almost zero casualties.

Maybe someone will say that the other side has tanks and armored vehicles, what should I do?

In the last days, the lack of supplies, coupled with the fact that the city is inhabited by a large number of zombies, a place with a large number of weapons and equipment such as a military base, and guarded by a military spirit, who will get a large amount of heavy weapons? Take a look at a few of the settlements next to it. At the same time, they have hundreds of thousands of troops, but the armored vehicles are not pitiful? Not even a single tank. In this case, what is there to worry about?

What's more, it is completely possible to look for some people with better genes who can withstand the enhancement of higher crystals. At that time, these people who have been strengthened by nine or twelve times the ability will be able to carry heavy machine guns and launch a terrifying metal storm, instead of heavy machine guns that can only be used stationarily, as is the case now.

With the improvement of their abilities, these crystal warriors who have been improved several times, a distance of several hundred meters, can be completed in a short time for their running degree, and in close quarters, like chopping vegetables, the opponent's soldiers will be cut all over the ground. With the protection of steel armor, they are not threatened by the other party's **** bullets, and they are definitely a terrifying existence.

When the time comes, the forces that have this kind of crystallized warfare soldier species will definitely use overwhelmingness to win a battle.

And to see the performance of the soldiers in actual combat. The general finally burst out laughing.

Yes, with the protection of steel armor, ordinary bullets cannot harm the soldiers, which is in disguise, this crystallized warrior has become a terrible class, although in terms of use, they will only have fifteen minutes. But many times, fifteen minutes is enough to change the whole. The tide of battle is turning.

And with crystallized warriors, military bases in the north can be captured. It will weaken the power of the military spirit, and the price paid will be much smaller. As long as the military base is captured, there are no heavy weapons and no fighters in their hands. Without tanks, the situation will change completely. When the time comes, it will no longer be a dream to want to rule the entire north, to rule the entire Big 6.

Like cities, it is completely possible to use crystallized warriors to attack, bring cities under their rule, and obtain huge supplies.

Thinking of this, the general became ambitious, looked at the fierce and fearless soldiers below, his eyes became fanatical, and said to Dr. Bai: "No matter how long it takes, no matter how difficult it is to make the agitator, equip all the soldiers with the agitator as soon as possible, I will form a corps of crystallized warriors to regain everything we humans have lost from the hands of zombies." ”

"The people present, who dares to divulge a little secret, will be killed

The old four chapters, begging everyone for a monthly pass. I hope that my efforts can be recognized by everyone, thank you! (To be continued)
