I don’t know how many comprehensive shocks this has brought to the Lanzhou Military Region, but the largest this time has been the largest auxiliary corps of the military region, including the construction corps and the transportation corps, have been temporarily assigned to Han Zhen’s direct subordinates, and have fully participated in the transformation of the warm field. Fortunately, he has capable adjutants and secretary, as well as more than 100 coordinators who have recently joined the ninth department, which has prevented Han Zhen from being in a hurry.

In order to manage it, Han Zhen spent a lot of effort to move all the warm fields that need to be transformed to the vicinity of his farm, a place of more than 200 square kilometers, and built a military defense circle of the highest level of the military region. This is equivalent to the defense level of the headquarters. There are only three places in the entire military region that have such importance, but these three are not too big. Han Zhen scored 200 square kilometers in one stroke, which is the first in the military region. Peng Chong joked that he should move the headquarters here because it is safer here.

The good goods that the military region had accumulated for many years were taken out and the reserve warehouse was exhausted. The three old generals took the initiative and sold their faces to various military regions to ask for it. The military headquarters also went to the logistics department to advance the minerals and budgets for several years in advance. Even the three foreign countries also asked them to pay half of the minerals for the next five years in advance, not afraid that they would not want to. They have tested the advantages of Guanghan Rice, and after giving a little preferential treatment, they sent them in the shortest time... It is completely possible to say that all the methods that can be used were used, but in this way, they transformed 30,000 mu of fully enclosed temperature fields. Others moved there were 20,000 mu of ordinary temperature fields, which scattered all the large and medium-sized temperature fields in the entire military region.

Supporting defense facilities should be built within a range of 200 kilometers, and the troops and equipment that used to protect the temperature field were moved together, but this was far from reaching the highest defense level standard. Now the most important part of the Lanzhou Military Region is here. Peng Chong waved his pen and transported all kinds of weapons in stock. It was not enough. He transferred from other troops to dismantle what should be demolished and what should be reduced. Everything was renamed for the renamed Nine Science Agricultural Base! In this way, Nine Science Base became the most secure area with the entire military region.

When more than one million troops gathered together and tried their best to a goal, the results were huge. Han Zhen’s requirement for the base was to dig as deep as possible. After giving enough supplies and resources, the Construction Corps was really fierce in doing things. In a very short time, the 300 meters underground of this place could be said to have been dug through!

The upper part of the underground fortifications was reinforced and welded with military special steel plates, and the top was completely sealed with concrete mixed with special cement. It was like this when it was hundreds of meters deep, without any speculation. The reason why Han Zhen did this was to guard against the aerial strikes of the space fleet. It is no exaggeration to say that the fleet in the military region stopped in the sky and continued to bombard, and using all means, it would take at least six hours to lift the turtle shell that was several hundred meters thick.

Don’t think that opening this layer of protective objects is destroying the base! That is impossible. In a 200-kilometer-long place, Han Zhen built more than 70 temperature fields everywhere. Usually, it can be connected by passages, but after being hit, the measures to close the channel can be implemented. That is to say, destroying one place will not affect other places. Six hours or a few minutes is enough to close the channel. Therefore, if you want to completely destroy this base, you must plow the entire area of ​​more than 200 square kilometers one by one!

Of course, don’t think that you can attack the protective layer of the base so easily. Han Zhen spared no effort in the configuration of the base’s defense weapons, otherwise he would be the best name in the military region. Various anti-aircraft guns do not need to be concealed as before, and stand directly outside, with muzzles like chimneys of different sizes, which can make people shudder by looking at them.

China is now the most powerful. As long as it attacks a warship of the center arrow level, it is the most powerful air defense ultimate weapon, the cold fusion nuclear-energy cannon, which has eight gates erected in the base. In terms of power, this giant cannon light is even stronger than the laser cannon sold by aliens! But its size is too large and heavy, the launch time and charging time are very slow, and it cannot be used on warships, but it is used for air defense, and the effect is still good. The planet is the best carrier, and it does not have to worry about being unable to bear it like a warship, and it has unique deterrent power.

The cost of the giant cannon is very high. Just think about it. It is four hundred meters long and has a diameter of eight meters. Such a giant cannot know how many types and tons of ore are needed. In fact, this is not all the reason why it is expensive. If you want to erect the giant cannon, you must have a huge base and a support for support. The function of the base is very simple. For such a large cannon, it cannot be erected without a base. Moreover, it is extremely moving when it fires. The recoil is scary. Without a solid base, firing a cannon is equivalent to being self-contained.

Kill; bracket. In addition to assisting the mount to erect the giant cannon, the function of the bracket is to adjust the angle. The giant cannon that cannot rotate the angle is just a dead cannon, and it will not be afraid of the warship. Generally speaking, its rotation angle can be within twenty degrees directly in front of it. In other words, ten degrees can be adjusted in all directions around. This attack surface is actually not small. You must know that the target of the giant cannon is a high warship, extending ten degrees to the sky, which is a large attack area.

Giant cannons were defensive weapons made in the war years to prevent sneak attacks from enemy warships. They were popular when they were not as good as laser cannons. But now there are only fifteen doors in the entire Lanzhou Military Region, and eight doors were moved by Han Zhen, accounting for more than half. Han Zhen scattered these eight giant cannons around the base and ran in the sky with many small and medium-sized air defenses to form an air defense circle without dead corners. If you want to attack the base's body, you must face this terrifying air defense circle. For example, the space fleet in the Lanzhou Military Region, there is almost no possibility of breaking through this air defense circle.

Half of the cannon is under the ground, and even the base and bracket are hidden underground. It is a protective layer like a turtle shell, which maximizes safety. However, it is more than 200 meters above it, and it is still the eight highest among all the chimneys facing the sky.

Why is this giant cannon so small in number? The reason is that it is extremely time-consuming and expensive, which can be compared to buying a laser cannon from an alien. This is not the real reason for the small number. The real reason is that the giant cannon can only defend, and its use is too limited, and it is very clumsy to use - it is too heavy, it takes a long time to turn a scale. Naturally, the efficiency and accuracy of the attack are very low. In this way, after the laser cannon starts to be sold to the earth, it is better to buy a laser cannon from an alien. Move the laser cannon to the ground. Although it is less powerful, it is faster and more accurate, and there is no need to build such a troublesome base and bracket. In this way, it is clear who is better and who is worse.
