Now, Liu Qingshan knows that the shape is not optimistic for him. Yes, it is. As it stands, he has built two ore refineries in the base. Moreover, the two ore refineries were built on their own bases, and similarly, on land. However, with the two ore refineries, Liu Qingshan is not clear about whether they can build a good combat capacity production for their bases and provide sufficient funds for production and construction. However, as time went by, Liu Qingshan had become more and more aware in his heart that relying only on two ore refineries, it was far from enough.

So far, Liu Qingshan has seen that there are less than 2,000 production and construction funds left in his hands. However, for himself, the two most important military facilities have not yet been built. One is its own superweapon, a vacuum implosion bomb. The other one, that is, its own kind of Iron Curtain device. It can be said that these two types of military facilities are indeed quite important to oneself.

It can be said that, judging from a certain point of view, whether or not these two military facilities can be built in a timely manner will affect almost the entire operation and operational plan of oneself. It can be said that the vacuum implosion bomb, the superweapon of his own, is one of the most effective combat forces that can restrain the development of the enemy's entire base. In particular, sometimes, in certain circumstances, for example, in the face of the enemy's superfortress attack, when we do not have sufficient and more effective plans, we use this kind of vacuum implosion bomb to attack the enemy's super fortress, and our own super weapon -- vacuum implosion bomb -- is one of the most effective combat forces that can restrain the development of the enemy's entire base. In particular, sometimes, in a certain situation, for example, in the face of an enemy superfortress attack, when you do not have enough and more effective good solutions, it is a very good way to use this vacuum implosion bomb to attack the enemy's super fortress.

And that kind of iron curtain device, so to speak, is more useful in many cases. For example, once the enemy's base has built the enemy's superweapon, the Ao Chao Wave Energy Destruction Device, in this case, if you don't use this Iron Curtain device, then with the super strong defense capability in the enemy base and your own ground combat force, it is simply impossible to successfully destroy the enemy's super weapon, the Super Wave Energy Destruction Device. You must know that in order to defend against your own super wave energy destruction device, on the enemy side, it must also be three layers in the protective area, and the defense is quite tight, and those who defend that super wave energy destruction device are the elite of the enemy army.

Therefore, in this case, generally speaking, as long as you will be too strong in the past ground combat forces, such as the Apocalypse Tank, or the kind of magnetic explosion tank, at the appropriate time, they will be blessed with the Iron Curtain device, then, once the Iron Curtain Device is blessed, at least, within nearly half a minute, this kind of combat vehicle that has been blessed with the Iron Curtain Device is almost invulnerable, and they will not be knocked out of their health points at any time if the enemy attackes. Moreover, their ability to attack has not been affected at all. Therefore, after carrying the Iron Curtain device on his back, his own chariot concentrated his firepower and destroyed a super weapon in the enemy base in one fell swoop, which became one of the common means for Liu Qingshan to attack the super weapon in the enemy base.

－－－－－－－－－－－－－

Of course, in the current situation, no matter what happens, Liu Qingshan can't forget about the construction of his own air defense system. Yes, even when the base is first built, if you do not have enough anti-aircraft firepower, then once the enemy's air strike force arrives, you will have an overwhelming advantage over your own base, the military facilities and combat forces in your base. Therefore, its own air defense system must be perfected.

Under the current circumstances, Wu Liu Qingshan decided to build two anti-aircraft guns first. The two anti-aircraft guns were built on both sides of the holes in their base. One on the left, again. One. In this case, no matter which direction the enemy's air strike forces came from, they would be attacked by their own anti-aircraft fire.

In addition, Liu Qingshan, of course, has to produce some of the most basic ground combat forces. So far, Liu Qingshan has trained thirteen mobilized soldiers, produced four sickle mechas, and four bullfrog vehicles, which are in the process of being produced. At the same time, his superweapon, the vacuum implosion bomb, and the other superweapon, the Iron Curtain, are also in the process of being built. It is estimated that in about a minute, these two most basic superweapons of their own will take shape. It is in the process of being produced. At the same time, his superweapon, the vacuum implosion bomb, and the other superweapon, the Iron Curtain, are also in the process of being built. It is estimated that in about a minute, these two most basic superweapons of their own will take shape.

However, at this moment, just as Liu Qingshan was about to continue to build his base and produce more combat units, suddenly, there was one whistling sound after another in the air. With his rich combat experience, Liu Qingshan knew that it must be the enemy's air strike force -- the enemy's most basic and important air strike force, the fighter called the Tengu mecha, that began to attack his base.

At this time, Liu Qingshan couldn't help but feel a little relieved by his foresight just now. Yes, it is. If you hadn't built your own anti-aircraft guns not long ago, then in the face of the enemy's attack on this kind of Tengu mecha, it is likely that you would have fallen into a very passive situation. Now, just when the enemy's two Tengu mecha fighters were preparing to launch an air attack on their base, tom

Coax, coax, just like that, as those successive shells hit the target, in mid-air, Liu Qingshan clearly saw that a group of dark red explosion flames that caught the explosion were constantly shining and shining. The Tengu mecha fighter of the enemy after being attacked, because its own health is not very high, so, with a bang, it was exploded on the spot in mid-air. The other, which was quickly seriously injured, dragged billowing black smoke, whimpered in mid-air, and rushed to the ground, and then the nose crashed into a hill, and was blown into countless wreckage and debris, scattered in all directions, and landed on the ground from mid-air one after another.

Immediately afterwards, not long after, two helicopter gunships came over for the enemy's army, but in the face of Liu Qingshan's two anti-aircraft artillery fire, they were also shot down one after another, rushed to the ground, and were blown up with one or two dark red explosions. However, after that, for as long as five minutes, the enemy's attack was silent. It seems that in the face of their own defense, the enemy army is also thinking about it, and it is not possible to rush lightly, but to choose the right time.

For Liu Qingshan, this period of time is also a very favorable time for him to build a base and produce combat power. In particular, it was in a few minutes that the user finally built his two superweapons, a ten-vacuum implosion bomb, and a defensive iron curtain device. Now, his two superweapons are no longer counting down. Liu Qingshan knew that in about five minutes, his two super weapons would be ready for use. After thinking of this, Liu Qingshan's heart couldn't help but feel very excited. It seems that this time, there is hope for his victory. There is no longer a countdown. Liu Qingshan knew that in about five minutes, his two super weapons would be ready for use. After thinking of this, Liu Qingshan's heart couldn't help but feel very excited. It seems that this time, there is hope for his victory.

However, what made Liu Qingshan also worried was that not long after his superweapon was built, Liu Qingshan discovered that the enemy's superweapon, the Super Wave Energy Destruction Device, had also been built.

Yes, it is. Because of this superweapon, it's all open. In other words, once the superweapon in that area is built, then both sides will know where they are. This is also known as the openness of superweapons. Of course, Liu Qingshan also knows that the reason why there is such a rule is to make both sides prepared, otherwise, once this superweapon attacks by surprise, then, it is very likely that the balance of the war will be lost.

However, even so, once he saw the enemy's super weapon, the Super Wave Energy Destruction Device, and really built it, Liu Qingshan's heart naturally felt very uncomfortable. Yes, if you sit on pins and needles, you are restless, and there is a kind of block in your heart, which always lingers and is difficult to let go. Therefore, in this case, Liu Qingshan couldn't help but hate, no matter what, he had to find a way to destroy the enemy's super weapon first, the Super Wave Energy Destruction Device. Otherwise, it can be said that you will never be at peace. Moreover, I will always be passive. Of course, it is very disadvantageous for yourself.

However, Liu Qingshan also knew that it would not be easy for him to destroy the super weapon in the enemy's base, the Super Wave Energy Destruction Device. Judging from the current situation, the best way is to destroy Tongguò's own magnetic explosion tank, or the Apocalypse tank, under the cover of the Iron Curtain device.

Although Liu Qingshan also knew that if he had his own super-powerful attack force, the Conqueror battleship, and cooperated with his own MiG fighter to attack the enemy's super weapon, the Super Wave Energy Destruction Device, it was very likely that the effect would be even better. However, no matter what, so far, he doesn't have that kind of conqueror ship. Moreover, its own shipyard has not yet been built, so how can it produce conqueror warships in this situation?

In fact, Liu Qingshan knows very well in his heart that the situation he is facing now is the old problem and the old difficulty, that is, the production and construction funds are relatively difficult. It is more embarrassing, even overstretched, and very arduous. Therefore, the primary problem to be solved at present is to solve the problem of lack of production and construction funds in their own bases.

However, the only way to solve this problem is to build more ore refineries. However, Liu Qingshan also knew that if he wanted to build a few more ore refineries, then his sphere of influence must be extended to the place where the two ore veins are located. Otherwise, it would be impossible to build an ore refinery by yourself.

That is to say, only if your sphere of influence affects the place where the foreign country is located, then you can go to the combat unit at the ore vein, to be exact, next to the ore vein, and then build the ore refinery. In order to achieve this goal, on the one hand, Liu Qingshan did not forget to strengthen the defense construction of his base, especially the air defense. Therefore, after thinking of this, Liu Qingshan added two more bullfrog vehicle production plans. In this way, the anti-aircraft firepower of the six Bullfrog vehicles, combined with two anti-aircraft guns, it should be said that among their own bases, the air defense force is still good.

After thinking of this, with Liu Qingshan's order, the production plan of a survey vehicle was included in the production list. Although, Liu Qingshan also knows, that is, if you use that kind of base car, it will be better. Yes, after the production of the base car, the eight base car drove to the place where the ore vein was located, and the production plan of a survey car was included in the production list. Although, Liu Qingshan also knows, that is, if you use that kind of base car, it will be better. Yes, after the base car is produced, the eight base cars go to the place where the ore vein is located, and then it expands to become the main construction plant. Then, around that general construction plant, no matter what kind of military facilities you have, you can build them yourself.

However, this kind of reconnaissance vehicle has much less functions. However, the survey vehicle also has the advantages of the survey vehicle, that is, the cost is relatively low, the production speed is relatively fast, and it can be driven to the end of the vein in the shortest time. Therefore, after thinking about it again and again, under the situation of tight production and construction funds, Liu Qingshan still chose to produce the survey vehicle, and then, after reproducing the survey vehicle, transported the survey vehicle to the place where the ore vein was located, and expanded it into an outpost. In this way, you can build another ore refinery of your own near the vein. Then, after generating the survey vehicle, the survey vehicle was transported to the place where the ore vein was located, and it was expanded into an outpost. In this way, you can build another ore refinery of your own near the vein.

In this way, not long after, Liu Qingshan was excited to see that a survey car was finally produced. Immediately afterwards, with Liu Qingshan's order, his own reconnaissance vehicle set off from his own base, directly through the Guò water, and then, according to the author's own base, about 70 kilometers away, where a vein is located. Yes, Liu Qingshan just wanted to build his third ore refinery there. In this way, the more ore refineries are built, the more abundant the industry will be for the production and construction of its own base vehicles, and naturally, the more favorable it will be for the construction of its own base and the production of combat power.

Of course, in his own base, Liu Qingshan also did not give up the defense against the enemy's attack. Yes, under the current situation, since Liu Qingshan already has more than a dozen mobilized soldiers, there are still a few sickle mechas, and a few more are used by me. Therefore, the defense force in his own base, in general, is still good. In this case, Liu Qingshan's subordinates considered strengthening their ground defenses. Yes, not long ago, the enemy had launched an attack on his base, but that attack was an air attack. The two enemy Tengu mecha fighters were ruthlessly destroyed by their own anti-aircraft fire. After that, two more helicopter gunships, again destroyed by their own protective fire.

So, in this case, it should be said that the enemy will no longer use air power to attack his base. In this case, it is very likely that the enemy's ground attack will begin. Therefore, under such circumstances, it is naturally very normal for Liu Qingshan to strengthen the ground combat forces in his base.

Wu So, under such circumstances, Liu Qingshan put his more than a dozen mobilized soldiers on both sides of the entrance and exit of his base. In addition, behind them, there are two Scythe mechs that have just been produced.

In fact, Liu Qingshan is very aware of the possible ground attack of the enemy, that is, under the current situation, it is impossible for the enemy army to use large heavy combat forces, and generally speaking, some infantry combat units are used. Therefore, in this case, the several infantry combat forces in front of his stage, plus those scythe mechas, should be able to deal with the enemy's possible ground attack this time.
