Now, Liu Qingshan knows that he must find a way to upgrade his combat unit!

Yes, in the face of the opponent's zombie mecha, it is so difficult to deal with yourself, so if it is against the opponent's more advanced combat unit, what will it be? The consequences will be unimaginable!

On the one hand, Liu Qingshan continued to produce Venom fighters. Yes, after all, judging from the current situation, the opponent's main means of attack is still mainly relying on that kind of zombie mecha. Fortunately, this kind of zombie mecha does not have air defense combat capabilities, so it will be helpless in the face of the attack of its own Venom fighter.

So, not long after, five more Venom fighters flew over! In this way, it will once again greatly strengthen the ability to protect the mines outside the base. Then, Liu Qingshan knew that as long as he could truly protect this place, then there would be no more problems in his economy. And after having economic security, then they will also be guaranteed in the research and development of new combat forces!

―――――――――――――――――――――――――

What has always made Liu Qingshan very depressed is that every time he builds a new base (which he must do in order to achieve a certain military purpose), he needs to re-study new combat units. And not the one-and-done one. Although this made Liu Qingshan very mad, there was no way to do it.

is still the same sentence, the other party did not create too much trouble for Liu Qingshan! That's the only thing that makes him feel better. Otherwise, I am afraid that the research and development of new weapons will also be significantly affected.

However, despite this, Liu Qingshan also knew that this also meant that the defense of the other party's base would definitely be very tight! It seems that the other party's strategy is already obvious, that is, to hold on! And in this case, the other side will definitely concentrate all its combat forces and tighten the battle line, so as to form a stronger combat effectiveness!

However, despite this, Liu Qingshan is also convinced that as long as he can have strong enough combat strength, then he is not afraid of even if he has a strong defense!

Now, Liu Qingshan is developing a beam cannon with long-range strike capabilities! This guy should be very good, he can shoot laser beams, although the lethality is not very strong, but the long-range strike ability it has is enough to make up for the lack of this aspect!

Moreover, this kind of beam cannon is most suitable for dealing with enemy mecha combat units, but the killing effect of infantry is not very good.

In addition, once the research is successful, then this also means that Liu Qingshan will not only have such a combat weapon, but also means that many combat units in his army will have such an attack method, including Venom fighters and even his own Scorpion tank! This is a great opportunity for your base to improve your combat capabilities!

―――――――――――――――――――――――――

However, just when Liu Qingshan was in full swing to build more military facilities and improve his comprehensive combat capability, the enemy army, which had not moved for a long time, finally moved this time!

A group of "black hand" infantry, looking like a group of ground monsters, and like a group of alien beetles, actually evaded Liu Qingshan's radar surveillance and had come to the edge of Liu Qingshan's base! When Liu Qingshan found out, they had already done it with one of their own armed teams stationed there!

"Huhu~~~" The enemy infantry named "Black Hand" actually continued to spray out a series of fire dragons, probably the weapon they used was a flamethrower or something, more than a dozen fire dragons, non-stop spraying out, criss-crossing, and soon, Liu Qingshan's dozens of armed squads were killed by a crying father and mother!

Fire attack is a very effective way to deal with infantry. Soon after, dozens of their own armed squads were wiped out!

Fortunately, at this time, Liu Qingshan had successfully built the "High-tech Research Room", so that some of his combat units, such as Venom fighters, raid four-wheel drive vehicles, and Tianqi tanks, etc., already had laser attack capabilities! Therefore, in this case, from your own base, from all directions, one after another laser beams are constantly ejected, and some laser beams criss-cross and interweave into a laser network!

Although, that kind of laser attack is mainly useful for mecha chariots, however, in the face of such a dense laser beam attack, the dozen or so black hands of the opponent are also difficult to resist! So, not long after, corpses were everywhere, and there was a lot of anger!

However, it was only at this time that Liu Qingshan realized that the group of enemy black hand infantry just now actually came from his "second mine"! This means that the military facilities you built there, including the ore refinery and outpost, may have been destroyed! After thinking of this, Liu Qingshan quickly changed the picture, and sure enough, there was a mess, and all his buildings had been destroyed!

After seeing this, Xiao Fan couldn't help but be furious! However, he knew that "the king should not be angry and raise a teacher". Let's bear with this breath for the time being, and wait until your strength is greatly enhanced, then it's not too late for you to take revenge!

"Damn, I've knocked out Lao Tzu's facilities, and Lao Tzu will build it again! There's one thing, fucking you, that's something that will never be destroyed, and that's Lao Tzu's will! Will! Will! Liu Qingshan thought firmly.

Half a minute later, another "Apostle" was produced. Then, Liu Qingshan called the aerial vehicle, and then once again airlifted the newly produced apostle to his (No. 2) ore collection site, that is, the blue Tiberon spar deposit that had just been discovered not long ago, and unfolded it!

Then, Liu Qingshan once again built his second ore refinery. And just after the ore refinery was built, out of it, a mining cart came out, which looked like a giant beetle. Then, on top of the blue Tibron spar deposit, it used its large, slender, paper-cut tentacles to collect the dark blue ore above the ground......

Subsequently, Liu Qingshan built his second heavy factory there. At the same time, more than a dozen stealth tanks and more than a dozen beam cannons in their own base also drove over together. In this case, it should be said that the troops stationed here are already quite strong. Yes, it is.

Liu Qingshan knew that since then, it was actually equivalent to expanding his sphere of influence again. Not only has its own resources expanded, but its base has been further guaranteed in terms of ore resources. At the same time, more importantly, because of the successful construction of a new base, the tentacles that led him to the core area of the Tiangu Mountains towards the enemy army have also become longer!

Yes, right now, Liu Qingshan is gradually getting closer to the core of the land of the Heavenly Valley! Liu Qingshan believes that one day, he will definitely infiltrate his own power there gradually! There, you'll build your own cutting tower, build your own laser tower, further secure your beachhead, and then, once you find an opportunity, you'll launch a Jedi counterattack!

Next, Liu Qingshan decided to send his seven Venom fighters to explore the way first! Yes, it's really necessary for yourself. Because now, it should be said, the conditions are ripe!

After a series of preparations not long ago, Liu Qingshan's hands have accumulated nearly 20,000 production and construction funds. You know, the nearly 20,000 production and construction funds, what that means, that's an obvious thing. The problem is that Liu Qingshan is not sitting on the empty side, but has a benign development! Yes, it's really a benign development!

In the base camp, although the ore mining has come to an end, the green Tyberon spar mine is still constantly crystallizing ore resources. In this way, it is certain that you can still collect a certain amount of ore resources from there.

And more importantly, on his No. 2 ore base, on the dark blue Tiberon deposit, his own collection has just begun! In this way, it can be said that I now, in terms of ore mining, there is basically no problem at all! It can even be said that its own economic operation has entered a normal track of benign development! Moreover, he already has enough combat strength to defend his base and defend his ore refinery!

Therefore, in this case, of course, it is necessary for me to send out the slightly inflated combat power that I already have! You must also send your own forces and your influence outward! Penetrate outward, radiate outward! Only in this way can you obtain greater benefits, and in order to finally achieve your military goals, force the other party to come to the negotiating table with you, and create conditions!

Peace, sometimes, that's how it is fought! And not begging!

Seven Venom fighters, all armed with laser weapons at this time, are flying over a dozen valleys. However, at this time, suddenly, Liu Qingshan saw that in the valley, a burst of smoke rose up, and it seemed that something was happening. Look closely, sure enough, wow, damn it! There......

A troop of enemy chariots is marching through that valley! Look at the upper branch, mighty, majestic, and imposing! Among them, three Flame Tanks, and three Mantis Tanks!

"You girl, Lao Tzu destroyed you!" After Liu Qingshan saw this, he gave an order, and the seven venom fighters rushed straight over. Yes, now, for Liu Qingshan, he wants to test what kind of combat ability his Venom fighter has after upgrading to a laser weapon! Now, such an opportunity has finally arrived! Haha, haha, it's finally here!

"Hit!" In this way, with Liu Qingshan's order, the seven Venom fighters brushed the ground together and began to attack the target! "Chirp~~~Chirp~~~" Dense laser beams shot out one after another, and the orange laser beams slashed across the sky, like lightsabers one by one, stabbing towards the target!

However, Liu Qingshan now finally admits that this kind of laser weapon is not as powerful as he imagined! The criss-crossing laser beams cut through the space, whistling and hitting the target one after another. However, for most of the day, I didn't kill a single one!

However, although the enemy's flame tanks do not have anti-air sniping capabilities, the mantis tanks that follow closely behind have very good anti-air combat capabilities! Whoosh, swish, several anti-aircraft missiles, flashing with dazzling white flashes, like meteors, crossed a white arc, and shot towards the target!

"Boom Boom~~~" This kind of missile fired by the enemy's mantis tank is really good, and the guidance ability is really good, and it is almost a miss! Not long after, Liu Qingshan's Venom fighter plane was shot down!

However, at this time, Liu Qingshan knew that he would never be able to retreat! Keep attacking! So, the remaining six Venom fighters continued to attack! Moreover, if the firepower is concentrated on one target and is not knocked out, it will not stop! The continuous laser beams hit it like lightsabers!

Finally, the enemy's flame tank, which could no longer bear it, finally exploded with a bang! And one of his Venom fighters has also been upgraded to one star! However, Liu Qingshan knew that it was useless to just upgrade to one star. In other words, the effect is quite small. Only after upgrading to the three-star elite level will it have a self-regeneration ability with quite good health! At that time, they can be regarded as "immortal eagles", and they are the pride of their own heaven!

What made Liu Qingshan a little incomprehensible was that under the fierce pursuit of his own Venom fighters, the enemy's chariots actually rushed towards his (No. 2) sub-base! After seeing this, Liu Qingshan almost shouted "Please enter the urn"! Yes, you know, there, you have deployed heavy troops! Hehe, I'm afraid you won't go there! In this way, destroying you, basically, is just around the corner!

Behind, risking the danger of still being slammed by the enemy's mantis tanks, Liu Qingshan's Venom fighters were still attacking desperately! In front, the opponent's flame tank had already started a fierce battle with its own stealth tank and beam tank that had been deployed there a long time ago!

"Huhuhu~~~" Clusters of fire dragon-like flames erupted out, looking like that, it looked like it could be burned away. At the same time, at this time, Liu Qingshan's seven or eight beam cannons finally showed their might!

"Chirp chirp~~~~" Orange beams of light, like a sharp sword, hit the target fiercely! So, a big battle was fought until the sky was dark, and the sun and moon were dark!

Now, it can be said that because Liu Qingshan has developed advanced combat weapons, almost all of his own combat vehicles have been equipped with laser weapons, and they are all capable of firing laser beams! And this kind of laser beam, it is certain that although it is not very powerful against infantry, if it is used against combat vehicles, it is their forte!

"Boom boom~~~" For a while, on Liu Qingshan's second base, the flames soared into the sky, and the explosions sounded one after another, and it has become a world of explosions and a sea of fire! The final result was that the opponent's chariots were naturally wiped out. However, Liu Qingshan's side also had at least three chariots that were seriously injured. Fortunately, Liu Qingshan has already built his own heavy factory at the second sub-base. And there, several unmanned maintenance aircraft are flying. As long as you rely on your damaged vehicle, then you can be sure that you will get the repair of the drone immediately, in a timely and effective manner!

So, next, Liu Qingshan quickly mobilized all his damaged chariots there. I saw that one drone after another, looking like a bumblebee, extremely sensitive, suddenly "stung" on the injured tank, and then started repairs!

"Zizi drowning~~~" A strange voice continued to sound, and with the sound of the sound of Zizi, the health of those damaged chariots was constantly recovering at a speed visible to the naked eye, and soon after, they were all restored to normal......

"Now, it seems, the time has come for a big attack! It seems that if Lao Tzu didn't really hurt him, the other party wouldn't really agree to himself so happily and come to the negotiating table! Now, with such a strong combat force of its own, it should be able to achieve its strategic goals! Liu Qingshan now felt that he could launch a real battle against the Heavenly Valley's Plain, the opponent's core base.
