Chapter 452 Both Hands Must Be Strong

Dark energy radiation weapons!

At this moment, through the last remaining spaceship that Han Yang brought from the Milky Way, the weapons with a rating of about 5.7, through the precise manipulation of dark matter and dark energy, let them directly act on the visible material world, directly act on the body of each of the more than 3 million Zerg sub-bodies.

In an instant, under high temperature, high heat and high radiation, these numerous Zerg sub-bodies that were enough to exterminate a low-level civilization all died without any resistance.

The previous moment was still unstoppable, but at this moment, it was already peaceful and clear.

The crushing of low-tech creatures by high-level civilizations was fully reflected at this moment.

Unable to defend, unable to resist, and even unable to perceive, even dying without knowing why.

Han Yang was calm in his heart, as if he had completed a small task, and sent out a large army of robots step by step to collect the bodies of these Zerg sub-bodies.

There was only one iron mine at the base, and no other minerals were available. At this stage, Han Yang is temporarily unable to open up a new mineral base. At this moment, these Zerg corpses rich in various metal elements can just supply the next stage of construction.

Calculated as a Zerg sub-body with a mass of 1,000 kilograms, 3 million heads are 3 million tons. At least 400,000 tons of metal elements other than iron can be separated from them, which can be of great use.

"It's a pity that the spare parts and consumables of the dark energy radiation cannon are used up. I can't start it again before I recover to the fifth level of civilization."

And Han Yang knows one thing very clearly, that is, the Zerg mother body will definitely not give up.

Seeing that the enemy is too powerful, and thus afraid?

That's impossible. Han Yang suspects that the brains of this strange life form of Zerg have not developed to the extent that they can perceive the so-called fear.

Zerg sub-bodies can certainly show certain combat qualities, and even cooperate with each other tacitly, but this does not prevent them from having no brains. Everything that looks like wisdom is actually just their instincts, and has nothing to do with wisdom.

I have killed 3 million Zerg offspring. Next, the Zerg mother will certainly send several times more offspring to continue attacking me.

By then, I will have no dark energy radiation cannon to use.

"It doesn't matter."

Han Yang thought secretly: "At my current development speed, I will soon be able to build an electromagnetic cannon defense system of the second-level civilization stage. Then I will use the weapons of the second-level civilization to fight it."

While collecting Zerg offspring, Han Yang also built the most important factory at the fastest speed.

Zerg offspring decomposition factory.

A large number of Zerg offspring corpses were sent here. Here, they will go through a series of processes such as cutting, smelting, separation, purification, and smelting, and finally produce various industrial compounds and single metal elements. Everything is an assembly line operation, which is extremely convenient and fast.

On average, this factory can complete the decomposition of 1,000 Zerg offspring every day, and finally produce about 130 tons of gold, silver, copper, tin and other metals.

This is the production capacity when it was just launched. It is expected that within 10 days, with the expansion of many robots, the decomposition efficiency of this factory will reach about 50,000 heads per day. More than 6,000 tons of various metals will be produced, which is enough at least at the beginning of construction.

With the support of more than 3 million Zerg sub-body corpses, a total of millions of tons of metal minerals, and tens of millions of tons of iron ore continuously mined from the base underground, the scale of this base has begun to expand rapidly again.

At this moment, its total area has reached 12 square kilometers, with various factories standing in rows, and the number of different factories has reached more than 1,500, covering almost all categories of industry.

In addition, tall planting buildings and breeding buildings have also been built.

They are each about 80 meters high, divided into 40 floors, each floor has an area of ​​more than 1,000 square meters, and the total available planting or breeding area is as high as 30,000 square meters.

The extremely precious various crop seeds, animal embryos, etc. brought from the Milky Way began to develop in these two planting and breeding buildings.

At the beginning, because there were too few seeds, embryos and fertilized eggs, the two buildings seemed empty. But it didn't matter. Han Yang knew that he would soon have more seeds and embryos in his hands, and the two buildings would soon be full, and he would be able to harvest various biological products continuously.

The internal transportation tracks connecting different factories have also been built, with a total of more than 500 carriages running day and night under the leadership of 30 locomotives.

The total number of robots has also increased to about 750,000, and both functionality and stability have exceeded much more than before.

After all, the assembly process of the robot factory and the production process level of each parts supply factory are also constantly upgraded.

At this time, Han Yang began to build the most important factory.

Electromagnetic gun factory.

The electromagnetic gun of the second-level civilization level is of course very simple for Han Yang. But compared with the industrial foundation that Han Yang has at this moment, it still seems too difficult.

Because of this, Han Yang can only put its construction on the agenda after he has a certain industrial foundation at this moment.

At this moment, after continuous iteration, the parts produced by various parts suppliers have already achieved certain accuracy and qualified performance. Therefore, after completing the initial construction, the electromagnetic gun factory immediately produced a large number of electromagnetic guns of various models and performances.

A unified energy supply network was built for them. Han Yang deployed the first batch of 100 electromagnetic guns produced in the middle of the base, overlooking the base and ready to launch long-range strikes in any direction of the base at any time.

It should be pointed out that the first batch of electromagnetic guns built by Han Yang are all models dedicated to the atmosphere.

The gas in the atmosphere is dense, so the electromagnetic gun projectiles need to consider aerodynamics and require a special shape. At the same time, its speed cannot be too high, otherwise the friction with the air alone will be enough to burn itself out.

After comprehensive testing, Han Yang confirmed that the projectiles fired by this batch of electromagnetic guns can reach a maximum speed of 3 kilometers per second, and the firing rate can reach 10 rounds per second. It still has a high hit rate within a distance of 10 kilometers, and can also penetrate the shell of the Zerg sub-body.

Some sub-bodies with thicker shells may not be penetrated, but it doesn't matter, it's just a matter of firing a few more shots.

Later, Han Yang increased the number of electromagnetic guns to about 10,000, deployed around the base, and surrounded the entire base.

The number is enough for the time being, and Han Yang immediately turned to the development of space vehicles at the second-level civilization stage, that is, various aircraft, satellites, spacecraft, space-based electromagnetic guns, radar detection networks, early warning networks, etc.

As for nuclear weapons, they are even more indispensable.

Due to the lack of uranium and plutonium, atomic bombs are temporarily difficult to make. But it doesn't matter, making some hydrogen bombs is still a piece of cake.

With hydrogen bombs, Han Yang has the ability to overturn the table in extreme situations, and his own safety has an extra layer of protection.

At the same time, because of the sufficient supply of weapons, Han Yang can finally open a branch base and further expand his stall.

The mineral resources of this planet are relatively poor. If you mine from the surface, you can't actually mine too many resources. If you go deep underground, Han Yang does not have enough engineering capabilities for the time being.

Even if there is, mining is too troublesome and the output is limited.

This reality forced Han Yang to look at the huge Zerg mother body that covered the entire planet again.

The Zerg offspring it created were drilling in and out of the underground of this planet all day long, constantly mining various minerals deep underground on the planet...

"If you want to develop quickly and expand the scale of the base quickly, it is not enough to rely on my own collection. These Zergs cannot be let go."

Han Yang immediately decided on the overall development strategy of "collecting by yourself and separating Zerg offspring, both hands must be strong".

Calculating the time, it has been several months since the last Zerg offspring besieged him. The Zerg mother body should have planned the next siege...

Sure enough, just as Han Yang expected, several newly launched satellites detected that more than 10,000 large offspring were ejected from the mother body, like an interstellar transport ship, rushing towards Planet No. 1.

This large sub-body is hundreds of meters long. A rough estimate shows that a large sub-body can easily carry thousands of small combat sub-bodies.

So, with more than 10,000 large sub-bodies, the total number of combat sub-bodies should be more than 10 million.

In this way, after all of them are wiped out, the amount of various rare minerals that can be harvested will be at least 1.4 million tons...

This is a fortune that is enough to make Han Yang excited.

With so many minerals, it would take more than a year to collect them by himself even if he went all out!

Han Yang was full of fighting spirit and immediately prepared for battle.

About a month later, the large Zerg sub-body landed on the surface of the planet. The "hatch" on the abdomen opened, and a large number of strange-shaped, large and small sub-bodies rushed out like soldiers, covering the mountains and plains, like a tide, covering all the surface around Han Yang's No. 1 base.

The flying sub-bodies that tried to attack the base from the air covered the sky and the sun, even covering the light of the stars.

There are even self-propelled Zerg sub-bodies in space, attacking the satellites and spacecraft built by Han Yang!

As for the underground, it goes without saying. I don’t know how many Zergs have drilled into the ground and tried to attack the base through tunnels. The number is so large that even the surface of the earth is shaking.

The total number is more than Han Yang estimated, and the total number is estimated to be 12 million!

The attack started immediately.

Han Yang did not hesitate and immediately operated tens of thousands of electromagnetic cannons to start blocking.

Hydrogen bombs will not be used at this time. It is powerful, but it cannot be used precisely because of its great power. Otherwise, all the Zerg corpses will be vaporized, and where will they collect metal resources?

For a time, the surface of this planet with dense air was filled with deafening roars and strange hissing sounds of Zerg sub-bodies.

Countless electromagnetic cannon projectiles, like plowing the land, launched indiscriminate attacks on the surrounding areas of the base. Various new flying vehicles, helicopters, fixed-wing aircraft, space-based electromagnetic cannons, etc., roared together.

Even inside the base, Han Yang did not dare to take it lightly.

Although the surface of the base has been hardened with high strength, the Zerg sub-body should not be able to drill in, but everything is prepared for the worst. What if the Zerg really broke in?

Just as Han Yang expected, the Zerg actually punched a hole in the high-strength stratum, and dozens of Zergs came out with their fangs and claws bared.

Fortunately, Han Yang was well prepared and had sent robot warriors with portable electromagnetic guns to patrol the base, so that they could kill the Zerg sub-body as soon as it appeared, avoiding damage to the base.

This battle was so fierce that the sky was dark and the sun and moon were dim. The liquid in the bodies of the dead Zerg sub-body dyed the earth black, and the bodies of many Zerg sub-body piled up like a hill.

Although sufficient preparations were made before the war, Base No. 1 still suffered some damage.

Under the completely fearless impact of the surface Zerg, underground Zerg, and flying Zerg, some Zerg still rushed to the periphery of the base. As a result, some walls, some electromagnetic guns, and some machinery were directly damaged by the Zerg violence. Fortunately, Han Yang was well prepared and immediately used new equipment to top it up, so that the defense line was not broken.

At this moment, after more than ten days of siege, most of the more than 10 million Zergs that attacked this time were killed, and a few escaped.

Or, they were summoned by the mother worm. After all, they are not afraid.

Looking at the mountains and seas of Zerg corpses outside the base, Han Yang was full of joy.

"To develop the base, you still have to rely on you!"

Han Yang sighed and immediately sent a large army of robots to clean up the battlefield.

After a few months of pause, the Zerg sub-body decomposition factory in the base began to roar again.

While working hard to develop the base, Han Yang was looking forward to the next Zerg siege.

This is almost inevitable, it's just a matter of time.

The development of things is just as Han Yang expected. After more than two months of silence, satellite detection showed that a large number of large sub-bodies were ejected from the Zerg mother body again.

The number is as high as more than 100,000! This also means that the number of Zerg sub-bodies that came to besiege this time is at least more than 100 million!

"Very good!"

Han Yang was overjoyed.

We are not afraid of you coming, but we are afraid of you not coming! We are not afraid of you being numerous, the more the better!

After the large sub-body landed, a new siege began.

At this moment, the area of ​​Base No. 1 has expanded to about 100 square kilometers, and the number of electromagnetic guns deployed on the periphery has also increased to about 160,000.

Han Yang was originally confident and thought that this time it would still be a piece of cake. But as soon as the battle started, Han Yang was surprised.

He saw that the Zerg sub-body, which originally only used close combat and used its own sharp claws and teeth to attack, actually changed its fighting style at this moment.

They started firing projectiles! (End of this chapter)
