Tower Defense: From Stoneware To Interstellar, I'm Invincible

Chapter 103: Advancing to the Electrical Era, Birth of Anti-sky Technology (seeking flowers)

On the second day, Su Yu found that his points, which were already only a billion, had turned into more than 15 billion.

It’s only been one night, and in 24 hours it’s more than 20 billion, close to 300.

Only then did Su Yu feel that the higher the civilization, the faster and easier it is to earn points.

In the SSS mining area, Su Yu and his own army occupied the entire mining area.

It's just that they found that mining machines had been placed in those mine pits.

Although the size is the same as my own mining machine, there are some differences in appearance.

Difficult to be different models of mining machines?

Su Yu doesn't care about that much.

Directly order people to pull out all the original mining machines and leave them on the side, and use their own mining machines at night.

He is serious about earning points, and he needs points for everything in the future.

I also pursue speed, and the cost is even more severe.

After setting up all the mining machines, Su Yu glanced at the system.

[Current mining point income: 39 billion/day]

Okay, okay, that's great.

Su Yu now feels uncomfortable when he thinks that there is still a Sol on his head.

Fortunately, this guy can't protect himself at the moment, but 07 is that he can't always expect others to be trapped in the electrical age.

I should also improve my strength, in case of a fight, I can't suffer.

This man who was once known as the number one genius in the Black Eagle Country is somewhat mysterious.

Su Yu, who returned to the Dragon City, saw that he was still such a backward city defense.

Can't help shaking his head.

The comprehensive upgrade plan has officially started.

Because the scientific and technological research projects he set up have all yielded great results one after another.

My own development has reached a bottleneck in the steam age.

It seems that many theories proposed in the "Theory of Relativity" were not verified until more than 100 years later.

It is because in the era when it was proposed, the level of science and technology was not up to the height of verifying it.

At present, many science and technology have achieved theoretical success, but the basic science needs to reach a certain level to realize it.

[Ding! Your GDP is currently 49 billion points. Under the current productivity conditions, further growth has become slow, please host advanced electrical age. 】

All the conditions are met, especially the degree of civilization, because the birth of various scientific and technological achievements has exceeded a lot.

Let's get ready for work.

Su Yu first made all the city defenses of the Dragon Capital a concrete and steel structure.

The core area is heightened and reinforced, and the tens of meters thick concrete structure makes ordinary shells daunting.

This renovation project alone consumed 10 billion Su Yu points.

But it's all worth it.

The new city defense has 100,000 dark forts and 500,000 various defensive weapon platforms.

In other words, if Su Yu has any new weapons in the future, he can directly put them on these platforms, which will be a point of fire.

It is rumored that the army of demons in the Electric Age is extremely ferocious. This free third-party force has been fighting to regain its homeland.

They don't belong to the Duliba civilization, nor do they follow the Sangru civilization, but Su Yu has some admiration for their fighting spirit.

It's a pity that Moto can't enter the electrical age, otherwise maybe the demon army above may have its relatives and friends.

Come on, let's build!

Su Yu's current technology has reached the peak level of the first industrial revolution.

The problem now is to face the tide of demons.

There is also Thor who may attack him at any time.

The last time the Devil Legion fought in the Devil's Fortress, they dispatched Corpse Bats, so the air defense force is indispensable.

Su Yu worked on it for a long time, and finally saw an anti-aircraft weapon.

This is an existence that crushed all kinds of artillery during World War I.

In terms of performance, even during World War II, it was still ahead of the artillery of many countries.

This is the M1929 155MM plus howitzer.

30.9 times diameter, 17.5KM range, the first range at that time.

From the research and development to the next 30 years, there will be no lagging behind the howitzer.

Without hesitation, Su Yu directly came to 100,000 gates and placed them on his city wall. This is his most long-range firepower.

Of course, this is still the normal version, and I have a heaven-defying five-star upgraded version.

M1929 155MM plus howitzer (2000 points), direct purchase to upgrade to 5 stars requires 12,000 points.

Su Yu bought 100,000 doors and spent 1.2 billion points.

M1929 155MM plus howitzer (five-star)

Range: 50KM

Rate of fire: 10 rounds/min

:200000

Killing radius: 400 square meters

Yes, the range of 50 kilometers is almost catching up with some ordinary rockets.

There is also air defense force, Su Yu continues to search.

Su Yu discovered that there is a Longteng Kingdom's first air defense missile named Hongqi-1 in the system.

Shown in grey, the desired GDP target is also due.

And the description above says:

[The material for building this weapon has not yet been broken through. In the electrical age, with the development of integrated circuits and new material technology, this weapon can be easily manufactured. 】

Now that there are anti-aircraft missiles, some must be built in the future, because in the electrical age, humans can already manufacture jet fighters.

Ordinary anti-aircraft guns are extremely difficult to hit.

And Su Yu guessed that Sol should have quite a few planes like this at this time.

This kind of missile Su Yu needs 20,000 points to upgrade from purchase to 5 stars.

Therefore, entering the electrical age, it should be enough to spend 2 billion to build 100,000.

There are also 300,000 weapon platform slots vacant.

Su Yu is not in a hurry, as long as he has points, he can build it every minute, and after he gets there, he will see if there are any better weapons.

Moreover, the goal of calendar is not a trip.

Saul's big cancer must be removed, and then there is his own comeback plan.

He had a premonition that Xue Changgui's scientific and technological achievements were likely to change the future battle situation.

The entanglement effect Su Yu is really convinced.

And at this time.

Su Yu received a system message.

[573 Ding! It is detected that the advanced civilization of the Black Eagle Kingdom is still 1 day away from completing the task of resisting the demon army. It is very likely to get high rewards and successfully occupy the source vein!】

source mine??

[System: Source Mineral Lode: A larger-scale raw ore production site, but it is in the midst of competition from multiple forces, and currently has no ownership. 】

Su Yu was amused, this system now openly provides him with the information of the other party that can be detected.

Is this in a hurry? Worried that the forces behind the Black Hawk will gain an overwhelming resource advantage?

It's a bit interesting, I didn't expect that there are many benefits to wandering among several forces.

[Ding! The host please advance to the Electric Age as soon as possible, and seize the source mine!!!]

Su Yu glanced at the 20 billion or so points he had left, and said lightly.

【No hurry, talk about it tomorrow!】

【system︰......】

And Sol, who was besieged by hundreds of millions of demon legions in the electrical age, smiled.

He glanced at his system tasks.

[Please resist the attack of the demon army around the source vein, stick to it for 7 days, reward: 10 times reward for any weapon construction. 】

Make one, give ten, Saul burst out in his heart.

There is a source of mineral veins under his feet. If he wants to occupy this place, he will have to persist for a week, after completing the task.

"Su Yu, just wait for your death! You have never experienced the true strength of my Black Eagle Kingdom."

The first Dragonhawk modern war officially kicked off!

The fifth update today!.
