Bengtie, sandbox development, how did they run out!

If he had not encountered the Immortal Boat, Shen Yi might have spent his technology points on these two technologies.

But now, his treasury is overflowing with resources, and the exploration mission is also carried out by the Sifang Lanjing sent by the immortal boat Luofu.

Therefore, he can fully prioritize research on the newly unlocked level 5 technology.

Each level 2000 technology requires 4000 technology points, while level doubles that to .

This was a huge number for Shen Yi before.

But now, he only needs ten rounds to complete a study.

Compared to the four-level technology, which has six items, the five-level technology only has four items:

[1. Planetary Orbital Cannon: Allows civilizations to build planetary-class low-Earth orbital cannons. After unlocking the Colossus weapon technology, it can be upgraded to the "Colossus" unit.]

Astra Militarum: Improved combat grid, allowing up to three fleet units to be merged into Astra Militarum.

[3. Cold Nuclear Fusion Energy: Low-temperature nuclear fusion will promote the production of a new generation of ship-borne fusion reactors, increasing all attributes of fleet units by 20%]

[4. Entropy Recursion Hypothesis: The universe seems to be inexorably moving forward. This trend cannot be reversed... but as long as the cost is high enough, all of this can now be overturned.

(No practical use, it is a pre-reverse engine technology)]

First of all, the planetary orbital cannon was put on Shen Yi's research agenda during Grammer's expedition to help Luofu escape.

And after a night's rest last night, the technology has been researched!

Now, the production and construction plan of the planetary orbital gun is quietly lying in the new buildable unit project column in the military areas of various cities.

In addition, don’t forget that there is another item in the level six technology that Shen Yi has already unlocked in advance.

That is the [Colossus Weapon] randomly given by Cangcheng.

After the planetary orbital gun is built, Shen Yi can directly spend productivity to upgrade the device to a Colossus weapon.

And the first time you upgrade, you can get "Neutron Annihilation" and "Earth-shattering Star" for free!

It's almost like giving him two planet extinction orders!

Without further ado, I must build the planetary orbital gun immediately!

Shen Yi couldn't wait to open the construction menu and selected the planetary orbital gun construction project in the military unit.

This project requires 3000 Production, as well as 500 Common Materials and 300 Precious Materials.

Oh my god, that’s really expensive!

And that’s not all. The most expensive thing is its maintenance fee, which is as high as 50 gold coins per round, as well as 30 common materials and 20 precious materials.

This is equivalent to directly using up all the materials Shen Yi collects in each round.

If it were something else, Shen Yi would definitely not be willing to spend so much materials to raise it.

But it's a planetary orbital gun!!

It can also be upgraded to a Colossus weapon!!

If we don’t build it now, when will we build it?

Shen Yi decisively pressed the mouse and started the construction task.

As the machinery in the military factory roared, the prototype structure of the planetary orbital gun began to take shape.

Because the capital has the highest productivity, Shen Yi assigned the task of building the railgun to the capital.

In this way, the construction can be completed in just 15 rounds.

But Shen Yi knew very well that this was not the end.

After the planetary orbital gun is built, he will need to spend another 5000 production capacity and more materials to upgrade it to a Colossus weapon.

At that point, the mission is completed.

In other words, spend money slowly and then it will start.

Although the treasury of his current civilization is very solid, when he looks at the maintenance costs, when the infrastructure, military units and weapons and equipment increase in the future, the maintenance costs alone will be a big problem.

The maintenance cost of the planetary orbital gun is 50 gold coins. Shen Yi conservatively calculated that the maintenance cost of the Colossus is at least 100 or even 200!

At present, my gross income after deducting maintenance costs is only 170. If I can't afford to maintain it after building it, I will lose money.

What's more, the special weapons equipped by the Colossus also require maintenance costs.

For example, Earth-shattering Star and Neutron Annihilation, both of them have maintenance costs as high as 50!

This is already the maintenance cost of the planetary orbital gun.

Although the national treasury still has more than 10,000 gold coins, which is very full, but if there is only outflow and no inflow, and there is a deficit every time, even the largest family will be emptied.

Gotta find a way to make some money!

Shen Yi's eyes rolled——

Eh!

I have a solution!

Why not take advantage of Xianzhou?

Bah, bah, bah, what nonsense! It should be called win-win cooperation!

After all, after a night of reconstruction, Xianzhou Cangcheng and Xianzhou Luofu were almost back on track.

The trade functions of the two giant ships can naturally also be used.

Chapter 62: Rogue Traders and Trade Alliances (Part )

As we all know, playing Civilization without cheating the AI ​​is like playing games without playing O God, or reading the Four Great Classics without reading Dream of the Red Chamber. It shows that this person lacks humanistic attainments (paper) and self-cultivation...

I forgot about it later.

In short, in the game Civilization, players can cheat AI coins through various channels and means.

For example, you can make a deal with the AI ​​that is at a disadvantage in the war, form a war alliance, let it pay the money, and you send the troops.

But after receiving the money, the player simply refused to send troops and just watched the fire from the other side! When the friendly army was in trouble, he remained motionless like a mountain!

This way you can get AI's money for free.

Alternatively, you can sell resources that will only take effect in the next round to the AI, and then declare a surprise attack on the AI ​​after the AI ​​pays.

Then the player has obtained the money, but the resources traded out will be automatically taken back by the system because it has not yet reached the effective round.

In this way, AI spent money but did not get the goods. This behavior is called "fraudulent advertising."

Of course, Shen Yi already knew that the civilization behind the screen was not AI, but a living civilization, so this method would definitely be useless.

What's more, Xianzhou is his friendly country and a third-level military ally. It is somewhat unreasonable to betray his own teammates.

To sum up, obtaining gold coins through normal trade means is the best option.

To open trade between two civilizations, the [Rogue Trader] municipality must be unlocked.

This municipality is only a second-level municipality, and Shen Yi had already unlocked it long before he encountered the Xianzhou civilization.

By the way, in this "game", players can trade with any civilization except enemies.

Regardless of whether the other party is a neutral civilization or a friendly country.

However, if you want to form a trade alliance, you must reach level 2 diplomacy.

After forming a trade alliance with a civilization, all trade routes between the two sides can provide additional gold coins.

Therefore, Shen Yi decisively opened the diplomatic system and submitted an application to establish trade with the two immortal ships, Cangcheng and Luofu.

The other party also agreed to Shen Yi's application very readily. Not to mention that it was thanks to the Grammer Empire that the two immortal ships survived.

Just because forming a trade alliance has only benefits and no disadvantages, Xianzhou can't find any reason to refuse.

As prompts popped up one after another, Cangcheng and Luofu both became trade allies of the Grammer Empire.

Once you have established trade relations, you can create trade routes.

Each city and commercial district a civilization owns can add one trade route.

Capitals with palace bonuses can also gain an additional one.

That is to say, all the cities in the Grammer Empire combined can create a total of 7 trade routes.

In addition, trade routes require "Rogue Traders" to conduct trade.

This thing is the merchant unit in "Civilization 6". It needs to be built with production capacity, or it can be purchased directly for a few hundred gold coins.

The difference is that the merchants in the civilization have no combat power, while the trading ships of the Rogue Merchants have frigate-level firepower.

Soon, all seven trade routes were in operation.

Each trade route can bring 50 gold coins of gross profit to the Grammer Empire each turn.

7 trade routes, adding up to a total of 350 gold coins!

Helping Xianzhou quickly rebuild order is indeed the best policy. If the other party does not rebuild it, I will never be able to enjoy such a high income!

The completion of the trade route directly filled the gap in subsequent maintenance costs, and now Shen Yi can boldly build Colossus weapons.

After a while, as the prompt "Planetary Orbital Cannon Construction Completed" popped up on the screen, Shen Yi immediately switched the camera to the cell where the turret was located.

Although he could only watch it through the screen, Shen Yi still showed an expression of amazement.

The huge rail gun goes beyond traditional military concepts and perfectly integrates technology and aesthetics.

The main structure of the railgun is made of high-strength nano-alloy, covered with a thin layer of energy barrier, and the arcs flowing above it are like ripples on a lake.

Its huge body is almost comparable to a city, like a mountain made of metal and energy, towering into the clouds and reaching the sky!

As a railgun, the muzzle area is naturally its most eye-catching part.

This area is designed to be a huge black hole entrance that seems capable of swallowing stars, surrounded by layers of energy shields and focusing lenses.

These lenses appear in different colors and lusters, from deep blue to fiery red to brilliant silver-white.

They are intertwined and reflected with each other. When the torrent of energy gathers inside the muzzle, these lenses will guide and focus it to the extreme, forming a terrifying force that can destroy stars.

Even before it opened fire, Shen Yi could imagine how powerful it was.

The Star Destroyer Cannon is already so powerful, so how powerful will the Colossus weapon be?

With this idea in mind, Shen Yi eagerly chose the upgrade project.

Upgrading the Star Destroyer to a Colossus weapon requires a full 10000 production.

In addition, the weapon must be constructed in space.

Because the Colossus weapon will be as large as the moon after it is built, there is simply not enough space on the ground to produce this giant unit.

This problem certainly does not pose a problem for the Grammer Empire, which already has the ability to build in space.

Shen Yi doesn't have to worry about anything now. He just needs to wait for 50 rounds and then he can enjoy the fun of destroying a planet with the Colossus weapon.

Although his light arrow failed to kill Yu Huang and Lisa, from a normal logic point of view, they had just suffered a defeat, their leader was seriously injured, and they knew that the other party had the help of the star god.

Even those mentally ill people would choose to temporarily cease fire and recuperate.

They did so. If they really wanted to chase him, they would have caught up with him last night when Shen Yi was sleeping.

Since they haven't launched a surprise attack yet, they must have some concerns and plan to gather their strength before launching a large-scale invasion.

What Shen Yi needs to do is to develop quickly and build the Colossus weapons, so that when the people of abundance come, he can give them a surprise.

In addition, the work of expanding territory must also be kept up.

The three cities of Terra Starlight have almost completely plundered all the resources on the map. If they want to continue developing, they must carry out interstellar colonization.

Interstellar colonization requires the support of two municipalities. In addition to the previously mentioned [Interstellar Imperialism], it also requires the support of the [Interstellar Immigration] municipality.

With the empire's current culture, this municipality can be completed in just ten turns.

Therefore, Shen Yi didn't have to consider this at all and started looking for habitable planets on the map.

The scientific research fleet had previously found a habitable planet, and Shen Yi would give priority to sending the colony ship there.

But how could one be enough? If the people of abundance saw this, they would think we couldn't afford to colonize!

Let’s start with ten!
