In this limited development time, Luo Ji had a lot of projects to deal with. Although he had adjusted the time flow, he was still living a tense life recently.

Especially in recent times, the mass production of dwarf tanks and biplane fighters, coupled with the formal establishment of project teams for the first-generation jet fighters and the first-generation aircraft carriers, and a series of major actions such as investment in research and development, have directly led to the

The economy of Luo Ji's Wanjie Civilization, which had just become affluent, suddenly became a little nervous again.

In the next few years, Luo Ji will obviously have to calm down.

If we add more projects, the financial pressure on the civilization of all worlds will be too great.

Of course, even if he doesn't add projects, he can still do other things.

For example, send out several reconnaissance teams to open up the horizons of the Western Desert and the Bitter Cold Land.

The discovery of the indigenous cities on the Far Eastern Prairie in his early years made Luo Ji clearly realize that he had been a bit slack in broadening his horizons in recent years.

The main reason is that the environment in those areas is too harsh. He has no plans to expand his territory into the desert or frozen soil in a short period of time, let alone build a city, so the exploration has been put on hold.

It wasn't until the group of natives from the Far Eastern Prairie gave him a heads-up that he started to send out reconnaissance teams again.

And just as he was opening his sights on the main continent in an orderly manner, the Nuclear Energy Research Institute built in the bitter cold land also officially sent a report.

On this day, the first nuclear reactor of his civilization was successfully developed!

This is a very important step for a civilization.

It’s not that you can make mushroom bombs, but that from this day on, this civilization has officially taken the first step towards the atomic energy age!

Atomic energy is a good thing. The energy it contains is many times stronger than ordinary energy.

In the real world, awesome aircraft carriers or submarines are all nuclear-powered.

Later, if conditions permit, he can also build a nuclear power plant, which will consume much less energy than a thermal power plant.

As for the mushroom bomb, as a strategic-level weapon, of course it must be developed.

However, you have no idea how useful it is.

At least for Luo Ji at this stage, even if mushroom bombs were developed, the deterrence of that thing would definitely outweigh its practicality.

When some people hear about mushroom bombs, they always think, 'Holy shit, this is awesome, invincible, I can destroy the world! Who else can be my opponent?'

In fact, that's not the case at all.

To put it bluntly, in the early days, mushroom bombs were just like paper tigers. It was very difficult to use them.

In the real world, the first country to create and use mushroom bombs was the Lighthouse State, and for a period of time after that, other countries had no mushroom bombs at all.

At this pace, if mushroom bombs were truly invincible, the Lighthouse Country would have brought nuclear peace to the world long ago.

But the reality is that there isn't.

Why is this? You are not so naive as to think that the people in the Lighthouse Country are gentlemen, right? How is that possible?

The actual situation is as mentioned above. During that period, it was really difficult to use mushroom bombs, unless what you wanted to do was to detonate them on the spot...

The fundamental reason for this situation is that the power supply battery of the detonation system in the mushroom bomb was not long-lasting at that time and could only last for about thirty hours.

At the same time, due to the heat release problem of the plutonium element in the mushroom bomb and the corrosion problem of the battery, after a mushroom bomb is assembled, basically every nine days it has to be disassembled, charged and replaced with parts, or completely dismantled and turned into

Component.

Therefore, at that time, the term "hoarding" of mushroom bombs basically did not exist, and assembly would only begin when needed.

After assembly, bomb delivery is also a problem.

Under the circumstances at that time, the only means of dropping bombs was to transport them by airplane and conduct airdrops.

Here, distance becomes a problem.

Taking off from the airport on your own territory and flying to someone else's territory to drop mushroom bombs? It's not as easy as it sounds.

At that time, the flight time and distance of aircraft were very limited, and the mushroom bomb itself had a time limit due to the above reasons. Enemies that were slightly farther away were not within your strike range.

And if you assume that the enemy is just within your attack range, then according to the technology at the time, airdrops basically have no accuracy. Under this premise, it is impossible to carry out a precise attack on the enemy army.

The only thing that can be done is to blow up the enemy's important cities.

But now the problem comes again. If you want to bomb an important city, you have to know which one is the first.

In other words, you must have a detailed map of the enemy...

But the enemy is not stupid, how can he easily expose the detailed map information of his territory?

In this way, the success rate of bombing is really too low. If you want to blow up a city, usually one mushroom bomb is not enough, and the manufacturing cost of mushroom bombs is so high. If you are desperate and forcefully drop the bomb,

I don't know if the other side will be neutralized, but your wallet will definitely be neutralized.

In other words, the financial pressure is great, and while it is difficult to handle, it is also a bit overwhelming.

This is what actually happens.

Combining the above reasons, for Luo Ji, the mushroom bomb was obviously not as effective as Mia's lava star.

He attaches great importance to the development of atomic energy. As for mushroom bombs, they are just like that in the early stage.

The reason for research and development is with the mentality that something is better than nothing.

After some time passed, Luo Ji couldn't help but pull out his system map when he saw a document in front of him.

This document was sent by the Construction Engineering Department.

What he mentioned was another huge project of his civilization of all realms, the construction of the Great Wall!

In recent years, with a full labor force, Luo Ji finally built the Great Wall all the way to the east.

Compared with the cities in the Central Plains region, there are actually relatively few grassland cities in the Luoji World Civilization, only a dozen or so.

Based on this premise, where should the Great Wall be wrapped? It became an important issue that required Luo Ji's personal confirmation.

Luo Ji also thought about this issue for a while.

For long-term considerations, he still wants to acquire more land on the eastern prairie.

But I am afraid that there will be too many packages at once, and it is too far away from the cities and fortresses in the rear. Once the war comes, it will affect the speed of support, and it will not be easy to garrison at the same time.

In this way, after Luo Ji weighed it in his mind for a while, he finally decided to play it safe first.

Taking the farthest distance on the border as the standard and reserving the width of two cities is almost enough.

In this area, more than two cities can be placed, because in addition to width, there is also length.
