In the Yangtze River basin, under the surface of the river, groups of fish-man soldiers showed their posture underwater, all the way through the turbulent river, and quickly approached the Yangtze River fortress of the Ten Thousand Worlds Civilization.

For the fishmen, the day was no different than usual.

And accidents often come on such days......

The violent roar of the explosion directly exploded the entire calm river, dragging the fish people in the water into fear and death in an instant!

In the distance, on the deck of the Pioneer, Yuan Xi silently put down the telescope in his hand, and then said to the adjutant standing beside him......

"The mine operation was successful, and a signal was sent for the salamander troops to pull up an underwater cordon at a predetermined location to clear the remnants."

On both sides of the Yangtze River basin, the salamander warriors who received the signal moved quickly.

After rushing two steps on the shore, he plunged headlong into the rushing river.

The Yangtze River basin one kilometer ahead is almost full of mines! It was the latest work of the dwarven master Bart Brutehammer, and I heard that it was inspired by the words of their majesty.

This thing is extremely powerful, and the only drawback is that it can't distinguish between enemies, and sometimes it can hit enemies while restricting their own movements.

So that piece of the Yangtze River basin, even if it is their own now, they dare not approach, so they can only wait here.

The existence of mines has undoubtedly effectively curbed the depth of the fish people.

After this battle, if they want to sneak in along the Yangtze River basin in the future, they must first see if they have the strength to pass through this mine area.

After that, the Yangtze River Fortress will undoubtedly be able to live in peace for a while.

On the other hand, Reddis is not at peace at all.

This state of being controlled by others is really terrible.

Previously, he had always regarded killing his younger brother Odis and regaining the throne of the Grey Elves as his highest goal.

And now, it seems, he was too naïve.

The existence of the civilization of the Ten Thousand Worlds was like a bucket of ice water, pouring it on his head, making him clearly aware of what it means to have people outside of people, and there are heavens outside the sky.

From the current point of view, the opponent's steel fleet is not something that his Black Sail battleship can compete with at all.

The hole cards that can pose a threat to the steel fleet in his hand are basically only Hydra.

In the face of such a powerful opponent, the huge psychological pressure made Reddish increasingly anxious.

And at this moment, Luo Ji, who is far away in Spiegel City, is the opposite.

After the first batch of mines was produced and the mine defense line was laid in the Yangtze River basin, he left the matter there for the time being and handed over to Yuan Xi, the naval colonel, to deal with.

On the one hand, he has a lot of things to do every day as an emperor, and it is impossible to keep an eye on this piece all the time.

On the other hand, it's because he can't manage it if he wants to, and in a short period of time, he has no way to take that hydra, how else can he do this?

But fortunately, in this area, Reddis is the same.

Luo Ji didn't have a problem with Hydra for the time being, and Reddish was also afraid of Ysera's existence and didn't dare to play his last hole card again, and for a while, the two sides also formed a delicate balance.

During this period, Luo Ji apparently shifted his attention completely to other developments.

Over the years, probably because of the large increase in the population base, the population of the various regions of the Ten Thousand Worlds Civilization has also begun to increase at an even more exaggerated rate.

Among them, the southeast region is already overcrowded.

At this time, Luo Ji issued a very important decree, that is, to demolish the city wall and expand the area of the city!

Of course, this demolition should also pay attention to a step-by-step process.

The first castle to be demolished was the eastern city in the southeastern region.

The location of this city, which is located in the Central Plains, is a fairly in-depth city.

According to the current pattern of civilization in the world, in the southeast, the invading enemy cannot cross the natural defense line of the Yangtze River, and it is impossible to threaten the cities behind.

In this era, the outer city wall still has the value of existence, but the inland city, continuing to stand the city wall, the actual significance is not large, it does not play much defensive role, but will affect the expansion and development of the city, and the demolition of the inner city wall has become a necessary process.

The whole project went well.

The follow-up expansion and development plans of Donglincheng have also been put on the agenda.

As long as this wave of construction and reform of the eastern city is successful, then in the future, other cities in the Central Plains will also usher in this step, to a certain extent, this is also an inevitable development of the times.

Now pulling the perspective back to the side of Spiegel City, Luo Ji has been very concerned about the research and development progress of various projects in the Science and Technology Institute recently.

The latest piece of good news is that his goblin inventors have overcome the hurdles to create dry batteries, which will soon be mass-produced, so that the flashlight will be successfully used in everyday use.

During this period, the research and development of generators has actually made progress.

It's just that, according to Luo Ji's meaning, he didn't let the goblin scientists do any portable generators, so he didn't need that kind of thing at the moment.

What he needs is a thermal generator with a huge output power that can power an entire city!

For the crazy idea of His Majesty the Emperor, the group of crazy scientists of the goblin clan seemed to be in high spirits, and the two sides simply hit it off and directly devoted themselves to the research.

However, it is obviously not easy to manufacture such a high-power generator.

Of course, the more important thing is that the output power is too high, which can easily lead to the instability of the machine and the danger of uncontrollable occurrence.

In this regard, Luo Ji naturally relied on his common sense of modern people to help them to a certain extent.

For example, it doesn't mean that you really have to use one generator to do it all, but ten or twenty can actually do it.

They can divide an entire city into several small areas that are relatively easy to manage and control, and then connect each small area with a generator with wires, and a generator only needs to provide a stable amount of electricity to one area.

I have to say that Luo Ji's words successfully brought some crazy scientists who really want to use a generator to power a city out of a dead end.

However, from the perspective of the whole thing, the difficulty of this matter has not been reduced much.

As the number of generators increases, so does the number of wires, which naturally increases the difficulty of designing the electrical system of an entire city.
