After listening to Chen Yuan's suggestion, Du Mei nodded seriously, and she said sincerely: "Chief Chen, thank you so much this time." I can't imagine what the outcome would have been without you. So I decided that in the future, all the diesel and gasoline that our oil city will give to the steel castle will be supplied at cost price. In addition......"

Du Mei threw a bombshell next: "The Iron Castle will own 20% of the shares of the entire Oil City." It has the power to free trade, investment, conditional garrisoning, and intelligence sharing in the oil city. In addition, the residents of the Iron Castle will enjoy the same treatment as the residents of the Oil City in our Oil City, and can live, do business, work and study freely. ”

Hearing this, Chen Yuan couldn't help but be taken aback.

You must know that the shares that Du Mei said are not only the shares of the Oil City Petrochemical Company, but the entire Oil City! So what is the concept? This means that 20% of the entire oil city is now a steel fortress. Including population, supplies, and so on.

And it is also possible to garrison troops. This is no longer as simple as an alliance between two forces.

Chen Yuan asked, "City Lord Du, do you really want to do this?" ”

Du Mei nodded, and said as a matter of course: "This should be the case. If it weren't for you, we would have died by now, and the supplies would have fallen into the hands of others. So I think that's still a few. In addition, I would also like to hire you as the honorary lord of our Oil City. ”

Okay, that's the equivalent of a merger. Chen Yuan was also promoted from the title of castle chief to the city lord at once.

In fact, this is not difficult to understand, after all, they have just offended such a big force as Xinha City, and if Oil City wants to survive in peace, it is natural to hurry up and find another thigh.

The Steel Castle is one of the few powerful settlements in the vicinity that can compete with Xinha City. Moreover, the people of the Iron Fortress are more trustworthy and reliable than other settlements, and the system of the settlement is more gentle.

The most important thing is that after seeing the power of the new weapons of the Steel Castle, Du Mei is even more convinced of the strength of the Steel Castle and is full of confidence in their future. If you don't hug their thighs, who will hug them?

At this time, Du Mei said tentatively with a flattering attitude: "City Lord Chen, are you selling your new weapon to your family?" You see, our walls have just suffered a lot of damage, and we need more protection before the walls are repaired and the new city is built. ”

Chen Yuan smiled and said: "This new assault rifle was jointly developed by us and the Shenwuguan settlement, and the two sides agreed that the new weapon could not be leaked out for the time being. If I need to help defend here, I can arrange for an infantry battalion equipped with new assault rifles to stay behind to help. ”

*********

The Daqing crisis was over, and Chen Yuan and the troops of the Self-Salvation Army stayed behind that day to help clean up the battlefield. The next day, he returned to the Iron Castle.

At this time, Chen Yuan's identity was already an honorary city lord of the oil city. When he and the troops of the Iron Citadel left, the soldiers and civilians of the vast oil city greeted them.

In order to strengthen the defense of the oil city, the 1st battalion of the 3rd regiment temporarily remained in the oil city.

Next, at Du Mei's invitation, the Iron Fort Military Intelligence Bureau was also stationed in Oil City to assist them in carrying out intelligence work, focusing on counter-espionage.

The construction of the new city of the oil city was also carried out by the Iron Fortress. After all, he is also an honorary city lord, and the Iron Castle has made a lot of efforts in the site selection and construction of the new city of Oil City.

It can be seen from the old city of the oil city that they are very lacking in talent. At the beginning, the city construction plan they came up with was simply miserable in the eyes of professionals.

In order to save the construction period, the designers of the oil city actually chose an island in the middle of the lake with an area of only 1 square kilometer to build the city.

This seems good, it is an island in the middle of the lake, and the closest place to the land is also 800 meters. The area of 1 square kilometer is 1 million square meters. 100,000 people live, each person can also have 10 square meters of activity space, plus if you build high-rise housing, you can also save a lot of area. 100,000 people should be able to live.

But when the experts of the Steel Castle saw the design of the new city, they rolled their eyes on the spot and said, "What a joke is this? 1 square kilometer, it looks like a lot of area. But in fact, if you have to deduct the area of city walls, roads, and public facilities, there is not much land left. ”

"Besides, 1 square kilometer lives 100,000 people, and this population density is completely explosive in any city in peacetime. In the past, even the most densely populated district in the northern capital had a population density of only 30,000 people and 1 square kilometer at its peak. It was only in the Mong Kok district of the Hong Kong government in the past that the population density at its peak could reach such an exaggerated level. ”

"But the infrastructure conditions are completely different. The tall buildings of the people are contiguous. You are now building a city on a barren land, how can you build so many high-rise buildings at once? ”

Chen Yuan told Du Mei about this, and Du Mei was dumbfounded. In the end, he was helpless, so he threw the pot to Chen Yuan again.

Chen Yuan, on the other hand, had the experts of the Iron Castle relocate and design it.

The lake land is made up of a total of 132 large and small lakes, covering an area of about 1,600 square kilometers.

The experts at the Iron Castle carefully reviewed a detailed map of the entire lake and then went on a field trip.

In the end, a piece of land in the northwest and central part of the lake land was chosen.

This piece of ground is actually a small hill, no more than 15 meters high. It is about 2 kilometers long and 1.5 kilometers wide, surrounded by lakes, and connected to other land by three narrow roads, but none of them are more than 200 meters wide. It's almost the same as the island in the middle of the lake.

3 square kilometers of land, no parks, less greenery, population density of more than 30,000 people 1 square kilometer, can also be accepted.

And the new city, which has been redesigned by the experts of the Steel Castle, is much better.

The experts are going to build it into a star-shaped fortress similar to the city of Burganhe. There are three roads inside and outside the city wall, the first of which is 15 meters high and is built close to the lake, leaving no place to stand. The second road rises up the terrain to a horizontal height of 20 meters. The third wall is 25 meters horizontally.

A section of the three roads that were originally connected to the rest of the land will be dug up to create a suspension bridge. When the enemy is attacking, the drawbridge can also be raised.

There are countless defense towers in the city, which can form an effective surveillance network against the ground and air, and there will definitely be no defensive blind spots. It's not easy for the flying corpses to come in and sneak attack.

In addition, the experts of the Steel Castle have also planned public facilities such as shopping malls, markets, public toilets, schools, hospitals, and stadiums in the city. Of course, in order to save space in buildings, such as schools and playgrounds, these are built on the roofs of some large buildings.

Seeing the design drawing, Du Mei's eyes couldn't help but light up.

According to this plan, the new oil city built not only has a beautiful environment and sound functions, but also has extremely high defensive performance.

This is a doomsday refuge, this is simply a tourist city! Just by looking at the appearance, there must be countless people who want to be able to live in such a fortress. At least Du Mei is very excited now, hoping that this new city can be completed as soon as possible.
