In the city, there are countless roads leading to the dungeon, for those relatively small bunkers on the periphery, several bunkers share a passage, as for those air defense towers, each air defense tower has a passage to the dungeon, the most obvious feature of the air defense tower is that it is large! An air defense tower is half a block big, and in the later period of Su Fan, there is a more crazy super complex tower jihua, this jihua is going to make a tower bigger than the fortress outside the Royal University of Grass! A tower with a passage to a dungeon is not much.

As for the distribution of these towers, it is not a problem, ordinary civilians and untouchables or something, it is already thankful that they can live in the city, and they don't care if they are hundreds of families crowded into one battle tower, or how many families live in one bunker, and some middle-level rich people will not care if they buy a layer of battle towers to live in, as for the richer and richer?

The construction team sent by Davis to Su Fan is worthy of the top construction team, and the second comprehensive tower is under the full operation of the combination of hundreds of magicians and magicians, and it will not move after building a foundation...because there are no materials, last time Cool Iron Hammer and Kaede just bought the materials of a comprehensive tower, but Su Fan made a mistake, so he had some more, and he had to buy materials again.

But this time you don't need a cool hammer to buy materials, because there is silence! Silence is a ground effect spaceship, and a ground effect spaceship relies on ground effects to fly, that is to say, as long as it is close to the ground, even if it is on land. It's like a hovercraft. However, the Ground Effect Ship can fly higher than the Hovercraft. Silence can fly to 400 meters in the air, which is no pressure for crossing mountains and mountains, so this time I went out to buy materials silently.

Su Fan brought all the space equipment that he could find silently, and of course, Victoria, the ultimate artifact used as a storage prop, was also stuffed into the silent cabin.

Watching the huge ground effect plane slowly rise and slowly accelerate, after Zuihou disappeared into the air, Su Fan went back, according to the silent speed. A round trip takes a whole day, and it takes at least two days to go to another city, including the time it takes to buy things and the materials needed in one city.

Taking advantage of this time, Su Fan is ready to find a good place for the airship manufacturing factory, of course, the airship manufacturing workshop is the control tower, but the top of the command tower is not cement, but a metal cover, after the airship is manufactured, it floats out directly from the top of the workshop like a man in the red police. The airship is your top priority, so you must have an anti-theft and anti-voyeurism. And where it is easy to defend.

This place was finally chosen in a vacant lot not far from the Fit Laboratory, and in the future, the airship would depend on him, and he couldn't always rely on those who borrowed from Davis, right? Although this laboratory disrupted the planning of several blocks in the center of the city, there was no way to do it, and Fit would also choose a place, and the place where he chose the laboratory was the safest place in the territory.

The main body of the city was roughly planned, and the city design drawings were handed over to the construction team, and the first thing to start was of course the airship factory, and the weapon system of the God's Scepter that Su Fan had never forgotten had to rely on this factory to realize it, and now there were no materials, so the construction team could only dig a big pit first and then rest, waiting for the silent purchase of materials to come back.

The city is currently planned to be 2 million people, of course, it is impossible to complete it in a short period of time, the way the city attracts the population is very simple, that is, do nothing, just put up the city's sign, this shijieshijie is very dangerous, not to mention those dangerous monsters, the uncivilized race that can be seen everywhere, that is, all kinds of thieves also want people's lives, and the sea of people who want to get the protection of the city goes, but there are many people in the city and few cities, and they can enter the city, and get the protection of the city is what every civilian hopes the most, no matter what the city is, how to live in the city, in short, as long as you enter the city, it's better than living outside the city every day in fear, only those nobles have the identity to choose the city.

Therefore, as long as the city establishes the main body, and then signs it to the outside world, it is good to want to join the population of the city, and some displaced people or untouchables can indeed live after entering the city, but the place of residence in the city is not free, it needs a price, the untouchables and the displaced people have to borrow from the city, and then work hard to pay it off, and this debt is not earned for a lifetime for them, and the interest can be repaid at most, which leads to the civilians who have changed from the displaced people to the civilians from generation to generation can only live at the bottom of the city。

Despite this, many outcasts and untouchables know it, but they still choose to enter the city, after all, they will not suddenly rush out of the city to eat themselves by a group of uncivilized races, and they will not rush out of a slave hunting team to capture themselves as slaves.

The speed of silence can reach up to Mach 0.7, at this speed, they returned to the territory in the afternoon of the third day, and then Su Fan drove the construction team and the slaves out and started to work, in order to establish the territory as soon as possible, she adopted the policy of three shifts, and the slaves only worked in two shifts, in order to ensure the lighting of the construction site, Su Fan removed a few searchlights and sent them to the construction site, when the searchlights were in scattering mode, they were much stronger than magic lighting.

The top-level construction team is the top-level construction team, and the level gap between the top students and the scumbags is even more exaggerated, a small command tower (laboratory) and a large command tower (airship factory) Under the full efforts of this top-level construction team, it was all completed in just one month, including some important facilities inside, as for the ordinary construction team that was found before? They had just laid the foundation of a high-level battle tower in the big pit dug by Su Fan with cannonballs.

After the construction of the laboratory and the airship factory, the airship manufacturing team and Steng moved in, and silently went to buy not only a lot of building materials, but also a lot of daily necessities, enough for all the people in the city now, after Sten got into his laboratory, he spent two days sorting it out, and then began to continue to study his alchemy.

The airship factory has long been cleaned up by the slaves, and some alchemy tables from Davis have been placed, and the airship manufacturing team has begun to work, in order to produce the airship as soon as possible, there are some cranes and other things in the laboratory, which are used to lift some airship skeletons or something, as for the source of the crane, of course, it is used by the Shane sisters to lift seaplanes, and they can't use it, so they are dismantled and placed in the airship manufacturing workshop.

Time flies, when the main body of the four high-level battle towers is all completed, the first airship finally flew out of the production workshop with difficulty, the super Hercules airship in Gaul and this Shijie's airship are only the same in principle, the others are 108,000 miles apart, and the materials for making the airship are provided by Su Fan, the alchemists don't know anything about this polymer, they can only use the most primitive shaping technology to forcibly deform it, and the manufacturing process is very difficult.

Super Hercules has a huge body that is eight hundred meters long, three hundred meters wide, and two hundred meters high, and it is impossible to put such a large thing in the factory, it can only be assembled outside, according to Su Fan's requirements, the airship can be disassembled, the huge airship is divided into sixteen parts, and the part of the keel needs to be fixed with a special oversized bolt, and its strength must be guaranteed, so that each part can be manufactured in the factory.

Now that this huge airship has been assembled, an alchemist is doing Zuihou's inspection, and the airship uses the most commonly used magic gas for this shijie airship, which is less dense than hydrogen, so this huge airship can carry nearly a thousand tons of cargo, a hundred tons more than the original.

In order to control the lifting of the airship, inside the huge airbag of the airship, there are several airbags made of elastic materials, and the height of the airship is adjusted by inflating or deflating the airship, because the inside of the huge airbag of the airship is composed of a large number of elastic and non-haode hard canisters, and if you force the air to pump, it will be flattened by air pressure and cannot be restored to its original appearance.

The airship control lifting is a set of air pumps, and the forward power is a propeller-type magic crystal engine, the speed is about the same as the airship in the sky, and a streamlined pod is exposed under the airbag, and some hardpoints are deliberately left outside the pod to mount some space-based weapons, as for what, Su Fan is researching and unlocking.

At the beginning of the commissioning, under Su Fan's order, the air pump inside the airship began to work, and the special magic gas was filled into the airbag of the airship, and the air inside the airbag was driven out, and the air tanks inside the airbag were communicated with special pipes, and the air inlet and outlet were at both ends, when the magic gas was filled from above, the air was driven out, and there would be no residue, and the pressure on the ground of the huge airship was getting smaller and smaller.

When the main airbag of the tube combination made of hard polymer was filled, the pressure of the airship on the ground was only a little bit, and then the pumping machine began to inflate the lifting airbag, and the huge airship finally began to float slowly, until it floated to a few hundred meters in the air, the alchemist who controlled the airship stopped inflating, and pulled out part of the gas, the airship first shook for a while, then stopped, after a while, the magic crystal engines on both sides of the airship slowly moved under the drive of the propeller, and after a circle around the city, it slowly landed in place。 (To be continued......)
