Xiao Nuo talked for a long time, and Wang Dong gradually understood, he found that whether it was Sky City, class exchange, or transformation skills, they were a good complement to their own strength.

And it has a great effect, just like the city in the sky, before he was worried about how to build his own base, after all, there are many things to do to build a base out of nothing.

Since it is a base, there must be residents, and you can't create something out of nothing, right? If there is no one, how can you build the city wall? How can you recruit city guards?

And the most difficult part is that most of the survivors have now gathered in various bases, and those cities before the end of the world have completely become a zombie city.

Trying to lure the survivors with a newly established base is a complete fantasy.

Therefore, it is very difficult to build a base out of nothing, and this is also where Wang Dong is difficult.

But now I didn't expect that after being promoted, I actually got a city in the sky, and after having this city in the sky, I saved eighty percent of the trouble.

There's no need to go through the trouble of attracting any survivors, just let it be, if you have it, if you don't, if you don't, you don't.

There is no need to build a city wall, and I believe that since Xiaonuo said that the defense of Sky City is the strongest, it is definitely not a lie.

There is also no need to worry about being attacked by a large-scale zombie tide, after all, among the zombies now, the number of flying zombies is still very small, and the vast majority of them can't fly.

And the escort team doesn't need to be trained, it only needs to create some troops, and it can completely assume the heavy responsibility of the city guard.

Thinking of this, Wang Dong couldn't help but get a little excited, and then he clicked on the exchange shop with anticipation.

Castle in the sky

(Note: The materials used to craft Sky Castle are not only light, but also unusually strong.) It can afford up to a million people to live in it.

In order to levitate and move the Sky Castle, it needs to consume energy, in addition to the energy that the Sky Castle automatically absorbs every day, it also needs to consume 100,000 silver coins every month, which is used by the gravitational device.

In addition, the city defense facilities in the city, such as automatic arrow towers, automatic turrets, etc., also need energy to maintain. ）

...

Transformation skills

Price: 1 copper

...

As soon as Wang Dong saw the explanation above the Sky City, he was a little depressed, he didn't expect that the flight and levitation of the Sky City would also need energy support.

100,000 silver coins per month, 120 silver coins a year, which is not a small amount.

But after thinking about it, he also understood, after all, energy is conserved, and if he wants to make such a large city go to the sky, it only consumes 100,000 silver coins every month, which has already made him very surprised by the technology of the pet beast empire.

But in this way, he will have to find someone else to share the money for himself, and if he is allowed to pay it himself, it will definitely seriously delay the growth of his strength.

Originally, he was not going to attract those survivors, but for the sake of this large amount of expenditure, and in order not to delay the growth of his strength, it seemed that he could only attract survivors.

If you then spread that expense among the survivors each month, you may not only not be a drag on yourself, but you may also be able to make a lot of money.

After all, for all people after the end of the world, nothing matters, safety is the most important.

Just rent out the houses in this sky city, rent them and don't sell them, and then collect a sum of money every month, and then let your own escort team provide security for the entire city.

It's like in a pre-apocalyptic city, the neighborhood with the best security measures is often the most expensive. And although this kind of community is very expensive, there is no worry that it will not be sold.

Therefore, Wang Dong believes that there will definitely be many people who will choose to live in the sky city, after all, this kind of city flying in the sky will definitely give people a sense of security.

After determining the future development direction of Sky City in his heart, Wang Dong opened the column of pet beast exchange again, and saw that the potential level of all pet beasts in it had been increased by one level, and the exchange price of the laser scorpion had also come out.

Then I found out that this time there was an extra class exchange in it.
