Chapter 886

Now, Di Ping glanced at the buildings above and found that the price was not less than 100,000 crystal coins. Looking at the string of zeros behind each building, he only felt his eyes turn green.

In addition to the cheaper smart resource station, but it also costs 50,000 crystal coins. He has been struggling recently. He went to grab food from the tiger's mouth. He almost got 10,000 crystal coins, and now any building costs more than 50,000. , so that he won't be annoyed.

What annoyed him the most was that he appeared in the building arena and the hero cemetery before, and it used to cost only 1,000 crystal coins, but now, 100,000 crystal coins are not discounted, and the arena is as high as 200,000 crystal coins. Coins, how can this not make him angry.

Did you know that he built these two buildings first?

One or two thousand crystal coins are nothing to him now, but regretting it is useless now. With his understanding of the system, he cannot have room for negotiation.

"Master System, let's discuss, the arena will be cheaper!"

In the end, he still did not give up, and humbly pleaded with the system.

But the system was still as cold as ever, with no sound at all, as if it hadn't heard Di Ping's words.

"Okay! Don't beg you, 200,000 yuan, I don't believe I can't earn it!"

Di Ping waited for a long time with a shy face, but did not wait for a fart, which made Di Ping very annoyed, and his face darkened angrily.

Unhappy, I closed the building page and returned to the main page. Sure enough, the system interface was updated again. A white city wall appeared at the base, encircling the entire base in the middle, and a pitch-black cannon appeared at every break in the city wall. A teacup-sized muzzle was slanted toward the sky.

On the four watch towers around the castle, there was also a cannon, but this one was much larger than the one on the city wall, only two or three in size.

What Di Ping noticed was that on the top of the main tower of his city there was a cannon that was bigger than the watchtower. The mysterious dim light is located at the top of the main tower of the city, like a ferocious beast entrenched there, staring into the distance.

Di Ping was a little excited to see these strange artillery-like weapons, which was his city finally had the ability to defend.

He looked at the interface excitedly, and sure enough, there was a button next to the "first-level city defense function". He clicked it directly, and he wanted to see what the first-level city defense contained.

There is not much content in it, one is a function introduction.

The first-level city defense consists of an all-round intelligent defense a1 energy cannon every 30 meters of the city wall. There are a total of 400 energy cannons. The minimum energy consumption of each cannon is 1 crystal coin, and the maximum consumption is 5 crystal coins. Mutated animals of the first to third order.

When he saw this, Di Ping's scalp was numb. This is a gun. This is money. Grandma's. He has only 80 crystal coins left after building the city wall, which is not enough for a full salvo. This The round is 400 crystal coins, which is still the minimum consumption, and he feels a headache listening to it.

This one has a cannon, but he feels he can't use it!

However, seeing the power introduced later, he felt that it was worth the money.

The lowest energy can destroy the mutant animals in the first-order level, and the highest energy can cause a threat to the mutant animals in the first-order and third-level. If a shot can kill the mutant animals in the first-order and third-level, it can be recovered cost too.
