Thinking of this, for some reason, Ye Bing's mind actually appeared in the tower defense game scene he had played in the past!

The so-called tower defense game is a game in which players destroy waves of monsters by building and placing defense towers reasonably.

In most tower defense games, the monster's goal is to attack the player's base camp, and in order to do so, you need to walk a narrow path. Players can build a variety of towers on both sides of the road to destroy monsters and stop them from invading their base camp.

Although this is only a setting in the game, according to Ye Bing's vision, it may not be impossible to turn it into reality.

Although the zombies didn't know where Ye Bing's base camp was, as long as they sent a few scout robots to attract them in front, wouldn't they be able to command them in any direction!

As for how to make zombies only walk in a straight line and not go around a corner, it is also very easy to solve.

Wouldn't it be enough to give them one way to go?

Dig an underground ravine to get out. Once the zombie enters the ravine, there are walls on the left and right, so naturally they can only walk in a straight line!

After that, the towers are moved to the top of the ravine. Towers can hit zombies, but zombies can't hit towers, so you can be truly harmless.

Well, perfect!

The more Ye Bing thought about it, the more excited he became.

Although the zombies on the outer layer of the base are more important in protecting the base, in order to develop in a short period of time, they can still kill some and accumulate some energy. The most important thing is that Ye Bing now needs the magic crystals in their brains, and they need it very much!

However, when Ye Bing opened the interface of the terropographic transformation platform and was really faced with the actual operation, he suddenly made a difficulty.

"What the hell are you going to do with this......"

He scratched his head with a headache and muttered.

You know, the terraforming console's interface is quite rigorous. I want to make an arc. You have to determine the center and radius of the circle first, and if you want to dig a hole, you have to give a datum first, which is not something that can be done by just thinking about it.

Otherwise, he wouldn't have spent an entire day just digging a tunnel.

He looked up at the sky blankly for a moment, and an idea suddenly popped into his mind!

"Natasha, I'll give you some advice, can you help me design the terrain?"

He looked up and asked with interest.

Natasha's crisp voice sounded from above for the first time:

"I will take care of everything you need. Commander, but when the data is not sufficient, the brain cannot guarantee how far the actual effect will be from your intended goal. ”

Ye Bing bit his lip and made up his mind:

"It's okay! As long as you can do it, it's better than what you can't! ”

He was right. If it were up to him to do it himself, it was estimated that he would not be able to come out of the prototype in five days.

"Understood. Say what you want, Commander. ”

Ye Bing thought carefully for a while, and then told Natasha all the requirements he could think of.

Among them, the main one is the setting of the tower defense game in memory. Several important placements for defense towers, as well as ensuring the security of the main base in any case.

He almost thought of where to go, for fear of missing out on useful information, and ended up saying a bunch of nonsense. I don't know how much Natasha understood.

"Understood. That's all there is to it, Commander? ”

Ye Bing thought about it again, and suddenly another idea came into his mind!

"Ah, yes...... Natasha. You see, it's not going to work. Let's only set the outermost area of the protective circle as the offensive and defensive area, so that the zombies can go back and forth freely in the ravine, and the inner area is set as the core area. How about digging a three-meter-long, five-meter-deep circular lake between the two areas as a separation zone? ”

Natasha was silent for a moment, then replied:

"If you want to dig a three-metre lake, you first have to make sure that you have a two-metre thick mound on each side to support it, otherwise the lake will break down the ground and sink into the ravine."

"Oh yes, there's such a rigid need that I overlooked. However, the total area of the annular mound is more than two meters thick, so why not add some other materials to the terraforming table? For example, reinforced concrete? Ye Bing asked in confusion.

Natasha quickly replied:

"The range of materials used in the terraforming table depends on the site's digital storage. To put it simply, you must have entered the material before you can use it in the terraforming table. When you want to build reinforced concrete fortifications, you have to collect the reinforced concrete into a compression equipment such as a recycling truck, pour it into a material recovery tower, and finally turn it into a digital storage that can be used in the terraforming platform. ”

After listening to Natasha's explanation, Ye Bing finally understood.

It turns out that the material recovery tower still has this function, but he has always thought that he can only use zombie corpses.

But in this case, it will be necessary to go out with the recycling truck in the future, smash some houses, and get some cement back.

Until then, do as Natasha suggests.

So, Ye Bing nodded and said:

"No problem, just do as you say......"

However, in the middle of his words, he suddenly thought:

"Wait! That, how long does it take to complete these things? And we need water to build a lake, so much water, where do we get it? ”

Natasha replied lightly: "The problem of the lake, the base can pump groundwater and disinfect to solve it, but the speed is relatively slow, according to the current climate and humidity, it will take about two months." Of course, there are faster ways to do it, but it requires a certain amount of energy. ”

As soon as he mentioned the consumption of energy, Ye Bing subconsciously felt a pain in his flesh, but he still endured the pain in his heart and said:

"How much energy, you can say."

"1 energy spent per day."

"1 energy spent per day?!"

Ye Bing exclaimed, he almost thought he had heard it wrong.

Seeing that Natasha was called by him like this and there was no follow-up, Ye Bing couldn't help but sneer: "Uh, it's okay, you continue to ......"

"With a little energy consumed every day, the base can greatly increase the centrifugal force of the pump, and it only takes two days to fill the artificial lake. In addition, the terraforming takes about two hours in total. Do you want to get started right away? ”

Ye Bing was stunned by Natasha's words, and nodded when he said:

"Oh, let's get started."

As soon as he finished speaking, he saw a large ring of light appear outside, which was the sign of the start of work on the terraforming platform!

In his gaze, one after another clusters of light alternately appeared in the protective circle. Whenever a ball of light dissipates, there will be a deep and long ravine left, as if a god is erasing it with an eraser, which is very shocking!

As one piece of land after another was dug up, it didn't take long for the general shape of the attack and defense area and the artificial lake to be created! (To be continued.) )
