After seeing this scene, Ye Bing was completely stupid!

Such a large piece of metal shell is said to disappear and disappear? It's amazing!

Curious, he ran to the edge of the base, and with a tentative poke of his hand, he touched a transparent film, which seemed to have the same texture as the plastic wrap sold in the supermarket. Moreover, as the strength of Ye Bing's fingers increased, the film would expand outward, so frightened that Ye Bing hurriedly withdrew his fingers, for fear that it would be bad if he accidentally poked and leaked!

If it was put in the past, Ye Bing would not have been so cautious, but after experiencing the "protective film rupture" incident, he didn't dare to be careless no matter what!

However, just as Ye Bing had just retracted his fingers, his gaze happened to see some ...... not far away through the membrane No, it should be said that it is a certain group......

Zombie!

At first he only scanned one or two by accident, but when he completely turned his attention away, he was completely stupefied!

He looked around and found in disbelief that at this moment, he and his base seemed to be in some kind of zombie sea, and the number of zombies around him must reach at least thousands!

"Natasha, hurry up and restore the shell to !!" Ye Bing almost roared and gave the order.

With a slight jolt, the liquid metal "crawled" back to its original position at a speed visible to the naked eye, and the entire base changed from a "bare" state to a closed form.

As Ye Bing continued to comfort his poor little heart that was so frightened that his heart rate instantly jumped to 150, Natasha's calm voice once again lingered throughout the base.

"Commander, seriously, you don't have to be so alarmed at all. Even if the base shell is fully transparent, the inside of the base cannot be seen from the outside, as the visual effect is one-way. ”

"I'm dizzy, why didn't you say it earlier! I was almost scared to death! ”

Ye Bing patted his chest helplessly. Suddenly, as if he remembered something, he cried out:

"That's not right! Zombie hunting isn't just based on sight, a big part of it is based on smell! Even if the base shell can block their view, they will soon find it by following the smell! ”

In the face of Ye Bing's worries, Natasha only replied lightly: "You don't need to worry, these worries have been solved at the beginning of the birth of the base. Now, above our heads, within a radius of ten meters centered on the base, a first-class shielded magnetic field capable of not only disrupting the vision of the creatures outside, but also directing them to produce false sense of hearing and smell. As soon as the zombies get close, they will immediately feel disgusted and dispersed. ”

As soon as he heard this, Ye Bing was also happy. He smiled and asked, "Zombies don't even feel pain, so they still have disgust?" ”

"Yes. Biological pheromones still operate within them, but in a very different way than they did in humans. Natasha replied.

Ye Bing asked: "Then what if, there are one or two zombies, they just walk into the shielded area without opening their eyes?" ”

"Once you enter the shielded area, everything is automatically deactivated, including sight, hearing and smell. Zombies will attack the base. Natasha replied without any delay.

Hearing this, Ye Bing nodded with a heavy face. As far as the current situation is concerned, it is not a problem to walk into a few zombies by chance, but once the second mutation breaks out and the zombies officially enter the first order from the elementary level, things will not be easy to handle. At that time, just take out an ordinary zombie and be enough for Ye Bing to drink a pot, let alone be besieged by more than two.

Fortunately, Ye Bing also knew in his heart that there were still more than twenty days left, and he would not make no progress. What's more, such a high-tech base will not only have that much ability, right?

Thinking of this, Ye Bing raised his head and said, "Natasha, you can continue to talk." ”

"Okay." Natasha replied.

"The above is the basic function of the base, and what I will tell you next is the construction function of the base."

After Natasha finished speaking, the big screen in front of Ye Bing suddenly changed again, becoming a different scene!

It's an interface that is both image and text. At the top of the screen, there are four large characters that say "Construction Interface", and below them are a variety of buildings that look extremely interesting. However, Ye Bing also found that except for the top few buildings, which are green, most of the buildings are gray, and the words "not buildable" are marked next to them.

In addition, Ye Bing also saw that next to each building in the allowed construction state, the cost of building the building will be displayed, for example, a building named "Technology Tree" is displayed next to "5 Energy Cost", and the font color is red, which means that even if the base level allows construction, but because of insufficient energy, it cannot choose to build the building.

But what made Ye Bing extremely excited was that next to one of the buildings called "Beam Tower", what was displayed was a line of small green letters, which read:

0 Energy Cost!

Does that mean he can build it for free?

When Ye Bing asked this question, he got an affirmative answer from Natasha.

"Yes. In order to ensure the safety of the commander in the early stage, the base has specially reserved the energy of a beam tower for you, and this energy can only be used to build a beam tower and cannot be used for other buildings. ”

Ye Bing smiled, he didn't expect that this doomsday base was quite humane, and even the security of the host in the early stage was taken into account. It just so happened that Ye Bing's original crossbow was also lost in the process of teleportation, and if there was no defensive building, it would be really difficult to solve it once a zombie broke in!

Natasha's voice asked, "I suggest you choose to build a beam tower as soon as possible to keep you safe. ”

"Okay, then hurry up and build one! But what do I do? Ye Bing asked.

"All you need to do is tap the beam tower icon and follow the prompts."

"Well, I'll try."

Ye Bing walked to the big screen, and without hesitation, he immediately reached out and poked straight towards the icon of the beam tower!

At the moment when Ye Bing poked at the beam tower, all the other building icons around him disappeared, only the icon of the beam tower was enlarged and moved to Ye Bing's eyes, and there were three lines of prompts written next to it, namely:

"Construction Cost: 0 Energy Cost."

"Build time: 3 seconds."

"Do you confirm the build?"

Ye Bing was stunned, and poked the "yes" button again.

Just as he had done all this, the screen changed again, only this time it was a bird's-eye view!
