I have to say that the effect of the musculoskeletal plaster is quite obvious.

Although it was only the most rudimentary LV1 musculoskeletal plaster, after Ye Bing applied it, it only took an hour for the pain to basically disappear. As long as you don't deliberately tap the injured area, you basically don't feel anything strange except for a hint of coolness.

In addition to the effect of the musculoskeletal paste itself, the injury suffered by Ye Bing itself was not too serious, which was another reason.

If the bones are really shattered into slag, I am afraid that even if the LV3 musculoskeletal paste is applied, it will take several weeks to recover like this.

This phenomenon proves the power of the tights after the reinforcement of the colony, and at the same time makes me realize how important it is to have a good piece of armor.

In the future, if possible, don't miss any chance to improve your armor!

After feeling that his body was almost recovered, Ye Bing sat up from the chair.

It's time to think about what to do next.

He lowered his head, pondered for a moment, and then suddenly raised his head and asked:

"Natasha, let me ask you a few questions. You said before that the simple version of the barrier requires more than 800 points of energy to make it, right? But how long will it take? In addition, if you want to expand the base in the future, can the barrier be expanded and moved along with it? ”

Natasha quickly gave an answer to his question:

"It takes about seventeen hours to build a simple version of the barrier. If you want to expand and move in the future, you will need to pay additional energy, which will fluctuate between 100 and 1,000. ”

"Oh, that's right......"

Ye Bing pinched his chin, this result was still within the range he could accept.

After all, moving such a large piece of the city wall is a big project.

Thinking of this, Ye Bing didn't hesitate and said straightforwardly:

"I've decided to build a simple version of the wall! If you want a location, choose a place that you have thought about in advance. Enclose the entire base data scope in it! ”

Natasha replied, "Understood. ”

In the next second, the number on the energy reserve attribute bar on the big screen suddenly dropped by more than 800 points, and the total energy instantly dropped to 1600!

At the same time, the large screen also jumps to the map interface.

It can be clearly seen that at the edge of the base's digitization range, there is a long white line, enveloping the entire digitization area.

In the future, with the protection of this barrier, there is no need to worry about the attack of zombies or mutant beasts.

Although it is only a simplified barrier, the thickness and material are mixed with a little moisture. It's easy to keep thousands of zombies out of the city.

Of course, in front of those zombie mutants who can climb walls and fly, no matter how high and thick the barrier can be, there is a limit to what it can do.

But after all, the main forces of the zombie army are still the red zombies and Hulk zombies who can't climb the wall, aren't they? As long as you stop them, the rest will not matter.

However, even with this city wall, Ye Bing still couldn't feel at ease.

Because the enemies he has to consider aren't just brainless zombies and mutant beasts.

He pondered for a moment before asking:

"Natasha, if there is an outside force that strikes us in the air. Can we only be beaten passively? ”

He asked because so far he had not seen any effective defense against the air.

It is true that the UFO disc and the fighter have a certain anti-air defense capability. But if the enemy launches several ICBMs from afar. Do you want to send fighter planes to the top?

Obviously impossible.

That's why I asked the question before.

Natasha didn't give an immediate answer to this question.

After waiting for a while, her voice rang out from the air:

"I'm sorry Commander. For the time being, our bases lack effective air interception and protection capabilities, and only have a few passive defense functions. For the case you said. I recommend that you upgrade the following technologies. ”

As he spoke, the picture on the big screen changed again, jumping to the technology tree interface.

In the center of the screen, there are several technological names that Ye Bing hadn't noticed before.

The first technology is called "War Radar". According to the introduction, activating this technology will add a war radar function from the main base, which can detect abnormal movements in a large space around the main base. Once an enemy unit is spotted, it will immediately relay the alarm to the Brain and cooperate with other towers and classes to counterattack.

The second technology is a main base skill, called "Doom Mania", and the effect is to greatly increase the ability of all buildings for a certain period of time. This ability refers to the main function of the building, such as the mechanical barracks, and has the effect of producing units faster. For each tower, the range and damage are greatly increased.

The third technology also belongs to the main base skill, and Ye Bing is not unfamiliar. Its name is "Non-Absolute Force Field Guard", and its effect is also very powerful, which is to support a force field defense network within the data range of the entire base, which has resisted a certain degree of external invasion.

It can be said that each of these three technologies is very powerful.

Take the first war radar as an example, Ye Bing decided that it was an indispensable technology at the first glance.

The price of unlocking this technology is one hundred points of energy, Ye Bing didn't even hesitate, and unlocked it directly.

The detection radius of the war radar of the LV1 class reached 10 km. After unlocking, a circular area suddenly appeared in the upper right corner of the large screen. In the middle of the circular area is the base that Ye Bing is at the moment. In other parts of the circular area, there are some more dense dots, including members of the New Territories forces and zombies outside.

However, looking at this dense circular area, Ye Bing couldn't help frowning.

It's so chaotic that you can't tell the enemy from you at all!

In that case, what's the use?

Just when Ye Bing was feeling depressed, Natasha's hint was given in time:

"Due to the large number of active life forms in the radar area, you can limit the movement speed and volume of the detected object to achieve the purpose of deletion. In addition to this, you can also issue chips to known units, which can also play a different role. ”

"Chips?" Hearing this word, Ye Bing raised his eyebrows.

Natasha replied, "Yes." As an ancillary product of the War Radar, the chip is a free item. ”

Ye Bing thought about it and suddenly swallowed his saliva.

The next second, he asked in a low voice:

"In that case, can I add some other features to the chip?" (To be continued.) )
