He slapped himself on the head and exclaimed, "Oops, how did I forget that thing!" With that, you don't have to be afraid of zombies! ”

Some people may have guessed that the "it" that Ye Bing was referring to was the reconnaissance robot that Natasha had mentioned!

At the beginning, the unit recommended by Natasha to attract zombies was the reconnaissance robot, but later because it could not be built, Ye Bing volunteered to act as a human bait, but now, the situation is different from before. The biggest difference is, of course, the difference in capital!

Don't forget, he still has 11 units of energy in his base, ready to use. As long as you use this energy, build a mechanical barracks, and create a few teams of scout robots to attract firepower, do you still need to worry about the siege of zombies?

Ye Bing pondered for a while, and the more he thought about it, the more he felt that this plan was feasible, so he didn't hesitate much, adjusted the large screen interface to the construction interface again, and pointed his finger towards the icon of the mechanical barracks.

Immediately, three lines of familiar small words popped up from the screen:

"Construction cost: 10 energy cost."

"Build time: 5 minutes."

"Do you confirm the build?"

Ye Bing replied decisively: "Confirm the construction." ”

After choosing a construction site, a ball of white light rose from the side of the base, spinning violently and rapidly in a form visible to the naked eye!

Five minutes later, as the light gradually dissipated, the construction of the mechanical barracks was completed on time, revealing the exquisite and magnificent structure within, which was the form of the mechanical barracks LV1!

At the same time, Ye Bing looked at the message panel and found two messages on it:

"The construction of the mechanical barracks LV1 has been completed!"

"The main base has gained 3 points, and the cumulative points are 7."

In fact, these two prompt messages appear every time a building is completed, but every time Ye Bing can't wait to run out to take a closer look, he doesn't notice these two pieces of information.

Through the latter piece of information, Ye Bing gradually sorted out a rule, it seems that the more energy spent on the building, the longer it will take to build, and the more points will be harvested. If you want to increase your points as quickly as possible, you can choose more expensive buildings, and of course, this premise should also be based on a meaningful foundation. Something like the terrain transformation platform is not very useful at this stage, even if it provides more points, Ye Bing will not choose to build it in a short time.

However, as of now, the total points of the base have reached 7 points, and Natasha still hasn't given him any news that he can upgrade the main base, and he doesn't tell him directly. But I don't know how many points I need to upgrade my main base? This Ye Bing is still looking forward to it.

After savoring the extremely mechanical-style appearance of the mechanical barracks through the transparent protective film, Ye Bing returned his attention to the big screen, because from there Ye Bing found a submenu, which was the subordinate construction menu of the mechanical barracks, so he clicked on it without hesitation.

Sure enough, after entering the submenu, Ye Bing saw a series of construction icons, but most of them were all black and invisible, and they could not be unlocked until the mechanical barracks was upgraded to a higher level. In addition, the current basic stats of the Mecha Barracks are as follows:

Name: Mecha Barracks

Building Class: LV1

Health: 220

Production speed: Slow

However, among the few classes that can be built in the mechanical barracks, Ye Bing found the class he had been waiting for a long time - reconnaissance robots!

Ye Bing excitedly clicked on the reconnaissance robot, and the large screen immediately switched to its detailed attributes:

Class: Scout Robot

Grade: LV1

Health: 10

Volume: Very small

Movement speed: 0~10 m/s

Colonization Technology: None

Occupation limit: 0.5 units

Production cost: 1 energy cost

Production time: 5 minutes

Notes: This is a robot designed for scouting environments, with its small size and heat-resistant materials allowing it to climb over a variety of terrains. Be careful, however, that when Scout Robots move quickly, they will always attract unnecessary hatred from other creatures, so be cautious about using this.

Ye Bing observed it with great interest, especially the last point that attracted its attention. He was still thinking about how to make the zombies interested in this group of little robots, but now it seems that he doesn't need to think about it. As long as you control them to move at high speeds, the zombies will naturally chase after them.

However, there is a real problem at hand, and that is...... How do you order the Scout Robots to act?

When Ye Bing asked this question, Natasha's answer was this:

"Commander, you have a base core synchronizer in your body, and within a certain range, you can completely control the activities of all units through your mind."

Ye Bing nodded when he heard this. Although he didn't know what Natasha's synchronizer was, he understood how to control the robots, which was to put it bluntly, "think", and rely on his mind to control it. This kind of thing that usually only belongs to the science fiction level actually happens to me, and it still feels quite amazing.

Before building the reconnaissance robot, Ye Bing took a closer look at several other types of troops that could be produced, namely jet soldiers, military soldiers, mechanized engineers, and medical mechanics. He briefly looked at the introduction of each class, and found that the first two were actually combat classes, the difference being that one was long-range and the other was short-range. The latter two are support classes, the former for building faster buildings and doing some manual work, and the latter for repairing other damaged mechanical classes.

Looking at the two combat types of mechanical soldiers, Ye Bing's eyes couldn't help but heat up for a while. He had always wanted to build a few more beam towers, but he couldn't increase them due to the limitations of the base, but now, if he had a combat class, wouldn't it be able to play the same role as the beam towers?

Thinking of this, Ye Bing involuntarily clicked into the detailed data of one of the troops, and when he saw the item "production cost", he couldn't help frowning.

"Alas...... The price of these soldiers is really expensive......"

He sighed and shook his head helplessly. He then clicked in and looked at the other classes, only to find that in addition to the Scout Robot, the production cost of the rest of the classes was at least 2 energy, and the more expensive ones cost 3 points, even more than the price of an LV1 beam tower.

However, these are not the main ones. The reason why Ye Bing couldn't choose them was that he had no energy in his hands.

Looking at the pitiful 1 point of energy left in the base, Ye Bing still honestly returned to the submenu and clicked towards the icon of the reconnaissance robot!
