Yes, what flashed in Ye Bing's mind at this time was the terrain transformation platform!

Since it's hard to walk on land, can you get around the ground?

If this was put in the past, Ye Bing didn't even think about it, this kind of big project, even if a professional construction bureau came to do it, it would take a few years.

But once you have a base, it's different!

Don't forget, the base is completely digital!

As long as you put in the energy, even a huge building can be made out of thin air for you to see!

In addition, the digital radius of the base has now been expanded to 60 meters, and if a passage can be created underground for troops to walk freely, wouldn't all problems be solved?

Thinking of this, his heart couldn't help but get excited.

However, when he thought of the energy required to build the terrain transformation platform, Ye Bing once again made a bitter face.

He sighed and muttered:

"Alas, it's better to keep a mentality for the time being, no one can eat a fat man in one bite, as long as you go step by step, there will always be a successful day."

After figuring it out, Ye Bing shook his hand and continued his daily work.

That night, Ye Bing paid the price of 5 energy to upgrade the solar crystal panels from the tech tree. Since then, the number of natural daily energy increases at the base has increased from 1 to 5.

In the afternoon of the next day, after more than half a day of fatigue and cleaning up hundreds of zombies, the number of energy stored in the base finally managed to exceed 20, and Ye Bing also chose to upgrade the material recovery tower for the first time!

This is the first building that Ye Bing upgraded after the main base level reached LV2, and it took a total of 30 minutes.

As the light in the sky dissipated, an even larger material recovery tower appeared in the base's territory!

Ye Bing couldn't wait to open the interface of the Matter Recovery Tower to check its changed properties:

Name: Substance Recovery Tower

Building Class: LV2

Health: 200

Energy recovery: 50%

Number of recovery carts: 0/1

It can be clearly seen that the HP of the Matter Recovery Tower at the LV2 level has not increased much compared to the previous level, but this is not a major attribute for it. Most importantly, the energy recovery rate has increased from 40% to 50%, which is equivalent to a direct increase in efficiency by a quarter. Zombies that could only recover 40 energy points can recover 50 energy points in the future, which is definitely a crucial step in the long run!

In addition, Ye Bing also saw an extra content on the attribute panel:

Recycling carts!

"Natasha, what is this recycling truck for?!"

Although he had already guessed eight or nine points in his heart, in order to be safe, he still opened his mouth to ask.

"The recycling cart is a continuation of the material recovery tower, which is able to suck recyclable objects into the cylinder and crush, compress them, etc. The primary recycling cart does not have the function of energy conversion, and can only be used for semi-processing of recycled objects. If you need to get all the features, you need to upgrade them to a higher level. Can be built in the mechanical barracks. ”

After listening to Natasha's introduction, Ye Bing snapped his fingers excitedly on the spot.

That's right, that's it!

Originally, he was still worried about how to get back after killing so many zombies outside in the future. If you have to prepare your own truck, it is not convenient enough, and you can't carry many corpses at a time. With the recycling cart, none of this will be a problem.

Then, he jumps to the mechanical barracks interface, and finds that a new type of unit, the Recovery Vehicle, has been unlocked.

Class: Recovery Cart

Grade: LV1

Health: 50

Volume: Medium

Movement speed: 0~150km/h

Track armor: None

Colonization Technology: None

Occupation limit: 1 unit

Cost of production: 5 energy cost

Production time: 10 minutes

Ye Bing glanced at the data of the recycling vehicle slightly, and when he saw the production expenses, he couldn't help but roll his eyes.

Damn, this thing costs 5 more energy.

Well, it looks like there's no other way to go than to work energy.

In this way, under the condition of insufficient demand from many parties, Ye Bing could only bury his head and continue to deal with zombies hard.

Fortunately, thanks to the upgrading of the material recovery tower and solar crystal panels, the speed of energy acquisition has gradually begun to skyrocket.

In total, the energy obtained by cleaning up zombies every day has increased to about 20, and with the 5 energy points stabilized from the solar crystal panels, the average energy can increase by 25 points a day!

Compared to the previous 10 energy points per day, this is almost a leap forward!

So, on the fifth day after returning to the base, Ye Bing finally set up a terrain transformation platform!

"Can this thing really be used to modify the terrain, why do I feel like I'm being played......

At this moment, Ye Bing was sitting in front of the base master console, but he was holding a remote control with a joystick in his hand......

If it weren't for the fact that this thing was really produced from the base, he would never believe that this guy alone could transform the terrain!

Well, in fact, along with the little remote control, there is a new steel building outside, which looks like it should be the main body of the terraforming table. But making the remote control so XBOX-like has a sense of déjà vu makes people a little laughable.

Okay, but since it's a product of the base, let's try it with it, so you won't even be pitted against your own people!

Ye Bing smiled helplessly and ordered Natasha to open the interface to the terraforming interface.

"Hey, it's really, it looks realistic!"

Looking at the picture that popped up on the screen in front of him, Ye Bing couldn't help but be taken aback.

It turned out that what appeared on the screen was a three-dimensional bird's-eye view of the base, but it was not exactly the real scene, with a certain degree of animation style, and some lines overlapped with each other where the pixel wind could be seen.

THIS INTERFACE LOOKS QUITE SIMILAR TO A GAME CALLED MINECRAFT THAT YE BING KNEW BEFORE, BUT BOTH THE GRAPHICS AND THE SMOOTHNESS OF THE ANIMATION ARE MUCH MORE BEAUTIFUL THAN THE LATTER.

Ye Bing manipulated the remote control and experimented for a while, and quickly mastered the usage.

The joystick on the left side of the remote control can control the screen to move forward, backward, left, right, and up and down, and a series of buttons on the right are used to lock the cardinal point, eliminate, add and other additional functions, which is easy and practical to use.

After learning how to control it, Ye Bing moved the screen to an open space next to the base.

It first drew a square in the open space, then set the thickness, and finally pressed the eliminate button!

I saw that at the moment he pressed the button, the selected area was suddenly shrouded in a cloud of white light, and after less than a second, the light cluster disappeared, leaving only a rectangular gap in place, and the section was as smooth as a mirror!

If there are sophisticated people who are willing to measure it with a ruler at this time, they will definitely find that the missing side length of the cuboid is exactly the same as the one set by Ye Bing before, and there is not even an error of half a millimeter!
