This wasn't the end of it. Immediately afterwards, all the mechanical parts of the technology tree lit up, and a new line of prompts appeared:

Congratulations on upgrading all mechanical technologies to intermediate (level 4) technology. You have obtained a new blueprint: [Universal Repair Robot]

Looking at the prompt, Chen Wangping's eyes lit up, and he first clicked on the drawing of the universal maintenance robot to check it out.

The maintenance robots in the previous base were not system blueprints, and their repair speed was only average. Moreover, their durability dropped very quickly, and they had to repair each other frequently before they could be put back to work.

You repair me, I repair you, but after we finish repairing, neither of us is very durable.

【Universal maintenance robot】

【Purpose: Repair any system equipment】

Materials: Titanium Plate x 10, Processor x 5, Steel Plate x 10, Magnet x 10, Battery x 20, Charcoal x 20

[Building method: Level 2 manufacturing platform]

[Note: The universal maintenance robot consumes a lot of power, but is very efficient]

"You actually need titanium plates? Luckily, we found some in Fangshan Town."

"But what is this charcoal used for?"

Chen Wangping didn't think much about it, took out the materials, put them on the manufacturing table, and directly chose to forge them.

[Universal maintenance robot is being built, estimated to take one hour]

During this time, he took a look at the drawings of the collection series.

First, open the garbage collector and check it out:

【Garbage Cleaner】

[Purpose: Deep cleaning of garbage in the territory]

Materials: [Animal Hair] × 50, [IC] × 20, [Steel] × 20, [Magnet] × 5, [Battery] × 20

【Note: Garbage cleaning machines can reduce manpower】

Chen Wangping looked at the material of this thing, animal hair, magnet?

Quite interesting.

Two construction tasks were also arranged, and the time was also one hour.

Except for the garbage cleaner, the rest of the drawings are upgraded versions of the old drawings, and the added materials are also similar, such as steel plates and circuit boards. You can directly arrange the corresponding manufacturing table to upgrade the drawings for use.

However, as a result, the number of steel plates could not keep up and a gap appeared.

Chen Wangping walked to the refining furnace and found that the armor that the fire hammer had hammered out had been refined. In the end, five steel plates with a mixture of blue and purple were refined:

【Insulated steel plate☆☆】

【Purpose: Reduce lightning damage】

[Special Effect - Moderate Insulation: Improves the insulation performance of equipment by up to 40% based on the amount added during crafting.]

[Special Effect - Stable Strength: Through refining, the metal properties of this steel plate are largely retained, and the strength remains high]

[Note: Steel with added rare tree bark has both insulation and strength properties]

Weighing the brand new insulating steel plate, Chen Wangping thought it was very interesting.

Although its insulation performance is not as good as that of natural rubber, it is a metal material after all. Having 40% insulation is already very good.

Where does their strength lie?

After thinking about it, he decided to use this material to build another land battle tank. In total, he would have three land battle tanks at home: a frost land battle tank, an ordinary land battle tank, and an insulated land battle tank, which would have extremely strong combat effectiveness.

After arranging the tasks, Chen Wangping saw that it was getting dark, so he simply waited until tomorrow morning to go to Leilong City to sort out the situation.

"Whoosh!"

The cold north wind was blowing, and everywhere except the base was freezing. Today was already the coldest time of the winter. In the previous life, it would have been the coldest days of the year. After this cold period, it would gradually warm up.

Looking in the direction of Leilong City, Chen Wangping had an idea in mind.

If the people from the Insect God Cult take action, it will probably happen in the next few days.

It's time to fight.

Waited for a while.

Chen Wangping first ran to the manufacturing platform of the molten copper in the center of the earth, hoping to take it down.

The two speed plug-ins built this time are all the fiery red of molten copper in the earth's core, which looks very strange.

[Geocentric Velocity Plugin]

【Purpose: Improve production efficiency】

[Special Effect - Geocentric Annual Ring: After inserting into the slot, it increases the production speed of the device by 100% but increases the power consumption of the device by 50% (each device can install up to two similar plug-ins)]

[Special State - Geocentric Acceleration: Entering the Geocentric Acceleration state will increase the device's production speed by up to 300% and power consumption by 150%, consuming all of the device's durability.]

[Durability: 5000/5000]

[Note: Due to the special nature of the plug-in, geocentric acceleration will not affect the plug-in's durability.]

It actually worked.

Production speed is doubled, while electricity consumption is only increased by half.

Good stuff.

And according to the notes, there should be a lot of this core molten copper underground. When I have time, I will dig it up. Then the territory manufacturing speed will take off.

etc.

Geocentric acceleration consumes durability, right?

What if it is combined with a universal maintenance robot?

Chen Wangping looked at the technology tree and smiled.

It seems that it won’t be long before production technology can be upgraded.

He walked over to the universal maintenance robot manufacturing station and took it down.

The universal maintenance robot looks like a black ball, a little silly.

Chen Wangping took a look at the properties and didn't see anything special, except that it had a very high power, a full 60 kilowatts.

He simply plugged in the power and turned it on.

After plugging in the power, the universal maintenance robot suddenly lit up and displayed a prompt:

【Charging】

Chen Wangping was about to go and see what was happening when a line of prompts popped up on the little thing:

[Poor air quality detected at base, activation of purification mode]

Then it suddenly began to deform. Two legs grew out of it as a base, and four fans emerged from its head and began to spin rapidly.

The original control of the base enters its body through the fan, is purified by charcoal, and becomes clean air when it comes out.

Chen Wangping smiled with satisfaction, "This little thing is pretty good. It turns out that it can even repair the air."

He planned to charge it first, so he walked over to the garbage collector and took it down to check.

The appearance of the garbage cleaner looks similar to a garbage truck. It has many brushes made of animal hair on the bottom, a water tank on the top, and some magnetic plates on the side to absorb parts that have fallen on the ground. It also has two robotic arms that can automatically remove some stubborn stains.

Compared with the universal maintenance robot, its power is lower, only 50 kilowatts.

After being connected to the power grid, the garbage collector started to hum and scrape around. It didn't run fast, but it cleaned very well, sucking up all the dust on the concrete. It also had a grinding function, making the ground reflective.

Soon, the garbage collector circled the base, and the entire base became brand new. Coupled with the air purification of the maintenance robot, the base became extremely livable.
