Spellcasting is a permanent addition and my skills are all forbidden spells.

"Energy aggregation device?"

Lu Cheng raised his eyebrows.

This kind of device is not uncommon and can be found in many technological relics.

The effect of increasing skill damage is just an added bonus. The main function of this device is to assist in gathering energy to facilitate processing.

From this point of view, it is more likely that the goods being produced by the production nodes are energy crystal blocks!

Thinking of this, Lu Cheng raised his eyes and looked around.

Sure enough, in the middle of the room, next to three adjacent assembly lines, there was a huge mechanical building in the shape of a tent, flashing with light.

It's the energy aggregation device!

There are only three polymerizable devices, so what are the remaining production lines producing?

Just as Lu Cheng was thinking about it, dozens of production robots were already surrounding him.

"Discover production materials, discover production materials..."

Many production robots gathered around and approached with their robotic arms waving.

"Why are there so few materials sent?"

Seeing Lu Cheng's hands empty, a pair of mechanical eyes lit up red, seeming to be angry.

"Um?"

Lu Cheng's heart moved.

This batch of production robots was different from the ones he had encountered before. The intelligent programs seemed to be a little more advanced.

Moreover, being in the production node all the time does not necessarily cause confusion in instructions.

Then let the metal flower spirit extract it, will there be any gains?

Thinking in his mind, he took out his staff, raised his hand and fired a wind blade.

"Whoosh! Whoosh!"

This wind blade triggered a triple cast, and the three wind blades cut across and cut off a robot.

In a few moments, all these monsters were killed.

"Master, I'm out!"

The metal flower spirit was familiar with the road, and without Lu Cheng's instructions, he stepped forward to retrieve it as soon as his wings fluttered.

After two evolutions, her extraction was much faster, and soon a brilliance lit up between her hands, sharing a stream of information back.

After checking, Lu Cheng nodded slightly.

There is indeed no confusion in the logs of this batch of production robots!

…

[Body type: Zone A production robot]

[Working area: Machine workshop No. 3, Zone A, production line No. 10. 】

【Run log】

[Departed from the factory in 5696, current instruction 1: go to the working area, instruction 2: process raw flesh and blood. 】

[January 5696: Arrive at the operation area and execute the instructions. 】

[February 5696: Execution of instructions. 】

…

Processing raw flesh and blood?

Lu Cheng's heart moved.

No wonder these production robots reacted that way when they encountered him.

It can synthesize energy crystal blocks, which obviously does not require flesh and blood.

In other words, is this production line involving flesh and blood producing something else?

Thinking in his mind, he continued to look down.

The content of subsequent logs is nothing special. It has been executing instructions for decades.

It wasn't until 5725 that changes occurred.

…

[January 5725: An overload module is installed, the loading time is 1 year, and the command is changed to: full speed processing. 】

…

"Overload module?"

Looking over, Lu Cheng raised his eyebrows.

In the Mimic AI log, the output in 5725 increased dramatically, which may be related to this.

While his mind was spinning, he quickly browsed and read several other diaries as well.

These production robots have a very detailed division of labor, and the tasks they are responsible for vary greatly.

However, one thing is consistent.

That is, at the beginning of 5725, overload modules were installed uniformly and production began to be accelerated.

Among them, one production robot was delayed and was only loaded in February.

As a result, the overload module loaded on that robot was due in November and also expired at the end of the year.

In other words, the expiration time of all overloaded modules is exactly the time when the logs begin to break!

Is it a coincidence or is there any connection?

Lu Cheng thought in his mind and glanced at the production lines.

The answer is probably found in these production lines.

With this in mind, he recalled the metal flower spirit and walked towards the nearest production line.

Near the production line, there were sporadic production robots in standby state. As he approached, one by one entered the activation state and approached.

"Leave it to you." Lu Cheng pointed to the production line.

"Don't worry, Master, I promise to complete the mission!"

The metal flower spirit responded quickly and flapped its wings and flew towards the production line.

Watching the metal flower spirit fly away, Lu Cheng raised his staff and fired a few fireballs, blasting away the surrounding robots.

Then, he started thinking.

These production robots contributed more than ten soul fragments to him.

As of now, there are only more than a hundred pieces left to unlock the soul hotbed.

When the time comes, you can find out!

I wonder what kind of soul is contained in this?

Thinking in his mind, Lu Cheng had some expectations.

In front, the metal flower spirit's hands were flying, constantly extracting.

"Master, these three production lines are together, I can extract the information inside together!"

As the metal flower spirit spoke, light already lit up in his palms.

"Um."

Lu Cheng responded, looking aside.

Next to these three production lines, three tent-shaped energy aggregation devices flashed with electric light.

…

【Energy Aggregation Device (Small)】

【Special building】

[Durability: 30 million/30 million]

[It can aggregate surrounding energy and reduce energy loss. When activated, it can provide energy for specific buildings. 】

…

Looking over, Lu Cheng's heart moved.

There is no information recorded in this device, but there is no need to extract it.

but……

This device is not only found in ruins, but can also be built in the city if there are blueprints.

There are three energy aggregation devices here. I wonder if they can produce a blueprint?

Although it is not of use now, it will come in handy when it is upgraded to a city!

Thinking of this, Lu Cheng raised his staff.

"Bang!"

-

192384!

A fireball fell, and the energy aggregation device trembled with electricity.

He cast spells one after another, and after a while, the durability of this energy aggregation device reached its limit.

"Boom boom..."

There was an explosion sound inside the energy aggregation device and it began to disintegrate, followed by a system prompt.

[Ding, you destroyed the energy aggregation device (small) and gained +8 million experience points! 】

Listening to the system prompts, Lu Cheng's lips raised.

The experience provided by the energy aggregation device is so rich?

This was an unexpected surprise.

Now, he is only 15 million experience away from being upgraded.

Destroy the other two devices to reach level 37!

Thinking in his mind, he waved his staff continuously.

Soon, the second energy aggregation device also collapsed.

Although no blueprints were released, it still provided 8 million experience points.

Lu Cheng held the staff and found the third device.

As soon as the spell fell, the third device was also permanently cleared.

When it collapsed, it brought out a flash of light!

"Yes."

Looking at the flash, Lu Cheng's eyes lit up.

At the same time, a system prompt came to his ear.

[Ding, you have reached level 37 and gained +90 health, +90 mana, +9 all attributes, and +60 free attribute points! 】

Lu Cheng felt comfortable bathing in the brilliance of the upgrade.

Then, he looked at the flash.

That flash of light was exactly a drawing!

…

[Architectural drawings: Energy polymerization device]

【Special building】

[It can only be built in the city, occupying building slot 1, and a single drawing can be built 3 times. 】

[Each energy aggregation device can increase the feedback from houses by 10%, increase the effect of energy buildings by 5%, and increase the damage of energy skills by 1%. 】

[If there is a miracle building in the city, the increase effect will be doubled. 】

[Materials required: Fine iron x500, metal plate x100, energy source stone x1...]

…

Putting away the drawings, Lu Cheng felt satisfied.

Although the individual effects of these special buildings may not seem high, when combined, they have a considerable impact on the strength of the city.

Being able to get the blueprints is also a good reward!

Just as he was thinking about it, on the other side, the metal flower spirit was also extracted.

After sharing, the log information of these three production lines suddenly appeared in his field of vision.
