[Forget it, we're just starting out now, and a lot of things are unclear, so let's just muddle through for now...]

After the system made this decision, it began to make far-fetched explanations.

[Host, this system is also operating according to regulations. It is really unable to provide additional information...]

Lu Xingchen felt helpless when he heard this. After all, the final right of interpretation was indeed in the hands of the system.

"Forget it, let's finish building the factory first."

After Lu Xingchen finished speaking, the Möbius strip began to shrink gradually, then disintegrated and reassembled into a cylindrical technological product suspended in mid-air.

A Qiang prompted Lu Xingchen to start building the factory.

So Lu Xingchen threw out the second card - a card for building a primary factory with one click.

This card is similar to the previous one, with the same translucent texture and ripples.

The card floated into the air, and the place where the garbage mountain was located had been restored to its previous deep pit.

Just as Lu Xingchen was wondering how to solve this big problem, a small piece of the bottom of the card broke off.

From that small area, a large amount of building materials began to pour out.

Building materials began to pile into the deep pit as if by an invisible hand.

"This card has this function? I was just trying to figure out how to fill this huge hole, but it automatically filled it for me!"

Lu Xingchen said with satisfaction, putting his hands on his hips, but then Aqiang's voice came faintly.

"Master, maybe you think it's a bit simple..."

"What?!"

Lu Xingchen was very confused and prepared to go forward to check.

Just as he took a step, he was unexpectedly stopped by Aqiang.

"Master, if you want to see it, I can take you up there."

Lu Xingchen smiled slightly.

"You have this ability? Brother Tongzi is so secretive, I can't do anything about it. I'm going to give you a good lesson later!"

As soon as he finished speaking, Aqiang changed his form on the spot and turned into a spaceship with a circular cockpit.

Except for one side of the cockpit which is different from the flying saucer, the overall look is somewhat similar to the flying saucer.

"Holy crap, are you a UFO?"

Looking at Aqiang who looked a bit like a flying saucer, Lu Xingchen entered the cockpit cautiously.

With a series of anti-gravity buzzing sounds, Lu Xingchen arrived above the deep pit.

The side of the spacecraft turned completely transparent at this time. Lu Xingchen looked down and couldn't help but gasp.

The bottom of the deep pit expanded further, and a huge amount of titanium metal plates poured out from the card to lay the building structure underneath.

"Are you planning to build an underground factory?"

Upon hearing this, A Qiang silently handed the scan data to Lu Xingchen.

"What! Titanium plates? And they extend down a full 1,000 meters!"

"This system is like a screen door wiping my butt—it slipped through my fingers!"

"I thought the Energy Conversion Terminal was invincible! I didn't expect this card to be even more powerful!"

The construction went very quickly, and soon a comprehensive factory built with titanium metal plates was completed.

Lu Xingchen looked at the overall structure diagram scanned by Aqiang and showed a shocked expression.

The entire factory is underground, with a horizontal area of ​​at least 250,000 square meters. From the top, the factory extends downwards for a full 1,000 meters!

Lu Xingchen was dazzled by what he saw, but suddenly he discovered that there was a space left at the bottom of the factory.

At this time, the energy conversion terminal is still suspended in the air.

"What's going on? If I'm guessing correctly, the energy conversion terminal should be placed inside, right?"

At this time, Aqiang fell silent after hearing this.

Lu Xingchen thought about it carefully and suddenly realized that no matter how much energy there is, it will run out one day.

Now the issue of sustainable development should arise.

At this time, Aqiang reminded that the spacecraft can extend its robotic arm to assist in completing various tasks.

Upon hearing this, Lu Xingchen did not hesitate and immediately started the robotic arm, boldly modifying the energy conversion terminal.

The system had rewarded Lu Xingchen with a first-level energy converter before, and he remembered this.

So I took out the converter from the system interface.

Lu Xingchen's hands-on ability is unquestionable, and he quickly assembled the terminal and converter.

Using a robotic arm to drag the terminal, Lu Xingchen placed the terminal in the space at the bottom of the factory.

Then the converter extended out, and Lu Xingchen split it into two streams, placing them in the factory's waste collection workshop and energy processing center respectively.

As Lu Xingchen pressed the trial run start button, the entire factory let out a low roar like a tiger waking up from sleep!

"Done! The factory expansion was successful!"

"But my brother Tongzi told me that this is just a primary factory. Is he serious?"

Lu Xingchen couldn't calm down for a long time when he looked at such a huge underground factory.

Next, after Lu Xingchen used the "One-click construction of primary technology assembly line" card, the entire factory was completed perfectly.

Processed waste is transferred directly to the energy processing terminal, which provides an almost continuous supply of energy.

The entire factory can be said to produce and sell its own products, and never stops.

After completing the construction of the factory, Lu Xingchen returned to the ground.

"The entire factory is underground, so what should we do with the land above?"

Lu Xingchen looked at the exposed titanium metal plates on the roof of the factory and fell into deep thought.

"Forget it, let's take a look at the factory's incoming and outgoing ports first!"

Lu Xingchen came to the east side of the factory, where there was a huge freight elevator.

If necessary, the raw materials can be unloaded here directly and then transported to the factory.

On the west side is the export workshop, where the products can be transported out.

"This is a bit tricky! The factory is underground, and getting raw materials and goods in and out of the factory is a bit troublesome..."

A Qiang was about to speak at this time, but was suddenly blocked by the system and could not make any sound.

Lu Xingchen was flying in the Aqiang spaceship in the sky thinking about countermeasures.

"Aqiang, do you have enough fuel? I have a bold idea!"

At this time, Aqiang's voice was uncontrolled, and he said that his energy supply system was provided by the system, which was similar to Lu Xingchen's Ark reactor.

"Is it so strong?"

Lu Xingchen was slightly surprised, but after knowing this, he no longer had any concerns.

Then began to take drastic measures.

The top of the factory is more than ten meters away from the ground.

Lu Xingchen began to transplant soil from the surrounding mountains to this place.

After transporting it several times, I found that it was a drop in the bucket.

Because the size of Aqiang's spacecraft is limited, it can only carry a few cubic meters at a time.

At this time, Brother Tongzi finally couldn't bear it anymore.

[Ding! Host, please check for hidden Easter egg rewards.]

【Fill in the land card with one click! 】

[Build simple camouflage and infrastructure cards with one click! ]

Lu Xingchen chuckled when he heard that.

"It has to be you! I knew you had some special skills."

The system was actually helpless. It blocked Aqiang just now because it wanted Lu Xingchen to find a solution himself.

Now Lu Xingchen has figured out a solution, and he has to do this to save time.

Lu Xingchen took out the first card and flicked it gently. The hole from the top of the factory to the ground was immediately filled, emitting the scent of fresh soil after the rain.
