It's reasonable for me to have a two-way foil for a second-level civilization, right?

A few seconds later, two clear responses came from the radio one by one: "Got it!"

……

As time passed bit by bit, the outline of Spirit God Star gradually appeared in front of everyone.

An asteroid with pits and pits on its surface, but with a little bit of metallic luster.

"Everyone, we're coming!" Huggins' excited voice came over the radio!

Looking at the mission target ahead, Bart's heart couldn't help beating violently!

In the deep and dark space, the three Hummingbird starships slowly slowed down and gradually approached the lonely Spirit Star.

"Attention! We are preparing to land!"

As the captain, Bart took a deep breath to calm down, and said in a deep voice.

After the voice fell, he took the lead in pressing a few buttons on the console in front of him.

Under Yi's control, the speed of the three hummingbird starships continued to decrease, and they gradually approached the uneven surface of the Spirit God star.

The entire "landing" process took about ten minutes.

A slight vibration came from the bottom of the foot.

Bart knew that this was a sign of a successful landing.

The next moment, several hooks stretched out from the bottom of the hummingbird starship, hanging the entire starship firmly on the surface of Spirit God Star.

After the two Hummingbird starships of his teammates stopped, Bart said with some expectation: "One, start mining!"

The holographic image on the console changed quietly.

The modeling of Spirit Star and Hummingbird Starship appeared in front of him.

Then the voice of Weak AI One sounded: "The fuselage is fixed."

"The nanorobot delivery device is unfolding..."

Directly below the cockpit, in front of the round "belly" of the hummingbird starship, a hard drill protruded impressively.

The drill bit gradually stretched out towards the metallic surface of Lingshen Star!

At the moment of contact, a strong shock came!

This is, after all, an asteroid made of iron and nickel!

Under countless flying sparks and strong vibrations, the extremely hard drill bit gradually penetrated into the surface.

Through the porthole, Bart looked at the sparks splashing on the bottom of the other two Hummingbird starships, and while he was excited, his eyes revealed a somewhat strange color.

At this moment, he suddenly discovered the reason why this starship was named Hummingbird.

A round belly, plus a long drill rod...

I have to say that from a distance, it does look a bit like a hummingbird foraging.

"Drilling is complete." One's voice sounded again, "Start launching mining-type nanorobots."

As soon as the voice fell, the holographic projection screen in front of him changed again.

Countless silver-white substances rushed into the drilling hole frantically through the drilling rod!

In just a few seconds, lines of Chinese were quickly brushed across the holographic projection.

"Metal iron detected!"

"Metal nickel detected!"

"Metallic gold detected!"

"..."

Inside Spirit Star, countless silver-white nano-robots frantically devoured the identified minerals in front of them.

The size of the drilling hole expands at a speed visible to the naked eye!

After devouring enough minerals, the nanorobots began to return along the drill pipe.

Their next stop is the warehouse of the hummingbird starship.

In the warehouse, they will spit out all the devoured minerals.

Then, they will embark on the journey of devouring minerals again and start the next cycle!

Under the wireless power supply module equipped with the Hummingbird starship, these nano-robots are tirelessly digging out the abundant resources inside the Spirit Star!

Chapter 212 The increasingly full technology tree

Through the images from the camera, Bart clearly saw that in the starship warehouse, with the efforts of countless mining-type nano-robots, a pile of silver-white metallic objects slowly took shape.

On the surface of the silver-white object, there is still a little bit of golden light shining!

These are pure heavy metals from the interior of Spirit God Star.

Bart looked at the scene in front of him with excitement.

Suddenly, Professor Chris's clear voice came from the radio of the starship.

"Call Hummingbird 1, call Hummingbird 1, please answer!"

Bart instantly woke up from the mining scene in front of him.

There was an awkward smile on his face.

It's broken, I was too engrossed in watching it, and forgot to report to work for a while.

He hurriedly pressed the radio switch, and quickly responded: "Hummingbird No. [-] received!"

"Professor Chris, the mining nanorobots are working fine."

……

No. [-] Mars City, command center.

Professor Chris stood anxiously on the podium, reaching out to wipe the sweat from his forehead.

Even though the temperature in the command center was at the most comfortable temperature under zero control, he still felt a little hot and dry.

There is no other reason.

A big man was sitting at the side, staring at him.

Professor Lu Yongchang, Chairman of the Council...

It can be said that the trial operation of the hummingbird mining ship has attracted the attention of most high-level officials in Mars City.

This is related to a series of plans for the future of mankind.

What rushed out of the solar system, colonized the Proxima Centauri, if there is not sufficient mineral resources, all this becomes empty talk.

After all, without resources, they simply cannot build super-large starships that can sail across star systems.

As the person in charge of the original NASA Mars Pathfinder program, Professor Chris is actually a scientific researcher who has taken on important responsibilities.

But this time the burden is really a bit heavy.

While looking at the three hummingbird starships motionless after arriving at the destination on the holographic image in front of him, he kept reaching out to wipe the sweat from his forehead.

"Hiss..." Professor Chris glanced at Lu Yongchang, and said to himself nervously, "Why hasn't there been news yet..."

"Calculating the time, it should be enough..."

Lu Yongchang didn't speak, just sat quietly on the seat, closed his eyes, and looked at him peacefully.

But this attitude undoubtedly aggravated the pressure in Professor Chris's heart.

He reached out to wipe his sweat more and more frequently.

While glancing at Lu Yongchang from the corner of his eye, he sighed wryly in his heart.

Before the People's Federation was established, he regarded Lu Yongchang as his old enemy.

Lu Yongchang single-handedly provoked the dispute between the United States and the Xia State in the field of spaceflight.

but now……

Looking at Lu Yongchang who was sitting on the seat far away, exuding a strong oppressive aura even with his eyes closed, Professor Chris felt even more bitter.

He couldn't help complaining to the three starship pilots in a low voice.

I don't know what the hell I'm doing...

It has been more than 20 minutes since I arrived at Spirit God Star, and I was so stunned that I couldn't even fart.

As for taking the initiative to ask about mining progress...Professor Chris glanced at Lu Yongchang who was on the side, and dismissed the idea.

He didn't want to be labeled as impatient.

After all, this hummingbird-type mining ship experiment was also a ladder for him, Chris, to climb up.

……

As for Lu Yongchang, at this moment, he didn't care about the experimental progress of Professor Chris and the hummingbird mining ship.

While everyone was waiting, his consciousness had already come to the technology tree space again.

Against the background of fluorescent green, a tree-shaped diagram shining with crystal white light came into his eyes.

As time went by, the technology tree of this first-level civilization became more and more full.

The technology tree, which originally only had a trunk, has also extended countless small "branches" at this time.

Those are subsidiary technologies of the first-level civilization.

In the case that the main technology has been achieved, it is only a matter of time before these minor technologies are completed.

only……

Lu Yongchang frowned and looked towards the upper left of the technology tree.

There's a relatively large vacancy over there.

It just corresponds to the energy weapon technology of the second-level civilization.

Lu Yongchang focused his attention on that vacancy.

After a short wait, a bit of enlightenment flashed in his mind.

……

He slowly opened his eyes, deep in his eyes revealing a bit of thought.

"Yongchang, the Hummingbird starship will be safe, right?"

A slight questioning sound from the chairman of the council came from the side.

Lu Yongchang froze for a moment, then looked in the direction of Professor Chris.

I saw him sweating profusely looking at the holographic image in front of him, like an ant on a hot pot.

"Professor Chris." Lu Yongchang glanced at the time, frowned slightly, and shouted.

"Yes... yes!" Hearing Lu Yongchang's voice suddenly, Professor Chris's expression changed slightly, and he responded with a bit of panic in his tone.

"Professor, don't worry." A gentle smile appeared on Lu Yongchang's face, and he said softly, "Ask them, I guess I forgot about it because of the busy mining."

"Okay, okay."

Facing Lu Yongchang's gentle expression, Professor Chris's anxiety gradually eased a bit.

He cleared his throat, and sent an inquiry to Bart and others far away in the asteroid belt.

At the same time, the chairman turned his head, frowned slightly and said, "Yongchang, this Chris, why does he seem a bit unreliable?"

"I remember that something happened to the Pathfinder project he was in charge of?"

Lu Yongchang was stunned for a moment, and then a deep smile appeared on his face.

"Sir, don't worry."

"We should let them worry about trivial matters of this level, and treat them as training talents." The smile on the corner of Lu Yongchang's mouth became more and more intense, "With the existence of zero, there will be no major problems."

The MP understood and nodded silently.

"By the way, after the mining project is successful, it's time for us to start preparing for the research and development of the interstellar starship?" The head of the congressman seemed to have remembered something, turned his head again and asked, "We don't have much time left, right?" ?”

Lu Yongchang frowned slightly, and the reminder he had just received flickered again in his mind.
