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

Lu Yongchang, who was following the old man, had a wry smile on his lips, and he didn't know what the chairman was going to show him.

He let go of the doubts in his heart and silently followed behind the old man, involuntarily thinking about the problems that had troubled him for a long time in his mind.

……

"arrive."

The old man's voice came over the radio again.

Lu Yongchang, who was silently thinking with his head down, suddenly raised his head.

His eyes widened suddenly.

sparkling.

A small lake unfolded in front of him.

On the surface of the lake, there are dots of starlight and the lights of Mars City.

Looking at the scene in front of him, Lu Yongchang's eyes flashed a bit in a daze.

If it wasn't for the red soil around him reminding him all the time, he even thought he had traveled back to the previous earth again.

"This lake slowly appeared more than a month ago." The old man's voice sounded again.

"In the beginning, it was just that the soil was a little wet, and we didn't pay much attention."

"But who knew, over time, it slowly accumulated a small lake."

"...Is the underground ice starting to melt?" Lu Yongchang was silent for a while, then asked softly.

The old man nodded silently.

"After the sun began to become a red giant star, the surface temperature of Mars continued to rise."

"The subterranean ice in this crater also began to gradually melt, and finally formed this lake."

"That's what those researchers told me." The old man shrugged and added, "I don't know about this either. All I know is that this is a good scenic spot."

There was a faint smile on the corner of Lu Yongchang's mouth.

Immediately, he remembered a question.

"Have they tested for biological status?"

"It's not going to do any harm, is it?"

The old man waved his hand and said with a smile, "Don't worry, everything has been tested."

"Since the Gale bacteria incident, the disinfection measures in Mars City have been strengthened a lot. With medical nano-robots, these microorganisms will not be brought back under normal circumstances."

"Not to mention, the area is being monitored all the time."

Hearing this, Lu Yongchang breathed a sigh of relief, and looked up at the lake again.

Suddenly, his eyes moved slightly.

He seemed to see something by the lake.

"Chairman?" Lu Yongchang frowned slightly, pointed to a shadow in the distance, "Did you see that?"

The old man's laughter came over the team radio.

Lu Yongchang frowned even deeper.

Did he read wrong?

Just as he was struggling, the old man's voice sounded again: "You finally found out!"

Lu Yongchang's eyes became more suspicious.

The old man didn't say the answer, but walked towards the small lake silently.

Lv Yongchang, who was afraid of accidents, hastened to keep up with the pace of the old man.

As the distance got closer, Lu Yongchang also gradually discovered the true face of the circular shadow.

a plant.

No, to be precise, it should be a fungus.

Just like the mushrooms on Earth, except that they are bigger.

The purple-red mushroom cap with a diameter of more than one meter lay quietly on the ground.

"Is this the fungus we discovered before?" Lu Yongchang walked quickly to the fungus, turned his head and asked the old man, "Has it recovered?"

The old man smiled and nodded lightly: "Yes, it is the fungus that provides hibernin."

"Life will always look for that ray of hope when facing desperation."

Lu Yongchang's eyes were full of amazement.

The miracle of life was completely displayed in front of him at this moment.

Even after countless billions of years of changes, the life under Mars still survives in an extremely tenacious way.

"In the past month, traces of these fungi have been found in many places near the equator of Mars." The old man walked up to Lu Yongchang, reached out and touched the purple-red mushroom cap lightly, "according to zero's calculation , In the next year, the subsurface ice of Mars and the ice caps at the poles will gradually melt."

"In the next few years, Mars may even become a second Earth."

"It's a pity." Lu Yongchang stood up, let out a long breath and said, "The good times don't last long."

"When the helium flash erupts, these lives that have finally waited for the second spring will still be in a desperate situation."

"Yeah, it's really a pity." The old man nodded with emotion.

Afterwards, the old man put his hand on Lu Yongchang's shoulder, and patted it lightly twice: "Don't put too much pressure on yourself, you have done enough."

Lu Yongchang nodded silently, staring deeply at the purple-red fungus in front of him.

At this moment, his thoughts that had been silent for a long time gradually became active.

At the same time, the expression on his face gradually became alive.

"What? Got an idea?"

There was a bit of a smile in the old man's voice.

Lu Yongchang nodded vigorously, and cast a grateful look at the old man.

"Okay!" The old man laughed loudly, turned around and walked towards the road he came from.

"Now that we have an idea, we should go back."

"Yongchang, remember, don't push yourself too hard."

"What you have done is good enough. Even if human beings can only go so far, I believe that no one will hate you."

Chapter 211 Spirit God Star

two months later.

The night trip to Mars on New Year's Eve obviously relieved Lu Yongchang's tense nerves.

Thanks to this, the subsequent research and development process became much smoother.

In just one month, under the leadership of Lu Yongchang, the research and development project of mining-type nanorobots has made a huge breakthrough!

……

Port 1 Mars.

Three strangely shaped starships parked quietly at the port.

The cockpit of the starship is very small, about one-third the size of the cockpit of Xuannv No. [-]. Therefore, each starship has only one pilot.

But it has an extremely round "belly".

In the "belly", except for the warehouse loaded with ore, it is full of trillions of mining-type nanorobots.

On the shell of the starship, there are two large, shiny characters printed on it.

Hummingbird.

This is the name of this starship.

The total length of the hummingbird starship is only 100 meters. Compared with Luanniao I, its size is ridiculously small.

But it is equipped with the same Hall thruster and fusion reactor as the Luanniao I starship.

This design is also to meet the needs of its work: mining and transporting minerals.

……

Inside the No. [-] Hummingbird starship, a blond man in a spacesuit sat quietly in the slightly narrow driver's seat.

"Bart, please answer if you receive it."

The sound of teammates shouting came over the radio.

The man quickly pressed the radio button and responded with a serious expression: "Got it, please tell me."

The voices of the two teammates came one by one.

"Captain, when can we leave?"

"Yes, Captain, I can't wait to go mining in the asteroid belt! Which man can resist the temptation of a space excavator?!"

Listening to the not-so-standard Mandarin on the radio, Bart smiled wryly.

The serious expression on his face suddenly relaxed.

He switched on the radio again and snapped angrily, "Hudgens! What nonsense!"

"What space excavator, this is a hummingbird starship!"

On the radio, there was a sudden burst of laughter.

"Okay!" Bart laughed for a while, and then reminded again, "The scheduled time is coming soon, please be quiet."

After the words fell, Bart restrained his smile a little, and stared ahead through the window.

In the depths of his eyes, there was also full of anticipation.

That's right, what man can resist the allure of space mining?

Although there is no explosives, it is mining on an asteroid after all!

"Call Hummingbird No. 1, please answer!"

There was a clear and familiar voice on the radio.

Bart was taken aback for a moment, and then quickly responded: "Hummingbird 1 received it! Professor Chris, please tell me!"

……

The flight time is extremely boring.

Looking at the unchanging and deep scenery outside the porthole, Bart opened his mouth and yawned big.

He glanced at the screen.

There is still half an hour away from the "target".

Three Hummingbird starships have the same destination!

An asteroid about 200 kilometers in diameter.

Spirit star.

Spirit star

As early as 1852, the asteroid was discovered by Italian astronomers.

Because it contains a large number of minerals, it has always been coveted by humans.

According to observations and calculations, the main components of Lingshen star are iron and nickel.

These are not the most important things.

Most importantly, it contains a lot of heavy metals.

gold, platinum, copper...

As a "walking earth's core", the resources contained in the Spirit God Star are undoubtedly a timely existence for the current human beings!

"Huggins, Jason!" Bart turned on the radio and sent a message to the other two Hummingbird starships, "Cheer up, we're almost there!"
