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

"The production of 250 [Golden Crow] Nebula-class battleships has not yet begun."

"The construction of the new flagship [Earth] has not yet begun."

Lu Yongchang nodded thoughtfully. With the breakthrough in starship manufacturing technology, the original Heavenly Court plan has also been changed accordingly.

The nebula-class starship is the result of the completion of the first-level civilization technology tree.

In other words, these starships contain the pinnacle technology of a first-level civilization.

In Lu Yongchang's plan, starships will be divided into nine classes.

Nebula class, comet class, asteroid class, satellite class, planetary class, star class, white dwarf class, neutron class, and finally black hole class starship.

In Lu Yongchang's view, these starships in the Tianting project can be called nebula-class starships.

And those Luanniao and Xuannv starships in the past can only be regarded as transitional products.

If you insist on counting, perhaps it should be called a satellite-class starship.

"When are all the construction projects expected to be completed?" Lu Yongchang asked directly.

Then Zero's response sounded: "It is estimated that all construction tasks will be completed in October 2042."

August 2042...

Lu Yongchang frowned.

Humans have only two months to avoid the huge solar storm caused by Venus falling into the sun.

As for the escape plan, Lu Yongchang had already thought about it.

After leaving Mars, the human fleet will head straight for Jupiter.

At that time, 1250 starships will "hide" behind Jupiter, and after the solar storm passes, they will set off for the Kuiper belt.

only……

"Will the two months be a little tight?" Lu Yongchang frowned and asked in a low voice.

"Professor, time is enough." Zero quickly presented a series of calculations and deduction results in front of him.

"According to calculations, we will arrive at the back of Jupiter one week before the fall of Venus."

Hearing this, Lu Yongchang's right eyelid twitched slightly: "I hope so."

The office fell into silence again.

"Professor, there is bad news." Zero's voice sounded again.

This familiar tone and voice made Lu Yongchang's right eyelid twitch again.

"hiss……"

He gasped sharply.

How long does it take?

This thing is so smart? !

"Tell me." Lu Yongchang stretched out his hand to hold his forehead, and said weakly, "What's wrong with it?"

Zero's tone was very flat: "Professor, our hydrocarbon reserves have dropped to the warning value."

Lu Yongchang couldn't help being stunned, and then he realized: "Hydrocarbons? How did this thing drop to the warning value?"

The so-called hydrocarbons are nothing more than various hydrocarbon substances.

Methane, acetylene...

In addition to acting as fuel, these substances can also synthesize various chemical substances, which can be described as indispensable raw materials for modern industry.

According to the normal situation, under the perfect industrial system, this thing will not be scarce at all.

For example, carbon dioxide and carbon monoxide can be combined with hydrogen to produce methane.

"The problem of synthesis rate." Zero explained softly, "After the launch of the Heavenly Court Project, our consumption rate is far greater than the synthesis rate."

"Ok."

There was a bit of helplessness in Lu Yongchang's eyes.

These extremely common raw materials on the earth are now even scarce.

"I'll find a way."

After speaking, Lu Yongchang fell into deep thought.

He subconsciously tapped the desk in front of him with his knuckles, and thoughts flashed through his mind one after another.

If it is on the earth, the acquisition of these hydrocarbons can be described as extremely simple.

Extraction from fossil fuels, or biogas digesters...

In conclusion, there are countless ways to obtain large quantities of hydrocarbons.

But after leaving the earth, these methods will not work.

There are no so-called fossil fuels on Mars!

As for the digester...

Now Mars City doesn't have so much organic waste to make biogas!

After thinking for a long time, he decided to turn his attention to other planets.

"Zero, help me open the solar system map and mark the position of Titan."

The holographic image changes silently.

The relative positions of Mars, Jupiter, Saturn, and Titan were instantly presented to Lu Yongchang.

“The relative location is good.”

The moment he saw the holographic screen, Lu Yongchang's eyes lit up: "Ling, call Fang Xu and the others."

"Next, prepare to land on Titan!"

Titan, also known as Titan.

It is the largest of all Saturn's moons and the second largest in the solar system.

Its special feature is that it is the only satellite with a dense atmosphere, and its surface atmospheric pressure even reaches 1.5 times that of the earth!

(Io, Europa, Ganymede, Callisto, Enceladus, and Triton all have atmospheres, but they are extremely thin.)

In addition, Titan's atmospheric composition is very peculiar. In addition to 98.44% nitrogen, there are also a large number of different types of hydrocarbons.

According to the detection, there are oceans and lakes composed of a large number of hydrocarbons on the surface of Titan, whose surface temperature is as low as -179 degrees Celsius!

This is why Lu Yongchang decided to land on Titan.

At that time, the collection ship may even draw large quantities of liquid hydrocarbons directly from Titan's surface methane ocean!

It is convenient and worry-free, and even saves the effort of compressing gas.

In Lu Yongchang's view, there is no better deal than this!

Chapter 239 Titan

"Titan Outpost Project"

Eight large characters floated in front of everyone.

"The specific situation is like this." Lu Yongchang stood in front of the conference table and shrugged.

"Because of the consumption of hydrocarbons, we need to go to Titan to collect various hydrocarbons."

"Everyone, do you have any comments?"

As he spoke, he scanned the crowd around the conference table.

After a few seconds.

"Very well, it seems that everyone has no opinion, so this matter is settled."

"Zero, which pilot is free in Mars City now?"

A holographic image opened in front of Lu Yongchang.

"Zhao Zijie...he's the one."

"Inform him, pack your luggage now." Lu Yongchang immediately said, "Zero, send a Luanniao I starship."

……

after one day.

Zhao Zijie and Gao Yang dragged two large suitcases, and boarded the [Xunmu] space elevator in a daze.

"Zijie, are we going to Saturn?" Until now, Gao Yang still hadn't realized it.

"Titan, to be precise."

Zhao Zijie had a helpless and tired smile on his face.

The two of them had just returned from the asteroid three days earlier and were about to enjoy a week-long vacation.

In the end, a hologram broke all plans.

"God... the Titan outpost plan, the current plan is getting more and more crazy." Gao Yang muttered to himself.

While dragging the suitcase to his side, Zhao Zijie said, "Probably another project proposed by Professor Lu."

"By the way, have you packed your luggage?"

"I reckon we won't be back for at least a few weeks."

Gao Yang patted the suitcase beside him vigorously.

"rest assured!"

The next second, he moved closer to Zhao Zijie's ear and whispered, "Snacks are enough!"

Zhao Zijie's eyes lit up, and he nodded with satisfaction.

……

The time of interstellar travel is extremely boring.

"drop!"

Just as Zhao Zijie and Gao Yang were using guessing games to determine the ownership of the last pack of spicy strips, a clear reminder sounded in the cockpit of Luanniao.

Zhao Zijie quickly turned his head to look at the holographic image in front of the console.

【Arriving at the destination soon, Luanniao I will start to slow down, please enter the deep-sea cabin immediately】

He subconsciously glanced at the surrounding portholes.

A yellow planet with a large ring around it came into view.

That's Saturn.

……

"Cough, cough, cough!"

With the opening of the deep-sea hatch, Zhao Zijie looked up at the porthole while coughing.

A small orange planet came into view.

The picture shows a pseudo-color image of Titan (actually orange) synthesized based on the detection data sent back by "Cassini"

"Ahem! Is this Titan?" Gao Yang's voice came from the side.

Like Zhao Zijie, he was also struggling to cough up some deep sea fluid remaining in his trachea.

Although these deep-sea fluids can be absorbed by the human body, the feeling of them sticking to the trachea is hard to describe.

Therefore, every starship pilot has developed the habit of "coughing when leaving the cabin".

Zhao Zijie stared at the small satellite through the porthole, and nodded slightly.

"If the navigation is correct, it should be."

"What are these yellow things?" Gao Yang took a closer look, frowned and said, "Why do they look like smog?"

"Didn't it mean that most of Titan's atmosphere is nitrogen and hydrocarbons?"
