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

"Zero, calculate the trend of temperature increase during this period."

"receive."

As the electronic synthesizer sounded, a colorful holographic projection appeared above the desk in front of Lu Yongchang.

After the breakthrough of the second-generation holographic projection technology, the original blue holographic projection finally has color.

Looking at the curve with a rising slope, Lu Yongchang sighed slightly.

"It's getting faster and faster."

Zero did not speak, but quietly presented the temperature growth curve in front of Lu Yongchang.

After a moment of silence, Lu Yongchang said again: "Zero, what stage has the sun developed so far?"

The holographic projection screen changes instantly.

A large round fireball with crimson flames all over appeared before his eyes.

This is the "real time" picture from 8 minutes ago.

"Professor, it is completely consistent with your prediction model."

"The sun is aging at an unprecedented rate."

Several curved lines then appeared next to the fireball.

"According to your model predictions, in the next three to six months, the sun's aging rate will increase rapidly, and it will officially enter the red giant stage in two years."

Lu Yongchang's eyes moved slightly: "Two years later... that is August 2034."

"Zero, calculate the change in Earth's temperature for the next year."

A steep curve appeared in front of him.

Looking at the temperature displayed on it, Lu Yongchang's face sank slightly.

really.

The situation in the previous life still happened after all.

The global average temperature rises by 20 degrees, and the temperature in some areas will rise to more than 70 degrees!

Such a temperature means that most parts of the world are no longer suitable for living!

In the previous life, in order to avoid the high temperature, they chose to build dungeons.

this life...

"Ling, ask Fang Xu to come to my office."

……

"Yongchang, are you looking for me?"

Just as Lu Yongchang was staring at the holographic projection on his desk in a daze, the office door opened quietly, and Fang Xu's voice came from the door.

"Yes." Lu Yongchang came back to his senses, stretched out his hand to grab the void, and then made a throwing motion towards Fang Xu, "Look, this is the simulated data for the next three to six months."

The holographic projection that was originally on the desk shrunk in an instant, and "flyed" in front of Fang Xu and unfolded again.

Fang Xu was not surprised by such a sci-fi image.

He said hello to the manipulator beside him: "Zero, make me a cup of tea."

After speaking, he sat on a chair and looked at the data.

"20 degrees Celsius?!" Fang Xu exclaimed, "Are you sure there is no miscalculation of zero?!"

"Academician Fang, please trust my ability." Before Lu Yongchang could speak, Ling's voice sounded from the mechanical arm beside him.

Then, a cup of tea was delivered to Fang Xu.

Fang Xu laughed, reached out to take the teacup, thanked Lu Yongchang quickly and asked, "Yongchang, do you know what the average temperature rises by 20 degrees Celsius?!"

"Of course I know." Lu Yongchang stretched out his hand and squeezed the space between his eyebrows, and said in a low voice, "The sea level will rise by about 60 meters."

"Not to mention other disasters, the living space alone will be compressed a lot."

"It is precisely for this reason that I called you over. We need to determine a plan."

Fang Xu raised his eyebrows: "Are you sure about a plan? Could it be that you still have several plans?"

Lu Yongchang nodded silently.

"The Tower of Babel should be almost finished, right?"

A proud smile suddenly appeared on Fang Xu's face: "Thanks to Academician Mo and the others for successfully launching the third-generation quantum computer, the power of 200 million qubits is too exaggerated."

"It is estimated that in a few days, the Tower of Babel will be officially completed."

"By the way, you probably haven't seen it live, have you? That scene... tsk tsk tsk!"

"There will be opportunities in the future." Lu Yongchang let out a long sigh of relief, "This is the best news I heard today."

"Get ready to start the spaceport project."

"Luanniao series starships should also be put on the agenda."

Hearing this, Fang Xu's eyes gradually became more suspicious: "You mean to start the Heavenly Court plan ahead of time?"

"At present, our technical reserves should not be enough to support interstellar navigation?"

Lu Yongchang shook his head and said, "Of course not."

"The main purpose of the Luanniao starship is still for immigration."

"Immigration?" Fang Xu suddenly realized, "You mean Mars?"

"good."

Lu Yongchang waved his hand in the air: "Zero, give me the star map of the solar system."

The colorful holographic projection instantly magnifies and fills the entire office.

Then, a map of the solar system appeared.

Among them, the fiery red sun occupies most of the space in the holographic projection.

Although they knew that this thing had no effect on reality, the two swallowed slightly when they saw the huge fireball.

"Zero, shrink the sun a little bit, there is no need to present it 1:1."

As Lu Yongchang's words fell, the fireball that occupied most of the two people's sights shrank instantly.

"Look, this is Earth." Lu Yongchang pointed to a blue planet in front of him, "In two years, the sun will officially enter the red giant stage."

"According to calculations, during the 2034 years from August 8 to 2045, the sun will gradually expand and swallow Mercury and Venus."

"Among them, according to the calculation of zero, in 2040, the sun will completely swallow Mercury."

"In 2045, the sun swallows Venus."

"In the same year, the Sun will experience a helium flash."

The holographic image is also changing synchronously, and the fireball projection that symbolizes the sun is getting bigger and bigger, swallowing Mercury and Venus step by step.

And the original azure planet has become a veritable fireball.

A white light flashed, and an extremely ugly lava ball appeared in front of the two of them.

Looking at this simulated scene, Fang Xu took a step back subconsciously.

Chapter 162

"Actually, there is no need to go so far."

Lu Yongchang shrugged, and waved his hand at the huge sun projection beside him, shrinking it back to its original state.

"As long as it reaches 2034, the surface of the earth will not be suitable for human survival."

"As for the solution, I can think of two kinds at the moment."

"The first way is to quickly create a space port with the help of space elevators and zeros."

"Build a giant starship on the spaceport that can hold a million or tens of millions of people."

Fang Xu directly interrupted Lu Yongchang's words: "This, this is impossible!"

"A starship that allows millions or tens of millions of people to live is definitely not the technology we currently have!"

"Listen to me first." Lu Yongchang said helplessly, "When did I say that these people are going to live in it?"

"You!" Fang Xu suffocated suddenly.

In just a few seconds, he reacted: "You mean... the hibernation cabin?!"

Lu Yongchang smiled and nodded.

"I'll do a simple calculation for you."

"The current standard hibernation cabin is 2.5m in length, 1m in width, and 1m in height. Let's treat it as a cuboid."

"Thus, a standard hibernation pod occupies about 2.5 cubic meters of volume."

"We assume 1000 million people are transported."

"If calculated in the simplest way, we only need a cube with a side length of 293 meters to accommodate them all."

"Considering various redundant equipment, maintenance robots, and some necessary power equipment... After zero calculations, a starship with a length of about 800 meters can successfully transport 1000 million people."

"And this starship doesn't need any extra performance." Lu Yongchang raised his eyebrows lightly, "When necessary, it can be just an iron shell with an engine and some sustaining materials."

"In the plan, Zero needs to manufacture more than 500 such starships, and take away 50 billion people first."

"Of the remaining 50 billion, filter out those who are not suitable for interstellar travel, those who died naturally, those who are too old, and those who are unstable, etc., etc., and there are probably 5 million left."

Faced with Lu Yongchang's description, Fang Xu swallowed again.

"Then where are you going to let these tin shells go?"

Lu Yongchang silently stretched out his hand to point to a direction in the solar system.

"The Kuiper Belt."

"In other words, these 50 billion people are equivalent to starting a few years earlier than us."

"With the help of weak artificial intelligence and hibernation capsules, these 50 billion people can at least spend 50 years in the vicinity of the Kuiper belt safely."

"As for what to do in 50 years..."

Lu Yongchang's eyes suddenly dimmed a bit: "If we can't catch up with them in the next 50 years, then the human race will basically be finished."

"As for the remaining [-] million people, as necessary labor and scientific research personnel, I will arrange them in the space port."

"Wait until the technology is mature and the spaceship for interstellar travel is completed, and then start to escape the solar system."

"What about the second solution?" Fang Xu suddenly asked, "Talk about the second solution first."

"Immigration to Mars."

Lu Yongchang said succinctly: "After the sun expands, we can use Mars as a springboard to gain more time for development."

"After obtaining enough resources in the solar system, we will conduct interstellar travel."

"After all, the power of a helium flash cannot reach the entire solar system."

"It's just... I'm not sure how much computing power Zero needs to complete this large-scale immigration plan, and the problem of material consumption is also a big problem."

The office fell into silence again, leaving only a few holographically projected planets slowly orbiting in the sky.

Fang Xu was silent for a moment, then slowly said: "Why don't we combine?"

……

The next day.

A very remote mountain village.

"Hey, the weather is getting hotter and hotter."

A grizzled old man, wearing a white undershirt as in previous years, was sitting in the shade of a tree in front of his house, shaking a bamboo fan to fan the wind.

There is no use for eggs.

In the high temperature of 40 degrees Celsius, even the wind is scalding hot.

"Uncle Qi! Are you still enjoying the shade under the tree?!"
