Age of Cataclysm: I can light up the technology tree

Dawn Star, Laboratory No.1.

"Academician Shen, I think the atmospheric problem should be solved first!"

Lu Yongchang heard Fan Yi's voice as soon as he entered the laboratory.

Sounds like...argument?

Lu Yongchang subconsciously slowed down and looked towards the direction of the sound with interest.

Sure enough, the next moment, Shen Shenwen's voice also sounded.

"No, no, no, water resources are the most important issue. Water resources are too scarce on Dawn Star."

"Sufficient water resources are the basic condition for transforming Earth-like planets!"

"The water resource problem is too difficult to solve!" Faced with Shen Shenwen's words, Fan Yi quickly retorted, "The atmosphere of Dawn Star is not difficult to modify. As long as the oxygen content reaches the standard, humans can take off their masks and live easily in the outside world! "

"hehe."

Shen Shenwen sneered with a mocking look on his face: "Have you forgotten how high the pressure in the outside world is?"

"You..." Fan Yi's face turned red, "Then have you forgotten the human enhancement project in the biological laboratory?!"

"Hey! You little baby!" Shen Siwen said angrily, "When I was studying biosphere technology, you were not born yet!"

"Cough!" Seeing that the "argument" between the two was about to escalate further, Lu Yongchang hurriedly coughed lightly, interrupting the "friendly exchange" between the two.

The voices of argument stopped abruptly.

Shen Shenwen and Fan Yi slowly turned around, and when they saw Lu Yongchang, they both had expressions of hopelessness on their faces.

"Professor, why are you here?" Shen Shenwen asked awkwardly.

Hearing this, Lu Yongchang's expression became strange.

He slowly made a question mark in his mind and gave his own evaluation: 6.

As if he realized that he had said something stupid, Shen Shenwen's expression became more and more embarrassed.

"The discussion was quite good." Lu Yongchang glanced at Shen Shenwen with a half-smile, "How is it? Do you have any ideas for reform?"

"It's... not determined yet." Shen Shenwen said with some confusion, "I think we should increase the water reserves of Dawn Star first, but Fan Yi doesn't agree with my plan."

"Changing the composition of the atmosphere directly, right?" Lu Yongchang took over, smiled and shook his head, "The consumption is too great, we don't have that many resources."

What a joke.

According to the size of the Dawn Star, directly changing its atmospheric composition into an environment similar to that of the Earth would consume resources that he might as well build a surface city cluster!

Hearing this, Shen Shenwen instantly became energetic.

"Professor, do you also think that we should transport water resources from other planets and then slowly transform the Dawn Star environment through plants?"

"I have seen the detector data." Shen Shenwen hurriedly opened a holographic image, "On the eighth planet of the Gliese 555 star system, there is a large amount of water in solid form."

"As long as we keep it..."

…

After introducing his plan, Shen Shenwen looked at Lu Yongchang in front of him expectantly.

Lu Yongchang pondered for a moment, nodded, and then shook his head.

"The general direction is fine."

"Just some details need to be changed."

He reached out and dragged the holographic projection in front of Shen Shenwen.

"Why waste manpower transporting water resources to other planets?"

"It's such a waste."

As he spoke, Lu Yongchang ruthlessly made a big cross on the holographic projection.

"This..." Seeing this, Shen Shenwen couldn't help but froze on the spot, "If we don't do this, where will we get water resources?"

Lu Yongchang waved to the camera: "Zero, open the satellite image."

A photo with a strange angle appeared in front of everyone.

"I didn't do my homework carefully enough." Lu Yongchang joked with Shen Siwen with a smile, and pointed at the upper right corner of the image, "Did you see it?"

Shen Shenwen looked at the picture blankly and murmured to himself: "Comet... comet?"

Under the light of the main star, a comet dragging a long tail flies straight towards the direction of the main star.

"Nero."

Lu Yongchang explained softly: "The name of this comet."

"According to the latest observational data, 90% of its material components are solid ice, as well as some ammonia, methane and interstellar dust."

"Unlike ordinary comets, this comet is very large."

"The radius reaches three hundred kilometers, and the water resources contained in it are enough to make Dawn Star a water-rich planet."

"According to calculations, it will approach Dawn in one year."

Shen Siwen looked at the holographic screen and murmured to himself: "So... Professor, do you want to capture this comet?"

Lu Yongchang smiled and nodded, making a little joke.

"Thank you for the gift of nature."

…

Lu Yongchang opened the already edited information and introduced it in detail.

"From now on, the Academy of Sciences will dispatch one hundred [Taotie] ships to Comet Nero."

"Don't you wait for it to come on its own?" Shen Shenwen asked in surprise.

"I want to, but the situation doesn't allow it." Lu Yongchang shrugged helplessly, "According to observations, it is constantly approaching the main star of Gliese 555. You should know it clearly by looking at the huge comet tail."

"Every moment, it's losing a lot of mass to radiation from its host star."

"This is not okay."

"Those are precious water resources on the future Dawn Star!"

As soon as he finished speaking, there was a burst of laughter in the laboratory.

"After arriving near the comet, Zero will control the robot to cover the surface of the comet with a layer of 'black cloth'." Lv Yongchang didn't care about the laughter of the crowd and continued, "The 'black cloth' made of carbon nanotubes can effectively isolate the radiation of the main star and preserve the mass of the comet as much as possible."

"At the same time, the robot will sample and analyze its components."

"After confirming that it is harmless, one hundred [Taotie] will use carbon nanotube nets to slow it down for up to half a year."

"Finally."

"When it arrives near Dawn, it will be captured by the gravity of Dawn."

Speaking of this, Lv Yongchang made an explosion gesture: "When it enters the atmosphere of Dawn, we will completely smash it to reduce its impact on the ground."

"When a large number of rivers, lakes, and oceans appear on the surface of Dawn, we can start the second step of the plan."

Under Zero's control, the holographic screen quickly switched.

"Ross 154 nitrogen-fixing cyanobacteria."

"Compared with nitrogen-fixing plants on Earth, the nitrogen-fixing cyanobacteria on the planet Ross 154 have a stronger nitrogen-fixing ability and a shorter growth cycle."

"Through genetic modification, we can also give it the ability to photosynthesize."

"While converting part of the carbon dioxide into oxygen, it absorbs a large amount of nitrogen in the atmosphere, thereby greatly reducing the air pressure of Dawn and improving the atmospheric composition of Dawn."
