Age of Cataclysm: I can light up the technology tree

the next day.

Lu Yongchang frowned and looked at the information on the desk in front of him.

The sound of the office door opening came.

He raised his head and glanced at the visitor, then lowered his head again and started looking through the documents.

"Brother Xu?" Lu Yongchang asked softly, "What's the matter?"

Fang Xu naturally didn't care about Lu Yongchang's attitude. He walked to the desk with a smile on his face.

"There are two good news, which one do you want to hear?"

There was a look of doubt in Lu Yongchang's eyes.

He looked away from the documents in front of him and raised his head to look at Fang Xu: "Two?"

Fang Xu nodded: "The first one is related to your speech yesterday."

“Global speaking has made a big difference.”

"Currently, feedback has come from all over the world. It is said that people are much more motivated to flee."

"There are even some people who will take the initiative to help the staff and assist in the implementation of the escape plan."

Lu Yongchang nodded with satisfaction.

"This is indeed good news."

Increasing the enthusiasm for escape can greatly increase the survival rate of escapees.

In interstellar navigation, within the load range, the larger the effective population, the better.

As for what is the effective population...

It's simple and cruel.

They are people who are already productive and will be productive in the future.

In other words, young adults and children.

After all, you never know what surprises may happen in the universe.

Forget about the universe.

Just on Earth, a chain disaster caused by rising global average temperatures killed more than 1 billion people in just a few months.

Although most of these 1 billion people are elderly people with limited mobility, the few young adults and children who died in natural disasters also indirectly weakened the "development potential" of human civilization.

Thinking of this, Lu Yongchang's eyes dimmed a bit.

He sighed softly, shook his head and said, "What a pity..."

"When the hibernation plan is implemented, we don't know how many people will survive."

Fang Xu's face also became a lot heavier.

"Professor, based on the data accumulated in the early stage, it is estimated that the hibernation plan will take about three months to be fully implemented. Considering that extreme weather will become more and more frequent, it is estimated that the number of escapees will decline to about 3.8 billion."

Zero answered sternly, and even listed a large amount of data to prove his inference.

3.8 billion…

A total of 200 million less.

Lu Yongchang's eyes became more sad.

But there was nothing he could do about this situation.

Currently, the spaceport, Luanniao Project and [Jianmu] manufacturing projects have completely drained Zero’s computing power.

If computing power is allocated to build shelters and slows down the progress of other projects, the consequences will only be more serious!

"What's the other good news?"

After a moment of silence, Lu Yongchang took a deep breath, cheered up a little, and asked Fang Xu.

After hearing the question, Fang Xu shook his head and pulled himself out of the heavy atmosphere just now.

"I'm sure you can't guess what the good news is!" Recalling the report he just received, Fang Xu's eyes showed a bit of joy.

Seeing the confusion in Lu Yongchang's eyes, he cleared his throat and prepared to report.

The holographic projection screen quietly changed: "Professor, the Biosphere 2 experiment has achieved initial success."

Fang Xu's expression suddenly froze: "..."

"Zero, don't bring this..."

As for Lu Yongchang, he naturally ignored Fang Xu's "protest" and stood up with excitement on his face, looking at the holographic image in front of him.

"Zero, arrange a Xuannv No. 2 for me. I want to go to the Ecological Sphere No. 2!"

…

Taklimakan Desert.

As the sun changes faster, the desert has become a real forbidden zone for life.

Under the scorching sun, the surface temperature of the Taklimakan Desert reaches over 90 degrees Celsius.

In the center of the Taklimakan Desert, a huge hemispherical glass building stands in this restricted area of ​​life, as if challenging the power of nature.

Xuannv No. 2, which was completely black, drew a graceful curve and slowly landed on the tarmac next to the glass building.

The powerful thrust of the Hall thruster kicked up countless yellow sand.

You can see through the portholes that the world around Xuannv 2 has become a hazy world.

"Professor, we are here."

Zero's voice came: "I have informed Professor Shen Shenwen and he is already waiting for you at the door of the isolation cabin."

Lu Yongchang nodded, then looked at the thermometer aside.

The moment he saw the numbers, he stood up decisively and took out the spacesuit from the cabinet on the side.

Are you kidding me? With the temperature outside right now, he would probably be able to smell the smell of barbecue within a few minutes of going out.

The hatch slowly opened, and Lu Yongchang, wearing a silver-white spacesuit, slowly walked out of Xuannv 2.

Through the mask, he could clearly see several camels turned into mummies on the sand.

He sighed silently and stepped towards the "hatch" of Biosphere 2 in the distance.

To ensure a tight seal, the Biosphere 2 project's hatch structure mimics the design of a spacecraft - a circular hatch that can be drilled through by a single person.

He reached out and grabbed the handle of the circular hatch and twisted it open with force.

After several turns, the "hatch" slowly opened.

He knelt down and got inside.

…

"Professor Lu, hello, hello!"

As soon as he took off his space suit and walked out of the isolation cabin, Lv Yongchang heard an excited shout.

He raised his head and looked in the direction of the sound.

It looked familiar.

"Professor Shen?" He called tentatively.

"Yes, yes, I am Shen Siwen." The man walked up to Lv Yongchang cheerfully and shook his right hand with both hands, "Welcome to Biosphere 2!"

"I also watched the global speech yesterday. You spoke very well!"

Lv Yongchang didn't say too much. He nodded and got straight to the point: "Okay, time is urgent, I won't say any nonsense."

"Tell me about the current situation of Biosphere 2."

"This is related to the future plan of the Human Union!"

When Shen Siwen heard this, his expression suddenly became serious!

"Professor Lu, please follow me."

Said Shen Siwen, turning around and walking inside: "The biosphere is different from other research projects. Some things cannot be concluded by just looking at the data. It is better for me to take you to see it with your own eyes."

Lv Yongchang nodded, which was also his idea.

Otherwise, he could just sit in the office and ask Ling directly about the progress of the project.

Just after walking a short distance, he keenly noticed the abnormality.

He raised his head and looked at the glass dome of Biosphere No. 2, only to see countless silver-white sequins attached to it.

"Professor Shen, this is..."

Shen Siwen turned his head and saw Lu Yongchang looking up, and quickly explained.

"This was just modified recently."

"After the sun changed, the internal refrigeration system could not keep up, so we asked Ling to make these reflective sequins to reflect most of the sunlight and leave only suitable light."
