Age of Cataclysm: I can light up the technology tree

There was another moment of silence.

Without waiting for the desired response, Su Yutong's eyes showed a hint of disappointment, and the smile on his face gradually faded.

Just when she was about to find a topic to talk about, Lu Yongchang's voice suddenly sounded.

"I hope that when I am 200 years old, I can also receive your cake."

"Still, there are still 300 years, 400 years..."

Lu Yongchang's voice became weaker and weaker, and in the end, it was like a mosquito.

But to Su Yutong's ears, this was the most beautiful sound in decades!

A touch of surprise instantly burst out in her eyes!

"good!"

Her cheeks were slightly red, her eyes were twitching, and she responded in a low voice.

Facing Su Yutong's extremely fiery gaze, Lu Yongchang subconsciously shifted his gaze.

Even though his brain was continuously strengthened by the system, at this moment, he felt dizzy as if he was drunk.

‘Now, the hormone levels in my body should be high, right? ’

An idea suddenly came to Lu Yongchang's mind.

Afterwards, this thought kept drifting away.

‘Are the effects of hormones really that great on the human body? ’

‘Does the human body’s consciousness affect hormones, or does hormones affect consciousness? ’

'If I were only conscious, could I still feel this way? ’

‘…’

"Professor? Professor?"

Looking at Lu Yongchang who was standing there in a daze, a trace of doubt flashed in Su Yutong's eyes, and he stretched out his hand and waved it in front of him: "What are you thinking about?"

Lu Yongchang suddenly came back to his senses.

Looking at Su Yutong, whose cheeks were still slightly rosy, he panicked.

what to do?

Is it possible to tell her that she is thinking about the relationship between hormones and consciousness? !

Will die!

No matter which way it is, you will die!

"cough!"

Lu Yongchang coughed hard, and his system-enhanced brain began to work crazily.

"Yes, that's right."

Lu Yongchang reached out and grabbed the small cake in front of him and said in a hurry: "I suddenly had an idea!"

"I have to go to the office!"

Su Yutong was stunned.

Although she always felt that something was wrong, thinking of Lu Yongchang's previous behaviors, she still smiled and said: "Okay."

"It's time for me to get busy."

Seeing Su Yutong turn and leave, Lu Yongchang breathed a long sigh of relief.

"Professor, is this love?"

Suddenly, Zero's voice suddenly came from beside him.

"..."

In just a few seconds, Lu Yongchang's face turned red.

"This, how is this love?"

"However, according to my observations, the current behavior patterns of you and Professor Su Yutong are very consistent with..."

"Shut up!" Lu Yongchang lowered his voice and shouted in a strong tone.

Then, while unconsciously walking towards the office, he blushed and muttered in a low voice: "How can this be called love?"

"If you are doing scientific research, can that be called love?"

…

Two years later.

Ross 2 star.

Viewed from a high altitude, the whole body is earthy yellow, with a thin "ribbon" winding across the vast expanse of land.

It was a broad freshwater river named the Ross River.

Detection data shows that the Ross River is 4,103 kilometers long.

The starting point is the snowy mountains near the equator.

The melting snow continued to gather, gradually forming this wide river that stretches for more than 4,000 kilometers!

The average width of the Ross River is 82 kilometers, and the widest point reaches 230 kilometers.

The average depth is 11.4 meters, and the deepest reaches 37 meters!

Although it is the only fresh water source on the surface of Ross 2, its huge water storage capacity can fully meet the needs of human civilization.

After all, compared with before, after becoming an interstellar civilization, human beings' recycling rate of water resources has been greatly improved.

Next to this thousands-kilometer ribbon, a "drop" of silver-white pearls suddenly appeared.

That was the first city built by mankind - Central City!

In just two years.

A huge hemispherical building rises beside this wide river!

An overall skeleton made of carbyne, plus a skin made of carbon nanotube material...

It is no exaggeration to say that this central city can even withstand the impact of some small meteorites!

Next to Central City, on the other side of the Ross River, construction of a second city also started not long ago.

If you zoom in closer, you can even see a huge army of robots and robotic arms on the foundation!

Under Zero's command, these robots and robotic arms worked tirelessly day and night.

The construction progress of City No. 2 is also advancing at a speed visible to the naked eye!

…

Above Ross 2.

【Earth】port.

Scientific researchers wearing spacesuits lined up neatly and walked towards Xuannv 2 in front of them.

Through the glass mask, you can clearly see the anticipation and excitement in everyone's eyes!

The most perfect place for human beings to live since leaving the earth is right before our eyes!

"I can finally live a stable life!"

Tao Yuda, who was in the queue, had joy written all over his face.

Because he was wearing a helmet, He Bilin beside him did not hear him talking to himself.

From He Bilin's perspective, Tao Yuda was mumbling something with a "moron" look on his face.

Although Tao Yuda belonged to his elders, he still reached out and knocked on the helmet in front of him mercilessly.

"Shh..."

A burst of electric current sounded in the helmet.

The two connected to the private communication channel.

"What's wrong?" Tao Yuda looked confused.

So... He Bilin described the scene he had just seen with an extremely disgusted expression.

"Isn't it just landing on a planet?"

"Academician Tao, is it necessary to be so excited?"

Tao Yuda laughed awkwardly, and then looked at He Bilin in front of him with complicated eyes.

"Ah..."

He sighed softly.

"After so many years, I can finally step on the yellow soil and see the blue sky and white clouds again... You won't understand this feeling."

He Bilin curled his lips: "What's the big deal... Can't we see it anytime in the holographic theater?"

Tao Yuda's eyes became more complicated.

He shook his head repeatedly: "It's different."

"It's a pity that the environment of Ross 2 is not suitable for human survival, otherwise, I'll take you out for a walk and you'll understand."

"Imagine, on a lush grassland, with a lush forest in the distance, a sunny day, blue sky and white clouds, and the feeling of the breeze blowing on your face..."

"That's the breath of freedom!"

He Bilin was silent for a while and said again.

"The starship fresh air system, high-power daylight, and holographic theater can show it perfectly."

Tao Yuda sighed deeply.

He no longer explained, but just reached out and patted his shoulder: "I hope that one day I can let you feel real freedom."

After speaking, he turned around and followed the pace of the team.

Looking at Tao Yuda's back, the doubts in He Bilin's eyes became more and more intense.
