Cataclysmic Era: I can unlock the tech tree

Lu Yongchang suddenly slapped his...thigh.

He's getting stuck on something!

Why be so fixated on how to escape?!

Humanity is perfectly capable of resisting aggression!

At least, in the previous life, no extraterrestrial civilization from Proxima Centauri appeared in the solar system within the next twenty years!

In that case... as long as their technology develops fast enough, humanity can travel to Proxima Centauri immediately!

Next, of course, comes interstellar warfare!

If we win this interstellar war, human civilization can gain a perfect period of growth!

"Professor Lü...?"

Cao Liangcai, who was standing to the side, looked at Lü Yongchang's suddenly excited expression and his expression became strange.

This child... I hope he wasn't scared out of his wits.

Lü Yongchang suddenly came to his senses.

Ignoring Cao Liangcai's strange look, he excitedly exclaimed, "I understand! I understand!!"

Cao Liangcai: "???"

"What do you know?"

Cao Liangcai looked at Lü Yongchang in front of him with a completely bewildered expression.

Lü Yongchang took a deep breath to calm his turbulent emotions.

He paused for a moment, carefully considering his words.

After all, he couldn't just tell Cao Liangcai that there was no need to worry about an invasion from the Proxima Centauri civilization for the next twenty years, could he?

Without evidence, people can't possibly believe themselves!

"Old Cao, think about it, how much propulsion power do our Hall thrusters have?" Lu Yongchang's eyes gleamed. "Although we don't know what level of technology the Proxima Centauri civilization has reached, since we are using Hall thrusters, we can roughly estimate its speed."

"At most, it's only one-tenth the speed of light!"

"What does this speed mean?"

Cao Liangcai's eyes gradually brightened, and he continued Lü Yongchang's words: "This means that it will take at least 42.2 years for this spacecraft on the moon to reach Proxima Centauri!"

"Bingo!" Lu Yongchang snapped his fingers lightly.

"Even if they intend to invade the solar system, by the time their fleet arrives..."

"Assuming that the Proxima Centauri civilization made a technological breakthrough at that time, and assuming they traveled at the speed of light, it would still take them 4.2 years to reach the solar system."

"Moreover, whether the Hall thrusters can actually propel the spaceship to one-tenth the speed of light is still unknown!" Lu Yongchang said with a smile. "I estimate that reaching one-hundredth the speed of light would be quite good."

"Therefore, we don't need to consider the Proxima Centauri civilization at all right now."

Excitement gleamed in Cao Liangcai's eyes.

This feeling is like going through a difficult dungeon and then returning to an easy one – refreshing and relaxing!

Lu Yongchang continued, "As for the Proxima Centauri civilization... since they are still using Hall thrusters, it means that the gap between their civilization and ours isn't that large. As long as our technological development speed is fast enough, we can completely invade them!"

Cao Liangcai's eyes immediately turned strange.

So they're already thinking about invading other civilizations?

As expected of a young person, they have quite a temper!

……

After a brief moment of excitement, Cao Liangcai gradually calmed down.

"So, what should we do now?"

Should we continue developing aerospace technology?

Lu Yongchang pondered for a moment, then nodded slightly.

"Aerospace technology must continue to be advanced."

"Project Xuan Nu II should be launched soon. This part of the research will be entrusted to you."

Cao Liangcai: "???"

He pointed to himself with a surprised look: "You left it to me? What about you?"

"I naturally have more important matters to attend to." Lu Yongchang's eyes held a hint of worry. "The current manufacturing efficiency is too low. At the current rate of development, in fifteen years, it would be considered good if even ten thousand people could escape from the entire planet!"

"By the way, the first laboratory in Xia Country has been completed. Old Cao, you can also prepare to move there. The experimental equipment there is more advanced."

Cao Liangcai was stunned.

Is the manufacturing efficiency too low?

This was the first time Cao Liangcai had heard this phrase on the land of Xia.

"Wait, wait! How do you plan to increase manufacturing efficiency?"

Seeing that Lü Yongchang was about to turn and leave, Cao Liangcai quickly reached out and grabbed his sleeve: "Let me remind you, the things used in space are manufactured with extremely high precision, so it's normal for them to be manufactured slowly!"

As he turned around, a glint of fluorescent green flashed in Lü Yongchang's eyes.

He said softly, "Artificial intelligence, true artificial intelligence."

……

Sitting in the car on the way to the First Laboratory of Xia Country, Lü Yongchang fell into deep thought.

According to the technology tree provided by the system, artificial intelligence is an essential technology for achieving high-efficiency precision manufacturing.

As a groundbreaking scientific research project, artificial intelligence has attracted countless funds and talents, but the results have been less than ideal.

After spending a lot of time and effort, current artificial intelligence... except for surpassing humans in some specific fields, is still at the level of artificial stupidity most of the time.

As for how to achieve true artificial intelligence, to be honest, Lü Yongchang has no clue at all.

He took a deep breath and slowly closed his eyes.

With a thought, he entered that fluorescent green space once again.

This time, he focused all his attention on the dim cursor.

Lu Yongchang felt somewhat uneasy.

I wonder if the system will give him a notification like it did last time.

Gradually, a sliver of white light appeared from the bottom of the technology tree.

The white dot traced a graceful curve, slowly pointing towards the artificial intelligence cursor.

The next moment, a hidden, dim cursor appeared on the path that the white light dot had passed through.

[The Cradle of Artificial Intelligence: Initial Mastery of Quantum Computer Technology]

Looking at the dim cursor in his mind, Lü Yongchang took a deep breath.

It seems there's a new task ahead.

Quantum computers... He knew absolutely nothing about them in his previous life.

Thinking about the intense studying he would be doing next, a bitter smile appeared on his face.

……

The First Laboratory of Xia Kingdom.

As soon as he got out of the car, Lü Yongchang hurried toward his office.

"Professor Lü!"

A familiar voice came from the side.

Lu Yongchang was stunned for a moment, and subconsciously stopped and looked to the side.

Wearing a white robe, a high ponytail, and rimless glasses, Lü Yongchang once thought he had returned to his past life.

"Su Yutong?"

What are you doing here?

Su Yutong's lips twitched slightly, revealing a faint smile, and she said in her uniquely cool voice, "Professor Lü, have you forgotten?"

"Professor Guan asked me to come here to experience the atmosphere of the laboratory."
