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

Cao Liangcai on the side looked at Lu Yongchang's suddenly agitated expression, and his expression became strange.

This child...wouldn't be scared stupid?

Lu Yongchang suddenly came back to his senses.

He didn't pay attention to Cao Liangcai's weird eyes, and said excitedly: "I know! I know!!"

Cao Liangcai: "???"

"You, what do you know?"

Cao Liangcai looked at Lu Yongchang in front of him in confusion.

Lu Yongchang took a deep breath and calmed down the turmoil in his heart.

He pondered for a moment, thinking about his wording.

After all, he can't tell Cao Liangcai directly that he doesn't need to worry about the invasion of Proxima civilization in the next 20 years, right?

Without a basis, it is impossible for people to believe in themselves!

"Old Cao, think about it, what is the propulsion power of our Hall thruster?" Lu Yongchang's eyes were shining brightly, "Although I don't know what level of technology the Proxima civilization has reached, since we are using Hall thrusters With the sensor, we can roughly estimate how fast it’s going.”

"It's only one-tenth of the speed of light!"

"What does this speed mean?"

Cao Liangcai's eyes gradually brightened, and he accepted Lu Yongchang's words: "It means that the spacecraft on the moon will take at least 42.2 years to reach Proxima Centauri!"

"Bingo!" Lu Yongchang snapped his fingers lightly.

"Even if they have plans to invade the solar system, when their fleet comes over..."

"Assuming that the Proxima Centauri civilization has made a technological breakthrough at this time, and assuming that their travel speed reaches the speed of light, it will take 4.2 years for them to reach the solar system."

"What's more, it is still unknown whether the Hall thruster can drive the spacecraft to reach one-tenth of the speed of light!" Lu Yongchang said with a smile, "I reckon that it would be good if it can reach one percent of the speed of light."

"So, we don't have to think about the Proxima Centauri civilization at all now."

Cao Liangcai's eyes flashed with excitement.

This feeling is like returning to a simple dungeon after going through a difficult dungeon, comfortable and easy!

Lu Yongchang continued: "As for the civilization of Proxima Centauri... since they are still using Hall thrusters, it means that their civilization is not far behind ours. As long as our technology develops fast enough, we can completely reverse the invasion them!"

Cao Liangcai's eyes suddenly became strange.

So you start thinking about invading other civilizations?

As expected of a young man, he is so angry!

……

After a short period of excitement, Cao Liangcai gradually calmed down.

"So, what should we do now?"

"Continue to develop aerospace technology?"

Lu Yongchang pondered for a moment, then nodded slightly.

"Aerospace technology must continue to advance."

"The Xuannv No. [-] project should also be launched, and this part of the research content is left to you."

Cao Liangcai: "???"

He pointed at himself with a look of surprise: "Leave it to me? What about you?"

"Of course I have more important things." Lu Yongchang looked worried, "The current manufacturing efficiency is too low. According to the current development speed, in 15 years, 1 people can escape from the entire earth." Not bad!"

"By the way, the construction of Xiaguo No. [-] Laboratory has been completed. Lao Cao, you can also prepare to move there. The experimental equipment over there is more advanced."

Cao Liangcai was taken aback when he heard that.

Manufacturing efficiency is too low?

This was the first time Cao Liangcai heard this sentence on the land of Xia Kingdom.

"Wait, wait! How are you going to improve manufacturing efficiency?"

Seeing that Lu Yongchang was about to turn around and leave, Cao Liangcai quickly reached out and grabbed his sleeve: "Let me remind you, the things used in space are manufactured with high precision, and it is normal to make them slower!"

The moment he turned around, Lu Yongchang's eyes flashed bright green.

He said softly: "Artificial intelligence, artificial intelligence in the true sense."

……

Sitting in the car heading to Xiaguo No. [-] Laboratory, Lu Yongchang fell into deep thought.

According to the technology tree given by the system, artificial intelligence is an essential technology to achieve high-efficiency precision manufacturing.

As a scientific research project on the earth, the artificial intelligence project has attracted countless funds and talents, but the results are not very satisfactory.

After spending a lot of time and energy, the current artificial intelligence...except for being able to outperform humans in some specific fields, most of the time, it is still at the level of artificial mental retardation.

As for how to realize artificial intelligence in the true sense, to be honest, Lu Yongchang has no clue now.

He took a deep breath and slowly closed his eyes.

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

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

Lu Yongchang felt a little uneasy.

I don't know if the system will give him a reminder like last time.

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

The white light spot draws a beautiful curve, slowly pointing to the artificial intelligence cursor.

The next moment, a hidden dim cursor appeared on the path of the white light spot.

[Cradle of Artificial Intelligence: Preliminary Control of Quantum Computer Technology]

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

It seems that there are new tasks.

Quantum computer... He didn't know anything about it in his previous life.

Thinking of his upcoming study time, a bitter smile appeared on his face.

……

Xiaguo First Laboratory.

Lu Yongchang, who had just got off the car, walked towards his office in a hurry.

"Lu, Professor Lu!"

A familiar voice came from the side.

Lu Yongchang was stunned for a moment, subconsciously stopped and looked aside.

The moment he saw the person coming, a trance appeared in the depths of his eyes.

Dressed in a white robe, with the high ponytail and rimless glasses, Lu Yongchang once thought he had returned to his previous life.

"Su Yutong?"

"Why are you here?"

The corners of Su Yutong's mouth twitched slightly, revealing a faint smile, and said in that unique cold voice: "Professor Lu, have you forgotten?"

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

Chapter 93 If you can accept it, come with me

Facing the familiar yet unfamiliar voice, Lu Yongchang took a deep breath.

Ok.

He really put the matter behind him.

"So, what are you doing in the lab now?"

A trace of embarrassment flashed in Su Yutong's eyes: "Academician Fang Xu asked me to be your assistant, but you have not been in the laboratory, so I..."

Lu Yongchang: "..."

What a "good" deputy to him!

He silently made a note in his heart.

I have to find a chance to let Fang Xu do some hard work.

"Professor Lu?"

Su Yutong's voice interrupted Lu Yongchang's meditation.

Lu Yongchang was silent for a while.

This is really a "hot potato".

According to his original temperament, when the sun crisis has not been resolved, he must keep his distance from such things.

But now...Professor Guan Hualiang can be regarded as his mentor in the previous life, and Lu Yongchang was a little embarrassed to disobey his "order".

On the other hand, Lu Yongchang didn't know what to ask Su Yutong to do.

Now she is far from reaching the level of her previous life.

After thinking about it, Lu Yongchang sighed slightly.

"Forget it... Since Fang Xu said so, you can study with me."

Later, Lu Yongchang gave her a general introduction to the situation faced by human beings.

Before Su Yutong recovered from the shock, Lu Yongchang continued mercilessly: "I told you in advance that the current human situation is very difficult."

"Our tasks are very heavy, and we basically don't have time to take care of you."

"Besides, I hope you don't disturb other scientific researchers. Also, laboratory work will be very tiring."

"If you can accept it, you can come with me."

After speaking, Lu Yongchang turned and walked towards the office.

Looking at the back of Lu Yongchang going away, the expression in Su Yutong's eyes gradually became complicated.

After a brief pause, she stepped up to catch up with Lu Yongchang.

……

"Professor Lu!"

"Hello Professor Lu!"

As Lu Yongchang walked into the laboratory, there was a steady stream of greetings from the side.

Su Yutong who was following behind had a flash of surprise in his eyes.

Unexpectedly, his status in the laboratory is so high!

"Yongchang?! Damn you are back!"

Fang Xu jumped out from the side suddenly: "Do you know that in order to complete that small fusion reactor, I didn't even have a full night's sleep!"

"Okay, okay, I'll talk about this nonsense later, the situation is urgent now."

Lu Yongchang's hasty words made Fang Xu stunned: "What's wrong?"

"There is a civilization on Proxima Centauri, and the coordinates of human beings have been exposed." Lu Yongchang said succinctly, "Our research progress is still too slow!"

This short sentence contained too much information, which directly made Fang Xu stunned.

"Hello?" Lu Yongchang frowned, "Can people still enter my office?"

"Ah?" Fang Xu blinked his eyes, looking confused.

"After such a long time, my office won't be full of dust, right?" Lu Yongchang walked straight towards the office without stopping, "You didn't clean it for me, did you?"

"Professor Lu, I have already cleaned the office."

Su Yutong's voice sounded behind him.
