Cataclysmic Era: I can unlock the tech tree

Upon hearing Su Yutong's question, Lü Yongchang hurriedly shook his head.

Are you kidding me?

Should we go see Dr. Wen again?

Even if Lü Yongchang faints again, he will not go to Dr. Wen for a checkup!

"Then just now..." Su Yutong's eyes showed even more worry, "your reaction was just like last time."

Lu Yongchang was slightly taken aback, then realized the meaning behind Su Yutong's words.

It's estimated that the moment his technology tree broke through the limitations of a Level 1 civilization, his brain "load" exceeded the limit again.

He waved his hand casually: "It's alright, no need to waste time checking."

"This time is different from last time; I know what I'm doing."

As he spoke, Lü Yongchang suddenly froze.

The words Dr. Wen had spoken to him more than three months ago flashed through his mind.

For the past three months, he has been mostly in the main laboratory and has been so busy that he forgot about this matter for a while.

It seems... Dr. Wen said that Su Yutong brought him there crying?

Thinking of this, Lü Yongchang frowned slightly, a complex emotion rising in his heart.

He sighed softly and made a decision.

"Yutong, there's something I need to tell you."

Before Su Yutong could react, Lü Yongchang continued, "I've seen all your hard work over this long period of time."

I understand what you're thinking.

"However, human civilization is still in an extremely dangerous situation. If we are not careful, the entire civilization will fall into an abyss and never recover."

"so……"

"I know!" Su Yutong interrupted him directly, her beautiful eyes fixed on Lü Yongchang's eyes. "I will keep waiting."

"When human civilization truly escapes the crisis."

Lu Yongchang's eyes glazed over slightly, and he subconsciously avoided Su Yutong's somewhat intense gaze.

"Thanks……"

He said softly.

Then, he lowered his head again and threw himself into the pile of documents in front of him.

As the familiar scratching sound of a fountain pen rang out, the atmosphere in the office gradually returned to normal.

……

After the breakthrough in single-photon control technology, the experiment entered another level.

They now need to simultaneously manipulate two photons in a quantum entangled state to verify the possibility of long-distance communication.

then……

While waiting for the second single-photon control device to be manufactured, all the researchers involved were filled with anxiety.

A few days later, as usual, Lü Yongchang walked into the main laboratory for a routine inspection.

Looking at the other single-photon control device, which was already more than half-built, a burning desire shone in his eyes.

Once it is confirmed that two photons in a quantum entangled state can be manipulated and observed, the foundation for two-way long-distance communication will be completely laid!

"Professor Lü!"

A slightly weary shout came from the side.

"Professor Tang?" Seeing the elderly man slowly walking towards him, Lü Yongchang hurriedly went to greet him. "What brings you to the lab?"

"I remember today isn't a day off?"

Faced with Lü Yongchang's question, Old Tang immediately showed a wry smile.

"rest?"

"Professor, no offense, but do you think any researcher would be in the mood to rest if this thing were sitting in the lab?"

As he spoke, Professor Tang pointed to the single-photon control device, which was more than half-finished, in the center of the main laboratory: "Now, all the researchers are waiting for the second experiment!"

Lu Yongchang looked at the gray-haired old man in front of him, both amused and exasperated: "Mr. Tang, I'm even more anxious than you are!"

"Huh?" Just as the two stood there staring at each other, the laboratory door opened again, and a somewhat familiar voice came from inside, "Professor Lü? Professor Tang? You're both here?"

Lü Yongchang silently looked towards the direction of the laboratory door.

Well, here comes another one.

Seeing Mo Zeyang approaching with a smile on his face, Lü Yongchang sighed silently.

These people are even giving up their holidays!

……

More than ten minutes later.

Because the experimental setup has not yet been completed, all work has come to a standstill.

So... the three of them could only sit quietly in their chairs, staring at each other.

"Professor, are there really no other research projects?" Mo Zeyang twisted his body and asked awkwardly.

"So, the architecture of the new quantum computer that you were originally in charge of is complete?" Lü Yongchang asked softly.

"……not yet."

Faced with Lü Yongchang's questioning, Mo Zeyang honestly replied, "Currently, superconducting circuit quantum computers have encountered a bottleneck, and it is unlikely that the number of qubits can be increased simply in the short term."

"We are looking for new solutions, but given the current situation... it's a bit difficult."

Upon hearing this answer, Lü Yongchang's eyes flickered slightly.

The scene he had seen a few days ago flashed through his mind.

or……

"Well, speaking of which, there is indeed a new research project." A faint smile appeared on Lü Yongchang's lips. "However, this project might be a bit difficult. You can take your time to think about it."

"What project?!" Mo Zeyang's eyes lit up, and his expression immediately became excited.

"Photonic computer"

Lu Yongchang gestured towards the single-photon control device next to him: "That is, the original optical quantum computer. I think this should be the next direction for the development of quantum computers."

Mo Zeyang nodded thoughtfully: "That makes sense... I'll go back and think about it carefully!"

With that, he stood up and walked straight toward the laboratory door.

"Professor Lü?"

Looking at Tang Wenshan beside him, Lü Yongchang couldn't help but feel a headache coming on: "Old Tang, you're getting on in years, why don't you rest a bit more?"

Seeing Old Tang's slightly stubborn expression, Lü Yongchang's eyes twitched slightly.

"Okay, there's one more small project."

"If the next experiment is successful, we need to develop a new algorithm to adapt to quantum long-distance communication."

Upon hearing this, a smile immediately appeared on Old Tang's face.

"You've come to the right person."

"I was the one who developed the original quantum communication algorithm."

"Wait a minute, I'll go back and think about it!"

With that, Tang Wenshan excitedly walked out of the laboratory.

Suddenly, only Lü Yongchang remained in the main laboratory.

He shrugged, preparing to check the paperwork before heading back to his office to finish the remaining chores.

Suddenly, the holographic image automatically activated beside him.

Zero's virtual avatar had a very serious expression: "Professor, there is something you need to look at."

Before Lü Yongchang could react, the holographic image subtly changed.

A signal band appeared in front of him.

"This is……"

Lu Yongchang's brows furrowed instantly.

"Professor, this is a signal received by the original Xia Kingdom's Sky Eye system."

"The signal originates from Proxima Centauri."
