Cataclysmic Era: I can unlock the tech tree

Earth

The Xuan Nu II ship sailed straight toward the port on its belly.

Under Zero's control, the port of the Earth slowly opened.

The Xuan Nu II slowly sailed into the port.

The hatch opened, and Lü Yongchang, wearing a spacesuit, strode out.

After stepping off the spaceship, he frowned and shifted his body uncomfortably.

"Tsk..."

"I finally got used to the gravity of Proxima Centauri b, and then suddenly I'm back in a weightless environment, it feels so..."

As he spoke, he shook his head helplessly.

pity.

He hasn't seen any real artificial gravity technology in the tech tree system yet.

"Zero, have Zhao Zijie wait for me at the command center."

……

Earth Command Center.

The sound of the door opening could be heard.

Zhao Zijie suddenly raised his head and looked towards the gate.

Upon seeing that it was Lü Yongchang, he quickly stood up and bowed.

"professor……"

"Have a seat." Lu Yongchang's eyes showed a hint of weariness as he casually waved his hand. "No need to be so formal."

As he spoke, he walked straight to Zhao Zijie's side and found an empty seat to sit down.

"Click".

The electromagnetic adsorption device made a particularly crisp sound.

"Professor, what's wrong with you...?" Zhao Zijie clearly noticed the fatigue in Lü Yongchang's eyes.

"Just got back from Proxima Centauri b." Lu Yongchang stretched out his hand, pinched his brow hard, and said with forced spirit, "Photonic computing technology has made a breakthrough."

Zhao Zijie was stunned for a moment, then his eyes lit up with wild joy: "Really?!"

"Oh……"

Why would I lie to you about something like this?

Lu Yongchang chuckled and shook his head: "The point of my call for you today is not this."

Upon hearing this, Zhao Zijie's smile immediately faded: "Professor, please speak."

Lü Yongchang hesitated for a moment.

He then took a deep breath: "What are your thoughts on this war?"

After saying that, he stared intently into Zhao Zijie's eyes, trying to discern his inner thoughts.

Zhao Zijie's eyes darted away slightly, and he said softly, "I think it's very good."

"We have won a victory, which has bought human civilization more than a hundred years of peaceful development."

Lu Yongchang's expression remained unchanged: "Tell the truth."

"..."

A few minutes later.

Zhao Zijie shook his head with a wry smile.

"Professor, to be honest, I think this war was a complete failure."

Lu Yongchang showed no surprise at Zhao Zijie's words.

After adjusting his posture, he softly gestured, "Tell me your thoughts."

Zhao Zijie pondered for a moment, organizing his thoughts in his mind.

"Professor, after the war, I conducted several post-war reviews on my own."

At this point, Zhao Zijie showed a hint of hesitation.

Seeing Lü Yongchang's encouraging look, he finally spoke the words that were on his mind.

"Both we and the Proxima Centauri performed terribly in this war."

Lu Yongchang nodded with a wry smile, continuing Zhao Zijie's words: "Like two little brats with absolutely no fighting experience, right?"

Zhao Zijie nodded silently.

Lu Yongchang continued, "That's why I asked you to come here."

"Based on Zero's comprehensive assessment, your performance in the recently concluded war should be considered the best."

"Although there were quite a few mistakes, it's already pretty good compared to others."

Upon hearing this, Zhao Zijie's eyes showed both surprise and confusion.

He was somewhat unclear about the meaning behind Lü Yongchang's words.

He opened his mouth, trying to say something.

But Lü Yongchang didn't give him a chance to interrupt.

"I've thought about it for a long time."

"First of all, given the inevitable interstellar wars of the future, reform is imperative."

Zhao Zijie instinctively held his breath.

"What do you think of the dual command system?" Lü Yongchang asked softly.

"I..." Zhao Zijie's eyes showed even more confusion.

He had never considered such a question.

"I think... you did a great job directing."

Hearing this, Lü Yongchang shook his head with a wry smile: "I probably don't know as much about interstellar warfare as you do."

Zhao Zijie shook his head repeatedly.

"Professor, please don't say that."

"This is humanity's first interstellar war. We know absolutely nothing about the enemy, so achieving such results is already quite remarkable."

"Faced with the new weapons of the Proxima Centauri civilization, only you have come up with a solution."

Lü Yongchang shrugged: "You see, as you said, that's exactly my role."

"Tactical command... I don't have the energy to get involved in that."

"Therefore, I am prepared to activate the dual command system."

"Tactical Command, primarily responsible for tactical deployment in interstellar warfare."

"After comprehensive evaluation, I believe you are the best candidate for this position."

"The technology commander, which is me, will continue to do my job."

"Analyze the technology of enemy civilizations, find vulnerabilities, and then carry out precise strikes."

As he spoke, he extended his right hand to Zhao Zijie: "Let's get to know each other again, I am Lü Yongchang, the Chief Technology Officer of the Human Fleet."

Zhao Zijie's breathing was rapid, and his pupils trembled slightly.

The news came too suddenly.

But seeing the gentle smile on Lü Yongchang's face, his initially panicked mind gradually calmed down.

He took a deep breath, extended his right hand, and grasped Lü Yongchang's right hand firmly.

"Zhao Zijie, Commander-in-Chief of Human Fleet Tactics, please give me your guidance."

……

After letting go, Lü Yongchang clapped his hands with a relaxed expression: "Finally, I've gotten rid of this burden."

Zhao Zijie: "???"

"By the way, tell me more about the debriefing you mentioned earlier," Lü Yongchang said with a smile. "What problems did our fleet encounter during this war?"

"I will improve the fleet based on the suggestions you have made."

Zhao Zijie's expression turned serious, and his back straightened instantly.

This is a big deal!

"The first, and also the most important one."

"Intelligence gathering".

Zhao Zijie said with a solemn expression.

"From the beginning to the end of the war, we did not have enough knowledge about the civilization of our neighboring planet."

"This is what cost the lives of so many of our soldiers."

Lü Yongchang's expression darkened slightly.

The images of the funerals held by the human fleet for the soldiers who died in the war not long ago are still fresh in my mind.

At that time, the former Speaker of Parliament personally ordered that March 1st of each year be designated as Memorial Day for those who died in the war against human civilization.

It is used to commemorate those soldiers who sacrificed their lives for human civilization in interstellar wars.

But no matter how grand the funeral or memorial, it could not bring back the lives of those soldiers!

Lü Yongchang let out a long breath.

It was as if he was trying to vent all the pent-up frustration in his heart.

"I have already come up with a solution to this."

As he spoke, he reached out and made a gesture in the air.

The holographic projection was quietly activated.
