Cataclysmic Era: I can unlock the tech tree

"receive."

A slightly stiff, electronically synthesized voice sounded, and a robotic arm slowly stepped forward, reaching out its "hand" to take the manuscript wrapped in an envelope.

Whether in the future or now, this manuscript will be a priceless treasure in the universe.

Watching the robotic arm leave the office, Lü Yongchang leaned back in his chair and let out a long sigh to relieve his fatigue from the past few days.

"Professor, Academician He's research on gravity shields has made a breakthrough."

"Currently, preparations for the experiment are underway."

"Hmm?!" Lu Yongchang raised an eyebrow, sat up straight, and laughed. "He Bilin is quite capable, breaking through the gravity shield so quickly."

As he spoke, he adjusted himself into a more comfortable sitting position: "Let me see the documents."

The holographic projection unfolded rapidly.

Research data on gravity shields was quickly presented to Lü Yongchang.

He reached up and touched his chin, quickly flipping through the information in the holographic projection.

"Countless miniature gravitational fields are generated outside the curvature bubble..."

Lü Yongchang smiled and nodded: "That's a good plan."

"It also has a significant advantage in micro-management."

As he spoke, he quickly flipped to the section on control procedures.

"As expected." Lu Yongchang laughed heartily, "I knew I hadn't misjudged this kid. He just modified the control program of the magnetic field shield and used it directly."

"Zero, when will the experiment begin?"

"One hour left," Zero replied quickly. "Are you going to the site to direct operations?"

Lu Yongchang pondered for a moment, then shook his head and said, "Let's wait."

"Close the office door and don't let anyone disturb me."

"Let me think about something first."

As he spoke, he closed his eyes.

……

Consciousness quickly arrived in the technology tree space.

Lü Yongchang frowned slightly.

Every time he saw the mottled background of the tech tree space, he would feel a sense of inexplicable irritation.

I have a feeling that since the last "upgrade," the tech tree system has been hiding some important information in the background.

But looking at the colorful, mottled background, he really couldn't figure out what kind of information this thing could hide.

After a moment's thought, he reluctantly turned his attention back to the luminous white technology tree floating in the air.

The branches and leaves are lush and the cursor is bright.

The technology tree of a Level 4 civilization is now fully formed!

A thin, luminous white line extended from the Grand Unified Theory, rising straight up into the mist above.

With a slight tremor, the mist gradually dissipated.

As before, the tech tree began to extend rapidly upwards amidst a slight tremor.

The vibrations gradually subsided.

The technology tree of a Level 5 civilization was also presented to Lü Yongchang.

The Grand Unified Theory, once considered the ceiling theory for a Level 4 civilization, has now become the cornerstone of a Level 5 civilization, quietly residing at the lowest end of the technology tree.

The pale white lines gradually extended upwards, slowly dispelling the thick fog and revealing faintly lit cursors.

Second-generation gravitational field control technology

Starship Adaptive Artificial Gravity Technology

【…】

A look of realization dawned on Lü Yongchang's eyes.

No wonder the Academy of Sciences encountered obstacles in its research on artificial gravity.

From the perspective of the technology tree, the prerequisite for achieving artificial gravity is a new type of gravitational field control technology guided by the Grand Unified Theory!

……

"Professor, Professor?"

He Bilin's voice came from the side, interrupting his recollection.

"What's wrong?"

Lu Yongchang snapped out of his daze and turned to look at He Bilin beside him.

"Professor, it's a success!" He Bilin's eyes were filled with excitement. "The first practical test of the gravity shield was a complete success!"

"Its strength is several times greater than that of the magnetic field shield."

"At the same time, it can also block kinetic weapon attacks to some extent!"

Lu Yongchang quickly looked at the holographic projection in front of him.

In the projected image, the small, experimental starship stood firm against the storm of attacks from the Golden Crow battleship.

"Current shield load is 53.9%."

"Preliminary estimates suggest that it would take three Golden Crow battleships to breach its defenses."

He Bilin quickly explained, "When combined with the magnetic field shield, our starship's defensive capabilities can be significantly enhanced!"

"Excellent! Excellent!" Lu Yongchang nodded in satisfaction as he looked at the rapidly flashing experimental data in front of him. "Once this is finished, I'll go and tell Academician Fang."

"I've had your application approved."

He Bilin was stunned for a moment.

The next second, his smile brightened even more: "Thank you, Professor Lü!"

After the celebration, He Bilin hesitated for a moment before speaking in a low voice, "Professor, um..."

"What's wrong?" Lü Yongchang looked at He Bilin in surprise. "Didn't you always want a robotic arm to... cough, for transportation?"

"What, you don't want it anymore?"

"No, no, no!" He Bilin's expression changed instantly. He shook his head quickly and said, "What I mean is, that Grand Unified Theory, could it be..."

Lü Yongchang looked up and scanned the area.

Seeing the expectant looks on the faces of the academicians in the laboratory, he burst into laughter.

"good!"

Smiling, he strode forward and said, "Then I'll give you a brief explanation of the Grand Unified Theory."

……

Human Union Starship Factory.

"Academician Cao, are you sure you need to reserve such a large amount of space for renovation?"

Li Yuntian frowned slightly, looking at the modification blueprints in the holographic projection, and asked in a low voice.

"This will greatly increase the burden on the starship factory."

"Most importantly..."

"If this level of modification is carried out, the fleet may need to set sail immediately to find resources."

Faced with the doubts of his juniors, Cao Liangcai did not get angry, but instead smiled and shook his head.

"These are all necessary components."

Have you seen the latest announcement?

Li Yuntian shook his head in confusion.

"The gravity shield technology has been completely overcome."

"Breakthroughs have also been achieved in warp drive technology."

"The human fleet can leave this hellhole at any time."

"Do you think Professor Lü will apply these new technologies to the starship before he leaves?"

As he spoke, Cao Liangcai sighed softly: "After all, no one knows what kind of situation humanity will encounter next."

"just in case……"

Li Yuntian's expression turned serious: "Academician Cao, I understand."

"Ding-dong."

A crisp notification sound rang out.

"Academician Cao Liangcai, Professor Li Yuntian, the Chinese Academy of Sciences has released the latest paper. Please check it as soon as possible."

"Paper published by: Lü Yongchang".

Cao Liangcai was stunned for a moment, then turned his head and exchanged a glance with Li Yuntian beside him.

They both noticed the confusion and surprise in each other's eyes.

"Grand Unified Theory!"

The two said in unison!
