"receive."

A slightly stiff electronic synthesized voice sounded, and a robotic arm slowly stepped forward, reaching out 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 considerable advantage in micro-operation."

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 applied it directly."

"Zero, when does 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 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 live-fire 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 weapons to a certain 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 defense 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. "I'll talk to Academician Fang after this is finished."

"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, get around with?"

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

"No, no, no!" He Bilin's expression changed instantly, and he shook his head quickly, saying, "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 walked forward and said, "Then I'll give you a brief explanation of the Grand Unified Theory."
