Lu Yongchang's shouting made He Bilin's body tremble suddenly.

“Success?!”

He threw down his work and turned to the laboratory gate to greet him.

"Professor, please make it clear, what was successful?!"

He Bilin's voice trembled slightly, and he asked anxiously to Lu Yongchang who was walking towards him.

As a relatively core member of the Academy of Sciences, He Bilin naturally knew what Lu Yongchang did some time ago.

Therefore, the moment he heard what Lu Yongchang said, a faint conjecture appeared in his mind.

Great Unified Theory?

He couldn't believe his guess.

How much time has passed?!

Before the gravitational shield testing machine was successfully operated, Professor Lu took off the crown of physics alone?

"Big, great unification..." He Bilin swallowed hard and turned his expectant eyes to Lu Yongchang in front of him.

Lu Yongchang smiled gently and nodded, and raised his hand and gently patted He Bilin on the shoulder.

"Yes, you guessed it right."

"I've got it done with the great unification theory."

The moment he heard this understatement, He Bilin only felt his breath suffocate suddenly!

What followed was a ecstasy and excitement that rose from nowhere!

"How did you combine gravity with the other three forces!" He Bilin exclaimed repeatedly, "It's hard to imagine that you can complete this complex theory in such a short time!"

"You really, too, too..."

His face turned slightly red. After holding it in for a long time, he finally found the simplest and simple word: "So awesome!"

The laboratory was quiet for a few seconds, and then a burst of laughter broke out.

He Bilin scratched his head awkwardly, quickly moved out of his position, and reached out to inspire him: "Professor, please come in quickly."

"Just, the first test of the gravity shield has begun."

"According to your guidance, this gravitational shield was developed based on curvature bubble technology."

Lu Yongchang smiled and waved his hand: "I didn't give you some advice."

"This is your credit, no one can take it."

As he spoke, he took steps and walked into the laboratory.

"All units pay attention to the first live-fire test of the gravitational shield, now start!"

He Bilin's excited voice came from behind.

Looking at the [Golden Crow] battleship whose gun was beginning to shine in the holographic projection, Lu Yongchang felt a little emotion in his heart.

My thoughts then returned to more than ten minutes ago.

...

Inside the office.

There was an extremely strong excitement in Lu Yongchang's eyes.

He reached out and unbuttoned the electromagnetic adsorption device on the seat and complained softly.

"Wait."

"After I have completed the unified theory, I will demolish you sooner or later!"

While speaking, he got up and walked towards the storage locker beside him.

He gently opened the cabinet door on the uppermost floor of the storage cabinet and carefully took out a black box from it.

The box is not big, it is only slightly larger than the palm of your hand.

He gently brushed away the scattered dust from the black box and quickly returned to his desk.

"Click."

The sound of the electromagnetic adsorption device sounded again.

"call!"

Lu Yongchang took a deep breath and pressed a switch on the side of the black box with a solemn expression.

"laugh……"

The sound of air flow followed.

When the sound of airflow disappeared, he rubbed his hands and gently opened the lid of the box.

A pen with obvious wear marks on the surface appeared before his eyes.

Looking at this pen, a deep nostalgia suddenly rose in Lu Yongchang's eyes.

...

This is a gift from Su Yutong to him in the Earth Age.

It was the eve of the helium flash crisis, and he almost exhausted all his energy in order to lead mankind to escape from the earth and the solar system.

Of course, he didn't care about this gift at that time, nor did he care about the date of the gift.

He just treated it as an ordinary gift.

Until later.

When human civilization successfully left the solar system and was able to breathe slightly, Zero "awake" him.

‘Professor, based on the humanistic information I have, you should give a gift to Professor Su Yutong.’

At that time, Zero said so.

‘Return the gift? Why do you need to return the gift? Is this gift of any special significance?’

Lying in the hibernation cabin, Lu Yongchang asked Ling in confusion.

Accompanied by slight pain, hibernation was injected into Lu Yongchang's body, and Zero's voice also sounded.

‘You received the gift on February 14th of the Earth calendar.’

Lu Yongchang suddenly realized.

But the effects of hibernation have already appeared. He slowly closed his eyes and his consciousness gradually stopped.

...

After entering space, traditional fountain pens can no longer be used normally because of no gravity.

For this purpose, he specially added an electromagnetic micro-moving pump to the pen.

But the service life of the pen is limited after all.

Seeing that the pen is getting worn increasingly severely, and the paper in space is a scarce resource, he had to seal it in a vacuum box.ъìqυgΕtv.℃ǒΜ

Until today.

This pen that has spanned thousands of years was taken out again.

Lu Yongchang carefully took out the pen from the box and pulled out a stack of precious paper from the side.

He laid it flat on the table and flattened it with an electromagnetic ruler.

“Swishy…”

Writing in space is not an easy task, but he still struggled to keep his handwriting neat.

Accompanied by the rustling sound of the pen rubbing against the paper, lines of neat formulas appear on the paper!

At the same time, under real-time capture of the camera, the same content is also presented simultaneously in the holographic projection.

Zero's idle computing power was mobilized to this office in large quantities.

In the universe, the theories and formulas that every level 4 civilization dreams of slowly forming on this light paper!

"despair."

The tip of the pen gently tapped on the paper, leaving a small black dot.

“It’s done…”

Lu Yongchang took a deep breath and murmured softly: "Human civilization has become a level 5 civilization at this moment!"

The moment he said that, his eyes were filled with sourness.

After thousands of years of hard work, we finally achieved the right result.

The weak humans can finally make their own voice to the universe today!

He was silent for a moment.

After turning his head and looking at the date, he waved his pen again and left a sentence at the end.

——On February 14, 3276, Lu Yongchang gave Su Yutong back to him.

He carefully closed the pen and placed it in the black box again.

Accompanied by a sound of airflow, the inside of the black box was vacuumed again.

After putting the box back in place, Lu Yongchang reached out and moved the electromagnetic ruler away and picked up the thick stack of manuscript paper.

"Zero, help me give this manuscript to Academician Su Yutong."

"Tell her for me."
Chapter completed!
