It's reasonable for me to have a two-way foil for a second-level civilization, right?

……

With theoretical support, coupled with zero's terrifying work efficiency, the first gravitational shield test began soon.

A remodeled small starship slowly sailed away from the United Starship factory and flew towards the empty space in the distance.

A [Golden Crow] battleship silently followed behind it.

"Activate the gravitational shield."

He Bilin gave the order with a serious expression.

The power of the antimatter engine began to increase continuously, and several gravitational field generators installed inside the small starship began to operate.

While small gravitational fields are being continuously generated around the starship, a slightly larger anti-gravitational field is also slowly strengthening around the starship.

With the help of high-precision optical telescopes, it can be clearly found that as the power of the gravitational field continues to increase, the light passing through the small starship gradually becomes distorted!

"The gravitational shield was successfully generated, the current state is stable, the load is 3.73%, and the attack test can be started at any time!"

The sound of the report came from not far away.

"Prepare……"

Before He Bilin finished speaking, the door of No. [-] laboratory suddenly opened.

"Successful! I succeeded!!"

Lu Yongchang's ecstatic voice came from outside the door!

ps: add more! (5/11)

Dear readers, please send a free gift for love!

Chapter 657

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

"Success?!"

He directly dropped the work in hand, turned around and walked towards the door of the laboratory.

"Professor, please explain clearly, what succeeded?!"

He Bilin's voice trembled slightly, and he eagerly asked Lv Yongchang who was walking towards him.

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

Therefore, the moment he heard Lu Yongchang's words, a slight guess appeared in his mind.

Grand Unified Theory?

He couldn't believe his guess.

How much time has passed? !

The test machine of the gravitational shield has not been successfully operated yet, and Professor Lu single-handedly took off this crown of physics?

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

Lu Yongchang nodded with a gentle smile, raised his hand and patted He Bilin's shoulder lightly.

"Yes, you guessed right."

"Grand Unified Theory, I figured it out."

At the moment of hearing this understatement, He Bilin only felt his breath suddenly suffocated!

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

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

"You're really, really, really..."

His face flushed slightly, he held back for a long time, and finally came out with the simplest and most simple words: "It's too awesome!"

There was a brief silence in the laboratory for a few seconds, and then a burst of laughter broke out.

He Bilin scratched his head in embarrassment, quickly got out of the way, and stretched out his hand to lead: "Professor, please come in."

"Just right, the first test of the gravitational shield has begun."

"According to your instructions, this gravitational shield is developed based on the curvature bubble technology."

Lu Yongchang smiled and waved his hands: "I didn't point you out."

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

As he spoke, he strode into the laboratory with strides.

"Attention all units, the first live ammunition test of the gravitational shield begins now!"

He Bilin's excited voice came from behind.

Looking at the [Golden Crow] battleship whose muzzle began to shine in the holographic projection, Lu Yongchang felt a little bit of emotion in his heart.

His thoughts returned to ten minutes ago.

……

Inside the office.

Lu Yongchang's eyes flashed with extremely strong excitement.

He stretched out his hand to unfasten the electromagnetic adsorption device on the seat, and complained softly.

"just wait."

"When the Grand Unified Theory is settled, I will tear you down sooner or later!"

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

He gently opened the top door of the locker, and carefully took out a black box from it.

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

He gently brushed off the scattered dust on the black box, and quickly returned to the 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 airflow followed.

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

A pen with obvious wear marks on the surface appeared in front of his eyes.

Looking at this pen, Lu Yongchang's eyes suddenly filled with deep nostalgia.

……

This was a gift from Su Yutong in the Earth Era.

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

Naturally, he didn't care about this gift at the time, nor did he care about the date when the gift was sent.

He just regarded it as an ordinary gift.

until later.

When human civilization successfully left the solar system and had a little respite, Zero "woke up" him.

'Professor, according to the humanities information I have, you should return the gift to Professor Su Yutong. '

At that time, Zero said so.

'Return gift?Why return the gift?Does this gift have any special meaning? '

Lu Yongchang, who was lying in the hibernation cabin, asked Ling suspiciously.

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

'The time you received the gift is February 2th in the Earth calendar. '

Lu Yongchang was stunned.

But the effect of hibernin had already appeared, he slowly closed his eyes, and his consciousness gradually stagnated.

……

After entering space, because there is no gravity, traditional pens can no longer be used normally.

For this reason, he specially added an electromagnetic micro-pump to this pen.

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

Seeing that the pen was getting more and more worn out, and paper was a scarce resource in space, he had to seal it in a vacuum box.

Today it is today.

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

Lu Yongchang carefully took the pen out of 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 weight.

"Swish..."

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

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

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

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

In the universe, the theories and formulas that every fourth-level civilization dreams of are slowly taking shape on this light paper!

"despair."

The tip of the pen tapped lightly on the paper, leaving a tiny black spot.

"finished……"

Lu Yongchang took a deep breath and whispered softly: "Human civilization has become a fifth-level civilization at this moment!"

The moment he said the words, his eye sockets felt sour.

Thousands of years of hard work have finally come to fruition.

Weak human beings can finally send out their own voices to the universe today!

He was silent for a moment.

After turning his head to glance at the date, he waved the pen again and left a last sentence.

——On February 3276, 2 in the Earth's calendar, Lu Yongchang gave Su Yutong a gift in return.

He carefully closed the pen and put it into the black box again.

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

After putting the box back to its original position, Lu Yongchang reached out and removed the electromagnetic ruler, and picked up the thick stack of manuscript paper.

"Ling, help me deliver this manuscript to Academician Su Yutong."

"Tell her for me."

"This is my return gift, I kept her waiting for a long time."

Chapter 658 Level [-] Civilization!

"receive."

A slightly stiff electronic synthesizer sounded, and the robotic arm robot slowly stepped forward, and stretched out its "hand" to take the manuscript wrapped in an envelope.

Whether it is the future or the present, this manuscript will be a manuscript of great value in the universe.

Watching the mechanical arm robot leave the office, Lv Yongchang leaned hard on the back of the chair and let out a long sigh to relieve his fatigue during this time.

"Professor, Academician He's gravitational shield research has made a breakthrough."
