After feeling the familiar movement deep in his mind, a hint of joy flashed in Lu Yongchang's eyes.

This feeling...

The technology tree space has been upgraded.

At the beginning, Lu Yongchang was a little worried when he looked at the test starship that was racing out like a wild horse.

After all, the success of the antimatter engine project requires testing in all aspects before conclusions can be drawn.

But now, Lu Yongchang completely put down his high-hanging heart.

The reason is very simple. As of now, the science and technology tree space is the most accurate, and it is the standard for judging whether key scientific research projects are successful!

Thinking of the technology in the Level 4 technology tree, Lu Yongchang felt infinite expectations in his heart.

He suppressed his inner excitement, turned his head calmly to look at Fang Xu beside him, and called softly: "Brother Xu."

"Um?"

At this time, Fang Xu's face turned slightly red and his face was full of smiles.

Apparently, he was delighted with the successful operation of the antimatter engine.

But even so, after hearing Lu Yongchang's call and seeing the slightly serious expression on Lu Yongchang's face, he immediately restrained the smile on his face and looked at Lu Yongchang with a slightly solemn expression:

"Is there any problem?"

At this moment, Fang Xu even prepared to stop the antimatter engine urgently.

Looking at the solemn expression on Fang Xu's face, Lu Yongchang laughed in silence: "Don't worry, there is no problem with the anti-matter engine."

"I want to go and have a rest." Lu Yongchang stretched out his finger and pointed to the office in the distance, "You will be in charge of the next experimental project."

Fang Xu subconsciously glanced at Lu Yongchang's pair of dark circles of eyes.

Indeed, during the final development stage of the antimatter engine, Lu Yongchang, as the project leader, had almost no rest time.

Now the experiment has basically been successful, so it is also appropriate to take a break.

Thinking of this, he quickly looked straight and nodded with a serious look: "Don't worry, just leave it to me."

...

After returning to the office, as soon as his body was touched on the chair, Lu Yongchang couldn't wait to close his eyes.

Consciousness instantly entered a fluorescent green space.

Like the previous promotions, the bright white thin line continued to extend upwards, and the invisible diaphragm between the third-level civilization and the fourth-level civilization was quickly broken through!

As the fluorescent green technology tree space continues to vibrate, Lu Yongchang's perspective also quickly moved up.

The technologies that I have studied flashed by in front of him like a revolving lantern.

Lu Yongchang's attention was not attracted by these "passers".

Since entering the technology tree space, his eyes have been staring at the dim cursor at the top.

After the bright white thin line broke through the barrier of the fourth-level technology tree, it quickly spread to the dim cursor.

【Antima Engine】

The cursor gradually brightens.

A thin white line of slightly dull white stretches extend out from it, stretching upward like a tree.

【Preliminary use of antimatter: antimatter bomb】

【High-energy gamma beam cannon】

【…】

In addition to these slightly dim cursors, there is an already bright cursor that attracted Lu Yongchang's attention.

【Antima Factory: Primary Dyson Ball Manufacturing Technology】

As Lu Yongchang turned his attention to this bright cursor, techniques quickly emerged in his mind.

After browsing, Lu Yongchang's "looking" suddenly became strange.

This... isn't this the Dyson Cloud and Dyson Ring system that humans have completed halfway?

No wonder there was no reminder when the technology tree space was completed.

It turns out that they have taken a shortcut and illuminated the techniques that the level 4 civilization needs to master in advance.

Lu Yongchang took back his thoughts and extended his attention as much as possible, trying to see more advanced technology clearly.

【gravitational……】

After spending a lot of energy, he finally only saw these two words clearly.

Even so, Lu Yongchang's heart was still hot.

Is it gravitational control technology?!

Thinking of the performance of the Lator civilization flagship on the battlefield, Lu Yongchang immediately became firm in his guess.

It seems that we have to seize the time to climb to the basic technology of level 4 civilization!

...

The main star Glitzer 555 is near.

Engineering ships are connected to each other, forming a simple giant space factory.

Its main function is to process various building materials transported by the [Taotie] material reserve ship, thereby creating a huge Dyson cloud with one side.

With the end of the Dyson Ball Phase 1 project, these giant space factories built from the hull of the engineering ship also disintegrated.

"incredible……"

Inside the Xuannv No. 2, a person in charge of transporting personnel, Wang Mingyuan pulled the porthole and exclaimed in a low voice: "I didn't expect that humans have developed to this point..."

"It's like watching a movie!"

The next moment, a strange male voice came from beside him.

"Brother, hibernation awakening person, right?"

Wang Mingyuan turned his head and looked in the direction where the sound came.

"You are..." He asked carefully in the face of his strange face.

It was not that he was timid, but that within a month after waking up, he found that there were big men everywhere around him.

Because of the problem of the awakening mechanism of the hibernation personnel in the Human Resources League, those who wake up before him are all hidden "gods".

You never know whether the old man walking on the streets of the city is a researcher from the Academy of Sciences or a senior member of the parliament.

"I?"

Faced with Wang Mingyuan's careful inquiry, the man chuckled: "I am responsible for the second phase of Dyson Ball."

"Hiss!" Wang Mingyuan subconsciously gasped.

Damn it!

This is really a big shot!

"How much do you know about Dyson Ball Phase 2 project?"

The man asked casually with a relaxed expression.

"The main purpose of the Dyson Ball Phase 2 project is to build 30 to 50 Dyson rings surrounding Glitzer 555 to increase the output efficiency of the antimatter production base, and at the same time lay the foundation for the Dyson Ball Phase 3 project..."

Wang Mingyuan calmed down and explained in detail.

“The basics are good.”

Hearing Wang Mingyuan's detailed answer, the man nodded with satisfaction, then raised his wrist and looked at the watch: "Large Engineering Architect..."

"How do you think this first Dyson ring should be built?"

Wang Mingyuan's breathing was slightly suffocated.

"Don't be nervous, just ask your opinion casually." The man saw Wang Mingyuan's nervousness and said with a smile, "It's okay if you answer wrong. After all, only a few people know the specific construction plan at present."

Wang Mingyuan swallowed gently, then raised his hand to wipe the cold sweat that oozed from his forehead.

Oh my god, I've fought hard.

What if I get the answer right?!
Chapter completed!
