Chapter 516 Level 4 Technology Tree

After feeling the familiar movement deep in his mind, Lv Yongchang's eyes flashed with joy.

This feeling...

The technology tree space has been upgraded.

At first, Lv Yongchang was a little worried when he saw the test starship galloping out like a wild horse.

After all, the success of the antimatter engine project needs to be tested in various aspects before a conclusion can be drawn.

But now, Lv Yongchang has completely put down his heart.

The reason is very simple. As of now, the technology tree space is the most accurate standard for judging whether a key scientific research project is successful!

Thinking of the technology in the fourth-level technology tree, Lv Yongchang's heart rose with infinite expectations.

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

"Hmm?"

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

Obviously, he was happy about the successful operation of the antimatter engine.

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

At this moment, Fang Xu was even ready to stop the antimatter engine in an emergency.

Looking at the solemn expression on Fang Xu's face, Lv Yongchang laughed dumbly: "Don't worry, there is no problem with the antimatter engine."

"I want to take a break." Lv Yongchang pointed to the office in the distance, "You will be in charge of the next test project."

Fang Xu subconsciously glanced at Lv Yongchang's heavy dark circles.

Indeed, in the final research and development stage of the antimatter engine, Lv Yongchang, as the project leader, had almost no rest time.

Now that the test has basically been declared a success, it is also appropriate to take a break.

Thinking of this, he quickly straightened his expression and nodded seriously: "Don't worry, just leave it to me."

...

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

The consciousness instantly entered a fluorescent green space.

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

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

The technologies that he had studied flashed in front of him like a revolving lantern.

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

Since entering the technology tree space, his eyes have been fixed on 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.

[Antimatter Engine]

The cursor gradually became brighter.

Slightly dim white thin lines extended from it, stretching upward like a tree.

[Preliminary use of antimatter: antimatter bomb]

[High-energy gamma-ray cluster cannon]

[……]

In addition to these slightly dim cursors, there is a cursor that has already been bright and attracted Lv Yongchang's attention.

[Antimatter Factory: Primary Dyson Sphere Manufacturing Technology]

As Lv Yongchang turned his attention to this bright cursor, a series of technologies quickly emerged in his mind.

After browsing, Lv Yongchang's "expression" 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 in the technology tree space when this technology was completed.

It turns out that they took a shortcut and lit up the technology that the fourth-level civilization needs to master in advance.

Lv Yongchang retracted his thoughts and extended his attention upward as much as possible, trying to see more advanced technology.

[Gravity...]

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

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

Could it be gravity control technology? !

Thinking of the performance of the Latour civilization flagship on the battlefield, Lv Yongchang immediately confirmed his guess.

It seems that we have to hurry up to upgrade the basic technology of the fourth-level civilization!

...

Near the main star Gliese 555.

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

Its main function is to process various building materials transported by the [Taotie] material reserve ship to create a piece of extremely large Dyson cloud.

With the end of the Dyson Sphere Phase I project, these giant space factories built by the engineering ship hulls also disintegrated.

"Unbelievable..."

In a ship responsible for 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 just... It's just like watching a movie!"

The next moment, a strange male voice came from the side.

"Brother, hibernation awakening personnel, right?"

Wang Mingyuan turned his head and looked in the direction of the voice.

"You are..." Facing the strange face, he asked cautiously.

It's not that he is timid, but within a few months after waking up, he found that there are big guys everywhere around him.

Because of the problem with the Human Alliance's awakening mechanism for hibernating personnel, anyone who woke up before him was a hidden "god".

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 staff member from the parliament.

"Me?"

Faced with Wang Mingyuan's cautious questioning, the man chuckled: "I am responsible for the Dyson Sphere Phase II project."

"Hiss!" Wang Mingyuan subconsciously took a breath of cold air.

Damn!

This is really a big shot!

"How much do you know about the Dyson Sphere Phase II project?"

The man asked casually with a relaxed look.

"Dyson, the main purpose of the Dyson Sphere Phase II project is to build thirty to fifty Dyson rings surrounding Gliese 555, so as to increase the output efficiency of the antimatter production base, and at the same time, lay the foundation for the Dyson Sphere Phase III project..."

Wang Mingyuan calmed down and explained in detail.

"Good basic knowledge."

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

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

Wang Mingyuan's breath was slightly choked.

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

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

Damn it, I'll give it a try.

What if I get the answer right? !

At this moment, his mind was working fast.
