The Reian Mountains, 100 kilometers west of Kyoto.

It is lush and full of tall pines and cypresses.

A low hill that looks like any other neighboring mountain.

But the interior is actually hollowed out, and the space inside is the size of three football fields!

This is the R&D base of the Dragon Kingdom rocket thruster!

In the entire hall of the base, there are three huge rocket thrusters!

And the usually busy scientific researchers, this will be nowhere to be seen!

If you look closely, on the east side of the R&D hall of the base, there is a steel door, about 10 centimeters thick, which is closed at this time.

Behind the steel door, there is a passage. After walking about 50 meters, there is another space.

It's not a huge space, but it's 300 square meters.

There are dozens of equipment and instruments hanging on the wall, each of one size!

This is the control room of the rocket thruster base!

At this time, all the scientific researchers in the base gathered here, and their expressions were nervous!

Long Lao stood at the front of everyone, staring at the main screen that had not changed anything!

"Chief Engineer Long, all preparations are ready, please give instructions!"

A staff member in a white research uniform reported back!

Long Lao took a deep breath, and then gave an order!

"Prepare for the fire!"

Hearing the order, the staff in front of the control table directly pressed the ignition countdown!

In the entire control room, the sound of the machine countdown sounded!

10、9、8、7、6、5、4、3、2、1。

"Ignition!"

At this moment, a huge thruster on the main screen immediately erupted red and yellow flames!

The reddish-yellow flame then turned yellow-white, and finally blue!

The huge high temperature directly scorched the pool below, and the white eyes rose one after another.

At this time, I saw that the thruster slowly left the control bracket and slowly floated in the air!

With a slight increase in fuel output, it will definitely break through to the top of the mountain and soar into the sky!

And then their experiment, not to let it fly out!

Long Lao gave an order to the operator!

"Fuel energy output adjusted by 50%!"

The operator heard the command and hurriedly controlled the fuel output of the thrusters to 50%!

The huge thruster, which was slowly rising, stayed in mid-air like this!

When all the scientific researchers in the control room saw this scene, their faces immediately showed joy, but none of them made a sound!

Because the experiment is not over yet.

Then Long Lao asked about the data of the thruster!

"Thruster injection fuel temperature?"

“1860°C！”

"Thruster inner wall temperature?"

“980°C！”

"Fuel line pressure?"

“102MPa！”

“……”

All the data is in the normal range!

Five minutes later, the data was stable!

"Fuel output settings are reduced by 3% per second!"

Then everyone saw that the rocket thruster fell slowly, and finally landed steadily on the control bracket!

The flame changed from blue to yellow-white again, yellow-white to red-yellow, and finally slowly extinguished!

The boiling water under the thruster also slowly returned to calm, and finally found that two-thirds of the 200 cubic meters of water had evaporated!

Long Lao's serious expression finally relaxed at this moment, he turned his head, and his excited hands trembled a little.

"We have successfully developed a 500-ton rocket thruster!"

As Long Lao's voice fell, the entire control hall suddenly cheered!

"We made it!"

"Haha! It worked! ”

"Great! Haha......"

“……”

Everyone was so excited, they were so excited!

After 5 years, they finally developed a 500-ton thruster!

Compared to the previous 300-ton rocket thruster, they have increased by 200 tons!

And at present, the level of aerospace technology has always been ahead of the beautiful country and Russia of Blue Star, and their rocket thruster is also up to 500 tons!

Dragon Kingdom squeezed directly into the first-class level of Blue Star on the rocket thruster!

This also marks a big step forward in the aerospace field!

Just as everyone was celebrating, Long Lao's expression suddenly turned white!

His assistant, Professor Li, found that Long Lao was holding his abdomen with both hands, and hurriedly stepped forward to support him and let him sit on the stool!

"Chief Engineer Long, are you alright?"

Long Lao slowed down for a while, and his pale face regained his blood color!

"It's okay! It's an old problem! ”

"This time our mission is complete, you must go to the hospital for a test, the last time you were asked to go, you kept shirking!" Professor Li said worriedly!

"Okay, I'll go to the hospital right away when I go back this time!"

"By the way, Xiao Li, you sort out the report materials, and I will go back to Kyoto today to report to the leaders above!"

"But, your body?" Professor Li said with some concern!

"It's fine!"

……

Kyoto!

Long Lao took the information and reported the situation to the senior leaders first!

Senior leaders were shocked. He couldn't believe it.

These days, the technology of Longguo is simply blooming, such as lithium iron phosphate power battery, ITER magnet material, 1 nanometer chip, he feels like a dream!

I didn't expect that the aerospace field, which had always lagged behind in the Dragon Kingdom, had also made a major breakthrough.

The rocket thrusters have reached the most advanced level of the Blue Star.

The senior leaders convened an emergency meeting of the senior leaders of the Dragon Kingdom.

After the meeting, all the senior leaders were excited and ready to announce to the world that Dragon Kingdom has made a major breakthrough in the field of aerospace!

However, the beautiful country announced it first!

[Professor Bai Yanlang led the team to develop a 700-ton rocket thruster! ] 】

When Long Lao saw this name, the anger that had been suppressed in his heart for many years suddenly surged into his heart.

The last mouthful of blood spit out and fainted directly!
