At the beginning of the design of Deep Blue's Night Owl No. 1, in order to make this behemoth rise into the air, even Eagle Sauce Country, which claims to have the world's most advanced engine technology, had to install eight engines on the hull.

So before the Night Stalker One crashed, it looked like a lumpy lump of iron.

Because most of the sides of the hull are occupied by engines.

And the first warship that the Great Xia Kingdom is now preparing to build that can take off into the air is very different from the Night Owl One.

Because Lu Chuan's goal is to borrow the powerful energy of the purple element, so that the hull can be equipped with the least number of engines possible to lift the battleship into the air.

Therefore, when the scientific research bureau designed the engine, it was determined in advance, and it would never let the first battleship have more than four engines.

This not only reduces the weight, but also improves the overall stability, and at the same time saves a lot of space on the battleship itself.

But in this way, the problem is handed over to Lu Chuan and the Scientific Research Bureau.

Because the requirements for the engine are much higher than those on the Night Owl No. 1.

When he learned that the engine drawings of the Eagle Sauce Kingdom were of no practical use to the Great Xia Kingdom, Lu Chuan had no hope for this pile of waste paper.

Only a small number of seemingly useful data are referenced.

And then almost from scratch it was all about scientific research and self-development.

Fortunately, the previous scientific research bureau helped the space center develop a super-power rocket propulsion system, so with the help of previous experience, this research and development process can be regarded as twice the result with half the effort.

So only a few months later, the Scientific Research Bureau came up with the first prototype of the engine that could be tested.

Although the Great Xia Kingdom now has tens of thousands of liters of purple fuel, due to the irreproducibility of meteorites, the purple fuel is also extremely precious to the Great Xia Kingdom.

For this reason, the industry requires the scientific research bureau to use only ordinary aviation fuel when testing the engine in the early stage.

However, this is not a problem, as long as the power of the engine can be accurately calculated when running on normal fuel, it is possible to calculate the power after using purple fuel.

When the engine was first tested, the results surprised everyone.

Because the first prototype developed by the Scientific Research Bureau, when it was tested with ordinary aviation fuel, the power had already reached the requirements.

In other words, the engine designed by Lu Chuan, even if it does not use purple fuel, only four such engines can be carried on the battleship, and it can already send the battleship into space.

But the downside is that ordinary fuel cannot sustain the long-term fuel needs of a spacecraft.

This is also the reason why Eagle Sauce Country dared to let Night Owl 1 into space after using Element 115.

The first few tests of the engine, after each test, Lu Chuan will upgrade the engine.

Finally, when Lu Chuan thought that the engine had reached perfect condition, he applied to the industry to use purple fuel for testing.

The vast industry immediately allocated one liter of purple fuel to Lu Chuan, but even this liter was completely enough for the engine to be tested hundreds of times.

Because when purple fuel is used, it must be mixed with ordinary fuel, otherwise if purple fuel is completely used, then the powerful energy contained in purple fuel is like a small nuclear bomb, and if you are not careful, it is not as simple as destroying the engine.

On this day, before the start of the test, in addition to Li Shengdong and the vast number of industries, many high-level personnel from the Great Xia Kingdom came to the scene.

At this moment, even Lu Chuan himself is not sure what the effect of the latest engine will be after using purple fuel.

So everyone at the scene was full of anticipation, looking forward to seeing the engine perform well enough.

After Lu Chuan ordered the staff to fill the purple fuel into the fuel tank, the large screen at the scene began the ignition countdown.

Everyone held their breath, because they all knew that if the test was successful, then the engine in front of them would be the first step for the Great Xia Kingdom to enter space.

The countdown on the screen came to an end, and with Lu Chuan's order, the engine immediately erupted with red flames.

Immediately afterwards, the red flame slowly turned into a pale blue.

This is because the temperature of the flame ejected by the engine is gradually increasing.

At this time, the engine power displayed on the screen is also rising.

At the same time, Lu Chuan explained through the microphone to the high-level personnel watching the scene.

"At the moment we are only using a third of the power of the engines, and if we had four of these engines on our warship, the value displayed on the screen would now be enough to send our warship into space."

When the high-level personnel at the scene heard this, they couldn't help but stand up and applaud warmly.

Because this already indicates that the Great Xia Kingdom has the ability to send warships into space.

However, at this time, something happened that Lu Chuan didn't expect.

Lu Chuan just ordered to continue to increase the power of the engine.

A few seconds later, I suddenly noticed that the flames ejected from the rear of the engine had turned a startling purple color.

The moment the purple flame first appeared, the value of the engine power on the screen immediately turned red.

This change made the high-level personnel on the scene nervous, and they all opened their eyes and looked at each other.

Because most of them thought that there was a problem with the engine during the test.

But only Lu Chuan and some scientific researchers were excited at this time.

Because they know that the red on the screen at the moment does not mean warning or danger.

It's because the power of the engine at the moment has exploded.

Including Lu Chuan, all the scientific researchers have not seen any engine in this world that can shoot purple flames.

Before that, people in this world judged whether the power of an engine was strong enough to see whether the flame of the engine was blue or white.

And purple is a color that no one dares to think of, because the purple flame can reach an astonishing 7,000 degrees Celsius.

Even as the engine spewed purple flames, the bracket holding the engine shook a little.

Seeing this, Lu Chuan immediately shut down the entire test system.

Everyone at the scene frowned.

But at this time, through the glass window of the control room, they saw that the scientific researchers inside were screaming and hugging excitedly.

Everyone wondered what was going on.

It wasn't until Lu Chuan came out of the control room that he announced to everyone: "It can now be confirmed that the engine technology of our Great Xia Kingdom is already the most advanced and powerful existence in the world. ”
