Research Institute No. 2, main control room.

In front of the huge display screen, hundreds of Lukka scientists with short stature, thin limbs, and huge heads sat up, all of them looking at the new village-level spaceship in the display without blinking.

The village-level spaceship is currently moored in the interstellar dock, under Xiao Yu's Zuihou inspection.

Dozens of robots climbed up and down on this village-level spaceship, and after being busy for more than ten minutes, Xiao Yu received a signal that everything was normal.

Xiao Yu suppressed the excitement in his heart and issued the order to launch.

The tail of this village-level spaceship suddenly erupted with a powerful jet, and after a short warm-up, the intensity of the flames increased dramatically, and the powerful recoil force pushed the spacecraft to rush out like lightning.

"It has been accelerated for three seconds, the hull structure is normal, no deformation has been found, and the pressure sensor has not detected over-limit gravity."

Xiao Yu received a response and immediately issued a new order: "Continue to accelerate." ”

"It has been accelerated for thirty seconds, the hull structure is normal, no deformation has been found, and the pressure sensor has not detected out-of-limit gravity."

"Go on."

There is constantly information sent back, and Xiao Yu keeps sending new instructions. Slowly, twenty minutes passed, half an hour passed.

The speed of this village-level spaceship has reached 5,400 kilometers per second! This speed is almost twice as high as Xiao Yu's maximum speed before!

"It has accelerated for 1,800 seconds, the hull structure is normal, no deformation has been found, and the pressure sensor has not detected over-limit gravity."

"Can you still handle it? Good! Then keep accelerating! Xiao Yu suppressed his excitement and gave the order to continue accelerating.

Forty minutes have passed!

The speed of this village-level spaceship has reached 7,200 kilometers per second!

"It has accelerated for two thousand four hundred seconds, the hull structure is normal, no deformation has been found, alarm! The pressure sensor detects an out-of-limit gravity, and if you continue to accelerate, the hull may be destroyed! ”

"Whew......" Xiao Yu exhaled lightly, "Is the limit of continuous acceleration for 2,400 seconds?" 7,200 kilometers per second! That's tough enough. ”

"So, stop accelerating and go back." Xiao Yu gave a new order. Immediately, the flames in the tail of the village-level ship began to weaken, and finally slowly extinguished. The ship then made a postural adjustment and began to slowly reverse its acceleration towards the Aquila A base.

At this moment, within the Second Institute, hundreds of Lucca scientists have been plunged into a sea of joy. There they shouted and hugged loudly, celebrating this great victory.

At this moment, Xiao Yu had this thought: "Perhaps, if you cooperate with different races, technology will progress faster." Because of the difference in living environment and living habits, it may be a blind spot for this civilization, but it is easy for another civilization to think of. At least, many of the ideas of the Lucca scientist were enlightening even to me. Well, the idea is worth a try. If I encounter a technological civilization again, I might as well try to capture some scientists from their civilization and help me together. ”

Xiao Yu made up his mind.

At this moment, this village-level spacecraft has flown millions of kilometers away. When he came back, he was not in such a hurry, Xiao Yu controlled the spaceship, first slowed down slowly, and after the deceleration was zero, he began to accelerate towards Aquila A, and it took five hours to summon it back.

After the new spaceship entered the dock, Xiao Yu immediately manipulated the robot and examined it all over the body. The conclusion was that the new material withstood the enormous gravitational pull and was virtually undeformed during the acceleration of up to 40 minutes. The engine also withstood long-term high-power operation and did not burn out.

It's just that, after this coming and going, all the portable fuel of this spaceship has basically been consumed.

Suppressing the joy in his heart, after forcing Luca's scientists to take a three-day break, Xiao Yu announced the research topics that needed to be carried out in the next stage.

Now that the material technology problem has been solved, the next question is how to apply fuel more efficiently.

Before the research began, Xiao Yu received a report from Lucca scientists.

Through the video connection, an unusually old Lucca scientist in front of Xiao Yu said slowly: "Respected Spokesman of the Gods, under your leadership, we have overcome the problem of material technology, but you must know that this material called Liujin is extremely difficult to produce, even if our manufacturing power increases by a hundred times, a thousand times, it is still difficult to meet the requirements." During this time, we had a new idea. ”

"That is, to find naturally occurring gold minerals in the universe. I don't know if you noticed that the environment in which we make the flow gold is very similar to some of the environments in the universe. That's ...... Stellar core. ”

"Of course, we can't enter the stellar core, but the environment in the core of the giant gas planet has a certain similarity with the core layer of the star, so there may also be flowing gold minerals in the core of the gas planet. Moreover, at the end of stellar evolution, after a supernova explosion, it may also release the gold minerals at the core into space. Therefore, we recommend that you conduct prospecting activities at the above two locations. If we can find flowing gold in these two locations, we can solve the problem of insufficient production. ”

Xiao Yu's eyes lit up, and he couldn't help but think silently: "If you want to say so, there is indeed a possibility that there are flowing gold minerals in the core of the giant gas planet and in the cosmic dust...... However, even at the core of the planet, I don't have the ability to reach it. But...... In the interior of the planet, there may be convection, that is, the material at the core may come closer to the surface by convection. The radius of the Aquila A is 60,000 kilometers, and my spacecraft can probably dive to 5,000 kilometers. This plan is worth a try. ”

Xiao Yu made a decision, so he ordered: "This idea is very good, I will send a spaceship to explore the interior of Aquila A." Now, let's start with the issue of fuel efficiency. ”

"We're here to help." The old Lucca scientist bent down deeply.

In the following time, Xiao Yu once again saw the madness of Luca's scientists. This time, they went even further, and all the Lucca scientists didn't rest for ninety hours in a row. Even Xiao Yu couldn't help but sigh: "Can the fanaticism for religion reach such a level? ”

It wasn't until a Lucca scientist couldn't help but faint that Xiao Yu forcibly let them all go to rest. Even so, dozens of Lucca scientists shouted and refused to leave their jobs. This time, Xiao Yu had no mercy, and directly injected them with Lucca's special hypnotic potion and dragged them to rest.

At this time, the "Prospecting Type 1" spacecraft prepared by Xiao Yu had been built. The specially modified Prospect 1 spacecraft will be able to withstand pressures of up to 100,000 atmospheres and is expected to be able to dive 5,000 kilometers below the surface of Aquila A.

Inside the planet, Xiao Yu can get fuel replenishment at any time, so the endurance of this spaceship is extremely amazing. However, although the fuel problem has been solved, there is also the problem of the fatigue of the ship's hull, and each prospecting time cannot exceed fifty hours.

Once everything was ready, the Prospecting One spacecraft entered the interior of the Aquila A.

There is no significant separation between Aquila A and the interstellar medium. Xiao Yu took the place inside Aquila A, where the pressure reached one atmosphere, as the dividing line.

Once at this place, the thick gas has blocked out all outside light. Here, it is a world of violent air currents and infinite lightning. In the midst of the wind and thunderstorm, Xiao Yu controlled the spaceship and slowly descended.

Fortunately, Xiao Yu used quantum entanglement communication jishu, otherwise, in such an environment, any radio wave communication would be blocked.

The further you enter the interior of the planet, the warmer it becomes. Just 10,000 meters below the dividing line, Xiao Yu observed a magical phenomenon.

Inside the Aquila A, it's raining.

Because of the extremely low surface temperature of Sky Eagle A, hydrogen, helium and other gases will become liquid, and due to the increase in density, these liquid substances will pass through the dense atmosphere and fall inside, forming the miraculous rainfall phenomenon observed by Xiao Yu.

Dense raindrops hit the spacecraft with a crackling sound, and in the next moment, the raindrops were reconverted into gas by the temperature of the planet's interior, and began to drift towards the planet's outer layers again. In this way, inside the planet, a unique circulatory system is formed.

At this moment, Xiao Yu had already dived to a depth of twenty kilometers, that is, twenty thousand meters. The pressure here has reached the point of 500 times the pressure of the earth. This made Xiao Yu's heart worried. Because Xiao Yu found that his initial estimate was a little wrong, and the pressure there was likely to exceed 100,000 times the pressure of the Earth's atmosphere under the inner 5,000 kilometers of the planet.

Xiao Yu did not give up, but continued to dive, deeper and deeper, deeper and deeper, and now, Xiao Yu has reached a depth of two hundred kilometers below the dividing line.

The concentration of gas here has reached an extremely terrifying level, because the temperature has risen, the gas here is denser than water, but it still maintains the form of gas. Xiao Yu turned the spaceship's engine to thirty percent of its power, barely keeping the spaceship stable.

It was absolute darkness, and no visible light could penetrate two hundred kilometers of gas to shine here. In the darkness, Xiao Yu's spaceship, like a tiny fish, swam in a sea of gas.

Suddenly, with a bang, a bolt of lightning pierced the sky, illuminating a space of hundreds of kilometers.

Under the light of this lightning, Xiao Yu saw a magical scene.
