As the closest planet to the earth, the moon has always been accompanied by human life, which has aroused the reverie of countless people, who have guessed what kind of scenery there will be, and thus left all kinds of magical and magnificent beautiful legends. Even after the first human set foot on the moon in 1969 and personally confirmed that it was just an empty and barren planet, with neither a heavenly palace, nor a god, nor even a trace of living creatures, people's interest in it has not diminished in the slightest, but has only strengthened a little, and they are excited by its abundant resources and key location.

As a member of the human race on the earth, Ye Qiuli naturally also had an infinite yearning for the moon, and more than once imagined that the Chinese nation would take the lead in occupying the bridgehead of the human race on the earth to the vast universe, rise again among the nations of the world, and regain its former glory. As for going to the moon to see and take a look, he never imagined it, and at that time, as an ordinary person, this kind of thing was too far away from him.

However, fate is sometimes so wonderful that it is not expected by everyone. In the past, Ye Qiuli could only stand on the ground and look up at the distant moon, imagining a unique scene on the moon in his heart, and never thought that he would be able to go up and take a look in person one day. At this time, he personally built the "Red Rabbit" spaceship, and with the ability to land on the moon, he instantly pulled something that was previously out of reach in front of him.

With an infinite yearning for legends and stories, and with the boundless excitement of successfully realizing his dreams, Ye Qiuli piloted the "Red Rabbit" spaceship, and quickly crossed the sky like a lightning speed, flying straight to the moon, the only alien planet that human beings have ever set foot on. On top of that, in addition to the myths and legends that have been circulating for thousands of years, there is also the spaceship fuel that he desperately needs at the moment.

In fact, the reason why Ye Qiuli chose the moon as the first stop of the "Red Rabbit" spacecraft is not only to realize his dream of landing on the moon, but also to collect the helium-3 element widely present in the lunar soil. Helium 3 is a very good nuclear fusion fuel, when the fusion reaction with deuterium (hydrogen 2), not only the energy conversion efficiency is extremely high, but also the fusion process does not produce neutrons, the fusion reactor device does not damage, it is truly safe and pollution-free, it is definitely the most ideal nuclear fusion reaction, especially suitable for astronautics.

The miniature controllable nuclear fusion device designed and manufactured by Ye Qiuli is the type that uses deuterium and helium-3 as raw materials for fusion reactions. Therefore, if he wants to successfully fly out of the solar system and travel to other star systems a few light-years away, he must store enough deuterium and helium-3.

Deuterium has as many as 40 trillion tons of reserves in the earth's seawater, which can be extracted in large quantities, but helium-3 is not, the amount of helium-3 on the earth is very small, and it is not even enough for experimental use, and it is almost impossible to use it as fuel for nuclear fusion reactors.

However, helium-3 is scarce on the earth, but it is extremely rich in the soil of the moon or the atmosphere of Jupiter, and it can be collected in large quantities. The total amount of helium-3 resources in the lunar soil can reach 1 million to 5 million tons, and Ye Qiuli flew to the moon this time in the hope of collecting a large amount of helium-3 and using it as the main fuel for the "Red Rabbit" spacecraft to maintain the effective operation of the spacecraft, and also store enough quantities to support his exploration of the vast universe.

The ultra-fast speed brought by the fusion engine is indeed far beyond the imagination of ordinary people, starting from the earth's orbit, fully turning on a reactor, and accelerating at full strength, the "Chitu" spacecraft only took more than 30 seconds to fly to the lunar orbit. That speed is many times faster than when it flew out of the earth, and it is not on the same order of magnitude as the aerospace planes commonly used by all countries on the earth.

"We have reached the lunar orbit and are in orbit, please indicate the next step. After circling around the moon for several weeks, and finding that Ye Qiuli still hadn't given any new orders, the central intelligent light brain of the "Red Rabbit" spacecraft immediately sent out an inquiring voice seeking instructions.

"Observe the environment and prepare for landing. Hearing Zhi Brain's inquiry, Ye Qiuli quickly turned his thoughts back, gave the order to land, and then handed over the spaceship to Zhi Brain again for control, while he himself briefly calculated the movement speed of the spacecraft. Different from the general environment, the distance between the earth and the moon is long enough that the flight speed of the "Chitu" spacecraft can be completely detected.

Although Ye Qiuli is very confident in his design, there will be a little difference between the things on paper and the actual test, and they can only be determined after actual testing. In particular, one of the most groundbreaking features of the supership he built was its speed - an unimaginable speed, which could be measured by the speed of light, so it was not surprising that he cared so much about the speed of the "Red Rabbit" spacecraft.

"The distance between the Earth and the Moon is about 380,000 kilometers, which is the distance of more than one second at the speed of light. According to the design, after turning on a reactor, the Red Rabbit spacecraft can reach 10% of the speed of light, and the time it takes to fly from Earth to the Moon should be 10 seconds. Excluding the initial acceleration and final deceleration, the speed of the ship is basically up to the design requirements. After just a little calculation, Ye Qiuli quickly determined that the speed of the "Red Rabbit" spacecraft was completely in line with the design requirements, and it was definitely a veritable super spacecraft.

"Chitu, bring up the speed record after the ship starts. After roughly confirming that the "Red Rabbit" spacecraft designed and manufactured by himself had basically achieved his set goal, Ye Qiuli ordered Zhi Brain to call up the speed record of the spacecraft itself, and prepared to check it in detail again.

"Yes. After receiving Ye Qiuli's order, the central brain of the "Chitu" spacecraft quickly responded, and then displayed a line of speed records on the big screen in front of the cockpit, from the initial gliding speed, to the vertical ascent speed, to the speed when accelerating horizontally, the speed when crossing the Earth-Moon space, and now the running speed after entering the lunar orbit, there is everything, and a detailed speed curve is drawn below.

"Not bad! Not bad! The maximum speed has indeed reached 10% of the speed of light, but it's a pity that it has just been added and immediately slowed down, and the distance between the earth and the moon is still too short to play at full strength!" This very dazzling speed has fully met his design requirements, a single fusion reactor can already accelerate the spacecraft to 10% of the speed of light, and after all three reactors are turned on, it can definitely accelerate the top speed of the spacecraft to 33% of the speed of light!

1/3 of the speed of light, this is already a very remarkable achievement, in the earth science and technology community, I don't know how many years of hard work it will take to achieve! It's not that Ye Qiuli doesn't want to continue to increase, but in the process of interstellar travel, it is impossible for the speed of the spacecraft to increase indefinitely, and the physical law of this has long been recognized by mankind: the maximum speed of a rocket cannot exceed twice the speed of the material ejected from the nozzle of the rocket thruster.

Although the speed of charged protons, electrons, and uncharged neutrons in the fusion reactor may reach the speed of light, there is no fixed trajectory in their operation process, and if you want to use them to propel the spacecraft forward, it is definitely not possible to simply eject them directly, and the direction of their movement must be adjusted and controlled to make them spray back in a straight line. Naturally, after adjustment, the speed of most particles decreases as a result, and the extreme speed of the disorderly movement is no longer the same.

Not only that, but the flow of particles that change the direction of motion still can't directly propel the spacecraft forward, and needs to be adjusted again. Because of this method of spraying high-speed materials from the tail to propel the aircraft forward, in order to obtain enough thrust, it is necessary to use the turbojet method.

Just like ordinary rockets and jet engines, eddy currents are generated to slow down the movement of some molecules, which interferes with the linear motion of molecules, thus forming a resistance wall, and obtaining a better pushing effect with the speed difference of the molecules. In the same way, the engine of the spacecraft must also use particle vortex to rotate and decelerate some high-speed particles and form a blocking effect on the linear particle jet, so as to form a strong thrust.

In this way, after striking a balance between the thrust formed by the reaction force of the tail jet particle stream and the speed of the particle stream itself, the final ejected particle stream velocity is naturally greatly reduced, and the maximum speed of the spacecraft is also limited.

However, even if this is the case, the speed of light of 33% is completely enough for Ye Qiuli. After all, all he needed to do was fly the spaceship out of the solar system, to the Alpha Centauri star system, which was 4.4 light-years away from Earth, and find the teleportation array left by the ancient cultivators on the terrestrial planets inside it. After finding the teleportation array, he could naturally go to the distant cultivation realm through the teleportation array, without needing to fly slowly.

The cultivator's long-distance movement through the teleportation array can be directly transported through space, which is many times faster than simply flying in a spaceship! At that time, the "Red Rabbit" spaceship he created will basically be able to retire.

In fact, if it weren't for the fact that the teleportation array on the earth was destroyed because of the cultivator war, Ye Qiuli wouldn't have had to go to other planets to borrow the teleportation array so much, and now he could leave the earth through the teleportation array and directly find a way to the cultivation realm. He had heard Lu Yan say that if the teleportation array on Earth was still intact, it would still be able to contact many alien planets through it.

And once the teleportation network composed of different teleportation arrays is successfully entered, the path ahead for the cultivator is wide, as long as this network can reach the place, the user can teleport to it very easily, even if there is an occasional interruption of teleportation in the middle, they can also find another way, take a roundabout turn, and there will not be many situations like the earth that are completely isolated from the external cultivation world.
