How far is the Earth from the Sun?

150 million kilometers!

There are eight planets in the solar system, of which Earth is the third planet, and there are Venus and Mercury in front of it.

Among the eight planets in the solar system, the closest to the sun is Mercury, but the straight-line distance between Mercury and the sun has also reached about 58 million kilometers.

And, because it is so close to the Sun, Mercury is already scorchingly hot, with an average surface temperature of 179°C and a maximum of 427°C.

Ordinary people simply can't get close, even monks who are extremely adaptable to the environment, and without special training, they can't survive on Mercury at all.

However, while Fang Yun was diligently practicing the Sunset Bow Technique, he had already quietly begun to arrange on Mercury.

Fang Yun put the nano Xuan Ice obtained from the Li Dragon as fuel into the Emperor Boat, selected the elite of the Wild Wolf Battalion, and led it by Huang San, Zhong Keyi, Ledham, Leng Linwei and other monks, and quietly drove the Emperor Boat towards Mercury.

Mercury, in ancient Chinese mythology, is called "Dawn Star" or "Evening Star".

The Emperor Ark is the pinnacle of Fang Yun's own casting, using the liquid light technology of the Mayan civilization, theoretically having the third cosmic speed to fly out of the solar system.

However, in reality, due to the influence of the gravitational pull of the earth and the gravitational force of various celestial bodies, the real speed of the emperor boat is difficult to exceed the sub-light speed.

However, it was enough for the Emperor Boat to fly to Mercury.

Moreover, because of the particularity of quantum, the emperor boat flew to Mercury and began to build an underground base, and it was able to maintain special communication with Cloud City, so Liang Xiaoying's team launched a detailed study of Mercury to provide more technical support for the Mercury base.

At the beginning of the Great Xia Period, the number of human races in the world has plummeted, and even now, the population size has not reached one-tenth of its peak.

So, for now, there is no pressure on human beings to live in space.

But in the long run, as long as the human race on Earth can survive the Great Xia period and the population size begins to grow dramatically, then sooner or later, human beings will have to colonize terrestrial planets.

Mercury, on the other hand, is a terrestrial planet.

Mercury is much smaller than the Earth, the temperature is too high, the temperature difference is too large, and it is not suitable for human habitation, but, theoretically speaking, any terrestrial planet has an environment that is not suitable for human survival, and if humans want to complete colonization, they must master environmental modification technology.

Now, Fang Yun wants to set the sun with his bow and send the advance team to Mars, and Liang Xiaoying is just collecting a large amount of first-hand information to accumulate experience for human beings to transform the environment of terrestrial planets in the future.

In fact, after Fang Yun brought back the Mayan bronze casting technology and refined a small sub-light bronze spaceship, Yun Cheng already had the ability to explore outer space, at least, as long as there was enough energy support, Yun Cheng was fully capable of exploring several terrestrial planets in the solar system.

Fang Yun asked the wolf warriors to go to Mercury to build a base, but in fact, he also had the intention of exploring terrestrial planets.

After all, the Wolf Warriors are strong, their ability to adapt to the environment has been greatly enhanced, and with the protection of the Emperor Boat, they are relatively safe under normal circumstances, and they can collect a lot of useful information for Cloud City in the process of Mercury's adaptation to the high temperature environment.

Chang'e is a Hou Yi Taoist couple, and she should have the deepest understanding of Hou Yi shooting the sun back then.

In the process of communicating with her, Fang Yun found that her heart was always full of a faint melancholy, and there was a sense of resignation.

Even if Fang Yun had already recast the Sunset Bow, and the recast effect was good, even if Fang Yun practiced the Sunset Bow Technique for a long time and entered the realm considerably, however, Chang'e was still not optimistic.

In other words, in Chang'e's view, the sunset is difficult against the sky.

Thinking about it, Fang Yun also understood that the ancient powerful cultivators, like Hou Yi, were all peerless figures, and the feats they had accomplished were almost difficult for future generations to replicate.

For example, Nuwa seals the power of heaven and earth!

Even Fang Yun, who had obtained the Great Seal of the Five Elements, could not repeat this supreme feat at all.

Then Yi shot the sun, I am afraid that it is also a level of difficulty similar to that of sealing heaven and earth, Fang Yun don't want to complete it easily.

However, after thinking about it carefully, Fang Yun found that he might have some special advantages compared to Hou Yi.

For example, the blessing of modern technology and the civilization of the Great Western Continent.

These are all conditions that Hou Yi did not have back then.

Back then, Hou Yi just shot down the golden crow on the earth.

And Fang Yun can choose to fight on Mercury now, and he is not much closer to the sun.

What's more, Hou Yi was fighting alone back then, even if it was Chang'e, it was just an auxiliary force around him, and it was difficult to help him too much for his feat of shooting the sun.

However, Fang Yun had a huge advantage, Fang Yun was surrounded by wolves, and Fang Yun was able to invoke the power of wolves to improve his combat effectiveness.

Moreover, Fang Yun has a 5,000-year history of Huaxia, and the bow shooting techniques in history are endless, perhaps these bow shooting techniques are not as strong as Hou Yi's sunset bow technique, but there are many principles that can be borrowed, Fang Yun's magic shooting technique may be developed on the basis of inheriting the sunset bow technique.

For example, the Sunset Bow Technique is practiced by Fang Yun standing on the ground and stretching his bow.

However, as far as Fang Yun knew, the technique of bow archery, in addition to the standing bow technique, also included the technique of riding and archery.

Back then, Genghis Khan's iron cavalry used the art of riding and archery to conquer the world.

The wolf warrior is Fang Yun's mount.

The technique of riding and archery will also give Fang Yun a huge blessing.

These are Fang Yun's advantages, Fang Yun wants to maximize his advantages, and strive to shoot the Nine Golden Crows into the void within ten years.

In other words, Fairy Chang'e's faint resentment, that kind of demeanor that seemed to distrust Fang Yun, also aroused Fang Yun's arrogance.

Don't believe I'll be able to shoot down the Golden Crow in ten years, right?

Then I'll shoot it down for you in ten years!

There was still about a year or so before the ten-year period, Fang Yun's Sunset Bow Technique had already cultivated to the expected realm as scheduled, and the sun and moon were parallel, the Ten Thousand Miles of Dead Moon, and the One Arrow through the Sky had already been able to merge into one, turning into the final "Sunset Arrow". ”

Fang Yun said goodbye to Chang'e, and in her surprised expression, she broke through the sky and headed straight for Mercury.

When the monk cultivates to the Jindan stage, he can take off his physical body and fly in the air, and his speed of flying in the sky has greatly increased.

However, even if one cultivated to the height of Fang Yun, it was still extremely difficult to break through the shackles of the earth, that is, to break through the second cosmic speed.

Normal people, even if they are extremely powerful athletes, have a limit running speed of more than 100 meters and 9 seconds before the Great Xia Era.

An athlete who can break through less than 10 seconds can be called a flyer.

The second cosmic velocity is 11.2 km/s.

The difference between 100 meters in 9 seconds and 11.2 km/s is really incomparable.

Fang Yun was like an iron man, his hands were placed on both sides of his body, his whole body was covered with thick Great Wilderness silicon armor, driven by the Great Wilderness Battle Qi, the Great Wilderness Battle was full of blood, and his entire body turned into an airship, like an arrow, rising from the surface of the moon.

With a whoosh, Fang Yun was like a comet, dragging his long tail, and in Chang'e's gaze, he instantly got rid of the shackles of the earth and the moon and rushed into the vast space.

Piloting the flying machine to fly in the void and the body to take off, flying into the void were completely different things, and with the extremely fast speed, Fang Yun only felt that the Great Wilderness Silicon Skin had already burned, and the surrounding space was unprecedentedly cold.

Fire and ice.

Entering the vast space, completely weightless, it was difficult for ordinary people to control their direction at all, and Fang Yun also had a feeling of dismay, where his hands and feet were completely unfocused.

A complete loss of direction.

Of course, Fang Yun had Liang Xiaoying's special quantum communication device in front of him, which could guide Fang Yun in the right direction, and let Fang Yun avoid the orbit of Venus, so that he would not be captured by Venus halfway.

Even if Fang Yun turned himself into an airship and drove the Great Wilderness Battle Qi with all his might, the maximum speed of flying in the solar system could only reach about 5,000 kilometers per second.

Beyond this speed, Fang Yun would have a feeling of loss of control, dizziness, and an unimaginable difference from the sub-light speed of 250,000 kilometers per second.

According to Liang Xiaoying's calculations, the distance between the Moon Palace where Fang Yun took off and Mercury was about 120 million kilometers. In other words, Fang Yun maintained his highest flight speed, and it would take about 7 hours to reach Mercury.

Of course, because Mercury also has an atmosphere, Fang Yun must slow down after approaching, so the actual arrival time of Fang Yun is more.

It took more than 10 hours of flying for Fang Yun to see Mercury from afar, and it took another two hours for Fang Yun to see Mercury from the void, which was very similar to the moon.

On the surface of Mercury, there are also many craters, many craters.

If it weren't for Liang Xiaoying's special marking, Fang Yun would have thought that he had run to the moon again.

What made Fang Yun feel extremely surprised was that above Mercury, there was actually an aura that was even more abundant than the Moon Palace, which was of great benefit to cultivation.
