Before entering Tianhe, Zhen Fei did an experiment and shot a wooden plank with a sky-shaking bow.

The Sky Shaking Bow is a high-level magic weapon, and the planks are ordinary wood. This plank is ten meters long, thirty centimeters wide, and weighs forty-five pounds. It's all calculated. The Heaven-Shaking Bow was aimed straight at Tianhe, and the strength used reached a ton.

Based on all these figures, Qiao Bushi, who was far away on the mothership, was able to calculate some data.

From the auspicious and clear auspiciousness of the mothership, you can clearly see the trajectory of this wooden plank, at first it is still straight at the Tianhe, and it begins to tilt after flying about 20 kilometers, and then the angle of inclination gradually increases, and finally penetrates the water of the Tianhe River and goes downstream.

As far as the eye can see, the speed of the Tianhe River can be measured according to the speed of the plank.

How the heavenly river was formed, where the source is and where the end is, all this is a mystery for the time being. But there is a good analogy for the formation of the Tianhe. For example, using a water cannon to shoot fresh water on Earth.

If the power of the water gun is large enough, the fresh water fired must be straight forward, and if the water gun reaches the state of Infinitus, the water flow launched must be Infinitus. Moreover, water is material, although it is a compound of hydrogen and oxygen, but water has a density, which determines the attraction of a large amount of water when it gathers together, and this attraction causes the plank to deviate from its original trajectory.

On Earth, many units of measurement are made using fresh water. For example, one cubic meter of fresh water at normal pressure at room temperature is one kilogram, and the critical point between ice and water is zero. A green planet has a three-to-seven ratio of land to water, and a seven-to-three ratio of water to other substances in the human body. All of this is linked by mysterious evolutionary results.

Zhen Fei didn't have time to study these issues, as if these were left to the experts to draw conclusions.

According to the data calculated by Qiao Bushi, he decided the best direction to enter the Tianhe, the flow speed of the planks came out, and the Tianhe River did not have any obstructions, but with the strong attraction, so much water did not disperse in the starry sky.

It is necessary to save the resistance of the king ship, only to follow the flow direction of the river, and then do an inclined 25-degree angle of crossing, this direction is the most labor-saving crossing direction.

After preparing everything, Zhen Fei only prepared three king ships, ready to officially cross the Tianhe, and the angle of the three king ships is also exquisite, that is, the distance between each other is only two meters, at this angle, the vortex generated by the battleships in front when they advance is the most beneficial to the two battleships behind, and the battleships in the back will save energy.

This requires the pilots of the three ships to master the angle and speed of entry, not too fast, not too slow. The front one is a little harder, and the back is controlled to save energy as much as possible. Just like the geese migrating in the sky, flying in a herringbone formation is the most energy-saving.

Zhen Fei commanded the flagship to walk in the front, followed by two escort warships. Immediately drilled into the Tianhe, after entering, the driver did not dare to be a little negligent, set the direction of progress according to the angle pointed out by Qiao Bushi, and interspersed it in the oblique stab along the direction of the Tianhe River.

This is all done with the hints of Qiao Bushi.

The water of the river is very clear, and you can see about a thousand miles of space with auspiciousness. This shocked Zhen Fei's heart, such water quality is undoubtedly the purest fresh water in the world, without any impurities. But there is no expected water pressure, that is to say, at the bottom of the Tianhe, there is no gravitational attraction, if there is gravitational attraction, the water pressure will increase exponentially, without water pressure, it proves that this is a water flow through the starry sky, above, destined to have a height, below, destined to have a bottom. It's just that now they can't find the line between up and down.

But Tianhe is destined not to be so calm, from the auspicious lens you can see the swimming fish that you have never seen, as well as krill and other creatures, these creatures are relatively scattered, and you can only see one after a long time, but there are countless creatures in this Tianhe, this can be certain.

After entering Tianhe, the mothership could no longer see Zhen Fei's fleet, and the three cameras that Zhen Fei brought from the earth faithfully recorded everything he saw in the auspicious footage, and then sent it to the mothership in the form of radio waves.

Qiao Bushi and others saw the Tianhe footage equivalent to the live broadcast at that end.

What surprised Zhen Fei was that there was still light in Tianhe. Generally speaking, sunlight cannot penetrate thirty meters of water, and the water of the Tianhe River is endless, so where does the light in the river come from? It must be dark.

This subverts what he has learned before, and it seems that mysterious phenomena in the starry sky are everywhere. He couldn't find the source of the light, there was light all around, and he didn't know where it was coming from.

The king ship is moving at a speed of 300 kilometers per hour, which is equivalent to the speed of an earth ship at 160 knots. But the largest ship on Earth has a speed of 70 knots. And the range of this kind of speedboat cannot last, because the greater the range, the greater the fuel it carries, and the more fuel it consumes, too much fuel, too much weight, and also limits the speed. The vast majority of warships have a speed of around 40 knots, and the speed of aircraft carriers has reached about 38 knots, which is the fastest ship speed.

In other words, the speed of the king ship far exceeds the speed of ships on Earth.

Zhen Fei's heart was not very happy, on the contrary, it was very heavy.

With his intervention, the monk's level of science and technology has far surpassed the level of the earth's humans, and he hopes that he is not a sinner of the earth's humans, but a hero. But what will happen in the future, no one can say now.

But Zhen Fei ignored one point, they were drifting along the river, and the real speed needed to be measured in a static state of the water. The speed of the king ship is far from that fast, all thanks to Qiao Bushi, it is she who calculated that the king ship has reached the fastest state with such a speed.

After two days of sailing, a huge planet suddenly appeared in front of me.

Planets in the river?

Zhen Fei was about to freeze.

He quickly turned around to avoid crashing directly into the massive planet.

In fact, such a planet is just a grain of sand in a river, which seems to be huge, but in fact the river is bigger.

Quietly looking at the planet, it can be seen from the auspicious lens magnified 100,000 times. There are a large number of fish gathered on that planet, because there are mud and other debris on the planet, more small creatures are raised, big fish eat small fish, small fish eat shrimp, shrimp eat sand, this food chain is still eternal truth.

It stands to reason that the soil on the planet may float in the Tianhe, causing chaos in the water quality, in fact, what you can see from the lens is that the water of the Tianhe around the planet is still so clear.

The only explanation for this phenomenon is: "The planet in the river has a strong attraction, which makes it impossible for the soil on the planet to flow into the heavenly river." In other words, if the soil on this planet kept draining, I am afraid that it would have been dismembered by Tianhe long ago.

Water is buoyant, but the planet floats and sinks in the water, and maintains its own uniform rotation. It's amazing, and it's very unconscionable, but it's very reasonable. Because this planet may have been in Tianhe since the birth of Tianhe, for hundreds of millions of years, the planet and Tianhe have been integrated, compromised with each other, and interdependent, and their existence itself is the greatest rationality.

After secretly calculating, Zhen Fei found that this planet was the size of three Earths, and it took them a day to pass by the edge of the planet. During this day, Ji Xiang saw a lot of scenes that Zhen Fei could not forget, one of which was: "There is actually a creature on the planet that can stand up, with trembling gills-like organs on its cheeks, like a human looking at the direction of the king ship with a contemplative expression, but the fingers and toes of this creature have duck web-like links, which means that this creature comes from the aquarium." Zhen Fei was very skeptical that at such a distance, the human-like creatures on that planet had really discovered them.

Another shot is that Zhen Fei saw neat buildings on the planet, which means that there is civilization here. With technology and science.

There are more secrets seen in auspiciousness, all of which subvert the previous perception of the world by human beings. It turns out that a lot of human knowledge is wrong. We still know too little about the starry sky.

Zhen Fei felt that the harvest of crossing the Tianhe River this time was very huge, the Yin and Yang Trick made him open the Eye of the Sky, and the Tianhe made him open the Eye of the Starry Sky. If you don't enter the Tianhe, you will never know what is called the outer heavens. At this moment, Zhen Fei felt that Tianhe was the birthplace of the universe.

The planet he walked on was recorded by Zhen Fei, maybe he will never see this planet again in the future, the water of Tianhe is flowing, and after a few years, this planet will not still be here, I don't know where it has flowed.

But everything that is recorded will become valuable research data, and many scientists will benefit from it.

If it weren't for another task, Zhen Fei would have liked to study the Tianhe civilization more thoroughly and have in-depth contact with the local natives.

After ten days of sailing, I saw countless aquatic creatures along the way. Sometimes, you will encounter schools of fish that are not in sight, but can these fish catch food in such clear water? Zhen Fei was very skeptical.

Unbeknownst to him, the fish were actually migrating, similar to the antelopes and wildebeests on Earth, to breed their offspring in another place.

As the school of fish had an impact on the navigation, it hindered the way forward. Zhen Fei boldly opened the hatch of the king ship, and he made a backup: "If the king ship enters too much water, it is better to change to a king ship." ”

Then Zhen Fei entered the Tianhe, his bold move caught people off guard, especially Ling Yun, who immediately followed, the hatch was quickly closed, Zhen Fei saw that there was not too much river water in the cabin, only a very small amount of Tianhe water flowed into the cabin.

This shows that the seemingly powerful Tianhe water pressure is very small, there is simply no water pressure, and the water, as soft as the air on the planet, nourishes all the creatures in the Tianhe. Tianhe is like a gentle mother, looking at each child affectionately.
