When the fire of the meteorite group was finally extinguished, Zhen Fei led the warriors into the meteorite group and swept it away, the materials left behind by these collision sites were all precious, after the refining of the fire of more than 5,000 degrees, everything that existed was the essence part.

Sun Yingji was very happy and said to the researchers under his command: "We are really blessed to have picked up the remains after the collision, and we can use these remains to create a new type of warship." ”

She was right, the meteorites she had brought back from the meteorite swarm had found at least three metals that had never been seen before, one of which was more inert than gold. It means that it is not easy to be dissolved or reacted by other elements, and Sun Yingji calls it a "lazy worm". Another metal is too active, but its melting point is very high, named "swan" by Sun Yingji, and the other metal is a little weird, after fusing with iron, the hardness of the material produced is about the same as cloud iron, but the new material also has the flexibility of plastic, which can be bent down with fingers. Sun Yingji called it "iron plastic", which means iron-like plastic.

If it can't be dissolved, it won't be easy to refine, and if the melting point is very high, it's not easy to be shaped to the desired shape. This made Sun Yingji scratch his head very much. Finally, it was calcined with six flavors of real fire, and after more than half a year, a divine furnace for refining utensils was created.

This divine furnace is more than 50 meters high and more than 200 meters in diameter.

On the day of the completion of the divine furnace, Zhen Fei also came to the scene and said in surprise: "Wife, you are not mistaken, right?" Hundreds of millions of tons of meteorites, you got me such a broken thing? ”

"You don't know how not to talk nonsense, what is a broken thing? My Sun Yingji hasn't produced anything broken yet. ”

"What's it called?"

"Divine Furnace." Sun Yingji said proudly.

"Where is God?"

"Its temperature can reach about 4,000 degrees, and it can automatically produce three times the atmospheric pressure, which is highly efficient for refining items, with this divine furnace, we used to increase the speed of a furnace to produce a king ship ten times a month, and we can produce a king ship in three days."

"So, the quality of the king ship still can't be improved?"

"The king ship has reached the top stage of the artifact, resistant to blows, low temperature and high temperature, resistant to thermal expansion and contraction, these qualities are several times that of the battleship in the dark world, fighting the battleship in the dark world again, just use the king ship to collide, you can knock down those broken battleships, are you still not satisfied?"

Scratching his head, Zhen Fei said: "It's still a little short of the ideal level in my heart, I want a battleship that is invincible in the starry sky." ”

"That's impossible, the starry sky is too vast, besides, we have been walking for almost three years, and we haven't encountered an enemy, and I don't know if the king ship is the best warship."

Sun Yingji seriously considered Zhen Fei's opinion, and she produced a landing ship. Since they need to enter the planets frequently, and each planet is surrounded by an atmosphere, the king ship will encounter resistance when it encounters the atmosphere, and this resistance slows down the king ship.

Since the slowdown is the result of the friction between the air and the exterior of the kingship, as long as the appearance of the kingship is extremely smooth, if there is no friction, there will be no resistance. But how to eliminate resistance is something that countless scientists are scratching their heads.

The only way to do this is to use a smoother material. The best material is glass.

Generally speaking, the glass is produced by the method of "liquid spread", that is, the material of the glass is formed into a liquid at a high temperature of about 900 degrees, and then spread on the top of the tin, because the surface of the liquid is smooth, the glass produced is also smooth.

Sun Yingji's method is called "air compression", which uses a smoother vacuum to press the glass material into the desired shape.

The advent of vacuum glass has brought about obvious changes. The specific production process is to deliver oxygen to the furnace in a vacuum, everyone knows that oxygen is a combustible substance, after having oxygen, the furnace fire will burn, and there is no gas and dust in the vacuum.

As a result, the glass produced reached the smoothest level, and Sun Yingji mixed yellow essence and lazy worms into the new glass, which she called "auspicious".

Geely neutralized the sloth worm and yellow essence, and fused it with silica.

The new style of glass has the smooth properties of glass, but also the hardness and flexibility of metal. Because the yellow essence is too precious, Zhen Fei is still not satisfied, the price of one gram of yellow essence is enough to exchange for a ton of gold, and the battleship made in this way is more than ten thousand times that made of pure gold. It's purely the style of a loser.

Sun Yingji could only continue to research and experiment, and finally she discovered that another metal iron plastic and silicon dioxide were fused together to produce a new material with the hardness of steel, the flexibility of plastic, and the smoothness of glass. This material is opaque, with the color of iron gray, which is more ugly, far less majestic and rich than the golden color of the kingship. The king ship has a kind of kingly air, and the color itself has a deterrent power.

This kind of warship is suitable for penetrating the atmosphere, and after testing, the speed of flying in the Imperial Flower Immortal Weapon reached a speed of 3,300 kilometers per hour, that is. The new landing ship is twice as fast as an airplane.

But this kind of battleship has a characteristic, when the temperature is above 2300 degrees, it will become soft, and at a higher temperature of 200 degrees, it will melt. This made it impossible for the ship to sail in the starry sky, because there were countless stars in the starry sky, and the temperature was often above 2,000 degrees Celsius on the side facing the star, and the side facing away from the star was often minus 200 degrees or 300 degrees.

As a landing ship, there is no problem, as long as it is not a planet far from the star, it can carry out planetary landing. Generally, the temperature of the planet is less than 1,000 degrees, and some planets can emit their own temperature.

The landing battleship was only fast in the atmosphere, the main thing was that it was very smooth, and the air resistance was infinitely close to zero. Flying in the starry sky, it is about the same speed as the king ship.

Then, for different environments, Sun Yingji studied two kinds of landing craft, fish-shaped and bird-shaped, which is the origin of bird ships and fish ships. Bird ships are suitable for flying in the sky, and fish ships are suitable for sneaking in the water.

If Zhen Fei had owned the fish ship early, the speed of crossing the Tianhe River would be at least three times faster.

After witnessing the collision, the samurai were more careful, and the observer handover time was extended in order to see farther into the starry sky. On this day, the observer found a green planet, and due to the distance, he calculated the volume of the planet and found that it was very similar to the earth described by Zhen Fei.

Hurry up and report it to Zhen Fei.

After the news spread, even Gao Gong and the others went to the deck to watch. In fact, no one has ever seen the Earth from the starry sky, and some people have seen photos taken on satellites. From the auspicious lens, it is indeed the appearance of the earth, surrounded by white clouds, blue water, and green vegetation.

Since most of the place is covered in white clouds, the coastline of the entire continent is not visible. Only a familiar coastline can be further confirmed.

It takes a week to get from the battleship formation to the planet, and the entire voyage is off course, which means that there can be danger. But the desire to go home is very strong, and no matter how dangerous it is, I have to go home.

The battleship formation slowed down, and after two days of careful observation, it was confirmed that there was no danger, Zhen Fei sent all the 19,000 people of all the guards divisions out, and when they captured the divine beast, they lost 1,000 people, this number was still missing, and there was no personnel to replenish.

There were more than 200 royal ships in total, divided into five echelons and flew all the way towards the green planet, and ten days later, the fleet arrived in the sky above this planet. Zhen Fei looked up, but did not find the shadow of the Big Dipper, and had a bad premonition in his heart.

It then orbited the planet and measured its circumference and distance from the north and south poles.

Zhen Fei has seen a piece of information, it seems that the earth is not round, like an uneven pear, and now looking at this planet, it is like an apple. Due to the cover of the clouds, it is impossible to see the whole picture, and it is necessary to send ships to conduct field investigations, especially to take some pictures in the places below the clouds.

This time, Zhen Fei decided to go down in person.

Some animals can be seen from the auspicious lens, and everyone thinks that there is not much danger. So Zhen Fei took ten companies composed of the Guards Division and drove ten bird ships to slide down in the direction of the planet's rotation, and from the direction of the planet's rotation, the gravity and resistance were relatively less.

When you enter the atmosphere, there is wind, and the air flow is the wind. The wind whistled from the outside of the battleship.

There is no close-range reference in the starry sky, and you won't find out how fast the battleship is at all, as the bird ship slides rapidly, Zhen Fei feels that the objects on the ground are rushing towards him, and hurriedly orders the warrior to slow down, reaching a speed of about five hundred kilometers per hour, which makes the bird ship really look like a big bird.

Beneath the clouds, fly above the most bulging equator, below the vast expanse of land and the coastline of white waves. After the bird ship flew along the coastline for two hours, Zhen Fei's mood became very bad, this is not the earth. Rather, it was a strange planet, and he did not see a single person and did not have the presence of a city. If it is the earth, even if it is in a deserted place, at least there is the existence of roads, ships in the sea, and airplanes in the sky.

Now, none of that is visible.

Since it is not the earth, Zhen Fei has no interest in staying any longer, and ordered: "Return immediately, this is not the earth." ”

The pilot shrugged his shoulders and increased his speed, and the bird ship rushed into the blue sky. Zhen Fei glanced at the sun in the sky and sighed: "This place is really too similar to the earth, but unfortunately there is no human habitation." ”

The thought moved: "The earth is overcrowded, and this is a planet that can be used as immigrants, and I haven't carefully observed the environment below, and I don't know if the temperature and climate are suitable for human habitation." ”

He was like an arrow, and he didn't want to delay any longer.

When he was responding to Tao Li and others, he was delayed for two months, and he was delayed for four months in the big collision, and he was unknowingly floating in the starry sky for three years.

After receiving Zhen Fei's order, the king ship outside the atmosphere was very disappointed, and immediately rearranged the formation and embarked on the road to the starry sky.
