The function of the rune board is being discovered by scientific researchers in modern society a little bit, and the importance of Boss Ye is also increasing little by little.

Maybe when the scientists can't study it thoroughly, they will really put the stallion Dafa into action, so that Ye Jinyu's children can inherit the thunder and lightning ability.

Boss Ye, who is remembered, is very comfortable, and he is riding the wind and waves in a down jacket.

The ship flew in the clouds, and the short wings and several large oars at the bow and tail rotated at high speed, propelling the ship to fly forward quickly; Riding the whistling northwest wind, breaking the boundless cloud waves.

From time to time, a wave of clouds was stirred up, revealing the fields, mountains, rivers, and villages below, causing the passengers on the observation deck to cry out in shock.

The observation deck is a newly renovated facility, which is actually just a female wall sawed off and added to the railing, located on both sides of the control center, and is covered by cantilevered wooden covers to protect from the wind and rain. Not to mention, the effect of these covers added behind Li Chunfeng is really good, at least the windproof and rainproof functions are still there, let's just say that this wind is blown straight, not only by the large area of wind, but also by the speed of the spacecraft; And it's cold. Now covered by this eggshell-shaped lid, only rows of observation holes remained; Most of the wind is drawn away by the shell cover, and the person standing without being exposed to the wind is secondary, and the wind resistance is small, and the speed of the spaceship is 10% faster. The spaceship shell is covered with photovoltaic panels, and a thermal insulation layer is formed between the photovoltaic panels and the shell. As a result, the temperature inside the ship was at least a few degrees higher.

A few coal stoves were burned on board to keep warm, and the crew was wrapped in a few thick clothes; Not to mention the comfortable environment, at least it is much better than when Boss Ye took the spaceship for the first time. For complete isolation from the cold, go to the cabin below deck. The emperor, who had been frozen several times, separated the lower floor out of a few rooms and installed a thick layer of heat insulation for rest.

In addition to these external devices, the control system has also been improved. The control circuit of the propeller was integrated into the bridge by Li Chunfeng, and the entire bridge was sealed and surrounded by thick wooden boards, leaving only some observation holes that could be opened and closed, as well as the wireless camera head brought by Ye Jinyu to observe the surroundings.

The wisdom of the indigenous people of the Tang Dynasty should not be underestimated! It has only been so long since they had a spaceship, and they have already learned to improve the spaceship, and over time, Datang's spaceship shape will only become more and more aerodynamic and suitable for flying. In the end, it may be directly separated from the shape of the ship.

Wouldn't it evolve into a flying saucer? Ye Jinyu thought uncertainly.

Of course, the cosmetic changes are all petty; The real overhaul is still armament; Ye Jinyu remembered that when the ship was first put into service, there was no weapons and equipment on board; The first armed people to board the ship were the ones who boarded the ship in Liangzhou Mansion. It was these people who helped Li Jiancheng fight a war to destroy the country. Now, the ship is armed to the teeth.

There are ten bronze cannons of the long-range weapon on the deck, which can spray solid projectiles to attack fortifications, and can also spray small lead bullets to hurt people; When necessary, it can also be launched with some rocks and debris, and even erupts a small thunderbolt.

Needless to say, the special iron-bone iron-clad martial arts type 3 armor for the emperor's guards was equipped with twenty-four planes to press the bilge bottom. This thing can kill tens of thousands of Turkic people crying and calling for their mothers.

In addition to these two, there is also the divine thunder, hundreds of iron-hulled divine thunderbolts are placed at the bottom of the cabin, and the back of the butt of the ship is open, and it can be opened at any time to throw eggs underneath.

War is indeed the driving force behind the development of science and technology!

After the birth of the spaceship, the first evolutionary direction is to integrate all the advanced weapons into the ship, all for the sake of war!

Standing next to Ye Shenren was Li Yuan, the emperor of the Tang Empire, who was different from Boss Ye in a down jacket, Li Yuan was wearing a thick fox fur; The white fox fur and a snow-white sea of clouds shine together; Like the sea of clouds, the ups and downs are Li Yuan's surging heart. Whenever a weak spot in the clouds was revealed, he looked closely.

These are all my country!

After flying for a while without a gap in the clouds, Li Yuan couldn't help but ask:

"Shenxiao King, where is the spaceship at this moment?"

There was no road or map in the sky. If it was in the past, he would never dare to fly straight above the clouds like this, if he accidentally ran to that fire continent and earth continent, it would be a big trouble if he couldn't come back.

Fortunately, this time there is King Shenxiao, and Li Yuan can still ask.

But Li Yuan asked the wrong person, there was no altimeter, no speedometer, no GPS, no compass, and Ye Jinyu didn't know where this ghost place was. But this time he could ask someone; Ye Jinyu pulled open a shutter on the wall behind him and shouted into the cabin:

"Sun Xin, Sun Xin, come on! I'm looking for you. ”

Sun Xin, who was wearing the grass-green down jacket again, quickly rolled in front of several people.

"Your Highness! What's the matter? ”

"How fast are we now? Where did it fly? ”

"This ......" Sun Xin hesitated for a moment, then pulled open the shield that Ye Shenren had called him just now, and shouted inside: "Daoist Li, come here, let's calculate the latitude and longitude together." ”

Sun Xin is not confident enough to dare to love it, and he has to pull the scientist Li Chunfeng to measure the latitude and longitude.

As soon as Li Chunfeng came, he pulled Sun Xin up and went out to the top of the lower floor without saying a word, stood in a position where he could see the sky, and then took out a well-made sextant and looked at the sun.

The principle of this thing is very simple, and it is easy to do; During the Chinese New Year, Sun Xin asked the carpenter in the Shenren Workshop to copy one according to the figure. To build a sextant, you need mirrors and telescopes, so Boss Ye used the scrapped electric car waste and dismantled two rearview mirrors. Fortunately, the electric car is a bargain, and the mirror used in the rearview mirror is flat glass, with no curvature. Small telescopes naturally can't be brought, but there is a kind of stationery called magnifying glass and concave lens in the modern world. With these two things, plus a sleeve, you can make a simple telescope.

Li Chunfeng looked left and right, looked at it for a while, and then handed it to Sun Xin and asked Sun Xin to look at it too; Then the two discussed a few words and agreed on their opinions, before returning to Ye Jinyu and said, "Your Highness, what time is it now?" ”

Ye Jinyu looked at his mobile phone, it was more than 4:40 in the afternoon; But Boss Ye's mobile phone is Peking time, and the standard Chang'an time is more than forty minutes later than Peking time. That is to say, the capital time of Datang should be at four o'clock; has been in the Tang Dynasty for so long, and Ye Jinyu also knows how to convert the time.

"Half an hour to go!"

Li Chunfeng calculated for a while with his hands behind his back, and then said to Li Yuan, who was full of expectation: "Your Majesty, the speed of the spacecraft now is four hundred kilometers per hour, and after two hours of flight, we have already flown eight hundred kilometers, and we have changed to the old system, which is 1,600 miles." After comparing it with the map, he said: "According to the direction and speed, Qizhou in Henan Province has passed now!" ”

Boss Ye also silently calculated in his heart, an hour is two hours, and 400 kilometers is a modern kilometer. In other words, it is 200 kilometers per hour; It is not as good as a modern transport aircraft, but it looks like a helicopter, but the spaceship is much more loaded than a helicopter and can go farther.

In Ye Shen's heart, the speed of the spaceship was just barely enough, but to Li Yuan's father and son, it was like a thunderbolt.

Li Yuan knew that the spaceship had flown from Hanzhong, the capital of Liangzhou, to the Turkic royal court in one day, so he had a point in his heart about the speed of the spaceship. But even if I was a little mentally prepared, it was just heard, and today I really experienced the speed of flying from Gyeonggi Province to Henan Province in half a day, and I was still scared.

In fact, from Hanzhong to Kuqa County, where the Turkic royal court is located, the straight-line distance is 2,300 kilometers, starting from Hanzhong at about 7 o'clock in the morning, flying against the wind for 13 hours, and arriving at Kuqa County, where the royal court is located, at about 8 o'clock in the afternoon, and due to the time difference, Kuqa County in winter is seven or eight o'clock in the afternoon, which is exactly dusk. This time the speed was a few points faster; Four hours from Chang'an to Qizhou.

Li Yuan was mentally prepared and was taken aback, but Li Shimin was even more shocked.

"A thousand miles a day! That's a thousand miles a day! True artifact ears! ”

There is a god speed that can travel thousands of miles a day, and there is a god thunder that can break the city and kill the enemy, this is really a war artifact; And such an artifact, his father Li Yuan has already promised him one; As soon as he thought that he would have such an artifact in the Qin Palace, Li Shimin's heart became hot.

It's not that Li Shimin hasn't been on a spaceship, and Li Yuan has taken him with him a few times before. It's just that at that time, the owner of the ship, Li Yuan, was afraid that he would not be able to find the north and did not dare to let the ship fly too high, so he just dangled in the air of one hundred and ten meters where he could see the ground, so that he could quickly find his way home.

Thinking that he might get lost in the sea of clouds, Li Shimin couldn't help but ask: "Dare to ask King Shenxiao, how high did I fly?" ”

Even if there was an altimeter, Ye Shenren might not know it, so he had to go to see Sun Xin again; But Sun Xin didn't know very well. At this time, the captain of the ship, Su Lie, relieved his prince: "Back to the King of Qin, there are many high mountains in the Qinling Mountains, in order to prevent accidentally hitting the mountains in the clouds and mist, our ship flies more than 3,000 kilometers. It's just that people who are so frail at such a high level are often uncomfortable, and after identifying the dangerous mountains, our ship will descend to an altitude of 1,000 kilometers. ”

Hearing the collision with the mountain, Li Shimin nodded and asked again: "Flying above the nine heavens, there are clouds on all sides; How to determine the bearing. ”

This involves the sextant and the prime meridian, which Sun Xin has studied the most, so he knows best, so he stepped forward and said: "His Royal Highness the King of Qin, mark the earth with horizontal latitude and vertical longitude, then the earth is like a chessboard, and the longitude and latitude of the mountains and rivers on the chessboard and the roads of the city have a fixed number; We only need to calculate according to the time of the celestial phenomena to obtain our own latitude and longitude, which corresponds to the chessboard of the earth, and the direction of our position will be self-revealed. ”

Li Shimin understands the previous truth, but how to calculate his position?

Seeing Li Shimin's questioning, Sun Xin began to explain the importance of the sextant and the Chang'an Big Ben.
