On the top of the fifth floor is the lookout area, where you can not only see from afar, but also the entire ship.

After climbing to this place with Li Chunfeng, Ye Jinyu said:

"Look at these blocks, they're a kind of solar photovoltaic device."

Following the direction pointed by Ye Jinyu, Li Chunfeng found that the five-fold eaves of the building boat, which were supposed to be equipped with glazed tiles, were all replaced with black glass-like squares, and there seemed to be wires connected between the blocks.

"Solar...... Photovoltaic power generation? What's the use of it? King Shenxiao said that it can generate electricity? Does it produce lightning like a lightning charm? ”

Li Chunfeng already knew that the battery dantian would be like the dantian on the person, and it would gradually run out of power after long-term use. When the battery is empty, the mecha can still be used with a new battery. The battery that is out of power will be handed over to Ye Shenren to be charged; As for how it was charged, he did not know. He didn't even know anything about charging, let alone generating electricity. Today he heard a new term about electricity.

"The truth is indeed this, solar energy and thunder charm both produce electricity, but the two are definitely not the same. Photovoltaic power generation is based on sunlight irradiation to generate electricity, this process is slow and continuous, and the generated electricity will be stored through the battery and then used for sail symbols, so that a steady supply can ensure that the charm is not interrupted. ”

"But this is not the case with the thunder talisman, it releases a huge amount of electricity in an instant, it is no problem to use it to blow up people, if you charge the battery, I am afraid that the ship will be destroyed immediately."

Li Chunfeng understood that this square glass plate was to turn sunlight into electricity. But he thought of a possibility and asked:

"It's just, what should I do if there is no day in the sky?"

Of course, Ye Jinyu can also think of this kind of question, and when he heard this, he smiled and pointed to the mast: "Do you see the things on the mast that keep spinning?" It's called a vertical axis wind turbine, and whenever there's wind, it spins. As long as the energy is in rotation, the current is continuously generated. ”

Looking at a few strings of wind turbines, Li Chunfeng could only sigh: "If it is a divine object, wind and light can be turned into electricity!" In this case, the ship should be able to travel far. ”

At this moment, I heard a craftsman running up and saluting: "Your Highness, the pattern on the cloth has been painted, do you want to apply tung oil immediately?" ”

"Painted?" Ye Jinyu was stunned for a moment, the talisman was brought over the day before, and now it is finally all brushed with cinnabar paint. "How long does it take to brush tung oil?"

"Back to Your Highness, it will take one day to brush the oil, and two days to dry; It takes three days to apply a layer of tung oil. ”

It takes three days to brush a layer of tung oil, which is too long, and the cloth charm is not sure if it can be used. Ye Jinyu thought about it and said to Li Chunfeng:

"It's better to choose a day than to hit the day, Senior Brother Li, it's rare for you to come back, it just so happens that you are here today, why don't we just have a preliminary test now." See if this talisman is viable. ”

Li Chunfeng is also a master who is afraid that the world will not be chaotic, and when he heard this, he hurriedly nodded excitedly and said, "Excellent!" ”

Ye Jinyu immediately said to the craftsman: "Don't coat the sail with tung oil first, test whether it can be used." You immediately fix the four pieces of cloth to the original reserved position, and I will test the ship immediately! ”

"King Shenxiao has an order, the spacecraft is ready for test flight!"

At the sound of the order, the craftsmen on standby immediately got busy.

"Set sail!" The sailors began to fix the freshly painted cinnabar cloth symbols.

Ye Jinyu rudely divided the boat into four sections, each of which was divided into a thick canvas charm; The design refers to the V-22 Osprey of the United States, and the upper end of the cloth charm is strongly tied and fixed to the top of the mast with hemp rope; The lower end is also tied with hemp rope and fixed to the hull skeleton by some pulley sets; When the boat needs to rise, the pulley set relaxes, just as the propeller goes up when the osprey takes off, so that the canvas runes are parallel to the hull and are used only as ascending symbols; When the boat lifts off, the pulley group tightens and pulls the lower end of the sail down, so that the sail is erect, so that it becomes a standard sail, which not only pulls the boat up, but also acts as a driving force to move forward.

While the sailmakers tied the canvas, the shipwrights retracted the front and rear anchor chains and pulled them to the deck, and the wooden stakes used to hold the hull on both sides were knocked open one by one, and the entire hull was separated from the fixtures.

The helpers carried a large number of buckets into the bilge, ballast water was essential to ensure that the center of gravity was under the ship; They are not only ballast, but also drinking water for the ship's crew.

Ye Jinyu was not idle, he took Li Chunfeng up and down the spacecraft, doing the final line inspection work before the spacecraft test flight. In fact, the circuit has been checked several times, and there is no problem, just wait to connect the circuit of the four canvas symbols.

"Your Highness, the sails are ready!"

"Your Highness, ballast water is ready!"

"Your Highness, the ship has detached."

Ye Jinyu was carefully flattening the four-squared copper core, then gluing it to the rune pins with adhesive tape, and then asking a skillful tailor to sew it onto the canvas with a needle and thread.

The news about the ship kept coming; Watching the tailor carefully knot the final thread, all the preparations are over.

Come to the command room on the fifth floor.

Here, a carpenter has created a replica of a console to which various switches are attached, each with a name.

After Ye Jinyu came up, he sat down on the captain's chair and took out an electric horn from under the chair: "Hey! Feed! Feed! The voice was very loud, startling Li Chunfeng, who was carefully studying around the console in front of him.

Without waiting for Li Chunfeng to trouble him, he took the horn and said to the craftsman on the railing outside the bridge: "Ring the alarm bell and let the unrelated personnel withdraw from the spaceship." ”

......The bell rang urgently, and the people who had no jobs on the ship were driven off the ship by the soldiers of the Forbidden Army, and then looked enviously at the colleagues who could get on the ship from a distance.

At this moment, Shi Sun Xin, the head of the Shenxiao Palace, ran to the control room panting, and as soon as he saw Ye Jinyu, he persuaded: "Your Highness, Fang Caichen heard that the craftsman said that His Highness wants to try this spaceship in person, but is it really something?" ”

Ye Jinyu nodded, and said in his heart Isn't this nonsense, this is the world's first spaceship, and it is the first spacecraft that he supervised and manufactured, how can he be without himself when conducting flight tests.

"Your Highness, a gentleman does not stand under a dangerous wall! And this ship test flight, should it be shown to His Majesty? Sun Xin had seen the scene of the flyboard falling with his own eyes, and he was not very confident about the spaceship built by Datang craftsmen; It's just that in front of everyone, it's not good to openly say that this spaceship is not safe, so he changed his method to persuade Ye Jinyu not to end up in person.

Dangerous walls or something, Ye Jinyu is not afraid, although he has not prepared a parachute, but there are several hanging charms in his pocket. In case of an accident, he also has mana, although it is not powerful, but it is no problem to control the suspension charm to fly down.

As for the emperor, he thought about it for a while, and still said: "This time it's not feasible to just test the sail talisman, this thing is the first time to fly in Datang, there is no case to follow before, if it succeeds, it's okay, the emperor looks at the light on his face; In case of failure, the entire Divine Man Workshop will have to lose face. Therefore, this test will not be called the emperor, and it will be called when the real test flight is held. ”

Saying that, he no longer paid attention to Sun Xin, and said to Li Chunfeng: "Senior Brother Li, you are more experienced in switch control, this time you came to assist me in controlling the spaceship." ”

Li Chunfeng couldn't wait, listened to Ye Jinyu's words, and nodded heavily.

After Ye Jinyu saw him nod, he got up from the captain's chair and shouted outside with an electric horn: "Everyone pay attention, start the test take-off now." Those of you who stand hold firm hold of the handrails, and those who sit sit well. ”

The electric horn sent the voice of the god man far away, and the indigenous staff on the ship couldn't help but look at the fifth floor where the command room was located when they listened to this voice from the sky, and they were waiting for further instructions from the god king.

And under the ship, more and more people gathered around, not only craftsmen and soldiers, but also their families; The news of the ascension of the spaceship of the Gods' Workshop is spreading rapidly, and outside the Gods' Workshop, many people have climbed onto the roofs, trees, and other walls, and they are quietly waiting for the miracle to come.

"Open the main gate and power it on!"

"Open the main gate and power it on!" Li Chunfeng repeated Ye Jinyu's words, and then pushed the empty open marked with the three words of master switch to the 'open' side. The light-emitting electrode next to the switch lit up.

"The mainsail is energized! Hang a gear! Ye Jinyu ordered again, and as soon as he finished speaking, he looked nervously at the canvas outside;

"Mainsail 1st gear!" This time it was operated by two workers, who had already practiced several times when installing the switch. Two people with four hands, one hand controlling a fan gear switch thing, twisted to the first gear.

A few pieces of canvas that were still hanging on the deck, as soon as the electricity was turned on, immediately soared into the sky like chicken blood, and collapsed straight. The whole hull shook as they tugged, and the hull creaked as if it were about to fall apart.

It's done! Charms can be used! Ye Jinyu was so excited that he almost shouted yes!

It's just that the boat shook a little and then didn't move, and no matter how hard the four pieces of canvas floated upward, it just didn't move.

It looks like the battery is not enough. Ye Jinyu forcibly suppressed the excitement in his heart and raised his voice and said:

"Second gear!"

"Second gear." All four hands were twisted into second gear almost simultaneously.

A stronger current acted on the rune sail, and the wooden hull of the spaceship made a more violent wood squeezing sound, Ye Jinyu was worried that the carrying capacity of the cloth rune was not enough and would not be able to pull the spaceship; And Sun Xin behind him clenched his fists with both hands, so nervous that he couldn't do it, for fear that if the broken ship fell apart, he would hit the street.

At this moment, the hull of the ship swung sideways, and it seemed that it had left the ground and was slowly rising.

The person sitting in the boat didn't feel it obviously, but the people outside the boat saw that the boat was indeed floating, although it was less than a foot above the ground, but it really flew. For a moment, the cheers of the craftsmen outside the ship were thunderous. When the voice reached the command room, Ye Jinyu was convinced that the ship was rising.

The ship flew up, and did not fall apart, and it seems that it was a success for the time being. Ye Jinyu's nervous mood was half relaxed, at least he hadn't done useless work for so long; It's just a pity that there is no altimeter, so there is no way to know exactly how high the ship is flying now.

"Third gear!" People are not so nervous, and Ye Jinyu's voice is much lighter.

"Third gear." The four hands flicked the switch again.

The scenery outside the ship descended at a relatively rapid pace, and more and more people in the city saw a huge wooden boat rising higher and higher, as if it was about to fly beyond the clouds.

Outside the Godman's Mansion, the national teacher held a bunch of ancient books, stared blankly at the wooden boat in the air that was getting smaller and smaller, and slapped his thigh fiercely: "Bad guy!" Scoundrel! ”
