After instructing Sun Xin to go back and find a storefront to hang up the signboard of the bookstore, Ye Jinyu talked to Li Chunfeng:

"Senior Brother Li, didn't the emperor let you stay in the Organ A Camp? How do you have the leisure to run behind the ass of the national teacher? ”

Since the last time he moved some Tianhuangshi seals back to modern times from here, Ye Jinyu has only returned to Hanzhong once, or at night, to ask for words; So it's not very clear what happened to those mechs.

"The crown prince is in an urgent situation in the north, and the people of the organ A remain in the Turkic court, and His Majesty has granted this matter; At present, there is no need to be poor and poor. Only the workshop is still in operation to create a new mechanism A person, and the person of the mechanism A has been finalized, in which the size of the craftsmen is clearer than the poor road, and there is no need for the poor road; Only the battery and wire craftsman needed by the first person can not solve the problem. ”

Li Chunfeng found Ye Jinyu to solve the battery needed for the new mecha.

"Okay, I'll make a note of it, and I'll send another batch over later." Ye Jinyu nodded and said, "How many batteries do you need there, and don't forget to ask the emperor to pay for the goods." ”

Sun Xin was still with Ye Jinyu and didn't leave, and when he heard about the payment, he hurriedly said: "Your Highness, a few days ago, an official in the palace sent dozens of catties of gold. ”

Li Chunfeng is more concerned about quantity: "The preparation workshop of the organ A has been expanded again and again by His Majesty, and today there are thousands of carpenters and blacksmiths; Thousands of pounds of wood and iron are consumed every day, and ten people are produced every day; After the craftsmen are cooked, the output will increase; Based on this calculation, ten batteries and several wires and runes are needed per day. ”

Batteries, wires, and runes produced in batches are the contents of Ye Jinyu's transaction with the emperor, and Li Chunfeng is right to find Ye Jinyu.

"There is also a matter of battery charging, which is also urgently needed to be solved by Shenxiao King!"

Battery charging has always been a big problem for the Tang people, after all, Datang does not have a generator, Ye Shenren often appears in Datang, and when the battery is out of power, he can take it to modern time and space to charge; But Ye Shenren is so busy, as soon as he comes to Datang less, the people here are Muggles. Fortunately, people with flexible brains came up with the idea of using the solar and wind turbines on the spacecraft to charge the battery. Temporarily fixed some of the issues.

But at the moment, this part is not easy to solve, because the ship was transferred to the palace by the emperor to act as a royal air pleasure ship, and the matter of charging had to be shelved; What's more, the number of batteries in Datang space-time is increasing, and the amount of power generated on a single spaceship is also a drop in the bucket.

Batteries and power generation equipment are the key problems that need to be solved in front of Ye Jinyu. The generator is a lot more troublesome, first of all, it can't be too big, it can't pass through the space-time gate; But it must have enough power to generate electricity, otherwise it will not be able to carry a few batteries. In addition, it is necessary to consider the fuel problem of power generation equipment after it arrives at Datang, whether it is coal power, oil power or gas power, all need to be considered; In fact, what Ye Jinyu wants to get most is hydropower, just find a river to build a dam for this thing.

Alas, the more I thought about it, the more I had a headache, I couldn't think of a clue at all, so I turned around and asked Lu Yuwei to find out if there was any suitable power generation equipment; If it doesn't work, find an expert, and do professional things with professional people.

A charging problem stumped Ye Shenren, as Ye Shenren's stall spread out in Datang time and space, there are more and more things that need to be bringed, there are still two spacecraft power equipment to be transported, and there are a bunch of battery orders here, in the long run, I just guard the space-time gate every day to move things, and I don't have to do anything else at all.

Ye Shenren couldn't help but think, why was the volume of the battery so big, he couldn't take a few at a time, if it could be like the spirit stone that activated the Spirit Gathering Array, it was small in size and light in weight; Just one small one can provide a huge amount of energy.

Hey, that's not right......

This thought turned from his head, and with a flash of inspiration, Ye Jinyu suddenly felt that he had discovered something; Batteries, spirit stones. Could it be that this spirit stone is also like a battery, which belongs to the carrier of stored energy, so it can pass through the space-time gate without hindrance. The more I think about it, the more I feel that this possibility is very high, the battery can't start the spirit gathering array, maybe it's just that the power is not enough, just like using a No. 5 battery with a three-phase motor that can't use 380 volt power electricity.

According to this algorithm, if the stone can be guided to release energy, it will still be a major key to solving the energy problem in the new century.

Of course, the world's energy problem, Ye Jinyu can only think about it, he doesn't have the strength or the capital to study the spirit stone; What's more, now he even has only one raw material, and he has used it.

It's just the reason why the spirit stone can pass through the time and space gate without hindrance, Ye Jinyu figured out, what is the mystery of the bag of beans that passed through the door with the spirit stone? Could it be that they are also carriers of energy? Or like the thousand-year-old ginseng on TV, eating one can increase your strength for a hundred years?

Seeing Ye Jinyu in a habitual daze, Li Chunfeng pulled him.

came back to his senses, Ye Jinyu said: "Don't worry about the battery, I'll get some when I go back; As for the charging equipment, well, I want to figure it out. ”

Li Chunfeng didn't say anything about the battery, but took the electronic magazine and handed it to Ye Jinyu and asked, "King Shenxiao, I don't know which sect and sect the talisman mentioned in this talisman book is, and why it is so sophisticated!" ”

Yes? Ye Jinyu was stunned for a moment, and said in his heart that this was not an electronic primer given by Zeng Ziguo's brother? How can you print runes? Hurriedly turned his head over to take a look.

The green substrate is densely packed with a lot of copper foil.

What is the rune, a standard circuit board, which is clearly marked below: PCB circuit board.

This is the simplest single panel, and the copper foil strokes are quite thick; Drawn at the forefront of the magazine for novices; However, compared to the Tang people who used a brush to paint, the copper foil two or three millimeters wide was indeed quite precise.

Ye Jinyu blurted out: "This is a circuit board, not a rune." ”

Li Chunfeng seemed to be very interested in the circuit board, and asked again: "Circuit board? What is it? He Sect and He Sect, why is it so similar to runes. ”

Ye Jinyu couldn't explain what the circuit board was, because he only knew it himself, and he really wanted to explain, and he didn't know where to start.

However, Li Chunfeng's words made him stunned for a moment, speaking of which, this rune is really a bit similar to a circuit board, for example, both can be driven by electricity, and their respective design goals can be activated through electrical energy. In this way, isn't the circuit board just a variant of runes?

I think when Ye Jinyu first learned talismans, he also considered a lot of talismans, what kind of wood and stone, and even asked about the iron plate! Of course, in the end, it was back on the paper, after all, it was the rune base that the Dao Sect had selected for thousands of years.

Just when Ye Jinyu thought that the best material for Fu Ji was paper, he didn't expect a circuit board to suddenly pop up!

What happens if you use a PCB board as a rune base and a copper foil circuit instead of a rune? This thought grew wildly in Ye Jinyu's mind like a weed.

Since he learned the runes, he has thought about how to use the runes in modern times, but modern society is a technological society, and he is a little afraid of being harmonized by the chatter of gods and gods in broad daylight;

If the PCB board can be made of runes and the copper foil can be made of runes, it must be the correct way to open rune technology in modern society!
