After showing the capacitors, Guo Kang showed them various coils, metal sheets and other devices.

"In addition to making these finished products, the materials themselves will also be a major research direction in the future." Guo Kang reminded them: "Do you know why I have been short of money before, and even the Patriarch's funding is not enough? ”

"These devices are expensive?" A monk asked.

"Yes." Guo Kang nodded: "For example, this thing." ”

He picked up a coil, and the monks found that it did not have cotton threads sandwiched between copper wires, as in the other coils; Moreover, this coil seems to have more than one layer, densely wrapped and very thick.

"This is the densest coil we can do so far." Guo Kang said: "We need to ensure that the copper wires do not touch each other, otherwise the electricity will not pass through this circle of copper wires, but will flow directly from the contact place." Before, the cotton thread soaked in oil was sandwiched in the middle to prevent the two sides from touching; Between the two layers of copper wire, a cotton cloth brushed with mineral oil or asphalt should also be padded. In this way, the volume and weight will increase. ”

"The method I came up with before was to paint it like this." He pointed to the black shell on the surface of the copper wire: "Just leave a little gap between the two wires." Wrap it around for a second time and wait for the paint to dry to form a non-conductive hard shell. This can save a lot of space and weight compared to the previous one. ”

"But we don't have this kind of thing, only the Ming Dynasty and the Javanese Yuan side have it - for this point, I tried to use it, or I asked Sun 100,000 to buy it at a high price."

"When we make it in large quantities, we can only use shellac instead." He picked up another one with a purple shell: "But shellac is not a cheap thing, this thing is made in India, and it has to be imported as well." ”

"And then, this zinc sheet — just for the battery." He picked up a piece of metal: "We can only make alloys here, and the elemental zinc can only be produced in India and the Ming Dynasty." It also has to be imported. ”

"And this." He pulled out a porcelain cylinder: "Compared to the pottery on our side, this kind of dense and non-absorbent porcelain is actually more suitable." But this also has to be imported. ”

"Wait. Can't we even make porcelain? Tuohuan asked.

"The heart of the porcelain is the high-temperature kiln. It was a huge thing and required the combined efforts of many skilled craftsmen. Guo Kang said: "Most of our craftsmen left the Central Plains in a scattered manner, and the large-scale teams are mainly military and water conservancy, which is not very good. ”

"You see, products such as papermaking and gunpowder have long been spread with the craftsmen who traveled west, but now in the whole world, only the Ming Dynasty and Javanese Yuan have the ability to make porcelain, and even the yen is barely very strong."

"Silk has spread because of the outflow of silkworm seeds. But porcelain is really not good. For example, he said: "During the Yuan Dynasty, the Portuguese obtained the process of kaolin and porcelain firing after several trips, but after returning to China, they tried again and failed. ”

"This thing is, send you raw materials, give you instructions, teach you to burn, you can't burn it." He shook his head repeatedly: "I know this sounds, it may be strange, but the reality is that. If you want to make real porcelain in Europe, you have to wait hundreds of years. ”

"That's really terrible." Tuhuan understood what he meant: "Hey, we have lost too many skills. Now I don't feel like I'm good at anything other than farming and fighting. ”

"It's about buying everything, but what about when you need to make a lot of it in the future?" He said worriedly: "The war over there will not stop, and it may be out of stock at any time." We're still going to have to figure out how to do it ourselves. ”

"As for batteries, I have an alternative at the moment." "I tried to make batteries from lead and sulfuric acid. Lead is used as one pole, and Hongdan is processed to make the other pole. This may be better, but it's also more difficult. ”

"There's a way." Tuhuan is relieved: "I think this idea is good." We Romans are familiar with lead, which belongs to promoting strengths and avoiding weaknesses. ”

Several of the priests were local experts in cultivating crops, and some were originally village craftsmen. They are happy to accept these jobs.

After a few discussions, it was quickly decided that more efforts should be made in this regard, and strive for an early breakthrough to solve the problem of key technologies being stuck by the eastern powers.

After discussing this, Guo Kang led them out of the chapel.

"We're going to the Workshop next." "There is nothing special about an ordinary workshop," he said, "but there is a workshop in the distance that produces all kinds of materials and utensils, and requires the use of various chemical ...... Oh, it's the alchemy process. ”

"I believe that proper study of alchemy techniques will also play a great role in understanding the world and the 'Logos' behind all things. It is a pity that many alchemists are now obsessed with ancient pagan superstitions, but they are not interested in the really important work of summarizing laws and theoretical analysis. ”

"You are all devout people who serve our Heavenly Father, and I am sure it will be clear to you what we really need to do." He took the opportunity to encourage: "Hopefully we can find something out of this, or at least support other research." ”

"In addition, there are a lot of dangerous substances over there, so you have to be cautious when visiting and researching."

The priests listened to him and said that they understood that they would not be fooling around like ordinary alchemists.

Guo Kang nodded with satisfaction and led them in another direction.

On the way, the priests noticed that not far from the chapel, there was another building. At the top of it also stands a huge bronze Heavenly Brother. However, behind this heavenly brother, it is not a traditional Greek cross, but a Ross cross with three horizontal frames. If you look closely, there is a slide rail behind Brother Tian, and the rope on your hand is also movable and can move up and down.

Now, Brother Tian was lowered a little and hung a little below the main cross arm. Since the arms are also stretched flat, it is equivalent to four horizontal lines appearing at the same time, which is different.

"What's that?" Brother Dmitry thought it was strange, but when he thought about it, he had seen a lot of things beyond his imagination today, and it was clear that he still had a lot of theological knowledge that he did not know. So, he humbly asked.

"Oh, that's the cafeteria." Guo Kang said: "The building, as well as the bronze sculpture on it, was not directly funded, but jointly funded by people from several quarters. The Ross church came out of the big picture, so it was done like this. ”

"The cafeteria also has a special function, but it is very immature. I was going to talk about it later, but since you're interested, let's stop by and have a look. ”

As he spoke, he led the crowd over.

Walking to the front of the building, everyone found that on the base of the statue, a circle of nameplates was made in Latin. IT READS: "GRATIOSVS", "GENEROSVS", "GLORIOSVS", "GAVISVS", "GRANDIS".

"What is this?" Tuohuan didn't know Latin and asked.

"They are: the gracious, the noble, the glorious, the glad, and the great." Guo Kang replied: "At that time, when the statue was customized, an Italian lady also paid a lot of money. These are all eulogies she selected, engraved here as a memorial to her dedication to her brother. ”

"It's also one of the core parts of the equipment, and I'll show you. This part—" He waved his hand and introduced: "I think these words start with 'G', so they are habitually referred to as '5G Heavenly Brother'." ”
