Yu Xier asked, "Who is Kishida Yinka?" You seem to have heard of him. ”

Lin Fei shook his head and said, "No, I just think this name is quite interesting." Lin Fei laughed dryly twice after speaking, and said, "There must be no problem in handing over Chiyo Mika to this Kishida Yinka." ”

Yu Xier was stunned for a moment and asked, "Why are you so sure?" You don't know him. ”

This Kishida Ginka was a well-known spy leader in Japan during the Lin Fei era, and the Rakuzendo he opened was a spy agency, and during the Sino-Japanese War, Kishida Ginka and his Rakuzendo provided the Japanese military with a lot of information about the Qing army. Since Kishida Yinxiang has a close relationship with the military, there must be no problem in handing over Chiyo Mika to him, so Lin Fei is so sure.

However, Lin Fei didn't say this reason, he just said lightly: "It's nothing, let's go find Miss Chiyo Mika now, tell her the news, and then prepare to send her back." ”

Yu Xier thought for a moment and asked, "She won't reveal our secrets, right?" ”

Lin Fei shook his head and said: "Don't worry, no, she doesn't understand technology, she doesn't know anything about what we have done on the island, the only thing she knows is that we have issued banknotes, and she knows that this matter is nothing." ”

Yu Xi'er nodded, and the two of them found Chiyo Mika together, Chiyo Mika was teaching the staff how to calculate accounts in the bank, and when they saw Lin Fei and Yu Xi'er coming together, they hurriedly got up to greet each other and asked, "Captain, Yu First Officer, why are you here?" ”

Lin Fei looked at the staff and said, "It's not convenient to talk here, let's find a convenient place." ”

Chiyo Mika turned to the staff and said, "You guys go back first, and we'll talk about it tomorrow." ”

All the staff went out one after another, and Chiyo Mika smiled: "Can you say it this time?" ”

Lin Fei nodded and said, "That's the case, Mei Xiang, we have found a very reliable Japanese businessman in Taiwan, who can send you back home safely." ”

Chiyo Mika's eyes lit up and she said excitedly, "Is it true?" Great, I can see my father and mother again! ”

Chiyo Mika's face was full of joy, but a strange feeling suddenly appeared in Lin Fei's heart, Chiyo Mika suddenly quieted down, looking at Lin Fei silently, Yu Xier didn't say a word, turned around and walked out, and gently closed the door.

The room was very quiet, neither of them spoke, Lin Fei laughed, and said, "Meixiang, you can go home, I can be regarded as fulfilling my promise." ”

Chiyo Mika smiled and said, "Lin Feijun is a very good person, I feel very happy that I can help you escape from the prisoner of war camp." ”

Lin Fei smiled: "Then please don't tell anyone about the things on this island, okay?" ”

Chiyo Mika nodded and said solemnly, "If anyone asks, I'll say that I've been held all the time and don't know anything." ”

Lin Fei smiled: "Then thank you, if it's okay, I'll leave first." After Lin Fei finished speaking, he pushed open the door and walked out, Chiyo Mika looked at Lin Fei's back and the closed door, tears actually burst out of her eyes, blurring her vision......

Lin Fei came to the door, Yu Xier sighed, and said: "After a long time, it should be a good day and a good time, even if there are thousands of styles, who to talk to." ”

Lin Fei said helplessly: "Lao Yu, don't drag the text, come with me, we are going to carry out a major upgrade of naval weapons." ”

Yu Xier hurriedly asked, "How can we upgrade?" ”

Lin Fei said: "The first step in upgrading is to have enough shells, our Nuwa ship has 6 120mm naval guns, and the stock of shells is running out, so we have to make shells." ”

Yu Xier thought for a while and said: "Cannonballs and bullets are much the same, now we can make bullets, and cannonballs can naturally be made." ”

Lin Fei said with a smile: "When I was making the cannonballs, I decided to transform the cannonballs well!" ”

Yu Xier said in surprise: "Transformation? How to transform? ”

Lin Fei smiled but did not answer, and took Yu Xier to the chemical production area, just in time to see several craftsmen disassembling a 120-mm naval gun shell and pouring the black powder in the warhead into a large wooden barrel filled with water.

Lin Fei pointed to the black powder in the warhead and said: "You must know those powders, they are all black powder, and the explosive power of this kind of thing is extremely low, so our newly made shells must no longer be filled with black powder as explosives." ”

Yu Xier nodded and said: "Yes, the explosive power of black powder is indeed lower, we should use nitroglycerin explosives better." ”

Lin Fei smiled: "What is nitroglycerin explosives? We're going to load even more powerful explosives! ”

Yu Xier was confused and said: "More powerful than nitroglycerin?" Could it be picric acid dynamite? ”

Lin Fei said with a smile: "Although the explosive power of picric acid is strong, it is very toxic and unsafe, so I plan to make trinitrotoluene as an explosive." ”

Yu Xier was stunned for a moment and asked, "Trinitrotoluene?" What is that? ”

Trinitrotoluene is the famous "TNT explosive" in Lin Fei's time, although this substance was accidentally discovered by scientists in 1862, but it has not been known until the beginning of the 20th century, replacing picric acid as a cannonball charge, so Yu Xier has not heard of this explosive.

Lin Fei said with a smile: "Trinitrotoluene is a powerful explosive, it is made of nitric acid and toluene, nitric acid can be made from saltpeter, as for toluene, I have found coal suitable for coking, and built a coking plant, and the process of coking has obtained a variety of chemical raw materials, including toluene." ”

As the two of them talked, they came to the coking factory area, and saw a huge coke oven standing in the middle, and various pipes were connected to the coke oven. Lin Fei pointed to the tubes and said, "Those tubes export all kinds of coking products, and go through a series of processes to get the toluene we need. ”

Yu Xier couldn't help but give a thumbs up when he looked at the tall coke oven, and said, "It's really good, we also have such advanced things." ”

Lin Fei laughed and said: "The melting point of trinitrotoluene is very low, we can melt the explosives before charging, and then pour them into the shells with a certain pressure, and the shells that come out of this way will be loaded with more explosives and the explosion power will be stronger!" ”

Yu Xier praised again and again, and Lin Fei then smiled: "It's not enough to have cannonballs, our cannonballs still have to be accurate, what do you say we use to make the cannonballs more accurate?" ”

Yu Xier said: "The error of the shell mainly comes from the shaking of the hull, as soon as the hull shakes, the direction of the gun's gun will change, so it is difficult to aim, although the experienced gunner can control the timing of the gun, as far as possible with the wave movement of the ship to the moment of the gun, to minimize the impact of the waves, but the error is still very large." ”

"If you want to reduce the impact of hull shaking on shooting, you must increase the stability of the hull, but if you want to increase the stability of the hull, you must transform the hull, and with our current industrial strength, it seems that the hull cannot be transformed."

Lin Fei nodded and said, "Yes, it is true that the hull of the ship cannot be modified now, and the newly built warship is not reliable, so I thought of another thing." ”

Yu Xier hurriedly asked, "What do you think of?" ”

Lin Fei didn't answer directly, but said: "You just said that the error of the shell mainly comes from the shaking of the hull, only half of it is right, and there is another major source of error, that is, the measurement distance, if the measurement distance is not accurate enough, the shooting will also have a large error." ”

Yu Xier shook his head helplessly and said, "I don't know much about measuring distances. ”

Lin Fei said with a smile: "I looked at the Nuwa ship, there is no rangefinder on it, so the estimation of the distance can only rely on the experience and feeling of the shooter, the experience and feeling are very unreliable, so the shooting error of the naval gun is extremely large, if we have one thing, we can accurately measure the distance, then the shooting error will be greatly reduced." ”

Yu Xier's eyes lit up and said, "Rangefinder? I heard about this stuff when I was in England! Are we going to make our own too? ”

Lin Fei nodded and said, "Not bad! While the two were talking, they had already walked outside a workshop, and light smoke was rising from time to time in the workshop, Lin Fei pointed to the door of the workshop with his hand and said, "This is where the rangefinder is produced." ”

After Lin Fei finished speaking, he walked in, Yu Xier followed behind Lin Fei, as soon as he entered the door, he felt a heat wave rushing to his face, only to see a one-person kiln in the middle of the workshop, the kiln was burning with red flames, two strong men were pulling the bellows on the side, bringing up the sound of "whirring" wind, the wind blew the flames more and more, and an old man with gray hair was standing in front of the fire, looking at the fire intently.

Yu Xier was just about to speak, Lin Fei waved his hand lightly, signaling him not to speak, but at this moment, he only heard the old man break off and shouted: "Open the kiln!" ”

When the two strong men who pulled the bellows heard this, they immediately stood up from the edge of the bellows, pulled a handle on the kiln body, only to hear the sound of "click" coming from the kiln body, and a trap door on the kiln body opened, and a snow-white mucus flowed out from it, and the mucus flowed into a ceramic crucible, and gradually condensed into a crystal clear piece.

The old man carefully picked up the crystal clear thing, looked at it again and again, and then put it back into the crucible, and said to a strong man, "Put it in the grinding room." ”

The strong man picked up the piece of stuff and left, and Yu Xier whispered to Lin Fei on the side, "Is that piece of glass a piece of glass?" I think it's a lot like glass. ”

Lin Fei nodded and said, "Yes, it's glass!" ”

At this moment, the old man turned around and walked towards Lin Fei, and laughed loudly: "City Lord, why are you here?" The glass you want is grinding, so you can't go wrong! ”

Lin Fei turned back to Yu Xier and smiled: "Let me introduce you, this old gentleman is a famous glass maker, Wang Zhengbin, Mr. Wang." ”
