"Behind the sailor cabin is the arsenal, and underneath is the bottom cabin, mainly cargo. Let's take you to see the bottom cabin of the flagship."

The bottom cabin was very empty, Zhang San explained: "This time we took the north road."

"Chinese ironware can be exchanged for the same weight of fine copper in Japan. The copper material is heavy, so the bottom warehouse looks very empty."

Open a cabin and reveal the copper ingot below: "Here is a thousand materials."

Su You is more interested in the cabin structure: "Why are there a row of rivets on these two sides?"

Zhang San said: "This is a new design of Hangzhou dock. There are stalks outside the cabin. It is located on the side of the boat. Even if it is empty, it is underwater and cannot be seen on the water."

"With it, it will be more resistant to waves when sailing, and it will reduce shaking when firing, making it more stable."

Su You understood that this is the keel reduction.

After checking the storage in the boat, Zhang San pointed to a cabin and introduced: "The hams here are all pigs' right front hooves."

Su You asked, "Why? Can't you hind your legs?"

Zhang San explained: "The pig's front hooves are tenderer than the hind hooves, which is more delicious. Moreover, when pigs sleep, they usually lie on their left and their right hooves are in the air, so the right front hooves are better than the left front hooves."

Su You laughed: "I'm really picky!"

Zhang San also smiled: "How can we not picky about the people brought by our young master? Isn't that humiliating the family style?"

The two of them laughed wildly again. After laughing, Zhang San pointed to a series of cabins: "Young Master, look, there is also our unique Hangzhou-type device here - a water cabinet."

"The water cabinet is wrapped in copper skin and sealed, which can provide fresh water to crew members on weekdays, and can also adjust the weight of the bottom cabin."

"With it, the Hangzhou type can run farther than the other sea boats and take longer offshore."

Su You nodded: "The progress is really considerable."

Zhang San smiled like a fox who stole a chicken: "The most feared thing about Fanbo is scurvy, but we don't have this problem. There are canned fruits, dried fruits, tea powder, and enough fresh water to produce bean sprouts... Life is better than that of the sailors on Fanbobo," he said.

After seeing the bottom cabin, the two of them turned around and suddenly a furry thing ran out and meowed with their tails standing upside down.

It turned out to be a beautiful little cat with long fur, a bit like a Persian cat from later generations, but its fur is brown and yellow.

Zhang San picked it up: "It is called a slut, and it is a filial piety man from a foreign merchant selling lapis lazuli. He is said to be a Ghazni species, the favorite of sailors on board, and a good catching mouse."

After saying that, he squatted down and picked up the breast lion. The breast lion lazily collapsed on Zhang San's arm like an old man, and looked at Su You curiously.

Su You stretched out his finger and teased the lion: "I didn't expect that there was this on the boat. Nowadays, people and the palace love to raise cats. As soon as I came to Hangzhou, I solved a case related to cats."

Zhang San smiled: "That's the designated one is a precious cat."

Su You shook his head: "There is a little man named Sun San in the city of Bianjing. He takes cooked meat home every day and says that there is a precious cat at home, all red, called the dried red species."

"Later, it was spread to ten and ten, and everyone knew it."

"One day, the cat suddenly broke the rope and ran out. Sure enough, the dry red and dark color, the tail feet and hair were all there, and the people who saw it were all envious."

"His wife was hurriedly carried back. After Sun San returned home, he learned about this and beat his wife up."

"The story was introduced to the palace. After Wang Zhongzheng found out, he spent 300 guan to buy it. He was so happy that he prepared to tame the stickers and then send them to the palace."

"As a result, the hair color became lighter and lighter. After half a month, it became a white cat. When I visited Sun again, it was gone. It turned out that this cat was dyed!"

Zhang San also found it funny: "Hahaha... Three hundred guan is not a small amount, but cheating money on Taiwei Wang is also considered a great skill! Did you catch it later?"

Su You smiled and said, "They are so dying. As soon as I came to Hangzhou, I heard that a family had a cat named Dried Red. It's rare to see it on weekdays..."

Zhang San laughed so much that his breast lion couldn't hold him: "I don't even bother to change the color? Hahaha..."

Su You said: "After arresting, I asked, the person had already made arrangements: I had sold one in Hebei to Mr. Wen, and then the one in Tokyo was sold to Mr. Wang, and the one in Hangzhou was sold to Mr. Qian. Next, I was going to take a foreign ship and go out to sea to deceive the foreign people!"

Zhang San was so happy: "Then these two male and female mothers are stupid. The money of the foreigners is easy to make money without cheating!"

Back on the deck, Su You looked at the crossbows on both sides: "Is this thing still in use?"

Zhang San said: "Pili Cannon is very powerful in dealing with water villages and ports. However, when dealing with the current hundreds of small boats, some people use ox knifes to kill chickens. The knives are too powerful, and often shells hit the hull, and they have not had time to explode."

Su You couldn't laugh or cry: "So that's it."

Zhang San said: "Now, the best thing to use is a spring delay fuse, and a hook needle is added to the tail of the porcelain bullet to attack the enemy's sails."

"After the porcelain bullet is filled with hot turbulence and explodes on the sails, the rest is simple."

Speaking of this, Zhang San remembered something: "It was a few brass shell shells filled with half of the charge, and the remaining half was filled into iron sand. This kind of recharged ammunition was very effective in Qing Shaowang's deck."

Su You held his forehead with his hands: "This kind of thing is too simple. This is a generation of mother-child guns, and the gun barrels don't even need to be rifled. When the industrial base is up, you will have to get this done for you in minutes."

The two of them came to the captain's room with a chat and a laugh. Several merchant-like people were already waiting here, nodding and bowing with a charming smile.

Zhang San then realized: "I was happy when I saw the young master and forgot to order the unloading of the goods. Go quickly."

Su You smiled and said, "Today I will handle the special matters and tell the people from the Maritime Bureau that I am here to make them more skillful."

Several merchants bowed and thanked, and went there happily.

Su You sat down and saw a dictionary on the captain's desk. He asked, "The four-corner number is still useful?"

Zhang San bowed his hands and said happily: "This thing is a magic weapon, used to command the fleet, it is like a divine help!"

The method of searching characters for four-corner numbers is a common method of character checking characters in later generations, and it is intuitive and convenient to obtain codes.

In the four-corner number search method, basic strokes such as horizontal, vertical, horizontal, and horizontal strokes are retained, and they are called single strokes. At the same time, some units of character formation called complex strokes are added. They are a combination of multiple basic strokes, such as "X", "Ten", "Eight", "People" and "Man" that cross two strokes.

Among the four-corner numbers, a total of ten are defined by single and duplicate numbers, represented by ten numbers: zero to nine.

When searching the characters, take the single stroke or a duplicate stroke shape at the upper left corner, upper right corner, lower left corner, and lower right corner of the Chinese character. There are four codes in total, and a Chinese character can be expressed with four numbers.

There are too many characters in the Song Dynasty, and the four-corner numbers can only be marked with 10,000, but they are enough for maritime use.

If you really want to meet the needs of the Bachelor's College, you may also need to add "with pen" in addition to the four corners to meet the needs.

After Chinese characters are changed to numbers, they can be easily converted into flags and lanterns. With the help of a telescope, communication between ships can be completed.

This will get rid of the simple and rough command system, allowing the fleet to change into more complex formations and achieve more precise cooperation.

The improvement of water combat power can be said to be a double-effect device.

Nowadays, Suyou no longer has to do everything himself and provide an idea, so there is naturally someone to do it below.

But this dictionary was really not made by him by his subordinates. He flipped through the big book: "It was made by Qian Family Bookstore in Hangzhou?"

Zhang San smiled: "This is the big deal of Marquis Qian. The Qian family has been in a century of cultural education and education, and has a very profound foundation."

After Qian Chu accepted the land, his descendants established themselves with culture and education, and they were well-deserved as the first family in Liangzhe.

Not to mention now, even after a thousand years, the Qian family in Zhejiang is still very famous.

The Qian family now has a super huge library, and the administrator is Qian He, the descendant of Qian's family. Su You are also making plans for this library.

Today, there are many aristocratic families in the Song Dynasty, mainly concentrated in Fujian, Liangzhe, and Shu, which had not been war-torn, such as the Wen Family Bookstore in Berlin, Qianzhou, Baidu Wanjuan Building in Putian, Fuzhou, Bogu Hall in Tian Family in Jiangling, and Chengsheren Library in Shu, all of which are collected by more than ten thousand volumes.

The Qian family’s library is called Jielou, and there is also a plaque written by Su Dongpo himself on it - Qian’s library.

Compared with these families, Su You's Kezhentang can only be regarded as a child.

The four-corner number is made by money and used in Zhijingnan's spare time.
