Traveling through the Legend of the Condor Heroes: I, Yang Kang, Have Nine Yang

Chapter 265 Shipbuilding
After parting with Guo Jing, Cheng Yaojia was very sad, Yang Kang, as her senior brother, had no choice but to comfort Cheng Yaojia, and see each other sooner or later.

Afterwards, Yang Kang asked Cheng Yaojia about his plans, and after Cheng Yaojia heard about Yang Kang's career, he also wanted to help.

Yang Kang naturally readily agreed to this, and just asked Cheng Yaojia to act as Mu Nianci's assistant. Both of them can use the "Jade Girl Sword Technique", and Cheng Yaojia can also use the "Quanzhen Sword Technique".

In this way, the two daughters can combine their swords and use the "Jade Girl Suxin Sword". At that time, the combined strength of the two women can resist even the super-class masters in the world.

But this also reminded Yang Kang of Li Mochou, so he asked: "Yao Jia, do you still remember Li Mochou?"

After being reminded by Yang Kang, Cheng Yaojia seemed to think of something, and replied: "Brother, when you say that, I think of sister Li Mochou, why did you abandon her at that time?"

When Yang Kang heard this, he blamed himself for a while, but he still said the truth: "At that time, I saw her almost hurt you. She looked crazy. I...I was afraid that she would hurt other friends and relatives around me in the future."

When Cheng Yaojia heard the words, he couldn't help feeling a burst of joy and a burst of regret.

If she had heard this before meeting Guo Jing, she must have been filled with honey, and even had fantasies, but after meeting Guo Jing, that unrealistic fantasy was also abandoned.

Even so, she was extremely happy, after all, Yang Kang really treated her as a relative.

However, thinking in her mind, she still said: "But you don't know how much you make sister Li Mochou sad by doing this."

"Hey, do you have any news about her later?" Yang Kang asked helplessly.

Cheng Yaojia shook her head, "I only know that after staying in Zhongnan Mountain for a while, she went to the rivers and lakes to look for you."

Hearing this, Yang Kang frowned tightly.

Li Mochou went to the rivers and lakes to look for him, but there was never any disturbance in the rivers and lakes. Just like in the original book, she became a Chilian fairy. It seems that Li Mochou must have listened to Yang Kang's words.

It seems that he still did not trust Li Mochou at the beginning, which made him blame himself even more, but at this time Li Mochou had been unable to find him in the world, and he had no way to make up for it.

If one day I see Li Mochou, I can only apologize and blame myself.

After that, Yang Kang took Cheng Yaojia and rushed to Jiaxing in the east.

After Cheng Yaojia, Huang Rong, and Mu Nianci met again, their relationship was unexpectedly good, especially because they all knew that Yang Kang only regarded Cheng Yaojia as his younger sister, and had no other feelings between men and women, which made them not only incapable of Jealous of Cheng Yaojia, but will think about how to make friends.

In this regard, Mu Nianci is much luckier. As soon as Cheng Yaojia came, Yang Kang let her be Mu Nianci's deputy, and the two also discovered how similar their martial arts skills are. Can have a set of combined fencing method "Jade Girl Suxin Sword".

And because of the requirements of "Jade Girl Suxinjian" cultivation, the relationship between the two girls is naturally much better.

But these are not what Yang Kang cares about. After Yang Kang returned, he focused on developing the shipbuilding industry, which is related to the foundation of his future aspirations to the world.

In fact, during the Southern Song Dynasty, China's shipbuilding technology was very developed.

The capital city of the Southern Song Dynasty was located in the south of the Yangtze River, and the waterway transportation was very convenient, so the shipbuilding industry was very prosperous. Quanzhou, Guangzhou and other places were the shipbuilding centers at that time, and they were able to manufacture large-scale long-distance ships, representing the most advanced shipbuilding technology in the world at that time.

At the same time, the shipbuilding technology of the Southern Song Dynasty has many characteristics, such as the adoption of various advanced construction technologies and ship designs, especially great progress in the design of materials, ship shapes and masts.

In addition, ship equipment and instruments have also been improved.

The structural design of various parts of the sea-going ships of the Song Dynasty is also very reasonable, such as the bow, stern, keel, etc., are all carefully designed to improve the stability and navigation ability of the ship.

And Yang Kang's understanding of future shipbuilding is not very good. After all, he is not a god-man, and he can still Baidu after traveling to ancient times, but he still has some understanding of sailing technology in the Western Great Navigation Period.

In addition, some other subtle technologies can also be improved to make the times a little bit better, but that's all.

He went to the shipyard he had already acquired, took out many sheets of paper, and tried to draw some sails from the period of great voyage that he remembered.

However, when he was drawing, he suddenly looked at the paper with a little brownish green in the yellow, and couldn't help but recall the white and clean printing paper in his previous life. Looking at the writing brush in his hand, he couldn't help but think of the very convenient paper in his previous life. gel pen.

He misses these things very much, and he can't help feeling strong, and they are extremely convenient, and most importantly, they will greatly improve the efficiency of his writing, work, administration, and study.

Naturally, the method of bleaching paper is to use bleaching agent. The most convenient way is to use chlorine powder. The main materials are sodium chloride, water and diluted calcium hydroxide. These are not complicated. The combination of the first two is seawater, which is slaked lime.

As for the gel pen, he couldn't think of any production method that could reach the sky in one step, so he had to choose the quill pen as the second best.

A quill is a traditional writing tool consisting of a quill and a barrel.

When making, the goose feather needs to be processed several times to remove the hair core and feather shaft, and trim it into an appropriate shape as needed; then, insert the goose feather into one end of the pen barrel and fix it with glue; finally, adjust the shape and shape of the pen tip as needed Hardness to suit different writing needs.

It can be predicted that the emergence of these two things will greatly improve the efficiency of writing and work in ancient China, and will also bring broader development space and possibilities.

In addition, after these two things were produced on a large scale, the clean, white and spotless white paper soon outperformed those rice papers, which caused many nearby scholars and talents to compete to buy them, and they were proud of them. It added an unexpected harvest to Yang Kang.

Back to the topic, Yang Kang began to draw the blueprint of a new type of ship by relying on the two newly developed tools—of course, mainly on the sails, of which there are mainly two kinds of sails.

The first type is the rectangular sail. It should be noted that the most common type of sail in the period of great navigation is the rectangular sail. This kind of sail is supported by a vertical mainmast and supported by a series of horizontal transoms.Their shape resembles a rectangle, hence the name.

Rectangular sails are great for sailing in tailwind or offwind conditions, but are less efficient against a headwind.

The second is the jib, another common type of sail, which is supported by a sloping mainmast supported by one or more diagonal lines.Their shape resembles a triangle, hence the name.

Spinnakers are great for sailing in headwind conditions because they make better use of the wind.

As for sail materials, sails are mainly made of canvas, usually using hemp, flax, or cotton fibers, which are very similar to those used in papermaking, and are not difficult to obtain.

Of course, these are civilian ships, and real military ships need to be built after the occupation of Yizhou Island. After all, I can't develop the navy in front of the Southern Song court.
