In fact, as long as you are an experienced captain, you have a certain understanding of the trade winds and ocean currents. If you are a person in the future, even if you don't go to sea, you can still understand the sea through a series of sailing games. One of the most famous games is probably "Age of Discovery". As long as you are friends who have played the game, I believe that you have a very deep experience of both tailwinds and headwinds. From Manila to Quanzhou, the tailwind only takes a moment. The headwind will take a long time.

The use of trade winds combined with ocean currents can greatly save time in the ocean, thereby reducing the possibility of scurvy. For example, the best time to travel from Quanzhou to Manila is summer. The best time to travel to and from this is autumn. If you miss these seasons, the time spent on driving against the wind or the current, will greatly increase the cost.

The best example of a voyage using trade winds combined with ocean currents is the Manila galleon (also known as a Chinese ship by the Mexican locals because the cargo carried is mainly from China). The galleon sails north from Manila in June every year by the southwest monsoon, to the waters of 45°~42°N, along the "Kuroshio" in the North Pacific Ocean, and finally arrives at Acapulco, a large city on the west coast of Mexico, with a journey of more than 10,000 nautical miles and a duration of about 6 months (the return journey is a direct voyage along the ocean current, which lasts about 3 months). Without the influence of trade winds and ocean currents, it would not have been possible to cross such a vast Pacific Ocean.

In the same way, ships from Europe also used the trade winds to set sail from Europe to East Asia. If returning to Europe from East Asia, the opposite time is chosen. Sailing along the West Seas of Africa is undoubtedly the most painful for sailing ships traveling between East Asia and Europe. Because, the east and west coasts of Africa happen to be a mix of trade winds, and the trade winds are not very stable. If there is a headwind, the time will be greatly increased.

Of course, for the current Fushan Water Army, the impact of trade winds, monsoons, ocean currents, and tides is not very large. The journey from Jiangnan to Qingdao, that is, hundreds of nautical miles, is really too short. However, be prepared, and if you want to sail far in the future, you must choose the right season. As for the tides, they mainly have an impact on landing operations, and Zhang Zhun did not explain this in detail for the time being.

As mentioned earlier, scurvy, the third part of the supplementary content in "Basic Knowledge of Navigation", the first article, is about the prevention and treatment of scurvy. Words such as lemon and citrus appear frequently.

In the history of human voyages, scurvy was definitely a deadly roadblock. It was not until the eighteenth century that this obstacle was completely resolved. At the beginning, in order to solve this strange disease, I don't know how many doctors invested in it, and a lot of manpower and material resources were consumed, but it was still ineffective. Eventually, a captain named Cook discovered that lemon juice was effective in preventing scurvy. At this point, scurvy was a complete farewell to the sea.

Now, Captain Cook has not yet been born, and Zhang Zhun naturally wants to steal his achievements. Scurvy is ultimately due to a lack of vitamin C. To prevent scurvy, vitamin C supplementation is sufficient. The easiest way is to juice lemons or citrus, save them, and drink them every day. In order to prevent scurvy, Captain Cook forced the crew to drink lemon juice every day, and if the crew refused to drink it, they would be flogged or other severe punishments.

In fact, there were already people in the Ming Dynasty who knew how to prevent and treat the occurrence of scurvy. This person is Gonggong Zheng, Zheng He. When he made seven voyages to the West, he used soybeans to beat bean sprouts on the ship, so that the sailors could eat them regularly, and successfully prevented the occurrence of scurvy. During his second voyage to the West, none of the crew members died of scurvy. However, this technology has not been promoted. At that time, people did not accurately realize that bean sprouts could prevent scurvy.

Poor Columbus, and Magellan, were tortured to death by scurvy every time they sailed. Even ships from the Western Ocean are now plagued by scurvy. Before scurvy could not be prevented on a large scale, there would not be many ships and personnel from the Western powers that arrived in East Asia. During the Opium War, a large part of the reason why the Anglo-French army was so strong was that the problem of scurvy was solved, and a large number of troops could be transported by long voyages.

The thick book "Basic Knowledge of Navigation" involves all aspects of navigation, and of course Zhang Zhun cannot teach it in one day. That night, Zhang Zhun went back. The next day came again to continue imparting the relevant knowledge. This continued for several days, until the escort team held a skill competition, and Zhang Zhun stopped for a day. Subsequently, the lectures continued.

In the blink of an eye, it was August 14.

Because tomorrow is the Mid-Autumn Festival, the most solemn festival after the riots in Fushan City, Zhang Zhun therefore ordered a two-day holiday. Except for the necessary guards, everyone else can take it easy. Of course, the people in the Intelligence Division are not easy. If they are relaxed, they are highly likely to trigger fatal consequences. In fact, there are still 100 people in the escort team who are in a state of combat readiness and can cope with any unexpected situation.

At noon that day, Zhang Zhun was eating in the barracks of the navy. The officer on duty in the navy is Zhou Zhengyu, he is a very self-motivated person, and when he eats, he also constantly learns about navigation from Zhang Zhun. For such a studious subordinate, Zhang Zhun naturally knows everything, says everything, and teaches everything.

While talking, there was a sudden sound of horses' hooves, and when I looked up, it turned out to be Ma Yi's arrival.

Ma Yi came to Zhang Zhun and reported: "My lord, Lin Renjie is here. ”

Zhang Zhun said lightly: "He should also come." ”

Shu Bulu made such a big move, and the various systems of the imperial court in Shandong must have some reactions, right?

After eating, Zhang Zhun rode back to Fushan City. Entering the Qianhu Official Hall, I saw Lin Renjie. The old man didn't know how to do it, he seemed to be a lot haggard again, and when he saw Zhang Zhun, he also looked a little listless. In fact, the old man's heart is not bad, and he can be regarded as a good person, but their respective status and position are there, and it is also a relatively insurmountable gap.

Zhang Zhun asked with concern: "Lord Lin, have you been a little sad lately?" ”

Lin Renjie only smiled bitterly.

What's a little upset? It's very bad!

Zhang Zhun took thousands of people and slaughtered Jimo County, frightening the officials of Aoshanwei and fleeing to Dengzhou Mansion one after another, and Lin Renjie was naturally among them. Although he has some friendship with Zhang Zhun, it's just that in the chaotic battle, what can such a friendship do? may have been killed by Zhang Zhun's subordinates before he saw Zhang Zhun's face. Zhang Zhun's subordinates did not have the slightest good impression of the officers of the guard. Falling into their hands can only be a dead end.

originally thought that after Zhang Zhun tossed, they could come back to Aoshanwei. Unexpectedly, Shu Bulu later landed and tossed and burned Laiyang County. A large number of refugees have flocked to Dengzhou City. Originally, after Dengzhou City was ruined by Kong Youde, it was already lifeless and dying. Now, with so many people suddenly pouring in, you can imagine how chaotic the situation inside will be. He is a small deputy Qianhu, and he is still a figure in Aoshanwei, but when he arrives in Dengzhou City, he is not even as good as a dog!

No, I've only lived in Dengzhou City for two days, and I've already been robbed three times by the rebels. Even his little daughter-in-law was almost robbed by the rioters. I heard that there were people from the Wenxiang Sect who were doing trouble in the city, and the prefect Zeng Hualong ordered the bombing and arrest many people. One of his children, accidentally, was caught and ransomed for a few hundred taels of silver. This child had just been ransomed, and another child had been captured. If you can't do it, continue to take money to ransom people. The result was a few hundred taels of silver.

Later, Lin Renjie realized that this was deliberately slaughtered by officials at all levels in Dengzhou Prefecture. The Dengzhou government does not arrest the chaotic people, the poor, or even the people who smell the incense, but specifically arrests those who are rich, and then takes the opportunity to extort and relentlessly fill their pockets. Pity them, they are under the roof, they have to bow their heads, so they have to obediently admit punishment. A small deputy thousand households, no soldiers and no power, what can you do? Even Zhao Yinying, the commander of Wei, came to Dengzhou Mansion and was treated the same as his grandson.

Alas, in short, it is difficult to explain. Lin Renjie swore that he would never go to the sad place of Dengzhou Mansion in the future. It's like the Cave of Hades, and all of them are good at slaughtering people. However, the worst is yet to come. He didn't stay long in Dengzhou Mansion before he was found by Zhao Yinying. Zhao Yinying asked Lin Renjie to come to Jimo County and told Zhang Zhun that they were willing to negotiate.

Zhang Zhun didn't expect Lin Renjie to have such an experience, so he had to sympathize. I have long heard that officials at all levels in the Ming Dynasty are all good at making money, and this is indeed the case. A subordinate thousand households have all been made like this, and it is conceivable that other powerless people are powerless. He said with a smile: "Lord Lin, otherwise, you will move to our Fushan House." ”

Lin Renjie had a bad time in Dengzhou Mansion, but he didn't mean to come to Fushan. Fushan City is still a thief, is he willing to become a member of the thief? Even if he is successfully appeased, maybe one day the court will change his hexagram, and he will still be the identity of a thief. One day is a thief, and a lifetime is a thief, unless it is a successful theft. He shook his head and smiled bitterly, and said obscurely, "Thank you for your kindness." ”

Zhang Zhun returned to the topic and said with a smile: "So, Lord Lin, did you bring me good news?" ”

Lin Renjie remembered his business, and said with a smile: "Congratulations, congratulations." ”

It turned out that Zhao Yinying was finally willing to relent, and was willing to appoint Zhang Zhun as the thousand households of Fushan. The past is not to blame. In other words, it's a formal appeasement. However, there is a precondition that Zhang Zhun cleans up the tartars of Tianheng Island. The confessional documents, the rank of General Wude, and the bronze medal of the unicorn issued to Zhang Zhun had to wait for Zhang Zhun to eliminate the Tartars of Tianheng Island, and then go to Aoshanwei to collect them.

A slight smile appeared at the corner of Zhang Zhun's mouth, and he said unhurriedly: "Lord Lin, I don't know how sincere Lord Zhao is?" ”

Lin Renjie hurriedly said: "Very, very, very sincere." ”

The corners of his mouth smiled slightly.

Very sincere?

Is it true?

You want me to clean up the Tartars on Tianhengdao first, help you wipe your buttocks clean, and then call me to Aoshanwei, ambush the soldiers, and fight with knives...... I don't want to think about it, when Lao Tzu was young, how many martial arts novels did he read? Will you be fooled by such a routine? Isn't that insulting my IQ?

Zhang Zhun smiled and said, "Thank you, Lord Zhao, for your kindness." ”

Lin Renjie breathed a sigh of relief.

This errand was quite smooth, and Zhang Zhun didn't make anything difficult. Also, rebellion, trouble, rebellion or something, isn't the ultimate goal just to mix glory and wealth? As long as the goal is achieved, why bother? It seems that this Zhang Yulin is also a person who knows how to advance and retreat! With Fushan City in hand, it should also be satisfied.

Who knows, he didn't be happy for long, and then he heard Zhang Zhun smile coldly and said slowly: "But! I don't accept the appeasement! ”

Lin Renjie was taken aback, and the happiness just now suddenly came to naught.

What the? You don't want to be appeased?

Lin Renjie hurriedly said: "Yulin, you are acting rashly!" ”

Zhang Zhun smiled coldly and said undoubtedly: "I, a thousand households, don't need him to appoint." Because, I am now a thousand households. Whether he appoints it or not, I'm a thousand households now! If you want to appease me, give me the position of commander of Ao Shanwei! ”

Lin Renjie was stunned and said, "Yulin, you ...... You are crazy. ”

Zhao Yinying himself is the commander of Aoshanwei, if you Zhang Zhun are the commander of Aoshanwei, where will he go? Didn't you deliberately ask Zhao Yinying to leave it alone? If Zhao Yinying agrees to your conditions, wouldn't it be equivalent to hanging herself?

Zhang Zhun said calmly: "Old man, I'm not crazy, I'm sober!" Just tell them what I say, as it is. If they accept, I won't make trouble, and I can destroy the Tartars of Tianheng Island. If I don't agree, I'll do my own thing, and I have nothing to do with them. ”

Lin Renjie was speechless.

This Zhang Yulin is really a stone in a pit, smelly and hard.

With the experience of exchanging hostages, Lin Renjie knew very well that since Zhang Zhun proposed to command the envoy of Ao Shanwei, it was to be decided. If you don't agree, the appeasement will not be completed at all. However, the commander of the guard is an official position of the third grade, and only the military department can decide. It is even more unlikely that Zhao Yinying will hand over his position. Therefore, it is definitely impossible for Zhang Zhun to agree to this condition. Since it is impossible for either side to do it, then ...... I really ran away in vain.

Zhang Zhun sat down and didn't say a word.

Lin Renjie had no choice but to leave with a stupid farewell.

…… As soon as the negotiator left on the front foot, Liu Baoyu came to Zhang Zhun on the back foot to discuss the planning of Fushan City.

Liu Baoyu, Yang Liren, Hou Shanping, Liu Hang, Wang Mingyu and several others have discussed this issue many times, and they have also invited some backbones of the Xia Sect to discuss and revise some of the details many times. Now, I finally came up with a more complete plan.

Fushan City is definitely going to be expanded, this is the consensus of everyone in the Shengxia Sect. The current Fushan City can only accommodate about 10,000 people at the same time. With the increase in population, the current Fushan City has become a little crowded. There was no extra place for shops to settle in, which affected the development of commercial trade. Therefore, the expansion of Fushan City is imperative. However, different people have different opinions on how big it should be.

The most populous cities in the Ming Dynasty were undoubtedly Yanjing and Nanjing. Among them, Yanjing's registered population exceeds 1.2 million. Counting the black households and the floating population, there should be about 1.5 million. At that time, it was definitely a first-class big city. Nanjing's population should also be about one million. There are at least twenty or thirty cities with a population of more than 500,000.

Zhang Zhun meant that it was necessary to plan in advance, according to the planning of large cities with more than 500,000 people, and put it in place in one step, so as not to continue to expand in the future and waste the people and money. However, Liu Baoyu felt that this plan was too ambitious, and the funds needed to be spent were too much. 500,000 people, that is a big city like Jinan and Yanzhou, even if it is Dengzhou Mansion, Dezhou, Linqing, and Jining, there are no 500,000 people.

However, Zhang Zhun insisted on the planning of this mega city. Zhang Zhun believes that although there are less than 20,000 people in Fushan City at present, with the continuous migration of foreign population, it will definitely eventually break through the 500,000 mark. When the time comes, not only will people from their own country arrive, but people from other countries may also come. His ultimate goal was to build Fushan City into Qingdao, the largest military port, the largest trading port, and an international metropolis in later generations.

It is precisely because of this grand goal that Zhang Zhun asked Liu Baoyu and them to plan the distribution of the city. At present, the area around Fushan City is basically wasteland, and there is only a small amount of arable land. If we don't make a plan at this time and include these wastelands in the scope of urban construction, in a few months, these wastelands will be reclaimed into arable land, and there may even be many people building houses on them. When the time comes, if you want to expand the city, you will have to destroy the arable land and demolish the houses.

Well, because of the problem of demolition, Zhang Zhun, who suffered a big loss, is indeed a little sensitive to this issue. Therefore, he insisted that the land be controlled in advance to avoid later demolition. This is one of the reasons, and on the other hand, it is Zhang Zhun's ambition. How magnificent and beautiful Qingdao was in later generations, Zhang Zhun knew very well. He was bent on replicating a magnificent and beautiful city of Qingdao in the Ming Dynasty.

The cities of the Song Dynasty were quite planned, and the sewers built during the Song Dynasty could still be used after a thousand years, which can be called a miracle of architecture. However, the urban planning of the Ming Dynasty was more messy. Even the original Nanjing was demolished and rebuilt, built and demolished. In many places, it looks like a leper, quite ugly. The beautiful Qinhuai River has also undergone many renovations to have what it is today. If you can do it in one step when you first build the city, a lot of money, a lot of manpower and material resources in the future will not be wasted. Cities can also be built more beautifully.
