The carriage soon arrived in front of the shogunate, that is, in front of the official residence of the "Seiyi Shogun". Pen? Interesting? Pavilion wWw. ｂiquge。 infoThe so-called shogun, the full name of which is "Seiyi Shogun", was originally a temporary official position in the earliest days, and the so-called "I" refers to Ezo. Later, however, with the rise of the samurai family and the decline of the emperor's public family, the position became fixed and became the de facto ruler of the whole of Japan.

The carriage stopped in front of the mansion, and Yagyu Jubei jumped out of the carriage and pulled the door, and Zheng Sen and Matsuura Dong got out of the carriage. Yanagi led them into the mansion, bypassing a screen, then through a courtyard, and behind it was a large courtyard, directly opposite a main house, where Tokugawa Iemitsu would receive guests. Zheng Sen saw that at this time, there was already a middle-aged man dressed in gorgeous clothes waiting at the foot of the steps of the main house with a group of followers.

"This is probably the third generation of Tokugawa Iemitsu." Zheng Sen thought, "It's very polite to greet each other like this." ”

Sure enough, the Yanagi Ten Guards first stepped forward to salute the man and said, "The Yanagi Ten Guards are three strict to meet His Excellency the General." The subordinate was ordered to greet His Royal Highness Matsuura and Mr. Zheng, and fortunately fulfilled his mission. ”

Tokugawa Iemitsu nodded and said, "It's hard work." Then he stepped forward and said to Zheng Sen: "But Mr. Zheng Sen is really a young hero." ”

Zheng Sen also said: "He should not be praised by His Royal Highness the General." ”

Tokugawa turned to Matsuura again and said, "Matsuura Hall has worked hard all the way. ”

"Don't dare to labor the general to inquire." Matsuura also hurriedly said.

Tokugawa Iemitsu smiled, then stretched out his hand, took Zheng Sen's hand and said, "Mr. Zheng, please go in and talk." ”

Everyone entered the main room, and the guests and hosts sat down, and Tokugawa first asked about Matsuura's journey over.

"I heard that Matsuura Hall came here on Mr. Zheng's boat this time? I don't know what the difference is between Mr. Zheng's ship and Matsuuraden's own boat. ”

Matsuura hurriedly said, "What the general said is that the minister did come on Mr. Zheng's boat. How can Xiao Chen's broken boats be compared with Mr. Zheng's boats. Zheng Ji's ship is as big as a mountain, and one can top dozens of ministers, and only the general's 'Tianxia Pill' can be compared to it. ”

Tokugawa Iemitsu shook his head and smiled: "What's going on with the 'Tianxia Pill', others don't know, how can Matsuura Hall not know." It was a ship that could not go out to sea, but could only be used to defend the harbor. Zheng Ji's ship came all the way from Daming and crossed the endless sea. Where is the 'world pill' can be compared. ”

He turned to Zheng Sen again and said, "I heard that Zheng Ji is on a Dutch-style ship this time?" I don't know which is better, the Dutch ship or the Ming Fu ship? ”

Zheng Sen said: "Your Royal Highness, the ship I am on this time does refer to some designs of the Taixi countries. As for the advantages and disadvantages of Hefufu, it is a little complicated, and I wonder if His Royal Highness the General is interested in listening to me. ”

"How can this not be interesting?" Tokugawa Iemitsu said, "Matsuura-den also knows that I've always liked ships. ”

"Let's just say that the ship I'm on this time and the Fubune are two completely different ships in terms of purpose." Zheng Sen thought for a while and said, "The Fu Ship is a multi-purpose sea vessel, which can be used both to transport goods and for naval warfare. But, fundamentally, it is primarily a vessel used for transportation. The Fukufu ship is relatively short, relatively wide, and if the same amount of wood is used to build the Fukufu, its cargo volume is significantly higher than that of the Taixi-style ship. Moreover, the Fu ship uses hard sails, which can make the wind come from all directions, and the ability to sail against the wind is also stronger than that of the Taixi ship.

But General, you may know a Chinese saying that says, 'Everything is clear, everything is loose.' This means that a person's energy is limited, and if some energy is spent in every direction, then he must be a generalist, but there is nothing really proficient in it. The same goes for the Fuship, which is still a cargo ship in the final analysis, and although it is not impossible to use it in naval warfare, some of its structural weaknesses make it inferior to those Tessie ships in naval warfare. Just like the Tessie ship is not as good as the fortune ship when it comes to transporting goods.

However, my ship 'Zhenjiang' this time is different from them, it is a professional warship. From the time of its design, the ship was not designed with any merchant marine purpose in mind, and all its performance was designed for combat. So my boat is about twice as fast as a regular Fukubune, and the hull is much stronger than a normal Fukubune......"

After listening to Zheng Sen's words, Tokugawa Iemitsu said: "In this way, wouldn't it be ...... if those warships of our Japanese navy were against such a professional battleship" Speaking of this, he looked around, his eyes fell on Yanagi Shibei's body, and then said: "Isn't that like letting me go to compete with Yanagi Jun in swordsmanship, if Yanagi is serious, I won't be able to take a sword......

"If Japan relies on the support of the harbor batteries, it is not completely impossible to fight against this kind of special warship." Zheng Sen said.

"Zheng Ji, I have read your "Naval Strategy", which mentions that the fundamental purpose of the existence of the fort is to liberate the fleet, so that the fleet can be freed from heavy defense tasks and used for critical operations. In land-to-sea defense, if you don't have a fleet that can be used for battle, you will be very passive. Because it is impossible for anyone in this world to have the financial and material resources to place batteries on every coast, and the army is naturally incomparable with the navy in terms of marching ability. So......" Yagyu Shibei said suddenly.

Zheng Sen listened, nodded and said, "That's true." However, if there is enough base support, and the protection of the battery, even a smaller fleet is enough to fight a stronger fleet, and my father defeated the Dutch by taking advantage of the lack of base support in the Dutch fleet. Another example is today...... Yagyuden must know that my family is currently fighting the Spaniards. ”

"Indeed." Yanagi Shibei nodded.

"I wonder how much Yanagiuden knows about Spain?" Zheng Sen asked again.

"I heard that it's a big country in Tessie." Yagyu Shibei Road.

"Do you know how big this Spanish country is?" Zheng Sen asked again.

"It's not clear." Yagyu Shibei replied.

"Spain is not only a large country in Thailand, but also the largest country in the world in terms of land area. Can the Tessie people's earth theory and heliocentric theory Yanagi Temple be understood? Zheng Sen asked again.

"I know a little."

"That's easy to tell." Zheng Sen nodded and said, "Spain has a vast territory, and it is the world's first empire on which the sun never sets. ”

"The sun never sets on the empire? What does that mean? Tokugawa asked.

"Your Highness Tokugawa, 'the sun never sets' means that its territory covers the entire earth, and when the sun sets in one of its territories, it rises in another of its territories at the same time, so that at any time, the sun will always shine on its territory, and in its territory, the sun will never set. That's what it means to 'the sun never sets.'" The Spanish Empire destroyed countless countries and its territory was vast, even surpassing the empire of Genghis Khan. It's just that this empire, unlike Genghis Khan's empire, the fundamental strength of Genghis Khan's empire was his army, while the most fundamental strength of the Spanish empire was not the army, but the navy. The strength of the Spanish Navy is also similar to that of Genghis Khan's army. Its navy has as many as a thousand professional warships, and there are thousands of other auxiliary vessels, the kind of armed merchant ships you have seen before before the Japanese sea is banned. Zheng Sen explained.

"How strong is it? So how did Zheng Ji defeat a country like Spain on the previous two occasions? Tokugawa Iemitsu was taken aback.

"As the old saying goes, 'Though the whip is long, it is not as long as the belly of a horse.'" Naval operations, like the army, depend on the supply of food and grass. "This is the weakness of the Spaniards. For example, today, if the general had a million soldiers, could he use them to attack a foreign land thousands of miles away? ”

"This ......" Tokugawa Iemitsu didn't react for a while. Although he had the honorific title of General Zhengyi, he did not have much experience in warfare, and Japan had never used a million troops to attack a foreign land thousands of miles away.

"I can't." However, Yanagi Shibei immediately replied, "Zhuangzi said: 'Those who are suitable for a hundred miles will have food; For those who are suitable for thousands of miles, gather grain in March. 'Mobilizing an army of millions, and fighting thousands of miles away, the amount of grain required is really difficult to calculate, and I am afraid that the accumulation of several generations may not be enough. And the number of people needed is at least ten times that of the army. Even if all the men in Japan were sent to transport grain, it was not enough. Where in the world is there a reason for the army that can prosper millions of people and expedition thousands of miles away to foreign lands? ”

"Not bad." Zheng Sen first praised, "The navy can use ships to transport food and supplies, and it relies less on baggage than the army, but it is not without limits. If there is no port near the battlefield to support and cannot be effectively supplied, there will be a large army, but the number of troops that can be sent is limited. Spain is fifty or sixty miles away. It is a method of strategy, which is to occupy an overseas island first, and then use it as a base to operate on a daily basis, trade in the surrounding area, and preach. One uses this to spy on the virtual reality, the other is to seek internal response, and the third uses this to enrich the base. When the reality is known, the inside should have been obtained, and the reserves of the outer island base are sufficient to support its army, it is the time to enter the army in a big way. Today's Spain first took Luzon, thinking that it was accumulating, and he may not have the heart to peep into Japan and even China. My family is in a hurry to chase it, but also to eliminate the great trouble for the Ming Dynasty and Japan. ”

Yanagi Shibei listened to it and said in horror: "The method of the Spaniards that Zheng Ji said has been used in Japan. For example, through trade to get a glimpse of the truth, such as through the mission to seek internal response. It's all true. Fortunately, the general was wise and expelled from Japan. Otherwise, Japan is in danger. However, the occupation of Luzon by the Spaniards was really a problem for the henchmen. Fortunately, there is Zheng Ji, who can expel him. ”

Tokugawa Iemitsu listened to Yanagi's evaluation of his forbidden sea and closed country, but he was very proud, and said: "The Spaniards are treacherous and vicious, how can I not know that I only hate some people but do not know what to do, and I still have to deal with them." ”

When Matsuura Dong heard this, he hurriedly said: "The minister was originally shallow and ignorant of the insidiousness of the Spaniards. Only today did I know that if it weren't for the general's wisdom, I was afraid that the disaster of the Yuan Kou would come again. Those who save the Japanese, the generals, too! ”

"Although the general's ban on the sea and the country is also a good way, the foreign minister thinks that there are some drawbacks, and he must not be guarded against." Zheng Sen said so.
