"I don't know what the disadvantages are. Pen & Fun & Pavilion www.biquge.info" Tokugawa Iemitsu hurriedly asked.

"Does His Royal Highness the General know the legend of the 'Peach Blossom Spring'?" Zheng Sen didn't answer directly, but asked.

"Of course I know." Tokugawa Iemitsu said, "This is the masterpiece of Mr. Tao Yuanming, a great poet of your country, I remember when I was young, my father asked me to recite it, and in a blink of an eye, it has been decades." ”

"Can the general remember, what is it like for the people in the Peach Blossom Garden to be isolated from the world for a long time?" Zheng Sen asked with a smile.

"Naturally, 'I don't know if there is a Han, regardless of Wei and Jin'." Tokugawa Iemitsu said, "I know what Zheng Ji means, so I opened a place in Nagasaki to trade with outsiders, so as not to know nothing about outside affairs." ”

"This is indeed the general's foresight, but there are some things that are difficult to know just by guarding the port trade." Zheng Sen said, "This is especially true for things related to the military. General, if the people in the Peach Blossom Land also have an army, what kind of weapons should their army use, and what kind of tactics should they use? Think about it, if they only communicate with the outside through a small shop, how much can they know about how the outside world fights? ”

Seeing Tokugawa's thoughtful expression, Zheng Sen continued: "When the people in the Peach Blossom Garden entered that cave sky, it was still the Qin Dynasty. The Qin Dynasty still used bronze swords. In the Jin Dynasty, the weapons of 100 steels were already being used outside. Bronze weapons are almost vulnerable to hundreds of steel-made weapons. More importantly, they are still using the tactics of the pre-Qin, but the tactics of the pre-Qin are completely different from those of the later generations. Not to mention anything else, during the Qin Dynasty, the cavalry still had stirrups or not, and they could only play horse archery, but could not directly charge and kill. And the general also knew that mounted archery could only use a soft bow, and the lethality was quite poor. But by the Jin Dynasty, there were already stirrups, and the cavalry had a way of attacking. If the army of Peach Blossom Land did not know at all that other people's cavalry could charge directly and fight hand-to-hand combat on horses, what would be the result, and the general could imagine it. ”

"One thunderous blow, one defeat." Tokugawa said, shaking his head.

"In the last few decades, it has been a time of great development of all kinds of weapons and all kinds of combat technologies, but in a few years, weapons have changed more than in the previous hundreds of years." Zheng Sen said again.

Yanagi Shibei listened and said in surprise: "Has there been such a big change in the past few years?" Can Zheng tell us about it? ”

Zheng Sen nodded and said, "So I'll trespass." A few years ago, my father defeated the Dutch fleet at Liuluo Bay, but at that time the Dutch fleet was just ordinary plywood ships, that is, armed merchant ships. And we won by fireship tactics. By the time we first engaged the Spaniards, the Spaniards already had cruisers. That is, special warships, these warships have about thirty to forty cannons, and the speed is also very fast, can reach more than eight knots when the wind is downwind, which is the unit of speed calculated by the Taixi people, and it is about a little more than a knot faster than the fastest Japanese ship. ”

Yagyu Shibei said: "The speed of the ship cannot be sustained, but the ship of the Spaniards is purely dependent on the wind, as long as the wind does not change suddenly, its speed can be sustained." Therefore, it can be assumed that the Spanish corvettes had an overwhelming speed advantage over the closing of ships. ”

Zheng Sen nodded, appreciating Liu Sheng's opinion, and then said: "What's more important is artillery, generally speaking, ordinary armed merchant ships, there are only about ten cannons, I mean the 'big guns', not those gadgets that use sub-guns." In this way, there could be about five cannons on either side of the ship's side. This density of firepower is not too terrible, it is difficult to organize a tight fire net, and the fireship still has a chance to break through their fire net. But specialized corvettes are different, not to mention that the speed of such ships makes it impossible for fireships to catch up with them in most sea areas, just talk about their firepower, a cruiser can have more than forty cannons. Twenty guns on each side, arranged on two decks, and each gun larger than that of an armed merchant ship, would be almost a storm of steel if a salvo was fired, if grapeshotfire was used. Fireships, no matter how many fireships there are, will find it difficult to break through such a firepower network. It would be very difficult to use traditional fireship tactics against such warships. Fortunately, we were prepared at that time and also built our own professional warships. This was the only way to win this battle.

And in this war between us and the Spaniards, there were two battleships with more than seventy cannons in the Spanish fleet, and the cannons on these battleships were even much larger than those on the cruisers. If it weren't for the fact that we also had the corresponding ships, it would have been difficult for us to win this battle.

It's not just the weapons that change, but also the tactics, because a change in a weapon will always lead to a change in tactics. Nowadays, if anyone is engaged at sea and still uses the old formation of a few years ago against a new, completely professional fleet of warships, the result will be very miserable. Two years ago, the Yi people in the north of the Ming Dynasty built up a naval army with hundreds of ships by bribing traitors and extorting warships and personnel from Korea. As a result, they didn't know how to provoke the Dutch, who only used two frigates, plus a few fast armed whaling ships, and in just half a day, they completely annihilated this naval army that was still using old weapons and old tactics, hundreds of warships, and less than 20 escaped. Although their commander was a traitor of the Ming Dynasty, this guy's ability was not bad, and most of their sailors were veterans of war. And those Dutch did not lose a single ship in this battle, and did not even kill a single soldier. ”

"What!" Tokugawa Iemitsu was taken aback, and Matsuura, who was more familiar with naval warfare, suddenly knelt up straight, and almost knocked over the several cases in front of him.

"Is this really the result?" Matsuura was trembling, his face white like the mask used by a guy who sang Noh opera.

"Of course it's true, it's not surprising, in fact, if it were my family's fleet, it would be able to achieve such a result." Zheng Sen said, "Therefore, the biggest worry of the lockdown is that it will miss such a development." And everything related to this is difficult to obtain by keeping a port for trade. For the time being, with all due respect, if the Spaniards had not been held back by us and the Netherlands, then the sea forces they had invested in the war with us would not have been matched by the Japanese naval forces at present. In fact, there have been many changes in land warfare over the years, and if you don't know anything about these changes, the results will not be much better. And if the Japanese fleet could not restrain the movement of the Spanish fleet, it would have been difficult for the shogunate to prevent some rebels from coming and going with the Spaniards. And these rebellions, if supported by completely new weapons and training from the Spaniards, would not be impossible to start a rebellion. So, your Excellency, if you want to cut off the grip of the Spaniards that might reach Japan, it is not enough to rely on the Lockdown Order, you must have at least one fleet that can pose a certain threat to the Spaniards. ”

To be honest, Zheng Sen's words are problematic. Since it is unlikely that the Spaniards will be able to hold their territory in Asia, in fact, the threat of the Spaniards is virtually non-existent. However, Zheng Sen was not worried that the Japanese would see this, although they could certainly see it, but they also understood that the threat was not only Spain, but also the Netherlands, which was still a friendly neighbor, and even the Ming Dynasty could become a threat to Japan.

And Zheng Sen is not worried that Japan will be angry or angry because of this. The shogunate was born with a bad name, so it was natural for it to focus more on the country. He brought up these things just to tie the shogunate closer to the Zheng family's ship.

Tokugawa Iemitsu thought for a moment and said, "Zheng Ji, I don't know if there is anything to teach me. ”

Zheng Sen said: "His Royal Highness the General, the kid is just talking nonsense, where can anyone dare to 'teach' His Highness the General?" ”

Tokugawa Iemitsu didn't ask anymore, but said, "It's really a great fortune in life to rarely meet a young hero like Zheng Ji." Zheng Ji probably doesn't have a place to live yet, so it's better to stay with me for two days first. It is also convenient for me to ask Zheng Yu for advice. ”

Zheng Sen glanced at Matsuura and replied, "In this way, I will disturb His Royal Highness the General." ”

……

On the same day, Tokugawa Iemitsu hosted a banquet to entertain Zheng Sen and Matsuura. After the feast, Zheng Sen stayed at Tokugawa Iemitsu. Early the next morning, Tokugawa asked people to invite Zheng Sen again. Zheng Sen followed the visitor into a garden.

"Mr. Zheng, His Royal Highness the General is in the pavilion over there, please come with me." That bushido.

Zheng Sen looked over and saw that there was a pond over there, and there was a small pavilion in the center of the pond, which was far away from the shore and was connected to the shore by a small bridge that twisted and turned.

The samurai led Zheng Sen across the bridge to the pavilion, and then retreated until he reached the entrance to the bridge, where he guarded.

When Zheng Sen entered the pavilion, he saw Tokugawa Iemitsu and Yagyu Shibei sitting there playing chess. Seeing Zheng Sen come in, both of them raised their heads and nodded to Zheng Sen, but they didn't say anything. Zheng Sen didn't say much, and walked over directly and sat down beside the two of them to watch the game of chess between the two.

At this time, one of Tokugawa's chess pieces was attacked by the enemy, and after some struggle, he finally saw two eyes, but he lost some officials, and if he wanted to take the risk to protect the interests of the officials, he was afraid that his life would become a robbery. Therefore, Tokugawa put one hand in the chess piece jar and grabbed it with a crackling sound, but he couldn't make up his mind for a while, just sighed vigorously.

Zheng Sen didn't say anything, just watched from the side. In fact, Tokugawa's chess situation was not bad, and he was slightly ahead overall.

Tokugawa finally sighed, dropped a shot, and laid out his two eyes safely.

The two went down for a while, and finally Tokugawa narrowly won a glance.

"I'm sorry, I made Zheng Ji wait for a long time." Tokugawa, who won the chess, apologized to Zheng Sen, who was sitting on the side, with a smile on his face.
