In fact, the weapons and equipment of the Tiance army are very different from those of the Dutch, so they don't need to be very clever in their tactics. Wang Yue asked everyone to brainstorm ideas, also to improve their vision and military talents.

Wang Yue looked at the map and reconnaissance pictures, pointed to the Chiji Fortress and said: "Our army rushed through the Luermen from the north lane, and after occupying the harbor, we will first take the Chichi Fortress, and then besiege the city of Gelanza, and we must complete the combat mission within three days." ”

In fact, the offensive line mentioned by Wang Yue was basically copied from Zheng Chenggong and repeated the reconquest of Taiwan. Of course, the strength of the two cannot be compared, and the strength of the Tiance Army is overwhelming.

"Yes!" The officers answered, and the military discussion ended.

The Dutchmen of Putmans and Gesharan had no intention of leaving. Instead, they used this time to strengthen their armaments.

This result was inevitable, and it was impossible for the Dutch to abandon the stronghold of the Grand Man. Once you lose here, it is likely that you will lose the entire Japan and Daming market, which is an unacceptable result.

For Putmans, the luck was terrible. In its reply, the East India Company stated that his concerns were unfounded, and that he did not believe what Putmans had described that the Ming already had a steel giant. Moreover, it was impossible for the Ming to challenge the Dutch at sea, and considering what he said, he transferred two armed merchant ships from Batavia as a supplement to his strength.

At this time, Putmans was completely desperate, and after writing back again about what had happened to him, he continued to prepare for stubborn resistance.

The trip to Tamsui saw so many steel giants, although he didn't see many guns, but the pressure on him was still very great. He saw the rifle held by the soldiers of the Tiance Army, and although he couldn't see the power, he could see that the manufacturing process was very sophisticated.

The Spaniards' Keelung City was broken in one day, which showed that the Tiance army was very strong, and he had to make all preparations.

As the days approached, Putmans, who was rearming for battle, had a special guest.

"Oh...... Mr. Zheng, welcome to you, I heard that you have recently made another big deal, is that right? Putmans stood up and opened his hands to the visitor to hug him, but was dodged by the visitor.

This man with elegant manners was Zheng Zhilong's henchman Zheng Bin, and after seeing Zheng Bin slightly avoid, he smiled bitterly: "Your Excellency the Governor, we Han people are not used to such courtesy, I have received your wishes, as for the hug, it will be exempt." ”

"Haha...... You Han people are just too shy. Putmans laughed loudly, not reluctantly, and then sat back in his seat, and said to Zheng Bin with bright eyes: "You Han people have a saying that you don't have anything to do and go to the Three Treasures Palace, I don't know what advice you have when you come to me this time?" ”

Zheng Bin, who had dealt with the Yi people a lot, was not surprised by Putmans's directness, and he also said straight to the point: "Your Excellency the Governor, our eldest brother and the first official are about to expand the strength of the naval army and build new warships, but there is a lack of artillery, so I want to buy some twenty-four-pound guns from you, the price is negotiable!" ”

After Zheng Sen and Zheng Zhibao returned to Nan'an, Quanzhou, they described to Zheng Zhilong in detail the situation of their meeting with Wang Yue, especially mentioning how huge the naval warships of the Tiance Army were, and they were huge steel ships, and Zheng Zhilong felt great pressure after hearing about it.

Regarding Zheng Zhibao's proposal to attack Tianjin Port from a distance, Zheng Zhilong vetoed it after careful consideration. Not all ships are suitable for long-distance voyages, and after long-distance voyages, physical exertion is very great, which seriously affects combat effectiveness, and secrecy is also a problem when the scale is large.

The large-scale attack on Tianjin, the gateway of the Beijing Division, has a huge impact, and even if it wins, public opinion is not good for the Zheng family.

The interests of the Zheng family are in the South China Sea and the Japanese route, and Wang Yue wants to put his hand here, that is the fundamental conflict of interests, and the struggle is inevitable. Therefore, the Zheng family has begun to prepare for the construction of more warships.

Wang Yue's move to emigrate to Taiwan has been known to the Zheng family, after all, there are too many people on the island of Taiwan who keep in touch with the Zheng family. There is no conflict between the immigration action and the main business of the Zheng family, in fact, the Zheng family is also welcome to the increase in Taiwan's population, and the increase in population also represents the active business and trade in the future.

But as the Spaniards' stronghold in Keelung was taken by the Tiance Army, Zheng Zhilong and a group of strategists came to the conclusion that Wang Yue's goal was the whole of Taiwan. Once Taiwan is encapsulated by Wang Yue, then the Taiwan Strait and the Nanyang to Japan route may be cut off by Wang Yue, which the Zheng family cannot tolerate.

Putmans asked, "How much do you want to buy?" ”

"The more the merrier, if we can, we want to buy fifty first!"

Zheng Sen and Zheng Zhibao bought a large amount of goods in Tianjin, and they made several times more profit after making a sale, so the Zheng family is really not short of money now.

"Oh God...... That's impossible! Putmans was immediately taken aback.

Before large-scale industrialization, casting cannons has always been a very difficult and time-consuming thing, and at present, bronze cannons are the mainstream of the world's artillery, because bronze has a low melting point and is easy to process.

Moreover, in this era, low-carbon steel technology was not enough, and artillery cast from steel was not up to the task of increasing bore pressure, and steel at that time was basically as brittle as cast iron.

The worst thing is that cast iron is very easy to rust, especially on ships with high salt content and high humidity. The artillery cast in bronze is not only hard, tough, but also very corrosion-resistant, very close to the characteristics of modern steel, so before the advent of sleeve cannons and Rodman mandrel cooling technology, most countries in the world used copper to make artillery.

Given that bronze was a precious metal in this era, artillery was precious even to the wealthy Dutch, so Putmans was taken aback when he heard that Zheng Bin was talking about buying fifty guns.

"God...... Do you know what you're talking about? ”

The mouth of Putmans, who was originally calm and relaxed, grinned like a hippopotamus that was only pulling teeth, and he pointed at Zheng Bin and said in astonishment: "You...... Do you know how much fifty guns cost? We have less than sixty-eight guns in the whole city of Geranza, and you want fifty guns as soon as you open your mouth, do you want to remove all the artillery in the whole city of Geranza? ”

"It's a must!" Zheng Bin's attitude has not changed in any way because of Puttmans's attitude, "Your Excellency the Governor, you should know that the forces of the Tiance Army have invaded Taiwan, the Spaniards have fallen Keelung City, and their next target is likely to be the city of Geranza, and we now have a common enemy, that is the Tiance Army." ”
