Once the Peksan cannon is made, not to mention invincible, it will also be very useful to siege the city on land. Most of Europe's city walls struggled to withstand the continuous slamming of 68-pound iron balls. Unless, it is a particularly thickened city wall, which can barely resist it.

Although the caliber of the Pexan cannon is huge, its weight is not very heavy because of the design of the shortened barrel. According to Marin's memory, the length of the Pexan cannon seems to be only 2.84 meters, which is less than the 3 meters length of the 18-pound Hongyi cannon. Therefore, although the poundage is 3.77 times that of the Hongyi cannon, the total weight of the Peksan cannon is 3.4 tons. This weight is much lighter than the heavy artillery of World War I. With a few more horses, you can still pull under the enemy's walls.

It just so happens that Marin's ranch is now in full swing to breed tall and strong shire horses. This heavy horse, naturally adapted to pull heavy artillery. When the time comes, the heavy task of getting the rapeksan cannon under the enemy's walls will be handed over to Sharma.

It's just that this super heavy gun, with a caliber of up to 220 mm, seems to have a very large recoil. Even the largest 500-ton warship in the Beihai Kingdom is estimated to be difficult to withstand its huge recoil.

You must know that in the middle of the 19th century, when the Peksan cannon appeared, the tonnage of the main wooden battleships at that time had already reached three or four thousand tons. For example, the "Victory", a battleship of the late 18th century, had a displacement of more than 3,500 tons.

Moreover, the battleships of that time, in order to adapt to the strong recoil of large-caliber guns, the hulls were reinforced. Especially the keel part, so as not to shake the battleship itself apart by recoil during the artillery battle.

Therefore, even if there is a Pexan cannon, Marin must have a solid warship to match it. Therefore, Marin had to give an order - to mobilize the best group of designers in the shipbuilding industry of the North Sea State to design the strongest warships. Moreover, the displacement is required to reach more than 1,000 tons. Otherwise, it is difficult to adapt to the recoil of such a heavy artillery as the Peksan gun. If the ship is too small, even if the structure is reinforced, it is useless, and the huge recoil of the Pexan cannon can cause the hull to roll over......

In short, neither the development of the Peksan gun nor the development of a 1,000-ton warship can be made in a short period of time, and it may take 10 or 8 years.

But Marin could afford to wait, and was willing to wait. Because, when this ultimate weapon and warship are made, the sea will be surnamed Ma. Get a few more of these warships out, and Marin can only learn from Deng Chao to sing "How lonely is invincible" at home......

When the time came, Marin decided to send such an invincible armada to encircle the Portuguese capital Lisbon and sink all the Portuguese warships in Lisbon. Then, Portugal was forced to sign unequal treaties. For example, ceding South Africa to him or something......

Marin didn't have much interest in Africa, but he couldn't ignore the tens of thousands of tons of gold in South Africa. Therefore, once the bombing force comes out, going to the port of Lisbon, Portugal to wash the floor is what Marin will definitely do. Moreover, Marin also intended to scare Spain by beating Portugal in order to achieve the goal of maintaining maritime supremacy.

But for now, Marin can only think about ...... More than a dozen 500-ton warships in the Beihai Kingdom are very powerful, but the scale is too small after all. The Portuguese fleet, even if inferior in quality, could win by relying on its numerical superiority. Therefore, Marin can only pretend to be a transparent person silently, so as not to be taught to be a human being......

……

For the sake of research and development and secrecy, Marin ordered that the research and development team that developed the Pexan cannon and the thousand-ton warship be all moved to New York Harbor in the Americas. As a result, it will be difficult for the rest of Europe to know any of the news.

Moreover, it is also very convenient to develop warships in the Americas. Because, in the colony of New York, there are too many red oaks suitable for shipbuilding, and they are all air-dried for more than two years. In the past, the R&D team only had to direct the shipbuilders there to build big ships. It doesn't matter if the wood is wasted, because there are dozens of meters of red oak logs everywhere. The red oak logs, which are suitable for building large ships, are scattered everywhere. Even if you use it as firewood, you don't have to worry about wasting it. Because, the whole land is full of these towering trees......

……

When Marin was imagining how to dance and sing "How lonely is invincible" in the future, information came from the Italian side - John. Raffi turned to Marin for help, and he needed to offer advice to Louis XII to solve his current predicament......

Speaking of which, Marin's previous plan is now considered a failure. For example, Marin originally planned to let the Spanish army and the French army fight on the Italian peninsula, and it was better to fight for both sides and fight the dog's brain.

But the problem is, Gonzalo. Morality. Córdoba, the Spaniard, is too careful and too obscene. People are not willing to attack the city desperately at all, they only know how to dig ditches and besiege the city, and their patience is very good.

The French originally expected the Spaniards to storm the city of Naples, and even did not hesitate to send people to Spain mainland to use agitation. However, Gonzalo. Morality. Córdoba found a way to use French farmers as cannon fodder to make an offensive appearance, and cracked the French strategy.

Now, watching the French soldiers on the city walls hurt the French peasants every day, Louis XII was so depressed that he wanted to vomit blood. But he couldn't do anything. The previous "return to the horse gun" tactic was very useful, and it wiped out tens of thousands of Spanish troops at one time. However, it can only be used once. From the second start, the Spaniards took out their chariots to defend against cavalry charges......

Therefore, the current French are in a dilemma and do not know what to do. Because of his previous performances, Louis XII now put his trust in John. Rafi asks him every day. Can John. Raffi knows what kind of resourceful man he is. The strategies he offered were all from the Marlin Sect......

In desperation, he could only release the carrier pigeon back in the middle of the night and ask Marin for advice......

"It's really not like this, it's always so deadlocked, it's not in line with my own ideas at all!" Marin also had some headaches about the current situation. So, he decided to change all that......

……

Marin thought about it and found that the biggest reason for the current impasse was Gonzalo. Morality. Córdoba is a Spanish star.

This thing has become old and refined, and he doesn't care about any honor and face at all. As long as he was in one day, it would be difficult for the Spanish army to foolishly storm the city.

Therefore, if you want France and Spain to play dog brains, you must transfer this old thing......

And how to transfer such a famous general? Marin immediately thought of the famous "Battle of Changping......

At that time, the famous general Lian Po of Zhao was also with Gonzalo. Morality. Córdoba, like that, is not fooled, insists on confrontation, and never fights, so that the god of war is very temperamental.

Later, the Qin State adopted a counter-strategy, spreading rumors that Lian Po was not good, and Zhao Kuo, who could only speak cannons, was very powerful, and the people of Qin were afraid of Zhao Kuo...... Then, King Sabi Zhao was fooled, replaced Lian Po, and replaced Zhao Kuo, the king of mouth cannons, so that Zhao was defeated and lost 400,000 strong men, and his vitality was greatly damaged, and he could no longer fight against Qin alone......

Marin decided to draw a scoop with a gourd and come up with a counter-plot to get the Spanish side to deal with Gonzalo. Morality. Córdoba became dissatisfied and transferred him out. Only then will there be a possibility of a decisive battle between the two sides......

Marin thought all night, wrote a lot of measures, and replied to John with a carrier pigeon. Rafi. He wrote it in Morse code, not that the spy couldn't read it at all, but he wasn't afraid that the carrier pigeon would be intercepted. These counter-intriguing measures were soon sent to John. In the hands of Lafite, it was then presented to Louis XII. Then, the French mainland also moved, and a large number of orders were sent to Spain. Because, as a neighbor and adversary, France has many spies in Spain, and it is very suitable for this matter......
