Of course, Zhu Guobi and Liu Kongzhao were not only concerned about the life of the sailors and soldiers at sea, but also about how much silver they could earn from the sea trade with the northern daimyo of the Japanese state.

"The tea we buy in Jiangnan is generally a pound or two of silver, and the silk is about the same price, porcelain, a vase from an official kiln is only a few taels of silver, but if the tea and silk are transported to the Wa Kingdom, they can be sold for about six times the price, and the porcelain is even higher, because there are many Xiyi who purchase our porcelain in the Wa Kingdom."

According to the records of the Ming Huidian, the export price of blue and white porcelain plates is 500 guan each, 300 guan per bowl, 500 guan per bottle, and 1,500 guan each in the sea of wine. Each bean celadon plate is one hundred and fifty yuan, the bowl is one hundred percent, and the bottle is one hundred and fifty percent, which means that the price of porcelain can be ten times more profitable if it is traded.

"Then will the Japanese side use silver or copper coins to settle our goods?"

The Xungui of the Southern Capital and the Donglin Party do the sea trade business together, and the profits they can get are not high, after all, most of the heads have been taken away by the Zheng family and the Donglin Party, after hearing the huge profits mentioned by Qian Anning, Zhu Guobi and Liu Kongzhao's eyes are a little bloodshot, and the most critical issue is raised, that is, the business of buying and selling copper coins in collusion with Li Xingzhi.

"Baoguo Gong, the Wa Kingdom is the same as our Ming Dynasty, one tael of silver is worth the same money, but if we transport copper coins to the Wa Kingdom, I am afraid that we cannot exchange them at a one-to-one price, and we must always give an eighty-nine discount!"

Exchanging copper coins for silver is an extremely lucrative business, coupled with the low copper content of the inferior copper coins made by the Linqing Manufacturing Bureau, Li Xingzhi, who is not good, actually intends to exchange lead for silver, and even fools can know how big the profit is.

"Mr. Qian, you go and deal with it at the Linqing Mint Division, the price is set at three cents, I think those corrupt officials will not refuse, it's a big deal that you give them an extra kickback."

Linqing is close to Gyeonggi, which is the choke point between Shandong and Beizhili, and Li Xingzhi naturally cannot plunder at will.

Moreover, robbing the Mint Division of Linqing, that is, a hammer deal, it is better to spend some silver to buy, after all, if the Jingbei Army makes fake money by itself, the cost may be higher than that of purchasing the imperial court's money.

The purchase of copper coins worth nine cents of silver will make the profits of this fake money business more than 20 times that of a terrifying amount, which makes Zhu Guobi and Liu Kongzhao speechless.

Donglin's gang of dog officials and the Zheng family in Fujian, you take our silver, do more than ten times the profit business, and only give us 20% of the profit, which doesn't treat us as human beings at all!

Zhu Guobi will greatly resentful of his partners in the south, and will think more and more that Li Xingzhi is a trustworthy partner in business.

In addition to inspecting the transport ship, Zhu Guobi also visited the Jingbei Military Naval Division Town and the storage warehouse of the Lifting Division in Huangdao.

In terms of naval warships, the Jingbei Army Naval Division Town currently has 20 No. 1 Fu ships, each of which carries 120 officers and men, and is equipped with two Hongyi cannons, 16 jack franc machines, five trebuchets, four bed crossbows, and 50 arquebuses.

There are 30 No. 2 Fu ships, each carrying 80 officers and soldiers, 14 thousand pound Franc machines, and the rest of the equipment is similar to that of the No. 1 Fu ship.

In addition, Zheng Zhilong also provided fifty bird boats for the Jingbei Army after getting the coveted position of the Fujian General Army, but Zheng Zhilong played a careful trick and dismantled all the artillery on these warships, in order to make up for the shortage of artillery, the Manufacturing Bureau was building it day and night.

Although there are only more than 100 warships in the Jingbei Army Naval Division, compared with the Zhengjia Naval Division, it is like a firefly against Haoyue, but in the northern part of the Ming Dynasty, compared to the Daimyo in the north of the Eastern and Wa Kingdoms, it is a giant existence.

Li Xingzhi's goal is not just a sailor from the east, replacing the Zheng family and becoming the ruler of the sea routes in Southeast Asia is the ultimate goal of the Jingbei Army's naval division, building more warships and training more naval soldiers is one of the most important tasks of the Jingbei Army.

"Mr. Qian, why has my Sailor Town only built more than forty warships in the past year and a half?"

Li Xingzhi doesn't know much about building wooden warships, but it is obviously not logical to build such a small warship in the past year.

"Marshal, you don't know, according to the shipbuilder, the wood of this shipbuilding must be dried in the shade, and then it can be used to make the hull, these woods must not be dried, in that case, the hull is easy to crack, although our army marshal's mansion has prepared a considerable amount of wood, but these materials can just be used, and it has been our best to build dozens of them before, which is also the main reason why we can't trade on a large scale."

Qian Anning was a little depressed, the establishment of the City Ship Division was proposed before the Jingbei Army set out to conquer Huguang, what can be done in the past six months?

"Qian Tiju, Benjue asked you, since the wood you just cut down can't be used, how did you build these dozens of warships?"

Since the Jingbei Army's naval division was formed not long ago, the quality of these dozens of sea ships built within half a year is debatable.

"Uncle Sincerity, the Fu Boat built by our Jingbei Army is made of wood dismantled from the boats and transport ships of the Dengzhou Naval Division, and these woods have been used for more than ten years, so they are naturally unusable."

Qian Anning is always answering questions, and obviously has put a certain amount of effort into the work of the city's shipping department.

"It's also a good way to use the old ship for a new purpose, who is the master who provided this plan Mr. Qian, the commander should be clearly rewarded, and he knows the whole army."

Li Xingzhi is obviously willing to spend money on those who can provide constructive proposals and make contributions to scientific and technological innovation.

"Dashuai, this suggestion was provided by Master Chen, an old boatsmith in Beiqinghe, according to him, his family has been working as a boatsmith in Longjiang Bao Shipyard since the Taizu period, and it has now been passed down to the ninth generation."

"What, Longjiang Bao Shipyard?"

Qian Anning's words shocked Li Xingzhi, during the Yongle period of Ming Chengzu, he sent the great eunuch Zheng He to the Western Ocean seven times, and the transport ship used was the treasure ship produced by Longjiang Bao Shipyard.

According to the "Three Treasures Zhengyi Collection", the treasure ship No. 63 is 44 zhang 4 feet long and 18 zhang wide, and the middle ship is 37 zhang long and about 15 zhang wide.

That is to say, at the beginning of the Ming Dynasty, the Ming Dynasty was able to build a large transport ship with a length of about 140 meters and a width of 50 meters.

However, shortly after Zheng He's death, during the Tianshun period of Yingzong of the Ming Dynasty, Liu Daxia, the secretary of the Ministry of War, in order to prevent Emperor Yingzong's plan to go to the West again, actually burned the charts stored by the Ministry of War and the treasure ship drawings of the Ministry of Industry, so that the hard work of the three treasure eunuchs and countless craftsmen of the Ming Dynasty came to naught, which is really sad and lamentable.
