The secret of the non-rusting of the canned tube turned out to be here, Jiang Ke almost exclaimed, this technique is not recorded in the scroll of how much money it took in Huayuan, how much time, how much manual experiment.

Jiang Ke had originally heard that the mint in Huayuan was fully open, and the speed at which the money was spent was not as fast.

As early as the Qin and Han dynasties, there was a technology of tin crossing the bronze surface, which could be tin plated on a thin and light steel plate, and it should be bright and smooth. In Jiang Ke's eyes, this technique is absolutely impossible for the Silla people to know.

There are also detailed distinctions in the information.

There are more than a dozen different kinds of steel such as iron for hoes, scissors inlaid steel, ordnance steel, civil general steel, and special steel for canned tubes.

Among them, the steel used for canning barrels is impossible to become ordnance steel even if it is melted because of tin plating, and it is very reluctant to be used as civilian general steel.

Jiang Ke wrote the words canned steel on the paper, and then drew three circles heavily.

At noon the next day, Jiang Ke, who had two dark circles under his eyes, found Liu Mu.

"Lang Jun, the plan is like this. The canned cylinder steel produced by Xingzhou Steel Mill weighs three stones, one foot wide and one hundred feet long into rolls, and this thing has to be transported to another steel mill to be reprocessed into canned tubes, and its giant shearing machine and stamping machine seem complicated and huge, but there is not much advanced technology. ”

"Yes." Yanagi nodded.

These two things really don't have advanced craftsmanship, in order to increase work efficiency.

Jiang Ke continued: "Then I can't understand the two big machines of curling and crimping after reading it several times, so I have to keep it, and these two tasks can be done by borrowing a single gadget." Silla built a canning tube, which also needed a stove, a lot of labor, and a lot of tools. ”

"Go on." Yanagi felt that this was reliable.

"All the raw materials are ......transported from the Xingzhou steel mill," Liu Mu interrupted Jiang Ke's words: "Sorry to interrupt you, a new steel mill has already started production, a large steel mill originally built for the production of canned tube steel, located about 100 miles southeast of Qizhou, where there is a river leading directly to the Jiaozhou wharf. Yield...... Amazing. ”

This is not one of the information that Yanagi gave before.

Jiang Ke was even grateful in his heart for Liu Mu's interruption, which made his plan easier.

"Tsushima Island, it can actually be controlled by Datang. However, the fishermen who distributed it to the Japanese and Silla people, and according to Langjun's information, the Tsushima Strait was rich in fishery resources, so it was possible to make a large number of canned fish. The Japanese needed to buy canned food cylinders from Silla, which was an open-faced deal. ”

"And what about the other way around?" Yanagi asked again.

"Silla had nothing, and Akiki Purple Island Fukuoka could produce countless amounts of charcoal to supply Silla. Without charcoal, Silla would not have been able to make canned food tubes, let alone process fish, which would require countless spices, which would have been shipped from Yeongnam without raw materials. ”

After listening to Jiang Ke's suggestion, Liu Mu said: "There are several small islands in Samonan, Washima, which are good places to grow sugar and sugarcane, and sugar is needed for canning, even canned fish. ”

"Lang-kun, the result of this is that Silla, Hayato, and Usu are inseparable from this circle, but the trouble is Goguryeo in the north of Silla, they are red because of the benefits of Silla, and they will stir up some trouble in the fishing grounds by the sea."

"What about your proposal?"

Jiang Ke finished speaking: "Sell the ship to Silla and the Japanese people, and let them fight to the death with Goguryeo." ”

Liu Mu shook his head gently: "It's not good, once it triggers a full-scale war between Goguryeo and Silla, it will be bad for my Tang Dynasty." ”

"Lang Jun, it will never cause a war."

"Why?"

"Goguryeo is still testing my Tang Dynasty at the moment, and they are not sure about Silla. Once the Japanese participated in the armed fight against the fishing grounds belonging to Goguryeo, the Goguryeo royal palace did not dare to act rashly. The real fight will be a few years later. In the next few years, there will be many measures to deal with the possibility of a national war on the peninsula in a few years. ”

I have to admit that Jiang Ke's words are very reasonable.

Liu Mu said: "Prepare, let's go north together tomorrow afternoon, and we will go to ...... Silla. ”

The next day, Yanagi prepared to leave.

Not being able to accompany Dugu Lanruo made Liu Mu feel a little guilty, but Dugu Lanruo had the good character of a Tang woman, and showed great support for her husband to go out to work.

Wan Guifei also gave up going to Kagoshima and wanted to stay in Hangzhou to accompany Dugu Lanruo.

After leaving the sea, only two days after Liu Mu left Hangzhou Bay, he met Li Xiaogong's boatman at sea, Li Xiaogong had originally sent a group of widows to Yangzhou, and then took care of some of his official business in Jiangnan by the way.

As a result, Li Xiaogong was pulled by Liu Mu, and after Li Yuan's ship was handed over to Li Xiaogong, before Li Xiaogong asked what was going on, Liu Mu's fleet flew north with full sails.

"He ......" Li Xiaogong didn't know how to ask.

Li Yuan smiled: "Compared with many courtiers, he works more carefully. In another half a month, Wuji will bring Chang'an's secret order, one of which is for you. ”

"Uncle Huang, I'm afraid you don't know, this time it's a little too ruthless to the Japanese people."

"Is it ruthless?" Li Yuan smiled indifferently: "When you see Wuji, come and tell me, it's not ruthless enough." Now, send me to the mountain that Kogi said breathes fire every day, and what hot springs can see the sea. ”

Li Yuan's words made Li Xiaogong stunned twice in a row.

First of all, he felt that Li Yuan didn't think what happened in Wadao was not ruthless, and secondly, he didn't know what a mountain that spewed fire every day was, he hadn't been to it, and he hadn't heard of it.

It was the captain who told Lee Hyo-kung that it was a very small island near Kagoko Port.

On both sides of the conversation, the sails on the willow side were fully open, and he braved the wind and waves to a port in Silla that did not fully belong to Silla.

This place is called Kagedo, Juqisan County.

In the past, there was a small country here, called the country of Juqisan, which is now part of Silla, but for some reason a few decades ago, the small island of Yeongdo was a semi-autonomous territory.

At that time, this area, including the country of Juqisan, belonged to the Gaya Alliance.

Later in Silla's war to annex Gaya, the Gayak nobles fought to the death defending the last small territory of Yeongdo. Silla chose to negotiate peace, and some of the Gaya nobles became the inferior nobles of Silla, and some fled to Wajima.

The Gayyabara nobles, who became inferior nobles, had a small territory with partial autonomy.

This place was also called Shadow Island in later generations.

Silla has always wanted to solve this problem, and in the early stage, the contract was signed, so naturally it could not be torn up immediately, and in the later stage, because of the war with Goguryeo, there was no time to worry about these, not to mention

The country of Juqishan is one of the six strongest small states in the original Gaya Alliance.
