The Xia army's successive movements in Burma and Annam completely detonated the fear of the southeastern countries, and the kingdoms of Nanzhang, Lanna, Ayutthaya, Cambodia and other kingdoms sent royal envoys to Jiangning to express their submission to the Xia Dynasty and beg for the protection of the imperial court.

Their worries and fears were actually superfluous, because the target of Su Yan's next move was not in the south, but on the other side of the sea, in the country known as the country of the rising sun.

That's right, it was the war against Japan.

At present, the western expeditionary army led by Li Laiheng, the Duke of Linguo, has set out from the city of Khante and headed westward, intending to pocket all the land east of the Ural Mountains of Tsarist Russia.

The shame of hundreds of years will eventually be washed away in this life, and Maozi's harm to Huaxia will also be eaten back on themselves under the command of Li Laiheng, and then it will be the turn of the country on that island.

If you want to go on an expedition to Japan, it is most appropriate to follow the route of the Yuan Dynasty hundreds of years ago, and to set out from the Han Dynasty, the fleet needs to cross the vast East China Sea.

Although there is also a typhoon problem from the southern part of Korea, this is the shortest route to sail, and the army can establish a forward port on Tsushima Island, and in the event of a typhoon, take temporary refuge in Tsushima Island before continuing the voyage.

Su Yan was a native of Fujian in his previous life, and he could hear the news of typhoons every year since he was a child, and the typhoons were generally concentrated in the second half of the year, that is, around July to November, and the typhoon holidays he was looking forward to often appeared during this time.

Therefore, he knew that he only needed to avoid the second half of the year, unless he was unlucky enough to encounter a typhoon that spawned in the first half of the year, and he generally only had to deal with the squalls and storms that were often seen during the voyage.

Compared to typhoons, these storms are just a small fight.

Having said that, the expedition to Japan was not just to wash away the shame caused by Japan in later generations, and the Iwami Silver Mountain, which is located on the island of Honshu and has the largest silver reserves in Asia, was also Su Yan's goal.

Silver is the circulating currency of the Xia Dynasty, which needs to consume a large amount of silver every year, and the domestic silver mines are completely insufficient to support large-scale mining, and Su Yan also has to consider leaving some resources for future generations.

Su Yan didn't have to think so much about the silver mines on the Japanese archipelago, he could mine with confidence, use the Japanese as coolies, hollow out the Iwami Silver Mountain, and all the silver mined into the country, or as military expenses to suppress the Japanese, and become bullets fired at them.

In addition to Iwami Ginzan, there is also the Sado Gold Mine, which was discovered in 1601 and was the most important source of gold for the Japanese government after mining began in 1603 and continued until the gold mines dried up in 1983.

Su Yan was a man of action, and after he had the idea of fighting against Japan, he immediately convened a cabinet meeting to explain his thoughts and decisions to the cabinet ministers, the heads of the two prefectures, and the heads of the six ministries.

It is worth mentioning that because Su Yan often held cabinet meetings that included the two governors and the six Shangshu, this had unconsciously become an unwritten rule.

Although there was no explicit stipulation, after the emperor ordered a cabinet meeting to be held in the Celebrant Supervisor, the Celebrant consciously informed the Cabinet, the Governor's Office, and the Six Ministries that these officials should attend on time.

If nothing else, after a hundred years of Su Yan, this tradition will also be continued and implemented by his successors.

After Su Yan told the ministers about his idea of preparing for an expedition to Japan, the ministers really exploded into a pot and began to talk about it.

Although Xu He, the first assistant of the cabinet, was used to Su Yan not talking to him in advance about anything, he was obviously taken aback, and he hurriedly said:

"Your Majesty, Japan is far away at the end of the East China Sea, thousands of miles away from our dynasty, and there is no reason to do it, and it has cost a lot of manpower and material resources to travel thousands of miles to conquer Japan, I am afraid that it is inappropriate."

"Yes, Your Majesty, although the Xianbeilian (the official name for Siberia in the Xia Dynasty, derived from the ancient legend of the birthplace of the Xianbei tribe) was very profitable, greatly increasing the revenue of the treasury, but it was not enough to support the provocation of many wars one after another, please think twice." household

Ma Guozhu, the secretary of the ministry, echoed.

"Please think again, Your Majesty." Zhang Kentang, an auxiliary minister of the cabinet, also echoed, and after he spoke, Wu Zhongluan, the secretary of the Ministry of Rites of the Zhoushan Party who was also with him, also followed suit.

There are those who oppose it, and naturally there are supporters, and the two governors of the two governors are natural supporters of the war, and Huang Enben, the governor of the navy, said:

"If Your Majesty decides to go on an expedition to Japan, and raise troops for a thousand days and use them for a while, my officers and men of the Great Xia Navy should swear to serve Your Majesty to the death and pave the way for Your Majesty to go on an expedition to Japan."

Metropolitan Governor Su Dingyuan also agreed.

"I'm the result of careful consideration." Su Yan said indifferently: "All Aiqing means that the conquest of Japan is not beneficial to the country, so I can tell you very clearly that Jinyiwei has spied on Japan that there is a silver mine and gold mine in its country that is richer than any known silver mine, and if Japan can be occupied, the silver and gold mines will naturally be able to be used by us, and the military expenses for the expedition to Japan will be solved."

As soon as he heard that there was such a rich silver mine in Japan, Ma Guozhu's eyes lit up, and he hurriedly said, "If there really is such a mine, then the minister will naturally support His Majesty's expedition to Japan."

Xu He nodded when he heard this, and did not continue to speak, but Zhang Huangyan, the secretary of the Ministry of War, raised his own question at this time, and he said:

"Your Majesty, if you want to go on an expedition to Japan, starting from Jiangning, the road is far away, and the sea is mysterious, if you encounter the obstruction of the storm, the navy is very likely to suffer heavy losses, hundreds of years ago, Da Yuan's several expeditions to Japan were all because of problems at sea, one of them landed by luck, but was still defeated by the Japanese army who was waiting for it."

"The minister does not want to oppose His Majesty's decision to conquer the day, but how to go on an expedition, where to start, and how many soldiers and horses need to be sent still needs to be considered in the long run."

Su Yan nodded, agreeing with his words, he said: "Where to go from, I already have an idea in my heart, at that time, although the Great Yuan conquered Japan several times, but there is no problem with its route, you can go from the south of Korea, with Tsushima Island as a transit point, and finally land on Honshu Island in Japan, my Great Xia Army is invincible in the world, as long as it is successfully landed, it is only a matter of time before it sweeps Japan."

"Starting from Korea, then the whole of Korea must need the help of the whole of Korea, so is the king of Korea willing to provide ports and food and grass for the army?" Zhang Huangyan asked.

"North Korea is just a vassal state of our country, do you still need to ask for their consent?" Su Yan asked rhetorically, and then he changed his words and said, "I want to follow the example of Dayuan and set up a province in Korea to conquer the east, so that the whole country of Korea can assist in the conquest of Japan, and build ships in the south of Korea to hoard grain and grass."

"In this way, I am afraid that there will be opposition from the dissatisfaction in North Korea." Wu Zhongluan, the secretary of the Ministry of Rites, frowned slightly and said.

"I have made up my mind about the conquest of the sun, and if there are Koreans who oppose it and try to obstruct it, I will kill them." Su Yan said murderously.

Immediately, he changed his words and said, "Intentions."

Guan Heiqiu, the middle scholar standing on the side, hurriedly picked up the pen and dipped it in ink, getting ready.

"In order to conquer Japan, he ordered the king of Joseon to place the conquest of the eastern province, to rejuvenate the army, to restore the post of governor of Joseon as the governor of Joseon Hou Sufu, and to govern the province together with the king of Joseon, and to kill anyone who obstructs the conquest of Japan, regardless of status."

Guan Heiqiu listened while brushing and recording Su Yan's dictation, and after the transcription was completed, he carefully held the holy decree for the emperor to see, Su Yan took a cursory look, nodded, and ordered someone to take the jade seal to seal.

Subsequently, Su Yan continued: "The matter of the conquest of Japan is very important, and it cannot be carried out in the short term, so it is necessary to make complete preparations, and the Naval Governor's Office will immediately dispatch the First and Second Fleets to the Korean Sanggyeong-do and Tsushima Island to station, and the Korean people can be requisitioned to build a water village, and the Armaments Department of the Governor's Office will work together with the household department to transport the materials, grain, and grass to the Gyeongju Mansion in Sanggyeong-do."

"The Governor's Office and the Ministry of War will discuss how many troops and horses should be recruited to expedition to Japan, and the plan will be presented to me within two days."

"Your Ministers obey." The ministers who were called said in unison.

After this cabinet meeting, the emperor's will was sent to Seoul, the capital of North Korea, and Su Fu, who received the will, said goodbye to himself and had just conceived

His wife, who was three months pregnant, took a personal salute and left Jingshi under the worried eyes of his wife and headed north.

After the emperor's decree was sent to Seoul, it immediately caused an uproar in Korea, and the Korean monarch Li Hao looked at the contents of the decree in amazement, he did not expect that the province that conquered the east hundreds of years ago would one day be crowned on the head of this country again.

However, as the most loyal vassal of the Xia Dynasty, Li Hao had no right to refuse at all, so he had to reluctantly accept this will and wait for the arrival of Su Fu, the governor of Joseon.

The establishment of the Eastern Province also spread quickly, following the footsteps of Korean merchants into Japan, and immediately reaching the ears of the shogun Tokugawa Ietsuna at this time, causing the entire Tokugawa shogunate to shake.

After more than 400 years, the Japanese once again felt the fear of their western neighbors, and Tokugawa Ietsuna hurriedly sent envoys to Gangning Castle under the pretext of paying tribute to spy on information, and at the same time, in order to gather troops on the western part of Kyushu and Honshu islands just in case.

Although the Tokugawa shogunate pursued a policy of seclusion and closed the country to the Japanese, it did not prohibit trade with the Dutch, Koreans, and Chinese, so it was not ignorant of its powerful neighbors to the West.

The strength of the Xia Dynasty made the Tokugawa shogunate tremble, and they thought that the Xia Dynasty would not attack them for no reason, but who would have thought that without any conscription, the founding emperor of the Xia Dynasty suddenly decided to go on an expedition to Japan.

This really frightened them.
