It is not difficult to defeat Gongsun Kang, who had just inherited his father's business but was not yet on his anniversary. Compared with Gongsun Kang's military power, the gap is at least dozens of times.

Of course, in fact, considering the transportation capacity and logistics constraints of cross-sea operations, Dahan's ability to invest in the Sanhan battlefield will definitely be less than one-tenth of the overall combat power of Dahan.

After Liu Bei unified the Han Dynasty, after the first two and a half years of rest and stability, the military demand had been greatly reduced. He temporarily eliminated some troops and sent them back to farmers. The total force that could be recruited and invested in combat was reduced to about 500,000.

Most of these 500,000 people also entered peaceful military camps. They trained for a few months every year, which was about the same time as the people's labor service, and they only occupied slack farming in winter and summer. During the busy farming season, all farming was self-sufficient.

For this part of the troops, the benefits they can get from being a soldier in peace are simply that they no longer have to pay taxes, land and rent to the state or to do labor service. All the income from production and labor can belong to individuals

(Note: In fact, some officers gradually transformed into landlords. They would ask the soldiers below to take a little bit of filial piety. The exploiting troops drink blood from soldiers must not be completely eliminated in ancient troops. However, the dynasty had just revived, and this problem was still very minor, and the soldiers could bear it completely, and they didn't feel anything for the time being.)

There were at least 300,000 soldiers transferred to the military camp, so the final standing army was only 200,000.

These 200,000 people need to bear the deterrence of the grassland people and the barbarians in all directions, and they also have to be responsible for internal security patrols, suppressing bandits and suppressing rebellions, and intimidating unjust officials. They can no longer be reduced.

The military rations that this group of people had to be fed from the official grain collected by the state, and additional military pay was also given. Each person consumed twenty stones of grain, three thousand coins of copper coins each year, as well as several weapons and consumables, and military supplies such as tents.

So in the tenth year of Zhangwu, the expenses of the imperial court to raise soldiers in one year were about 4 million stones of military rations, 600 million copper coins and military pay, 400 million copper coins and military supplies, and depreciation.

In addition, because the taxes in Kanto area were exempted for two years and other areas were exempted for at least one year, now the people have some surplus food, and there has never been a large-scale starvation of famine.

As a result, the price of grain generally decreased, and the court did not have the problem of paying extra high prices to buy grain and raise soldiers. After all, the total expenditure for soldiers a year was controlled at about 2 billion yuan.

In the years when the War of Unification was the most intense, especially when it was the decisive battle with Yuan Shao and Cao Cao, Liu Bei's military expenditure was all aimed at a New Year's Eve battle, and the entire army spent a total of 15 billion yuan.

Therefore, the current military expenditure has been reduced to less than one-seventh of the strategic decisive battle.

The savings of 123 billion yuan per year can offset the average annual issuance of nearly 10 billion yuan of cited national debts during the war, and the balance of 200 billion yuan can be paid to repay the principal and interest, and repay the previous national debts.

Once his position is different, his position of considering the problem will certainly change accordingly. Liu Bei's current mentality is that all the great man belongs to him, and of course he cannot be ruined or destroyed anywhere.

A guy who buys zero yuan will smash the things in the store, but the store owner will not protect his store.

By extension, when Liu Bei's court now considers military issues, it no longer "just win" but also takes into account "how to save money to win".

Fiscal surplus can easily enter the debt repayment cycle, which is addictive.

If you don’t fight, you will save 12 billion yuan a year. Who doesn’t want to?

Previously, the imperial court had accumulated a total of 50 billion yuan in debt, and the interest included could reach 70 to 80 billion yuan. Later, it was difficult to rely on some top nobles to reduce their debts and exchange bonds for permanent tax exemption for the animal husbandry and iron smelting industries, reducing the total debt by about half.

The remaining 35 billion to 40 billion will have to be paid back by more than ten years. Even if the Kanto region resumes production and increases industrial production capacity with Pan Technology, the total tax source energy will increase by more than 30%, which will not only shorten the debt repayment time by 40%.

In summary, if the Liu Bei government does not launch any war or engage in any infrastructure projects such as the Grand Canal, it will not be able to pay off the debts from around 211 to 212. This year it has paid off the first year, and there will be seven years in the following year, with a total debt period of up to eight years.

In this case, Liu Bei's request for Li Su to eliminate Gongsun Du was far from winning. He also asked him to spend less money and get rid of the problem by using less troops to cross the sea. That was the best.

...

On the tenth day of May, Luoyang.

It was five days ago that Liu Bei received the first report on the changes in the Sanhan area from Zhuge Liang who was in Qingzhou.

Of course, Liu Bei received the report, which means that in Qingxu, Taishi Ci had already started the war dispatching and raising work. After all, Luoyang is so far away from the shore of the East China Sea.

Liu Bei was not very anxious about this opportunity. He believed that Li Su could handle the front-line troops of Qing, Xu and Yang well, and dispatch and organize the offensive by themselves to solve the problem.

So Liu Bei just chatted with Xun You and Lu Su about this information and asked about their opinions, and then did not take the information to the court meeting for a gathering.

A prince died in the barbarian land and father and son passed the throne. This was just a natural event, and it did not mean that there would be military actions immediately. It was not worthy of being taken to the Han Dynasty for solemn discussion.

So, five days later, on the tenth day of the 10th day of the lunar calendar, Li Su's memorial arrived in Luoyang one after another after Zhuge Liang's information.

At first, Liu Bei thought it was a report on the preparations before going to the battle, but after meeting with Zhang Song, the messenger sent by Li Su, Liu Bei found that it was not that simple. Li Su actually asked Liu Bei to mobilize reinforcements from another direction to attack the battlefield of the Three Koreans.

This surprised Liu Bei. For the first time, he felt that the Prime Minister was too cautious. It was just that Gongsun Du was left with Gongsun Kang after his death! The Han army in Qing Xu Yang’s three prefectures could not handle it? Now the Han Dynasty not only had to win battles, but also saved money to win battles!

Liu Bei's strategic thinking tendencies are completely opposite to those of Emperor Yang Guang of Sui in history.

When Yang Guang dealt with Goguryeo, he wanted to pile up 1.17 million troops. The logistics pressure was overwhelming. He transported grain and repaired rivers to requisition more than two million civilians. The dead grain transported grain and bribers were able to catch up with the Goguryeo army.

Liu Bei wanted to not interrupt the pace of rest and recuperation. If he could handle 70,000 or 80,000 people, it would be better if he could handle 70,000 or 80,000.

Fortunately, Zhang Song was quite eloquent and knew the secret. He explained Li Su’s preliminary idea to the emperor in detail, and then pointed out that the prime minister didn’t need much money:

"...Your Majesty, the Prime Minister's purpose is to try to spend as little military resources as possible, so he solved the problem. Because of this, he needed General Cavalry to lead thousands of cavalry to go south from Lelang County and patrol along the Han River to intimidate Gongsun Kang.

The food routes of the thousands of people of General Cavalry can be maintained by sea, and there is no need to go deep into the hinterland of the belt. Just move south along the west coast of the Sanhan Peninsula. There are coastal and waterways available, so General Cavalry's logistics costs will not be too high.

As long as you attract all Gongsun Kang's main forces to the south bank of the Han River and beware of General Cavalry crossing the river, General Taishi and General Gan will naturally cut off Gongsun Kang's retreat with less force."

Liu Bei also came back to the point, and he knew that Li Su did not increase the total cost of military use.

Moreover, as the prime minister, Li Su, although he was in charge of all officials, did not have the power to directly dispatch Zhao Yun, who was currently temporarily stationed in Liaodong. Asking for the emperor to come forward to dispatch is also a safeguard for the court's constitution.

On the other hand, Liu Bei guessed that Li Su was also avoiding suspicion and did not want only his men to appear in Sanhan thousands of miles away.

After all, remote areas should be wary of separatism. There are two top civil and military officials of the imperial court that are not subordinate to each other. Each leads some troops to enter the newly conquered areas. This will also lead to a nominal supervision and restraint between each other.

So, in fact, Zhao Yun’s people don’t need to fight any war at all. Zhao Yun just showed his face to attract the attention of the enemy, and at the same time, it would be easier to witness during the subsequent occupation.

"Even so, the Prime Minister asked for instructions so repeatedly, aren't he afraid of delaying the fighter plane?" Liu Bei felt that Li Su had said, but he was a little regretful, afraid of missing the best offensive node.

Fortunately, Zhang Song also explained in detail: Li Su and Zhuge Liang both speculated that Gongsun Du had been dead for a while, and Gongsun Kang should have been in charge of the acquisition of Quan, so it is not a shortage of two or three months.

The Prime Minister had no intention of using troops in the midsummer and hot summer, but had to delay until the initial end of the autumn harvest, so he slowly prepared for instructions and asked for instructions.

"That's good. I will give Zilong the will, and it's enough to ask him to bring three or five thousand cavalry." Liu Bei finally made the decision.

...

From Yangzhou to Luoyang, the imperial envoys had to travel for more than ten days without any quick horses than those post offices. And it would take more than one month to go from Luoyang to Liaodong.

With thousands of miles apart, the whole process was completed and prepared, but at least more than three months had passed.

Li Su, Zhuge Liang made preparations in April and went to Zhao Yun to prepare for the troops. It was already half past July. According to the harvest celebration of the Zhongyuan Festival on July 15, it was not the autumn harvest.

During this preparation period, generals such as Taishi Ci and Gan Ning did not know the specific layout of the prime minister at the beginning. Li Su and Zhuge Liang were planning to do the overall strategy, and the generals were only responsible for the specific leadership of the troops.

In early July, Li Su felt that the time was right, so he considered his overall plan, taking into account the strategy of "how to prevent Gongsun Kang from continuing to escape after being defeated", and gave a thorough explanation to the main generals:

"The three Han Gongsun Kang, who has always prepared more than 40,000 to 50,000 soldiers. If the three Hans and Fuyu troops are combined, they will force militia to join the army during the war, the total number will be estimated to be 150,000. However, the extra 100,000, that is, the mob and the subordinates of the auxiliary soldiers are not afraid of except for siege.

This time, our army plans to divide the troops into two groups, Ziyi and Xingba, and you will lead 30,000 troops across the sea.

Ziyi landed from Donglai to the south of the Belt and Road. After arriving, he unloaded his soldiers and divided some ships along the coast of Lelang to the Belt and transported grain from Lelang to the front of the army, and maintained the needs of the cavalry of the main unit and the Zhao cavalry.

If you dare to fight in the field, you will destroy it. If you encounter Gongsun Kang defending the city to the death, you will surround it without attacking it. There is no need to waste your lives with those mobs.

The key to this tactic is Xingba along the way. Xingba, you will take Gongjin as your guide and set sail from the Kuaiji Yongdong Islands to the east. The fleet will bring enough additional training navigators and drive to the east.

You can find several small islands belonging to the Liuqiu Islands according to the chart provided by Gongjin, and then navigate with a compass, and position them according to the chart and star track, so you can reach the bear martyr south of Xiematai.

Go north along the island, you can go to Xiematai and cut off the Typhoon Strait. The purpose of this journey is not to kill the enemy, but to cut off the retreat of Gongsun Kang after his defeat and continue to flee east! Close him and kill him in the land of the Three Hans so that it will not spread!"

When Taishici and Gan Ning heard it at first, they felt that Li Su's strategy was a bit too radical.

Of course, it is not impossible to combine with the current navigation and navigation technology of the Han Dynasty.

If it was a year and a half ago, the Han navy was allowed to travel eastward and pass through the sparse islands of Liuqiu Island, it would definitely not be daring to do so. If the navigation technology was not up to standard, it would be easy to miss the island, pass it between the islands, and then go all the way to the Pacific Ocean, which would easily lead to starvation and thirst on the sea.

However, during the farming preparation period for the past year and a half, Li Su did not let Zhou Yu's pawn be idle.

Since he learned that Zhou Yu had learned the island-hunting techniques of the Polynesian South Island people, Li Su has been training a large number of navigators in Ganning's navy. After nearly twenty months of training, there were hundreds of Han sailors who had initially mastered the island-hunting techniques of the Polynesian exploration island-hunting techniques.

These people are now considered senior talents. After they have finished their studies, the imperial court will give each salary of at least hundreds of thousands of yuan per year, and hundreds of acres of tax-free land.

With talent and equipment guarantee, Li Su is not worried about the low-level mistake of "when he arrives at the first island chain, he passes through the island chain and misses the island."

At this time, the difficulty of direct flights from Kuaiji to Sanhan and direct flights from Japan is actually no different. As long as you avoid the typhoon season, wind and waves, and hydrology are actually the same.

The reason why the ancients could not travel directly to Japan was that the technical shortcomings were in navigation, not ship hardware.

Historically, the Japanese sent the Sui envoys and the Tang envoys in the early days, basically took the shore route, first to Sanhan and then to Donglai and then landed. Only in the middle and late Tang Dynasty did Japan learn to land along the Liuqiu Island chain to Mingzhou.

Because of this, Li Su is now using a navigation technique that has been ahead of at least four or five hundred years. It would be impossible for Gongsun Kang to think of it, and he would not be wary of Gan Ning appearing directly from behind and cutting off his retreat.

Because in Gongsun Kang's mind, if you want to get to Xiematai, you can only go to Sanhan first, then to Talent, and then to Xiematai. There is no second way. This is a linear journey of a one-man guarding the pass.

Therefore, as long as Gan Ning appears from behind Gongsun Kang, it will be a dimensional reduction attack.

From the two-dimensional plane world to hit the one-dimensional linear world, Gongsun Kang thought that as long as he kept a line, the laws of nature could be circulated.

This is another advantage brought by the crushing of technology and cognition. How can Gongsun Kang stop it?
