The timeline went back a month and a half ago, in late January 197, just after the Lantern Festival.

There is no way, who made the territory of the Han Dynasty too vast compared to the transportation technology of this era? Liu Bei occupied half of the vast western land from Xiliang to Jiaozhou in the north, and the distance from south to north was too far from south to north. When encountering emergencies in the Central Plains, the northern and southern territories could only respond randomly.

Lingnan, Nanhai County, Jiaozhou.

Li Su and Zhuge Liang and his party had been on vacation in Jingnan and Jiaozhou for almost a month or two. Zhuge Liang was the first time to see the real sea in the early twelfth lunar month of the previous year.

On the coldest days of the year, which should be the coldest of the year, you can enjoy a pleasant temperature that is almost twenty degrees close to thirty degrees every day, and you won’t feel cold even if you go swimming in the sea. It really makes Zhuge Liang, who has never been to the southern tropical in his life, feels that the quality of his life in the first 17 years is really poor.

The Zhuge family is already well-known in the world. The rich family ranked fourth in Liu Bei's camp has never enjoyed such a life.

In addition, everyone followed Li Su this time. With a luxury person like Li Su, the holiday conditions would be even better.

When he first arrived in Nanhai County, he spent money to collect slack farmers and used thousands of people to dig Taocheng on the beach south of Boluo County (Huizhou), transporting the silt and sewage and stones to the land reclamation farmland more than ten miles away, and trying to choose fine white sand to spread the resort beach several miles long.

The reason why Boluo County was chosen was because Li Su always knew that the sea water quality at the mouth of Dajiang River was not good, and the sea water at the mouth of Pearl River was turbid, so he could only set up docks around Panyu County (Guangzhou) and commercial industries such as shipyards, and not tourism.

In order to avoid the cold in winter, it would rather start a new job in Boluo, far away from Panyu. Just levying thousands of civilians to work for more than a month, each of whom required 600 yuan of corvee labor fees per month, Li Su paid out five million yuan out of his own pocket, so it was not considered corrupt.

As for Zhuge Liang's later expression of his desire to respect Master Li and help him pay the money, this is a later story.

After the beach is cleaned up, you must build wooden buildings and bamboo buildings for vacation dozens of feet off the shore, build some coconut trees, flowers and plants, and build a manor.

Zhuge Liang couldn't help but go into the sea to play before the beach construction was completed. Li Su grabbed him and told him not to be anxious. He also spent money to hire a fisherman to drive a pile of 50 meters off the shore and 200 meters wide from east to west. Then he used a large number of thick hemp fishing nets to cover the bottom to prevent sharks or other big fish and beasts from invading.

Li Su's life is very valuable. In the 21st century, he only swims in a beachfront with security measures, and he cannot save himself in the late Han Dynasty. However, Zhuge Liang felt that it was completely unnecessary - he covered a thick fishing net several hundred feet away in the sea. It would be better to send some excellent guards with good water properties to protect each time he went into the water to swim, and then sent a boat to follow him.

As Li Su, if he wants to go into the sea to swim and exercise, can’t he be able to hire a bodyguard in Ganning and Zhou Tai to guard him?

Since the beginning of the first lunar month, Li Su has been drinking coconuts beside Boluo Beach every day, under Shujin umbrellas, and leisurely with the sea breeze. Occasionally, when the sun is not strong, he goes to the sea to exercise for a while, and lives a very healthy life.

The girls he brought also took good care of his health with him, and then opened his eyes, purified his mind, and enhanced his practice. After all, Liu Miao and Zhou Ying had never seen the sea before.

Sometimes Li Su thought Zhou Ying and the others were not good at sunbathing clothes, so she drew a picture and asked Zhou Ying to cut and sew it by herself. Zhou Ying was a little embarrassed and felt that her husband's aesthetic was too bold.

But she also admitted that those things seemed to be more suitable for going into the water, so she did it secretly, taking advantage of the occasions where there were curtains next to her, and only Li Su saw them.

Don’t think so wrongly, Li Su didn’t do much shocking things. He knew the cultural acceptance level in the late Han Dynasty, so he only created something that was slightly more open than the cross-sling sling type dead warehouse, because the difference between that and the bellyband was not very big, and the bellyband was actually the bellyband above the chest.

Li Su would never induce girls to invent something despicable like Bimoni. He is a person with principles and limitations.

...

While enjoying the good and happy life, Li Su has not done any serious business in Jiaozhou these days. His purpose of public here was to bring Zhuge Liang to supervise Lusu's Nanhai Shipyard to benefit the ship, so this serious thing must not be lost.

Zhuge Liang was more self-conscious than Li Su. He enjoyed the beach holiday and ate coconut every day, which made him feel happy, so he went to the shipyard from time to time.

In addition, before their arrival, Zhuge Liang had actually sent an envoy in advance to send the "Fu Ship" and other miniature wood models he developed to Lusu. Therefore, the preliminary preparations for the Fu Ship started construction and started to be implemented one or two months before Li Su and Zhuge Liang arrived, and most of the required wood profiles were processed and prepared in advance.

Zhuge Liang only needs supervision in the final assembly and splicing process, and solve the new problems found during the trial production process, and there is not much work.

A few days after the Spring Festival, the first lucky ship from the Nanhai Shipyard officially went into the sea. Li Su also ended his vacation and went to the shipyard to inspect the new ship.

When Li Su came to the Nanhai Shipyard in Panyu, Zhuge Liang and Jiaozhou governor Lu Su were already there. They had a pretty speculative conversation recently.

This shipyard was originally built by Lusu organized civilian craftsmen in the first half of last year. The shipyard was built in the second half of the year and the materials were prepared, so it started to build a new ship, which didn't waste time.

Zhuge Liang was able to solve problems as soon as he came, so he naturally had a good impression of Lu Su, who was "assisted" and felt that this guy would work together easily.

When Lu Su saw Li Su, he sincerely praised: "Boya, what do you think of this new ship? The small size had already done a wave experiment before. I confirmed that there was no problem. I only magnified according to that structure to build it to twelve meters long. It was so magnificent.

I am also accustomed to living in the shore of the East China Sea for generations and have seen big ships. Back then, in Xuzhou, the coastal ship was at most five or six meters long. Later, the Mizizhong family's big sand ship was eight meters long, and I heard that Gu Yuansan was that the keel boat built by Li De'ang in Yongchang County could reach more than nine meters, but after all, it was not as good as ours now."

Li Su is of course familiar with the indicators of this lucky ship. After all, Zhuge Liang had already submitted the report when he designed it. Lu Su sighed at this moment, but when he finally saw the finished product, he couldn't help but exclaim.

The reason why this ship can be built larger is because the keel technology has been improved. Four years ago, in the Nujiang Basin of Yongchang County, in order to build a dual-purpose river and sea ship that can sail in the Nujiang and the Indian Ocean, Li Su pointed out Li Hui to introduce the "keel" structure.

However, the keels at that time were mainly "planar keels" in the sand ship system, which means that only keels are fully equipped at the bottom of the ship, and the ribs and dragon tendons on both sides of the ship were still relatively simple.

This time, because it has been made into a completely narrow and long pointed bottom suitable for breaking waves, the wet side and inclined bottom section below the waterline have also increased the pressure resistance of the water pressure. In order to ensure the durability and seaworthiness of the ship, the "three-dimensional keel" must naturally be designed to perfect the design.

This specific improvement work was tinkered by Zhuge Liang and Huang Yueying. Li Su himself was actually impatient to do such detailed mathematical calculations and force analysis. Zhuge Liang used Li Su's creativity to form a perfect and verifiable mathematical system.

Although it is not very accurate, so that there is more structural strength margin during construction, it is a huge improvement no matter what.

Throughout history, until the end of the Tang Dynasty, the sea ships of Eastern civilization only had flat keels on the bottom of the ship. The three-dimensional keels as tight as steel cages were not fully popularized in the late Southern Song Dynasty and even in the early Ming Dynasty.

So to summarize it in a brief sentence in words that even outsiders can understand, after Li Su and Zhuge Liang's seclusion, China's seaship technology was completely further advanced from the late Tang Dynasty to the level of the late Song Dynasty and the early Ming Dynasty.

The eight-zhang sand ship that Mi Zhu and Cao Cao are still using is only about twenty meters long when used, while Li Su, Zhuge Liang's ship can reach more than thirty meters, and it is also more seaworthy and faster.

"Then try it on the boat and going out to sea. I remember building several of the first batch, all of them can go out to sea, right?" Li Su inspected for a long time, and with great interest, he asked Lu Su to drive the boat out to take a look.

Lu Su: "I built three ships at once. Anyway, the ships are enough. I'm afraid that if one of them has something wrong with the test voyage, it will make people transfer to friendly ships. And I tried it with a small boat before, so this kind of bottom can sail freely in the Pearl River, and it may be very useful in the Yangtze River in the future."

Li Su: "It's useless to just say it. Let's try it out for a day when you go out for a voyage."

As he said that, Li Su ordered the most capable guards and sailors to go to the near sea to wander. All three ships were sent out, one of which could move alone and move away a little hard and make a lot of stress tests.

But there is no need for the ship that Li Su and Zhuge Liang personally ride, as well as the backup ship that escorted by him. At least he must make sure that if something happens, he can put down his boat and row back to the shore. He must not go out more than fifty miles to sea. Li Su is a pity for his life. Moreover, it is not auspicious to take a woman to the far sea.

Li Su also asked someone to bring fishing nets and poles that can be towed, just treat it as a leisure sea fishing day, don’t waste time.

After playing on the sea for a day, Li Su actually caught several South China Sea specialties Sumei fish and golden pomfrets, both of which were flat tropical fish. Li Su was familiar with the way to cook the chef on the boat.

It was also the first time Zhuge Liang went out to sea fishing on a boat. He was really excited. When he thought of riding on a big boat he designed, his sense of accomplishment became even stronger. Unfortunately, he is not good at qi cultivation and his temperament is a little impatient. He has gained less sea fishing than Li Su.

Li Su patted Zhuge Liang on the shoulder jokingly, and used a line that originally supposedly had been Zhuge Liang's education of his son Zhuge Zhan in history to educate Zhuge Liang himself:

"A Liang, when a gentleman is in a state of peace, to cultivate one's own self-cultivation, to cultivate virtue, to be indifferent to show one's ambition, to be quiet and to achieve far-reaching success. You are successful in your youth, brave and diligent, but sometimes you must be quiet and to endure the loneliness of "working for a long time but not yet seeing the harvest."

In the future, if you have time, you will drive a sea boat and fish for a day, and you will be able to beat your spirit. Since ancient times, those who have achieved great business will do their best to do their best. When you have finished your work, you will have to wait for the opportunity to come, and you will not be anxious."

After saying that, Li Su was as refreshed as the 21st Century keyboard warrior after he finished "Stand here and don't move and wait for me to buy oranges."

Zhuge Liang humbly accepted: "Mr. Li taught me that I have been a little bit... After doing things, no one is anxious and he is impatient. If you don't know it, you won't be angry. Isn't it a gentleman?"

The day after the sea fishing ended, he returned to Panyu County and left the boat to return home, Li Su noticed that Lu Su and others looked worried. It turned out that it was on the day Li Su went out to sea that some news came to the north.

"Boya, the general is dead. The news has been spreading to us for a month on the fifteenth day of the twelfth lunar month." Lu Su showed Li Su a letter that was not considered a report from the court.

This cannot be blamed for the news spread too slowly. The main reason is that Jingnan and Lingnan are indeed rugged and mountainous, and have miasma, which is not suitable for galloping horses to spread the message. On the other hand, it is also because Luoyang area and Jingnan are separated from the territory of the two princes of Yuan Shu and Liu Biao. These princes will not help Li Su to spread the message, and can only wait for the merchants who are doing business among the princes to naturally spread the news south.

Li Su thought for a while: "It has been a month since the general passed away, but there has been no news of unstable war. It is estimated that no one has taken action yet. If there is a war, the transmission of military information will definitely be much faster than this.

However, I should go back to Baqiu, Changsha to stand by. Zijing, what are the expensive military supplies in Jiaozhou that are easy to transport? I also tried to allocate a batch of water transportation, and go north from the Pearl River to the Xiangjiang River to the north, and maybe there will be war.

When the king implemented the reform of renting and transferring merits, he was staring at you except Yinchuan County. Jiaozhou was originally too remote and could not support the battle for the Central Plains battlefield. Now that there are sea ships, hurry up and build more.

As long as Sun Ce and Liu Biao have not turned against us, they will not intercept the Yangtze River as a thief, and the Fu fleet can transport Lingnan's products to the Yangtze River Basin at a low price. After all, Jiaozhou is a barren land. If you do this job well, the king will soon re-transfer you to the north and become a richer Jingzhou governor."

Lu Su: "Don't worry, if a Northern Expedition occurs, Jiaozhou will definitely support it with all its strength."

The next day, Li Su took Zhuge Liang, Zhao Yun and Wei Yan and other generals, and took a lucky boat and other inland boats to the Pearl River north.

The Fu Ship will definitely not be able to communicate with the ancient Lingqu canal between the Li River and the Xiang River, a tributary of the Pearl River, so Li Su and others had to change the boat when they arrived in Yulin County. But no matter what, this was also a stress test for the Fu Ship sailing in the inland river, which was regarded as a contribution to scientific research.

In the future, if there are sand boats in the Yellow Sea and Bohai Sea and the Yellow River, you can barely reach Sanhan. If there are blessed boats in the Yangtze River Pearl River Basin and the East China Sea, you may also be able to drive to Xiematai.

Li Su and his party rushed to test while rushing. After half a month, they slowly returned to Baqiu, Changsha County, and began to rectify their troops and mobilize supplies. A few days later, news of "Gui Ren Yuan and Gui Ren Cao being harmed by Dong Cheng" in the north followed one after another.

Li Su has such an IQ. When he heard the news, he knew that Yuan Shu would definitely be about to take action. So he also asked the navy from Jingnan to prepare first and go to Xiakou area in the lower reaches of the Yangtze River in advance. If he got the news of the war, he would immediately take advantage of the time difference in the south that was still in a peaceful state and insert it into the Han River Basin.

As for the army's troops, because the boundaries on the land are relatively clear, it is not suitable to invade Liu Biao's territory before formally attacking Yuan, which is not legitimate enough.
