Li Ke once thought that ancient Chinese sailing ships could not sail against the wind, but after careful communication with Yu Wenlin, he learned that the ancient Chinese hard sail was actually far smarter than Li Ke thought, and the hard sail could also sail against the wind, but its utilization rate for the headwind was slightly lower, and the angle that could be changed was smaller.

Obviously, the ancients were far smarter than Li Ke thought, and now Li Ke gave Yu Wenlin's books, so that his improvement of sails is almost the same as that of sail ships in the nineteenth century, including but not limited to the use of horizontal sails, but the materials of sails can not keep up, but this is not Yu Wenlin's problem, this needs to be improved by the weaving industry.

"Your Highness, if you do this again, there will be no one to help me." As soon as the fleet sailed on the sea, Sun Simiao came over with a helpless face.

Speaking of which, Sun Simiao is not what Li Ke wants to take, it is Lao Sun himself who wants to follow, he said that he has not had a chance to go overseas to find medicinal materials, so he has to keep up, and Lao Sun also brought a team of dozens of people.

After these dozens of people came to Chang'an, the Langzhong brought out during this period of time, they were not exactly brought by Sun Simiao, and they were also trained by Yuelai Commercial Bank before.

"It's not that I don't think there may be enough doctors in the shipyard here, so I left three for them, and there are not many people." Li Ke said. "By the way, those death row inmates are fine."

"I don't see any problems at the moment, but are you sure that the theory of this food is normal, Your Highness?" Sun Simiao looked at Li Kedao with some suspicion.

"Of course, let me tell you, if you only eat meat and pickled fish, in the long run, you will have this kind of scurvy." Li Ke said with a serious face, "I don't believe you will know with us this time, anyway, I mobilized five death row prisoners for you to experiment, and they all eat the same food, and you will know after two or three months." ”

"Okay." Sun Simiao nodded, but did not refuse, anyway, these death row prisoners are all punished for their crimes, Sun Simiao has no psychological pressure, he is almost a hundred years old, there is no so-called moral pressure in this regard.

Speaking of which, Li Ke also knew for the first time that Sun Simiao had actually dissected the human body in this era, and he secretly dissected it himself, after all, in this era, no family member would let you do this, even if you were Sun Simiao.

Obviously, Lao Sun has a lot of fun on the road of medical research than Li Ke.

Li Ke's reproduction of Sun Simiao is naturally a study of scurvy, and it can't be said to be a study, in fact, it's just a lack of vitamin C, but in fact, it doesn't have much significance for the current Datang, because with the continuous popularization of potatoes, as long as potatoes are added to marine food in the future, there will be no such thing.

Potatoes are the only food that people can't die of eating just by eating it, and they don't lack nutrients, nothing else. Of course, it is definitely not good to live, but compared to other foods that can cause problems after eating only one for a few months, potatoes are already an unprecedented awesome food.

Today's wind and waves are a little big, Changle, who originally had no problems along the way, Li Yan and the others were a little uncomfortable, after all, the wind and waves suffered by the ships on the ocean and inland rivers were not at the same level at all, but Sun Simiao was too awesome, more than ninety years old, and he was not uncomfortable at all.

Li Ke who watched it was envious, let alone ninety, he was eighty years old to have this body, thank God.

But I don't know if it's a problem with exercising over the years, Li Ke doesn't get seasick at all, although seasickness actually has little to do with exercise, this thing is mainly a problem with people's brains.

The fleet headed south, and after arriving near Hudu, the already loaded fleet quickly joined the ranks, while the empty ships that followed from the Bohai Sea stayed here and continued to load supplies.

The fleet, which had expanded to more than twenty ships, quickly moved south, and about 8 days later, the fleet arrived at the periphery of the port of Guangzhou!

This speed made Li Ke nod with satisfaction, the speed of the ship after adopting modern sails is indeed much faster than this era, of course, the low resistance of the pointed bottom boat is also one of the biggest reasons.

And Li Ke's arrival is naturally a big event for the Guangzhou Mansion, especially when the Qinwang with the Tang Dynasty flag erected entered the port, everyone on the entire dock was stunned, when had they ever seen such a huge ship, and what shocked them even more was that the bottom of this ship seemed to be made of steel! And the front of the ship also has a steel ramming angle!

Under the dock, the senior officials of Datang Lingnan Road are actually here, Li Ke squinted his eyes slightly, these people ...... It's not easy.

Lingnan Road is different from other roads, Lingnan can be said to be poor mountains and bad waters since ancient times, and the family reputation that has been passed down here from ancient times to the present is not obvious, unlike other gate valve families in the Tang Dynasty, but in fact, Lingnan Road has its own local wealthy families.

The annexation of Lingnan Road to the Tang Dynasty was resolved peacefully, and most of the wealthy clans here in the late Sui and early Tang dynasties were aware of their strength and surrendered one after another. There is one person who has the greatest credit, and this is the current governor of Gaozhou, Feng Anang, the Duke of Gengguo of the Tang Dynasty.

Feng Angqi was a famous general during the Sui Dynasty, and he once followed Yang Guang to lead an army of one million to the north to conquer Goguryeo, so he had seen the world, and it was precisely because of this that he knew very well that his thirty or forty thousand horses in Lingnan were drizzle compared to the Central Plains army, so during the Wude period, Feng Ang surrendered.

Subsequently, Li Ke's grandfather Li Yuan rewarded Feng Ang several times, divided Lingnan Province into nine prefectures, and appointed local wealthy families as governors to control Lingnan Road.

These nine prefectures are Guangfu, Xunfu, Nankangfu, Gaofu, Guifu, Nanyinfu, Qinfu, Jiaofu, and Nande Fu, corresponding to the eight major forces, as well as the first important town in Lingnan and the port of Guangzhou.

Among them, Guangzhou Prefecture is directly managed by Datang, and the remaining eight prefectures are local wealthy families, such as Li Xizhi Guizhou Governor, Qiu and Jiaozhou Governor, Li Hui Nandezhou Governor, Li Guangdu Nanyi Prefecture Governor, etc.

For example, Li Xianzhi was also born in the Li family of Longxi, and his fifth ancestor took refuge and migrated, and after Xiao Mian Xian was eliminated by the Tang Dynasty at the end of the Sui Dynasty, it was Li Xianzhi who encouraged more than 60 states in Lingnan to return to the Tang Dynasty.

And today the eight local forces and others have already come, including the Guangzhou Governor Dang Renhong.

Getting off the boat, Li Ke had already changed into his royal clothes, and Changle was naturally followed by him, followed by Li Yan and Wu Jue, while Yang Anning and others did not get off the boat.

"The ministers have seen His Royal Highness the King of Qin, His Royal Highness Changle." The governors in the front row saluted Li Ke and Changle one after another.

Li Ke has never seen any of these people, Guangzhou is really far away from the emperor, and it will take at least a few months to go to Chang'an to report on his work, so many times the officials here may not return to Chang'an for several years.

And Dang Renhong has just moved to the governor of Guangzhou.
