Ji Tang

Chapter 366: Your Majesty, please think twice!
After Ji Song came in, Li Shimin had been processing the memorial and pretended not to see him even salute him.

Chen Shou looked like he was looking at his nose with his eyes and his nose looking at his heart, which made Ji Song feel unspeakably depressed!

After coming here for a long time, Li Shimin stretched himself and stood up from the dragon chair.

Ji Song quickly greeted him with a smile on his face.

"You kid can't live in peace for a few days? I just made an agreement with Dugu Mou, and you beat him up and threw him to the ground?" Li Shimin looked at Ji Song with a look of hatred. what's good.

He knew that this kid was making excuses, but he had already been beaten, what else could he do?We can't beat him again!

"Bring something?"

Looking at the thick plate of paper in Ji Song's hand, he said.

Ji Songsheng handed the things over helplessly and said feebly: "Bring them here!".

Why are you asking for things? You are simply pursuing your dreams, but the situation is stronger than others. If you don't give it to yourself, you won't be safe at home.

If this continues, he is sure.

As long as he has a child, he will definitely "turn away from all relatives". There is nothing to say.

The emperor's move was so cruel that it directly caused chaos in his rear. He also acted as a good person and gained the gratitude of Ji's mother, You Ning and Ji.

Ji Song's teeth were itching, but there was nothing he could do. They were using conspiracy, using You Ning's thoughts to achieve their goals openly, and they even said it was for your own good.

Therefore, after finding out at home, Ji Song has basically lost the opportunity to go to sea, and will be strictly guarded from now on. After all, when he wrote this thing, it was no longer necessary for him.

He has thought clearly in the past few days. Since it is unavoidable, he will try to write down the risks and references he may encounter along the way in more detail.

According to his idea, he started from the coast of Dengzhou in the Tang Dynasty and went north along the coastline, bypassing the Liaodong Peninsula and the Korean Peninsula.

It passes through the strait between the Japanese country and the mainland, all the way to the Bailing Strait, enters North America, and then continues southward along the coastline until it reaches South America.

Only when you get there can you find what you want.

Li Shimin didn't care what Ji Song was thinking, as long as he achieved his goal, everything else was irrelevant.

He carefully looked at what Ji Song had written, and found that there were ways to deal with situations that might be encountered at sea.

He looked at it and saw that there were hundreds of them. He didn't know how this kid knew about them?
"Is there any basis for what you said?"

Li Shimin was really asked clearly. He just took a look and found that according to Ji Song's route, there were tens of thousands of miles along the way. Such a long journey, at the current speed, would take at least several years to go back and forth.

He must ensure the accuracy of these information, otherwise, this is not exploration, but a waste of human life.

Ji Song also understood what Li Shimin was thinking and said directly: "In fact, there is a precedent for crossing the sea in the pre-Qin period. Technically, our Central Plains is not bad at all."

"But many of them were damaged or lost in the long river of history. During the Qin and Han Dynasties, we have begun to consciously use the ocean wind direction for navigation."

"The ancestors have mastered the monsoon laws of the East China Sea and the South China Sea, and have applied them to navigation activities."

"In fact, Yingxun of the Eastern Han Dynasty mentioned in "Customs and Customs" that 'there is a plum blossom wind in May, and Jianghuai is considered a trade wind.'

"The 'Luomei Feng' here means the southeast trade wind that appears after the plum rain season. These are consistent with the monsoons mentioned by those maritime merchants. It's just a pity." Ji Song shook his head and stopped talking.

Li Shimin knew why Ji Song didn't say anything. These were all caused by wars, especially during the Three Kingdoms at the end of the Han Dynasty and the Five Husties in China, when many precious materials were lost.

This was due to his Xianbei ancestors, so he just coughed and nodded without changing his expression.

In fact, he also knew that there were records of these in history books, but many of them were in the hands of aristocratic families, and it was impossible for him to get them.

Ji Song knew this because he had been poaching the aristocratic family over the years, and thus got a lot of books that they considered miscellaneous or useless.

In the pre-Qin period, based on celestial navigation, the positioning technology in the Qin and Han dynasties was further improved.According to "Hanshu Yiwenzhi", the astrology of maritime navigation in the Western Han Dynasty included 22 volumes of "Star Divination in the Sea", 130 volumes of "Miscellaneous Matters of the Five Stars in the Sea" and other related books, totaling [-] six volumes.

It may be the astronomical experience and rules summarized by the people who went to sea in the Central Plains during their voyages.The content should be to record the position determination of constellations, planets, etc. during navigation to confirm the route.

In addition to celestial navigation, celestial navigation and land positioning also play a very important role in navigation.

During the Han Dynasty, the Han people's understanding of tides was no longer limited to the rise and fall of the water surface, but could also find out the causes.

Wang Chong systematically connected the causes of tides with the movement of the moon for the first time in "Lunheng·Shuxu Chapter". At the same time, it was of certain help to navigation on the sea and using the tide direction to enter and exit the harbor.

In short, the shipbuilding industry was developed during the Qin and Han Dynasties, and it was able to use monsoon navigation, astronomical and geographical positioning, and geometric theory to further improve, and to make systematic and reasonable explanations of tidal phenomena. The advancement of navigation technology made the Central Plains Dynasty at that time Get on the fast track to sailing at sea.

However, things are unpredictable, and continuous turmoil completely disrupted this trend, and people started a new round of exploration again.

When the former Sui Dynasty traveled to Liaodong, it was because there were no people familiar with sea navigation that most of them were damaged in a storm.

Destruction is always faster than construction. After hundreds of thousands of years of accumulation, everything was lost in just a few catastrophes, leaving only a few words on decaying bamboo slips.

Ji Song came back to his senses and looked at Li Shimin with a somewhat complicated look. He said, "It's not that I have to go, but this time is of great significance. I want to ensure that this voyage has the greatest possible success."

"You also know that neither sea vessels nor qualified personnel can be obtained in a short time. Huge expenses and hard-to-find talents."

"These are just the basics, and we have no idea whether it will bring us the expected benefits."

"Once you fail, Your Majesty, tell me, do you still have the courage to try again?"

Li Shimin was stunned. He didn't expect Ji Song to say that?

Yes!

If it fails, or none of these people come back, is it possible for me to spend a lot of manpower and material resources again for an illusory thing?
Ji Song continued: "In the Tang Dynasty, no one is more suitable than the boy. This is why I have the courage to choose anyone else in this matter."

"Your Majesty! We cannot afford to fail. As long as we fail once, it will be too difficult to try again in the future."

"From now on, this incident will be a deed for future generations to remonstrate with the emperor, and it will also be a stumbling block that prevents the people of the Tang Dynasty from going to sea."

He bowed deeply to Li Shimin and wanted to make a final struggle.

"Please, Your Majesty, think twice!"
