After singing the song "Will Enter the Wine", almost everyone present remembered it.

"Third brother, it turns out that 'life must be happy, don't make the gold bottle empty to the moon!' I am born to be useful, and my daughter will come back when I am gone, don't worry about the road ahead without a confidant, and no one in the world knows you. Others laugh at me for being crazy, and I laugh at others for not being able to see through it. 'Isn't it a poem?' Changle asked with a strange expression.

"Well, no, no, it's several, I wrote it casually." Li Ke waved his hand, he had forgotten when he read these things that Changle had read, it seemed to be the previous time in the court, right?

Fortunately, when I stitched the monster by myself, I didn't "hang the southeast branch".

Changle and Li Yan were a little speechless, they had never seen this kind of poem that only recited one or two sentences.

"Third brother, Master Cen, who is Dan Qiusheng?" Changle asked again.

"I don't know, you don't care who it is, just let me copy it." Li Ke waved his hand.

Everyone was a little speechless, obviously Li Ke didn't want to say it, but it didn't matter if he didn't want to say it, this kind of code name, anyone could possibly, but I didn't know that this was a poem written by the third brother when he was drinking with someone, so wild, but it was quite in line with the third brother's state of mind.

The barbecue on the deck soon fell into the curtain, but the ship continued to move forward, and by the evening it was estimated that it would be able to merge into the Yellow River.

Li Ke's itinerary is very simple, after entering the Yellow River, they will go down the Yellow River and go straight to the mouth of the Yellow River.

Figure: Chart of the Yellow River in the Tang Dynasty and later generations.

The time on the road is relatively long, but because it is downstream, and the weather is good recently, and there is just the moon at night, so the ships at night can also travel, with the current speed of the ship with the speed of the ship downstream, you can travel nearly 600 miles a day, and you can reach the Bohai Sea in about four days.

The reason why Li Ke and they want to go to the Bohai Sea, instead of transferring from the canal to the Yangtze River, is because Yuwenlin has built a brand new flagship for Li Ke, and it has just completed the sea trial test, this time Li Ke went to receive it directly, and the other fleets are loading ships near the mouth of the Yangtze River.

Four days passed quickly, Li Ke and they also arrived at the Bohai Sea, when leaving the Yellow River, Li Ke and all of them stood on the deck and looked at the sea and sky in front of them, as well as the blue sea.

Changle and those who have never seen the sea are shocked by the vastness of the sea, while Li Ke is shocked by the blue water, it turns out that the Bohai Sea is not always yellow.

In fact, the current Yellow River is not very yellow, but the water quality of the Yellow River has begun to turn yellow, because the trees on the Loess Plateau have been gradually cut down by people, and they have been destroyed to a certain extent in the Tang Dynasty, and the Zhenguan period is still fine.

But with the passage of time, with the increasing population of the Tang Dynasty, the Loess Plateau is still where a large number of trees will be cut down.

Li Ke pondered for a while, should he implement the afforestation plan from this time? Because it's too late to save now.

If Li Ke only needs to contribute one part to save now, then if the current situation is maintained more than a thousand years later, I am afraid that it will not be possible to exert a hundred points of effort, and it will take a thousand times to save it.

Although the current Loess Plateau is said to be seriously cut down, but soil erosion is not completed in a few years, but a long process, and now the climate in these places is not so bad, if you start planting trees at this time, the precipitation here is not bad, and the trees will soon survive.

So it's easy to stabilize, and it won't take too long, and in another one or two hundred years, I'm afraid it won't be so easy to control.

Hey, "Twenty-Two" evolves! Article 23.

In fact, there is no shortage of arable land in the current Tang Dynasty, because of the continuous wars, from the end of the Han Dynasty to the present, the entire Central Plains region has not had much time to recuperate, and the population is very small, so a lot of arable land in these places on the Loess Plateau has not been planted.

Even after the stabilization of Datang, the population began to increase dramatically, but Li Ke felt that the land area of Datang would increase rapidly in the future, and Li Ke would definitely migrate.

As for how to immigrate, it is not difficult, as long as the corresponding policies are given, you have to believe that the people have been thirsting for arable land and a better life since ancient times.

Therefore, for many years in the future, the population of Datang will always be in a state of shortage, and there is no need to worry about the lack of arable land, not to mention that the Loess Plateau itself is not strictly speaking, not very suitable for farming, but because it is closer to Chang'an, the population gathered is relatively large.

In fact, the future economic center of Datang can be transferred to the east, after all, what does Chang'an say? In fact, it is not very suitable to be the capital.

Changle and the others were chattering and discussing there, and the person in charge of controlling the ship had quickly joined the pilot ship waiting at the mouth of the sea, and then sailed to the dockyard.

It is located in the sea near Laizhou City, Weifang.

In fact, the urban area of Weifang in later generations is basically the ocean now, because the marine coastline in this area is much deeper than that in later generations. As for why the coastline was pushed back so much in later generations, it has to be said that the Yellow River, a river that has flowed for thousands of years, has naturally cast how much land has been cast.

Every year, a large amount of sediment on the Loess Plateau is flowing into here, and it is diverted several times near the mouth of the sea, and several times during the Song Dynasty and the Ming and Qing dynasties, all because of the large amount of sediment accumulation here.

While Li Yan was discussing with Changle and them, she looked at His Highness who was quiet next to her, she knew that His Highness must be thinking about things again, maybe he was thinking about the national policy of the Tang Dynasty again.

Hey, Your Highness is really a worried person.

It took more than half a day for the fleet to come to the vicinity of the port, and when they arrived, a huge ship outside the port appeared in everyone's sight, if Li Ke's current 1200-ton ship is a giant in the eyes of Changle and them, the ship in front of them is even bigger!

After getting off the boat, the workers who had been waiting at the dock quickly began to carry the goods, while Li Ke went to see Yu Wenlin.

"Your Highness." Yu Wenlin's whole mental state is excellent, giving people a feeling of shine.

"How?" Li Ke asked with a smile.

"Your Highness is unprecedentedly good, the minister thinks that in another five years, the minister can advance the volume of the sailboat to 3,000 tons of displacement!" Yu Wenlin said seriously.

"How big is that big guy out there?" Li Ke was a little curious.
