In the city of Wei State, Zhao Jie, who had been waiting for five or six days, finally waited for Zhao Sheng, the king of the plains who returned to the east.

"Your Highness's plan to get rid of the golden silkworm is really exquisite, if it weren't for His Highness's letter, I wouldn't have found any flaws in it." Pingyuanjun exclaimed: "I wasted a few tears in vain." ”

Zhao Jie involuntarily touched his head when he heard this, and said with a smile: "I also had a whim, don't praise me anymore, the smooth implementation of this plan is mainly due to my brothers!" ”

"Your Highness is humble!" Pingyuan Jun Zhao Sheng continued to ask with a smile on his face, "Where is Your Highness going in the future?" ”

"I decided to go north to Yanmen County and join the army to experience and train." Zhao Jie's face suddenly changed, and he said with a straight face: "By the way, I will familiarize myself with the military system and current situation and equipment of my Zhao State, and understand how the war is fought today, how it is carried out, and how it ends." ”

"Yes, Your Highness's concerns are good!" Zhao Sheng, the king of the plains, said earnestly: "As a king, you can't know the soldiers, Your Highness is now experiencing it personally, which is the blessing of my Zhao country." ”

"Your Excellency really thinks of me." Zhao Jie said modestly. Before the words fell, Zhao Jie immediately continued to order: "Your Majesty, please don't tell anyone about my golden silkworm shelling, so as not to cause an uproar." “

"Of course, Lone has always understood the stakes and has a sense of proportion, Your Highness doesn't have to worry!" Pingyuan Jun Zhao Sheng paused, and then suddenly asked: "Your Highness is going north this time, what is there I can help with!" ”

Zhao Jie thought for a moment, and then replied, "Your Excellency, give me a letter of recommendation!" In this way, I can meet General Li Mu more conveniently!"

"This is easy to hear!" Hearing this, Pingyuan Jun waved his pen, and in less than a pillar of incense, a letter stamped with the official seal of Pingyuan Jun was completed.

"You take this letter to see Li Mu, he will definitely settle you well!" Zhao Sheng, the king of the plains, comforted Zhao Jie and said: "The sword on the battlefield is not long-sighted, as the prince of Zhao State, don't risk the disapproval of the world, and always rush to the front line." ”

"I understand, Xie Junshang's guidance and concern." Zhao Jie continued while the iron was hot: "Now there are too many people around me, I hope that the monarch can take these people to Handan to settle down." ”

"Don't worry, Lone promised you! I'm sure they'll be happy and carefree! Hearing this, Pingyuan Jun promised Zhao Jie without thinking.

"That's where the kid is!" Zhao Jie thanked him and said, "See you tomorrow!" ”

The next day, the day Zhao Jie set off again. After bidding farewell to Zhao Sheng, the king of the plains, Zhao Jie carried the letter written by Zhao Sheng, the king of the plains, to Li Mu, the Taishou of Yanmen County, and led ten close guards and five hidden disciples of the Mo family to the crossing of the Yellow River again.

In ancient times when there were no trains, water transportation was the most convenient and fast mode of transportation, which allowed resources to flow rapidly, tribes and tribes intersected, and people interacted with each other. From ancient times to the present, people have dredged rivers or dug canals in order to obtain the convenience of water transportation, and the water network on the land of China has been dense, and cities near rivers have risen one after another. Water has ceased to be the source of life in human history, but has also begun to act as a source of power for transport.

During the Spring and Autumn Period and the Warring States Period, the princes of all countries worked hard to make the country rich and strong. The frequent mobilization of grain and grass troops has made the role of water transport increasingly prominent, so countries have introduced corresponding policies to control the river water network. Wu Guo dug a ditch to connect the Yangtze River and the Huai River, making the capital Gusu prosperous instantly; Wei repeatedly dredged rivers in the country, making Daliang City a cargo transportation hub in the Central Plains; The Qin State renovated the Wei River and the Yellow River every year, making the Guanzhong Plain rich in grains and prosperous. Without exception, all countries in the world do not use water transportation as much as possible to benefit their countries and people, and the convenience generated by the Yellow River, as a large river, will not be ignored by the countries along the river. During the Spring and Autumn Period, a grain transportation incident between the Qin and Jin states made full use of the convenience of the Yellow River waterway, confirming the development of shipping on the Yellow River in ancient times.

It is said that after the Jin Hui Gong of the Jin State ascended the throne, the Jin State encountered a famine for several years in a row, and the heavens were unkind so that the grains were not harvested, and the warehouses were empty so that the people were starving, so the Jin State decided to buy grain from foreign countries. Looking at the countries surrounding the Jin State, because the Qin State was the closest to the Jin State, and there was abundant food, and there was a marriage relationship, it became the only choice to borrow grain. However, the two countries had just had a dirty relationship, and the contradictions were growing day by day, but fortunately, the Qin State ignored the past suspicions and finally agreed to the request of the Jin State, which made the Jin State monarch and ministers breathe a sigh of relief. The Qin State transported grain to the team is huge, they sent a large number of ships to carry Wan Hu grain, starting from the Qin capital Yongcheng, along the Weishui, from west to east 500 miles of waterway to escort the grain, and then changed to a car transport, across the Yellow River and then changed to the Shanxi Fen River to transport north, directly to the Jin capital Jiangcheng. The white sail of transporting grain from the capital of Qin to the capital of Jin, the 800-mile road is connected from end to end, and it is called the "battle of rafting" in history. This operation to transport grain was a major event in the water transportation of inland rivers and an epic event in the navigation of the Yellow River. For the next thousand years, the Yellow River continued to be shipped. And Zhao Jie, inheriting the legacy of the ancestors, at this moment, was able to sit comfortably on the ship, and along the channel created by the ancestors towards Yanmen County, a destination that was quite far away.

Taking a stable boat, watching the magical scene of the original ecology on both sides of the river, and listening to the boatman telling the mysterious legend of the Yellow River, Zhao Jie and his party were not only happy, but also increased their knowledge, and they were very uncomfortable along the way.

Board the boat in Mengjin, go upstream, enter Sanmenxia, the boatman told Zhao Jie and others: Legend has it that when Yu controlled the water, he made the axe split the mountain into three canyons, such as "human gate", "divine gate", and "ghost gate", so it is called Sanmenxia.

Out of Sanmen Gorge, continue to go against the flow to the west, enter the land of Qinjing Anyi, as for Huashan and turn north, enter Pingyang County, South Korea, and then go to Yumen, the guide told Zhao Jie and others: Yumen is also called Longmen, according to legend, there are yellow carp from the sea and the rivers to fight for it every year, the first time to climb the Longmen, there are clouds and rain to follow, the heavenly fire burns its tail from the back, it is a dragon.

Yu Yumen got off the boat and walked, crossed the mouth of the pot, and the guide told Zhao Jie and others: Legend has it that Yu excavated the river in this place, the evil dragon blocked it, and the emperor heard it and suppressed the evil dragon with a pot here, so it was called the mouth of the pot.

After continuing to walk for a while, board the boat again, trace the river to the north, as for the land of Zhao Guodanlin, get off the boat and go eastward, and after five or six days, Zhao Jie and his party finally arrived at Yanmen County.
