When Li Yan mentioned his daughter's knowledge, Zhao Fu's face became a little sad. The person who taught his daughter Yifan was indeed a famous teacher, and he was also a famous figure in the Tang Dynasty. However, if possible, he would rather his daughter be an ordinary person who knew nothing.

"Your Highness, the other party cannot be regarded as Yifan's master. But he saw Yifan's talent, so he taught her for a while. Unfortunately, this man was not in the end and didn't know where to travel now?" Zhao Fu sighed and said.

"Oh, who is the other party?" Li Yan was curious, but did not notice Zhao Fu's strangeness.

"The other party is Yuan Tiangang, the old immortal Yuan!" Zhao Fu bowed and replied.

Li Yan was very surprised when he heard this. He didn't expect that Yifan's master was Yuan Tiangang. No wonder he was so knowledgeable. Although the other party was a charlatan, not everyone could do charlatans. Astronomy and geography are just the basics of entry. In addition, you have to do something like that, such as calculating. Otherwise, it would be so easy to fool others?

Just when Li Yan was unscrupulous in plotting against the people of Dengzhou, several merchant ships were flowing down the winding Yellow River. They had just arrived at the Bianzhou River section. There were several people standing on the bow of the largest merchant ship in front. Two people dressed in men in front were climbing on the side of the boat, as if they were about to salvage something from the water. Behind him was a short and fat businessman, and two people in Taoist uniforms stood behind the three, lowering their heads and talking about something.

In this strange combination, it was obviously the two Taoist priests who were headed by the two Taoists. The older Taoist priest looked fifty or sixty years old, his hair had turned gray, his face was ancient and thin, and his long beard floated on his chest, looking like a fairy-like and immortal, and he looked like a god who was not as good as the world's fireworks. The young one looked in his thirties, very handsome, and had short beards on his lips. He added a bit of maturity to his handsomeness. If he was later, he could definitely kill a group of ignorant girls in seconds.

"Please look at the old god, the water is coming!" The two guys beside the boat were fetching water from the Yellow River. After the short and fat businessman took it, he immediately sent it to the elderly Taoist priest and said with a flattering look on his face.

The older Taoist priest took the river water, stretched out his fingers and dipped it in the water. After the water on his fingers dried up, he rubbed his fingers gently, and a few traces of invisible mud and sand flew out between his fingers and was quickly blown away by the river wind.

"Well, the water in the Bianzhou River section is almost the same as the upper reaches. It is a little turbid than last year." The older Taoist priest said with some concern. It turned out that he was using this method to test the silt content in the river water. The young Taoist priest next to him looked like he knew it would be like this, obviously he knew it would be the result.

"Master Yuan, you have been monitoring the Yellow River water for many years. Now it is certain that the mud and sand contained in the Yellow River water is increasing year by year. The reason is nothing more than that of the damage to the upper reaches. If it is not managed in time, I am afraid that the disasters along the Yellow River will suffer more than ten times more than now." The young Taoist priest said slowly.

"Well, it's not bad, but the river water is doing better this year than in previous years. At least it's not as fast as in previous years. But I don't know why?" The elderly Taoist priest rubbed the mud and sand in his hands and said with a puzzled look on his face.

"Haha, I have to thank His Highness the King of Qi in our Tang Dynasty!" The young Taoist priest suddenly laughed.

"Chunfeng, does this actually have something to do with His Highness King Qi?" asked the older Taoist priest with surprise. The identities of these two Taoist priests are extraordinary. The young one is the famous Li Chunfeng in history, and is currently the Grand Historian of the Tang Dynasty. And the one who can be called a master and has a surname of Yuan is naturally the charlatan Yuan Tiangang mentioned by Li Yan.

"Master Yuan doesn't know. Last year, His Highness of Qi used charcoal instead of firewood or charcoal. Now, not only Chang'an, but almost the entire Guanzhong area uses charcoal as fuel. In addition, the invention of cement, when building houses and palaces, it can also replace wood in many places. Therefore, since last year, the amount of trees cut by Guanzhong and Shanghai in the Yellow River has been significantly reduced. I believe that with the promotion of carbohydrate and cement, the demand for trees in the Tang Dynasty will further shrink. Then I will write to Your Majesty to request the rest and recuperation of the plants and trees in the Guanzhong area. I believe that in a few years, the water of the Yellow River will become clear again."

Li Chunfeng looked so full of spirit. When he mentioned Li Yan, he also had respect in his tone. The reason why he agreed to go to Dengzhou with his master Yuan Tiangang was that in addition to seeing the junior sister who was praised by his master, he also wanted to meet the King of Qi Li Yan. In fact, he wanted to meet Li Yan last year, but unfortunately he had never found a suitable opportunity. He took the liberty to visit him and seemed too abrupt, so he had not been able to meet him until now. However, it was different when he arrived in Dengzhou. His junior sister's father was a Dengzhou Bianjia. You can ask him to introduce him on that time.

"So that's it!" When Li Yan mentioned, Yuan Tiangang also smiled. "I have only been traveling abroad for a few years this time, but when I returned to Chang'an, I found that in the entire Chang'an city, whether it was a street corner restaurant or a noble man's mansion, almost all of us, King Qi, were talking about our King of Qi. I really wish I could meet as soon as possible. At that time, I must take a good look at his face."

Seeing that the master rarely showed a hint of anxiety, Li Chunfeng also found it interesting. However, when he mentioned his face, he remembered a strange thing that the master told him, so he asked: "Master Yuan, you mentioned it to your disciple last time that the faces of many noble people in Chang'an City had changed. At that time, he thought that the reasons were not possible. Have you clarified it now?"

"Oh, this fact makes me puzzled. When I was in Chang'an a few years ago, I met many people. However, this year I returned to Chang'an, I found that many people's faces had undergone tremendous changes. For example, Li Jingye, the grandson of the British Duke, was born rich and noble, but died of swords and weapons. The second son of the Fang Xiang was also a person who was difficult to die for good. There were even His Highness, Princess Jinyang, etc., but now the faces of these people have changed, and they all have become long-lived and blessed lives, which is really hard to understand."

Yuan Tiangang shook his head and sighed, although a person's destiny is not fixed, it has a context to find. Even if there are changes, it is rare to jump out of this context. However, now there are so many people who have rewritten their own destiny at once, which is really incomprehensible to people.

"Master Yuan, don't be too upset. Actually, I have encountered this problem. I have calculated the national destiny of the Tang Dynasty before and probably knew a little, but now it's all messy. I can't calculate the national destiny after the Tang Dynasty. I have been studying this matter last year, but in the end I still felt like I fell into a fog and couldn't figure out the cause and effect at all. In the end, I had to give up helplessly." Li Chunfeng also shook his head and smiled bitterly.

Yuan Tiangang is best at appearance, while Li Chunfeng is most proficient in calculation techniques. This is not a trick used by fortune tellers on the street to deceive people, but a real mastery. However, these two kinds of knowledge are too profound and must have profound attainments in math, medicine, philosophy, etc. Even with talented people like Yuan Tiangang and Li Chunfeng, they can only specialize in one subject. In the history of the entire Chinese land, not many people are proficient in this method. Instead, many people use the names of physiognomy and math to deceive money and reputation. Over time, they will ruin the reputation of the two subjects.

Speaking of this, the two suddenly looked at each other at the same time, and then smiled bitterly. Although there was no tangible evidence, their intuition told themselves that this matter must be related to the magical King of Qi.

"Two immortal masters, the bow of the boat is very windy. Come in. I have the best fried tea here. This is from the fried tea factory in the Qi Wang Mansion. Compared with those later fried tea factories, the taste is the most pure!" At this moment, the short and fat businessman just greeted the two in the boat warehouse.

The businessman's name is Qian Gui. As his name is, this guy is really a "Qiangui". Although his parents are not very good, he is like Wang Zihao. He is one of the top ten wealthy businessmen in Chang'an City. He specializes in luxury goods such as jewelry and jade. He has been guided by Yuan Tiangang before. This time, when he heard that the old god was going to Dengzhou, he happened to be escorting a batch of goods to Dengzhou, so he immediately came to invite him at home.

"Qiangui, what kind of goods are you transporting in this batch? You actually want you to escort them in person?" Yuan Tiangang and Li Chunfeng heard this, and smiled and entered the warehouse to drink tea. Yuan Tiangang was familiar with each other, so he asked casually.

"You old immortal, there is nothing particularly valuable on other ships. It is the Five Kings Zui and Fireworks that I have spent my energy to get. However, our ship is full of perfume and mirrors. These two things cost no less than 100,000 yuan. If something happens, I will even have the desire to die." Qian Gui said exaggeratedly. With his wealth, if this ship of cargo is gone, it will be at most abrupt and not yet dead.

"Oh? Aren't you doing jewelry and jade business? Why are you all the people who are transported this time?" Yuan Tiangang asked strangely.

"Hehe, old god, you are not a businessman and don't know the market. If these perfumes and mirrors on our ship are transported to Dengzhou, they will be several times more profitable. However, the marine merchants in Dengzhou will be shipped to Goguryeo or Japan. The goods of 100,000 yuan can be sold at least one million yuan, which is more profitable than jewelry and jade." When talking about business, Qian Gui immediately shone his eyes. Although he is rich, he still saliva when he thinks about the sky-high price of 100,000 yuan.

"It's a pity that I don't have a sea boat in my hand and I'm not familiar with the overseas countries, otherwise I'd sent it to Goguryeo." Qian Gui then said unwillingly.

Seeing this wealthy businessman's greedy appearance, Yuan Tiangang and Li Chunfeng did not look any contempt, but shook their heads helplessly. At the same time, they thought that the influence of His Highness the King of Qi was really everywhere. Even the merchant ship they were riding was filled with new goods produced by Li Yan.
