Li Chengqian of the Tang Dynasty: Please say long live His Majesty

Chapter 573: Continue to deduce the Tuibei Tu (Part )
In late June, it was drizzling.

Beiyuan.

The Wei River tide is rising.

Li Chengqian stood beside the canal, looking at the canal water that was about to rush ashore, his face became solemn.

"The Yellow River breached its dikes four times this year. Three of these were repaired in time, preventing major damage. However, one dike still overflowed, affecting half a state. Although I executed the local governor, the damage remains difficult to control. We can only wait for the flood to subside." Li Chengqian turned sideways and looked at Yan Liben. "Mr. Yan, do you have a way to completely stop the Yellow River from flooding?"

Yan Liben suddenly smiled wryly and said, "Your Majesty, the Yellow River has been a difficult problem throughout history. Before the Han Dynasty, it was flooding to its extreme. It wasn't until the reign of Emperor Ming of Han, when Wang Jing regulated the river, that the Yellow River was stabilized for hundreds of years. However, in recent years, the sediment in the Yellow River has increased again, causing constant flooding."

Li Chengqian nodded slightly and raised his hand to signal Yan Liben to continue.

"Wang Jing used two methods to control the Yellow River. One was to build internal and external dikes. During the dry season, the Yellow River was confined to a narrow section of the dike. During the flood season, the Yellow River was diverted into the diversion dam to reduce the damage caused by the Yellow River."

After a brief pause, Yan Liben said helplessly: "The second method is to dredge sand during the dry season of the Yellow River."

Li Chengqian nodded slightly. The first method had some of the characteristics of restraining water and attacking sand.

Yan Liben glanced at Li Chengqian and continued, "Although dredging sounds simple, the Yellow River is nearly two thousand miles long. It would be too labor-intensive, and planning would also be a challenge. Furthermore, while surface sediment is easy to remove, dredging deeper sediment could easily lead to epidemics."

The deep mud and sand carry hundreds of years of pathogens, and who knows what kind of plague it will cause.

Li Chengqian looked up at Yan Liben and asked, "Is raising the levees the only way the Tang Dynasty can control the Yellow River now? Mr. Yan, it's been over six hundred years since Wang Jing's incident, and the Yellow River's silt has increased again. The damage can still be controlled now, but what about the future, a hundred years from now?"

"If Your Majesty is willing to tame the Yellow River, I am willing to do my utmost to assist you." Yan Liben bowed and said, "Your Majesty, the most feasible method is to build a diversion canal that can reach the sea. For example, Yang Guang built the Grand Canal to connect the north and the south, but in fact, it also improved the Yellow River's course in some areas and played a role in flood diversion. If you can follow his example..."

"The Grand Canal!" Li Chengqian raised his head, looking towards the Beiyuan Garden in front of him, and said softly, "I'm afraid it will cost quite a bit."

"Yes!" Yan Liben cupped his hands and said, "It's at least over 1 billion coins. If we don't even consider the people's strength, it may cause human disasters. Not to mention, Your Majesty also has to conquer Goguryeo in the east and Tubo in the west. If you do it all at once, I'm afraid we will not be able to escape the lesson of the fall of the Sui Dynasty!"

"Alright." Li Chengqian waved his hand and said, "Let's put it aside for now. Once the war is over, we can proceed with the management of the Yellow River in sections. My dear minister, go with the Ministry of Works, the Ministry of Construction, and the Ministry of Water Resources, and find a way to properly manage it."

"I obey your order." Yan Liben breathed a sigh of relief.

Li Chengqian nodded, then walked along the canal towards the Daming Palace.

Today, the Daming Palace has resumed construction and is expected to be completed before the end of the year.

Li Chengqian raised his eyes and looked towards Luoyang.

A wry smile in his eyes.

He also wanted to build the Daming Palace, conquer Goguryeo, and in the future conquer Tubo and wage war westward.

It is only in these years that the Yellow River has been relatively stable, otherwise the chaos of the Sui Dynasty would have immediately befallen the Tang Dynasty.

Li Chengqian raised his head and looked at the gloomy sky.

Since last year, annual rainfall has been gradually increasing, and there have been signs of flooding for several consecutive years.

Li Chengqian shook his head. In front of him, the number of water wheels around the Daming Palace began to increase.

……

Daming Palace, Purple Palace.

Li Chengqian was standing on the steps, with Yan Liben, Qiu Xingyan, Yang Wulian, Li Chunfeng and Zhao Yuankai standing behind him.

The five people looked from Li Chengqian to outside the hall.

It's still raining outside.

Li Chengqian turned around and looked at Li Chunfeng: "Mr. Li!"

"Your Majesty!" Li Chunfeng bowed seriously.

"You saw the water wheels and windmills around the canal just now. Is there any way to use windmills to scoop sand from the Yellow River? If we can have such a boat, we can clear the silt from Sanmenxia to the Yellow River estuary, even if it can alleviate the flood of the Yellow River a little, it will be a great contribution to the world." Li Chengqian looked straight at Li Chunfeng.

"You can try, but I think there will be countless difficulties." Li Chunfeng bowed with some embarrassment.

"Do it first." Li Chengqian looked at Yan Liben, Qiu Xingyan, Yang Wulian, and Zhao Yuankai and said, "If there is anything, ask these four for help."

"Yes!" Li Chunfeng bowed bitterly.

Li Chengqian looked at the other four people with a serious expression: "Two years later, the army will attack Goguryeo, and all kinds of military equipment must be fully prepared.

My Lords, make good plans, deploy and execute, mobilize those who need to mobilize, dig those who need to dig, and do not delay matters at the front line of the army."

"Yes!" The four of them bowed in unison.

Li Chengqian waved his hand slightly, and the four people immediately bowed and then retreated.

For a moment, only Li Chengqian and Li Chunfeng were left in the hall.

"Your Majesty!" Li Chunfeng couldn't help but bow first.

Li Chengqian nodded calmly and said, "Do you know about Yuan Tiangang's situation?"

"Yuan..." Li Chunfeng talked for a long time, but couldn't utter the word "thief". He could only bow to Li Chengqian and said, "Your Majesty, I am guilty. I failed to recognize the true face of the thief and almost caused the country to be in turmoil. Please punish me severely."

Li Chunfeng was the Grand Historian, and he knew very well the power that a prophecy could cause.

The phrase "Peach and plum trees are so abundant that floods surround Yangshan" made Li Tang's kingdom completely recognized by people all over the world.

Because of this prophecy, countless people died.

Now, if the saying "The Tang Dynasty lasted for three generations, and a female ruler, King Wu, succeeded the Tang Dynasty" were to come true, the entire Tang Dynasty would be overthrown.

Especially since the emperor in front of him was the third emperor of the Tang Dynasty.

Li Chunfeng knew very well how big a mistake he had made, especially since Yuan Tiangang was his teacher.

Li Chengqian glanced at Li Chunfeng, walked past him, and then walked up to the imperial steps and sat down on the imperial couch. "Your last name is Li, do you think I won't trust you?" Li Chengqian asked softly, and Li Chunfeng felt tears welling up in his eyes uncontrollably.

"Your Majesty!" Li Chunfeng bowed solemnly.

Li Chengqian sighed softly and said, "I didn't even pursue Master Yuan Ke's case regarding Yuan Tiangang. Do you think I will pursue you?"

Li Chunfeng tried hard to control his tears, and bowed solemnly, "Thank you, Your Majesty!"

Li Chengqian waved his hand directly: "Alright, stop being so childish. I kept you here because I need you to do something."

"Yes!" Li Chunfeng then collected his composure and stood up seriously.

Li Chengqian nodded and said, "First, let's talk about what happened just now. You are an expert in wind power. How can you use windmills to repair the canal? You can come up with your own ideas. If it is feasible, you can apply it to waterwheels."

"Yes!" Li Chunfeng continued to bow.

"The second thing." Li Chengqian sighed and said, "Although I am not an expert in Feng Shui, I have noticed that the moisture in the world has been very high in the past two years. There may be heavy rain next year. Therefore, I will transfer people from the Hundred Cavalry Division to the Imperial History Bureau. Then, the Imperial History Bureau will monitor the Feng Shui of the world and those who are unruly. At the same time, I will cooperate with the Capital Water Conservancy Bureau to control the waterways of the world."

"I obey your order." Li Chunfeng bowed with a serious expression. This was a big deal.

"Finally, let's talk about the Tui Bei Tu." Seeing Li Chunfeng look up in surprise, Li Chengqian waved his hand and said, "Although Yuan Tiangang has ill intentions, his calculations are ingenious. In particular, he has observed the great changes over the past century and can detect hidden dangers that even I cannot perceive. This matter is top secret, but you must continue."

"I obey your command." Li Chunfeng saluted seriously.

……

sunset.

I didn't realize it was time for the next shift.

In the Taiji Hall, Li Chengqian stretched lazily.

At this moment, Xu An came in from the side hall and handed a secret memorial to Li Chengqian on the imperial couch.

Li Chengqian looked at him in surprise, then opened the memorial.

The correspondence between Yang Sina, the assistant minister of the Ministry of Justice, and Li Yuanjing, the Prince of Jing, increased.

Prince of Jing Li Yuanjing and his son-in-law Fang Yiai had frequent correspondence.

Li Chengqian looked at the two lines of words in front of him, and his breathing gradually became heavier.

Sure enough it started.

Princess Gaoyang's rebellion case.

Fang Yiai, Fang Yize, Li Yuanjing, Chai Lingwu, Li Ke and a group of people,

Li Ke may have been wronged in this matter, but the intervention of the Hongnong Yang family made things more complicated.

And there is Chai Lingwu.

It has been a long time since Chai Lingwu's name appeared in Li Chengqian's mind.

The reason why his name popped up at this moment was because Chai Zhewei was now the general of the imperial guards and would be on duty at Xuanwu Gate from time to time.

Sure enough, the inertia of history eventually rolls forward.

Now, Fang Yiai may not have realized Li Yuanjing's evil intentions. After all, Li Chengqian promised him to march east to Goguryeo two years later.

Similarly, Li Yuanjing probably hasn't realized Yang Sina's sinister intentions yet.

These people!

Li Chengqian's finger fell on Fang Yiai's name.

He is the core of all this!
Although Li Yuanjing was a member of the royal family, he had little influence in both civil and military affairs.

Although Yang Sina has the Hongnong Yang family behind him, to be honest, it is precisely because they have the Hongnong Yang family behind them that countless people are afraid of and wary of them.

But Fang Yiai was different. He had extraordinary martial arts skills, was a son-in-law of the emperor, and had connections left by Fang Xuanling.

In addition, although Fang Yiai had not been in contact with Chai Lingwu for many years, they had both worked for Li Tai after all.

Now, Li Xin is also outside the palace.

Once these people join forces, there is a possibility that something big will happen.

Li Chengqian calmly handed the memorial back to Xu An and said calmly, "Keep watching."

"Yes!" Xu An bowed, turned around and left quickly.

Li Chengqian lowered his head and reached out to open the last memorial in his hand.

With just one glance, his expression turned horribly ugly.

He raised his head, looked at Dou Dexuan on the side, and said in a cold voice: "Xuan Youwei General Xue Wanche!"

"Yes!" Dou Dexuan's heart suddenly tightened. He stood up and bowed to Li Chengqian, then turned around and walked quickly out of the hall.

He understood the emperor, and he understood his anger even better.

Therefore, he led Xue Wanche to the Liangyi Hall as quickly as possible.

"Your Majesty!" Xue Wanche stood in the hall and bowed in confusion.

Li Chengqian directly picked up the memorial and slammed it in Xue Wanche's face, shouting angrily, "Explain to me what it means that the emperor doesn't know how to employ people."

Xue Wanche was stunned, looking at the memorial that fell to the ground:
I, the Palace Attendant Censor Wei Renyue, impeached the Right Guard General and the Imperial Concubine Xue Wanche, expressing my resentment.
