The day they chose was good. It was sunny that day. Of course, it rarely rained in the Northern Kingdom, and the sun was shining most of the time.

The hotter the sun got, the more the newly built cement dam seemed to be something otherworldly.

The beauty of industry and technology is probably something that no one can resist.

Liu Che stood in the distance and watched for a long time. After he came to his senses, he couldn't wait to go over and take a look.

The closer he walked to the dam, the more he could feel how tall it was.

The height of the dam is at least ten meters, and its width is even more extraordinary. If you only look at the top of the dam, you will naturally feel that it is not wide enough. However, when people stand on it and look down, they will find that the entire dam is slanted downward on both sides.

The bottom width is at least three times that of the top.

Such a project can be considered a giant project for the Han Dynasty.

Liu Che walked around the dam and found that the entire dam was very exquisite from any angle, without any shoddy workmanship.

After coming down, he couldn't help but turn around and look at Liu Tan and ask, "How long did it take to build this dam?"

Liu Tan said, "It took more than four months."

Liu Che was fine, but the officials following them all gasped. They couldn't believe that this could be built in four months.

Liu Tan was afraid that Liu Che would think he had used some magic again, so he quickly said, "This time, it was supervised by the Mountain and River Messenger under my command. I didn't ask much about it from beginning to end."

Liu Che asked, "Is it all him?"

Liu Tan hesitated for a moment and said, "I designed the form of the dam."

Liu Che asked curiously, "Where did that mountain and river envoy come from? Why haven't you heard about him before?"

Liu Tan hesitated for a moment before saying, "The Mountain and River Messenger is called Xu Lin. I met him by chance when I was out exploring."

"Xu Lin?" Liu Che read the name and couldn't help but ask, "What is his relationship with Xu Bo?"

Liu Tan was surprised that Liu Che still remembered Xu Bo, so he said, "He is Xu Bo's apprentice."

Liu Che sighed and said, "No wonder. The Longshou Canal designed by Xu Bo was also quite good. Eh? Where is Xu Lin?"

Liu Tan hesitated for a moment and said, "Xu Lin is disabled and was afraid of being disrespectful to the emperor, so he didn't come."

"Disabled?" Liu Che asked, "What's the matter?"

Liu Tan sighed and said, "He didn't come from a good family. His family was poor, and he developed a disease that not only made him unable to walk, but also blind. Luckily, he met Xu Bo, but he still couldn't be cured. He had already supervised the construction of a dam, which was smaller than this one. I originally wanted him to stay in Shuofang City to recover, but he was so anxious that he told Huo Guang and ran out to start building this dam."

Liu Che didn't feel anything after hearing this. There were too many poor people those days, and some even starved to death. In comparison, Xu Lin was actually lucky to be able to survive.

He simply waved his hand and said, "He is a meritorious official after all. Since I am here, I must meet him."

Liu Tan immediately turned around and said, "Go and bring Xu Lin over."

How could it be wrong for a meritorious official to be absent at the critical moment of opening the floodgates? In fact, even if Liu Che did not mention this matter, he would have found a way to mention Xu Lin, and always let Xu Lin dart before Liu Che's eyes. As long as Liu Che still remembered Xu Bo's contribution, he would not treat him badly.

After all, the Mountain and River Envoy was an official position created by Liu Tan himself. He was subordinate to the King of the Northern Territory, but was not within the formal regulations of the court.

Liu Tan wanted to ask for a title for Xu Lin. Even if the contribution of the two dams was not enough, at least he could enter the court first, and then take his time. Anyway, Liu Tan had confidence in Xu Lin. After more dams were built, Xu Lin might not only develop water conservancy in the Northern Border Country, but also go to other places. Then the title would inevitably come sooner or later.

After Liu Tan finished speaking, Xiao Cheng behind him immediately ran to pass on the message. Not long after, Xiao Cheng came over pushing Xu Lin.

Liu Tan turned around and found that the blue cloth covering Xu Lin's eyes had been taken off. Only then did he see Xu Lin's eyes.

The shape of Xu Lin's eyes is not very good-looking, but because his eyes are a little hazy, they look a little different.

Xu Lin was very nervous at this time, but he still saluted Liu Che and said, "Your Majesty, I pay my respects to you. I have a disabled leg, so please forgive me for my rudeness."

"No problem." Liu Che looked at Xu Lin curiously, then asked Liu Tan, "Didn't you say he also has eye problems?"

Liu Tan said, "That's true, but the doctor said that if you take good care of yourself, you should be able to recover a little."

After he finished speaking, he looked down at Xu Lin and asked, "Could it be that it has already worked?"

Xu Lin smiled and said, "Thank you for your concern, Your Highness. I've gotten better after taking the medicine prescribed by the doctor. I can see a little now. It's not very clear, but compared to before, I'm satisfied."

Liu Tan patted his shoulder and said, "It will get better. Okay, come here and help me introduce this dam to His Majesty. I didn't supervise its construction, so I feel like there are many things I can't explain well."

Xu Lin might have been a little timid when facing Liu Che, but when it came to his professional field, he became more confident and began to radiate dazzling brilliance.

And I don’t know if it’s because he’s worked hard to lobby officials in the past, so what he said when he explained was really easy to understand.

This easy to understand does not mean the kind of easy to understand for people with low cultural level, but it is the kind of easy to understand that uses the most elegant words with a certain level of literary accomplishment.

Liu Tan couldn't compare to Lu Xuan in terms of skill. He approached Lu Xuan, looked at Xu Lin, and said with a smile, "My taste is pretty good, isn't it?"

Lu Xuan looked at Xu Lin and then looked around. While everyone's attention was focused on Xu Lin, he reached out and covered Liu Tan's eyes.

Liu Tan was startled by him and quickly grabbed his wrist, pulled his hand off and lowered his voice: "What are you doing?"

Lu Xuan said seriously, "Don't look at others like that."

After hearing this, Liu Tan chuckled softly, "What? Are you jealous?"

"Yeah." Lu Xuan admitted it straightforwardly, at least much more straightforward than him admitting his fear of heights.

Oh, that's not right. He still hasn't admitted that he is afraid of heights.

This time, it was Liu Tan who felt uncomfortable. He coughed lightly and said, "What are you thinking? I just treat him as a good assistant."

His look is purely admiring, okay?

Lu Xuan didn't say anything, but just scratched his palm, which made Liu Tan quite nervous.

Although the wide sleeves could cover up the little movements between the two of them, the problem was that it wasn't right for them to stand so close to each other.

Seeing his guilty look, Lu Xuan couldn't help but lean over and smiled, "I've been staying by His Majesty's side these days. Everyone... must have figured it out already. There's no need to be so nervous."

Liu Tan rolled his eyes at him and said, "What nonsense are you talking about?"

After saying this, he withdrew his hand and took two steps to the side. Unexpectedly, Lu Xuan also took two steps and said, "If you don't believe me, send someone to investigate. I'm sure my guess is correct."

Liu Tan wrinkled his nose. "No matter what others think, we must do things on the surface. If we dare to quarrel in front of everyone, my father will make sure we never see each other again. Do you believe it?"

Lu Xuan originally wanted to tease Liu Tan. After all, it was quite cute to see Liu Tan blushing while trying to remain calm while being teased.

But when he heard what Liu Tan said, he immediately stood up straight, and in a second he turned from a playboy prince into a serious man, with a straight body and a serious expression, as if it was not him who had just teased Liu Tan.

Liu Tan couldn't help but rolled his eyes at him twice. At this time, Xu Lin had just said something similar to what Liu Che said. Liu Che subconsciously wanted to find his son, but found that his son was not around. When he looked up, he found that his son and the King of Wusun were standing side by side. Although there was a long distance between the two people, that distance was full of four words - the more you try to hide, the more obvious it becomes.

Liu Che paused, then pretended not to notice anything: "Why are you standing so far away? Come here."

Liu Tan walked over and said, "Nothing, just looking around. This canal is much bigger than the one we dug before."

Liu Che said with some emotion: "I didn't expect that the dam could have so many functions. No wonder you put so much effort into building it."

Liu Tan was stunned for a moment and couldn't help but glance at Xu Lin.

I really want to know how Xu Lin fooled his father just now. One of the purposes of building the dam was to improve flooding and form an irrigation network in this plain. It has no other functions.

Liu Che should have been able to understand these two effects, right? It wouldn't have caused him to sigh, right?

Unfortunately, Xu Lin, who was half-blind, didn't notice Liu Tan's gaze and was still smiling proudly. Liu Tan could only smile awkwardly and said, "Yes... yes, otherwise, wouldn't all the money spent be wasted?"

Although I don’t know what Xu Lin said or what Liu Che felt, the universal answer cannot be wrong.

Liu Che nodded and asked, "Is it almost the auspicious time?"

They have been chatting here for a long time, and it should be almost time.

Liu Tan turned around to take a look, and Zhu Shanfu immediately said, "Everything is ready upstairs."

Well, the so-called preparation above is a small platform built not far from the dam. From there, one can vaguely see the Yellow River in front. The dam is originally lower than where they are, so this position just happens to allow one to see the entire dam.

At this time, the food table had been set up on the platform, with fine wine and various snacks and fruits on it, waiting for Liu Che to go up and eat and drink with everyone and watch the opening ceremony, oh no, it was the floodgate opening ceremony.

After Liu Che sat down on the throne, the auspicious moment arrived. With a loud cry, "Break the dam!"

The original banks of the Yellow River quickly melted and collapsed.

Liu Che, who was drinking, couldn't help but put down the wine glass in his hand, and the officials behind him couldn't help but lean forward and feel nervous - the Yellow River bursting its dike always represents a disaster.

This was the first time that everyone saw someone deliberately causing the Yellow River to burst its banks. For a moment, everyone was very worried, as if they had seen the Yellow River flooding.

However, no, the water of the Yellow River rushed and roared, crashing into the dam.

The massive dam remained motionless despite the impact, as if the force was insignificant.

The surging waves were blocked, and the water could only pour down through the sluice gate.
