I was engaged in infrastructure construction in the Han Dynasty [Transmigration Book]

Goblin?Isn't that another name for Cistanche?

Cistanche is parasitic and can survive in the desert. The seed survival time is short but the germination time is extremely fast.

Liu Tan couldn't help but slapped the table: Damn, isn't this a Haloxylon tree?

He is too familiar with Haloxylon tree.

No, it can’t be said to be familiar, anyway, it’s just that I’ve paid attention to it for a while.

In later generations, in order to protect the water and soil, the sandy areas were afforested little by little. At that time, Haloxylon was used in a large area because it was the most suitable.

At that time, Liu Tan had participated in various activities and even donated money to contribute to desert greening. He was very affectionate for the Haloxylon tree planted in the desert.

In the end, he didn't expect that he would forget about the Haloxylon tree after going around.

But he quickly remembered one thing: "Although the vegetation along the Yellow River is not abundant, it is still different from the desert. Shuo... Doesn't saltwood grow in the desert?"

Xu Lin smiled slightly: "Saltwood can grow in the desert just because it is tenacious enough, but it doesn't mean it won't grow in other places. The grassland people in too humid areas don't know if it can grow, but if it can't grow, then that At that time, the area where saltwood was originally planted should also be able to plant other plants."

Liu Tan was stunned: "So just use salt wood as a springboard, let it consolidate the water and soil before replacing it with other things?"

Xu Lin nodded: "Exactly, and in this process, the production of goblins can be regarded as some income."

Liu Tanxin said happily: "This method is good, but it still needs to be considered in the long run. It will not be possible to make a decision for a while. You can go back to the capital with me!"

Xu Lin didn't seem to expect that he would be passed so quickly, he was at a loss for a while, and then said in a low voice: "Caomin...Caomin, thank you Your Highness."

Liu Tan happily asked someone to get a tent for Xu Lin, and asked him to prepare to go with him tomorrow.

It has to be said that the appearance of Xu Lin relieved a lot of pressure on Liu Tan.

He knows how much he weighs. He doesn't know much about water control. What he knows is what he learned in geography class or later interested in popular science videos on a certain website.

Most of them are superficial understandings, allowing him to speak clearly and logically, but when he really starts to do it, he doesn't know how many detours he will take.

Although he is used to making detours in everything he does, water control is no joke.

With Xu Lin now, even if it seems that the other party agrees with him, if you really want to care about it, the other party must have more money in his stomach than him.

You must know that there is no Internet these days, the transmission of information is very, very slow, and even the knowledge tends to be conservative, and the unique knowledge of one's own family will not be easily taught to others.

In this case, it is necessary to be specialized in one aspect of understanding, and only after careful study can we sum up concepts that seem simple in later generations.

When Liu talked about this, he suddenly realized that he seemed to have forgotten to ask Xu Lin about his background.

It's also because Xu Lin's appearance is too non-aggressive, and no one thinks there is any danger to anyone in his appearance.

However, it doesn't matter, anyway, he has left people behind, just wait until tomorrow to ask.

So after setting off the next day, Liu Tan directly got the man into his carriage and asked, "I was in a hurry yesterday, and I haven't asked Xu Langjun where he learned from?"

Xu Lin said in a low voice: "This matter is wrong with Caomin. Caomin was worried about insulting his master, so he never reported his family background. Now that His Highness asked, naturally he can no longer hide it. Caomin has a master, surnamed Xu, with a single name. "

Oh, Uncle Xu.

Wait, Uncle Xu?

Liu Tan was startled, and when he was lying there stroking the panda, he sat up on his back.

Rolling Paralyzed was originally enjoying the loving caress of its two-legged beast father, but was suddenly pressed, and couldn't help humming.

Xu Lin was shocked immediately: "Isn't there someone in the car, Your Highness?"

Liu Tan: ...

What you said, there are so many people in the car, why are they not human?

Xu Lin seemed to realize his mistake, and quickly explained: "Caomin heard three breathing sounds when pedaling before, and thought... it was someone else."

Xu Lindun's slap was too meaningful, Liu Tanxin said, don't you think I'm a hidden beauty in a golden house, right?

Well, Jinwu Cangjiao... When thinking of Jinwu Cangjiao, he thought of his parents.

But that's not the point, Miao Rui explained: "It's the iron-eating beast raised by His Highness."

After saying these words, Xu Lin, who had been very calm since appearing in front of Liu Tan, couldn't help but move to the side, his voice trembling: "Eating... iron eating beast?"

Liu Tan comforted him and said, "Gun Gun is still young, so he doesn't have much attack power."

Xu Lin didn't seem to relax after hearing this, and was still very nervous, but he still didn't say anything.

Liu Tan was afraid that Gun Gun would frighten his newly recruited talent, so he reluctantly let Gun Gun go back to his own car.

Yes, Gun Gun has his own car, but this kid is clingy, and climbs into Liu Tan's car quickly every day without giving anyone else a chance.

After Gun Gun left, Xu Lin obviously relaxed a lot, and Liu Tan couldn't help asking, "Have you ever seen an iron-eating beast?"

After speaking, he felt that something was wrong, how could Xu Lin's eyes not see?

Xu Lin was silent for a while before whispering: "Caomin's family members were killed by iron-eating beasts, and they survived after meeting Master."

Liu Tan: ...

Gun Gun's coquettish and cute appearance always made him forget that this race is also a beast, and it is still a beast that can cause disasters in this era.

It's not that there are so many of them that they can't be kept in Shanglin Garden for hunting by Liu Che.

He couldn't make Xu Lin accept that Gun Gun was different, and the only thing he could do was to tell Xu Lin not to meet Gun Gun.

Liu Tan directly changed the subject and asked, "By the way, your master Xu Bo, is he the one who led people to dig the Longshou Canal?"

When mentioning his master, Xu Lin obviously had a lot of energy: "That's right, it's the teacher."

Liu Tan's eyes lit up and he asked, "Where is he now?"

This is an expert. The Longshou Canal is the first underground canal in the history of flower planters, and it is also the first to develop the Luohe River. It can even be said that it is a whimsical idea to use the well canal method to pass through Shangyan Mountain underground.

The most important thing is that he actually succeeded.

Xu Lin said in a low voice: "The master has passed away for more than ten years."

Liu Tan was taken aback, feeling regretful in his heart, but there was nothing he could do about it. He asked with a smile, "It's okay, you can be regarded as inheriting your master's mantle now, eh, no, your master has been digging canals to divert water in the Luoshui area. , why did you come to Hetao?"

Xu Lin explained: "Master's family was ruined because of the diversion of the Yellow River. Since then, he has always wanted to control the Yellow River, so he traveled all the way along the Yellow River. It's a pity that the blow was too big. Coupled with the lack of medical treatment, some people even When I was young, I didn’t even have to eat, which caused Master’s health to go from bad to worse, so...the old man collapsed before finishing the walk, and now Cao Min is considered to inherit Master’s behest, and even if he spends his whole life, he must try his best to control the flood of the Yellow River.”

Liu Tan frowned: "Lack of medical care? No food? How did this happen? What happened?"
