The knowledge introduced in that book was too advanced, and there were many means that they had not been able to complete until now.

Even if you understand it, you don't have the technology to do it.

I have to say that the dam construction method and the method of controlling the flood drawn on the drawings are very useful.

But how do you use it?

Now Qi Lichen is not here, and he doesn't know where to ask a lot of things he doesn't understand, so the progress is very slow, so he asked Xu Buzhi to take the book and go to Xi Muyun, but so far, he has only found materials suitable for building a dam.

Qi Lichen also cut off the news, and he didn't know how the progress was on his side.

Just looking at the map at a loss, someone outside suddenly came to report, "Oh no, Fifth Prince, the mountain in front of you is landslided, and the road is blocked." ”

"It's raining for the past two days." Gu Jianglin walked out of the temporary residence, the cold rain was dripping, although it was almost spring, and the spring tide was flooding, but in the air, there was still a little chill.

"It's still too cold, I don't know, it's too cold, and the materials used to build the dam tend to solidify, so it's not time yet." Gu Jianglin said with a little worry.

It's better in the city, but some villages near the mountains are flooded, especially in the surrounding mountains, where the rain is pouring and it is easy for landslides to turn into mudslides, which is another disaster.

"Have all the people inside been evacuated?" Gu Jianglin asked.

It had been raining heavily for the past two days, so in order to prevent casualties, preparations had been made for a long time.

"All evacuated." The subordinate replied.

"That's good." Gu Jianglin glanced at the map again, and asked him to mark several key points, which are suitable for building a dam, but he still has to conduct a field investigation, "Let's go here and take a look, is Lord Wang from the Ministry of Industry here?" He is the best at water conservancy, and there are many things I have to discuss with him. ”

"I've already entered Yanzhou, and I'm repairing at the post station." Subordinate Dao.

"I'll go to this point first, and you can send someone to call Lord Wang, so that he can take a good look at where the dam is suitable for construction." Gu Jianglin said.

He also redrew two of the drawings in the book, because after repeated research, he felt that the two schemes were very suitable, but he was not proficient in this aspect, so he never dared to draw conclusions to start the work.

And they can't find a lot of the materials above, and now is not the time to start construction, there is still time, and there is no hurry.

The subordinate answered and retreated.

Gu Jianglin set off immediately.

The river is twice as wide as usual, and in some places it has already drained, flooding many farmland and villages, and standing on the bank of the river, you can feel the ground beneath your feet as if you were not careful, as if you were not careful.

The subordinate standing behind him hurriedly said: "The fifth prince is too dangerous, there is a stone abutment over there, go over there." ”

Gu Jianglin didn't care about this, he was more concerned about the safety of the people living on both sides of the river than his own safety.

The Ministry of Works, Lord Wang, soon arrived.

Wang Zhao is very good at water conservancy, and was rewarded by the emperor for his meritorious work in water control, but the flood he encountered that year was far less severe than this year.

When the flood first occurred, the emperor also asked Wang Zhao to find a reasonable plan to deal with the disaster, but Wang Zhao excused himself and said that he had no choice.

Now it is not him who is in charge, but he has been sent to help.

Gu Jianglin still believed in his ability very much, he didn't deliberately come up with such a way before, but maybe there was really no plan to cure the disaster.

When Wang Zhao came, he immediately asked Gu Jianglin for peace

Gu Jianglin helped him up, smiled and said, "Lord Wang is polite." ”

Wang Zhao raised his head and smiled, "I haven't seen you for a long time, how are the five princes doing lately?" ”2018

"It's all good." Gu Jianglin coughed lightly, "It's just that the victims of this disaster are uneasy for a day, and the water conservancy matter will not be completed for a day, and this prince is uncertain." ”

Wang Zhao nodded, "The fifth prince really cares about the people. "Let's say, and looked into the distance again, "This year is indeed much more serious than that year, back then I just used sacks of gravel and sand to stop the water, combined with the weather, while the water has the intention of dissipating, raise the embankment, can be safed for decades, but this year's flood is obviously much more serious than that year, ordinary methods are useless." ”

"yes." Gu Jianglin said: "When the tide rises in spring, it will always be a disaster, so this prince wants to do it once and for all. ”

"Is there a way for the five princes?" Wang Zhao asked curiously.

Gu Jianglin nodded, took out the two drawings from his body and handed them to Wang Zhao, "How about you take a look at this dam?" ”

Wang Zhao took the drawing, although there was no written description, but looking at the various details on this drawing, he understood that if the dam above it was built, it would be a shocking work.

"Where did this picture come from?" He was amazed.

"From a friend." Gu Jianglin said.

Naturally, he can't tell the origin of this thing, and sometimes, the husband is not guilty, but he is guilty.

It's also a treasure.

Wang Zhao knew from his vague words that it was not appropriate to ask any more questions, so he continued to look at the picture, and after looking at it for a long time, he said: "I have never seen this method, but I also know that because the rivers are different, the method of building dams must also be changed, for example, where there is a lot of sediment, the river channel must be emptied, and the foundation pillars must be lowered, like this river, the ground is mostly gravel, and it is more difficult to clean up. ”

It's not that Gu Jianglin hasn't thought about these problems, now that time is tight and material resources are limited, it is impossible to have a place for them to experiment.

"So what?" He asked again.

"To be able to draw such a picture, it must be a strange person, and you can find out the answer by asking the person who drew the picture." Wang Zhao said: "The construction methods of these two types of dams are different, and this person must be extremely proficient in water conservancy to be able to draw such a diagram, and to solve such a problem must be handy." ”

Gu Jianglin also thought about it, but Xi Muyun said that she also got this book by accident, and I am afraid that the person who drew the picture will not be found.

So will Xi Muyun, who has this book, be able to find a complete and beautiful solution?

He suddenly felt a little headache.

Wang Zhao smiled, "Now we still have to solve the problem of sediment sedimentation underneath, the sediment is light and fluttering, and the foundation is unstable, so the dam will also collapse." ”

Gu Jianglin nodded, "This project will have to be done in the spring of next year, can you find a complete plan?" ”

Wang Zhao shook his head, indicating that he couldn't do anything, "It's too profound, I can't understand it, this is not a traditional method." ”

Gu Jianglin no longer embarrassed him.

Xu Bu didn't know how long he received a letter from Gu Jianglin, which stated the difficulties encountered in building the dam.

Xu didn't know, now, maybe only with this book Xi Duyun can solve it.

He went to the store to look for Xi Duyun, but the people in the store said that Xi Duyun did not come.

She should be there at this point, but after asking Xu Bu, she didn't know that Xi Duyun hadn't been in the store for a few days.

He went to Xi Duyun's residence again, and learned that she had been tending to her own piece of land.

Xi Duyun knew his intention, but in fact, she didn't know about water conservancy, so she could only read the book.

She hurriedly excused herself, but Xu Bu didn't know and said, "No one can understand it now." ”

Xi Duyun sighed, "I can only study and study. ”

Xu Buzhi hurriedly said, "Then thank you so much Miss Xi." ”

"But in the forefront, although this book is mine, I am not proficient in this aspect, I can only recognize the words on it." Xi Duyun wasn't sure if she could do it, but the book was very detailed, and she could understand many of the modern words on it.
