Wu Ning didn't care much about the matter of rewarding food.

However, through this incident, he got a closer understanding of the contradiction between the gate valve and the old lady, and also understood the root of the problem.

It's just money!

Wu Ning knew this, and his mood immediately improved.

Before, the old lady gave him the task of smoothing the Chang'an gate valve, Wu Ning didn't have a root, but now he has a clue.

Money is easy to do!

Lao Tzu is very good at it, okay?

It is in response to a sentence of poisonous chicken soup in later generations: 99% of the things in this world can be solved with money, and the remaining 1%....

Need more money!

Putting this idea aside for the time being, his priority now is to solve the problem of Chang'an's sewerage.

Only when the water is solved, the problems on the ground can be followed up and solved, and then the door valve is a matter of the gate.

Take it one step at a time, no rush.

But it's ...... to go into the water

Old Madam Wu did send two people, but they were two mallets.

Not to mention the sewerage of a city with a population of two million, these two people couldn't even figure out the original sewerage system of the old Chang'an City.

What makes Wu Ning feel a little desperate?

But what can be done? A dead horse is a live horse doctor, at least these two people are stronger than him, and they still have to be used.

Again, step by step, if you can't get a new sewer system, then first understand the old sewer system.

If you can't figure out the old sewer system, then give them time and let them study it little by little, and they can't be in a hurry.

"Where's Tang Jun?"

When he arrived at the Yamen of the City Construction Supervisor, Wu Ning first looked for Tang Jun.

The scribe said: "It seems to be in Deputy Supervisor Cheng's office." ”

Yes, Wu Ning is bitter, Lao Tzu is working hard here, those three goods are good, chatting and farting all day long, and they don't even have anything to do.

Kill Cheng Boqing's office.

Sure enough, Tang Jun, Cheng Boqing, and the eldest grandson Yuanji were chatting there.

Wu Ning first said to Tang Jun: "Go to the library to find me a few pictures, the repair drafts of the water in the city over the years." ”

Tang Jun nodded, didn't speak, and went in person.

After a banquet in the Crane Tower that day, the arrival of these three goods did not make trouble for Wu Ning.

But after all, they are all young people, and they are full of anger, and Xu is heart can't let go of the pimple, but they are all awkward.

Just like Tang Jun, he is the secretary, the key to the library, Wu Ning asked him to find it, he didn't discount it, he went to find it in person, but he didn't want to say more to Wu Ning.

......

As soon as Tang Jun left, Wu Ning simply waited in Cheng Boqing's office, staring at Cheng Boqing and the eldest grandson Yuanji.

After being so stiff for a long time, Wu Laojiu really felt embarrassed, and said to Cheng Boqing: "What? How long has it been, and it's still awkward? ”

"Cut!!" Cheng Boqing pinned his face to the side, "How long?" How long can I remember! ”

glanced at Wu Ning, "Despicable villain!" Pure out of the shadows! ”

"Hahaha!"

Wu Ning was happy, and said in his heart, I, Wu Laojiu, am not a good person!

Cheng Boqing was okay with everything else, mainly because he was on guard that day, and he still let Wu Ning get a pit, which was a little unacceptable.

How so?

It's hard to prevent!

Guarding against Taiping, guarding against Mu Ziqi, and guarding against his two big masters, the result is ......

There are also Li Bao'er and Wu Chongxun in this goods!

In particular, if he is careful and careful, he will still fall into a big pit.

It's no wonder that Cheng Boqing can be happy.

"Alright!" Wu Ning said slowly, "It's all old men, it's almost there!" I didn't kill your whole family, is there such a big hatred? ”

Raising his eyebrows, "I'll invite you to dinner and drink in the evening, and that's the end of the matter, how about it!?" ”

"Don't go!"

Thinking about it, Cheng Boqing's eyes widened, not to mention that it was okay to eat and drink, and he was even more angry when he mentioned it.

"Love doesn't go!"

Wu Ning said that, and glanced at Cheng Boqing, "You are really a Nine Heavens Xuannu, a stunning beauty!" Why does Lao Tzu have to be coaxed? “

As he spoke, Tang Jun had already returned, holding a stack of drawings in his arms, all of which were drawings of Chang'an Water Conservancy over the years.

Wu Ning no longer paid attention to Cheng Boqing, took the drawing, and found a place in this room to look at it.

In fact, there is nothing to find, Chang'an is repaired every year, but there are not many changes every year.

Wu Ning also found a few clearly marked and distinctive photos from them, and used them as a reference for the two fools from Luoyang.

Cheng Boqing didn't take it seriously at first, so he let Wu Ning rummage around there.

However, after a few peeks, I also saw what Wu Ning was going to do.

Stuffy pretending to do things, hesitated for a while, and finally popped out a sentence: "Xianheng four years...."

"Huh?" Wu Ning was stunned, "What Xianheng four years?" ”

Cheng Boqing didn't raise his head, "Looking for Xianheng's four-year city map." ”

“......”

Wu Ning was stunned, and then rummaged through a pile of drawings in astonishment.

In the fourth year of Xianheng, that is, in 673 A.D., it has been twenty-six and seven years ago.

It took Wu Ning a lot of time to dig out an old manuscript that had turned yellow from the pile of artworks.

When I looked at it, my brows couldn't help frowning, and... Nothing special, right?

There are almost no changes from the current artwork, and due to age, due to the dampness, some places are even more obscure.

I can't help but ask, "Is there anything special about this?" ”

When Cheng Boqing heard this, he was a little impatient.

Why is this grandson's understanding so bad? The eyes were not very good, and he reminded angrily: "The lower right corner!" ”

At this time, Tang Jun also spoke, but he was not as impatient as Cheng Boqing, and explained to Wu Ning.

"The current Chang'an is under the water, which was built in the fourth year of Xianheng. Since then, it has been repaired and maintained, and it has not changed much. Therefore, the artwork of Xianheng for four years is the first draft. ”

"The name of the subordinate officer who designed this picture is marked in the lower right corner."

“！！！”

Wu Ning was overjoyed when he heard this,, there are two of these goods!

didn't care about anything else, so he hurriedly looked at the lower right corner of the drawing, only to see that there was indeed a person's name there, and there were traces of Yin Hong's seal.

Although it is a little vague, I can still see what is written.

Wu Ning looked at it, and there was a name quietly written on it that surprised him-

Deputy Supervisor of Chang'an City: Wang Miao.

"Wang Miao!?"

Wu Ning was suddenly shocked, isn't Wang Miao Wang Congjian's father, Princess Xuancheng's concubine!?

Wu Ning raised his head and couldn't believe it, "Wang Miao understands water conservancy?" ”

I saw Cheng Boqing Erlang's legs, and said leisurely, "Before the history of assassination, I really understood it very well." Now? I can't tell! ”

"!!"

Wu Laojiu was so excited that he directly burst into foul language.

Grab the old artwork and run out, it was really hard to find nowhere to find the iron shoes, and it took no effort to get it. Who would have thought that Wang Congjian and his father would still have these two sons.

After running out a few steps, Wu Ning turned back again.

This time, thanks to Cheng Boqing and Tang Jun, Wu Ning forgot to thank others.

It's just that Wu Laojiu was a little excited, and let this matter get stuck with him for two months, can he not be excited?

First rushed to Tang Jun and hugged Tang Jun, "Thank you, brother!" ”

turned around and went to hug Cheng Boqing again.

"You, you, you...... Stay away from me! ”

frightened Cheng Boqing and shrank directly into the corner.

I don't see it, this grandson won't be a good man, right?

He hid, Wu Ning did it, and before leaving, he said: "This situation has been recorded, and there will be a retribution!" ”

......
