I've been reborn, who still wants to be a cowardly little white flower?

Looking at the device in the courtyard, Xie Yunxiao was the first to react. He rushed to the device, looked at the mud and sand inside, pointed at it and asked Jiang Yuan excitedly, "Is this a simulated river?"

After he said this, the others also reacted. Qu Ying also slapped his head and said with sudden realization, "How could I forget that day when you asked me about the Black River, and then you started to do these things. It turns out that you made something that imitates the river. What is this for? Are you trying to find a way to control floods?"

Jiang Yuan nodded, pulled Jiang Huai to the device, and picked up a piece of iron that was just the right length to fit on the wooden river channel.

"Brother, I want to do an experiment. I want to build a weir in the middle of the river. This way, the upstream river water will be blocked by the weir, and the flow will slow down and the water level will rise.

The water in the downstream flows fast, but it can narrow the range of the river flow. During the rainy season, the water level in the upstream rises, but it can be resisted and there will be no floods that submerge the downstream villages.

However, the water flow will carry the silt, and the accumulation of silt will cause the water level to rise, and eventually reach the level of the weir. At that time, the entire downstream area will be lost. "

Jiang Huai nodded in agreement. "So, you asked me to come here because you want to work together to find a solution to the problem of silt accumulation?"

“Well, of course, building a weir is only my initial idea, and the results I’ve seen so far on this small device are pretty much what I expected.

I just don’t know whether it can be realized, and whether there will be other changes in the future.”

In her previous life, Jiang Yuan knew about the Dujiangyan Irrigation System built two thousand years ago. It used this principle to control floods, but she didn't understand it thoroughly enough.

She was not majoring in architecture, but after visiting Dujiangyan, she had some understanding of it and could roughly anticipate the hidden dangers. However, she really couldn't remember how to solve them.

However, Jiang Yuan thought that since the ancients two thousand years ago could come up with a way to build such a magnificent Dujiangyan, the people here must also be able to possess such intelligence and talent.

Besides, she has already solved the most difficult and important creative problem. Many things are not impossible to do, but unthinkable.

After Jiang Yuan finished speaking, the four young masters who came all fell into deep thought.

Jiang Huai immediately decided that he would personally monitor this experiment. Whether the mud and sand accumulated, the degree of accumulation, its relationship with the water flow, etc. would all require a period of experimental observation.

Xue Yangling interrupted Jiang Huai and took the initiative to say, "Hey, Brother Zichang is about to take the Spring Examination, so we can't waste too much energy at this time.

Anyway, it's just observation and recording, and most of the time is spent waiting, so I can do it.

I'm close by, and Yun Xiao isn't that busy with work lately. I think I can ask a friend to help, he must be particularly interested."

Jiang Yuan thought of the name in his mind, Lu Chuan.

Xie Yunxiao and Xue Yangling thought of the same thing and said in unison, "Lu Chuan."

They are all good friends, and they must be aware of Captain Lu's work on flood control. Perhaps Lu Chuan will follow in his father's footsteps and will also be interested in this.

But after the discussion, Xue Yangling looked at Jiang Yuan. This idea was Jiang Yuan's. Perhaps she wanted to make a contribution by this and pave the way for her brother.

If they participated, according to Jiang Huai's character, he would definitely not take all the credit. They had no intention of snatching it away, but they didn't know what Jiang Yuan would think.

Jiang Yuan raised her eyes and saw Xue Yangling looking at her, then glanced at the other three people, and smiled helplessly, "Did you gentlemen underestimate me?

If I had wanted to keep it to myself, I wouldn’t have brought you guys to see it.

The people's affairs are important matters that cannot be delayed for even a moment. I wish more people could come up with solutions so that we can take care of it tomorrow."

Xie Yunxiao clapped his hands vigorously, walked to Jiang Huai and patted him on the shoulder, "Brother Zichang has a good sister with an open mind, Sister Jiang Er, I admire you."

"Thank you for the compliment. I'll give you the key to the front door. I don't care how you arrange things here. Just don't tear down the house."

As he spoke, Jiang Yuan threw a bunch of keys, which was caught by Xie Yunxiao. Without stopping for a moment, he said something to the others and left quickly to make arrangements.

They don't care about the credit, but they can't let others destroy it or take the credit away, otherwise they will feel very upset. So they have to arrange for trusted people to protect this courtyard.

"An An..." Jiang Huai called Jiang Yuan softly with a trembling voice.

Jiang Yuan smiled at him, and this smile made him feel extremely at ease.

It has been half a month since Jiang Yuan started selling incense. The news has spread among the ladies of high rank, and the maids in the palace have visited the Marquis's residence twice.

The eldest princess often received invitations, either from the palace or from some lady, and without exception, they all asked about incense.

Jiang Yuan felt that he was suffering from anemia from all the blood he had dripped from making incense these days.

Qin Yunzheng suddenly visited the Jiang Mansion. When Jiang Wan heard the servant's report, she happily changed her clothes and prepared to welcome Qin Yunzheng.

But as soon as Qin Yunzheng entered the yard, he stared at her with a cold gaze. Jiang Wan, who was smiling, was stunned for a moment. Her expression became serious and she spoke cautiously, "Prince, what's wrong?"

Qin Yunzheng flicked his sleeves, snorted, and looked at the servant beside him with sharp eyes.

The servants retreated tactfully. Jiang Wan took the initiative to step forward, took Qin Yunzheng's arm, and wanted to act coquettishly, but was pushed away by Qin Yunzheng.

Jiang Wan staggered and almost fell. She really didn't understand what was going on.

Qin Yunzheng looked at her and said coldly, "Didn't you say that Yun's daughter would no longer make incense?"

Jiang Wan was confused and answered subconsciously, "Yes, Yun Shi swore personally that she would never make incense again in her life. My whole family can prove this, and my father can prove it too."

"Then the Yun family's incense recipe is also destroyed?" Qin Yunzheng gritted his teeth.

Jiang Wan nodded quickly, "Yes, my father saw it with his own eyes. She threw the incense recipe into the brazier and burned it. My father ordered people to rescue it, but the recipe was already burned."

Jiang Wan suddenly remembered something, took two steps forward, and grabbed Qin Yunzheng's sleeve, "But, but my second sister must know the incense recipe. They are Yun family girls, so they must remember the incense recipe by heart.

I have told the prince all of this. Our plan is to let Jiang Yuan reveal the incense recipe himself."

Qin Yunzheng grabbed Jiang Wan's neck fiercely, and kept exerting force. Jiang Wan was finally scared. Her face was full of fear, tears welled up in her eyes, and she uttered two words incoherently, "No...don't..."
