After being married off by my younger sister, I took care of the sickly prince

Liu Huier did not refuse Wang Ma's kindness and was obediently sent back to her room by Wang Ma.

In the restaurant, Fu Ming was no longer as interested in the snacks on the table as before.

Jiang Yun stood up and wanted to pour another cup of tea for Fu Ming.

Fu Ming waved his hand and said, "No, I haven't been to Chong'an Palace for a long time. I want to walk around the palace. Why don't you accompany me for a while?"

Jiang Yun put down the teapot and said, "Yes!"

The group arrived at the back garden of the palace.

But there are not many flowers here. They are all medicinal herbs planted by Jiang Yun. They have just sprouted and look very desolate.

Jinzhong stared at the unrecognizable back garden in astonishment, then turned to look at Uncle Fu, his eyes full of confusion.

Uncle Fu looked at his nose with his eyes, and his heart with his nose. He looked at the sky and the earth, but he didn't look at Jinzhong.

Jiang Yun also stood behind somewhat awkwardly.

They had been following the emperor all the way. Seeing the emperor walking forward in high spirits, she was too embarrassed to run up to stop him, which led to the current situation.

When everyone was silent, Fu Xuanyu smiled and said, "Ayun is thrifty. In order to save money on medicine, he planted medicinal herbs in the back garden."

When Fu Ming heard this, he immediately laughed.

He turned to Jiang Yun and praised her, "Great! That's a good idea! This is much better than those rare flowers and plants. I hate those rare flowers and plants the most."

Jinzhong: ???

He still remembered that the emperor had specially summoned all the concubines in the harem to appreciate a pot of rare green chrysanthemums.

How much the emperor loves flowers and plants, how could he not know?

Now you even say you don’t love me anymore.

Jinzhong was the first one who didn't believe it!

but……

Jinzhong glanced at the prince and princess, and understood in his heart that the emperor doted on them very much.

If Prince Chong'an's leg is really cured, I'm afraid the emperor will pass the throne to Prince Chong'an.

Although Prince Chong'an and the Crown Prince were both born to the Queen, their personalities were very different. Anyone with a discerning eye could see that the Emperor favored Prince Chong'an more.

Later, Jiang Yun led the way, explaining what medicinal herbs were planted around and what their effects were.

As they talked and listened along the way, they soon made their way out of the back garden and arrived at the public washroom of the palace.

This was built by Jiang Yun and his workers to facilitate emergency response for the people in the mansion.

Fu Ming heard the sound of water splashing from inside, looked at it in confusion and asked, "What is going on in here?"

Fu Xuanyu slid his wheelchair forward and said, "In reply to Father, this is the bathroom, specially used for emergencies."

Fu Ming frowned and asked, "What was that sound of water just now?"

"That's the sound of a toilet flushing. How about I take you inside to take a look?"

Fu Ming nodded. He was already very curious, and after Fu Xuanyu said it was used for 'going to the toilet', he became even more curious.

Jinzhong was also very curious and couldn't help but stick his head out to take a look.

Jiang Yun winked at Uncle Fu, who stepped forward and gestured to Jinzhong, "Eunuch Jinzhong, I'll take you in to have a look."

Jinzhong was delighted and nodded, saying, "Okay."

When I walked in, I found that there were actually separate areas for men and women.

Uncle Fu took Jinzhong directly into the men's restroom.

After entering, there were compartments inside. Uncle Fu first explained it to Jinzhong, and then Jinzhong walked into a compartment. After finishing, he pressed the flush button, and a "splashing" sound instantly came from inside, and then water flowed to wash away the filth.

When Jinzhong came out, Fu Ming and Fu Xuanyu were already outside chatting about the bathroom.

When Fu Ming learned that this was built by Jiang Yun again, he looked at Jiang Yun with even more loving eyes.

He said, "Yun'er, can the palace build these together?"

Jiang Yun nodded and said, "Of course. And His Royal Highness the Crown Prince has already ordered two sets for the Emperor and the Empress from our furniture store. Tomorrow, His Royal Highness the Crown Prince will bring the craftsmen to the palace to install them for the Emperor and the Empress."

Fu Ming nodded and said with satisfaction: "I am very pleased that Chuan'er is so filial. But I want to install this in every palace, and I also want to build a few public toilets like yours in the palace."

Jiang Yun considered and said, "The ones in the various palaces are easy to deal with, but the location of the public restrooms needs to be considered in conjunction with the bird's-eye view. Or, Father can just circle the location, and Ayu and I will ask the Ministry of Works to build it."

Fu Ming nodded and said, "Okay! Tomorrow, I'll have someone from the Ministry of Industry look for you at the furniture store."

Jiang Yun's eyes flashed with a flicker, and he said with an embarrassed look: "Father, actually, my daughter-in-law has another idea, but I don't know whether I should say it or not."

Fu Ming was happy at the moment. He waved his hand and said, "Speak! No matter what you say, I will grant you innocence."

Jiang Yun then spoke, "I believe that Father has also noticed that the water flow in the bathroom is unstable. In fact, my daughter-in-law has a way to make the water flow more stable and make it more convenient for the people to get water."

Fu Mingwei frowned, not knowing what Jiang Yun wanted to say, but he could tell that the method Jiang Yun mentioned was a good thing that would benefit the people.

He asked, "What's the solution?"

Jiang Yun took a step forward and gestured to invite them: "Father, please follow your daughter-in-law to the front."

Fu Ming nodded, and the group quickly followed Jiang Yun to the center of the garden.

Jiang Yun walked forward and moved a few potted trees to reveal what was inside.

There stood a copper rod, curved at the top, with a short horizontal bar lying flat on top.

Fu Ming looked at the strange-shaped copper rod and didn't understand why Jiang Yun brought everyone here.

Is there something special about that copper rod?

Everyone saw Jiang Yun walk forward, pinch the top short horizontal bar with two fingers, gently rotate it a few times, and then let go.

Then a "whoosh" sound came from the copper rod, and a stream of water flowed out from the hole in the copper rod.

There was a loud "whoosh" that startled everyone.

Then Jiang Yun stretched out two fingers again, pinched the short horizontal bar at the top, and gently rotated it in the opposite direction a few times. As she rotated, the water flow became smaller until it disappeared.

Although Fu Xuanyu had been in the palace all the time, he had no idea when Jiang Yun had come up with such a magical thing.

He looked at Jiang Yun with anticipation, waiting for her explanation, just like the first time Jiang Yun took him and Zhufeng to see the toilet and shower.

Jiang Yun pointed at the copper rod and said, "Father, this is the solution your daughter-in-law wants to talk about. This thing is called a water pipe. Just turn this switch and water will flow out. However, these pipes need to be buried underground, and the other end needs to be connected to a water source so that water can flow."

Fu Ming looked at the copper rod and murmured, "Tap water, water pipe. What a great name!"

He took a deep breath, turned his head to look at Fu Xuanyu and said, "Ayu, you have married a treasure!"
