Her Royal Highness's order was everything to her, and there was no reason to refuse.

"What about yue'er? What needs to be done?" Li Lingyue asked expectantly.

"You? Dig a big hole with a stone first, and I'll use it next," said Wu Zetian.

"Dig out a big pit with a stone?" Li Lingyue said bitterly.

Not to mention the weight of the stone, the soil here is very hard, and it is not a stone that can be dug at all.

"What? Is there anything wrong?" Wu Zetian said to Li Lingyue.

"No, your highness, I'm a weak woman. It's a little hard to do such a job." Li Lingyue said with a smile.

"It's not a big week to work hard. If you want to take a bath, you must force yourself." Wu Zetian said seriously.

"Yes." Li Lingyue had no choice, nodded and began to dig a hole with a stone.

Unexpectedly, the soil was very soft.

"What's going on? Is it the reason for the perennial rain erosion?" Li Lingyue turned her mind and began to work hard.

As time passed, Shangguan Waner came to this side: "Your Highness, the water pipe has been pressed by me with a stone, and now it is particularly stable."

Wu Zetian took a look at the water pipe and pulled it gently.

The water pipe is still.

Seeing this, she nodded: "Wan'er, you did a good job."

"Thank you, your highness!" said Shangguan Waner with a happy face.

"Wan'er, come and help me." Li Lingyue suddenly said at this time.

The soil is very soft. She has dug about nine feet from the stone, but it is obviously far from the requirements of Her Highness.

"Yes." Shangguan Waner agreed, and also picked up the stone and began to dig.

With their concerted efforts, a big pit was soon dug out.

"Well, now insert the water pipe into the pit and cover it with soil." Wu Zetian commanded.

Hearing this, Shangguan Waner immediately looked at Li Lingyue.

"So it is. Your highness is really farsighted." Shangguan Waner chuckled.

Li Lingyue also nodded: "Your Highness is your highness. You can face it calmly wherever you are."

"Well, don't flatter. Time is running out. If it's not well under construction, the immortal will say again." Wu Zetian said calmly.

"Yes!" they promised and began to get busy.

On the other side, Jiang Yichu looked at the backyard and nodded slightly: "do they mind taking a bath in the open air?"

"I don't mind."

Thinking like this, Jiang Yichu took out a white cloth and pulled it into a curtain and smashed it against the wall in the backyard.

Bang, bang.

Two slight sounds sounded, and the white cloth was hung steadily.

"That's OK. The next thing is the water temperature." Jiang Yichu said, frowning deeply.

It's easy to divert water and cover up, but the water temperature problem is not easy to control.

"Hey, it's really troublesome." Jiang Yichu thought for a long time, and only thought of that way.

He went to the back yard and took out some boards and brackets.

After looking at the pipe, Jiang Yichu skillfully inserted the pipe into the support, and then lit the fire.

Whoosh.

The flame was burning and burning.

Seeing this scene, Jiang Yichu nodded: "it's done. In this way, the cold water will become hot after heating. Next, let's see if they're done."

He smiled and walked towards the river.

By the river, Shangguan Waner had difficulty fixing the water pipe into the soil, gently pulled it and nodded slightly: "Your Highness, the water pipe has been fixed by me, no problem."

"Your Highness, there's no problem here," Li Lingyue checked.

"Well, we have lived up to the immortal's expectations this time." Wu Zetian sighed softly.

"Your Highness, Wan'er doesn't understand why the immortal asked us to do these things?" Shangguan Wan'er asked.

"Yue'er doesn't understand either." Li Lingyue shook her head.

"I don't know, but seeing the immortal means to connect the water in the river with this pipe." Wu Zetian frowned and thought for a moment.

"How is this possible?" Shangguan Waner was stunned first, then shook her head.

She didn't believe that the water pipe could suck all the river water into it.

"Your Highness, this seems unlikely?" Li Lingyue also asked.

"Who knows? I'll see what the immortal said later." Wu Zetian also felt some absurdity and smiled gently.

"Are you ready?"

A voice came from a distance. It was Jiang Yichu.

"Back to immortal, I'm ready." Wu Zetian's eyes lit up.

"Immortal, what do you want us to prepare this for?" Shangguan Waner asked first.

As soon as Li Lingyue listened, she also looked at Jiang Yichu.

"Don't worry, don't worry, come and ask me to see what you've prepared." Jiang Yichu said and checked.

When he saw that the water pipe was deep in the river, he flashed with appreciation: "yes, who came up with this method? Yes!"

"This method not only fixes the water pipe, but also ensures that the river always surrounds the water pipe. Good, good."

"Immortal, this is the way your highness came up with." Shangguan Waner asked for credit.

"It's Xiaotian. I don't see you're so smart." Jiang Yichu flashed a trace of surprise.

"Immortal, your Highness's talent is from ancient times to modern times. It will never leak out until the critical moment." Li Lingyue smiled and explained.

"Well, it seems that I underestimated you." Jiang Yichu nodded slightly.

"Immortal, can you tell me what it means to get this water pipe now?" Shangguan Waner asked.

Li Lingyue and Wu Zetian looked concerned together.

"This pipe is used to absorb water and suck the water from the river into it." Jiang Yichu said.

Although the three of them had guessed about it, they couldn't help being surprised when they heard that it was true.

"Immortal, can this pipe really suck out all the water in the river?" asked Wu Zetian.

"Immortal, how do you suck? There's nothing here." Shangguan Waner wondered.

Li Lingyue frowned thoughtfully and didn't speak.

"Silly, I want you to see what principle is." Jiang Yichu turned his eyes and walked towards the inner room.

The three looked at each other and followed up one after another.

In the backyard, Jiang Yichu pointed to the front: "do you see the white wooden house? That's the bathing place I made for you."

"... immortal, you're a little fast..." Shangguan Waner didn't know what to say.

Li Lingyue was also speechless.

How long has it been since the immortal created a wooden house out of thin air?

It's amazing.

Wu Zetian's eyes twinkled with starlight: "the immortal is worthy of being an immortal. The means are not understandable to us."

Jiang Yichu had been used to this scene for a long time. He waved his hand gently and went to the iron wheel finger in the distance.
