When I traveled through time, I relied on the system to lie flat all the way

After Gu Chenrui finished speaking, he stood up and left, while Lin Yun twitched the corner of his mouth and whispered: "Miss Li would not do this."

The housekeeper looked at Lin Yun and asked doubtfully: "Lin Yun, what did you say?"

"I didn't say anything. Let's go, Uncle Xu, let's go see the future princess together."

When Uncle Xu heard this, he also laughed, but looking at Gu Chenrui's anxious back, his brows furrowed slightly.

Lin Yun saw this and asked, "Does Uncle Xu think that a peasant girl is not worthy of a master?"

When Uncle Xu heard this, he shook his head, "As long as the prince likes her, then she will be the princess in my heart. However, I am worried that the Holy Emperor will not agree. When the time comes..."

When Lin Yun heard this, the corners of his mouth curled up, and he whispered: "Uncle Xu, I forgot to tell you something."

Butler Xu: "What's the matter?"

Lin Yun: "The Emperor likes this Miss Li very much, so what you are worried about will probably not happen."

As soon as these words came out, Butler Xu exclaimed: "What?"

Seeing Gu Chenrui turn around, Lin Yun quickly covered Butler Xu's mouth, "Keep your voice down. If the master finds out that I'm talking nonsense, I'll be in trouble."

Butler Xu nodded excitedly, took off Lin Yun's hand, and said anxiously: "I'll ask the cook to prepare some pastries for Miss Li, and by the way, there are also fruits."

Lin Yun's mouth curled up when he saw Butler Xu anxiously heading towards the kitchen as he spoke.

Seeing Lin Yun following him, Gu Chenrui asked doubtfully, "What did you tell Butler Xu to make him so happy?"

"My subordinate told Uncle Xu that the prince was anxious to see the princess, and he was so happy when he heard it."

When Gu Chenrui heard the word "princess", the corners of his mouth curled up and his pace quickened a lot.

When he came to the front hall and saw that it was Li Sirou, a rare smile appeared on his face.

Lin Yun looked at his master's smile and was slightly stunned.

He has been with his master since he was a child. He has never seen such a smile since the death of the Queen Mother. He did not expect to see his heartfelt smile again today.

When Li Sirou heard the footsteps, she turned around and met Gu Chenrui's smile. Seeing him smiling so happily, she was slightly stunned.

Gu Chenrui: "Xiao Rou'er, why did you come from the main entrance?

Didn’t I tell you that someone is staring at the door..."

Before Gu Chenrui could finish speaking, Li Sirou asked, "Are you happy?"

Gu Chenrui nodded, "Happy, but..."

Li Sirou knew what Gu Chenrui was worried about, but she couldn't bear to see him being so cautious.

"Gu Chenrui, this is the first time that I have come to your Prince Chen's residence openly and openly, and you don't want to show me around?"

When Gu Chenrui heard this, he grinned. Now that the matter is over, let's just let it take its course.

After thinking about it, Gu Chenrui nodded and said, "Let's go, I'll show you around."

As a result, the servants of Prince Chen's Mansion saw that the normally stern Prince was taking a girl around the Prince's Mansion with a smile on his face.

Li Sirou walked around for a while and then asked: "Is there no maid in your house?"

Gu Chenrui: "Yes, but they are all elderly nuns."

Li Sirou: "Don't you have a young maid?"

Gu Chenrui shook his head, "No."

When Li Sirou heard this, she smiled and said, "Are you a good person or are you a little afraid of women?"

When Gu Chenrui heard this, he coughed lightly and said, "I'm not afraid of women, I just find them troublesome."

After saying that, he was afraid that Li Sirou would ask anything else, so he said, "The things that Brother Huang gave you have arrived. Why don't you go and take a look?"

Li Sirou nodded, looked at Lin Yun and said: "Lin Yun, find Sun Xuehu."

Lin Yun nodded and went to Zou Gong's yard.

Gu Chenrui took Li Sirou to his yard. When he saw the things in the yard, Li Sirou was stunned for a moment.

In front of you is a very large iron bucket. The shape looks a bit strange. Half of it is made of iron and the other half is covered with mud.

But Li Sirou could tell at a glance that this was a simple version of a solar water boiler.

When she stepped forward to check, she discovered that the mud-like substance was actually quartz sand.

“I didn’t expect to find quartz sand.”

When Gu Chenrui heard this, he turned to look at Li Sirou and asked doubtfully: "What is quartz sand?"

When Li Sirou heard Gu Chenrui's question, she realized that she had just spoken out what was in her heart.

She looked at Gu Chenrui and said, "Quartz sand is a stone with good heat absorption effect.

After your brother smashed it and spread it on the iron bucket, when the sunlight shines on the quartz sand, it will heat the water in the iron bucket. In this way, a simple version of the solar water heater is completed. "

When Gu Chenrui heard Li Sirou's words, he was stunned for a moment, frowned and said, "Xiao Rou'er, what do you mean, this ugly thing is used to boil water?"

Li Sirou nodded. Seeing that Gu Chenrui still didn't understand, she asked, "Is there water in here?"

Gu Chenrui nodded, "Brother Huang wrote and said, just let me put this in the yard, put water in it and wait for you to come."

By the way, there is also this. Brother Huang said that you will know after reading it. "

Li Sirou looked at the simple device diagram drawn above and laughed, thinking to herself, as expected of a researcher, he was very thoughtful.

After looking at it, she pulled Gu Chenrui to the switch. When she saw the leaky faucet, the corner of her mouth twitched.

No wonder she said in the letter that this thing was very simple and she needed to make some minor modifications.

Li Sirou ignored the floor and let Chen Hanxiang get the basin. Then she turned on the hot water faucet and saw steaming water flowing out of it.

Seeing this, Gu Chenrui probably understood a little bit, but he still didn't understand. What did Xiao Rou'er want with this thing?

Seeing his expression, Li Sirou said, "Let's do this. I happen to be here today. I'll ask Sun Xuehu to install it for you later."

After finishing speaking, seeing Lin Yun coming with Sun Xuehu, he said: "You stay in the front yard today. When I finish, I will send someone to call you."

"Xiao Rou'er, can I stay here with you?"

"No, if you stay here, what surprises are there? If you don't worry, let Lin Yun stay and watch, but you have to get out." After saying that, Gu Chenrui was pushed out of the yard.

As soon as the courtyard door was closed, Li Sirou turned around and drained all the water inside. Then she looked at Sun Xuehu and said, "Cut the previously reserved position according to this size."

Sun Xuehu nodded and went upstairs with Lin Yun.

Taking advantage of their absence, Li Sirou bought a new faucet from the mall.

Since there was no rubber ring, the Emperor used cloth instead.

When I sent those books to him, I had already told him in disguise that I had a mall.

No, looking at the various hole positions and device diagrams reserved for her in advance, it was obvious that she wanted to improve herself.

Li Sirou originally wanted to lend him a hand to make the solar water heater he was going to install in the future justifiable, but unexpectedly, he found quartz sand and enhanced its heat absorption and heat preservation capabilities.
