Hearing Ye Lan'er say this, Yu Feiyuan was slightly disappointed and relieved at the same time.

Knowing that Gu Qingchen was close at hand, she suddenly had a feeling of homesickness, a little helpless and a little timid.

She smiled and said, "It's okay Lan'er, maybe it's because you're tired from the journey, so your energy is a little lacking." ”

"Sister...... Although I can't find the exact location of Brother Gu, I followed his tracks, and it was indeed right in this Xiyi King City. ”

Yu Feikite smiled slightly: "Okay, then let's stay here for the time being, and it's not too late to find him slowly." ”

Ye Lan'er nodded: "Okay sister." That...... I went back to my room to rest. ”

Ye Lan'er was so restless that she almost ran away from Yu Feiyu's room.

Back in her room, she fidgeted and restlessed.

It seems that Gu Qingchen is not in any danger at all, and he has become a princess and a concubine, and he has long left the jade flying kite behind. and that old friend Murong Ke, who is attached to him, I'm afraid he can't think about it at all.

Thinking of this, Ye Lan'er was furious and clenched her fists in her hands. With this damn Gu Qingchen, he was discovered by Sister Fei Kite that he was so affectionate, how did Sister Fei Kite accept it!

Be sure to find a way to get him the punishment he deserves!

In order to get through the trick and not let Yu Feiyuan become suspicious, starting the next day, Ye Lan'er began her journey of pretending to be sick.

In order to let Ye Lan'er "recuperate with peace of mind", Yu Feiyuan bought a small mansion in the city after several negotiations, and the three of them moved in.

Although they brought a lot of coils on the road, they were immediately a little stretched after paying for the house.

Yu Feikite finally diverted her attention from Gu Qingchen and began to worry about her livelihood.

Ye Lan'er locked herself in the room and didn't go out for three days.

When she finally opened the door, she had several pieces of straw paper in her hand and joy on her face.

"Sister! Oh my God! Come and see! ”

Yu Feiyu, who was picking vegetables, and Mao Shuntian, who was practicing the piano on the side, heard Ye Lan'er's voice and came over.

Ye Lan'er spread the five pieces of paper in her hand on the ground and displayed: "Look! ”

"What is this?" The jade flying kite looked at the strange shapes outlined by the various lines on the papyrus, and did not know why.

Ye Lan'er's face was full of pride: "This, it's a steam engine!" Hahaha! The day of our prosperity is coming soon! ”

Based on what she had learned during her nine years of schooling, Englishman Watt improved the steam engine, marking the beginning of the first industrial revolution.

The steam engine solves the power problem of industrial development and has an extremely far-reaching influence and great role.

And its principle Ye Laner is also very clear, that is, to use steam to drive the piston to move and generate kinetic energy.

With a little impression and her own bold ideas, she was stunned to draw the drawings of the steam engine.

Now all you need to do is find some blacksmiths, make the steam engine for yourself according to the drawings, and then ...... And then there's so much that can be done!

Ye Lan'er was beaming with joy, seeing the confused faces of Yu Feiyuan and Mao Shuntian, she explained: "This thing is equivalent to a donkey pulling and grinding donkey, as long as we find a blacksmith to do it for us, we can do a lot of things!" Cultivated land! Chungmi! Grinding noodles! And so on and so forth! ”

Yu Feikite spread his hands: "However, there is not a single blacksmith in the whole country of Xiyi, because they don't understand iron-smelting technology at all......"

"Huh?" Ye Lan'er opened her mouth wide, "How can this be!?" ”

Yu Feiyuan put away the drawings on the ground: "The Xiyi Royal Court spends a lot of gold and silver every year to buy iron tools from Yunlan Kingdom. Iron is more expensive than silver. ”

She stood up and handed the drawings to Ye Lan'er: "Lan'er, your illness is not well yet, don't worry about money." Keep it in peace.

This ...... yours Steam engine...... The idea is good, and it will definitely be realized in the future. ”

Ye Lan'er took the drawings and hung her head dejectedly.

Only then did she realize that according to the smelting technology at this time, even if a blacksmith was found, the steam engine might not be made.

His steps are a little big, even if he is not a man, he is.

She went back to her room, and before closing the door, she glanced at the jade flying kite, and felt very sad.

These days, Yu Feikite is simply an old mother, cleaning the huge house, washing and cooking, and taking care of her own fake sick number.

Originally, I thought that I could make a small profit by stealing future inventions by myself, at least adding a few servants to the family. But I failed so easily, and I was really depressed.

She returned to the room, thinking of Gu Qingchen who was in her arms, and her heart became even angrier.

She cleaned up, changed into men's clothes, disguised herself a little, and slipped out of the house.

After walking a few blocks, Ye Lan'er came to the door of the princess's mansion.

Actually standing in front of the princess's mansion, Ye Lan'er found that it was more luxurious and majestic than the last time she had seen it, and it was more golden and shining.

is worthy of being the eldest princess of the old Xiyi King, and this princess's mansion is not even comparable to the prince's palace.

Ye Lan'er stood on the street opposite the princess's mansion for a long time, and found that the princess's mansion was always closed, and it didn't seem to be a hospitable person. She originally wanted to wait here, but it seemed that there was no hope for her to meet that lucky Gu Qingchen.

Just as Ye Lan'er turned around to leave, there was a sudden "boom", and a loud noise came from the princess's mansion.

The people on the street had never heard such a loud noise before, and they were all frightened and crouched on the ground with their heads in their hands.

Ye Lan'er felt that the ground shook three times, and she couldn't believe that the princess's mansion would make an explosion!

Yes, yes, it was definitely an explosion. Only an explosion can have such power.

This princess's mansion is definitely problematic.

Ye Lan'er took advantage of the panic on the street and the guards of the princess's mansion to panic, so she spotted a gap and climbed over the wall to enter the princess's mansion.

The subordinates of the princess's mansion all ran in one direction, and Ye Lan'er took the opportunity to get into the subordinate room, changed into the clothes of a small maid, and ran over.

Everyone gathered in front of Gu Qingchen's study. But no one dared to go in.

Ye Lan'er saw that the windows of Gu Qingchen's study were shattered, and white smoke was emitting from inside.

The chief butler shouted outside the door: "Master Horse!?" Horse Lord? How are you, alright? ”

After a while, the eldest princess, who called herself "Qing'er", came over with the support of her maid.

She was a little angry: "What are you doing in a daze? Why don't you go in and save the pony! ”

The little servants hesitated, and the big butler said, "Your Royal Highness, Lord Ma never allowed us to enter his study......

The princess's angry eyebrows were raised: "When is this!" You! You! You! Let me in! Look how the pony is doing! ”

Ye Lan'er originally lowered her head and shrunk her neck to minimize her sense of existence, but just now she just looked up at the appearance of this princess, and she named her.

This damn Qing'er, it's a pity that I don't know what her surname is, otherwise Ye Lan'er would definitely not want to call him so affectionately......

Obviously, he didn't even dare to go in, but he had to assign them subordinates.

However, Ye Lan'er was very curious about what Gu Qingchen was doing in the room, she hunched over, followed behind the other two servants, and pushed the door into Gu Qingchen's study.

Gu Qingchen's study was very large, and at this time, he was not in front of the bookcase where he had seen him before, but in a place similar to a secret room inside.

At this time, the secret room could no longer be seen in its usual layout, and all sides were covered with black dust, and the tables and chairs were not spared.

Gu Qingchen, who was dressed in white, fell to the ground on his back, his face was black and unconscious.

The two servants were frightened, Ye Lan'er took a step forward and tried Gu Qingchen's snort: "There is still qi, but he fainted, you come to help me help him up." ”

The servants helped Gu Qingchen up and put him on the chair according to Ye Lan'er's instructions, and then they watched in amazement as Ye Lan'er took a big mouthful of water, "Poof-" and sprayed it all on the face of the tall horse master.

The black ash on Gu Qingchen's face was sprayed away, revealing half of his white face.

He opened his eyes, looked at Ye Lan'er, then at the other servants, and then at his own messy study, and sighed.

With the help of the two servants, he stood up, patted the dust off his body, and walked out.

"Master Horse, what the hell is going on here, the earth just shook the mountain, and the surrounding residents are terrified." Ye Lan'er asked before he walked out the door.

Gu Qingchen didn't look at her, and said dejectedly: "Hey, the experiment failed, what else could it be?" ”

Ye Lan'er chuckled in her heart, the experiment failed?

People in this era also understand what an experiment is? This Gu Qingchen is really suspicious......

Ye Lan'er had thousands of questions in her heart, but she couldn't ask anything, she hung her head and followed behind Gu Qingchen and walked out of the door of the study.

Everyone outside the door was relieved to see Gu Qingchen walking out safely, but when they saw that his entire face was blackened, and his white clothes were like a dirty rag, they all covered their mouths and laughed.

Celestia coughed, and everyone was immediately silent. Some people couldn't help but laugh and hiccup.

Gu Qingchen walked to the eldest princess and reached out to hug her, but when he saw that he was filthy, he retracted his hand again.

"Princess, just laugh at them, don't be angry. I won't take it to heart, and one day, I will succeed. ”

"Nameless, you're always so kind-hearted, don't let these lowly people kick their noses in the face. Are you okay? ”

Nameless?

Ye Lan'er frowned when she heard the eldest princess's address to Gu Qingchen.

She stretched out her elbow and poked the little guy next to her: "Hey, our colt, what's your surname?" ”

The little guy turned Ye Lan'er white: "When did you enter the mansion?" I don't know, our concubine is a famous and nameless, the person our emperor values the most! ”
