"Captain Li stays!" An excited and somewhat unexpected voice sounded behind Li Xiu.

As the so-called fear of something, Li Xiu wanted to sneak away, but he didn't expect to be stopped by the person in front of the princess's courtyard, which made him turn around helplessly, but his face immediately piled up five points of surprise and five points of enthusiasm and said: "Hey, I didn't expect to meet His Royal Highness King Qin here, His Royal Highness is here to visit the princess, right?" ”

The person who called Li Xiu behind was Li Shimin, and I saw that the other party had just come off the horse at this time, followed by a team of cavalry guards, and there was no one else, not even his good friend Changsun Wuji.

"Haha, it's quite a coincidence, is Captain Li here to see the third sister's injury? Let's go in together! Li Shimin didn't see the scene of Li Xiu turning around and leaving, but thought that Li Xiu and him were quite fated, so he invited Li Xiu to go in together, and in the face of this situation, Li Xiu couldn't refuse, so he had to enter the princess's courtyard with Li Shimin.

Li Shimin is the younger brother of Princess Pingyang's mother, so there is no taboo, so he came directly to the inner house to visit Princess Pingyang, but he didn't expect Princess Pingyang to be in the bedroom, the maid told him that the princess was in the greenhouse of the garden, Li Shimin asked the maid to lead the way, but Li Xiu told him that he knew how to go, so the two walked to the garden next to it.

"Captain Li, this king heard that a kind of green vegetable appeared in Chang'an City last winter, which attracted countless powerful people to compete for it, and although this green vegetable came from the third sister's mansion, it seems to have been given to the third sister by Captain Li, right?" On the way to the garden, Li Shimin suddenly spoke.

Last time, Li Shimin was hit by Li Xiu's words that he likes cooking, but then he figured it out, and after he came back, he deliberately asked people to investigate Li Xiu, and the more he investigated, the more surprised he became, bean sprouts, green vegetables, wound stitches, etc. were all created by Li Xiu, and a few days ago Li Xiu also moved Chang'an because of a poem, and countless people were talking about this talented young man, so this time he came to visit Princess Pingyang, in fact, he also wanted to see Li Xiu again by the way, but he didn't expect to meet him outside the door.

"Your Royal Highness misunderstood, I didn't give the princess the method of planting green vegetables in winter, but cooperated with the princess to make money, speaking of which, I didn't expect the green vegetables to be so profitable, in just over a month I earned countless copper coins, with this money, I can build a new yard, and by the way, I will accept a few concubines, this kind of day is simply a fairy!" Li Xiu deliberately said very unambitiously, hoping that Li Shimin would be disgusted with himself after hearing this.

Li Shimin has already been fooled once, so naturally he will not be a second time, so instead of being disappointed, he said with a smile: "Captain Li is really extraordinary, and he can even think of ways to make money that others dare not think, which really makes this king admire!" ”

Hearing Li Shimin's words, Li Xiu couldn't help but secretly scream badly, it seemed that the same method didn't work for him, and he couldn't think of any other way for a while, so he had to stop talking.

However, Li Xiu didn't speak, but Li Shimin didn't plan to stop, but talked with Li Xiu again, chatting all about gossip, Li Xiu didn't dare to really offend Li Shimin, so he had to answer whatever he asked, fortunately, the garden was not far away, and finally came to the door of the greenhouse, Li Xiu was also relieved.

At that moment, Li Xiu pushed the door and went in with Li Shimin, and just saw Princess Pingyang sitting in a wheelchair, watering the flowers and plants, and when he saw Li Shimin, he couldn't help but be surprised: "Second brother, when did you come back?" ”

"I just came back yesterday, and I just came to see the third sister when I didn't settle down at home!" Li Shimin also stepped forward with a smile at this time, and then he looked at the flowers and plants in the greenhouse in surprise, "This greenhouse is really magical, third sister, your flowers and plants can survive, presumably those green vegetables are not alive." ”

"Hehe, I have to thank Captain Li for this, and I heard Uncle Ma say that a batch of vegetables in the greenhouse is about to ripen, and you can bring some to Guanyin and them in a while to see how it tastes." Speaking of the greenhouse, Princess Pingyang deliberately glanced at Li Xiu, and then asked with some curiosity, "Why did Captain Li come here with his second brother?" ”

"Princess Qiyu, I just happened to meet His Royal Highness King Qin at the door, so I came in together." Li Xiu opened his mouth to explain that Princess Pingyang's wounds were healing very well, and there was no need for him to check them every day.

Li Shimin was very interested in the greenhouse, Princess Pingyang took her around, and at the same time asked a few words about the princess's wheelchair, and when she learned that it was also designed by Li Xiu herself, she also appreciated Li Xiu even more. However, the greenhouse is not a place to entertain guests after all, so Princess Pingyang invited them to sit in the living room in front, and the two sisters and brothers chatted a few words, and were worried about snubbing Li Xiu, so they asked him again: "Captain Li, I don't know what important thing you came here today?" ”

"This ......" Li Xiu just wanted to tell the story of the waterwheel, but suddenly thought that the reason why Li Shimin wanted to recruit himself was mainly because he felt that he was a talent, and the greenhouse and wheelchair just now had made him look at himself wrong, if he took out the waterwheel now, I am afraid that he would definitely be even more unwilling to let go of himself, so he hurriedly changed his words, "Princess Qiyu, I actually came to discuss something with Uncle Ma!" ”

"Hahaha~, boy, what did you come to me to discuss?" As soon as Li Xiu's words fell, he saw Ma Ye laughing and walking in from outside, first saluting Princess Pingyang and Li Shimin, and then turning to look at Li Xiu, signaling that he could speak now.

Li Xiu was a little crying and laughing at this time, he had known that Ma Ye had come so coincidentally, he had just said that he had come to visit the princess, but now it was better that he had forced himself into a corner, and he didn't even have room to turn around.

"This ...... Ha ha...... Actually, I'm here to ......" Li Xiu wanted to delay time, hoping that he could come up with an excuse, but not everyone has this thing, and sometimes it doesn't work, it just so happens that Li Xiu is unlucky today, and he didn't come up with any good excuses for a long time.

"What the hell are you doing, boy, if you have something to say, what do you look like?" Ma Ye glared at the moment and said.

"Actually, that's the case, that day I heard the tenants say that it was very difficult to irrigate the fields, so I found someone to design two kinds of waterwheels, but I couldn't find a craftsman to make the waterwheel, so I wanted to find Uncle Ma to borrow some craftsmen, and when the waterwheel was built, both of us could use it."

Li Xiu had already planned to tell the truth, anyway, even if Li Shimin was not allowed to see the drawings today, with Princess Pingyang's temper, she would definitely dedicate it to the imperial court after she knew, and Li Shimin would definitely know it then.

But just as he spoke, he suddenly had an idea to think of a way, since he didn't want this credit, then he simply didn't admit that the waterwheel was designed by himself, anyway, only he and the two maids knew about his own design drawings, as long as he didn't say it, and then told Yuechan that they didn't say it, no one could push this credit on his head.

"Water wheels? This is a good way, I have been in the Tang Dynasty for six years, but I have been worried about internal and external troubles, everywhere is fighting with money, I can't pay attention to agriculture at all, now it's hard to settle down, the imperial court is also preparing to focus on supporting some agricultural facilities, this waterwheel can let the imperial court come forward to promote! ”

As soon as Li Xiu's words came, Li Shimin said a bunch of things that made people not interested, and after saying the above words, he was not finished, only to see Li Shimin suddenly frown and said: "I remember that there were many waterwheels in Guanzhong in the past, but almost all of them were destroyed in the war, and even those craftsmen who could build waterwheels died and escaped. ”

"Actually, I once went to some craftsmen to ask if they would make a waterwheel, but many craftsmen said no, I was a little disappointed, but I didn't expect to meet an old man halfway, dressed like a beggar, he said that he could make a waterwheel, but he was too old to make it, but he could draw drawings for me, just asked me to give him some money, so I took him home, and then he drew two drawings, received the money and left." Li Xiu said nonsense with a mouth full of trains.

There are more martial arts novels in later generations, and countless versions can be made up at will, as for Princess Pingyang, it is none of his business whether they believe it or not.

After listening to Li Xiu's story, Princess Pingyang and Li Shimin couldn't help but look at each other, for this somewhat nonsense story, their first feeling was that they didn't believe it, but there was no evidence that Li Xiu was lying, but this is not the point, the focus is on the drawings of the waterwheel, so Li Shimin immediately said: "Captain Li, I don't know where those drawings are?" ”

Li Xiu hurriedly took out two drawings from his arms and handed them over, Li Shimin took them and opened them, Princess Pingyang also looked sideways, but when she saw the words annotated on the drawings, she was almost angry, because she had seen Li Xiu's words, compared to Li Xiu's writing, Li Xiu's words were crooked and very ugly, and she wouldn't forget them at a glance, so when she saw the words on the drawings, she recognized at a glance that it must have been written by Li Xiu, such an obvious flaw, because he still had a serious story about the old beggar just now?

In contrast, Ma Ye didn't even look at the drawings at all, and even when he heard the story of the old beggar just now, he kept pouting and looking at Li Xiu, with his understanding of Li Xiu, he had already guessed that this kid must not be telling the truth, as for the reason is very simple, it is nothing more than that he does not want to be rewarded by the court for meritorious service.

"What a clever waterwheel, I have seen that kind of pedal waterwheel, it is not surprising, but the waterwheel driven by water power is simply unheard of, and it can take water to a high place without manpower, it is beyond imagination!" When Li Shimin saw the drawings of the hydraulic waterwheel, he slapped the table and exclaimed.

Looking at Li Shimin's stunning appearance, Li Xiu secretly despised it, what is so strange about this most primitive use of water power, not to mention that it is more primitive than the electric motor or internal combustion engine of later generations, even if it is more primitive, it is countless times stronger than it.

Li Shimin praised the hydraulic waterwheel, and immediately wanted to take it away to Li Yuan to see, and then promote it by the imperial court, but Li Xiu was worried that the things on the drawings would definitely not be reliable without practice, so he finally persuaded him to change his mind, and finally decided to let Princess Pingyang make a few tests here, and if it was feasible, it would not be too late to recommend it to the imperial court.

After chatting for a while, Li Shimin said goodbye to Princess Pingyang with great excitement, Princess Pingyang was inconvenient, so Li Xiu and Ma Ye sent Li Shimin out of the house on her behalf, but just when Li Shimin turned over and was about to leave, he suddenly turned his head and said to Li Xiu: "Captain Li, you know how to design greenhouses and wheelchairs, haven't you ever thought about designing a waterwheel yourself?" ”

"Huh? This ......" Li Xiu was also stunned, and then found that he had neglected such a big loophole, but he had already made up his mind not to admit it, anyway, who wants this credit, so I saw that he replied with a face as usual, "Your Highness doesn't know, as the so-called art industry has a specialty, although I understand the principle of greenhouses and wheelchairs, but I can't steal the waterwheel, so I can't do anything, fortunately, I have the Tang Dynasty Hidden Dragon Crouching Tiger, so I met that strange person in the next place!" ”

Seeing that Li Xiu didn't admit it at such a time, Li Shimin couldn't help but feel angry and laughing, but he really couldn't do anything about him, so he had to shake his head helplessly and said: "Captain Li is high-spirited, this king will take the time to visit again in the next few days!" ”
