"Why is it like a fire on this day, can't you have some cool breeze?" Early in the morning, Li Xiu was directly woken up by the heat, and when he got up, there were more wet marks in the shape of a human figure on the bed, and his whole body was greasy and greasy, and he felt very uncomfortable. Pen, fun, and www.biquge.info

At that moment, Li Xiu came out of the bedroom, but found that the sun in the east had just revealed half of his face, but the air was already stuffy, and he felt like he was on fire when he took a breath, but even so, Li Xiu still played a set of Tai Chi as usual, and the clothes on his body were quickly soaked, and then he rushed into the bathroom and took a warm shower, the water in the yard was already so hot before the sun was seen, and it was estimated that he would have to add cold water to take a bath at night.

After taking a shower, he changed into clean clothes, which made him feel much more comfortable, but as soon as he got out of the bathroom, Qi Niang rushed in sweating, and then Liu Er and Yuechan also rushed in, which also made Li Xiu feel a little emotional, and the family should have repaired a few more bathrooms at the beginning.

"Master, breakfast is ready, do you and Qi Niang eat it now?" Yuechan walked out with her hair wet after taking a shower and said, it's hot outside, and the kitchen is even hotter, and it's really hard for her to make breakfast in the kitchen like a steamer, which is why she rushed to the bathroom just now, and it is estimated that her whole body is soaked.

"This ...... Qi Niang, do you want to eat it? "People have no appetite when they are hot, Li Xiu really feels that he can't eat it now, but he can't waste the fruits of Yuechan's labor, so he asked Qi Niang.

"It's so hot, I just want to eat ice food!" Qi Niang was lying on Li Xiu's recliner at this time and shouted, the so-called ice food is the ancient cold drink, which is generally only available to aristocratic families, and it is much simpler than the cold drink of later generations, most of them are ice chips poured with honey and milk.

"Want ice?" Li Xiu also had an idea when he heard this, and immediately patted his thigh and said, "I have a way, Yuechan, you go and clean up your things, let's go to the princess for the summer, she has an ice cellar there, you can eat as much ice as you want!" ”

As soon as she heard that there was ice to eat, Qi Niang also jumped up happily, Yuechan and Liu Er were also hot and couldn't stand it, so they packed up a few things and went out of the inner house with Li Xiu, but at this time, Qi Niang suddenly thought of one thing, and stopped at the moment and said: "Brother, the day before yesterday, Brother Chengdao said that he was coming today, what should he do if we leave?" ”

"On such a hot day, he shouldn't come, and the fat sister is all at home, if he really comes, just let the fat sister tell him to go to the princess!" When Li Xiu heard this, he immediately replied, he was more inclined that Li Chengdao should not come today, after all, this ghost weather is too hot.

However, what Li Xiu never expected was that as soon as they arrived at the door, they found that Li Chengdao was galloping on a horse in the distance, and there were many people behind him, most of them were his guards, and Li Xiu didn't care at first.

"Sir, where are you going?" Li Chengdao rode his horse to Li Xiu, and immediately threw off the saddle and dismounted and asked, only to see that he was also sweating profusely at this time, and the clothes on his body were all attached to his body, and it was estimated that it was hot enough.

"Why are you here on such a hot day, we are all going to your aunt's place to escape the heat." Li Xiu was also quite surprised when he saw Li Chengdao, this kind of ghost weather Li Chengdao is also coming, and this spirit even Li Xiu is a little moved.

"Hehe, Mr. doesn't have to bother to go to my aunt's anymore, I know that Mr. doesn't have an ice cellar here, and it's too hot today, so I specially brought some ice from the palace, enough for Mr. to use!" Li Chengdao stretched out his hand and pointed behind his back when he said this, and Li Xiu realized that among the original Li Chengdao's guards, there was a big car, which was covered with a thick quilt, but the water was still dripping under the car, and it was estimated that it was filled with ice.

"Great, I finally have ice food to eat, thank you so much Brother Chengdao!" Before Li Xiu could speak, Qi Niang next to her jumped up happily and said, thinking that she could eat cold and delicious ice food earlier, she was happier than anyone else.

Seeing Qi Niang's happy appearance, Li Xiu also smiled helplessly, and said to Li Cheng at the moment: "You have a heart, let people pull the ice in, speaking of which, this kind of ghost weather without ice is really difficult!" ”

Hearing Li Xiu's praise, Li Chengdao was also very happy, and immediately asked people to pull the ice in, speaking of which, he used to come with Princess Pingyang, but after getting familiar with this time, he usually came directly to Li Xiu, and by the way, he sent someone to inform his aunt.

At that moment, Li Xiu took Qi Niang and the others back to the inner house, but at this time, he saw Li Chengdao walking in with a young man about twenty years old, looking at the other party's appearance, it didn't seem like a guard, and even Li Chengdao seemed to have a little respect for him, which also made Li Xiu very curious, there were too many people just now, and he really noticed that there was such a person around Li Chengdao.

"Sir, let me introduce, this is my second uncle's palace chronicle to join the army, Li Chunfeng Li joined the army, is the arithmetic master of our dynasty, and is usually responsible for teaching me some arithmetic basics, this time I came to visit Mr!" Li Chengdao introduced Li Xiu with some apprehension at this time, because he brought people without telling Li Xiu in advance, so he was worried that Li Xiu would be blamed for this.

"Huh? Li Chunfeng? Li Xiu couldn't help but show a surprised expression when he heard this name, and then looked the young man next to Li Chengdao up and down, only to see that the other party was seven feet long and had good facial features, standing there looking chic, even a little more handsome than him, well, just a little bit of a loss.

There are too many dazzling names in the early Tang Dynasty for people to remember, but the reason why two of them are remembered is not because they made any contributions on the battlefield, nor what high-ranking officials they did, but because the two of them were the most famous gods in the Tang Dynasty.

In fact, it is indeed a bit wrong to say that Li Chunfeng is a god, because he was the best mathematician and astronomer in the early Tang Dynasty, and he was also proficient in calendar, yin and yang, easy to learn, etc., so he could be said to be an extremely rare genius, so Li Xiu was so surprised when he saw him.

"I took the liberty to visit, and I hope that Li Xianjiu will not blame him for being abrupt!" I saw Li Chunfeng step forward at this time and saluted Li Xiu.

"Li doesn't have to be polite to join the army, please take a seat!" Li Xiu also said very politely at the moment, although Li Chunfeng was only a small member of the army, but he did not dare to slack off in the slightest, if it came to real knowledge, he was afraid that he would not be as good as the other party.

Li Chunfeng was still a little worried that Li Xiu would blame, and he couldn't help but be very surprised when he saw that he was so enthusiastic about himself, but although he was young, he was very calm, and he quickly smiled and thanked him, and then sat down with Li Chengdao, at this time, Yuechan and Liu Er and others put the ice cubes in the wooden basin and carried them in, and closed the window, except for the melting of the ice cubes, the whole room felt cooler, and then they made ice food and sent it up, eating these heart-cold broken ice, Li Xiu finally felt much more comfortable.

"Li joins the army, I don't know why you came here today?" Li Xiu smiled and said a few polite words to Li Chunfeng, and then asked, in fact, he wanted to ask Li Chunfeng more, he was obviously Li Shimin's person, why would he teach Li Chengdao arithmetic, but unfortunately this question is too sensitive, and Li Chengdao is here, it is really inconvenient to ask.

"Actually, it's like this, when the first few **** taught the county king to learn arithmetic, I accidentally saw the notes he brought back from Li Xijiu, as well as his novel algorithm, I was surprised at the time, and then after learning from the county king, I found that Li Xijiu's arithmetic method is very simple and straightforward, if it is greatly promoted, it will definitely replace the current arithmetic method, I don't know if Li Xianjiu has this heart?" Li Chunfeng also looked a little excited at the end, creating a new way of arithmetic, which he didn't even dare to dream of before, but the Li Xiu, who was two years younger than himself, did it.

"Promotion? I'm afraid I don't have time for this? Li Xiu was very embarrassed, just teaching Qi Niang and Li Chengdao had already made him feel very busy, and he usually even had a lot less time to rest, where would he have time to pay attention to these?

"It doesn't matter, if Li Xianjiu doesn't have time, he can promote it on his behalf, just before he went down, he sorted out the notes brought back by the county king, wrote a book of "Li Gongzi Arithmetic", and asked Li Xianjiu to take a look!" Li Chunfeng obviously came prepared, and when he heard this, he immediately took out a stack of manuscript paper from his arms and sent it to Li Xiu, with a sincere smile on his face, which made it impossible to refuse.

In desperation, Li Xiu had no choice but to pick up the manuscript paper and read it, which began with a preface, introducing Li Gongzi to Li Xiu, and then introducing Li Xiu's life and fame, which was full of praise, making Li Xiu a little embarrassed to see it.

When he saw the content inside, he was even more surprised by Li Xiu, although Li Chunfeng said that he used Li Chengdao's notes to sort it out, but the content in it was basically written by himself, with his arithmetic talent, he could naturally understand Li Xiu's new arithmetic better than anyone else, and the content of the book was also from shallow to deep, and the content involved was also very comprehensive, some Li Xiu had not talked about it at all, but he could draw inferences from one another, and it is no exaggeration to say that this book can be used as a textbook for primary school mathematics in later generations.

"Li is really a great talent, this book is so well written, if it is circulated, it will definitely allow more people to accept the new style of arithmetic, and I am also convinced!" Li Xiu also praised Li Chunfeng at this time, worthy of being the most famous genius mathematician in the early Tang Dynasty, who compiled a primary school textbook in such a period of time.

"So Li Xianjiu agreed?" Li Chunfeng's eyes also lit up at this time.

"That's natural, it's just that Li really doesn't have time, so everything is entrusted to Li to join the army!" Li Xiu immediately nodded and said, anyway, he doesn't need to work, and he can also promote mathematics, which will have a positive effect on Datang's science and technology, and he will naturally not object.

Seeing Li Xiu nodding, Li Chunfeng was also very excited, and immediately got up to say goodbye, planning to go back and immediately prepare to promote this new style of arithmetic, Li Xiu was not good at keeping him anymore, and personally sent him out of the door, but just when Li Chunfeng was about to leave, he suddenly thought of another thing, and immediately turned to Li Xiu and smiled: "Li Xianjiu, His Royal Highness the King of Qin is coming back, thanks to your reminder of Tuyuhun before, this time His Royal Highness returned triumphantly, and he will definitely thank you for coming to the door at that time!"
