The fire on the coal stove is burning, and the remaining water in the pot is also boiled dry, only to see Yan Yuru standing by the stove rolling up his sleeves, revealing two jade arms like white lotus, the spoon in his right hand scoops out a little oil from a clay pot next to him and pours it into the pot, and when the oil is hot, a faint green smoke comes out, and the shredded ginger and shallots are put into the pot, and finally the leftover steamed wild vegetables from yesterday are poured into the pot and kept burning, and soon a tempting fragrance wafts out of the kitchen.

It's noon now, and Yin Niang hasn't come back since she went out in the morning, but Yan Yuru isn't too worried about this, after all, there is Zhao Yan's other courtyard here, and ordinary thieves and robbers don't dare to come at all, and there are no too fierce beasts in the nearby mountains, plus Yin Niang has also learned some punches and kicks with herself, and one or two strong men are not her opponents, as for the reason why she hasn't come back yet, it is estimated that she is likely to dig wild vegetables again.

Sure enough, just as Yan Yuru fried the steamed wild vegetables, she heard the door being opened, and then Yinniang's familiar footsteps sounded, and soon shouted: "Sister, what are you making delicious, why is it so fragrant?" ”

"It's not delicious, just stir-fry the wild vegetables you steamed yesterday, I didn't expect it to taste so fragrant." Yan Yuru in the kitchen also said with a smile, she didn't know how to cook, but since she moved here, three meals a day have to be solved by themselves, although most of them are usually made by Yin Niang, but Yan Yuru often comes to help, and now she can cook by herself, and she is also the first time she made this fried wild vegetable today, but she didn't expect it to taste good.

I saw Yinniang running into the kitchen with a basket at this time, first took a long breath, and then praised with a happy face: "Sister, your cooking skills are really amazing, it seems that I have a good mouth today!" ”

"Little glutton, hurry up and wash your hands, you can eat it right away." Yan Yuru couldn't help but feel a little funny when she saw Yinniang's appearance. Speaking of which, although their lives are hard, she has laughed more during this time than in more than ten years before.

After Yinniang left school, she did go to dig wild vegetables, and she was busy almost all morning, and now she was already hungry, and when she heard Yan Yuru's words, she immediately put down the basket full of wild vegetables. She turned around and was about to wash her hands, but then she suddenly thought of something, and then turned around and took out two palm-length fish from the basket and said, "Sister, look, this is the fish caught in the fish cage I put down yesterday, and we have fish soup to drink tonight." ”

Seeing the two fish in Yinniang's hand, Yan Yuru also said with some surprise: "I didn't expect Yinniang to know a lot of things, and you really caught a fish." ”

"Giggles, of course, I learned this method from my father before." Yin Niang heard Yan Yuru's praise. couldn't help but say proudly, but when her father was mentioned, her voice couldn't help but be low, it was her father who had to sell her in order to support his two younger brothers, fortunately she finally met Yan Yuru, otherwise she wouldn't know what she would have become?

When Yan Yuru saw Yinniang's appearance, she immediately guessed what she was thinking. At that moment, he hurriedly handed her the fried wild vegetables that had been filled and said, "Yinniang, how about you hurry up and taste the taste, isn't it really delicious?" ”

Yan Yuru's method really worked. Yinniang's attention was immediately attracted by the food, and she put the sadness behind at the moment, took the bowl and grabbed the chopsticks and pulled them into her mouth, but she was hot at first and inhaled the cool air, but even so, she was still reluctant to spit out the contents of her mouth. Finally, after swallowing it with great difficulty, I saw that Yinniang immediately praised: "Sister, what you made is so delicious, don't drink fish soup tonight, just eat this!" ”

When Yin Niang said this, she took a few mouthfuls into her mouth again. Then he raised his head and continued: "It's just that stir-frying wild vegetables is a little too oil-intensive, and now that oil is so expensive, we don't seem to have much oil." ”

At the end, Yin Niang shook her head with a look of chagrin, as if she was regretting that she would not be able to eat such a delicacy often in the future. Yan Yuru also tasted her own fried wild vegetables at this time, and now the taste is really good, but it is not as exaggerated as Yin Niang's table, it is estimated that she is too hungry, after all, she has done a morning's work today, and she only drank some rice soup in the morning, and kept all the rice in the soup to herself. As soon as she thought of these, Yan Yuru felt warm in her heart, although Yinniang was the maid she bought, but in fact, in her heart, Yinniang was her dearest person, and only from her could Yan Yuru feel a long-lost family affection.

After lunch, Yan Yuru helped Yinniang wash the dishes again, and she didn't have the same appearance as before. But just when they were washing their hands, Yin Niang took out a piece of paper from her arms and handed it to Yan Yuru and said, "Sister, help me take a look, I can't understand a lot of things written on it." ”

Yan Yuru wiped her hands with a towel, took the paper in Yinniang's hand and looked at it, but the things on it surprised her, because the total score on it was the unintelligible words she saw at the gate this morning, and when she saw the explanation behind these symbols, she showed a surprised expression, she didn't expect that these symbols were actually replacing the numbers and various operations in arithmetic, so that the arithmetic process can definitely be greatly simplified.

"Yinniang, where did you get this thing, are those on our gate really written by the children in the Zhuangzi?" Yan Yuru asked in surprise at this time, she has been well-read since she was a child, and she also has considerable attainments in arithmetic, so she naturally saw at a glance the benefits and convenience of using various symbols to replace numbers and the process of operation. But it was precisely because of this that she began to wonder how the symbols on the door of her house this morning, such an important thing, could have been written by some children?

"Giggles, I'm afraid my sister won't believe it, this piece of paper was given to me by His Royal Highness the King of the County himself, and as for the person who scribbles on our door, he is indeed a child in Zhuangzi." Yin Niang was smiling very happily at this time, especially thinking of Zhao Yantang, a county king, but he put down his body to teach the children of the farmers to read, which was really a very interesting thing.

"What the hell is going on, why is it related to the king of the county again?" Yan Yuru heard that this matter was related to Zhao Yan, and couldn't help frowning and asked, although she and Zhao Yan were neighbors, for some reason, she didn't want to have any contact with Zhao Yan the most.

Yin Niang didn't notice the abnormality on Yan Yuru's face, and smiled at the moment how she got to Zhuangzi today to inquire about the situation of the school, and then went to the school to complain, but she didn't expect that the teacher of the current school turned out to be Zhao Yan in the end, especially at the end, she also mentioned that Zhao Yan also invited herself to listen to the class, and Yin Niang was also very excited when she said this.

Yan Yuru had been listening to Yinniang tell the story very quietly, and finally pondered for a while before suddenly whispering to herself: "This Zhao Yan's appearance is indeed very strange, and what is even more unbelievable is that he seems to have too many mysteries, no wonder that person is so interested in him?" ”

"Sister, although His Royal Highness the King of the County behaves a little strangely, he always smiles when he talks to me, without the slightest pretension, and he can teach the children of the farmers to read for free, so I think he must be a rare good person!" In the end, Yin Niang concluded again, and labeled Zhao Yan as a good person.

"Well, although Zhao Yan used to mess around a little, since he got married, he has indeed done a lot of good things for the benefit of the country and the people." Yan Yuru also nodded when she heard this, she knew more about Zhao Yan than ordinary people, and knew many things that had not been circulated in the outside world, such as the method of post-disaster epidemic prevention and control to save countless people, as well as the civil strife in Liao, etc., few people knew that these things were from Zhao Yan's hands, but Yan Yuru knew very clearly, but it was knowing these that made her have more scruples about Zhao Yan in her heart, because she always felt that Zhao Yan was not as simple as it seemed.

"Sister, can you help me tell me what the symbols on this paper mean, why I can't understand some of them at all?" At this moment, Yin Niang hugged Yan Yuru's arm again and shook it and asked, although she was literate, she had not had much contact with arithmetic, at most she could calculate some simple accounts, so she naturally couldn't understand the meaning of those operation symbols on the paper.

"Well, these are actually related to arithmetic, I'll try to explain it to you!" Yan Yuru smiled and said, she and Yinniang depended on each other, and she was also very fond of her, seeing that Yinniang was interested in these symbols in her hand, she patiently talked about it for her at the moment, but Yinniang was really not a material for learning mathematics, and she felt sleepy after listening to it for a while, and finally fell asleep by Yan Yuru.

In the afternoon, Yan Yuru pondered for a long time about the problem of livelihood, but in the end, her head hurt when she thought about it, and she didn't think of any good way, so she simply put this matter aside, and then took out the paper full of symbolic meanings that Zhao Yan gave to Yinniang to study, first, to take a break, and secondly, she felt that Zhao Yan's method of using symbols to evolve arithmetic not only simplified the process of calculus, but also seemed to have its own system, so she wanted to study some laws from these symbols.

However, mathematics is a very rigorous science, it is the crystallization of wisdom formed through the accumulation and efforts of countless generations, although Yan Yuru is a woman with seven exquisite skills, but it is impossible to study any results in a short period of time, she can't even use these symbols to calculate, which makes Yan Yuru also more curious about this kind of arithmetic.

As time passed, the sun slowly went down, and Yan Yuru didn't gain much from studying for an afternoon, but at this moment, she suddenly turned around very vigilantly, but there was a figure hidden in the darkness in the room at some point. (To be continued!)
