The old man who collected the money did not leave, but quickly chased in the direction of Wuhou's departure, without asking, he knew that he was going to go to the county government to testify to Zhang Daren, his simple thoughts did not consider what kind of treatment he would receive in the court, but was very persistent in thinking that since others had come out for themselves, then they should repay others, which was the most simple side of the people of the Tang Dynasty.

Looking at the old man's hurried appearance, Jia Yi had no intention of catching up, from the calm appearance when Zhang Daren and Wuhou left just now, Jia Yi drew out the guess in his heart that Zhang Daren was likely to be a ranger, the ranger would not go to court so easily, in this era of believing in chivalry and forbiddenness, they deeply knew that once they entered the yamen, they would not have good fruits to eat.

Since Zhang Daren is not a ranger, then he must be an official, in this case, Jia Yi has no need to worry about him, it is more practical to go back early.

On the way back, Jia Yi saw a lot of stalls selling seeds, I don't know if this rapeseed is too much or how to drop, but all the people who sell seeds along the way, basically have rapeseed for sale, Jia Yi did not hesitate to buy all of them, the edible oil is only too little, definitely not too much.

When Jia Yi returned to the Lin Mansion, he was followed by a cart, and there were a lot of sacks piled up on the cart, except for the seeds that Jia Yi bought from the old man, all the others were rapeseed, and the oil squeezed out of this cart of rapeseed was definitely enough for a year.

Jia Yi called Jia Er, and helped put all the sacks in the car in the first yard, and he casually opened the other seeds that the old man bought for himself, which looked inside, obediently, there were peanuts, and other seeds Jia couldn't see it, and he needed to plant it to know, but the peanut's unique size, he could only see it at a glance, although the size of the peanut was not very big, but this is not a thing, as long as it was cultivated, it could always grow a big peanut.

Peanuts were also called longevity fruit in the Tang Dynasty, but this plant has never been able to enter the sight of the masses, because wild peanuts taste a little bitter, which may be the reason why people are not familiar with it.

But in Jia Yi's eyes, this peanut is a godsend, the oil yield of peanuts is much higher than that of rapeseed, and peanuts can also be eaten as a vegetable, and the full peanuts will become a good food regardless of whether they are boiled or fried.

Just when Jia Yi was excited to prepare to save these peanut seeds, the elusive Sun Simiao suddenly appeared beside Jia Yi, and his eyes fell into the sack in Jia's hand for the first time.

"The longevity fruit can calm the stomach and nourish the qi and blood, a good thing." As he spoke, he casually threw a few more into his mouth, and chewed slowly under Jia's red-necked gaze.

"What do you think of me like this, I just ate a few of your longevity fruits, although there are not many of these things, but you can always find some all over the mountains, you shouldn't be so stingy." Sun Simiao ate two peanuts, and then noticed that Jia Yiyi's gaze towards him was full of unkindness.

"This is my fucking seed." Jia Yi gritted his teeth and grabbed the sack in his hand to death, so he was obviously afraid that Sun Simiao would grab it.

"Stingy." Since Jia Yi said that this is a seed, Sun Simiao no longer pays attention to these peanuts, although I don't know what Jia Yi thinks, he actually thought of planting this kind of medicinal herb with a bitter taste, could it be that he wants to study medicine?

Jia Yi went back to the room angrily, put the sack he was holding in his hand, put it under the bed, and after two days there was nothing to do, he planted it in the yard to try, it happened to be the end of spring, and it was a good time to plant peanuts.

When they came to the courtyard again, the four members of the Lin family plus Jia Erzheng were all standing in front of the small pile of rapeseeds, discussing fiercely why Jia Yi bought so many rapeseeds.

"It should be for stir-frying, although I don't know what these rapeseeds can be fried, but I still believe that Jia Yi must be used for stir-frying." Lin Baoyu said something rarely, and was very foodie that Jia Yi would use these rapeseeds to stir-fry.

"It shouldn't be, it's used for stir-frying, these are too many, and our family can't eat them for a year and a half." Lin Ruyu showed her wisdom in a timely manner, of course, Jia Yi thought that this was a heart-to-heart connection between the prospective couple.

"As soon as Jia came, wouldn't you know if you asked him?" Lin Meiyu was the first to find out about Jia Yi's arrival, but when the words fell, Lin Ruyu was like a cat whose tail had been stepped on, and almost jumped up, if it weren't for Jia Yi's arrow step up and grabbed her hand, maybe she would have run away by this time, even so, a little face had already turned red, and even her neck was half red.

"Ahem, Jia Yi, men and women don't kiss, you two haven't married yet." Old Man Lin glanced at Sun Simiao, who was quietly born beside him, and felt that when outsiders were present, it was better for the two of them to keep the necessary distance.

When Jia Yi heard this, he reluctantly let go of his hand, and Lin Ruyu was not running, so he stood by Jia Yi's side.

"Jia Yi, what are you going to do with so many rapeseeds?" Sun Simiao stroked his beard and looked at Jia Yi.

"Ahem, this, secret." How could it be possible to share such a confidential thing as oil extraction with Sun Simiao.

"Brassica seeds, stagnation of blood, breaking cold air, reducing swelling and dissipating knots. Treatment of labor difficulties, postpartum heart and abdominal diseases, red dan fever and swelling, gold sores and blood hemorrhoids, do you really want to study medicine? didn't get an answer, Sun Simiao figured out an answer that he thought was reasonable, but the speaker was unintentional, the listener was intentional, and the other people standing around all looked at Jia Yi with wide eyes, Sun Simiao didn't understand anything else, this "postpartum heart disease" was heard clearly, and they all thought about whether Jia Yi should treat the disease of a woman giving birth.

"Well, I think if I don't say it, you'll think I'm going to be a midwife, but I can't say it too clearly, you just need to know that it's for food." After Jia Yi finished speaking, he ignored everyone and pulled Jia Er into the second courtyard.

"Little Er, next the eldest brother is going to give you a very important task, do you think the eldest brother can fully believe you?" Jia Yi looked at Jia Er with a serious face, and his eyes were staring straight at Jia Er's eyes, as if he could see through Jia Er's thoughts in this way.

Jia Er was furious by Jia Yiyi, nodded tremblingly, and did not speak.

"Okay, now I'll tell you, those rapeseeds outside are used to make oil, the kind of oil used to make braised pork, and I'll tell you how to make it in the next few days, but I hope you can keep it a secret, because this is the root of our brothers' fortunes."

"Well, don't worry, big brother, I swear I'll keep this a secret."

"Okay, let's go out, I'll tell you how to make oil in two days."

Jia Yi hasn't figured out how to get a large-scale oil-making device, if it's too big, Jia Er's small body can't be operated, if it's too small, it's too inefficient, and he really can't think about how to get it for a while, and he is upset about it.

In fact, there is another way to make rapeseed oil, that is, beating, but this movement is too big, if it is operated in the Lin Mansion, this family will have to be tortured into a nervous disease, and now they can only use donkeys instead of manual labor.

Just when Jia Yi was thinking about how much equipment to make, Zhang Daren, who followed Wuhou to the county office, had already returned to the Lin Mansion.

"It's a bit slow to come back." Jia Yi's headless words made Zhang Daren's face full of doubts, what do you mean?

In Jia Yi's cognition, as long as a slightly reasonable official, facing a businessman, then the last person to be hit by the board must be a businessman, this year people are divided into levels, Shinong industry and commerce is the classification of the social status of all people, scholars are scholars and officials, at the top of the society, business naturally refers to businessmen, social status is very low, between this high and low, how can there be the benefits of businessmen.

"Don't pretend, let's talk about it, why do you want to rely on me, sir." Jia Yi thought that he had not done anything illegal and undisciplined, so there was a person with official status who thought of a small idea to enter the Lin Mansion and come to Jia Yi's side, if he wanted to say that he had no other ideas, and killed Zhang Daren, Jia Yi didn't believe it.

"How do you see that?" Zhang Daren looked at Jia Yi with a smile on his face with a stunned face, and he didn't know where Jia Yi saw his identity.

"You didn't have any nervousness when you faced Wuhou just now, which basically does not appear in the body of the farmer and the ranger, and then you obviously beat Wang Mengfa, but now you are standing here intact, these two points are enough to explain your identity." Jia turned into a detective in an instant, and only by virtue of two points, he determined the identity of Zhang Daren's official body.

"To correct me, I didn't hit Wang Mengfa, I just pushed him, I didn't fight." Zhang Daren tried to divert Jia Yi's attention, but when he finished speaking, Jia Yi still looked at him with a smile, which made him know that it was impossible to get through the trick.

"Okay, I admit that I am an official, and as for my affiliation, it is really inconvenient to tell you, but I can tell you that I have no malice in approaching you."

Every official who is running around outside has a secret that cannot be said, and Jia Yi also knows this, so he didn't delve into it, but why did Zhang Daren approach him, this matter can be asked clearly.
