Cao Lu asked people to push a car, and then signed a document with Zhao Yan to divide the paperwork, and then left happily with the method of making honeycomb coal and the pattern of a one-man machine for making honeycomb coal. The honeycomb coal of later generations has been all produced by machines, but when Zhao Yan was a child, he was beaten manually, using a manual machine, the structure is very simple, only one can be played at a time, and skilled people can beat dozens of them in a minute, and the efficiency is not low.

I saw Cao Ying walk in front of the car at this time, lifted the cloth on the car and looked at it, and glanced at Zhao Yan next to him and said: "Let out such a large amount of money, just exchange it for such a pile of wood, the county king is really generous." ”

"Hey, is it okay to have a little conscience, I'm doing this for the sake of your Cao family, okay?" Zhao Yan said very dissatisfied, he didn't let Cao Ying bargain with Cao Lu just now, firstly, because he didn't want to hurt the harmony of their father and daughter because of this small profit, and secondly, he fell in love with Cao Lu's bed crossbow, so he added an additional condition to the back, and Cao Lu agreed without saying a word.

"What do you call our Cao family, now I am no longer a member of the Cao family!" Although Cao Ying was grateful to Zhao Yan for his kindness, she still argued stubbornly.

"Haha, I forgot about this, you are now a member of our Zhao family, naturally you have to think about the benefits of our Zhao family, this is wrong for your husband, I apologize to you!" Zhao Yan said with a smile, although the relationship between him and Cao Ying has improved, Cao Ying still avoided the fact that the two were husband and wife, and this time she took the initiative to mention it.

Sure enough, when Cao Ying heard Zhao Yan's words, her face immediately turned red, and she wanted to argue a few more words, but unfortunately she opened her mouth several times but couldn't say anything, and finally she could only stomp her feet coquettishly, turned around and ran back to the room. Looking at Cao Ying's rare shy demeanor, Zhao Yan laughed, it was a very interesting thing to have a little daughter-in-law like Cao Ying from time to time.

Next, Zhao Yan asked the people of the palace to send this bed crossbow to the courtyard outside the city, although this bed crossbow is just a kind of goods, but except for the crossbow arm can not be used, other places are genuine, and even according to Cao Lu, this extra bed crossbow was originally eliminated in the army, but because the crossbow arm is not well matched, so he got it to his home as a collection.

Zhao Yan doesn't have a hobby of weapon collection, the reason why he wants to come to this bed crossbow that can't be used is all because when he heard Cao Lu say that the crossbow arm of the bed crossbow is expensive, he had an idea in his heart, if it can be realized, it can greatly reduce the cost of the bed crossbow, but he is not too sure of this idea, he needs to test it himself, Cao Lu's bed crossbow just allows him to make a real yàn.

At noon, Cao Lu took Cao Ping to come again, speaking of Cao Ping as the head of the family, this kind of thing should have been done by him, but yesterday he drank too much, and he was angry with his son Cao Song, so he didn't fall asleep all night, and didn't get up until noon today, when Zhao Yan saw him, Cao Ping's face was still a little tired, but more of it was still happy, because Zhao Yan finally solved his biggest concern, so he came to thank him.

Zhao Yan naturally didn't dare to accept Cao Ping's thanks, but just said that these were what he should do, not to mention that he also benefited from it. However, Zhao Yan did not forget to intercede with Cao Song, especially pointed out that if it weren't for Cao Song, he would not have known the predicament faced by the Cao family before, so Cao Song could be regarded as a credit offset this time.

Cao Ping heard Zhao Yan's words of intercession for his son, and now he also felt that although his son was not successful, but his luck was not bad, and he actually helped the family through a big difficulty by mistake.

Thinking of this, Cao Ping finally nodded and said: "Okay, since it was the county king who interceded for that muddy boy, I won't punish him anymore, but my son is really worrying, since the county king treats him as a friend and his brother-in-law, so in the future, I will ask the county king to supervise him on behalf of the old man, so as not to cause trouble at home outside again!" ”

Cao Ping is really cunning, knowing that he can't control Cao Song's son, he turned out to be Zhao Yan, although Zhao Yan's reputation outside is even worse than Cao Song, but after these two contacts, Cao Ping now Zhao Yan may not be as unbearable as the legend, for example, although this honeycomb coal seems simple, it is really difficult for ordinary people to come up with.

"Uncle rest assured, in fact, Brother Jiu'er doesn't have any big problems, the main thing is to stay at home and do nothing too idle, so I think you might as well find something for him to do, as long as he gets busy, he won't have time to mess around." Zhao Yancai didn't have time to help Cao Ping manage Cao Song, so he asked Cao Ping to find something to do for Cao Song, maybe after getting busy, Cao Song would be able to overcome his psychological barrier and not steal anything in the future.

Cao Ping heard Zhao Yan's words and thought about it seriously, and also felt that there was some truth, but Cao Song's stealing had already spread all over the capital, even if he made up for the lack of sanitation officials, I am afraid that he would be ridiculed, let alone promoted in the future, so it is definitely not possible to take a career in office, but there are also many children of the Cao family who manage the family business, maybe Cao Song can give it a try.

"By the way, I don't know how you plan to use honeycomb coal, father-in-law?" Zhao Yan suddenly asked with concern, although honeycomb coal is a huge way of wealth, it is also very easy to be counterfeited by others, if one does not let the Gao family learn it, then they may only marry others.

For Zhao Yan's worries, Cao Lu also guessed immediately, and said with a smile at the moment: "Don't worry, there are only a few big coal mines around Kaifeng City, and the crushed coal produced in the past can't be sold at all, so it can only be piled up around the coal mine to occupy space, and now our Cao family only needs to send someone to negotiate with them, and they can definitely contract their annual crushed coal output at a low price, and as long as they sign the paperwork, they can't sell it to others, so even if the method of making honeycomb coal is learned in the future, we don't have to worry, Because only our Cao family's coal shop has low-priced crushed coal to sell! ”

"High!" Zhao Yan couldn't help but stretch out his thumb when he heard this, the Cao family is worthy of being a family that has been in the coal business for many years, and they did not intend to monopolize the manufacture of honeycomb coal from the beginning, but started from the source and contracted the output of crushed coal from the surrounding coal mines.

Just when Zhao Yan was chatting with Cao Ping and Cao Lu's brothers, suddenly Xiaodou Sprouts came in and reported: "King Qiyu, the fifth brother of the eldest lord's family in the East Courtyard asked to see him, saying that you asked him to bring a message to see him and have something to discuss!" ”

"Isn't the fifth brother of my cousin's family doing things in gunpowder, what are you looking for him?" Before Zhao Yan could speak, Cao Ping spoke first, their Cao family is divided into more than 20 branches, and they live in different compounds, and the east courtyard is the courtyard where his cousin Cao Yu lives, and Cao Yu is big at home, so he is called the master of the East Courtyard by the people of Cao Mansion.

"Oh, the fifth brother was called by me, and when the virtuous son-in-law visited my Qianjun Pavilion today, he seemed to be very interested in gunpowder, and I heard that the fifth brother was working in gunpowder, so I wanted to meet him." At this time, Cao Lu replied, hearing this, Zhao Yancai finally remembered that he really wanted to know the gunpowder level of the Great Song Dynasty, and if the other party was reliable, he also wanted to help the Great Song Dynasty improve it.

After Cao Lu finished talking to Cao Ping, he turned his head to Zhao Yan and said: "Virtuous son-in-law, the fifth brother of my cousin's family is named Cao Chong, and he is older than Ying'er, you can just call him the fifth brother, and we will not mix up the affairs between you young people, and my eldest brother and I will leave!" ”

Zhao Yan actually wanted Cao Lu and Cao Ping to listen to their gunpowder theory, but thinking that they didn't pay much attention to gunpowder, and the other party was full of thoughts about the family business, it was estimated that he was not interested in hearing this, so he didn't keep it at the moment, and personally sent them out of the room, and at this time Zhao Yan appeared, a black and thin young man in his twenties was standing in the courtyard, and when he saw him send Cao Lu and Cao Ping out, he first saluted the two elders, and then smiled at Zhao Yan reservedly.

"Fifth brother, this is your brother-in-law, Zhao Yan, the king of Guangyang County, he said that he was looking for you for something, you can go in and talk!" Cao Ping helped Cao Chong introduce Zhao Yan before leaving, and then left here.

Cao Chong bowed down and sent the two elders away, and then saluted Zhao Yan again: "Cao Chong has seen the king of the county!" ”

"Haha~, what is the fifth brother polite, this is at home and not outside, how can there be any county king who is not a county king, you can call my name directly, or just call me the third brother directly like the ninth brother!" Zhao Yan smiled and took Cao Chong's hand and entered the living room, although this Cao Chong is not very old and looks very ordinary, but he is very stable, which makes people feel that he is a trustworthy person at first sight, this may be the demeanor that the real children of everyone should have.

Cao Chong's enthusiasm for Zhao Yan was also a little surprised, but he had a steady personality, but he did not lose his temper, as Zhao Yan entered the living room and sat down, then he spoke again: "Since the king of the county said so, then I will call you the third brother, I heard that the second cousin sent someone to say that the third brother has something important to look for me today, but unfortunately I am going to gunpowder to be on duty today, so I am not at home, as soon as I came back, I immediately came here to see the third brother." ”

"Haha, in fact, there is nothing, but today I visited my father-in-law's Qianjun Pavilion, there are all weapons in it, but there are no gunpowder weapons, it just so happens that I am also a little interested in gunpowder weapons, so I want to learn about the situation of gunpowder weapons from the fifth brother." Zhao Yan said with a smile, this Cao Chong is a stable person, and he was born in the Cao family, there must be no problem with loyalty, maybe the matter of improving gunpowder can be handed over to this person.
