It was none other than Zhang Fei who ruined his good deeds, Liu Lan pretended to let him in as if he was fine, but his words were not so polite, but what kind of person is Zhang Fei, even if he has never eaten pork, he has seen a pig run, not to mention that he is still a pork seller, he can see Sima's weirdness and cat tiredness at a glance, and he can't point out why Sima is so angry, he must have ruined his good deeds. ~~x~

I snickered in my heart and entered the house, but I just looked at Hao Hao's eyes, which was called a ** playfulness, how could Sima say that it was also a person who had seen a big scene and pretended to be like nothing had happened, but Hao Hao couldn't stand this, a quiet girl was as thin as a piece of paper, and Zhang Fei looked at it like this, and the little bit of caution was all revealed, and at this moment I couldn't wait to find a crack in the ground to get into.

New hatred and old hatred, Hao Hao, who is full of shame and anger, can't say anything, can't explain anything, so he can only slash Sima, so that it changes in Zhang Fei's eyes, you must know that although he guessed that Sima and Hao Hao definitely didn't do anything good, but it is difficult to guess what they did, so at this time, he didn't regard Hao Hao's horizontal eyebrows as a scorn for Liu Lan, but mistakenly thought that the two were already in love, and even when he was present, he dared to openly send Qiubo.

Zhang Fei coughed dryly, he didn't want to continue to be this light bulb, he was busy explaining in the future, I heard that it was Ou Yejian who was looking for it, Liu Lan couldn't continue to rely on, and when Zhang Fei left, he would do some dirty things about getting on the bus first and then making up the ticket, and left with Zhang Fei and went to the workshop, which was extremely crowded at the moment, and it was possible to bump into people if he walked a little faster, fortunately, Yan Rou was building a new factory there, but this matter was not in a hurry. After all, it's winter, and construction can't be done. Now we are waiting for the spring to break ground.

found Ou Yejian, and didn't want Yan Rou to be there. Several people immediately returned to the barracks to discuss, this time Ou Yejian came to Liu Lan for the purpose of hearing that he wanted to increase the output of iron ore and build a new iron kiln to increase the amount of iron smelting, so Ou Yejian thought about whether he could give up the building of agricultural tools and build weapons instead, you must know that in the past, it was because the speed of iron smelting could not keep up, so he retreated to build agricultural tools for sale, since Sima wants to increase the amount of iron ore excavation and iron smelting, it is possible to sell weapons.

In Lulong, a farm tool can be sold for 200~300 yuan, even if the farm tools made by the steel filling method are sold well, they are expensive, and they are only 1,000 yuan. But if it is replaced with a fifty steel sword or a steel knife, the price is at least 7,000 yuan, if it is a hundred refining knife, it can be close to 12,000 or even sold for 15,000 yuan, of course, the iron consumption of weapons is greater, but compared to farm tools, the profit margin in this is too large, with the same iron training weapons than farm tools to earn 3,000 more money, virtually 10 more stone grains of rice. The profit in this is definitely something that Liu Lan can't ignore.

However, there are still some issues involved here, that is, whether the official will set restrictions, so everyone has to find Sima, who is the former Captain Lu Longsai anyway. Although he has a general relationship with the new Lu Longling, he can speak no matter what, if he comes forward. This difficulty may not be overcome.

"It's hard to convince Lu Longling, I need a reason to convince Lu Longling. Reason, understand. Can any of you give me this reason? Liu Lan looked at the crowd.

"Sima, look."

Ou Yejian winked at Yan Rou, Yan Rou stood up, first took out a ring-headed knife, and pulled out the sheath, this ring-headed knife is currently used by Lu Long's current county soldiers, as you can see, such a ring-headed knife has a slender body, about three feet, a straight ridge and a straight blade, one side is a blade, one side is a thick knife ridge, and the handle is cast into a flat ring. And a ring-headed knife like this, the price on the market in the Central Plains is 7,000 yuan, but it can be transported to Lulong, it is worth 10,000 yuan, and Sima, you look at this again, when Yan Rou pulled out another ring-head knife, Liu Lan's eyes were straight, in this era, if you want to say that the texture of the ring-head knife is the first to be refined by Nanyang, the reason for this should be that when Emperor Guangwu was Nanyang, Nanyang was too shou Du Shi to promote the effect of water drainage and iron smelting, and such a Nanyang ring-made hand knife has always been Liu Lan's dream, It's just that now with the dragon slaying knife created by Ou Yejian, it is not very rare, but he is not rare, but his subordinates are rare, you must know that this Nanyang ring head knife is the standard equipment of the Northern and Southern Army, even if the generals don't need it, it is also a big killing weapon in the hands of the soldiers.

"This is the first knife of the Nanyang Hundred Refining Ring?"

"It's not."

"Not? So what is this? Liu Lan asked.

"This is produced by our mine, and this is not a hundred refinements, but the use of the steel filling method, which is equivalent to fifty practices of ordinary craftsmen." Yan Rou, no, it can be said that the faces of the craftsmen who came with me all had a smug look on their faces.

"The process equivalent to the fifty refining of the ring head knife has trained the weapon of the hundred refining knives?" Liu Lan, who was taken aback, seemed to be listening to the Arabian Nights, he couldn't believe his ears, stretched out his little thumb and pulled it, and when he looked at everyone, Yan Rou once again said with certainty that Liu Lan believed that this qiē was true, and this is the process of fifty practices.

Liu Lan didn't dare to think about it anymore, of course, he would only equip the ring head knife created by the hundred refining process to his own troops, and he would not sell it for the time being, but even if he didn't sell it, the ring head knife of fifty practices was equivalent to the first knife of hundred refining rings, what kind of concept is this, that is to say, the original hundred refining knife only needs the price of fifty practice ring head knife or a slightly higher price to buy, such a reason, are you afraid that you can't convince Lu Longling?

Liu Lan smiled, he really didn't expect Yan Rou to give him this reason, but this reason was really impossible to refuse. And how big the profit margin is, he can see it, and Lu Longling can naturally see it, he doesn't believe that Lu Longling will give up such a profitable 'business'.

"However, for the creation of the Hundred Refining Knife, the current ordinary craftsmen, especially apprentices, are not yet able to get started, which is a blow to production efficiency." Yan Rou said: "So if Sima agrees, then in the next few days, I will ask the masters to introduce the process of making the ring head knife to the apprentices and ordinary craftsmen, and then let them smelt it themselves, and the speed will gradually increase." ”

How could Liu Lan disagree with this kind of good thing, but this matter is not in a hurry, at present, it is still mainly based on building farm tools in the mine Heifeng Mountain, the reason? Naturally, it was cold and could not be transported, so after the farm tools were built, he would wait for the results of his discussion with Lu Long Ling before deciding whether to build the ring head knife.
