Turning around and going to the front of the coals, Fan Yu picked a fist-sized piece of coal from it, held it in his hand, and walked back.

Xu Shou, Zhang Tangqing and Liu Zhen all watched Fan Yu pick up coal blocks, but they didn't know what his intentions were.

"Master Hou has an idea?" Zhang Tangqing hurriedly asked.

Fan Yu nodded, "I have some ideas, but I have to try to know if I can succeed." ”

Liu Zhen was a little unconvinced: "Hou Ye Mo is joking with me, there are hundreds of people in the Iron Yard, and they haven't come up with a good way since Song Liguo for decades." ”

This means that so many people have no way for such a long time, how can you have a way in a moment.

Xu Shou also didn't believe it, but he wanted to give Fan Yu a step, so he said: "Master Hou is a nobleman, how can he be delayed in such a trivial matter, it is better to forget it." It's not early, and there is a Tongxin store outside the west workshop. Among them, the roasted lamb is crispy on the outside and soft on the inside, and it is paired with the store's unique lychee stuffing, which has a unique flavor. If you don't want to be the official, please have a big meal with Master Hou and Brother Zhang. ”

Fan Yu raised his eyes and glanced at this Xu Shou, it seems that this Tanhualang is also one of our foodies. Although he was a little excited, Fan Yu didn't want to give up halfway now. At least you have to solve the problem in front of you before you have the heart to solve your cravings.

Otherwise, if you can't go up or down, won't it make people uncomfortable.

Waving his hand, Fan Yu shook the coal in his hand and said, "Master Liu, you all add coal directly to the furnace when you make iron." ”

"Charcoal is more resistant to burning than charcoal, so naturally it is added to the furnace to burn, otherwise what?" Liu Zhen didn't understand what Fan Yu meant.

Fan Yu laughed and said, "If it is directly burned to smelt iron, I'm afraid it will be a little difficult to use." If you want to increase the temperature of the furnace, you can burn the charcoal into charcoal first, and then put it into the furnace to burn. ”

Zhang Tangqing raised his eyebrows first and said, "Master Hou, this is charcoal, if it is burned again, it will not become ashes." Throw the ash into the furnace, I'm afraid it won't ignite. ”

Liu Zhen also nodded and said: "That's right, if you burn it first, it will turn to ashes." ”

Xu Shou, who wanted to help Fan Yu play a round, couldn't interject at this time. He only felt that this Hou Ye had made himself so embarrassed, but he was a little stubborn at a young age.

"I mean, it's like making charcoal. The coals are smoldered in the kiln for several days, then watered and extinguished. If it is not burned to ash, it can be called coke, and it can be used to make iron. Fan Yu raised the coal in his hand and continued: "Charcoal has fewer impurities than firewood, and the temperature is higher than that of firewood. In the same way, coke should also have fewer impurities than charcoal, and the temperature should be higher than that of charcoal. ”

Xu Shou and Zhang Tangqing were thoughtful, pondering the meaning of Fan Yu's words.

Liu Zhen suddenly froze and didn't move, and only after a while did he pat his thigh and said, "Hou Ye's words woke up the dreamer!" If this coke can really be fired, it will definitely be as Hou Ye said, and the impurities of the iron ingots will be much less. I'll let people try to burn some, if it works, Hou Ye is the benefactor of all the blacksmiths in the Great Song Dynasty! The weapons and armor of my Great Song Dynasty will definitely go to the next level! ”

Fan Yu laughed and said: "It's not so easy to burn coke, and the cost will be increased." ”

"Value!" Liu Zhen was only thinking about how to smelt iron with coke, and said with a happy face: "If you can really reduce the impurities in the iron, the weapon will be more durable." As a result, it also equals a loss saving. Compared to that, the money for burning coke is nothing. ”

Xu Shou and Zhang Tangqing glanced at each other, they didn't expect that Fan Yu would come to this iron yard and make the craftsman Liu Zhen ecstatic with a few words.

Without waiting for Fan Yu to say anything, Liu Zhen left on his own, and he didn't even say goodbye.

Fan Yu couldn't help but shake his head and smile when he saw Liu Zhen leaving in a hurry: "Although this Master Liu has a straightforward and sloppy temperament, he is extremely focused. If you don't focus so much, I'm afraid you won't be able to become a leader in iron smelting. ”

Zhang Tangqing also echoed: "It's a pity, but he became a craftsman." If you are so focused on studying, you must be a poor scholar. ”

"Talent is like that, and you can't force it. If Brother Zhang asks him to study, I'm afraid that he will delay a master. Such people have what they love, and they will not be able to do it in another way. Xu Shou also followed.

"By the way, Xu Tanhua, where is the Tongxin store?" Fan Yu touched his stomach and said, "Since you're here, wouldn't it be a pity if you don't taste it." can be respected by Tanhualang, it must taste extraordinary. ”

Zhang Tangqing laughed and said, "Yes, I was about to disturb Tanhualang." ”

Xu Shou said in his heart, he originally thought that these two people were polite, but he didn't expect to be worried.

"Please come with me." Xu Shou stretched out his hand to lead the two of them, and he should lead the way first.

In the next few days, Fan Yu went out early and returned late every day. There are many workshops in the Ordnance Factory, and it takes seven or eight days to inspect two or three places a day. Because he was busy, he didn't notice that Zhanzhao had disappeared in the past few days.

It wasn't until the morning of the sixth night when he returned home that Fan Yu remembered to ask Wang Xiaoding Zhan where his eldest brother had gone.

Wang Xiaoding is older than the Chen sisters, and now he also has the consciousness of being a housekeeper in the Hou Mansion, and Fan Yu is not in the house, so everything he can clean up will be cleaned up.

Hearing Fan Yu's question, Wang Xiaoding replied: "Uncle Zhan told me the day before yesterday that he was going to go to Yaowu Tower to perform martial arts, and he won't live in the Hou Mansion for the past few days. ”

"Brother Zhan doesn't live in the mansion, but why don't you tell me?" Fan Yu said a little angrily.

"This is what Uncle Zhan ordered, he said that Hou Ye has been busy with official business recently, and it is not too late to talk about some small things when Hou Ye is free." Wang Xiaoding hurriedly argued.

When Fan Yu heard it, it turned out that it was Zhanzhao's own order, and he lost his temper. It's been a few days, and I don't know what happened to Brother Zhan's martial arts.

Just thinking about this, I heard a sound of footsteps outside the door, but it was Zhanzhao who came back.

Fan Yu hurriedly got up to greet him, hugged his fist at Zhan Zhao and said, "Brother Zhan has been performing martial arts for the past few days, and he didn't let Wang Xiaoding tell me, but he neglected Brother Zhan." ”

"I saw that you went out early and returned late, so I told him not to delay you." Zhan Zhao's mood was obviously good, and his face was bright.

"Looking at Brother Zhan's proud appearance, it is obvious that the martial arts performance in Yaowu Building is very smooth, right?" Fan Yu stretched out his hand to ask Zhanzhao to sit down, and then asked for details.

Zhan Zhao heard Fan Yu ask, and was scratching his itch, so he laughed and said: "This time is quite smooth, I have been preparing in Kaifeng Mansion for the past few days, and until today, I went to Yaowu Tower with Bao Governor's Mansion." The official family came to Yaowu Tower in person, but it was time to show his skills. ”

Fan Yu heard Zhan Zhao say this, but he only said half of it, and couldn't help asking: "Brother Zhan, don't sell Guanzi, tell the younger brother quickly, what is the reaction of the official family after watching you perform martial arts." ”

"It's also Zhan's excellent skills, swordsmanship, archery, and horse step kung fu are not comparable to ordinary generals." When Zhan Zhao said this, he took out a letter of confession and seal, "Therefore, the official royal family personally sealed Zhan Mouwei and brought imperial equipment." ”
