After briefly saying a few more things, Xiang Han asked a few people to go about their own business.

However, the other three left, but Guo Jia stayed.

"What? Is there anything else to do with Fengxiao? Xiang Han asked with a slight smile.

"Lord, ...... Jia Xu?" Although he heard Xiang Han say that, Guo Jia still had doubts about Jia Xu, because Guo Jia could see that Jia Xu's city government was too deep.

"You don't have to worry about this, I know what you're thinking, but I can tell you, it's okay!" Xiang Han smiled slightly, reached out and patted Guo Jia's shoulder, "You kid, you're in good health now!" ”

"Hehe, during the absence of the lord, Jia and Mr. Yuanhua learned a set of things called five poultry plays, and it is said that you can strengthen your body if you play too much!" Guo Jia said with a smile.

"Oh? Hua Tuo even handed over the five poultry plays to you? Xiang Han was slightly stunned.

"What's more, it's not just me, Zhicai, and Gongda are all learning, but also the little apprentice of the lord, Gongjin, is also learning!" Guo Jiadao.

"Hehe, this is not bad, much better than you drank flower wine all day before!" Xiang Han smiled.

"Lord, can we stop talking about this? That place, Jia is no longer gone! Guo Jia said with a bitter face.

"It's easy to say, but I heard that you have been very close to Zilong's sister and Xiaoyu recently! Don't you two ......? Speaking of this, Xiang Han laughed evilly.

"Ahem......" Hearing Xiang Han mention this, Guo Jia suddenly blushed and coughed lightly twice, "Lord, the weather is good today, the weather is good!" ”

After saying that, Guo Jia flew away as if he were flying!

"Hahahaha!" Xiang Han laughed.

"It is really not easy to make Guo Jia, the prodigal son, change his evil ways and return to the right, Xiaoyu, Xiaoyu, it's really not simple!" The corners of Xiang Han's mouth raised slightly, picked up three pieces of cloth in the study, left the Thorn Mansion, and went straight to the blacksmith shop.

[Option 1: Inspect a circle, explain the task, reward: two apples]

[Option 2: Adjust the production operation mode, implement the assembly line, reward: four apples]

Hey, hey, hey!

Xiang Han was a little speechless, you can't eat all the apples, do you have to give them to me?

Shaking his head, Xiang Han stepped into the blacksmith shop.

The scale of the current blacksmith shop is okay, but the efficiency is a little low, each blacksmith is in charge of a stall, each crafting their own things, seemingly not interfering with each other, and everyone's iron-striking speed is not bad.

Of course, there are also a few apprentices next to each master to learn or help.

Seeing Xiang Han come in, all the craftsmen stopped.

"Okay, don't be polite!" Xiang Han waved his hand, "Who among you is the head?" ”

A few people, you look at me, I look at you, it seems that they have not thought about such a question, who is the head? They didn't know that the best craftsman among them was Master Tian.

Seeing that everyone's eyes were on Master Tian, Xiang Han smiled slightly: "This master, what is your name?" ”

"Lord Qiyu, the old man's name is Tian Yu, and he has been striking iron for more than 20 years!" Tian Yu said.

"Master Tian, all of you blacksmiths work at the same time, if you want to make a thousand steel knives, how long will it take?" Xiang Han asked with a slight smile.

"This ...... Steel knives are relatively troublesome to build, old decay can only build two or three a day, most blacksmiths are also at this level, we have a total of twenty blacksmiths, it is 40 a day, so it will take nearly a month to create a thousand! While calculating and chattering, Tian Yu finally gave the answer.

"So, tell me, how many steps does it take to build a steel knife?" Xiang Han smiled slightly.

"First you have to boil out the molten iron, then cast, then strike the iron, quench, make the knife handle, put the knife handle, and that's roughly the steps." Tian Yu was a little puzzled, what did Xiang Han want to do for these?

"Hehe, let's not count the links of boiling molten iron and casting, just let you only strike iron every day, how many steel knives can you complete?" Xiang Han asked with a slight smile.

"This ......" Tian Yu frowned and thought for a while, "how can there be hundreds of handfuls a day." ”

"What about having you quench only every day?" Xiang Han asked again.

"Quenching is simple, you can make three or four hundred a day!" Tian Yu replied without thinking about it.

"How many knives can you make a day?" Xiang Han asked again.

"The knife handle process is not so difficult, you can make one in the time of one stick of incense, and the installation is not too much, and there are hundreds of them a day!" Tian Yu thought for a while.

"Okay, I'll disperse you masters, a few of you are responsible for boiling molten iron every day, and a few of you are only responsible for casting every day, and you are responsible for striking iron......" Xiang Han assigned the tasks of these blacksmiths one by one.

"In that case, how many steel knives do you think you can make in a day?" Xiang Han asked with a slight smile.

"This ...... Theoretically, hundreds of them can be made, and even hundreds of them can be made if there are more people, but in practice it is definitely not feasible! Tian Yu shook his head and said.

Of course, the rest of the blacksmiths shook their heads as well.

"Why is that?" Xiang Han asked suspiciously.

"Lord, each of us has our own size specifications, although they are similar, but if we really do this, it is very likely that the installation of the blade and the handle is not suitable, or the time for striking iron and quenching is not suitable, such a knife is not able to go to the battlefield!" Tian Yu voiced his concerns.

"Huh." Xiang Han chuckled and shook his head, "It's up to you!" ”

"Look at me?" Tian Yu was puzzled and stretched out his finger to point at himself.

"Yes, I want you to set a construction process specification and a standard size! The length of the steel knife, the width of the blade, the size of the knife handle, and so on, should be written in detail, and then distributed to the hands of the people at each step, everyone strictly follows the construction process to construct, and the size must not be wrong, in this way, do you think, the problems you just mentioned, or the problem? Xiang Han smiled and said his thoughts.

"Not a problem! Not a problem! Xiang Han said a few simple words, and Tian Yu understood everything! The lord is a great talent! The lord is a great talent! ”

"This is similar, I call it an assembly line, you implement it as soon as possible, and transform this blacksmith shop into what the assembly line needs, I think you should be able to understand!" Xiang Han said.

"In addition, when the assembly line officially starts, you masters can recruit a large number of apprentices, and some people may ask him to build a knife, he can't build it well, but he is fully capable of one of the steps! At that time, one of you masters could be in charge of an assembly line. Xiang Han said.

"Yes! Be! Tian Yu's expression was excited, he couldn't imagine how big the blacksmith shop would be at that time!

"Implement it as soon as possible, and this task will be handed over to you. Then, I have something for you to build. Xiang Han said.

"Yes!" Tian Yu nodded excitedly.
