In the end, they ate a total of nearly ten roast lamb legs, and they all lay on the ground without moving, that's it, Bai Fuli was still shouting to eat, and was despised by Chu Nan.

The next day, Chu Nan called Mu Du and gave him how to use these spices, and finally asked Bai He to help write it down and mark how to use it, so that he could pass it on and let all the people in the clan use it.

Soon, the entire Tianhuo tribe was filled with a spicy, spicy smell of barbecue.

After Chu Nan and the others finished eating the spicy roast leg of mutton, they began to cook the meat again, adding these spices to remove the smell, and the final taste was no worse than the barbecue.

The people in the Ministry of Industry really couldn't understand the purpose of Chu Nan to let them observe the boiling water, and the stone could only come to ask for advice in person, there was no way, it couldn't be delayed forever.

Chu Nan did not reprimand the other party, nor did he rush to explain, but asked Shi Shi to take him around the Tianhuo Industrial Park, intending to understand the general situation of industrial development first.

After looking at it this time, I found that it was still in the most rudimentary stage, and after losing his guidance, there was basically no progress, and everyone spent their efforts on meticulous craftsmanship and improving quality, and even the improvement of tools did not happen, which made Chu Nan a little disappointed.

"It seems that I am too anxious for quick success, industrial accumulation is necessary, without strong accumulation, it is like a high-rise building without a solid foundation, even if it is built, it will not last long, it will eventually collapse, or take it slowly." Chu Nan frowned slightly, but didn't say anything.

Finally, there is a production workshop, where people are producing wooden chairs and tables, all of them are using tools made of steel, axes, saws, chisels, planers, etc., to name a few.

These people are very slow and careful, because they have to calculate each size, and if the size is not right, the object will not be strong at all, and it will fall apart in a flash.

"Haven't you considered reinforcing with nails?" Chu Nan asked with a frown.

"Nails? What's that? "I don't know the production workers, even Mu Du is also a face of the blindfold, nails? What? Never heard of it?

Chu Nan smiled bitterly and said, "Okay, I'll explain it to you." ”

Chu Nan found a thin iron rod one inch long, and then slowly polished it, sharpened one end, and smoothed the other end, and then gently smacked it into one of the joints of the chair with an iron hammer, and finally confirmed, before he said: "Okay, you guys try, do you explain the stool that comes out of this?" ”

This was originally a qualified stool, and if it was nailed by Chu Nan, it would be even stronger, and when he nailed all the joints with nails, he handed the chair to the workers standing next to him, and asked them to see how good the quality was compared to the original.

These people tried it, and sure enough, it was much stronger, and the requirements for the interface were not too strict, and it was still very stable to sit on.

Chu Nan nailed two iron nails in each interface, so that there would be no shaking, even if the interface was not tight, because there were two iron nails, it could also ensure the firmness of the chair, and in the same way, other wooden supplies, as long as there was an interface, could be reinforced with iron nails.

It's just how to mass produce iron nails, this is another problem, it can be said that in industrialization, a problem is set of problems, and they are connected to each other, which requires every link to be connected, otherwise, it will slow down.

"As for how to quickly produce iron nails, you give me a way, be fast, you can also brainstorm other things, break the inertial thinking, and innovate, don't always think about how I do it, you have to think about how you want to do it, train industrial talents, train senior technicians, you know?" Chu Nan patiently guided.

"Brainstorming? Habitual thinking? Innovation? Listening to the new noun that came out of Chu Nan's mouth, everyone knew that this was a new invention of their own chief, although they didn't know the specific meaning, they could guess it.

"Where do we start?" Not to mention the others, even the stones are confused.

"The small ones are not easy to do, we can make them bigger, so that they are easier to operate, and the models that the chief said, we can make more models, and then let the molten iron be poured on them, and then slowly polished, so that it should be able to be mass-produced." A young man hid behind and said cautiously.

"Oh? What's your name? Something interesting. Chu Nan's heart jumped, and the secret path finally had an enlightenment.

"This is a newcomer we just recruited, called Tie Niu, don't look at the five big and three coarse, his mind is very delicate, and he has a lot of ideas." Stone listened proudly, puffed up his chest and continued, "I've been teaching something lately, and I'm going to recommend this person to the chief in a few days." ”

"Well, Iron Bull? Come here, let me ask you again, if you make a model and can mass-produce iron nail embryos, how can you polish them quickly? If you polish one by one, the speed is still not fast enough. Chu Nan looked at the big man in front of him, who was nearly one meter taller than himself, and was a little speechless, although he was now more than two meters tall, he still belonged to the small man in the tribe.

Tie Niu scratched his head and said: "I said it wrong, don't laugh at me, chief, I have also thought about this matter, many things are the same, for example, the hydraulic blower for the iron-making furnace in our industrial zone, and the grinding of iron nails can also borrow this principle." ”

Speaking of this, Tie Niu scratched his head and looked at Chu Nan with some embarrassment, afraid that Chu Nan would laugh at him and not let him continue.

"Don't stop, go on, maybe I've already guessed what you're going to do, but I want you to say it yourself, well, so let the others cooperate with you and make an experimental sample to see." Chu Nan clapped his hands for the last time and gave an order.

Tie Niu glanced at the stone, and the stone was a little angry and said, "What do you think I do?" If the chief asks you to do it, you will do it, this is the opportunity given to you by the chief, and you can't behave well? It's really angry with the old man, everyone else is going to act quickly and cooperate with Tie Niu. ”

"Yes." The others immediately agreed, looking at Tie Niu with blank eyes.

Being watched by so many people, Tie Niu was a little embarrassed, and when he saw Chu Nan's encouraging eyes, he immediately took a few deep breaths and said, "Everyone first help me install a hydraulic dumper, and then find me a thinner grinding wheel." ”

These people are tech-savvy, and once they are told what they want to do, they will be much faster, recruit some workers, and start installing, because the hydraulic dumper has ready-made, just build a bracket by the river, put the waterwheel on it, and then drive the axle wheel with water.

The hydraulic overturn rotates very quickly under the drive of the water flow, especially the iron bull let people take two wheels with a circumference of 20 to 1, and carry out another processing, which can make the bearing with a thin grinding wheel rotate quickly, and it is very convenient to polish the iron nails.
