When the four blacksmiths heard Qin Li speak like this, their mouths were pursed, and they looked very dissatisfied and angry. How could he steal the knife in Huang Tian and Zhou Fan's waists, and knew that Huang Tian and Zhou Fan were not easy to mess with, so he could barely hold back the anger in his heart and didn't dare to speak.

Don't look at the four blacksmiths who didn't believe what Qin Li said just now, but Huang Tian didn't believe it. Huang Tian knows Boss Qin very well, and every time Qin Li makes a new invention, he asks Huang Tian to give it to Emperor Zhengde. In Huang Tian's opinion, Qin Li is an extremely smart person. That's when you squint your eyes slightly, you can think of a good idea, and you can invent it.

This time, Boss Qin must have thought of the new and strange Dongdong again, and no one had seen it. After the four blacksmiths made it, they naturally mastered the technology, which was tantamount to a great good thing for them, but it meant that the wealth was rolling in, and this situation of cold court was probably going to end completely.

Huang Tian expected that he was not wrong at all, Qin Li quickly asked the old man to get a pen and paper, and Qin Li carefully drew a structural diagram of a heating stove in later generations.

Today in Emperor Zhengde's leopard room, Qin Li saw the charcoal basin used by Zhengde with his own eyes, and the smoke coming out of the charcoal basin really smoked to death. Emperor Zhengde also seems to have made four in the bedroom. OMG! How much carbon dioxide, carbon monoxide and other toxic gases will be in there?

Emperor Zhengde originally had lung disease, but now under the smoke coming out of these four charcoal basins, can the disease be cured? Not only will it not get better, but it will continue to worsen if it continues to develop like this, and Zhengde's life will soon run out of oil and run out.

When Qin Li saw the charcoal basin at that time, he thought of the heating stove of later generations.

In the Ming Dynasty, the materials needed to make the heating stove were fully equipped, but no one had yet invented that new thing.

There are heating stoves, and naturally there are chimneys. The chimney is even simpler.

The four blacksmiths got together and carefully figured out the drawings drawn by Qin Li, saying that they were all old blacksmiths for many years, and they were very clever in the blacksmithing industry. The four of them just looked at the tea time, and the eyes of the four of them lit up.

Immediately, they understood the meaning of what Qin Li had just said.

Qin Li didn't lie to them, let alone fool them, and he wasn't making things difficult for them. Qin Li sincerely wants to help them!

The old man's eyes, which had been a little dizzy, became very bright, as if he was more than ten years younger, and he asked anxiously, "So this old man wants to give us the patent for this heating stove and chimney?" ”

It is said that after Qin Li fooled Emperor Zhengde into implementing the patent law in the Ming Dynasty, the modern word patent became popular in the Ming Dynasty. Coupled with Qin Li's teaching method of different grades and disciplines, it has broadened people's thinking and horizons, and some small inventions have begun to appear, and they have applied for patents in the household department.

Qin Li smiled slightly and said, "Not only is it to let you own the patent law for this heating stove and chimney, but I also want to let your heating stove and chimney sell for a good price!" I will send this heating stove you made for me to the palace, as long as the emperor uses it and says yes, this patent will be done. Hehe! At that time, it will be difficult for the four of you not to get rich! ”

Boom! It's really pie in the sky, and it just happened to hit your head! What else do the four blacksmiths have to suspect now, and what else is there to be wronged? They were in a good mood and excited to the extreme.

The four of them hurriedly knelt down and kowtowed to Qin Li.

Qin Li enjoyed the scene of the people kneeling down very much, but the four bitter old men in front of him knelt down, Qin Li didn't know what was going on, and there was no longer that kind of joy in his heart, but sour.

The people's requirements are very low, and sometimes they don't need you to give them a lot, just a few simple kind words, or promises that can't be fulfilled at all, and they are very satisfied and grateful to you.

In fact, when it comes to giving them great benefits, their way of expressing it is also very simple. But this is such a very simple way of gratitude that is the most simple, sincere, and heartfelt. In fact, if they are asked to express it in other ways, they really have no other way, because their lives are difficult, and they can no longer get anything suitable except to bow and kowtow.

Qin Li picked up the four blacksmiths without hesitation, but said with a very heavy face, "The four old men don't have to thank me, whether you can win the patent for the production of this heating stove still depends on yourself." I'm just waiting here for you to make the stove I want. If I can't see it, then I have no choice but to look elsewhere! ”

The four blacksmiths hurriedly nodded yes.

Then there is a division of labor for blasting and burning iron, and they are busy in an orderly manner.

Their movements are swift, their movements are skillful, and their eyes are bright. All this reflects their confidence that they must win the patent for this heating stove and chimney.

It's no wonder that in fact, there are no more blacksmith shops left in the capital at this time. The few companies that are actually connected to the government and the military are in touch with each other, and they make some weapons, which can completely get by. But these four common people blacksmiths have nothing to do with each other, and can only eat with their true skills.

Too many facts have proved that sometimes it is absolutely impossible to eat with real skills, and you will not be able to eat enough, or even eat. For example, the four blacksmiths in front of you.

Qin Li sat on the side and watched carefully, after all, it was the first heating stove that appeared in Daming, after all, it was to be given to the emperor today, this must be done well, it must be practical, and everyone in Daming must realize its value and use its benefits at a glance.

An hour and a half passed, and it was slowly getting dark, and Qin Li was watching them busy carefully.

Another hour has passed, the sky is already full of stars, and thousands of lights are on, Qin Li is still watching.

……

The four blacksmiths were busy for three and a half hours, and finally made the first heating stove and chimney of the Ming Dynasty. Qin Li patted the shoulders of several old blacksmiths with a smile, and said with satisfaction, "Okay, this is exactly what I want!" Hehe! Tomorrow you will be able to produce in large quantities. I'm going to let the whole of Beijing use this stove this winter! ”

Qin Li was full of confidence when he spoke, but the four blacksmiths listened with sad faces.

How much iron does it take to produce it in large quantities? Although the imperial court is not too strict with the management of iron, it also needs raw materials for mass production of heating stoves, right? How can four blacksmiths produce a large number of raw materials without raw materials?

Qin Li had already guessed their thoughts, and when he reached into his arms, he took out five taels of gold and handed it to the old man who was the leader. The old man was inexplicably grateful, and was about to kneel down to thank him, but Qin Li said, "Don't thank me, this is my investment, and I used five taels of gold to buy shares." I want 40% of the profit of this heating stove! (To be continued.) )
