Yunyi doesn't like to deal with things, but he still has the necessary knowledge of his own industry, on the one hand, to prevent his subordinates from cheating, and on the other hand, to sketch the blueprint in his heart.

Opposite Yunyi, the seven old blacksmiths looked at the drawings in front of them, the swarthy faces that had been roasted because of the perennial iron, were now red, they were excited, they had never seen such drawings.

Yunyi only draws one part on each drawing, but there are three parts on a drawing, which is three views: the main view, the top view, and the side view.

Using three views to outline a part can most intuitively express the parts that Yunyi wants to make to the blacksmiths.

Blacksmiths don't use drawings most of the time, but it doesn't mean that they don't need to use drawings, like when building ordinary farm tools, it is impossible to use drawings at all, because the appearance of farm tools has been memorized by blacksmiths, but sometimes there are people who take drawings to let blacksmiths create special things, and blacksmiths need to build according to drawings.

It's just that the drawings that blacksmiths have seen are so simple, only a simple sketch, sometimes there is not even a size, and the blacksmiths have seen three views for the first time, and the drawing lines should be straight and never curved, and the bend should never be straight, and the size of each part is clearly marked.

Getting such a drawing, the blacksmiths only looked at it a few times, and already sketched a complete part in their minds, which is really an incredible thing.

The specifications of the parts are different, and the difficulty of building is also different, but the skills of the seven old blacksmiths are very good, even if they can't reach the "master", they are outstanding, after reading all the drawings, the old blacksmith found that some of the parts are difficult to build, but they discussed with each other for a few words and came to a conclusion: the first time you may not be able to build, you can build it after a few more experiments.

That is to say, as long as the blacksmiths are given time, these parts of the steam engine can be built by the blacksmiths, and you must know that there are parts of the steam engine that need to be sealed, so you can never underestimate the command of "them".

Even in Yunyi's previous life, when the steam engine first came out, was it not handmade? And those firearms, which are also handmade.

The steam engine is only the first step of Yunyi's plan, as long as there is a steam engine, Yunyi can use the steam engine to mine mines, and can also manufacture steam-powered machine tools and vehicles, at that time Yunhua Yun's will have earth-shaking changes, of course, after these things are manufactured, they must be hidden, after all, the current Yunhua Yun's clan is too weak, not to mention that it can't confront the Dali Empire, and even the seven surnames and twelve clans of the Dali Empire can't deal with it.

Just when Yun Yi was still in the manor outside the city, Yun Yi's third uncle Yun Yuankai's mansion ushered in waves of guests, which can be described as a surplus of guests, and the forces behind these guests were more terrifying than the other, countless times larger than the Yunhua Yun clan who lived in a single place, Yun Yuankai had to push away the things on his body and go back to the mansion to receive the guests in person.

Today is the sixteenth day of the first lunar month, just after the Shangyuan Festival (Lantern Festival), this year is also considered to be in the past, but in some areas, the New Year will last until the second day of February.

During the Chinese New Year, everyone has things to be busy with, and it is not suitable to talk about things, so on the first day of the new year, representatives of various forces gathered in Yunhua County, and people from different forces met each other, although they talked and laughed on the surface, but they were infinitely vigilant behind the scenes, and now they were all opponents, it was up to them to see who could get what they needed from the Yun clan.

But why did they come here?

At present, there are only three things that can make outsiders look at them:

The first is the "Yun's Salt Making Law", with it, all forces close to the sea can obtain a large amount of white salt, but the Yun Clan has spread the "Yun's Salt Making Law" to the world, not only the various forces of the Dali Empire know the specific content of the "Yun's Salt Making Law", and now the "Yun's Salt Making Law" is widely spread in the land of China, and people with a little strength can easily obtain the "Yun's Salt Making Law";

The second is the silver mine that the Yun clan has begun to mine, although the value of silver is not as good as gold, but it is not much worse, after all, the content of silver is more than gold, and the quantity can represent everything, but the forces that came to Yunhua County today are not only those of the Dali Empire, but also those outside the Dali Empire, what is the use of the silver mines located in Yunhua County by foreign forces, and they are not eyed by the income of the silver mines;

And the third is Yunhua paper, Yunhua paper is Yunyi's private property, and it can be regarded as Yun's industry, no one needs to speak, Yun Yuankai guessed that they came for Yunhua paper.

Yunhua Paper is a gold mine, no, not only a gold mine, Yunhua Paper can be called a cash cow or cornucopia, which can continuously generate a huge amount of money.

Take Gao Xun paper as an example, a one-foot square Gao Xun paper costs 1 silver, although its manufacturing cost is high, but it does not exceed 50 copper, the annual consumption of Gao Xun paper in the Dali Empire is more than 100 million, of which the income is more than 500,000 gold, which is a huge number.

A high search paper technology, hooked up a big net, this big net will not only cover the Dali Empire, but also cover other countries on the land of Shenzhou, the interests are moving, not to mention such a huge number, in the Dali Empire to produce Gao Xun paper forces are definitely not more than ten, they will sell the entire Dali Empire Gao Xun paper, because Gao Xun paper forms an alliance to control the price of Gao Xun paper, and make high profits.

Nowadays, Yunhua paper with better quality than Gaoxun paper has appeared, although various forces do not know the cost of Yunhua paper, but only by virtue of the quality of Yunhua paper, Yunhua paper stands out and seriously squeezes the market of Gaoxun paper, which is unbearable for the original Gaoxun paper interest alliance.

However, because the production of Yunhua paper is limited, and the Yunhua Yun clan is valued by the old emperor of the Dali Empire, those forces related to Gao Xun Paper have not yet started with the Yunhua Yun clan, if they really attack the Yunhua Yun clan, with the current strength of the Yunhua Yun clan, how can they resist the enemy who is eyeing the tiger.

Just after the New Year, the various forces in the Gao Xun Paper Interest Alliance of the Dali Empire came to the door, and they wanted to obtain the technology of Yunhua Paper from the Yun Clan, or let the Yun Clan join the Paper Industry Interest Alliance, so as not to have too much impact on the various forces in the Gao Xun Paper Interest Alliance.

In addition to the people of the Gaoxun Paper Interest Alliance, some other forces that are greedy for the huge interests of the paper industry also want to obtain Yunhua Paper technology from Yun's hands, and want to snatch food from the Gaoxun Paper Interest Alliance, which means that these forces have the strength that is not inferior to the Gaoxun Paper Interest Alliance, and a dragon battle is about to begin.

However, from the day he took out the papermaking technique, Yunyi had already expected such a day, but it was only a matter of time.
