Among the various forces that have entered Yunhua County, there is a force that is different, this force is still the in-laws of the Yun family, but now it is a strange road, and this force is the Dingxiang Shangguan clan in the twelve clans.

The leader of the Shangguan clan is named Shangguan Hongzhen, the younger brother of Shangguan Hongbo, the current head of the Shangguan clan, and is one of the important figures of the Shangguan clan, mainly responsible for things outside the Shangguan clan, and often runs around outside.

It stands to reason that Shangguan Hongzhen is still the uncle of Yunyi's wife Shangguan Yuling, if the previous thing does not happen, Shangguan will become the best friend of the Yun family, and this time Yunhua Paper should have a share of Shangguan's share in the distribution of interests, which can bring more than 50,000 gold to Shangguan's every year.

It's a pity that the Shangguan clan died by himself, for the sake of a daughter who has a great possibility of becoming a congenital martial artist, he gave up the friendship of the Yun clan, and now I don't know if he has regretted it, the annual income of 50,000 gold or a congenital martial artist I don't know which is more important, not to mention that women are born weaker than men in martial arts because of physical reasons, and it is difficult to have a female congenital martial artist among the five innate martial artists.

Although Shangguan Hongzhen is Shangguan Yuling's uncle, he has met many times before, but because Shangguan Hongzhen has only a handful of words to Shangguan Yuling, Shangguan Yuling saluted Shangguan Hongzhen when she saw him, and many times she was ignored, and the reason was Shangguan Yuling's status as a concubine, Shangguan Yuling, who did not have much martial arts talent, had a very low status in the Shangguan clan, even lower than the children of the side branches of the Shangguan clan.

Shangguan Hongzhen understood the relationship between the Shangguan clan and the Yun clan, so after coming to Yunhua County, he didn't dislike people to visit Yun Yuankai, let alone go to see his niece, but just stayed in the inn and prepared to fish in troubled waters.

The various forces have united, Shangguan Hongzhen also wants to cooperate with other forces, and even visited some forces, but there is no result, even if it is a force that has a good relationship with Shangguan, he did not give Shangguan any answer, because the major forces know the relationship between Shangguan and Yun, Shangguan has made Yun lose so much face, if any force cooperates with Shangguan, then there is really no chance to get Yunhua paper technology, everyone understands this truth, Shangguan Hongzhen also understands, However, Shangguan Hongzhen still had the attitude of trying to test other forces, and the final result made Shangguan Hongzhen a little angry.

"Why bother in the first place?" This is the idea of the various forces.

As one of the twelve clans, the Dingxiang Shangguan clan has been isolated by the major forces, and before the Yunhua paper technology is not conclusive, no one will have too much contact with the Shangguan clan, so as not to touch the Yun's moldy head.

On the second day, more forces came to Yunhua County, of which the local forces of the Dali Empire accounted for most of them, and the rest were forces spanning two or more countries.

Yun Yuankai took the time to deal with the affairs of the family and Yunhua County briefly, and was busy receiving guests from all walks of life, but Yun Yuankai's recovery of the guests was still those words yesterday: "Yunhua paper is very important to the Yun family, it is not for me to decide alone, please wait a few days, our Yun family will discuss it." ”

With so many forces coming, the Yunhua County Town Inn was overcrowded.

Yun Yi at home received a gift from a manor outside the city, opened the package and saw that it was a few steam engine parts, which were relatively easy to build, and the old blacksmiths built them overnight, and finally made a few copies, and now sent them to Yunfu.

Yunyi's right hand gently picked up a small dark part, and his left hand rubbed it on the surface of the part a few times to feel the metallic texture of the part.

The specifications of the parts are about the same as those marked on the Yunyi drawings, and there will be a few points of difference, which is not a big problem for the first steam engine, and the problem of accuracy will be paid attention to in the future.

The specifications of the parts are qualified, but it does not mean that the parts are qualified, the most important thing is the quality of the parts, once the quality is unqualified, when the steam engine is used, the steam engine is easy to have problems, and it is more likely to cause the explosion of the steam engine boiler, which is dangerous.

Next, Yunyi began to test the quality of the parts, broke the parts with both hands, smashed the parts to the ground with different forces, slashed, stabbed the parts with a sword, washed, burned, and so on.

The reason for the unqualified parts Yunyi also found, the problem lies in the material of the parts, the material of the parts is that Yun's people bought a batch of pig iron from Zezhou, the blacksmiths used this batch of pig iron to build, there are more impurities in the pig iron, although some impurities are removed after forging, there are still more impurities left, although the parts made of such materials can be used, but the life must not be too long.

Pig iron is iron that has just been made from iron ore, and there is better iron than pig iron - refined iron, and there is no more of it, and even the parts made of refined iron will not be qualified, and Yun's cannot buy much refined iron.

The swords used by the warriors are made of fine iron, and the high-quality swords are heated and forged more than 100 times by the fine iron, one forged and one weighed and one light, until the catties are not reduced, that is, hundreds of forged steel, and better is thousands of forged steel, ten thousand forged steel, such a sword can be called a divine weapon.

It's just that all kinds of forging steel are time-consuming and labor-intensive, how can they be used to create parts on a large scale.

Yunyi has a headache, the best way to solve this problem is to mine iron ore and make iron and steel by himself, so as to solve the quality problem of parts.

Mining iron ore to establish a steel plant is also in Yunyi's plan, but the recent movement of Yun's is too big, and the matter of Yunhua paper now, after the matter of Yunhua paper is resolved, Yun's should be silent for a while, and the whole movement is too big and too much will be detrimental to Yun's future development.

Yunyi originally wanted to let the Yun family be silent for a while before mining iron ore, but now he can't care so much, there is just the matter of Yunhua paper in front, compared to Yunhua paper, mining iron ore is just a small matter, all forces will focus on Yunhua paper, and there will not be too many people who pay attention to iron ore.

So Yun Yi and Yun Yuankai talked for a while, and then Yun Jie left Yunhua County with the paperwork and went to the imperial capital Xinping, nominally the iron ore was mined by the Yun family, but in fact, Yun Yi paid for the iron ore mining at his own expense.

Although it is necessary to mine iron ore to build a steel plant, the blacksmiths on the manor outside the city cannot rest, so they can continue to use those pig iron to make parts, the quality of the parts is not up to standard, and it can barely be used at present, and these unqualified steam engines will be eliminated after the appearance of steam engines made of steel.

Time doesn't wait for me, Yun Yi doesn't want to waste time, countless forces gather in the Yun Clan, giving infinite pressure to the little Yun Clan, this feeling is really bad.
