Cao Guogong's Mansion, at this time in the backyard where the subordinates were, the Li family's chief butler said loudly: "Of course, our master can't bear to do this, but how can we not think about the main family?" ”

"There is more blood transfusion, on the battlefield is equivalent to an extra life after trauma, our family is a general, maybe one day on the battlefield again, blood transfusion is essential. Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 ｉｎｆｏ”

"The eldest young master was also worried about the master, so he secretly promised the eldest master: 'Whoever is willing to receive blood will be rewarded with fifty yuan of money; Therefore, if he died, his old parents, wife and children were raised in the Cao Guogong Mansion for a lifetime, and the house arranged errands when the son grew up; If he falls ill, he will be raised in the house for a lifetime, and the house will also arrange errands when his son grows up. ’”

Although the servants below did not talk loudly, they all looked at the big butler with inexplicable expressions: Do you think we don't know who the eldest master is? The eldest young master concealed that the eldest master had such a promise in private, how could it be!

However, even if it is guessed that Li Jinglong is hypocritically instigating this matter behind his back, it does not mean that the servants will definitely not be willing to become Li Jinglong's mobile blood bank.

Many people are weighing, especially those who are not in good health because of various acquired reasons. The Li family who followed Li Wenzhong and Li Jinglong's father and son to the battlefield and was injured must have to be raised, but because of other reasons, they have problems with their legs and feet, and they are all thinking about it.

After a while, a man who could not do heavy work because his right foot was injured and could only stay in the mansion by virtue of the two generations of father and son serving in the Cao Guo Mansion stood up and said, "I am willing to have a blood transfusion." ”

Later, some people came forward one after another, but the number was not large, after all, there were not many people who were disabled the day after tomorrow, and the largest proportion of battlefield disabled people basically did not come forward.

The chief housekeeper of the Li family said kind words to comfort these people who came forward, and Li Jinglong's eldest son Li Tangbang also came out to appease them.

However, the chief housekeeper of the Li family still thought in his heart: "There are still too few people, and most of them still need to report to the eldest master to find someone in the army." There are many disabled people in the army, and there are not many pensions from the imperial court; In addition, people with disabilities are not only unable to go to the battlefield to fight, but most of them are unable to do the work at home, and if there is such a thing to reduce the burden on the family, most of them are willing. ’

=======================================================

From the time Zhang Wen asked about Yunxi's blood transfusion, so that the blood transfusion was feasible all over the capital, all the nobles were doing similar things to Li Jinglong, but most people would not be as hypocritical as Li Jinglong and still hide it in the face of their own servants.

For example, Chang Sen is very direct to find among the servants at home, and he doesn't need the housekeeper to carry the black pot.

The disabled soldiers of the 48th Guard in the capital soon discovered that they had a way to come in handy again, and each family rewarded this kind of person very generously, which made the able-bodied people excited. If there is not a small possibility of dying directly, it is estimated that there will be many able-bodied people who are willing.

Later, a physician asked, 'Isn't this similar to a drop of blood!' Then it suddenly became clear to parents and children that blood transfusions could be done without problems, so most families switched to using the incompatible method of blood drops to determine whether the blood type was the same.

This led to an important thing, that is, people found that it was unreliable to recognize relatives by dropping blood, because there were so many people who could not be related by blood together, which caused a great earthquake in the Chinese medical community, and also caused great surprise and shock to the people of the Ming Dynasty.

In the following years, the earthquake spread to most parts of the country, but it took a long time for the civil society to spread throughout the country.

Yun Xi actually knows that most of the compatible blood is the same type of blood, but Yun Xi remembers that he saw an article in his previous life, saying that even if the same type of blood can be fused together, it will be life-threatening due to lymphocyte resistance and other problems, and it can only be safest after scientific testing.

Yunxi now has no means of scientific testing, only the most earthy method, directly input into the body fusion method to detect. This is also the reason why Yun Xi did not propose a method of incompatibility with blood, anyway, he is the emperor, and there is no shortage of people who can use it.

(The above content about the possibility that compatible blood transfusions of the same type may also be dangerous in the body are found on the Internet)

A few days later, the first blast furnace of the Ming Dynasty was erected in Meishan. Yun Xi also personally went to the scene and praised the officials and eunuchs in charge of the Ministry of Works, the internal official supervisor, and the leading craftsmen. Although the iron production of this blast furnace is not high, and there are problems from time to time, Yunxi still praises them vigorously.

Then Yun Xi told the officials: "Pay more attention to the opinions of craftsmen." ”

"Most of these craftsmen are not good at managing things, but they are very clear about whether there is a problem with the blast furnace."

"Although I want you to produce more iron, I can't cause a catastrophe in order to produce more iron at the expense of possible problems! If the blast furnace is broken and the craftsmen are killed or injured, I will not follow. ”

In addition to the blast furnace, the firearms have also been improved in accordance with Yunxi's previous instructions.

When the craftsmen found out that the gunpowder ratio that Yun Xi said was indeed more powerful, and the granular gunpowder was indeed easy to load, which also made the gunpowder more powerful, they were shocked by Yun Xi, although they did not know Yun Xi's true identity.

With the implementation of new gunpowder, as well as the unification of artillery and musket specifications, the use of fixed gunpowder and the unification of shells and bullet specifications, Daming's firearms are more powerful, and the aiming system can also be put on the agenda.

Yoon-hee also instructed them to study how to reduce the weight of the artillery. The 75 mortars in his impression were very small, and one person could carry them, but they could also be shot out for four or five miles; At this time, a few thousand catties of artillery could be fired out for four or five miles, and the power was not as powerful as that of a 75 mortar.

Although the technology iteration is very fast, and the technical level after five hundred years is not the same as at this time, one in the sky and one in the ground, Yun Xi still feels that it needs to be improved, at least the cannon should be lighter.

After that, Yun Xi was very familiar with blast furnace ironmaking, and visited the iron factory many times to guide the construction of blast furnaces.

Although the civil officials were a little slanderous, they felt that the improvement of the blast furnace should be the business of the craftsmen, and as the emperor, it was good to delegate the matter to the officials, and there was no need to personally guide it. But after all, iron is very important, and now it is the beginning of the Ming Dynasty, except for a few imperial history books on this matter, the ministers who do practical things are silent about it. This made Yunxi even more determined to "downsize" the imperial history.

The construction of the track from Pukou to Chuzhou also began. Bai Xiguang, the eunuch of the Imperial Horse Prison, completely threw himself on the construction site, and in order to keep his position as a eunuch who was in danger and could be replaced at any time, he also fought hard.

As soon as he began to fight, all the craftsmen could only follow the effort, resulting in the rapid construction of the railroad track.

Yunxi also paid attention to the development of the shipbuilding industry in Daming. However, Yun Xi is ignorant of shipbuilding, seeing that the Ming Dynasty still has shipping, a large amount of grain shipping in Liaodong every year, although the official shipyard cost is higher, but the technology is still available, after deciding not to point fingers at the shipbuilding industry.

In the blink of an eye, it's November.
