At this moment, Li Yan has already become a celebrity, and he has also become the mayor of Boryeong City, that is, the former prefect. A month ago, Zhang Hongbin re-divided his administrative structure into five major units: village, township, town, county, and province.

Baoning City belongs to Sichuan Province and is also a front-line city that the Qin army has just defeated, so it is necessary for a person who is both civil and military to defend it.

Li Yan's family is knowledgeable and a talent, and it is rare that he also dabbles in the art of war, Yunwen and Yunwu. It may not be possible to be a brave general, but it is just right to be a Confucian general. Originally, if there was a red lady as a partner, the combat effectiveness would increase exponentially, but now the red lady seems to have been dug into a corner by Li Dingguo.

However, Rao is like this, Li Yan still sits firmly in his official position, has the trust of Zhang Hongbin, and silently contributes his own strength to the prosperity of Daqin.

As in history, he is already married, and he and his wife are very affectionate, so I am afraid that I will not take a concubine in this life. After a butterfly effect, this general of the Great Shun Dynasty has become a very pure civil official.

The Red Lady is only afraid that he will be unblessed in this life, and the Red Lady does not know him. Now that he is the first to meet Li Dingguo, the relationship between the two is also out of the warming period, maybe when they will start talking about marriage. As for the question of the red lady's eldest Li Dingguo's three years old, this is not a big deal, the female junior holds the gold brick!

For the red lady, to be honest, Zhang Hongbin, who was originally a bit of a historical figure, really had an idea.

It's like knowing that Yang Ai is Liu Rus, I don't know why the love for her in my heart has increased a lot, and I even have an urge to take the house. Even in the early days of crossing, he also fantasized about Qin Huai Bayan, except for the earliest debut and has died, the others are all little Lori, Liu Ru is the oldest among them, born in 1618 AD, and is now fourteen years old. Gu Hengbo is one year younger than her, and he is only thirteen this year.

Most of the others were born between 1623 and 1624, and are now only eight or nine years old, and it is not to be said whether they have been sold to the Qinglou or not. Maybe because of the butterfly effect caused by their own appearance, how many of them don't have to fall into the fire pit?

Later, there were more women around him, and Zhang Hongbin felt a sense of responsibility. Yourself is not desired. The beast only knows how to vent, and since it wants someone else's body, then it should take on the responsibility of being a man and devote himself to loving them. Now it is a bit reluctant to divide himself into four parts, not to mention that Sun Tingfang is already Liu Ruye's assistant, and he will have to accept the house again in a short time.

Continuing to mess with flowers or something, obviously a bit inappropriate at this stage. A qiē still has to focus on the great cause, so he also learns from Li Shimin, before he made a fortune, he had one by his side, and he began to accept concubines when he became the emperor, and he thought that there were many ministers who said that the number of people in the harem was too small, and it was related to the prosperity of the Tang royal family, and he was asked to expand the situation.

Therefore, the red lady Zhang Hongbin doesn't plan to provoke, and since Li Dingguo likes it, it's not bad to see how he and the red lady are created. Just as Li Dingguo regarded him as his elder brother, Zhang Hongbin also regarded Li Dingguo as his younger brother. This little kid who is only eleven years old this year and is already shouldering the heavy responsibility of the military state, Zhang Hongbin is indeed a little pitiful, and even when there is no one, he sighs how can such a small body withstand such heavy pressure......

Hopefully, he can be happy.

After making up his mind, Zhang Hongbin also silently watched the development of things and blessed Wang Er and Li Dingguo.

At the same time, in the Beijing Palace of the Ming Dynasty, Chongzhen has been depressed again in the past few days.

It was rare to get the most advanced firearms, but I didn't expect that according to Jin Yiwei's report, the drawings of these firearms were drawn and secretly brought to Houjin. Houjin's spies are very hidden, and for the sake of this drawing, they even sacrificed more than a dozen dark lines, thinking that there are so many enemies lurking around him, Chongzhen feels cold behind him when he thinks about it.

At the same time, the theft of firearm drawings made him feel even more depressed. Houjin's combat power is already very terrifying, if he is equipped with powerful firearms, is Daming really still the opponent of the other party? It's just that now, the only way to do this is to make these firearms because they don't have enough technology.

Thinking of this, Chongzhen also hastily ended today's morning dynasty and came to the workshop of the Shenji Camp. Now there are more than 300 outstanding firecracker masters from all over the country here, making every effort to imitate the firecrackers obtained from the Qin army. Chongzhen came over today, mainly to see how it went.

Finally, he was asked by the waiter of the Ministry of Works, but the waiter of the Ministry of Works couldn't tell what kind of process he had reached, so he could only call the chief engineer who was responsible for managing the craftsmen.

"Back to the emperor, at present, we have completed the development of grenades, but we have changed a way of ignition, which is the easiest to imitate, but the gunpowder used by the other party is very strange, we have never heard of it, and there is no way to imitate it, and the result is that the power of grenades or other firearms has decreased, and even dropped by more than fifty percent; We have also completed the imitation of the Wheel Firecracker, after all, this thing has been introduced to Yangyi before, but it has not been taken seriously; It's just that for the infantry firearm, there is no way to imitate it well...... "The chief engineer's surname is Ma, but he is also a real craftsman, and he has devoted himself wholeheartedly to the imitation work during this time, and even has very little time to eat and sleep."

"Is there a way to analyze the composition of gunpowder? In addition, what kind of problem does the fire gun have? Chongzhen's face was not very good-looking.

The firebolt is a real combat weapon, and if this can't be imitated, even if the wheelfirearm and grenade are developed, it won't be of much help to a war. Besides, if the gunpowder is poor, the power of the grenade will be limited, which is also a hard wound.

"The only thing we know is that the other party used cotton, but there is no way to know how to make cotton have such a powerful explosive performance. I checked the information before, and I heard that there is a discipline called chemistry on the Qin side, and I want to have something to do with it. It's just that there aren't enough textbooks, but there's no way to know the mystery.

As for the firecracker, let's not talk about anything else, just the material. The Qin State uses very good steel, and if we want to build this kind of steel, it will take a lot of effort and a lot of scrap. Even with the best technology, the steel created may not be as good as this kind of steel, and it is really a shame that the Qin State is willing to use it to make firearms, otherwise whether it is to create armor or weapons, it is a rare treasure in the world.

If the quality of the steel can't keep up, then the power of the firebolt will decrease.

Not to mention drilling those rifling, the general iron drill will make the inner wall thinner, the original quality is not up to par, and if you have to grind thin, it is not impossible to even explode the chamber with the first shot. Even if one or two shots don't blow up, they won't last long in the end, and the power will decrease. Besides, if you really want to drill such a gun pipe, not to mention other parts, it will take more than six days to do this alone, in other words, if more than 300 people are invested in it now, it will take more than ten days to build 300 guns.

However, if you want to calculate the equipment of gunpowder, the processing of other parts, and even the forging of steel, I am afraid that it would be good to be able to make a hundred guns in more than 30 days. The foreman Ma also told the truth, but he didn't expect Chongzhen to hear this, and his face became worse and worse.

The technology can't keep up, and it can be summed up as a result.

I don't know why, Chongzhen suddenly remembered the Jinyi Wei secret report, Zhang Hongbin's conference about science and technology. In the past, I may have only thought that it was self-deception, or the words of the common people. Now it seems that the accumulation of technology is indeed related to the key issue of a country's strength.

Tong Guò Jinyiwei, he has learned that Zhang Hongbin's side can produce more than 3,000 firecrackers a month, and this speed has increased recently. Come to think of it, this technology for making firecrackers has made a breakthrough in some unknown places. It's just that I just learned from my side that my side can only build more than 100 firecrackers in a month.

Five thousand against a hundred, there is no comparison at all. Not to mention that the other party's steel is better than itself, and the gunpowder is better than itself, so that the power of the firearm is far greater than its own. At that time, even if he imitated it and faced the pseudo-Qin on the battlefield, the result would still be his defeat.

"No matter what you think, be sure to find a way to improve your technology, get along with each other to improve efficiency, come up with ways to reduce losses, and come up with ways to improve quality, and I will reward them with money! If there is a heavy contribution, I don't mind rewarding him with a background! Chongzhen can only give promises.

Given the background, the most is also the same Jinshi background, and if you are lucky, you can be an official.

With this promise alone, the enthusiasm of all the craftsmen was also mobilized, and sure enough, it didn't take long to come up with the method of assembly line, and the efficiency improved a lot. Chongzhen was very happy and rewarded the craftsman who came up with this method with a hundred taels of silver...... According to the rules, there were only thirty taels of silver to the craftsman.

The purchasing power of thirty taels is not low, but such a good method is worth thirty taels of silver, so I am afraid that there will be no rewards for some of them, right?

Chongzhen didn't know that it was precisely because of this kind of reward decided by patting his head, or not knowing the reward of buying horse bones, that the enthusiasm of craftsmen could not be improved, and in the end, except for the method of assembly line, no new things have been discovered.
