Compared with Lu Changxin, Wu Zhennan's martial arts are not worth mentioning, but his equestrian skills are good, he is also kind, he can speak better than Liao Xingtian, he is more likable, and when he is not killing people or performing tasks, he belongs to the more harmless type of livestock, as Old Man Xu said, Liao Xingtian and Wu Zhennan have been old partners with him for many years, and there has not been a single mistake during this period!

This record is really terrible, and they don't even need to be dotted, but they will also send more "filial piety" items to them by passing bandits and robbers, and the latter is absolutely not greedy, and all of them are handed over to the organization......

Presumably, Old Man Xu called the two of them to ensure the safety of the mission and speed up the journey to improve efficiency. Pen ~ fun ~ pavilion www.biquge.info

Su Zedong instructed the old man Xu to pay attention to safety, don't be reckless when you encounter problems, the goods don't matter, the person is fine, the latter didn't say much, just smiled and nodded, and after he finished speaking, the old man Xu said: "Please rest assured, the old man has lived for most of his life, and he doesn't dare to say anything else, but only this business can still come out and say." ”

Su Zedong nodded with a smile, and then respectfully sent Old Man Xu back to the room with everyone and asked him to make some preparations.

"This old man Xu, do you know kung fu? This is a bumpy road from Gaoyou to Dadu."

Xiao Qi'er had just joined Dongzhen Company, but she had never seen Old Man Xu before, so she asked.

Old man Xu is very kind to people on weekdays, looking at her as a girl, but she is very dexterous, although she loves her, but she has no time to communicate with her, but when she says goodbye to everyone, she looks at it a few more times, smiles and nods at it, which arouses the doubts in the little girl's heart.

"Oh! I just remembered that the last time I went from Dadu to Gaoyou, you weren't on the same route as us, so naturally you didn't know Old Man Xu! Hahaha, don't worry, Old Man Xu is a good man! I'll have time for him to teach you in the future, but for now, you'd better report to me and let you send someone to monitor this Feng's business, how about that person? ”

After everyone sent Mr. Xu back to the house price, Su Zhidong let everyone disperse, leaving Liu Zhenming, Xiao Qi'er and Song Benwen, and then reported to him.

For the three of them, Su Zedong trusts them unconditionally, although they are not the elders of Juyitang, and their seniority is much lower than that of Old Man Xu, but they are the elders of Dongzhen Company, that is, the initiators of the new forces of this era like themselves.

Originally, he wanted to call Su two or three, but he said that he wanted to continue the research and development of weapons, although the project of the three-eyed firearm was delayed due to some restrictions, but he thought that there was always another way to solve it, and he also found that so many weapons in the past dynasties are all interconnected, since there are commonalities, you can find the law, you can develop other new weapons do not understand.

Su Liangsan's enthusiasm for research is beyond Liu Zhenming's reach, he boasted to Su Zedong at the wine table how he studied in depth, how many nights he stayed up, half of that was made up, according to the memory of later generations, as a science student, it is not difficult to design the design of blast furnace ironmaking, but it is a little complicated to make it by hand.

After all, the future generations of high-achieving students pay more attention to theoretical knowledge, unlike the training of practice in foreign countries, engineers can not only design but also welding, grinding and other workers' work, if the workers do not have a skill, or more focused on investment, they will be eliminated by the times at any time, so their blue-collar workers are not only of high quality, but also have the thinking and literacy of engineers.

Since this is a common phenomenon in China, of course Liu Zhenming will not force himself, call a few blacksmiths, write according to the drawings, and make the details described by himself, and then there is a place that needs special processing, and then let people do it slowly, then he is unwilling to stay on the construction site for a while, and he will not stay up late in his own studio, and he will sleep when he is tired.

And Su Liangsan is different, after Liu Zhenming's words and deeds, he calculates a data three times in different methods every time he calculates, and if there is a decimal point, it will be calculated two more times, and if the result is the same, the fifth place after the decimal point will be taken......

Moreover, he has a super learning ability, and he can master the physics of junior high school and high school taught by Liu Zhenming within ten days, which includes the law of conservation of mass, electricity and other formulas and theorems, and his hands-on ability is not bad, he can simulate the circuit diagram, Liu Zhenming has already felt pity for this person's talent, he was really born in the wrong era!

If he had lived in the Hereafter, he would have gone to the Massachusetts Institute of Technology in the United States!

But now that it is in ancient times, everything in later generations can be rewritten, maybe the Nobel Prize will become the Su's Science Prize, everything is unknown!

Whenever he thinks of this, Liu Zhenming is always excited to devote himself to the training of Su Liangsan, his next plan is to prepare the physics course of the university, although he graduated for ten years, but physics is his major in college, even if he can not fully understand the content of the textbook, but he will always read it again...... If you don't read it once, you really don't want to pass the end of the semester!

But Liu Zhenming belongs to the heart but not enough, after all, they are all people who have graduated for ten years, and they have been sharpened by the society's smoking, drinking, games, entertainment venues, etc., so they have no ability to do anything, so when they edit materials and teach carefully, they will always doze off.

If the teacher is not strong, he may not be able to teach the students well, geniuses do not need teachers, and geniuses do not need books! Su Liangsan just took a general look at the tutorial written by Liu Zhenming, and he would go to the factory to observe, personally experiment, and then record it to form a research report similar to that of later generations.

Su Zedong was very happy when he knew this, and asked Su Ersan if he had any other needs?

He didn't have much need for material things, so his only request was to reduce Liu Zhenming's time for eating, drinking and having fun, and teach him more things, which Su Zedong allowed;

Liu Zhenming began to be afraid, not afraid that his time for eating, drinking and having fun would be reduced, if he taught this apprentice, he was really not afraid of begging for food in troubled times, learning mathematics, physics and chemistry, and not being afraid to go all over the world! And what Liu Zhenming is afraid of in his heart is what if the second son of the Su family doesn't like women and is impressed by his erudition?

After staying with him for a long time, my interests tend to be distorted, what should I do?

Liu Zhenming once politely raised this issue to Su Zedong, and the latter also felt that such a thing was not impossible, and it had often happened since ancient times, so it was specially arranged that the person who brought them food every day must be a young woman with good facial features and a good figure, so as to not only maintain the work of the two people, but also maintain the purity of the relationship between the two men.

When the four of them returned to the conference hall again, as soon as they sat down, Su Zedong asked, "Deputy Hall Master Liu, let's talk about it first, what is the problem with the development of this three-eyed firebolt?" ”

Liu Zhenming pretended to learn the way when the leader spoke, paused first, and then cleared his throat before saying, "This ..... The primitive three-eyed firebolt is simply equipped, it is generally equipped in the hands of cavalry, it needs to be ignited with fire, and then through the principle of explosives to generate power, to hit the enemy, its power is not for the time being, it can be seriously injured if it is not killed, but this crosshairs ......"

"It's just good to use it for cavalry, but it's not good for infantry, just the range is a big criticism, plus it's more restricted by the weather, so in addition to being deployed in high-level cavalry, it can't be placed on cavalry or other arms."

After Liu Zhenming finished speaking, the first big one was not Su Zedong, but Song Jiwen and Xiao Qi'er, they first didn't know anything about firearms, and then they didn't understand a lot of the words Liu Zhenming said, so every time they heard the two talking, they would choose to ignore it.

After Su Zedong said "En", he said, "So you want to make a fuss about the crosshairs of the Three-Eyed Fire Gun and the direction of the firing range?" ”

"Of course, if you add more pipes to the three-eyed firebolt as you did before, and become four-eyed, five-eyed...ten-eyed? In the end, it only increased its power, but did not broaden its scope and flexibility. ”

"Well, what is your plan?"

"Improve the material."

When these four words were spoken, Liu Zhenming's mood was apprehensive.

Then Liu Zhenming explained to Su Zedong: Because the selection of materials took a lot of effort from himself and Su, but after designing several tests according to certain standards, the relevant data were not up to standard, and the degree of adaptation was also very poor.

After all, in addition to the traditional iron and copper, aluminum and steel are rarely used, so after several attempts to refine pig iron into mature iron, the effect is not good, and the method of using blast furnace ironmaking, in terms of current technology and cost, can not afford to consume time, and secondly, materials cannot be consumed, unless there is no trading.

Subsequently, the method of frying steel was used to heat the pig iron into semi-liquid and liquid form, and then iron ore powder was added, and at the same time, a part of the carbon in the pig iron was removed by using the iron ore powder and the oxygen in the air, so that the carbon content in the pig iron was reduced, the slag was removed, and the steel was directly obtained, but the impurities produced by this method were more, and the effect was not very satisfactory.

In addition to the steel filling method, Liu Zhenming also consulted the masters of the local blacksmith shop and blacksmith shop, and tried the steel frying method, but the finished product was still poor.

The specific reaction of the poor effect: the weight is still too heavy, and after the shot, the recoil is too great, and Liu Zhenming's goal is to be able to fire ten small shells at a time, so there are still relatively high requirements for weight.

In addition, in order to ensure that it does not "explode" and increase its range, I have tried all the gunpowder that can be found in this era.
