Now the quality of steel and the manufacture of muskets are completely up to standard, but the craftsmen are not familiar with the process, Bai Ziyun decided to cast the artillery first, so that the craftsmen can understand the firearms first.

The military factory was built near the steel mill, and when Bai Ziyun came to the military factory, Zhuang Zhou, as the supervisor, organized a meeting of the craftsmen. Seeing Bai Ziyun, they all saluted.

"Now have you come up with a plan for casting cannons?" Bai Ziyun asked.

Zhuang Zhou said: "Although the master provided a complete set of casting process, the current mechanical technology is not perfect, and we are novices, and we have never had experience in casting cannons, so after discussion, we decided to use the iron mold casting method first." ”

Bai Ziyun nodded, this is what he expected, the iron mold casting method, it is not difficult to say, now the Han Dynasty has an iron model mold for casting agricultural tools, if you understand the structural principle of artillery, many craftsmen in the Han Dynasty can use this method to manufacture. Therefore, the "iron mold casting method" invented by Gong Zhenlin during the war is not much unusual, what is the use of inventing it decades earlier than the West, and Western countries have been using more advanced sand casting methods in that era.

"What about the sand casting method?"

"Master, the sand casting method requires a lathe to drill, ream, boring and other processes, and we do not have such mechanical technology yet. When will the steam engine be built? ”

"Although the technical difficulty of the steam engine is not very high, the precision required is relatively high, and now our machine tools are not up to this standard, let's talk about it after a while. You first use the iron mold casting method to make a few cannons, and after the test is successful, you will hand them over to the artillerymen. ”

"No!"

The technical difficulty of the iron mold casting artillery method is not high, and I believe that under the leadership of Zhuang Zhou, it should be able to make artillery in a short time. Bai Ziyun didn't take this matter to heart, and after returning to Baijiazhuang, he called the four beautiful concubines in spring, summer, autumn and winter.

Bai Ziyun looked at the four delicate girls and said, "The four of you have all cultivated the inner breath, right?" ”

"Yes, master." The four concubines said ashamedly, their qualifications are the worst qualifications, and they have been practicing qi for four or five months, and they have only recently sensed internal qi.

"With your qualifications, even the improvement of your qualifications for cultivating muscles and refining bones is very slow, so this seat has specially improved a skill for you to improve your qualifications, but this exercise can only be practiced by men and women, that is, a double cultivation method." Bai Ziyun looked at the four girls with a smile.

The fourth girl has been following Bai Ziyun for so long, so she naturally knows the meaning of double cultivation, and her face suddenly turned red, four women, you look at me, I look at you, and she smiled.

"We will do whatever the master tells us to do." Chunyu smiled deliciously.

"Master, do you need the four of us to serve the master and cultivate together?" Xia Xuemei looked forward to it and said with some embarrassment.

"No need, I only find one person every time I cultivate." Bai Ziyun shook his head and said, double cultivation has to do that, but the practice is the focus, and it can't be disturbed.

"Oh." The four girls breathed a sigh of relief, although Bai Ziyun often let the four girls serve together, and the four girls were used to it, but seeing other women in love with their masters, they would always feel a little uncomfortable.

Bai Ziyun continued: "This exercise is called "Shenlong Su Women's Gong", which is specially for women to practice, and unlike other exercises, the reason why it can improve women's qualifications is because when they are in love with men, they can guide the yin and yang qi of both men and women to enter the woman's body to wash the meridians and cut the marrow, so as to improve the woman's martial arts training qualifications. But there is a problem with this exercise, that is, after intercourse with a man, although the qualification is improved, the internal force in the body will also disappear eighty percent, part of the washing and cutting of the marrow is consumed, and the other part enters the man's body. ”

"Shenlong Su Nu Gong" is from Stephen Chow's version of "The Legend of Deer and Ding", the movie says that to practice this exercise, you must be a virgin, and you must maintain a virgin body, otherwise you will lose your eight success power when you comature with a man, then Wei Xiaobao took a big advantage and got eighty percent of the internal strength of the leader of the Shenlong Sect, and became a peerless master.

The Shenlong Su Nu Gong in the system is also such a characteristic, but there is a big difference, that is, it does not have to be a virgin to practice, as long as it is a young woman, you can practice, think about the so-called virgin is just an extra layer of membrane, how much effect can it have on practice, those so-called ** will lose Yuan Yin and Yuan Yang, it is just the speculation of the ancients, and it is not scientific.

"Huh?" The four girls were quite surprised when they heard that this exercise was so wonderful.

Chunyu said with a smile: "This exercise is interesting, it seems to have been specially created to improve men's internal strength. ”

Bai Ziyun shook his head and said: "At first, this skill seemed to be a practice that harmed oneself and benefited others, but in fact, it is not, Shenlong Su Nu Gong is a cultivation of the original solid yuan, first cultivate the inner and then the outer exercises, Shenlong Su Nu Gong has a total of nine layers, the first three layers are the acquired realm, which is the period of improving qualifications, the so-called sharpening knives do not mistakenly chop wood, their own qualifications have improved, and they can go further in the martial arts in the future, and they can practice high qualifications and practice fast, such as the master I, I have entered the innate period after only a few months of cultivation, and I have several disciples with the highest martial arts qualifications, If you want to enter the congenital stage, it will take ten years to say the least, which is the benefit of high qualifications. ”

The simple-minded four girls were fooled by Bai Ziyun, their eyes became brighter and brighter, and they only felt that the master was really good to herself, such a profound exercise for us to cultivate, and we must serve the master wholeheartedly in the future.

In fact, the Shenlong Su Nu Gong is not as good as Bai Ziyun said, although this exercise has many advantages, but it is very cheating in the early stage. There are nine layers of Shenlong Su Nu Gong, this exercise is very strange, the first three layers, the internal qi will become deeper and deeper, but most of them cannot be used, the power is very small, and after breaking through the fourth layer, the power has increased greatly, and he has become a peerless master.

After a woman cultivates this exercise, once she interacts with a man, the eight achievements of her own internal force will be lost, and part of it will enter the man's body, and the other part will be the marrow of her own I Ching, so as to improve the body's martial arts qualifications, and the speed will be accelerated in the next cultivation. From this point of view, this exercise is very subtle, and it can be said to benefit others and oneself.

"This exercise has advantages and disadvantages, if any of you are unwilling to cultivate, I will not force it." Bai Ziyun said gently.

"This is a generous gift from the master, and the slave is willing to cultivate!" Dongyue, who has always been silent, was the first to say.

Then the other women also expressed their willingness to cultivate, and they were very happy. They don't care about their internal strength, as long as they can get the favor of their master, they are satisfied.

"Hmm." Bai Ziyun nodded in satisfaction.

It was also a helpless move for him to come up with this dual cultivation technique, and his progress in cultivating internal strength has been getting slower and slower recently, and he is afraid that it will be far away to break through to the realm of grandmasters. After some final calculations, he came up with the reason that it was because the aura in this world was not enough, and the concentration of aura in the air was not enough to support him to enter the next martial arts realm.

He doesn't know the spirit gathering array in the Xianxia world, so he can only start from the aspect of absorbing internal force, and the most famous way to absorb other people's internal force is the Northern Shengong, but the sequelae of the Northern Shengong are quite large, otherwise the Xiaoyao faction would have been full of masters. The same is true for others such as the Wedding Dress Divine Skill (providing internal force to others) and Mingyu Gong (which can absorb internal force), all of which have great shortcomings in themselves, so after making a choice, it is this seemingly very lewd + double cultivation method that is most suitable for themselves.

Using women as a furnace to improve themselves, four beautiful concubines are obviously not enough, Bai Ziyun considered whether to make a draft or something.
