The six-shot musket is actually a rifle version of the revolver, but the weight has been increased by more than 50%. The steel of this year is not passable, and the barrel is still very thick, which makes the weight of the barrel naturally not less. However, this design also has the advantage of being able to replace the barrel at any time, and it can be replaced before the barrel overheats.

In this way, the service life of the firecracker and the safety of the soldiers are fully guaranteed.

In terms of artillery, the old wood also gave Zhang Hongbin a surprise, that is, the latest heavy mortar has been successfully cast. The newly finished mortar weighs seventy-five kilograms, and two people can still carry it, and up to three people can easily carry it away. It was a little less powerful than Napoleon, but it was enough for storms in the mountains and forests. Needless to say, this kind of artillery is naturally used to fight mountain warfare, and the object is also very clear, naturally it is the Sichuan region.

Yes, Zhang Hongbin's next target is Sichuan.

This was already predetermined early on, because he needed to conquer Sichuan, and then conquer Yunnan and Southeast Asia, and even occupy the southern part of Guangxi, and finally obtain an outlet to the sea, and use the advantages of the Beibu Gulf to develop the maritime industry. Overseas colonization or something, maybe you don't have to think about it, but he also wants a piece of the pie in sea trade.

Traveled to an age of discovery, even if Britain has risen to the era, if you don't join it, wouldn't you regret it for a lifetime?

"By the way, wood, what's the name of this new type of firecracker and artillery?" Zhang Hongbin asked curiously.

"This kind of artillery and fire gun is called the first year of King Qin of the Mu clan, and this year is the first year of your reign King Qin, so it is named after it." Old Wood smiled and said.

"I see, but I, the King of Qin, don't have any era names or anything like that. But thanks to you, I seem to have really forgotten about the revision of the calendar. Now that a regime different from the Ming Dynasty has been established, we can't do without our own calendar! Zhang Hongbin pondered for a while and said.

"To put it simply, if a proper calendar is established at the beginning, how can there be such a practical name as 'Mu Chongzhen three-year style'? You know, now some people seem to be muttering that I am in Daqin, and my heart is bright. It's just a joke, if we go back to Daming, our family will have to starve to death, and the fool will return to a family even if he is no longer so disdainful, but that kind of discrimination and contempt, and even the feeling of not being respected at all, the old man doesn't want to experience it anymore. The old wood also said indignantly.

"Hehe, I'm still very clear about your loyalty to wood. The original fire bolt was still the same name, after all, we didn't have our own calendar at that time. Besides, even if I overthrow the Ming Dynasty one day, I am still afraid that people will remember it and overthrow myself? I have always believed that the reason for the rebellion is simply that the life of the people can no longer pass, or that they are fooled by ignorance.

Then, if I give the people enough food and clothing, so that they know how to distinguish between right and wrong, then who else in this world can shake my rule? Zhang Hongbin said with great confidence.

Lao Mu didn't know how to govern, but he also understood that the establishment of a new dynasty would inevitably negate and stifle the glory and existence of the previous dynasty. However, Zhang Hongbin didn't plan to do that. In this way, his reign will either be smooth sailing, or it will be full of thorns.

Then the old wood smiled and said secretly: What's wrong with me, when will it be my turn to think about this kind of thing?

Shaking his head, he said goodbye to Zhang Hongbin and returned to his job, and devoted himself to the study of firearms. Nowadays, a top craftsman like him is basically out of the production process, and all he needs to do is teach and study.

"Old man Xu, are you still revising Confucian classics?" Zhang Hongbin appeared in Xu Guangqi's study more than ten minutes later.

This old man is still very healthy this year, after all, this is his father-in-law's house, and Zhang Hongbin has not been disadvantaged here. Even if this guy has betrayed himself, the basic usage and medical security are still carried out according to the highest standards.

"Boy, how are you in the mood to be a guest in the house of a sinner like me?" As for why Zhang Hongbin could directly break into Xu's house, Xu Guangqi was not surprised.

First, he is the king of Qin, where to go, who dares to stop him? Second, he is also the uncle here, half of Xu Shou's son, and half of his grandson. Therefore, it is not difficult for him to enter the Xu Mansion, at most it is rude; Third, Zhang Hongbin's strength and speed are so great now, if he wants to break in, no one can really stop him, maybe the internal guards in disguise can, but they naturally won't move King Qin.

"It's nothing, there's something to talk to you about, to be precise, there's something I need your help with. These are the texts that you have revised...... Forget it, I don't understand it. Zhang Hongbin casually picked up a book and looked at it, then put it down.

This girl knows that she has promoted punctuation and pinyin, but the book is still in accordance with the original writing mode, but there is no half punctuation. Such a book is too difficult for Zhang Hongbin to read.

"Your original is the material I used as a reference, and since it is a material, it naturally does not add any punctuation." Xu Guangqi smiled.

Well, Zhang Hongbin can only reflect on who let himself put an oolong before.

"Tell me, what does it take for me to do this old bone. If you don't talk about it faster, God knows how long my bones will last! Xu Guangqi saw that Zhang Hongbin was embarrassed, and his heart was a lot less depressed, and he didn't bother to talk nonsense with him, so he directly pointed out the point.

"Calendar, I heard that Duke Xu plans to revise the new calendar for Chongzhen. As for me, now that a new regime has been formed, it is natural that a new calendar needs to be revised. Xu Gong seems to be a little too idle lately, I don't know if I can help? Zhang Hongbin also directly explained his intentions.

Xu Guangqi has experienced the compilation of a calendar or something, so he should be the most experienced.

"I'm sorry, I don't help any forces other than the Ming Dynasty compile the calendar." Xu Guangqi directly refused.

Well, even if half of his foot has already entered the coffin, there is still no way to cool his blazing patriotism.

"Listen to me, I'm not going to write something like the Qin era, I need to revise the Chinese calendar from the year when the first emperor Yingzheng ascended the throne. Since that time, China has entered the feudal era, and it can be regarded as half a foot into the real civilization era. I will not evaluate the first emperor before and after his death, but the value of his ascension to the throne as the first emperor cannot be erased.

I heard that the West uses the year of the birth of Jesus, that is, the Western god you also believe in, the so-called beginning year of the Gregorian calendar. Then we also use the year of the first emperor's accession to the throne as the beginning year of the Gregorian calendar of our Chinese nation! Personally, I think that this calculation method is more suitable for our Chinese nation than the new calendar designed by your old man in the Ming Dynasty. And after the promulgation of this new calendar, I will also send a copy to Daming, I believe that Xu Lao, you will not refuse now, right? Zhang Hongbin guided him step by step, and he could also see that Xu Guangqi was becoming more and more interested.

"That'...... All right! Xu Guangqi really gave in, after all, he found that this calculation method was much better than the original one he had designed, at least more in line with the Chinese nation. Since Da Ming can also get a copy, then naturally he can help, it's a big deal to learn ostriches, saying that Da Ming originally improved the calendar, and then Zhang Hongbin, the king of Qin, used it. En, he is a loyal minister of the Ming Dynasty, he is alive and dead!

Now that the main supporter has been chosen, it is much easier for the rest to choose a few assistants.

It was only a month before and after, and when the time entered the autumn harvest, Xu Guangqi revised the calendar of the First Emperor on the basis of the original experience.

According to this calendar, the year is 1631 A.D., which is also the year 1851 of the First Emperor's calendar. The calendar is calculated from the year when Qin Wang Shi Huang established the imperial system, that is, in 220 BC, to 1851.

Since then, the world has entered a new era.
