With Zhu Cijiao's explanation and tips, the finished bullets and shells were quickly made.

Looking at the yellow-orange bullet in his hand, although the surface was still a little rough because the process could not be reached, it had already given Zhu Ci an extremely excited and familiar feeling.

There are also cannonballs, which are connected to the cartridge, and a fuse made of radium mercury is installed at the tail of the projectile, and at the bottom of the cartridge there is also a primer made of radium mercury! Through this shell, Zhu Ci thought of all kinds of artillery, mountain artillery, mortars, and naval artillery in later generations

With bullets and shells, all that's left is to develop guns and cannons that use them.

According to Zhu Cijiao's estimate, the finished product will be produced within about three months.

Firearms Bureau, Firearms Research and Development Department.

Ji Niansheng took out a musket from a cabinet that was slightly different in appearance from Ying Longjun's current standard flintlock pistol, the difference was in the back part, which was actually a breech gun!

Ji Niansheng is worthy of being a genius in firearms, and the developer of the Daming flintlock pistol has already developed a breech gun that is more advanced than ordinary flintlock pistols!

The breech gun is a one-third faster reload than an ordinary flintlock pistol, which means that if an army is replaced with a breech-loading flintlock pistol, the firepower can be one-third stronger than before, which is equivalent to one-third more troops!

"It's a pity!" Ji Niansheng shook his head, and then said clearly: "No wonder when I dedicated it to the emperor a year ago, although the emperor gave a very heavy reward, he didn't adopt production, and still let Ying Long Army wear an old-style breech flintlock pistol, the appearance of bullets has made the flintlock pistol useless, the emperor probably expected it a long time ago!" ”

Ji Niansheng sighed, admiring Zhu Ci's foresight!

"Although this breech gun has no chance of being born, a more powerful firing gun will also be born in my hands!" Ji Niansheng said with a fighting smile!

Ji Niansheng was full of energy, and after putting the breech flintlock pistol in his hand back in the cabinet, he immediately summoned all the craftsmen in the firearms research and development department to start developing the firing pistol!

Although the firing pistol is more advanced than the breech flintlock pistol, in fact, in terms of technical content, the technical content of the firing pistol is relatively low, and Ji Niansheng is confident that the finished product will be made in less than three months!

The firing gun is being developed, the firing gun is also being developed, and the entire firearms bureau is in full swing!

Seven days have passed, and Zhu Ci took time to see Chen Xiuxiu twice halfway, and on the day she recovered from her injuries, she was ordered to be appointed as a counselor of the Firearms Bureau and the Academy of Science and Technology, and she can enter and exit at will and participate in all the projects of the Firearms Bureau and the Academy of Science and Technology.

For the first time, another kind of female official appeared in the Ming Dynasty besides the female general and the female official of the inner court!

As expected, this undoubtedly attracted the opposition of some officials who had nothing to do, on the grounds that there were no female court officials other than female generals in the Ming Dynasty!

There are not many officials who really oppose it, most of them are still very knowledgeable, and Zhu Ci didn't even owe a glance at the dozen or so books of recitals against this matter that were sent to him!

"Grandpa, look, I'm also an official, it's the sixth grade, the emperor is so good to me!" Chen Xiuxiu took the canonized holy decree and came to Chen Xin in a hurry.

Chen Xin's face did not feel happy at all, but his face was bitter.

In fact, Chen Xin tentatively stated in front of Zhu Ci that he didn't want his granddaughter to come to the Firearms Bureau again, and hoped that his granddaughter would wait for her family at home, but Zhu Ci didn't hear it and ignored it at all!

The reason is too simple, there is only one Chen Xiuxiu among the people in Daming, her mind about science and technology is inseparable from the current development of Daming, this national treasure-like talent, Zhu Cicheng can let her do nothing at home, just kidding! So Chen Xin's expectations were disappointed!

"Xiuxiu, in fact, the emperor, hey! Forget it, put away the decree and do not break it, or the sin will not be small! Chen Xin said with a sigh.

In fact, he wanted to say that the emperor didn't care about her at all because he gave her this holy decree, but just took a fancy to her talent! However, such words were full of disrespect to the emperor, but Chen Xin couldn't say what he said, and finally turned into a helpless sigh!

After all, this holy decree has been issued, even if he doesn't want to, what else can he do?

"Well, Xiuxiu knows!" Chen Xiuxiu nodded, and a flash of brilliance suddenly flashed in her smart eyes, this was the first thing the emperor gave her, of course she had to take good care of it!

As Chen Xiuxiu's grandfather, Chen Xin saw Chen Xiuxiu's thoughts at a glance, and immediately sighed again, it was time to interrupt the thought in Xiuxiu's heart that should not have appeared in the first place.

"Xiuxiu, you come with grandpa." After a pause, Chen Xin said suddenly.

"It's Grandpa." Chen Xiuxiu didn't think much about it.

Chen Xin pulled Chen Xiuxiu to a place with few people, and it seemed that there was something unusual to say.

Chen Xiuxiu had some doubts at this time and asked, "What's the matter, grandpa, is there something wrong?" ”

"There's something!" The expression on Chen Xin's face became solemn and continued: "Xiuxiu, you will be eighteen years old in two months, grandpa has taken you for all these years, it's time to find you a mother-in-law!" ”

"Huh?" Chen Xiuxiu was shocked, her grandfather actually told her this kind of thing, but she didn't want to.

"Grandpa, but me"

"You're going to turn eighteen years old, you're an old girl, no one will want it in two years, grandpa can't be so selfish!" Chen Xin seemed to know what Chen Xiuxiu was going to say, and before she could finish speaking, he interrupted Chen Xiuxiu's words.

In Daming, a girl's family can marry at the age of fifteen, and when she reaches the age of eighteen, she is a big girl, and if she can reach the age of twenty, she either has a hidden disease and no one wants it, and there are very few who have not found a husband.

"Xiuxiu, the reason why grandpa told you in advance is to let you have a preparation in advance, grandpa is already looking for it!" Chen Xin said.

Indeed, Chen Xin has been looking for a long time, and it is almost done, although he is reluctant to marry his granddaughter, but he can't watch his granddaughter jump into the fire pit step by step, the palace is not a good place, the most important thing is that he has already seen that the emperor has no idea about Xiuxiu at all, if things are allowed to develop, only Xiuxiu will be hurt.

After Chen Xin finished speaking, without waiting for Chen Xiuxiu to reply, he turned around and left!

"Grandpa." Chen Xiuxiu shouted, but Chen Xin didn't look back.

I don't know why, Chen Xiuxiu's heart suddenly clenched tightly at this time, there was an uncomfortable feeling of suffocation, and she wanted to cry!
