Fifty meters is a very short distance, and if the enemy is on horseback, one charge time can rush to the front.

However, for the shooter, a distance of 50 meters can be used to fire two shots, and a fast speed may be able to fire three shots.

In terms of three-stage shooting tactics, six shots can be released at a distance of fifty meters, and Su Ziheng believes that in this era when armor protection is not very good, there should be no one who can rush in front of the soldiers with the damage of six bullets.

Su Ziheng said with joy on his face: "It should be enough, and when the time comes, let Ou Yajiu start to build a large number of guns, but Mengzi, you leave a gun first, test how long it is, don't go to the battlefield and find that the gun didn't shoot a few bullets, and there was a matter of exploding." ”

Shi Meng responded: "No! ”

The successful production of the flintlock pistol gave Su Ziheng great confidence, and he believed that when the time came, he would train a musketeer of thousands of people, not to mention sweeping the four countries, and it should be more than enough to protect Donghai County.

After the construction of the city wall defense facilities, it is only necessary to close the door and develop the economy.

"But before the flintlock pistol is mass-produced, shouldn't I experiment with the standard amount of ammunition first? Then make a paper shell bullet to ensure that every ammunition load is the most reasonable. Lest they go to the battlefield, the musketeers are too nervous, their hands are shaking badly, and they are loaded with more or less ammunition. ”

"If there is less gunpowder, it will not be powerful, and if there is more, it will explode. If you pack it in a paper bag, bite open the paper bag with your teeth and pour all the ammunition into the chamber of the gun. And there is another advantage of using paper bags to wrap individually is that it is moisture-proof. It's just that in this way, you have to get out the papermaking technique, and it just so happens that after the opening of Bailu Academy, there are many places to use paper. ”

The more I think about it, the more big Su Ziheng is, Donghai County has no foundation at all, everything has to be developed from scratch, and there are too many places to worry about.

When I returned to my residence, it was already dark, and it was inconvenient to go to other places at this time. Su Ziheng decided to turn around where he lived, first copied out the health manual promised to Zhong Qinghan, and then listed the next plan in a sequence, so that he could know what the next key work would be, so as not to miss important things because he was too busy to get dizzy.

Taking advantage of no one's attention, Su Ziheng entered the base space, looking at the encyclopedia, a wry smile appeared on his face. The content of these books is very good, the key is that they are printed in simplified Chinese, and he can't take them out directly, and in order to prevent the books from being damaged, he can't take them out.

Su Ziheng found a book called "The Barefoot Doctor's Handbook", which was compiled not long after the founding of the People's Republic of China to popularize health knowledge and simple medical knowledge, which is very suitable for people who have no basic knowledge to learn.

Just when he was a little big looking at when such a thick manual should be copied, he suddenly remembered Cai'er in the Shenlong Temple, and the people of the Zhang family living in the space, many of them should be literate, and they could let Cai'er organize them to copy the books together and transcribe the information they needed.

Anyway, they can only survive in space, and they don't have to worry about leaking the contents of the transcript. What's more, as long as you control it well, let the content they transcribe out of order, and you don't have to worry about what they can see.

Su Ziheng found Cai'er, handed her the "Barefoot Doctor's Handbook", and said to her: "Cai'er, you find a few people to find a way to copy this book, remember to use traditional characters, understand?" ”

Cai'er carefully took the book with the red coat and nodded, "Don't worry, master, I promise to complete the task." ”

Su Ziheng smiled: "I'll leave the matter to you, I don't worry." Tonight, you should first transcribe these descriptions of hygiene, and you can take your time with the rest. ”

As he spoke, Su Ziheng opened the manual catalog and pointed out to her the content that she needed immediately.

Cai'er hesitated for a moment and asked, "Master, if you need it urgently, then I will copy it myself, can I copy it with a pen?" Write it quickly. ”

Su Ziheng nodded and said, "As long as the handwriting is clear, it doesn't matter what you use, you can do it yourself." ”

"Hmm!"

While Cai'er was transcribing the contents of the "Barefoot Doctor's Handbook" on hygiene, Su Ziheng did not stop, looking for construction drawings for the construction of the reservoir and salt pans.

Since he wants to do it, Su Ziheng wants to do it in one step and directly come up with the most mature plan, which will be repaired in the future, which is too troublesome and a waste of time and energy.

……

……

In the past few days of Zhong Qinghan's absence, the old housekeeper Zhong Heyu has requisitioned an uninhabited mansion in Donghai County and opened it up into a temporary residence of Zhongfu, and after the official Zhongfu and Donghai County Princess Mansion are completed, they will be temporarily used by Zhongfu people to live.

After all, with the dignity of Princess Zhong Qinghan, it is not good to live in the inn all the time, and spread it out like that, what kind of system will it become.

After Zhong Qinghan placed His Royal Highness the Crown Prince and the Crown Princess properly, although she was tired from the boat and car, her body was very tired, and she had a meeting for half a day, she did not go back to her room to rest, but plunged into the study.

Donghai County is her own fiefdom, and she can't let Su Ziheng help her finish everything, but she sits back and enjoys it. She has to find a way to do many things herself, no matter how smart Su Ziheng is, he is only one person after all, and it is impossible to think about everything carefully.

This time, Donghai County recruited tens of thousands of workers from Jiangning Prefecture, although most of them came from construction projects, and only needed to sell physical strength.

But Zhong Qinghan thought about it, everyone's ability is always different, and they can't all rush to the construction site, it's best to divide labor to give full play to everyone's ability.

In the past, Zhong Qinghan led his troops to the battle, and what he was best at was to give full play to the abilities of each army, so that they could cooperate seamlessly and maximize the strength of the army.

In her opinion, directing workers to carry out engineering construction should be similar to leading troops to fight, and let each worker do what he is best at, so that things can be done quickly and well.

Otherwise, if you ask the stonemason to do the carpentry work, he will definitely not be able to do the job well, and he will lose time. It's like letting the cavalry attack the city, it's not that it can't be defeated, but that it will lose a lot of money, and the gains outweigh the losses.

Zhong Qinghan pondered for a long time, and she decided to post a recruitment notice at the entrance of the county government tomorrow, clearly distinguishing according to different types of work, and letting each worker sign up for the job he is best at first. Wait until the end, and then coordinate the distribution according to the results of the registration, and coordinate the group with more registrations to the group with fewer people.

Although this will waste a lot of time and energy, sharpening the knife without cutting wood, can maximize everyone's ability, Zhong Qinghan feels that it is still worth it.
