After listening to Liu Zhang's words, everyone understood the role of the lines on the surface of the original bullet case.

"Also, it's this string here. You need to add a back cover to seal this cable inside. Exposed to the outside, it is easy to cause accidental injury. ”

Liu Zhang put forward another suggestion for improvement.

When everyone heard this, they all nodded yes.

Since it is necessary to weaponize, everything must be taken into account.

From production to use, everyone went through it again in detail to ensure that there were no problems, and then the final product sample was decided.

"The other thing is to keep it secret.

Not only should the management be confidential, but also the design, production, and all aspects should be kept confidential.

This research is currently the highest secret in Yizhou, and the results of the research will also be the highest secret.

The production of this grenade was to be produced separately, and the gunpowder, components, and lighters were to be produced separately, and finally assembled by one unit. The formulation and production of gunpowder, the specification design of components, and the design and composition of the ignition device must be kept strictly secret, and the whole must be kept secret.

Moreover, the Academy of Engineering Sciences will have to take into account some confidential designs in the future. ”

"Secret design?" Huang Chengyan asked puzzled.

"Hmm." Liu Zhang nodded and said: "The so-called secret design means that even if outsiders get this thing, others can't imitate it, unless they can unravel the secret design." Our grenade has no secret design now, and it is still possible to imitate it after others get it. ”

When everyone heard this, they all frowned.

"What does the lord mean, do you have to design a lock-like thing, and only when you open the lock can you see the real thing?" Huang Chengyan asked.

That's what it means. For example, if this grenade has a design, once someone wants to take it apart to see the design inside, it will explode as soon as it is opened, it will be perfect. Even if the enemy gets a sample, they can't open it to see what it's all about, and they can't copy it. Unless they have full access to our production process and design drawings. Liu Zhang explained carefully.

Huang Chengyan thought for a moment and said, "This is easy. In this warhead section, we add a firefire design, and the ignition lead is connected to the shell. As soon as the two halves of the shell are snapped, the lead will be attached to the shell, and if someone forcibly dismantles the shell, the lead will be touched and cause an explosion, which is equivalent to automatic destruction. ”

"Good, good. According to Huang Gong's meaning, add another layer of insurance. In this case, even if someone else takes it, half of it will not be able to be copied. Then there is the production management, which must also be strengthened. ”

Everyone nodded yes.

"With this thing, our army's march into Liangzhou is just around the corner."

Liu Zhang said that it was just around the corner, and the result was more than a year.

A year later.

Mei.

"Uncle Zhong, how far is it to Hanzhong?" A handsome boy of thirteen or fourteen years old asked a middle-aged man who looked like a shopkeeper.

"Childe, I will arrive soon, after Meixian, the sloping valley in front, and after walking through the Bao slope road, I will arrive in Hanzhong. Childe, it's hot, is it not too late for our caravan to rest in Meixian for two days before leaving? ”

"It's almost here, I don't think it's going to delay, get more dry food and water, it's important to hurry." The young man was in a hurry to leave.

"No, then I'll give you the order to go down, and everyone will continue on their way."

The caravan, with a dozen vehicles, continued on its way.

Passing through the county seat, not far ahead, is the outpost of Cao Jun.

"Stop, stop! What for?! ”

"Master Jun, we are in business, this is our Guan Wen, there is the big seal of Jingzhao Mansion, a few military masters, please take a look."

"Go, go, go, go, go, don't you see that the sun is in the west? Come back tomorrow. "The guards at the checkpoint were very impatient.

The man named Uncle Zhong hurriedly stepped forward, took out a handful of money, and stuffed it into the hand of a soldier, "The military master has worked hard, take it to make a pot of wine for the brothers." Master Jun, we're in a hurry, so let's make it convenient. ”

The soldier looked at the money in his hand and said with a smile: "I see that you also seem to be a person who knows things, why are you so ignorant, is this little money enough to drink for the brothers?" Besides, the brethren are not short of your little money, and it is not good to break the rules for your little money. You'd better come back tomorrow, but remember to come early, we only release 50 merchants a day, so don't blame me for coming late. ”

"Fifty?" Uncle Zhong looked at the back of his caravan, and just looking at this team, there were more than fifty merchants, so he hurriedly asked, "Are these fifty places in the order of first come, first served, or are there any vouchers?" ”

"Okay, you're smarter. Since you asked, we won't hide it from you, the fifty places are naturally based on the voucher. ”

Uncle Zhong listened to the other party's meaning, estimated that this voucher and the like would definitely cost money, and asked again: "Master Jun, I don't know if this quota is still available now, how much money is needed, Master Jun just needs to speak." ”

"Okay, enough eyesight. Let's tell you the truth, there are only two places left, how much is it, you look at it, and if you start with hardware, you will look at it. ”

Hardware? Do you need hardware to pass a level?

After walking such a long way, I haven't earned a penny, and the money spent on passing the customs along the way is enough to buy a few truckloads of food.

However, the ninety-nine bows have passed, and it is not bad for the last few tremors.

Uncle Zhong had no choice but to take out a small piece of gold cake and put it in the other party's hand, "Master Jun, it's good, we want one of these two places." ”

The soldier checked the gold cake in his hand, a little embarrassed, "It's not that we don't know each other, but it's a pity that there are really more people and fewer wolves." ”

Uncle Zhong was helpless, so he had to find another piece of gold cake, ten gold, and stuffed it into the other party's hand, "Master Jun, it's okay, we're really in a hurry." ”

The soldier smiled at this time, "Okay, it's refreshing enough." Since the elder brother is so refreshing, the brothers will not be lazy, you have this brand, remember to come early tomorrow. In addition, let's send you another message for free, do you want to hear it? ”

Uncle Zhong took the sign and asked cautiously, "What's the news?" ”

"I think you are like a merchant who comes to Hanzhong for the first time, we have to warn you, Hanzhong is not as good as other places, not as good as other states and counties in Hanzhong, Hanzhong uses the law of Shu, and the law of Shu is self-contained, you have to be careful step by step."

"Thank you for the reminder."

"Don't be too busy, I haven't gotten to the point yet. The town where our level is located is called Seven Heroes Town, it is said that Jing Ke wanted to leave and other seven knights came to this town, opposite the town is the valley, and the level of the valley is the level in Shu. What we mean by this is that half of the town belongs to Fufeng and half belongs to Hanzhong, so you might as well go through the procedures for local residents in the town, and when you arrive in Hanzhong, you will be regarded as a local business, in that case, it will be much more convenient to do anything. ”

"Oh, there's such a thing? Thank you for informing me, thank you, thank you. (To be continued.) )
