A battlefield autumn soldier that Li Er had prepared for a long time, in this accident, it ended a little awkwardly, why is it embarrassing, that is, the host has changed in the back part, and Yang Qiao has come to command.

And Li Ji, there is no need to discuss, this, it is Li Er's business, he himself convicted Li Ji, well, it's not bad, Li Er has been in a good mood in the past few years, so Li Ji just lowered a lot of levels, you go to see the city gate!

In this way, Li Ji became a city gate official.

"Oh, it's so dangerous, it's so dangerous, I was almost punished by the three clans, the city gate official, can you either!"

This talker, what is wrong with you going to scan, why are you telling me other people's jokes?

"Scanning, naturally there is the meaning of scanning, do you know, in the past few years, your task has been a lot less, do you know why, today, I have a definite reason, that is, in the past few years, I have scanned a little less, so, this information is also less, no, today this scan more times, this task is here again, Di Di, Di Di, today's task, I am free to announce, boy, do you need to accept the task, in fact, this is also a vain question, accept it, or not, this is also a mandatory task, that is, This is a task that you have to complete. ”

This is a long-winded pass, that is, there is another task for Yang Qiao.

"Okay, okay, don't listen to your ramblings, you say, what is the mission!"

"The task is to improve the bamboo rocket launcher and rocket, and if it is completed, there will be a reward."

"Husband, my father has another message."

Before the conversation was finished, the news of Li Er came again, could it be that this tuberculosis was fighting with Li Er for a task, sure enough.

"Husband, look!"

Li Lian put a note in Yang Qiao's hand.

"Help me improve that rocket!"

It's a few very simple words, and sure enough, it's a chatter who is competing with Li Er for a task.

"Talker, what is this?"

"How to say it, His Majesty the Emperor, it should be that the effect of this rocket is a little worse, or, there are other ideas, and the system, is that it is believed that the research and development, utilization, and development of this gunpowder have a standard pole, so there should be upgraded products, so this task is given to you, naturally, this is a mutually beneficial thing, I have already told you before, now, my system, and you are a collaborator, so we are a win-win situation."

"Bamboo rockets, copper hoops!"

After Li Er's approval, Yang Qiao saw this relatively new weapon.

"Yes, it is this bamboo tube and copper hoop that has your task, you didn't find it, is this a heritage, there is no intermittent inheritance, if it is an iron hoop, then, this inheritance is broken, and there is a copper missing in it."

Looking at these weapons, chatter was also explained in Yang Qiao's mind.

"Instructor, you see, this weapon is processed by the most traditional process we use, such as this bamboo tube, first use tools to open the joints inside, and then use grinding rope to polish the inside smoothly."

"The original tool, isn't there a new tool, why don't you use it?"

Yang Qiao was very puzzled, this, with a new tool, do you have to say it yourself.

"That, instructor, we, none of us will, but, apply for technical personnel, no, we haven't passed, so, let's do it ourselves!"

Well, sure enough, no matter what kind of intelligence, there is no news about the spread of these weapons, and no one has succeeded in copying them, not to mention those small countries on the side, even some big families inside, there are also imitations, but unfortunately, they have become fireworks.

What about this, improvement, Yang Qiao has not improved much, unless it is completely changed, but, according to the meaning of the talk, this, according to the order of inheritance, is the best, then, only according to this bamboo tube, in fact, this is really the best, if the middle step is skipped, well, now give a real rocket launcher, iron cylinder, not to mention hundreds of miles away, it is five miles away, is this useful, five miles away, the city wall was broken, and then, when the army arrived, everyone ran out, Harvested an empty city.

Therefore, two hundred meters, at most three hundred meters, however, it is better to fix this distance, at most use the angle to control the distance, then, now, the first thing Yang Qiao determined is to fix this medicine powder and formulate it.

In other words, he has not continued to pay attention to this formula problem since Yang Qiao gave people to develop this gunpowder, so he doesn't know whether this formula is good or bad.

Therefore, the first task is to distinguish the explosive charge from the jet, fine-tune it, and determine it.

So, this distance is fixed, and then, it's a matter of power, and the original effect is to add some iron nails or something to the gunpowder, and it's a volley explosion, well, so within a certain range, the lethality is still good, and, they inadvertently got such an effect, that is, killing, in fact, it's better than killing, for example, the rocket head exploded, and as a result, it injured more than ten people, don't count too much, well, more than ten people were injured in the head, most of them were eyes, so, Of these more than ten people, at least five people need to wait, otherwise, it will be in the way on the battlefield, so it is better than killing, killing, and throwing it aside, but this killing and wounding will consume vital strength.

So, this effect, Yang Qiao still has to inherit it, but, this effect, is inherited, this is a kind of arrow, and there is a second kind, that is, a rocket, well, a very old tactical weapon, but now, Yang Qiao took it out again, that is, to add some small oil bags to this arrow part, that thing, but after a special formula, once it bursts, it will burn, and where it sticks, it can't be taken down, and it can't be extinguished with water, unless it is made of sand, um, which came to the anxious, where the sand came from, and, who could begin to study out the fire with sand.

The most important thing is that Yang Qiao improved the processing equipment, that is, this manual saw, changed to a power woodworking saw, and then, the copper hoop, changed to an iron hoop, this iron hoop, made a lot in advance, and this iron hoop, is not manually installed, but there is a kind of Yang Qiao new press to press up, when the press is installed, and then, only through the bamboo tube, the inside is finely grinded, this becomes a new bamboo tube launcher, originally, a few days to make a launcher, why a few days to make one, why a few days to make one, The main thing is that there are too many invalids, but now there are new control production machinery, no, dozens or hundreds a day, it is very easy to manufacture, that is to say, after a battle, this launch canister, will waste a lot, I don't care, that is, almost it is a canister, just fire an ammunition, and before, there are often people injured, that is to burst, in order to save, isn't it with a canister, a few ammunition are fired.

"Father, what about this, it's called the Son and Sun Cannon!"

A month, Yang Qiao used a month, and the bamboo rocket was simply upgraded and improved, no, this day, let Li Erlai test it again, well, this time, it used a reserved open space outside the Chang'an city wall, more than 500 meters away from the city wall, and people are watching with telescopes, and even, in the periphery, it is fenced with engineering planks, oh, this fence, its usefulness is not big, no, on the city wall, what Goguryeo or something's envoys, have also been invited, but, They didn't have any binoculars, they could only see with their eyes, and they could still see clearly, and in the distance, there were simple houses, and makeshift walls, and some pigs, well, pigs with iron armor.

The first item to be shown is the rocket, which is what Yang Qiao said about the Broken Son and Sun Cannon.

"Why is that name?"

"Father, just take a look."

As he spoke, Yang Qiao raised the flag in his hand, that is, he began to indicate in the flag, and in the distance, there was also a soldier looking at this side with a telescope, and when he saw Yang Qiao's instructions, he first replied to know, that is, he received the order, and then, he blew the whistle in his mouth, and commanded with the flag, and then, four bazookas fired four rockets at the same time.

"Snort...... Syllable! ”
