"Lang Jun, you say, if this hot air balloon is used to command the artillery below?"

Looking at the latest surveillance hot air balloon arranged by Yang Qiao for the Science and Technology City, I was a little excited.

Well, the hot air balloon, all along, this hot air balloon, that is, after being transported several times, is basically useless, that is, there is no suitable place to find the hot air balloon, the most important thing is that it is difficult to control, in the air, the air flow is more chaotic, and the control of the hot air balloon is troublesome.

That's because of this, so, this balloon, well, Yang Qiao handed it over to a few craftsmen and set up a balloon research room, uh, for so many years, there are almost no research results, but they are still continuing to invest money, continue to research, well, in the middle, it is not in vain, transportation, how many times.

No, this day, this research has a little bit of fruition.

"Lang Jun, you said, if you use this balloon as a battlefield surveillance, will it work very well!"

"Well, I think I've used it!"

"I've used it, but this time it's different, no, there's a phone, this command, you can use a phone or a flag to command."

These craftsmen are all a little anxious, and others have made achievements, and they are the ones who have made these achievements, hey, speaking of which, they are all tears.

"Alright, alright, let's put this balloon in this city first, and use it as a surveillance."

No, in this city, a hot air balloon is released every day, and as long as it is a good day, this balloon will rise.

"Attention, please note, it's three o'clock today, well, that's the early morning, Nanshan, enter three woodcutters, but, it seems, four don't look like woodcutters."

That, you come down, I won't kill you, enter the three woodcutters, four are not like woodcutters, you don't know how to count!

"No, you didn't look at yesterday's records, there was another woodcutter, he didn't go back, isn't it four, as for why they said they were woodcutters, that is, they had a flat pole, a sickle, and cut branches, but they didn't tie up the branches, and finally left, and the branches were thrown in the woods."

"Haha, haha, on the top of the East Mountain, there is a woodcutter who was struck by thunder."

That's it, in this city, there is such a surveillance balloon, all day long to watch woodcutters, or to watch mushroom picking, well, it's okay, it can be regarded as finding out the law of some surveillance personnel.

"Lang Jun, look at this surveillance map, the people of the saint, an average of two people a day, there are five people, there may be some big families of the gate lords, and there are three, they are here to pick up cheap small families, and there are a few, it should be mountain bandits, I want to see the opportunity to rob, this is not what we are doing here."

"So, the balloon worked?"

"Well, Lang Jun, it works, it's better than monitoring it on the gatehouse, the gatehouse, you can see not so much of a range, often, and you lose it, but what about this air, that's all-round observation, and even, you can even cooperate with the gatehouse to observe."

With the gatehouse, it is naturally a telephone.

"East Gate, East Gate, there are three people, who have entered your surveillance range, please pay attention to observation, pay attention to observation."

"Understood, they went into the sewer, the sewer, let people release the water, haha, haha, the soup chicken is here."

Although, this sewer may not be able to enter the person, but, if this person hides here, and then thinks of any way, it is useless, right, so use the water release to deal with it, originally, this release of water, is also necessary, however, this release of water, is generally at a fixed time, the excess water, to let out, let it flow into the river, or somewhere.

Well, the sewer, as I said earlier, this sewer is stored with stone and sand on the side, and is used as a storage pool, and when there is more water, it will enter the sewer, and then, it will flow out, but at this time, in this city, because some green plants have grown, this water storage, and there is one more place, so the water flowing out of this sewer is even less, and there are more gates, and this gate is to deal with these not long-eyed, this is not, commanding, just put some water, although the impact is not big, However, it will also be filled with a full water.

If they're here to hide or something, well, it doesn't matter, if it's a spy or something, naturally, someone will go and arrest them, and even if they don't, there will be an excuse to deal with them.

No, at this time, when Yang Qiao came to look at the cannon again, the city defense manager had another idea, as an artillery commander, well, this idea is good, but at this time, this cannon, this shooting distance, do you need to use this balloon cannon aim!

"Do you need to use it, I think, isn't it across the woods, originally, you can't see the other side, we still have to use the city tower over there to command, if you use balloons, will it be more convenient."

Eh, the commander of the castle tower?

Naturally, it is also for cooperation, and even, or for this command problem, every time this cannon is tested, it is commanded on the city tower, that is to say, it is a long-distance command, and even, even the command tower has not been established, originally, Yang Qiao suggested that a command tower be built, not only as a command tower, but also as a lightning rod, well, not built, but used as a city tower.

Castle Tower, how to command.

That is, at the time of each test, the phone of the city tower will be pulled, and in peacetime, this line is not used, well, the combat unit, what is the connection with the test unit.

"Distance, 1,200 meters, target, target number three, left, thirty from the ground."

Well, although, on the opposite side of the terrain, every time it is built, there will be a map, but this target is placed casually, and it is also marked with one, two, three, four, naturally, this target will be hit next to each other.

"Report to Lang Jun, the place where this target is located is not suitable for command, it is too close, if it is outside the city, or on the mountain outside, it can be commanded, but this is too close, and the height difference cannot be seen!"

"Report to Lang Jun, there are thunderclouds coming from Dongshan, please instruct to descend!"

Thunderclouds?

As mentioned earlier, here, there may be a mining area, so there are a lot of thunder, otherwise, there will not be so many lightning rods in this city, well, however, this thunder has really not hit the city, and even, this balloon, in the sky, is rarely hit, why.

Well, isn't this here, it's a mountain col, although it is far away from the surrounding mountains, but Yang Qiao still inserted a lot of lightning rods on the surrounding mountains, so this thunder led away the mountains on all sides, which is also the reason why the balloon was observed to be struck by lightning.

Well, for this reason, some outside observers, many of them, were killed by thunder, and even caused a panic in their family.

Don't panic, you can't do it, you are struck by lightning, who is often struck by lightning, you say, hide in Nanshan, Nanshan is struck by lightning, hide in Beishan, Beishan is struck by lightning, the main reason is that their light helmets are struck by metalwork, they are not struck by lightning, who is struck by lightning.

"Lang Jun, you said, there are so many surveillances every day, what's going on, do you want it!"

The city defense chief made a motion to wipe his neck.

He was a little annoyed, and he had to guard against these people all day, and he really felt very troublesome.

"What's the trouble, even if it's for you to train the army, but don't let your guard down, we are here, internally, it's not a secret, but, to outsiders, it's a secret, but it's a lot, any of them are secrets, it's all money, if someone steals it, what money do we make?"

Remember, they are not within a certain range, we don't need to arrest them, and if they are within our control, then we don't have to explain them, even the holy ones.

"Lang Jun, this balloon commands the artillery, don't say it, but, here, why build such a good house, and then, let the cannon be broken, use a model, can't it?"

"Until now, you still don't understand why it's like this, isn't this to exercise your two skills, one is the technology of artillery destruction, and the other is the technology of construction, why, for this, do you still care about these things, the front, the few guns you sold, did you get back a lot of money!"
