"The main branch of electrons, this time, you should understand it, what is the reason for the main branch?"

"Well, this time, some people understand, it should be your people, who understand the use of magnetoelectricity, as well as the use of resistance capacitance, as well as the pickup and transmission of sound, or the pickup and transmission of waves."

Chatter gave an unexpected answer.

"No, the front, the generator, the motor, isn't it the use of magnetism, and the music box or something?"

"This, you said, how many principles are explained by you, naturally, it's not that they take the initiative to understand, so, this time, it will really light up the main branch, and, don't ask me, what kind of specific should you prompt, it is considered to be active understanding, what is it, it is not active, this, I can't say clearly, I just know the ratio, but how to calculate this ratio, I still don't know."

"Oh, then I won't ask you."

"Lang Jun, Lang Jun?"

"Ah, very good, very good, in this way, what about you, first help this kid study how to pick up some musical instrument tunes, and even singing into this film, and then, make this thing smaller and play with the dolls, but, for the dolls, just shake it, boy, here, I'll leave it to you, how to sell it, you look at it, yes, and this."

Yang Qiao suddenly remembered that the towers of those large clocks and watches had also begun to be built, so this big wall watch also needed to be manufactured, so, soon, Yang Qiao gave a size, yes, that is, the size, the specific style, naturally they had to study it themselves, and it should be in line with the vision at this time, isn't it.

"Don't worry, Lang Jun, we will definitely not delay these things."

…………

"This is Chang'an City, but what about the Imperial City?"

On this day, Yang Qiao had not yet arrived, Li Er had already arrived first with a group of students, and Yang Qiao also sent someone to send the sand table of Chang'an City first.

This sand table, if you say one, it is better to say that it is more than one and a half.

This Chang'an City is the main sand table, and on the four sides, there are a few small mobile sand tables, since the offensive and defensive battles, there can be no equipment outside the city, so the outside of the city is also given a certain amount of ground, however, there is no reserved territory for the other party to camp.

"You said that the place where the camp is stationed, there is naturally, it is another choice, when the place where the camp is chosen, we are connected to the sand table of the place, besides, the sand table of the other party's camp is placed in another room, and the four moving sand tables around this are one of the battlefields, so."

Yang Qiao introduced this sand table.

"As for me, one more digression."

Suddenly, Yang Qiao became serious.

"I teach you the tactics, then, you also have to remember what I said earlier, I can teach you, I can take it back, this Chang'an City, ah, no, is the new Chang'an City, it is the place where I Yang Qiao defended, as long as there is anyone who wants to be tempted here, maybe the saint is merciful, but I can't, others, I don't care, I taught it, I tell you, if you make a mistake, I will destroy your nine clans, whether you are male or female, remember, so, saint, you can rest assured, this Chang'an City attack and defense is just the most difficult offensive and defensive battle, otherwise, There is no point, besides, isn't the place in this imperial city empty, this last line of defense, you should know it! ”

"Well, I also said a few words, you are all here, naturally, it is my most trusted subordinate, I will not believe what Yang Xiaozi said, but if it really happens, I will destroy you alone, but I can't guarantee that Yang Xiaozi will destroy your nine clans, in the end, this is an advanced tactic, if anyone thinks that it can't be done, they can quit, I still believe in you."

Li Er also interjected a sentence at the right time, in fact, isn't this a guarantee given to him by Yang Qiao, dealing with you is very simple, but I won't do that.

"Come on, Holy Lord, in order to demonstrate the use of this sand table, I will let the staff officers demonstrate it first."

"General!"

"Well, you guys, let's draw lots, draw to the red, enter the red war room, draw to the green, enter the green war room, the same way, the heralds, and the pacesetters, and the referee into the referee's room, and the saint, and Principal Li, we also enter the referee's room, the eldest grandson, you also come, the other people, all enter the viewing room, you can discuss, Shengshang, this, the viewing room, you can arrange for people to record their speeches, you can discuss in the viewing room, you can also make noise, but you are not allowed to fight, okay, Let's take our seats. ”

"Yes, General."

This time, Yang Qiao used a lot of people, even the soldiers, there were nearly fifty people, and these rooms are relatively large, however, it is better to say that it is an open shed, this referee room and the viewing room are directly with glass windows, you can see the sand table outside, and the two war rooms have no windows, only one side door, as long as people don't come out, you can't see the sand table, in these two war rooms, you can also put the sand table, you can also hang the map, and at this time, it is the map that is hung, because, it can almost be said, Who doesn't know the terrain around Chang'an very well, so the battle can be done as long as the map is used, and there is no need for a sand table.

"General, do you want to start fighting now?"

"Let's get started!"

Li Jing looked at Li Er, this Yang Qiao was too bold, he didn't ask Li Er for anything, did he put this emperor in his eyes!

"Alright, pharmacist, I know what you think, didn't you just ask me, boy, you can explain."

"Back to the saint, into this combat deduction room, it can be said that even on the battlefield, since the saint is not a commander, just a spectator, so, at this time, you can only protect the emperor, and you can't say that you ask the emperor, if you ask for everything, then, it will delay the war, and the saint only asks for victory, victory, not anything else, besides, no one does not respect the saint!"

Soon, the two referees walked out and sat down on a relatively high platform.

"Shengshang, these two are on-site referees, and the ones inside are the global referees, not only playing the role of referees, but also recording and analyzing their actions."

At this time, several referees inside are also in place, the same, on the side, there are a few soldiers running errands, on the side, there is also a relatively large map, there are a few plates on the side, there are small flags, solid lines, dotted lines and some indication marks, all with a very thin nail on it, can be nailed to a specific position on this map, that is to say, on this map, there are some nail holes, just to nail these things, under the premise of no other measures, temporary, Yang Qiao also came up with this way, Extend the life of these maps.

Outside, there are referees who let the two sides guess, the purpose is to know who is the attacker, who is the defender, and what aspect the attacker should attack from, which also needs to be guessed, and what technology the attacker and the defender will have, the so-called technology, is naturally the use of weapons.

"Squeak......

As soon as the whistle sounded, the doors on both sides immediately opened, and then, one by one, the soldiers wearing masks ran out, and then quickly placed small flags on the sand table.

"Boy, what are you doing?"

"Holy Lord, before the battle, naturally there were scouts in action, naturally, because it was a combat confrontation, so, those original guards and other things, there are no more, these are considered to be the things of the city guards, and it is none of my business."

The soldiers on both sides ran very fast, and soon, there was a matter of hand-to-hand combat, so there was one more content, that is, the referees on both sides began to send signals to their own soldiers, so that the fighters inside knew some news they should know.

"Okay, good, good, this method is good, this sand table can also be used like this."

Li Er applauded here at the same time.

"Come, you kid, explain to me what it means."

On the other side, Lao Cheng was also anxious, so he pulled a soldier who wanted to explain and began to ask.

"General, don't worry, I'll explain it slowly."

This soldier was a little crying and laughing, no wonder beforehand, the general said, to endure, the generals here, there is no good temper, this bad temper has not been seen, but the quick temper has been seen first.
