Li Er's troubles have nothing to do with Yang Qiao, Niu Baobao's troubles let Yang Qiao stop with one shot.

Well, since I don't know whose secret agent squatted on the tree of conscience opposite Niu Baobao, he was killed by Yang Qiao, and then, there was no then, as for whose secret agent this is, I don't know.

Originally, these people are like underground rats, well, they don't even have an identity, how to check, so it's just gone.

Well, poor bunch of people, but it doesn't seem to be possible without this bunch of people, does it!

"Niu Baobao, brother-in-law, I can't accompany you here, and you, let's settle down here, and the Confucian teacher will come to teach you from time to time, mathematics, let Luan'er teach you, well, your affairs, naturally have your manager to report to you, and I, will come to see you from time to time."

"Brother-in-law!"

Well, Yang Qiao was still ruthless and left.

"Princess, don't look at it, the colt is gone, he has a relatively large family after all, and it is impossible to be here all the time."

Seeing that Niu Baobao was a little unhappy, the female officer persuaded on the side.

"Well, let's go, let's go, it's not that I won't come back, today, the Lun family is going to eat a big bowl of rice."

Eh, I originally wanted to say that I wanted to eat elbows, but I suddenly remembered that this was keeping filial piety, well, in a semi-vegetarian state.

The so-called semi-vegetarian, this is Yang Qiao's stipulation, you can't be all vegetarian, nutrition can't keep up, and even the eldest grandson is not willing to watch the baby cow eat vegetarian in the sky, in fact, Yang Qiao is still a little worried about the body of the baby cow, or rather, Yang Qiao doesn't believe in this historical correction ability, don't correct the baby cow, so he, he still needs to see the baby cow often.

…………

"Spotlights?"

Well, it turned out that it wasn't that kind of car lamp, it was still split, it was a small bulb, with a reflective bowl, uh, in fact, it was this reflective bowl, and it wasn't there for a long time, but Yang Qiao made a few small spotlights in the pavilion when he built the embroidery building garden, which provided a direction for people, that is, inadvertently, Yang Qiao would take out something that was not there, and then, let people learn it, so it's okay, although they didn't invent it, they also observed it, and they worked hard.

"Lang Jun, the biggest use of this spotlight should be placed on the train, this train is fast, and the original light is not enough!"

This craftsman is very smart, the first thing that comes to mind is that it is used on the train, uh, isn't there a lamp on the train, there is a lamp, this, I can't help but say that Yang Qiao is a little narrow, just don't give them tips, so, that is, hang one or several large bulbs on the front of the car, well, it should be better than a lantern, but what, this bulb, that is, there is no long-range function, although, the life of this bulb is long enough, there is still no long-range function, this is not, this craftsman, once he invented this split spotlight, he thought of the train, and, Experiments were conducted.

"Because we haven't told Lang Jun before, we haven't really changed it, we just modified it on a locomotive we used at home, Lang Jun, come and see."

A locomotive at home?

Well, before or the earliest before a short locomotive, shunting used, later, it was not scrapped, continued to use, and even, some improvement tests were carried out on it, usually, it was used in the railway station for marshalling, and it was not out of the station.

"Lang Jun, look, right now, it's just cloudy, but you can obviously see the place where this light shines."

"Well, okay, continue the experiment, and, add this spotlight to the tractor and the baby car, naturally, in this case, there must be a large power and a small power, so study it well!"

"Tractor, too?"

"Yes, you don't know, there are lights on the tractor, but it's a pity, some, uh, forget it, you make a few lights according to these standards for me to see, the train needs to be powerful, you can use high voltage, and the baby carriage, and the lights on the tractor, give me twenty pairs of voltage lights."

This is considered a safe voltage, well, in fact, it can be higher, but it also has to be prepared for the battery battery in the future.

"Di Di Di, brother-in-law, the Lun family is going to turn left!"

"Wrong, wrong, you're right-turning."

"Hehe, Queen Mother, the Lun family is wrong."

The baby cow turned around and stuck out his tongue towards the statue of the eldest grandson, well, the baby cow has fully recovered, and is no longer sad for the death of the eldest grandson, and at this time, what is the baby cow doing, uh, isn't it, the baby car has a new improvement, that is, there are more turn signals, brake lights or something, uh, brake lights, it has nothing to do with the baby, but, turn signals, but related, no, Yang Qiao took a panel to train the baby cow, that is, baby cows generally don't go out of the yard, well, it's not always here, Occasionally, you can still go out to do things, but this improvement is not something you will be familiar with for a while.

So, Yang Qiao made a simulator for the control panel cab of the baby car and took it to the yard of the baby cow, well, that's how it was trained.

"Hehe, brother-in-law, aren't you busy, accompanying the Lun family here all day long?"

"I'm not busy, I can't let me do everything, so I have time to accompany you."

Actually, at this time, for Yang Qiao, except for exercise is a big deal, nothing else, there is no big thing, why, this technical thing, it will become a matter of explanation, mainly, some things have basically taken shape, what else can I do, is it, Yang Qiao needs to teach others to make the tube, and must make every kind of tube in the previous life, and this train, well, change the machine to improve, and improve again, do you still need Yang Qiao, no, just this spotlight thing, There is also the matter of the generator, there have been new changes, naturally, this, Yang Qiao just made a proposal.

Also, at this time, in the baby school, the baby car has also had a new change, fortunately, these babies, just touched the baby car, so, this improvement, for them, are new things, do not need to know anything, just know, there are turn signals, overtaking need to play turn signals or something.

"Toot, hey, I said, I'm really unfamiliar, this is another baby who didn't turn signal."

"Report to the officer, I didn't hit the turn signal, please punish you!"

Yes, the self-conscious baby turned to the side automatically and reported his mistake.

"Let's just say, aren't we as fast as these little babies are familiar with?"

"You are a good baby, I wrote down your mistakes, but you can say it yourself, what about me, reward you with a little red flower."

Little safflower, this is also a new incentive measure recently added, do well, there is a small safflower, and there are records, naturally, the punishment for bad work is still the same as before.

"Hehe, thank you, officer, next time I did something wrong, the officer didn't point it out, can I still get a little red flower."

Okay, this baby, you still want to take advantage, these women, can you learn well?

"Yes, yes, as long as you do something wrong, I didn't point it out, if you say it yourself, there will be little red flowers."

"What about others? Can I also tell the officer! ”

Well, this is a problem, the problem of the complaint, this, how to solve it, well, leave it to Lang Jun.

"To sue, or not to sue, Baby Niu, what do you think?"

Soon, this story came to Yang Qiao, well, it's still convenient to call.

"Brother-in-law, the Lun family thinks that this, it should be said, others are wrong, they are wrong, they must be pointed out, and they must be pointed out openly, if someone retaliates, then, it is our business, we, naturally, do not let this kind of thing happen, we must strictly deal with retaliation, this, you can also discuss it with your father."

What is this, the ball, kicked to Li Er again?
