After everyone had eaten, Li Yi went back to copy the book.

Li Longji and Li Chengji were standing outside and were bitten by mosquitoes, chatting by the way.

"Third brother, it seems that Brother Yi has a good face, do you want to make a move?" Li Chengqi felt that Li Yi was just holding on to face.

Li Longji shook his head: "No, I made a move in Lantian County last time, and only then did I know that Brother Yi has a complete set of layouts behind him." ”

"In this way, there can also be arrangements this time, we will arrange it first, if Brother Yi really doesn't have a move, we will solve it at a critical moment."

Li Chengqi thought about it, and it was indeed as the third brother said.

Last time, I thought that Brother Yi's trick was there, and sent Yao Chong out to lead the team in person.

Later, I realized that Brother Yi's pit had been dug and was just waiting for others to jump.

"I don't think we need it, Brother Yi will scatter to various squares according to today's method, or send someone to ask who wants to buy the newspaper and sign up.

There is no need to print 100,000 copies tomorrow, and deliberately sell 80,000 copies to Fanbang, there must be a plan. ”

Li Longji thought it was interesting, and he was guessing where he could get it back.

"Third brother, it seems that they are afraid of Brother Yi, otherwise they wouldn't have made a special move on a matter that is easy to crack in terms of money."

Li Chengji smiled, he felt the impact of the hot air balloon on those people.

It's just a newspaper, you can increase the price, more than the cost, what's the use of buying both?

In addition, sales are restricted, a person can only buy one copy, and you have the ability to hire a large number of people to buy, employment is not money?

Change a businessman, after today, deal with it immediately, how much money can be lost in the loss?

"It's in a hurry, there are rumors that Li Zhuangzi made a more powerful gunpowder weapon, put it on a hot air balloon, and kill a large piece."

Li Longji laughed along, and at the same time he was waiting, waiting for the foreign envoys in the Tang Dynasty to send the news back.

If the Tibetans were in a hurry and came to fight in a hurry, they would definitely fail.

In winter, they had just wiped out a lot of their main forces, and at the same time destroyed the main roads, and the morale of the Tang Dynasty was flourishing.

Tubo wants to build a bridge, and the army of the Tang Dynasty is guarding this side of the bridge, how to repair it?

If you don't repair it, you can only take a remote path to detour, and the speed of the march and the consumption of grain and grass ......

Or go around in a larger circle, so that the cavalry can come.

There is another method that seems relatively easy, send someone to infiltrate the Li family Zhuangzi.

Whether it is to catch Li Yi or get the hot air balloon design drawings and materials, at least it can be used against the Datang Air Force.

However, in order to return a child, Brother Yi exchanged his life expectancy for being able to see others clearly at night, but others could not see his own things.

yes, what's that?

"Brother, follow me to find Brother Yi." Li Longji thought of the problem and pulled Li Chengqi into Li Yi's courtyard.

Li Yi was copying medical books, and saw two people looking at the glass window, shaking their hands, and went over to open the door.

"Brother Yi, Brother Wei suddenly remembered that Tubo might be worried about hot air balloons, so he took two ways." Li Longji said directly.

Li Yi nodded: "One is to attack immediately, hoping to make Datang make any guarantees through war, and the other is to deal with me." ”

"Yes, Brother Yi, you can see other people's things at night, right? Show us and rest assured. Li Longji asked.

"Okay, two brothers come with me." Li Yi agreed, and took the two people into the monitoring room next to him.

There are four people in the monitoring room, and each person has a monitor in front of them.

Li Yi exchanged only one monitoring monitor, but he took three medical monitors, and this thing is now universal.

Connect wirelessly, and you can use it as another monitor with a single adjustment.

There are a total of 32 monitoring heads, each of which displays eight, so there is no need to switch back and forth.

It was dark outside, and lanterns were lit in some places, and people could only be seen in the circle where the lanterns were illuminated, but they were not bright enough.

The monitor in front of him made Li Longji and Li Chengji stunned.

In addition to the different colors, other aspects can be seen clearly, this is what can see people at night?

"It's too evil, Zhuangzi's guards are looking for places where there are no lanterns to place them, I have seen these places, and they are the most difficult places to stare at."

Li Chengqi found out about the situation, where it is easy to be touched, where there are no lanterns in important places.

It is clearly to tell others that it is safe to enter from here.

If you don't see it with your own eyes today, how can you believe that there are such strange things in the world?

"Good thing, so reassuring for my brother." Li Longji looked at it and said sincerely.

"And then cooperate with the upper feather forest flying horse...... Heck, since Fan Bang may fight Brother Yi's idea, this is not enough to just have things that can see people, and the army must also be enough.

Why don't I wait for a letter to Your Majesty and ask Your Majesty to arrange more people to come over, how can it be a major military event? ”

Li Chengqi said, finding that someone organized a strong attack with people risking their lives, what is the use of seeing it?

Li Longji echoed: "No matter what, you have to move Your Majesty, it's really not good, let's leave the guards." ”

Li Yi looked at the two people, turned around and went out, came back after a long time, and said to the two: "There is still a set of younger brothers, and the two brothers will take it back and use it."

It's just that there is only one display, which needs to be switched back and forth, and there is electricity, which can't be stopped, and there is a battery that can be charged, but it can only last for a quarter of an hour at most. ”

"Brother Yi, you, do you exchange your life?" Li Chengqi's face changed.

Li Longji also showed an angry look: "I'm waiting for it to be safe there, why do you bother ......"

"It's all changed, and if I don't change it in the future, won't it? The two brothers think about me, and I am also worried that something will happen to the Zhuangzi of the brothers. ”

Li Yi said sincerely, but he knew that this set of things would enter the palace in the end.

Who let Guo Ziyi come into contact with it that day, he is always remembered, it is better to take the initiative to take it out, anyway, his lifespan has increased a lot recently, and the consumption of this thing is very small.

"This, how does this make." Li Chengqun burst into tears.

Li Longji also frowned and gritted his teeth, his fists clenched.

"It's okay, I have a way to maintain my health, and I can recover slowly." Li Yi said.

The two of them didn't believe it, they just thought that Li Yi was comforting.

"Oops!" Li Chengqi slapped his thigh hard.

Li Longji said to Li Yi seriously: "If you want to change things in the future, you must talk to Brother Wei." ”

"Okay, third brother." Li Yi nodded.

"But this kind of good thing, you can't take it for your brother, it's troublesome to take it, and you will dedicate it to Your Majesty for the brotherhood, and Your Majesty will be happy, and you can't send Yu Linfei to protect your brother."

Li Longji spoke again and made the arrangements clear.

"Huh? Yes! Li Yi looked surprised at first, and then said that he understood.

Next, Li Longji learned in the monitoring room, how to use it, solve the problem of electricity, and solve it by manpower, as long as the upper limit of voltage and current is reached, it can always be stable.

This upper limit is the upper limit of the output power of the human-powered generator, which is at the highest place and can be compatible with the equipment below.

If it's too big, the equipment below has its own substation regulator, and that's no problem.

Li Longji listened and said that he understood, and said that he would explain it clearly when he read the book.

He was really greedy for this surveillance, but he didn't want Li Yi to change it.

Well, now the palace is stable, unless something goes wrong with the person watching the surveillance.

He decided to send five hundred feathers of Lin Fei to ride here, in case someone was really in danger, he didn't need Brother Yi to exchange his life for any weapon to resist.
