"What's your alternative?" Liu Che asked with curiosity on his face.

This kind of thing shouldn't have been asked on such an occasion, but there is no way, the addiction of pretending to be forced has come up, so naturally it can't be managed so much.

Besides, how awesome the strength of the Han army is now, Liu Che is not without force in his heart.

The big men are so awesome, what can I do if I am arrogant?

Even if Liu Ponu told his method in public, what could it be?

Can they learn or what?

Moreover, if it was really so easy to be learned by them, would Liu Ponu's character still say it?

Therefore, Liu Che felt that he was just going to be cool.

How to be cool, when to be cool, how long to make it cool, that's what Liu Po's slave should worry about, what does it have to do with me?

"There are many alternatives, but I'm too lazy, so I chose the most convenient and direct plan!" Liu Ponu smiled.

Can you still stump yourself on such a thing as an investigation?

Even if you don't use your brain, you can come up with a way to deal with it casually.

You know, this was in the Han Dynasty, not in the afterlife.

As long as it is a method that I have come up with based on the experience of later generations, even if it is completely useless in later generations, it is still advanced and an unmanageable solution to be put here.

Liu Ponu's words also aroused the curiosity of the Manchu civil and military forces, if the reconnaissance could be done so easily, this battle would not have to be fought for so many years.

After more than 10 years of all-out warfare, the difficulty lies in finding the enemy's position.

Especially in the grassland, once you get lost......

Well, Li Guang has the most say in this regard......

"Wouldn't it be okay to send people to heaven to see them?" Seeing that everyone's curiosity was aroused, Liu Ponu suddenly said amazingly.

"What?"

"Nonsense, it's just nonsense......"

"It's over, the prince demon is stunned......"

"Did you kid not wake up or what? Could it be that the lake is burned? Even Liu Che felt that Liu Ponu's method was simply not too spicy.

I've gone a lot of crooked paths, I'm afraid I don't even know how to go on a normal path, right?

And send people to heaven?

Why don't you send people straight underground?

Really, when you can go to heaven and earth?

"Hehe, give me a month or two, and I'll send people to the sky for you to see!" Liu Ponu smiled, but he didn't care about everyone's doubts.

The plane didn't have the ability to do it, and Liu Ponu didn't expect to do it.

But can't you make a hot air balloon?

As for the problem of fuel, can't you fly without propane or liquefied gas?

The hot air balloon is actually an enlarged version of Kong Ming lantern, the only difference is the material.

Kong Ming lantern can be raised to the sky with a single candle, can't a hot air balloon be sent up with coal?

Of course, the disadvantages are not without it, such as the heavy coal and the limited weight of the hot air balloon.

For example, coal does not have the injection capacity of propane and liquefied gas, and neither efficiency nor mobility can be compared with propane and liquefied gas.

But is that the problem?

First of all, it is necessary to determine the current positioning of the hot air balloon, and the positioning given to him by Liu Ponu is to reconnoiter the surrounding situation.

So, is it important to ask whether the hot air balloon can control its movement on its own?

Is it hard to solve the problem of mobile?

It's a big deal that I tie him to the car with a rope, and let the car pull it if I want to move.

You don't need to carry too much coal, and when you need it, you can just send it up in a basket little by little.

"The Legend of the Fairy Tree"

In the plain area, it is not an exaggeration to say that a person standing on a high place twenty miles away from Chang'an, does not need to be too high, as long as there is a height of six or seven meters, when the weather is good, you can clearly see the outline of Chang'an City, and even the location of the city gate tower.

Although most of the grasslands are not plains, the height of the hills is not too high.

Standing on the grassland, people's vision will be blocked by the hills, and even if they stand on a high place, they will not be able to see the back of the hills at all.

But what if you put him fifty meters, or a hundred meters in the air?

To put it mildly, with the current state of the environment, it is as easy for people with good sight to see forty or fifty miles as if they were playing.

Of course, that distance will certainly look like a lake.

But what Liu Ponu wanted was not accurate reconnaissance, he didn't need to find exactly where every enemy was hiding, and the Huns never acted alone.

Tens of thousands of people are moving below, even if you can't see forty or fifty miles away, twenty or thirty miles should be no problem, right?

With this thing here, the Han army next is like opening the eyes of the sky, how the enemy is deployed, where it is moving, and how many people there are, can be seen clearly.

Put a hot air balloon on the alert, as long as the people on the hot air balloon don't fall asleep, the whole camp can go to sleep peacefully.

Even if the enemy is found, everyone can still have a meal and prepare for defense without hurrying.

As for the big target, easy to expose your position or something, this is even less of a problem.

The current Han army can't wait for the Huns to take the initiative to attack, and it just takes a lot of effort to toss back and forth by themselves.

Therefore, if you engage in hot air balloons at this stage, although there are many disadvantages, his advantages are obviously more.

Looking at Liu Ponu, who was full of confidence, Huo Guang gradually fell into deep thought.

If once was an accident, then what about two or three times?

Is it possible that it is an accident every time?

Regardless of whether others believe it or not, Huo Guang doesn't believe it anyway.

And this time, in order to refuse his proposal, Liu Ponu even said this kind of ridiculous nonsense, which was enough to make Huo Guang, who had keen senses, realize the seriousness of the problem.

And this couldn't help but make Huo Guang's heart startled, and secretly shouted that this is not what is wrong, Liu Ponu, this kid, began to be wary of himself?

The smart Huo Guang had already realized that Liu Ponu was targeting himself by doing this, to prevent himself, the future ruler, from being too inflated, so as not to let himself develop into a relative like Tian Wei.

It's just that......

Huo Guang really wants to tell Liu Ponu, your father-in-law and I are really different from Tian Wei, I have a cultural background, I have the bottom line of a cultured person, and I can't do that kind of shameless thing!

But Huo Guang had no way to say this kind of thing, he could only swallow the bitterness into his stomach silently and bear the consequences alone.

And this time also made Huo Guang realize that Liu Ponu's kid is really not simple, not only is he unwilling to suffer, but even the sophistication of the world is clearly arranged.

What's on your mind?

He can tell at a glance whether you are serious about your work or not, and he can still see it at a glance.

What you think of and what you can't think of, he can think of before you.

And he can not only think of it, but he can also arrange it for you in advance, so that it will be difficult for you to find a crack to drill at that time.

Liu Ponu is now clear that he wants to cut off his connection with the army, so there are only two roads left in front of Huo Guang.

Either honestly obey Liu Ponu's arrangement and take the initiative to cut off contact with the army, or just wait for Liu Ponu to forcibly cut off, but without the support of the army, is he still Huo Guang?

Thinking of this is a headache, this is not necessarily a good thing for a monarch who is too shrewd!
