Several carrier pigeons flew from the scene to the outside of the city and quickly disappeared into the night sky.

An hour or two later, the information brought by the carrier pigeon was sent to Li Dingguo's case.

Sitting in front of the desk, Li Dingguo slowly pushed away the information from his eyes, slowly stood up from the desk, and paced around the office. He was thinking about the information brought by this intelligence, he stood in front of the window, looking out the window, on the wilderness outside the window, you could see a large group of troops gathered in the wilderness, since the siege of the city, 80% of the army of the Western Expeditionary Army has gathered under the city of Jingnan, now, everything has been prepared, only the last step is missing, this last step, is purgatory, or heaven.

The answer is unknown, but one thing is for sure, they will have to be well prepared for that day.

Some of the preparations even began more than twenty years ago!

More than 20 years ago, it was already counted today!

When King Jin was thinking, Gao Shiqi looked at his back in his mind, there were still countless questions, but in addition to the doubts, he was more surprised, even if it was Junzheng, even if it was the person in charge of intelligence, he couldn't imagine that more than 20 years ago, who could see today, and at that time, he had already begun to implement that plan.

Chess player!

How many chess players were there inside the Manchu Qing Dynasty?

Now Gao Shiqi is very curious about this answer, but he knows that he has no answer, and even if the King of Jin has told him that the internal chess players in the Manchu Qing Dynasty, he does not know their names, only their code names, at most, he only knows that they are in a high position.

Everything was deployed more than twenty years ago, and now, after more than twenty years of preparation, everything will come to an end.

Who orchestrated all of this more than twenty years ago?

Obviously, it can't be the King of Jin in front of you, who will it be?

Gao Shiqi thought of His Majesty the Emperor, who had a one-sided relationship, perhaps, only him, only he would implement such a long plan.

Perhaps, in addition to the Manchus, there were also chess players in other places.

Chess player!

It took more than 20 years for those chess players to go from chess pieces to chess players. In this game, the chess pieces are different from the chess players, the chess pieces are always discardable, and the chess players are the ones who play the game.

What role have those players played over the past 20 years? Perhaps, in the past, he didn't know, but now, through the recent period of understanding, he can at least be sure that there were chess players in the upper echelons of the Manchu Qing Dynasty, otherwise, the King of Jin would not have told him those things.

The indecipherable intelligence is not important, because through that "chess player", the Ming Dynasty already knew the plans of the Manchu Qing Dynasty, and their plan was to come to the Western Expeditionary Army, and they wanted to encircle the Western Expeditionary Army in exchange for the compromise of the Ming Dynasty.

The Manchus' wishful thinking was good, but they had thought that their plan had been obtained by the Ming Dynasty, and they made another plan along the way, so that hundreds of thousands of Qing troops would fall into the net.

Thinking of the plan formulated by the Governor's Office of the Five Armies, Gao Shiqi believed that once the plan was implemented, the Manchus would completely disappear from this world, at most, the previous Jiannu who surrendered, and they could still survive in the world, as for Jingnan......

Eventually, everything here will be wiped out!

Turning around, Li Dingguo looked at Gao Shiqi, he was holding a pipe in his hand, this pipe was given to him by His Majesty, sometimes, His Majesty likes to reward some inconspicuous gadgets, looking at him, Li Dingguo did not speak, but just silently finished smoking the tobacco in the pipe, and then walked to the table, looked at the intelligence file, and then said.

"Well, do you think we should approve their plan, or do it ourselves?"

The information in the city is very simple, after a long period of preparation, the plan to burn the grain depot can already be implemented, and everything is ready only to the east wind. As soon as it is approved outside the city, it will be implemented when the weather is right.

"I feel that if necessary, it should be up to us to do it, after all, the siege war is just beginning, whether it is a chess player or a chess piece, it will still be useful in the coming days, everyone, may play an unexpected role, if it is set on fire in the city, then it is very likely to lead to the exposure of chess pieces, and may even lead to the exposure of chess players. We have to be cautious about this, after all, we don't know the harm it can cause. ”

Gao Shiqi's reminder made Li Dingguo nod and said.

"That's true, if we let the dark line in the city set fire, Jiannu will definitely conduct a large-scale inventory, and there will definitely be our people exposed at that time, which is really not a good thing for us, but if we do it, I'm afraid it won't be easy!"

It is certainly not an easy task to set fire to the granary inside the city from outside the city.

"The range of our rockets is only more than 3 miles, and this distance is definitely not within reach."

Naturally, Li Dingguo thought of the rockets that have not been widely used to use the balance rod, the range of which is less than four miles, compared with artillery shells, its warhead has explosive warheads, and there are also incendiary bombs made of nalotment, which are extremely powerful and suitable for arson. However, its accuracy is very poor, but if it is used to attack the city, such a large city is not so accurate, but it will kill a lot of ordinary people, but how many ordinary people are here?

It's all Jiannu!

"Rockets?"

Gao Shiqi shook his head and said.

"It definitely won't work with rockets, the range is too close, our front line is too far from the city, we can consider using other things."

"Anything else?"

Li Dingguo looked at Gao Shiqi and was a little curious about his thoughts. After looking at him for a while, Li Dingguo smiled.

"Why, without rockets, is there anything else?"

Do you have any other good stuff in your hands? How come I, the commander of the Western Expeditionary Army, don't know?

"Big five, actually, that's really a good thing!"

Gao Shiqi replied with a smile:

"It's just that no one has thought of using it like this in the past, my lord, actually, we can give it a try."

Late that night, the curtain was gloomy, and there was a dead silence between heaven and earth. Compared to the past, the wind seems to be a little stronger today, and it is blowing from the southeast.

"It's so windy tonight!"

Feeling the wind in the air, Li Deyun, who was standing on the earthen wall outside Jingnan City, yawned lazily.

The wind was indeed much stronger than usual tonight, and although it was already spring and the ice and snow had already melted, the wind still made people feel a little chilly. The wind blew and he couldn't help but shrink his head.

"It's too cold this day......"

"But no, Uncle Li, you say, what's the use of us staying here all day? The Ming army is more than ten miles away, and that ......"

"But no, it's so far away, you have to come over, and you have to shoot a cannon for half a day before you can come over, isn't it......"

"Come on, one by one, let's just do it, the adults will do whatever they want......"

A few city guards, you said it word by word, and Li Deyun also felt a little tired. He also knows that he is on this city wall, which is nothing more than a scene, as for the use, it will definitely not be sent now, first, there will be no Ming army to attack the city, as for the second, that is, someone wants to escape from the city, spend a dozen taels of silver, and can swagger out of the city gate.

"No matter what, you have to finish this shift, don't you? Ah......h

As he spoke, Li Deyun yawned and squinted at the night sky, there are so many stars in the sky......

Just when he was thinking about whether to lean against the wall and squint for a while, he looked at the stars and moon in the sky, and suddenly wondered.

"What's that?"

In the night, several bright shadows were coming this way.

"What?"

The people at the head of the city followed him and looked into the air.

"Oh my God...... That's, that'......"

"Well, it's not the moon!"

"The moon in your house has five ...... Six! ”

"That's, big, big lantern?"

"Don't say it, that color is really a bit similar!"

It's a bit like a big lantern indeed!

Although he had never seen anything in the air, in Li Deyun's opinion, the thing that floated along the wind was indeed like a big lantern.

"Well, that's too high......"

Even if it is far away, Li Deyun can still feel its size, it is very large, it can even be said to be very large, it floats from the air, and the whole exudes orange light, like a lantern on the house of adults, but they are floating in the air.

Very high!

It's a full one or two hundred feet!

It could even be higher.

"My God, this, this must be more than one or two hundred zhang high, what is this, why is it in ......the sky?"

The Qing army on the city wall did not know that these six big lanterns were actually hot air balloons, as early as more than ten years ago, Qinghe Academy made a hot air balloon that could carry people according to the principle of Kong Ming lantern, but because of its limited use, it has been only used for performances, until a few years ago, the army began to use hot air balloons for reconnaissance - hot air balloons can fly into the air, condescending to reconfront the interior of the city, although this purpose can also be achieved by setting up high grounds, etc., but there are no hot air balloons to use flexibly, on the battlefield, A condescending hot air balloon can alert a radius of tens of miles.

In many exercises, the use of hot air balloons, with the help of this function, dozens of miles away when the enemy began to move, has completed the deployment, and then to wait for the hard work of the enemy, but also because of the excellent performance of the hot air balloon, will be quickly accepted by the Ming army, this western expedition is the first time that the hot air balloon into the battlefield, but because the Qing army has no courage to sneak attack, so it has not come in handy.

No one thought that the hot air balloon, which was only used for warning in the past, could come in another use - to fly the hot air balloon into the sky, and then float to Jingnan City with the wind, and then drop incendiary bombs into the city and burn the grain depot in the city!

The idea was the brainchild of Gao Shiqi, even though he was not a career officer. Marching and fighting wars is also not his specialty. But he still saw a whole new way of fighting from hot air balloons.

He believes that if the potential of these hot air balloons is fully exploited. The way of war is bound to be fundamentally changed. That's why he made this suggestion. Use a hot air balloon to attack the grain depot inside the city. This is a new attempt.

When the Qing army at the head of the city was unknown, Zhao Lingyun, who was on the hot air balloon, was staring at the ground, looking for a target - in the silent midnight, a few clusters of flames were particularly eye-catching in the dark Jingnan City.

"There!"

Pointing to the target on the ground, Zhao Lingyun looked a little anxious.

"Captain, we're on the wrong side! I'll do the math, and by the time we fly over, we'll have to be at least a hundred fathoms away! What to do? ”

"What to do? Raise it up and the air flow above is different! ”

Zhao Lingyun shouted loudly.

In his command, the team members increased the fuel injectors to heat up the hot air balloon, and the only thing they could control on the hot air balloon was the altitude. Heating can be raised and cooling can be reduced. Then, the direction can be controlled according to the wind flow at different heights, and it can also be adjusted according to the size and angle of the hot air balloon's rope and the balloon's upper mouth.

This is because the air is layered, for example, 300-500 fathoms (meters) above the ground blows the south wind, and 600-800 fathoms blows the north wind. If you want to go south, it is in the wind layer of 300-500 fathoms, and if you go north, it will rise.

"Pay attention to the ...... of investigating the drawstring"

With the efforts of Zhao Lingyun and his comrades-in-arms, the hot air balloon finally flew towards the location of the grain depot indicated by the flames on the ground, which was indeed a test for these balloon soldiers who were usually accustomed to quietly observing targets in the air. It's also a new attempt.

This attempt is extremely important for these balloonmen who did not play a role in the war, and they hope to play their part in the war and get their share of merit.

However, it is not easy to fly the balloon above the target at night, and even after several experiments before they go, they still face a lot of problems when they try to control the course of the hot air balloon, after all, most of the time in the past, they are only fixed there, and have never carried out such a "voyage".

Although they were a little scrambling, with the efforts of the balloonists, the balloons still slowly adjusted their course in the air and flew towards the target.

After the course has been adjusted. Once again, the height of their hot air balloon was lowered. When the balloon approaches the target. The balloonists in the hot air balloons stared at their targets on the ground.

When is the best time to drop bombs?

Everyone is not sure about this, although they have conducted tests before, however, everyone knows that the difference in wind speed, the difference in altitude, directly affects the accuracy of bombing.

If the wind is strong, if the distance is too high. Perhaps the dropped bomb simply will not hit the target.

Although they know this. But there is no way to control everything. At least there's nothing good to do. That's why. When approaching the target, Zhao Lingyun ordered his comrades.

"Lower the height."

Then he added,

"The lower we fly, the higher the accuracy of the bomb drop, and strive to finish the job in one trip."

After saying this, his eyes were fixed on the ground, staring at Jingnan City, which was a black hole on the ground......
