On the mountain, Song Xiance looked down at the bottom of the mountain, Jinan City in the distance, only twenty miles away from them, in front of Song Xiance, he rushed out of thirteen hot air balloons overnight according to the drawings drawn by Cao Bianjiao, with a fine mantle as an air bag, a bamboo basket as a support point, what the effect is, it is not known, behind him, are twenty-six people in the army who volunteered to die.

"Soldiers, you are the heroes of my Ming Dynasty, this thing is created by the general, I don't know whether it can succeed or not, how to operate, I have already told you, the next can only rely on you, you may die, but whether it is successful or not, your family will receive a generous pension, your name will be engraved in the martyr's garden, you don't have to worry, if you succeed, each person will be rewarded with fifty silver dollars, ready to ......"

"I am willing to die for the country!" The twenty-six strong men all had a resolute face, they already knew their possible end, but no one was afraid, they were willing to do this because they received Cao Bianjiao's great kindness, and they wanted to repay the favor, so they were willing to dedicate themselves to the great cause of the Northern Expedition.

"Good! Ready to go! ”

Under Song Xiance's greeting, a group of two people stepped into the hanging basket, the brazier on the hanging basket has also been lit, the pine resin inside is burning fiercely, and the soldiers who are preparing outside have already used a long bamboo pole to provoke a stroll, so that the heat continues to fill it.

After a stick of incense, the first burning hot air balloon began to climb, slowly rising into the air, everyone was holding their breath, looking at this scene, not daring to be careless, still maintaining the action in their hands, watching the air bag get bigger and bigger, not long after, the first hot air balloon climbed more than a foot high, no need for bamboo poles to help support.

Before the hour, Cao Bianjiao appeared outside the city with his men and horses, but until this moment, a whole hour passed, but the Ming army did not move at all, even Fei Yangwu was full of doubts, what did the Ming army want to do, the siege was in a hurry, what was standing outside the city like this, he himself felt bored.

"Bei Ziye, I heard that Cao Bianjiao is cunning with soldiers, will there be any conspiracy?" Lu Fengchun also came to the top of the city pass, and when he saw that the Ming army outside the city had not moved, he was also puzzled.

Fei Yangwu sneered, looked outside the city, and said: "No matter what conspiracy they have, anyway, I just can't hold out, they bombarded with artillery a few days ago to no avail, I think they can still have any means, just wait for the arrival of imperial reinforcements, and then it will be their end......"

"Huh...... What is that...... What is that......" Just as Fei Yangwu was talking to Lu Fengchun, there was a commotion among the soldiers above the city, and many people were looking up at the sky, not knowing where their clothes came from, wandering in the air, it was very strange, they had never seen such a thing.

"It's like a Kong Ming lantern, no, it's not a Kong Ming lantern......" Some of the soldiers began to talk to each other, full of doubts, what was the sudden appearance in the sky.

"Governor Lu, what the hell do you think that's that?" Fei Yangwu also saw something getting closer and closer in the sky, and he was very puzzled, what could float in the air, he had never thought about it.

Lu Fengchun also shook his head, frowned and said: "I've never seen it, it's not a Kong Ming lantern, Kong Ming Lantern is not so big......"

At this time, the rumbling sound of drums sounded outside the city, and the Ming army began to attack the city, and the thirty red-clothed cannons that had already been placed outside the city were about to start bombarding again.

"Quick, dodge the artillery attack, ...... quickly," Fei Yangwu also shouted.

In the sky, a hot air balloon has floated above the city of Jinan, about twenty or thirty zhang away from the city pass, you can see the underground situation clearly, and the next person is also waving the flag in his hand on it.

"General, signal ......" Ma Wannian, who was beside Cao Bianjiao, also pointed to the hot air balloon in the sky and shouted.

Cao Bianjiao looked at it intently, and after a while, he also ordered: "The artillery men listen to the order, the southwest of the city is the place where the enemy's ordnance warehouse is located, give me a ......."

"Bang bang bang bang...... thirty red-coated cannons, one after another, began to attack, all bombarding in one direction, which was the signal sent by the flag soldiers on the hot air balloon.

The cannonballs fell on the city in the city, and suddenly there were fireworks and fireworks, and four cannonballs landed in the southwest corner of the city accurately, where Fei Yangwu gathered ordnance, and most of the ordnance needed for defense was piled there.

"Death squad, prepare!" Cao Bianjiao immediately issued another military order.

When even a thousand people stood up, each of them was not wearing armor, but wearing a wet robe, as if they had been drenched in water, and there were still dripping water on their bodies.

"Throwing ......" hot air balloons, when they came to the top, they immediately threw down a dozen or so small cans loaded in the hanging baskets, and almost all of them landed on the top of the city.

"It's kerosene... It's kerosene...... Oh no..."Someone immediately smelled the familiar smell and exclaimed.

Each hot air balloon was filled with twenty small jars, each jar contained a pound of fire oil, and the thirteen hot air balloons, except for the two that had an accident when they were drifting, the remaining eleven were all dropped their contents, and they also randomly rose higher.

"Shoot them down for me, release arrows, and guns......" Fei Yangwu also immediately commanded his soldiers to attack those floating hot air balloons, and he couldn't sit back and watch them go on like this, the defenses in the city were all in the eyes of the enemy, and they still had any secrets to speak of.

But the hot air balloon has risen and floated away, their arrows and muskets are facing the sky, they can't reach it at all, they can only be in vain, but Cao Bianjiao's side has started to attack again, thirty red-clothed cannons, fired at the same time, this time Cao Bianjiao is no longer using a burst bomb, but a new type of *, the old-fashioned cannonball is hollowed out, filled with pine resin, when the cannonball is launched, there will be no explosion, but a small fragment explodes, and the pine resin inside will be ignited by the lead and flow out, acting as a fireball.

But it was this fireball that ignited the fire oil flowing above the city, and it was immediately a fire that spread rapidly, burning half of the city wall.

"Chong ......" saw the fire above the city, a thousand death squads also roared and rushed up with a cloud ladder, the Qing army above the city head was busy fighting the fire, or dodging the fire and burning, who still has the heart to organize resistance, even if they have the heart, they are blocked by the fire, they are also powerless!

The unhindered Ming army death squad rushed to the city, the scorching flames above the city did not make them flinch, and they immediately threw out the fire pot they carried, so that the fire spread more widely, but they rushed forward without hesitation, because they were wet, and there was no fire to burn their bodies, they all rushed out of the fire circle, rushed into the panicked Qing army, and began a fierce massacre.

It was a massacre, because the Qing army's position had been in chaos, and the formation was dispersed by the fire, and the Ming army that rushed up was not afraid of death, they did not dare to resist closely, they were afraid of them, they all retreated, many green battalion soldiers turned around directly, and Fei Yangwu had already run to the city to hide, and no one commanded them to fight back, they could only flee in a hurry, and then were ruthlessly killed to the ground.
