This kind of scene is naturally a little embarrassing, but fortunately, Zhu Youlang was a little mentally prepared, cleared his throat and said: "Maybe it's a problem with the proportion and tightness of gunpowder, let's check it again." ”

Although the first bombing did not achieve the desired effect, Zhu Youlang was not discouraged.

At least there was a certain degree of deflection of the wall, which proved that the blasting method was effective. Now it's time to maximize the effect of the explosion with limited resources.

It's a pity that Zhu Youlang is not from a chemistry background, otherwise he would definitely be able to do his best in the first time.

After confirming that the explosion was complete, the Ming soldiers jumped into the dug tunnel.

The smell of gunpowder was everywhere in the tunnel, and it was very choking.

This kind of visibility is not clear at all.

It took a lot of effort for them to get to the point of the explosion. At this moment, the coffin board has been blown away, but there is still more than half of the gunpowder left in the coffin.

Several of them worked together to drag and pull with all their strength, and finally dragged the remaining coffins out of the tunnel.

Zhu Youlang took a closer look before approaching and came to the conclusion that the explosion was incomplete.

The main reason for the incomplete explosion was the insufficient combustion of gunpowder. The reason why gunpowder is not burned sufficiently is simply that the airtightness is not enough.

It seems that the coffin made in this temporary rush is not up to standard.

In fact, this coffin blasting method does not strictly require that the airtightness must be extreme, as long as it is not exposed too much.

This is also the reason why Zhu Youlang chose the coffin.

The ancients regarded the aftermath as extremely important, and the nobles were often sealed with jade by their servants after death, which is said to have the effect of preventing the soul from escaping.

The poor people can't afford to use jade, but as long as it's not like a poor straw mat wrapped in a corpse and buried in a mass grave, a thin-skinned coffin is still needed.

The material of the coffin can be the most ordinary, but the airtightness is very particular, and there will be absolutely no air leakage everywhere.

Speaking of which, this is also a handicraft work, which tests the skills of craftsmen very much.

Naturally, the soldiers of the Ming army did not specialize in making coffins, and the technology would definitely not be in place.

So you still have to prepare some special coffins.

It's just that it's definitely not good to get a ready-made coffin at the moment, so Zhu Youlang ordered the temporary coffin to be killed after putting gunpowder into it. It's a little rougher, but it's barely up to his requirements.

Not once, do it again.

Zhu Youlang wants to win by quantity.

...

...

The moment Zhou Fan heard the loud noise, he was extremely scared in his heart. He had long heard that the army would use demon magic, and the Qing army in Chongqing was defeated in this way.

I thought that the city wall must have been blown up, but who would have wanted to take a closer look, but its wall had just shifted to a certain extent.

This level of deviation was within Zhou's acceptable range, and the soldiers did not even need to make too many adjustments to shoot at the Ming army from the battlements.

How capable do you think you are, that's all?

Zhou Fan smiled disdainfully.

I just said, "It's a fool's dream to blow up the city wall with gunpowder."

Not to mention gunpowder, even the red-coated cannons can't blast through the city walls.

The thief is desperate, and he is in a hurry to go to the doctor.

On the one hand, Zhou Fan ordered the soldiers to be on standby, and on the other hand, symbolically shot a round of arrows in the direction of the Ming army.

The purpose of this round of arrows is not to kill, but to provoke.

Aren't you angry, hit in, hit Lao Tzu?

Lao Tzu provoked me like this in the city, what can you do to me?

Zhou Fan didn't feel proud for long, and another loud bang sounded.

This one was louder than the previous one.

Although it was very sudden, it startled Zhou Fan.

But soon he burst out laughing.

It's fucking going again. It's not a poor donkey.

Zhou Fan laughed insolently, but his smile didn't last long before he froze.

Not far away, a large section of the city wall collapsed, and the adjacent walls also tilted sharply.

How did the walls suddenly blow up?

"Come on, go and block the blasted wall!"

Zhou Fan's reaction was extremely fast, and he quickly gave the order.

The walls were blown apart and were no joke. If the thieves attack from this place, the consequences are unimaginable.

The top priority is to quickly plug the gap and prevent it from becoming a breakthrough for thieves.

Under the command of Zhou Fan, the Qing soldiers swarmed to the gap and filled the gap with large blocks of stone and rolling wood.

But at this moment, the Ming army has launched a wave of offensives, and the object of the attack is naturally this gap.

Both sides are well aware of the importance of this gap, and a vicious battle is inevitable.

"Resist, resist Lao Tzu!"

For Zhou Fan, the most lacking thing now is time.

Only by withstanding the first wave of the Ming army's offensive could he repair the damaged city walls.

For this reason, he did not hesitate to mobilize heavy troops to defend this gap, and he had to defend it at all costs.

Although a gap was blown out of the city wall, the gap was not large. The rest of the walls are tilted to a certain extent.

It was much easier for the Ming soldiers to climb along the sloping city wall than along the ladder.

It's just that they also need to face the fierce resistance of the Qing soldiers.

Climb to a certain extent, and the pair is convenient to start hand-to-hand combat.

For a while, the Ming army had the advantage, and for a while, the Qing soldiers fought again.

The two sides fought for each other, and the battle entered a white heat.

Zhu Youlang, who was standing on a hill in the distance, had a full view of all this.

He cleared his throat and said in a deep voice, "The hot air balloon is ready to take off, the target is the enemy general." ”

Naturally, these words were said to Liu Xingming. After some experiments, he has basically mastered the operation method of hot air balloons.

"Yes!"

Liu Xingming was very excited at the moment.

This is in front of the three armies, and if he can make a great contribution, he will really be in the limelight.

Didn't Dad always say that he was waiting for death to eat, so he showed Dad what it means to be a dog without a gate!

Under the eyes of Zhu Youlang, Liu Xingming and several personal soldiers successively boarded the hot air balloon. A lot of earthen grenades were placed in the bamboo basket, which was the key to his decapitation operation.

However, the Son of Heaven specially instructed that the native grenade is not very stable, and it must not be stimulated, otherwise it is easy to explode.

Therefore, Liu Xingming was cautious, for fear of accidentally touching the soil grenade.

"Let's fly!"

Liu Xingming took a deep breath and swung his knife to cut the rope.

The hot air balloon slowly rises into the air, carrying the full expectations of the Son of Heaven.

Fly, fly a little higher.

The hot air balloon should naturally not be too low from the ground, otherwise it will be easy to be discovered and exploded by the Qing soldiers.

The Son of Heaven said that hot air balloons are very afraid of sharp weapons, so they must be avoided as much as possible.

But it can't be too high, otherwise the people on the ground will become black spots, and they won't be able to see who is who.

Liu Xingming doesn't want to hurt innocent people, his target is only enemy generals!

Finally, the hot air balloon rose to a height that he thought was suitable, and it happened that the wind direction was also blowing towards the city, Liu Xingming was overjoyed and said God helped me.
