I am Wu Dalang, starting with Pan Jinlian

Wu Fei began to explain: "To tell you the truth, fireworks are not as powerful as imagined. This time, the Liao army can be hit hard this time, and the victory lies in surprise!"

Yang Yanzhao showed an attitude of listening attentively.

Wu Fei paused for a moment, and continued: "In the future, when the Liao army gets used to fireworks, this thing will basically be useless!"

"Then is there something more powerful that can replace fireworks?"

"What? I want to do it!" Wu Fei fell into deep thought.

To say that the fireworks are useless, Wu Fei himself doesn't believe it. The erupting power can hurt people without any problem, but it can only hurt people.

If you want to achieve a greater effect, it is estimated that there is no possibility.

As for the gunpowder in the fireworks, this thing can be made out.

Wu Fei remembered that the general formula of gunpowder was very simple, that is, saltpeter, charcoal and sulfur in a certain proportion.

He probably remembered that the ratio of the three should be 75%, 15% and 15%.

As for how to make it yourself in the future, it should also be determined according to the purity of the raw materials of the three.

The only thing Wu Fei is not sure about is whether there is saltpeter and sulfur in Da Song. If there is, everything is simple, and the rest is how to purify.

If not, he has more things to do, look for two kinds of ore, and then prepare them.

Thinking of this, Wu Fei retreated left and right.

Then, he continued to say to Yang Yanzhao: "Although fireworks are not very useful, the ingredients in them, what I call gunpowder, are still very useful!"

"Gunpowder? What is that?" Yang Yanzhao asked suspiciously.

"Uh, gunpowder, it's gunpowder!" Wu Fei felt that his whole body was not well, and the more he explained, the more troublesome it became.

"Forget it, I'll take apart the fireworks and show you what gunpowder is!"

After speaking, based on the principle of speaking with facts, Wu Fei asked someone to bring a firework.

With fireworks in his hand, Wu Fei took out a small knife, cut open the nine small fireworks packaged together, and took out one of them.

Then he took the fireworks and carefully peeled off the outer paper.

The internal structure of the fireworks is so clearly presented in front of the eyes.

There is some mud on the top and bottom, several powders of different colors in the middle, and a thread-like thing that connects to the outside.

Wu Fei pointed to these powders and told Yang Yanzhao that these were gunpowder!
Only then did Yang Yanzhao suddenly realize.

"After defeating the Liao army and returning to Kaifeng, I will donate the formula of gunpowder, and then find a way to make gunpowder! At that time, I can use gunpowder to make some weapons. If the Liao army comes again, it will not only be It's so easy to get hurt!"

Hearing this, Yang Yanzhao stopped.

He called the guards in and reconfirmed that the Liao army should not come again. After Wu Fei greeted him, he went to sleep on his own.

As for Yang Yanzhao, he went out to patrol around, arranged for the guards on the city wall, and then returned to his residence, and fell asleep with his clothes on.

The cavalry of the Liao army, who were still in shock, returned to the camp in twos and threes, and finally counted and found that only two-thirds of them came back.

But these returning cavalry, their eyes are evasive, showing a look of fear from time to time.

General Bu Luhua on the right looked very embarrassed, he knelt and climbed into Yelvjing's handsome tent.

"General, I failed, please punish me!"

Yelvjing was taken aback. He remembered that when Buluhua led the army to go out, Buluhua's morale was very high, and he patted his chest and said that he would definitely win Daizhou City.

But, why did Bu Luhua become like this after such a short hour?

Just now, Yelvjing stood outside the handsome tent and watched from a distance for a while.

He vaguely saw explosions and clusters of lights coming from the city of Daizhou, but he really didn't know what happened.

Seeing the appearance of Buluhua and the appearance of those cavalrymen who came back, Yelvjing knew that these people were temporarily useless, at least for this night.

Even if they were ordered to go to Daicheng again, they probably would not dare to go.

Yelvjing was very disappointed, he looked at the time, it was almost dawn.

Therefore, he felt that there was no need to arrange for people to attack Daicheng this night.

As for other things, let's wait until dawn!

But before that, there are still things that should be asked.

"Buluhua, what's going on? Tell me the details!" Yelvjing asked.

"This!" Bu Luhua was stunned, he didn't know how to talk about it!

He didn't know what the white lights flying from the city wall were!

What is even more unbelievable is that the white light exploded after flying to the camp of the Liao army. Although it looks colorful, it is very beautiful!
But the damage caused is so real.

Seeing the dumbfounded Buluhua, Yelvjing felt very tired!
"Buluhua, hurry up!"

Bu Luhua was awakened, and then told the whole process of the incident.

At the beginning, everything went smoothly. Bu Luhua led his subordinates and tiptoed towards the city wall of Daizhou City.

But just when he thought that he could win Daizhou City this time, an accident happened!
They touched the warning device arranged by Song Jun!

Then, it's their nightmare time!
Those streaks of white light coming fast, and the beautiful colorful colors, caused the defeat of the Liao army!

After listening to Buluhua's description, Yelvjing still didn't understand what that thing was!
"Okay, let's all go down! Wait until dawn!"

Yelvjing threw down a word and drove everyone out.

Although he wanted to sleep very much, but he suffered an inexplicable defeat, so he couldn't sleep no matter what.

In the end, Yelvjing simply didn't sleep anymore, just sat like that, waiting for the dawn.

In Daizhou City, Yang Yanzhao got up as soon as the sky was lighted, and he sent people out of the city to start cleaning the battlefield.

On the battlefield, there were some corpses of the Liao army lying in disorder, as well as the corpses of some horses.

According to past practice, the heads of these Liao army corpses must be chopped off, which is a proof of military merit.

In addition to the heads of the Liao army, the other valuables are the corpses of horses.

These horse carcasses, of course, will be left behind. When there is a food shortage, they can still be used as food.

But other things are basically useless.

However, in order to prevent possible epidemics, Yang Yanzhao ordered that the corpses of the Liao army be collected, piled up in a big pit, and set alight.

Of course, it still has to be buried in the end.

Thanks to Wu Fei, the battle to defend the city last night ended in a complete victory for the Song army.

This is mainly due to the unexpected discharge of fireworks!
Compared with Yang Yanzhao and other soldiers of the Song Army, although Wu Fei was also very happy to win the battle, his mood was not so beautiful!
Five or six hundred fireworks were consumed for several rounds of fireworks last night.

And these fireworks all have a price. Fortunately, the fireworks were directly taken out by Wu Fei from the system, and he only paid the cost price.

From this incident, Wu Fei understood the truth that war is a game of fighting for money.

He didn't understand this sentence very well before, but now, he understands it.

Last night, in a short period of time, the hundreds of fireworks he took out were all set off like this. Isn't this just money?
When Wu Fei woke up and went up the city wall, he wanted to see the battlefield.

But unfortunately, the battlefield has been cleaned up!

Only black dust and pools of blood were left on the ground.

As for the corpse, it was gone!

The only other visible thing was a fire not far away, and the fire was burning. From such a distance, he could still smell the stench.

Wu Fei knew that this was burning the corpse!
He could feel the mood of the Liao army under the city last night, it was a feeling of despair.

In the dark, I was already terrified, and was attacked by unknown things.

What made the Liao army even more desperate was that they could only be beaten, but they could not hit the enemy. From time to time, some people were overturned to the ground by startled horses, and then trampled by other startled horses, so that they died of serious injuries.
