Li Yu was telling Gao Shi about Minzhuang's work tasks, and Li Huaixian in the warehouse ran out.

"Your Highness, wait."

“？”

"Your Highness, do you need a pharmacist to follow you when you use gunpowder?"

"What? And the pharmacist? ”

"Exactly."

Li Huaixian stood still and said, "Your Highness, we have our own pharmacists in Nanyang, but there are not many of them, only seven. ”

"A pharmacist who makes gunpowder?"

"yes."

"Hey, do we still have this baby? Get them quickly. ”

Li Huaixian arranged for someone to find a pharmacist, and Gao Shi took Wei Ai to lead Minzhuang.

The effort was not great, Wei Ai brought five hundred strong young men with black pressure.

"Get the gunpowder out first."

With an order, a hundred large altars one meter high were lifted out.

At this time, the sun is shining, and there is no wind or rain.

The jars were placed in the shade of a tree, and the lids were opened to allow them to breathe.

After moving these, Wei Ai and Gao Shi took these people to carry grain and grass again.

As soon as they left, Li Huaixian hurriedly brought seven people.

Li Yu took a look, I'll go.

These seven people are like the seven monsters in Jiangnan, they are different in height, shortness, fat and thinness, and one of them is still old-fashioned.

"Your Highness, this is our pharmacist."

"Uh, good, good!"

As soon as the seven people heard that this was King De and this was Nanyang's God, they immediately knelt down and kowtowed.

"You're pharmacists?"

"Yes."

The old Taoist priest replied.

"Will you be the fuse, then?"

"Uh, what's the fuse?"

When Li Yu heard this, they didn't understand! Also, people today don't know the power of gunpowder explosions.

"Come, you all learn from me, and you have to do it yourself in the future."

Li Yu asked the guards to remove the armor on his body, and he breathed a sigh of relief, and this time he took off more than ten or twenty catties of weight, and immediately became much lighter.

"Let's all go get your gear ready."

Most of the guards had returned, and they had to sharpen their lances and knives, check for arrows, and so on, leaving only a group of guards with them.

When the seven old Taoist priests saw King De saying that they would learn from him, they were all very curious, and the prince would also get gunpowder?

"Li Huaixian, find some linen cloth and hemp rope."

It didn't take much effort, and everything I prepared was ready.

Everyone is surrounding Li Yu, wanting to open their eyes, what kind of fame does King De want to make?

Li Yu first cut a piece of linen cloth with scissors, scooped out a spoonful of gunpowder from the jar with a wooden spoon, and sprinkled it evenly on the strips of cloth.

Then the strips of cloth are rolled up to the thickness of chopsticks, and tightly wrapped around the outside with thin hemp rope, so that a simple fuse is completed.

"Come on, let's go out and test it."

Everyone came out on the street and formed a circle.

The guards were very consciously on guard outside the circle, and the eyes of the seven old Taoist priests were straight.

"Ignition."

"Hehe, Your Highness, I'll come."

As soon as the old Taoist priest flicked the sleeves of his robe, two more flints came out of his hand.

Bang Bang Bang ~~~

Hit the flint three times nearby, and the spark flashed, instantly igniting the gunpowder in the fuse.

I saw the fuse made of the linen, sneering and spewing green smoke, and the sparks rushed forward in the linen, and the gunpowder was all burned, and the linen cloth also burned.

Looking at the ashes on the ground, the old Taoist priest grinned, turned his head and asked, "Your Highness, what is this fuse for?" ”

"This is a fuse used to ignite gunpowder, and if it is ignited at a long distance, people will have time to evacuate, and it is safe."

"Oh."

The old Taoist priest swallowed his saliva and said, "Your Highness, this is very similar to our Fire Dao!" ”

"Fire Road? What is Fire Path? ”

"Why don't I show it to His Highness?"

"Okay, you demonstrate."

As soon as the other pharmacists heard that they were going to demonstrate the fire path, they consciously began to act separately.

Soon, each of them brought a spoonful of gunpowder, and on the side of the street they scattered a twisted brown line of gunpowder on the ground, and at the end there was a small pile of gunpowder noodles on which dry grass and dead wood were placed.

Seeing that it was over, the old Taoist priest struck a few times with a flint, and the spark instantly ignited the gunpowder strip, and the sneering gunpowder burned out instantly, and with a bang, the hay at the end was ignited, and the dead wood also burned.

"Uh......"

Seeing the operation of these pharmacists, Li Yu felt that the ancients were so smart, they only used the simplest way to achieve their goals, and they underestimated the ancients!

"Good, good, good!"

"Each person will be rewarded twice, follow us tonight."

Although Li Yu knows that this fire path has great limitations, it is enough for now, and as for the fuse or something, take your time in the future.

That night, when the people were feasted on the war meal, five hundred people drove fifty chariots, pulling gunpowder, grain, grass, and tools, and set out.

Their destination was Bowangpo, ten miles northeast of Nanyang.

Bowangpo is located in Xiangcheng, Fangcheng to Nanyang must pass way, there is water in the west, there is blocked water in the east, Bowangpo is between the two waters, here is the place where Zhuge Kongming used soldiers.

On the moon land, Li Yuguan looked here, the hills were undulating, the sides were slow slopes, and in the middle was a winding passage.

It seems that tomorrow these mountain bandits will go this way.

"Let's do it, dig a pit in the middle of the road, big enough to bury gunpowder jars in it, and each jar is ten feet apart."

Five hundred people threw off their arms to dig a pit, dug one, and the old Taoist priest buried one, but first covered the jar tightly, the dew was heavy at night, and he was afraid of the tide.

The guards were not idle on the hillside, picking up their heads and planing, which was digging trenches.

The distance from the top of the slope to the bottom of the slope is about 100 meters, and the height difference is about 50 meters, so it is very comfortable to put arrows on it.

Minzhuang dug a total of 90 pits, and the strength of the people was great, and it was completed in two hours.

In order to increase the success rate, Li Yu asked them to dig seven half-man-high deep ditches from the top of the slope to the bottom of the slope, a distance of 20 zhang from the gunpowder jar at the bottom of the ditch.

From here, a small shallow ditch of ten centimeters was dug leading to the gunpowder jar, and there were ninety such shallow ditches, which were connected to the seven deep ditches.

After these things were done, it was already in the second half of the night, and everyone drove the carriage to the outside of Bowangpo, unloaded the cart and tied the horses, and the people and men rested on the spot.

It was getting dark, the fire was cooking, and everyone was eating and drinking and waiting for the damned bandits.

"Report, lord, the silver sand thief has appeared ten miles away."

"Revisit."

"Quick, you pharmacists hurry up and lay the fire path."

"Yes."

In fact, they have long understood that they are all old drivers and smart.

Under Li Yu's guidance, they first spread two layers of dry linen cloth in the shallow ditch, and evenly sprinkled the gunpowder on the linen cloth, which extended to the mouth of the gunpowder jar, where they also deliberately made a bunch of gunpowder, just to produce a deflagration effect, these gunpowder were covered with hay, hidden, all of them were skilled workers, and the work was quickly completed.

The pharmacists are lying in the deep ditch, they don't have to look at the situation at the bottom of the ditch, they only look at the signal on the top of the slope, as long as the signal comes, they will ignite.

At this time, the sun is high, and the morning humidity has long since dissipated.

Hidden on the top of the slope are ninety samurai who are waiting for their lives.

"Report, lord, the silver sand thief has come in."

"Okay, you guys go into hiding."

A moment later, three horses galloped from the bottom of the slope.

It wasn't until I got out of Bowang Slope and looked around at the exit that I didn't find any ambush, so I left two people here to watch, and one ran into the ditch.

Fortunately, in the morning, Li Yu asked the Minzhuang to evacuate five miles back and hide in other ditches, otherwise they would be in trouble.

Li Yu on the top of the slope was also very nervous, he was worried that these people would come up to the slope to check, so that he would be discovered.

Good thing they didn't.

While pondering, a rumbling team of horses rushed over.

Li Yu peeked at these knights, dressed in armor and holding a horse lance, each of which was more than five meters long, I go, this is still a mountain bandit? Why don't I believe it? This is obviously the army!

The horses were getting in more and more, at least four or five hundred, but there were not many people, there were two or three hundred, and soon they came under Li Yu's nose.

At this moment he saw clearly that it was indeed two horses, one on horseback, and the other on a large bag of small things, which at first glance was robbed, and one of the horses had a woman tied to its back.

The front team of the horse team has already come to the second half of Bowangpo, and it will be too late to do it at this time.

Suddenly, a small flag appeared on the top of the slope and waved it three times below.

The old Taoist priest couldn't wait any longer, and the vibration of the horse's hooves trampling made him extremely nervous.

Finally saw a signal from the top of the slope, for a while he still couldn't believe it, rubbed his eyes to confirm, and then got up and hit the fire path in the shallow ditch and started the flint.

The horse team at the bottom of the ditch did not pay any attention to the changes on the hillside, and the sun was shining at this time, and everyone was lazy.

Yesterday, they grabbed a pass around Xiangcheng, and then rested ten miles away, and had breakfast this morning, and then lazily came to Nanyang, Nanyang is much richer than Xiangcheng.

I heard the general say that as long as they come to Dengzhou to eat in spring and autumn, they can destroy their cultivation and harvest, and in a few years, this place will be our territory.

This time it was Vice General Yang who led the team, and it was the bearded man.

Vice General Yang is not an ordinary person, he is the cousin of Yang Shihou of the Silver Spear Festival, a person with a bright future!

At this time, Vice General Yang suddenly grabbed the reins of the horse, and the whole team slowly stopped.

Halfway up the mountainside, puffs of green smoke rose and quickly came to the bottom of the slope, accompanied by a sneering sound.

"Huh? What's going on? Check it out. ”

His own soldiers jumped off their horses and ran to the place where the smoke was rising.

Li Yu saw this scene at the top of the slope, and his heart suddenly hung up.

To be discovered?

Suddenly, there was silence between heaven and earth.

Then the earth shook and the mountains shook.

The neighing of the war horse at the bottom of the ditch, and the BMW of Vice General Yang stood up.

Thundered~~~~

An earth-shattering explosion was like thunder on dry land.

In Li Yu's eyes, he saw a flash of fire at the bottom of the slope, a black mushroom cloud rose, a thunder shook the heavens and the earth, the soil in the trenches fell down, and all the guards opened their mouths wide, looking directly at the scene that destroyed the world and the earth.
