"Bang dong, bang dong..."

At the quarry more than three miles away from Jinguan City, the sound of iron and stone colliding could be heard constantly.

Someone held an iron rod in his hand and kept pushing it down.

As they continued to exert force, a hole was gradually dug out in the connected stone slab.

Some water was poured into the cave, and as everyone moved, mud mixed with stone foam came out of the cave entrance and flowed around.

At this time, half of the length of the 1.5-meter-long iron bar had not penetrated into the stone slab, but the three people holding the iron bar still had no intention of stopping. They still held the iron bar and lifted it up, and then fiercely

Use it down hard.

The so-called habit is an action, which is to hold the iron bar and pound it down hard.

However, when the iron bar is about to reach the bottom of the stone slab, suddenly exert force to push the iron bar down in your hand. At the same time, release your hands holding the iron bar and let the iron bar fall by itself.

This way, your arms and hands won't be shocked.

And the effect is much better than holding the iron bar with your hands and pounding it directly under the stone slab without letting go.

There is no doubt that doing such a thing is not simple or easy at all.

It is a job that requires a lot of effort.

After these three people got used to it for a while, they were so tired that they didn't have much energy anymore.

Seeing this, people who were waiting on the side immediately came over to take over and continue doing this.

The few people who had been replaced came to the side, drank some cold water, and rested. While watching the three people who had done their work for themselves and others, they imagined the Son of God and themselves and others.

The scene I mentioned.

I want to see the result of this matter as soon as possible.

What they were looking forward to was naturally what Han Cheng said about using gunpowder to explode rocks.

In fact, not only them, but Han Cheng, who was the first to tell these things in the tribe and who immediately promoted the progress of this matter after experimenting with the effects of gunpowder, is also looking forward to seeing this matter.

result.

After all, this was the first time he personally directed people in the tribe to do this.

In the past, I only saw adults operating it.

Han Cheng had seen similar things happen twice.

One time was when I was digging a well at home when I was a child, and I used explosives to jump down and knock the unmovable rocks.

In addition, people in the village blasted stones to build houses.

At that time, many people were reluctant to spend money to buy too many bricks when building houses, so they mainly used free-of-charge stones.

It is true that stones are free of charge, but if you want to get these stones, you have to pay something like effort.

So these rocks need to be exploded by yourself.

Han Cheng, who caught the tail end of that era, was lucky enough to see how people in the village blasted the stones used to build houses in Gangshan.

The method is the same as what is going on in the tribe.

Just use this method first to make a hole in the big stone slab.

As for pouring water into the stone holes being drilled, the main purpose is to allow the pounded stone powder to rise out of the stone holes along with the water.

Otherwise, with these stone powders around, if the hole is drilled too deep, it won’t be able to be drilled...

These are things that many people get after many attempts.

Now Han Cheng, who was lucky enough to watch the excitement once, carried it directly, which saved a lot of effort.

Amidst the continuous 'bang-dong' sounds, the stone hole was drilled deeper and deeper, and finally only less than thirty centimeters remained outside before Han Cheng, the Son of God, called to stop.

Then, under the command of Han Cheng, the Son of God, everyone used tattered rags wrapped on sticks to thoroughly clean the stone hole.

It won't work if you don't clean it, especially if there is no water in it.

Otherwise, if gunpowder gets inside, part of the gunpowder will get damp, which will affect the power of the gunpowder.

After everyone was busy, Han Cheng came over with a jar of gunpowder that he had prepared himself, and then pointed the jar down toward the mouth of the stone hole.

The gunpowder turned into a line and flowed downwards along the edge of the jar, and soon most of the jar's gunpowder was gone.

When Han Cheng saw this, he stopped and brought over a cannon that was much thicker than before, as thick as a chopstick, and inserted it into the stone hole, which was more than half filled with gunpowder.

among.

Of course, before doing this, Han Cheng first used a relatively thin wooden stick to poke down the stone hole for a while, so that the gunpowder poured into the stone hole became more solid.

As for this longer and thicker version of the gun twister, or the fuse, Han Cheng made it after a lot of thinking. There is even a layer wrapped inside and outside the thing.

Layer of linen.

The performance is certainly not as good as the mature fuses of later generations.

However, after Han Cheng spent a lot of thought on it, what he called the fuse was much more effective than the cannon twist he had made before!

As for the tricks he had done before, he wouldn't dare to apply them to this.

The people in the tribe are still a little afraid of something like gunpowder that can erupt with such a sound, so when Han Cheng was doing these things, many people stood far away and did not dare to do it.

Come closer.

Even those who stood around and watched Han Cheng do these things at close range were more or less on tenterhooks.

As for the two who had carried Han Cheng back twice, their duties were similar to that of guards. At this time, they were staring unblinkingly at Han Cheng's movements and the stone hole.

When any movement came, the Son of God immediately protected him, and prepared to take the Son of God out of danger immediately.

Even if it was just a misunderstanding from before, we would still do whatever it takes.

Han Cheng felt this state of being in the tribe to some extent, but he didn't feel anything about it.

Because this is a very normal reaction.

People in the tribe have little contact with gunpowder and their understanding of gunpowder is not deep enough.

As time goes by, and people in the tribe have more contact with each other, and get used to the existence of these things, they will gradually get better.

But in the final analysis, it is good for most people to have a certain degree of reverence for this thing. After all, things like gunpowder can easily transform into deadly existences that take people's lives at certain times, so they should not be taken lightly.

Under everyone's nervous gaze, Han Cheng continued to move. After placing the fuse, he poured gunpowder into the stone hole.

Han Cheng waited until the gunpowder was about ten centimeters away from the edge of the stone hole before he stopped pouring the gunpowder inside.

After putting the jar aside, pick up the stick and pound it back and forth for a while, and the gunpowder will go down about two centimeters.

After going down, he poured some more gunpowder into it and then stopped.

Then use a round piece of paper with some oiliness and a hole in the middle to pass it through the fuse in the middle, then roll it all the way into the stone hole, then stretch it flat and tighten it.

It sticks tightly to the gunpowder.

After doing this, all that needs to be done is to seal the hole.

In order to allow the gunpowder to explode successfully and ensure that the explosion is powerful, it is very demanding to seal the hole.

One of the biggest requirements is that the hole must be sealed tightly!

Otherwise, embarrassing things like big flowers are very likely to happen.

It's just that this is a stone hole. Naturally, it cannot be driven with nails and sealed with surrounding stones like a cannon.

However, Han Cheng, who had watched the entire process, naturally knew this method.

And he knew not just one way, but two.

One of them is to use reconciled yellow mud to seal it.

The mixed yellow mud glue can completely block the entire hole, and it is also very airtight, making it a very good and suitable material.

Another one uses mixed white mortar to fill it inside.

Of course, the white mortar cannot be mixed too thinly. If it is thin, water will seep in and a lot of gunpowder will be wetted.

However, because the white ash mortar is harder than yellow mud after solidification, the sealing effect is also better.

But the disadvantage is that it takes a long time to wait.

What Han Cheng used this time was to seal it with yellow mud.

The reason for this is that on the one hand Han Cheng wanted to see the effect as soon as possible, and on the other hand it was because Han Cheng himself was not at ease with the quality of the fuses he made.

He used white mortar with a much higher moisture content than yellow mud to seal it, and if he waited for such a long time, he was really worried that the fuse would get soaked and something embarrassing would happen that would not explode.

Han Cheng, who had a hand stained with yellow mud, used his fingers to smooth out the last bit of yellow mud at the edge of the hole, and the sealing work was completed.

Then all that needs to be done is to loosen the coiled fuse and go away into the distance.

It was the first time for Han Da Shenzi to do such a thing. For safety reasons, he actually extended the fuse an excessive thirty meters!

After doing this, Han Dashenzi nodded with satisfaction, and then asked people to cover it with wet branches that had been cut down and bundled into large bundles.

The entire holed stone slab was covered.
