"Bang, bang, bang..."

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

Someone was holding an iron rod and pushing it down continuously.

As they continued to exert force, a hole was gradually created on the stone slab.

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

At this time, half of the 1.5-meter-long iron bar had been sunk into the stone slab, but the three people holding the iron bar had no intention of stopping. They still lifted it up again and again, and then pushed 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, he suddenly exerted force to push the iron bar downwards. At the same time, he released his hands holding the iron bar and let it fall by itself.

In this way, your arms and hands will not be shaken.

And the effect is much better than holding the iron bar with your hands and pounding it directly under the stone slab.

There is no doubt that this is not simple or easy to do.

It's a job that requires a lot of effort.

After being here for a while, these three people were so tired that they had little strength left.

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

The few people who were replaced came to the side, drank some cold boiled water, and took a rest. They watched the three people who were doing the work for them, and imagined the scene that the Son of God had told them about.

I want to see the result of this matter soon.

What they were looking forward to was, of course, what Han Cheng said about using gunpowder to blast stones.

In fact, it's not just them. Even Han Cheng, who was the first to speak out about these things in the tribe and who immediately pushed this matter forward after experimenting with the effects of gunpowder, was also very much looking forward to seeing the results of this matter.

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

In the past, I had only seen adults do it.

Han Cheng had seen similar things happen twice.

Once when I was a child, my family was digging a well and they used dynamite to knock over the rocks below that could not be moved.

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

At that time, many people were reluctant to buy too many bricks when building houses, and mainly used free stones.

Stones are indeed free, but if you want to get them, you have to pay something like effort.

So these stones need to be blasted by ourselves.

Han Cheng, who caught the tail end of that era, was fortunate enough to see how the villagers blasted stones for building houses on Gangshan Mountain.

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

First use this method to make a hole on the large stone slab.

As for pouring water into the stone holes being drilled, it is mainly to allow the stone powder that has been pounded out to rise out of the stone holes along with the water.

Otherwise, with the stone powder, if the hole is too deep, it will be difficult to drill...

These are things that many people have obtained after many attempts.

Now it was directly carried over by Han Cheng, who had the honor of watching the excitement once, which saved a lot of effort.

With continuous "clang dong" sounds, the stone hole was drilled deeper and deeper, and finally only less than 30 centimeters was left outside before Han Cheng, the Son of God, called a halt.

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

It won't work if you don't clean it thoroughly, and especially be careful not to let any water get inside.

Otherwise, if the gunpowder is mixed inside, part of the gunpowder will become damp, which will affect the power of the gunpowder.

After everyone was busy for a while, Han Cheng came over personally carrying a jar of gunpowder he had prepared himself, and then lowered the jar into the mouth of the stone hole.

The gunpowder flowed down along the edge of the jar in a line, and soon most of the jar of gunpowder was gone.

Han Cheng stopped when he saw this, and took out a firecracker that was much thicker than the previous one, as thick as a chopstick, and inserted it into the stone hole that was already more than half filled with gunpowder.

Of course, before doing this, Han Cheng first used a thinner wooden stick to poke down along the stone hole for a while to make the gunpowder poured into the stone hole more solid.

As for this extended and thickened version of the fuse, or the detonator, Han Cheng made it after much thought. The inside and outside of this thing are even wrapped with a layer of linen.

Of course, its performance is not as good as the mature fuse of later generations.

However, after Han Cheng spent a lot of time and effort on it, this thing he called a fuse was much more effective than the firecracker he had made before!

As for the firecrackers he had made before, he would never dare to use them for this purpose.

The people in the tribe were still somewhat afraid of gunpowder, something that could make such a loud noise, so when Han Cheng was doing these things, many people stood far away and did not dare to come closer.

Even those who were watching Han Cheng doing these things closely were more or less worried.

As for the two who had carried Han Cheng back twice and whose duties were similar to those of guards, they were staring at Han Cheng's movements and the stone hole without blinking at this time, ready to protect the Son of God immediately if any movement was heard and take him out of danger immediately.

Even if it is just a misunderstanding like before, it is still worth it.

Han Cheng felt the situation of the people in the tribe to some extent, but he didn't think anything of it.

Because this is a very normal reaction.

The people in the tribe have little contact with gunpowder and do not have a deep understanding of it.

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

But in the final analysis, it is good that most people have a certain awe of this thing. After all, things like gunpowder can easily turn into deadly things that take lives at certain times, and should not be taken lightly.

Under the nervous gaze of the crowd, Han Cheng continued to work. After placing the fuse, he poured gunpowder into the stone hole.

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

After putting the can aside, pick up a 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 gunpowder into it before stopping.

Then use a round, oily piece of paper with a hole in the middle to pass it through the fuse in the middle, then pull it all the way into the stone hole, stretch it flat, and stick it tightly to the gunpowder.

After doing all this, all you need to do is seal the hole.

In order to allow the gunpowder to explode successfully and ensure that the explosion is powerful enough, sealing the hole requires very high standards.

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

Otherwise, there is a high possibility of embarrassing things like big petals happening.

But this is a stone hole, so it cannot be nailed in like a cannon. It can only be sealed with surrounding stones.

However, Han Cheng, who had observed the whole process, naturally knew this method best.

And he knew not just one way, but two.

One of them is to seal it with mixed yellow mud.

The mixed yellow mud glue can completely block the entire hole and has good air tightness, making it a very good and suitable material.

Another method is to pour the mixed white lime mortar into it.

Of course, the white lime slurry cannot be too thin. If it is too thin, water will seep in and wet a lot of gunpowder.

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

But the disadvantage is that you need to wait for a long time.

This time, Han Cheng used yellow mud to seal the hole.

The reason for this is that, on the one hand, Han Cheng wants to see the results sooner, and on the other hand, Han Cheng himself is worried about the quality of the fuses he made.

Using white lime mortar, which has a significantly higher water content than yellow mud, to seal it, and then waiting for such a long time, he was really worried that the fuse would get soaked, and then the embarrassing situation of not exploding would occur.

Han Cheng, with one hand stained with yellow mud, used his fingers to smooth out the last bit of yellow mud at the edge of the cave entrance, and the sealing task was completed.

Then what needs to be done is to loosen the coiled fuse one by one and fly away into the distance.

Han Dashenzi, who was doing this for the first time, extended the fuse an excessive thirty meters for safety reasons!

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

The entire stone slab with holes in it was covered.

The main purpose of doing this is to prevent the rocks from flying around and injuring people and buildings.

After a busy period, the place was finally cleaned up. Han Cheng checked it carefully again, and after confirming that nothing was missing, he began to lead his people away from here and asked the onlookers to move away. Many people evacuated the valley directly, leaving only a small number of people nearby.

Among these few people were Han Cheng, several guards, and the long-legged man who was responsible for lighting the fire and ran very fast.

Han Cheng didn't want to let Changtui do this at first, but Changtui said that if the Son of God could do such a dangerous thing personally, then why couldn't he, who was far inferior to the Son of God, start the fire?

Of course, if it were just this point, Han Cheng would naturally not agree to let Changtui do this, and would still be extremely determined to drive him to Jinguan City.

But after saying these words, didn't Changtui show off his long legs again?

After such a pair of particularly eye-catching long legs were revealed, Han Cheng finally agreed.

After all, things are just as Long Legs himself said, his pair of long legs are really an advantage!

As for something as dangerous as lighting a fire, it would be safer if someone could run very fast.

Under the watchful eyes of Han Cheng and several others who were hiding behind a bunker about 300 meters away from the place where the explosion was to be carried out, the long legs that had been determined to ignite the fire before still seemed rather nervous at this moment.

He held the fire starter in his hand and lit it several times before he finally managed to light the fuse.

After the fuse was lit, he did not stop for a moment. As if his butt was burned by fire, he jumped up from here and ran wildly towards the back without looking back during the whole process.

He ran to the shelter that he had built about 150 meters away from the place where the fire started, bent down and hid himself. Only then did he feel at ease.

Two eyes appeared from behind the thick cover and looked towards the place where the fire had just been ignited. They saw that the abnormal fuse was only burned about a little more than half at this time.

Seeing this, Changtui couldn't help but feel relieved. If he had known it would be like this, he would not have run so hard and so fast.

"boom!"

As Changtui was thinking with regret and Han Cheng was waiting anxiously, the fuse burned out and drilled into the stone hole.

Then a loud explosion suddenly sounded here!

The sound was extremely loud, just like the loudest thunder in summer suddenly exploding above your head!

So much so that there are continuous echoes!

For a moment, the whole place was filled with this continuous sound, which kept ringing and rumbling!

Apart from this sound, there was no other sound in the entire place.

As the sound rang out, the large bundle of wet branches with leaves covering the middle position was actually lifted up to a height of nearly two meters before falling down!

In the midst of the smoke, some stones could be vaguely seen breaking through the bundles of firewood and rushing out!

Seeing this scene, everyone present was so shocked that they were speechless for a moment!

The long legs that had been running so fast just now, now I felt that the long legs that I was so proud of were shaking uncontrollably...

Even Han Cheng was equally excited.

After a while of excited silence, Han Cheng was the first to break the silence and stood up, stroking the cover with one hand.

"Come on, follow me and take a look!"

Han Cheng stood up and said this, his voice couldn't help but tremble a little...
