"Boom boom, boom boom..."

　　 At the quarry more than three miles away from Jinguan City, the sound of iron and stone collisions kept ringing.

　　 Someone is holding an iron rod in his hand and is constantly going down.

　　 With their continuous exertion, a hole was gradually pounded out of the stone slabs that were connected together.

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

At this time, half of the length of the one-meter-five long iron bar has been submerged in the stone slab, but the three people holding the iron bar still did not intend to stop. They still held the iron bar and lifted it once and then again. Get used to ruthlessly.

　　The so-called habituation is a kind of action, that is, holding an iron bar and pushing down hard.

　　 But when the iron bar was about to reach the bottom of the stone slab, I suddenly exerted force to smash the iron bar in his hand, and at the same time, loosen the hands holding the iron bar and let the iron bar fall by itself.

　　 In this case, you won’t be shocked to your arms and hands.

　　 And the effect is much better than smashing directly under the stone slab without letting go.

　　 There is no doubt that such things are not simple and easy to do.

　　 is a job that requires a lot of energy.

　　 After these three people have been used here for a while, they are tired and have little energy.

　　 Seeing this, there were people who stopped waiting and came over to replace them, and then came to do this thing.

And these few of them who were replaced came to one side, drank some cold water, took a rest, while watching these three people working on behalf of themselves and others, and imagined the son of God and himself and others. The kind of scene I said.

　　 I want to see the result of this event soon.

　　 What they said they expected was naturally what Han Cheng said about blasting rocks with gunpowder.

In fact, it’s not just them, even Han Cheng, who was the first to say these things in the tribe, and after experimenting with the effects of gunpowder, who immediately pushed the matter forward, is also very much looking forward to seeing this. result.

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

　　 Before, I only saw adults operate it.

　　 There are two similar things that Han Cheng has seen.

　　 Once when I was a kid, I dig a well in my house, and I used explosives to hit the immovable stone underneath.

　　 The other is the people in Murakami blowing up rocks to build houses.

　　 At that time, many people built houses, but they couldn't afford to buy too many bricks, and they were mainly based on unpaid stones.

　　 The stones really don’t require money, but if you want to get these stones, you have to pay for things such as strength.

　　 So these stones need to be fried by themselves.

　　 Han Cheng, who caught the tail of that era, was fortunate enough to have seen how people in the village exploded the stones used to build houses in Gangshan.

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

　　 is to use this method first to make holes in the stone slabs.

　　 As for pouring water into the stone hole that is being punched, it is mainly for the stone powder that is pounded out to rise with the water from the stone hole that is used to it.

　　 Otherwise, with these stone powders, the holes will be drilled deep, and they won’t move...

　　 These are things that many people get after many attempts.

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

　　 Amid the continuous sound of ‘bang bang’, the stone hole was punched deeper and deeper. In the end, only less than 30 centimeters remained outside before the **** son Han Cheng stopped.

　　 Then, under the command of the **** son Han Cheng, everyone used the rags wrapped on the stick to completely clean the stone hole.

　　 It’s impossible if you don’t clean it up, especially be careful not to let water in it.

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

　　 After everyone was busy, Han Cheng personally carried a can of gunpowder that he had prepared himself, and then moved the can down to the mouth of the stone hole.

　　 The gunpowder followed the edge of the jar, turning into a line and flowing down, and soon most of the gunpowder in the jar went down.

Seeing this, Han Cheng stopped his hand, and twisted a cannon that was much thicker than before, and was thick enough for chopsticks, and inserted it into a stone hole that was more than half filled with gunpowder. Among.

　　 Of course, before doing this, Han Cheng first used a thinner wooden stick and stabbed it down the stone hole for a while, so that the gunpowder poured into the stone hole became more porcelain.

As for this long and thick version of the gunner, or the fuse, Han Cheng made it by hand after careful consideration. The inside and the outer layer of this thing are even wrapped. Layer of burlap.

　　The performance is of course not as good as the fuse that has developed and matured in later generations.

　　 But after Han Cheng has spent a lot of thoughtful treatment, what he called the fuse, the effect is much stronger than the gun twist he made before!

　　 Regarding the artillery pieces he had done before, he dare not apply them to this.

People in the tribe still have some fear for things like gunpowder that can erupt with such a sound. So when Han Cheng was doing these things, many people stood far away and didn't dare. Come closer.

　　 Even those who are leaning around and observing Han Cheng doing these things up close are more or less worried.

As for the two who have ran back with Han Cheng twice, their duties are similar to those of guards. At this time, they stared at Han Cheng unblinkingly, as well as the stone hole. Whenever something happens, the Son of God immediately protects him, and prepares for the Son of God to escape danger immediately.

　　 Even if it was a misunderstanding from the previous time, it is the same.

　　 The state of the people in the tribe Han Cheng felt more or less, but he didn't feel anything about it.

　　Because this is a normal reaction.

　　 People in the tribe have little contact with gunpowder, and they don't have a deep understanding of gunpowder.

　　 When time is up, people in the tribe will come into contact with many people. After getting used to the existence of these things, it will be better.

　　 But in the final analysis, it is good for most people to have a certain amount of awe for this thing. After all, things like gunpowder can easily be transformed into life-killing existences at some point, and 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 less than ten centimeters away from the edge of the stone hole of the tribe before Han Cheng stopped pouring the medicine inside.

　　 After putting the jar aside, I picked up the stick and pounded it back and forth for a while, and the gunpowder went down almost two centimeters.

After 　　 went down, he poured some gunpowder into it before he stopped.

Then use a round piece of paper with some oiliness and a hole in the middle, put it on the fuse in the middle, and then push it all the way into the stone hole, and then stretch it flat and tighten it. Close to the gunpowder.

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

　　 In order to be able to successfully explode these gunpowder, and to ensure that the explosive power is not small, the hole is very demanding to be blocked.

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

　　 Otherwise, it is very likely that there will be an embarrassing thing like Da Ba Hua.

　　 It's just that this is a stone hole. Naturally, you can't use nails to drive it like a roll gun and seal it with surrounding stones.

　　 However, Han Cheng, who has observed the whole journey the most, knows this method.

　　 And the way he knows is not just one, but two.

　　 One of them is to use reconciled yellow mud to block.

　　 and good yellow clay glue, can completely block the entire hole, and the air tightness is also very good, it is a very good and suitable material.

　　 The other is to pour it with a white mortar made up.

　　Of course, the white mortar is also too thin to be mixed. If it is thin, the water will seep and it will wet a lot of gunpowder.

　　 But because the white ash mortar is harder than the yellow mud after it has solidified, the sealing effect is better.

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

　　 What Han Cheng used this time was to use yellow mud to block it.

　　The reason for this is that on the one hand, Han Cheng wants to see the effect early, and on the other hand, because Han Cheng himself is uneasy about the quality of the fuse he has made.

　　 used white mortar with a water content significantly larger than that of yellow mud to seal it. After waiting for such a long time, he was really worried that the fuse would be soaked and embarrassing things that would not blow up.

　　 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 hole, and this time the great cause of sealing was completed.

　　 Then all that needs to be done is to loosen the fuse coiled into a disc and move away.

　　 The **** son Han Da who did this kind of thing for the first time, out of safety considerations, actually directly extended the fuse to an excessive 30 meters!

　　 After finishing this, Han Da Shenzi nodded in satisfaction, and then asked people to cover the wet branches that had been cut down and bundled into large bundles.

　　 covered the whole slab with holes.

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

After a busy period of time, this place was finally fixed. Han Cheng carefully checked again and confirmed that there was nothing missing, and then began to take people away from here, causing the onlookers to retreat far away. Many people They all evacuated the valley directly, leaving only a small number of people nearby.

　　 Among these few people are Han Cheng, a few guards, and long legs who are responsible for the ignition and running very fast.

At the beginning, Han Cheng didn’t want to let Long Legs do this thing, but Long Legs said that the son of God can do this dangerous thing himself, so why not someone who is far inferior to the son of God. Can it be fired?

　　 Of course, if it was just this, Han Cheng would naturally not agree to long legs to do this, and he would still be extremely determined to rush it to Jinguan City.

　　 But after saying these words, the long legs revealed their long legs again?

　　 After revealing such a pair of particularly conspicuous long legs, Han Cheng finally agreed.

　　 After all, things are just like Long Legs himself said, his long legs are really advantageous!

　　 And for a dangerous thing like ignition, you need someone who runs very fast to be safer.

After Han Cheng and a few people were hiding in the place where they were about to explode, watching from a bunker a full 300 meters away, they made up their minds to set fire to the long legs without hesitation. At this time, they seemed quite nervous. .

　　 He held a fire-starter in his hand and lit it several times before it was regarded as igniting the fuse.

　　 After the fuse was ignited, he didn't stop for a moment, as if he had been burned to the bottom by fire. From here, he rushed towards the back in a rush, without turning his head back in the whole process.

　　 ran all the way to the place where the ignition was, almost one hundred and five meters away, behind the bunker built, bent down and hid, only then did he settle down.

　　 Two eyes were exposed behind the thick bunker and looked towards the place where the fire had just been fired. Only the super-normal fuse was only burned at this time.

　　 Seeing this, my long legs couldn't help but feel determined. I knew it was like this a long time ago. I didn't run like this just now. I just ran so fast.

　　 "Boom!"

　　In the long-legged thoughts ~lightnovelpub.net~While Han Cheng was waiting nervously, the fuse burned out and got into the stone hole.

　　 Then there was a sudden explosion!

　　'S voice is exceptionally loud, like the loudest thunder in summer bursting overhead!

　　 so much so that there is a continuous echo!

　　 Suddenly, this whole place is the continuous sound, constantly ringing, the sound rumbling!

　　 Except for this sound, there is no other sound in the whole place.

　　 With the sound of this sound, the large bundle of wet branches with leaves covering the middle position was actually lifted up to a distance of almost two meters before it fell!

　　 In the smoke of gunpowder, some rocks could vaguely break through the shackles of the firewood bundles and rush out from the inside!

　　 All the people present who watched such a scene suddenly lost their voices in shock!

　　 The long and fast legs that just ran. At this time, I only feel that my long legs, which I am proud of, are shaking uncontrollably...

　　 Even if it was Han Cheng, he was still very excited.

　　 stayed in such excitement and silence for a while, Han Cheng was the first to break the silence and stood up with one hand touching the bunker.

　　 "Go, come with me and take a look!"

　　 Han Cheng stood up and said this aloud, his voice trembling a little...
