Following Han Cheng's order and the action of standing up and heading towards the explosion site, those people who were completely shocked by the noise of the mining finally woke up, came out of that state, stood up from behind the bunker, and moved with the Son of God.

It’s just that the walking postures of many people seemed particularly strange. A group of strong men felt weak in their steps at this time, and many of them couldn’t help but have their legs trembling slightly.

The scene just now and the deafening sound were really too shocking!

A group of people who walked in a strange manner came to a place filled with the smell of gunpowder.

After arriving here, one can see more directly the devastation here and the power displayed by the shocking explosion just now.

Under Han Cheng's command, the people who came over removed the bundles of branches covering the place, and the situation here immediately appeared in front of everyone.

I saw that the originally extremely hard stone now had several cracks around it, with the explosion hole as the center!

One of the openings even extended as far as five or six meters!

The place where Han Cheng dug a hole and put gunpowder in was blown into a pile of rubble with a diameter of about one meter!

Looking at this scene before their eyes, everyone present was shocked and shaken!

The scene before their eyes was completely beyond their understanding!

This is definitely not something that can be done by human power.

Even though they had mastered the method of burning the stones with fire and then pouring water on them to crack them due to thermal expansion and contraction, they still could not control themselves after seeing this scene.

Because this method can only burn the stone and make it crack at best. It is really impossible to produce such an amazing effect directly like this!

However, now, this seems to be something that cannot be accomplished by human power at all, but it was completed in full view of everyone!

In the past, under the guidance of the Son of God and through what he taught them, they realized time and time again the enormous potential of human beings, the greatness of human beings, and felt that people in this state were already exceptionally powerful and great.

But now, looking at everything in front of them, and the buzzing sound that seemed to continue ringing in their ears, everyone present could not help but be shocked in their hearts, and their whole bodies were filled with another kind of shock.

This kind of shock is to once again discover the greatness and power of human beings!

Moreover, this greatness and power is so violent that it is simply subversive!

"Hiss~"

After this silence lasted for a long time, some of the people present, who were deeply shocked, finally took a deep breath subconsciously.

After this person took a breath of cold air, someone here couldn't help but follow suit and took a breath of cold air.

For a moment, there was a sound of shower running.

Except for Han Cheng, the son of God of the Qingque tribe, everyone else, without exception, couldn't help but gasp.

“God, Son of God, this, this…”

His long legs were still shaking slightly. He looked at Han Cheng with excitement, agitation, and some shock, and wanted to say something to express his feelings at the moment.

However, after opening my mouth, I found that I couldn't say anything at all...

However, Han Cheng, who was stopped by him, had an intriguing expression on his face.

Of course there is joy and excitement, as well as the joy and relief after what I said and did were proven to be successful and correct.

However, when these emotions gradually eased, feelings of loss and disappointment arose.

Of course there was loss and disappointment. After all, Han Cheng had seen someone blasting rocks once before.

After the same operation, the amount of rocks blown out was much more than what was blown out by the current cannon fire from my tribe!

As far as Han Cheng could remember, it seemed that it took a whole day to transport the goods home using a four-wheeled tractor, but it still took a long time to complete the transportation!

And the farthest piece of rock that flew was the size of a human head, and it flew almost a mile away!

There is no harm without comparison.

After such a comparison, it would be strange if Han Cheng felt relieved after clearly understanding the huge gap between the two.

"Alas~"

After thinking about it for a while, Han Cheng couldn't help but sigh.

The people who heard Han Cheng sighing couldn't help but feel confused for a moment.

Now, his tribe has obtained such an exceptionally good thing, which can greatly prove the strength, ability, and greatness of human beings. Shouldn’t they be very happy?

Why did the Son of God look so happy at this time? And even sighed?

"Son of God, why are you sighing?"

The man with long legs standing next to him couldn't help but ask the question in his mind.

Han Cheng was feeling very lost at the time, and the people around him were all from the tribe, so he didn't hide anything and spoke his mind directly.

"Compared to what I thought before, the power of gunpowder and other things is much smaller, so I felt a little disappointed for a while."

After hearing Han Cheng say this, Changtui or others pricked up their ears after hearing Changtui's question, wanting to hear why the Son of God felt in a bad mood at this time. Everyone around was stunned for a moment!

To them, these words heard from the Son of God were even more shocking than the horrifying scene before their eyes!

This scene before their eyes has already stunned and astonished everyone, they are filled with excitement and feel unprecedentedly the power and greatness of human beings.

However, now, the thing that shocked and amazed him and others to such an extent, and which could be called a miracle, was actually a failure in the eyes of the Son of God?

Far from what he expected?

The Son of God feels lost and in a bad mood because of this?

Moreover, the loss of the Son of God really existed, and it was not faked...

Faced with such a situation, how could Changtui and others remain calm?

Of course, at this moment, only Han Cheng, the Son of God, would say something like this to cause such a reaction from the people present. If someone else came and said something like this, the people present would have to exercise their fists and feet to make this person, whose brain seemed to be not working well, sober up and face the reality, and stop saying pretentious words here to attract attention...

The moon was bright and the stars were sparse. Although he didn't see the birds flying south, Han Cheng still couldn't fall asleep.

In the room, he opened his eyes, full of thought.

There is no doubt that at this time he was still thinking about the fact that he blasted rocks during the day, but the gunpowder was too weak and the result was not ideal.

If you really think about it, Han Cheng can easily think of some problems.

For example, the gunpowder made by hand is not as powerful as the gunpowder made by Murakami in later generations using fertilizers such as ammonium nitrate and sulfur.

For example, in later generations, when the villagers used the prepared gunpowder to blast rocks, they used detonators in conjunction with the gunpowder.

Han Cheng obviously doesn't have any high-end items like detonators.

With these two conditions in place, it seems reasonable for such a situation to occur during the day.

But Han Cheng still felt dissatisfied. He thought that even if the current conditions were used to blast rocks, the current situation would not occur...

Quantitative change leads to qualitative change. When the quantity accumulates to a certain level, it can trigger qualitative change.

The things that he had recited more than once in high school politics class flooded into Han Cheng's mind.

He didn't care much about it at first, but soon he couldn't help but have an idea and grabbed this thing in a flash.

yes!

Quantitative change leads to qualitative change!

The standard ratio of gunpowder requires slow research, and things like detonators are also not something that can be achieved overnight.

But before that, you can achieve the results you want through accumulation of quantity!

If one can of gunpowder doesn't work, use two cans! If two cans of gunpowder don't work, use three cans!

Under such circumstances, I don’t believe that the desired effect will not be achieved!

Han Cheng was thinking this fiercely in his heart, and suddenly his mind became clear!

But this cheerfulness did not last long, and was covered by new things again.

The thing is how to load such a large amount of gunpowder.

The most obvious, direct and simple way is to drill deeper and thicker the holes on the stone slab.

After deepening and thickening, the amount of gunpowder that can be loaded inside will naturally increase.

But such an approach is naturally difficult.

The first is the difficulty of tools.

The iron bar used during the day is already the largest in Jinguan City. If you want a bigger one, you need to go to the Tieshan residential area to customize it and have it specially cast.

This back and forth takes quite a bit of time.

Another aspect is the operational difficulty.

Now when the tribe uses an iron bar of this scale to drill holes, in order to maintain efficiency, nine people are needed to be divided into three shifts to take turns to operate. If they get a large iron bar that is twice as long and twice as thick, wouldn't a group of eighteen people be needed to operate it?

If three groups take turns, wouldn't that require fifty-four people?

Moreover, these fifty-four people have to be strong and sturdy men!

If you calculate it this way, how much manpower cost will be needed?

With so many people, even if they don't use gunpowder and just use ordinary means, the amount of ore produced will not necessarily be less than the stone produced by blasting with gunpowder in this situation.

It was because of this that Han Cheng sighed and put the matter aside after some thought.

However, after thinking for a long time, Han Cheng couldn't think of a suitable way to do this except this extremely uneconomical method, which was really a headache...

Nothing happened that night. The next day, Han Cheng got up, packed up, and after dinner, he once again led his men to the quarry outside Jinguan City.

Following Han Cheng's instructions, the place soon became busy and lively.

The nine people who participated in drilling holes in the stone yesterday found a new place and continued drilling holes in the stone.

The tool used is still the iron bar used yesterday, and the method is also the same as yesterday. However, Han Cheng knows that if he continues in this way, the effect that can be achieved will be the same as yesterday. There is no progress or breakthrough, but he is still watching with great interest from the side.

After watching for a while and seeing that everyone was making good progress, he went to the side to deal with gunpowder.

After continuous efforts by three groups of nine people, the hole was finally completely drilled and wiped clean when the sun was half set in the afternoon.

Apart from the different location, the rest of the place is no different from the one we played yesterday.

At this time, Han Cheng also started to carry the gunpowder cans and pour gunpowder into them.

Such a scene made Changtui and some others stunned. For a moment they did not understand what the Son of God was doing.

After all, the Son of God clearly expressed his dissatisfaction with the power of gunpowder to many people yesterday.

However, such a thing happened at this time, which is really easy to make people confused and puzzled.

However, Long Legs' doubts soon disappeared, because he quickly remembered what happened during a meal he had had before.

I don’t know what happened at that time, I had no appetite. I always felt like I couldn’t eat anything and didn’t want to eat anything.

However, when the meal was ready and I went to eat it, I ate no less than before.

The Son of God should now be in the same state as he was when he ate before. Although he said that this method was not good and could not achieve the desired effect, but when it really came to the last moment and the bowl of rice was brought to his mouth, he still felt that the rice tasted very good.

Thinking about these things here, Long Legs thought he had seen through everything, but he didn't notice that this time, Han Cheng poured less than one-fifth of the gunpowder in the pottery jar into the stone hole, then stopped pouring it in, and started to put in the fuse and sealed it with yellow mud...

"Okay, start the fire. You don't need to hide too far this time. The bunker fifty meters away will be fine."

After some operations, Han Cheng said to Changtui and others beside him.

Then he took the lead and walked towards the shelter behind.

After they hid behind the bunker, Long Legs, who stayed behind to light the fire, lit the fuse, then ran all the way to the bunker fifty meters away and stayed with Han Cheng and others.

A moment later, a muffled sound suddenly rang out.

Although it was very powerful, it was still much weaker than the earth-shattering noise yesterday.

After waiting for a while, everyone stood up at Han Cheng's signal and headed towards the place that had just been bombed...
