"Everyone, stop what you're doing, I have something to say." Shu Han returned to the tunnel, everyone is working hard, since it is worth two shifts, there is no rest time in the middle, naturally it is only able to work hard in the first shift, if you do a good job, you can save about ten minutes for everyone to rest, although for heavy physical labor, ten minutes, is not a rest at all, but it is better than nothing, it is better than continuous rotation.

Hearing Shu Han's words, everyone stopped, Shu Han's departure was more than thirty minutes, everyone was obviously curious, what was he going to do, Shu Han saw that everyone looked at him, so he said: "I thought of a way last night, it may be possible to improve the efficiency of our mining, just now I went to someone to borrow some tools, let's try it now, if it can really improve efficiency, we will do it according to my method, what do you think?" ”

Everyone's eyes were a little surprised, and Shi Ping stepped forward and asked, "Chief, what is the new method?" He was also shocked in his heart, he originally thought that the reason why Shu Han left the team was to go to Wang Lie to intercede, after all, although there were profits in front of the two shifts, it was still too dangerous, and if he was not careful, it would be the end of the mass grave, and Shi Ping also thought that Shu Han's approach was in his heart.

So when Shu Han was about to leave, he didn't stop him, but he didn't expect Shu Han to borrow something, which he didn't expect.

"You come with me." Shu Han didn't say much, whether this method can be successful, it depends on whether it can be effective at the moment, Shu Han took the lead and walked to the front of the team, in front of which is the working face, the uneven ore is densely covered at the top of the tunnel in front of him, after Shu Han stood still, he turned around and said to everyone:

"Yesterday when we were mining, I don't know if you felt it, that is, the efficiency of our mining is very slow, in fact, I have been wondering, is there a better way to improve the efficiency of mining, just yesterday, I came up with a way, you see.."

Several other people were a little unimpressed, this mining work has lasted for hundreds of years, everyone is digging ore with iron picks, there is no other way, Shu Han is a child, can come up with a way? They didn't believe it at all, but because Shu Han was the head of the dormitory, everyone didn't directly refute it.

It was Zhu Ze, perhaps because of his young age, and because he had been with Shu Han for the past few days, he trusted Shu Han quite a lot, he didn't do it like others, but asked: "Brother Shu Han, what do you think, say it and let everyone hear it, and everyone can also help you take a look." ”

Shu Han looked at Zhu Ze gratefully, and then told everyone what he had planned yesterday, that is, to mine according to the shallow hole retention method of coal mines, and the specific measure was to insert a nail into the ore, and then hit the surrounding area with a hammer, so that the nail would drive the surrounding stones to split.

Then insert three to five long nails around it, expand the gaps around it, and then pull out the long nails, use thicker nails, and then drill holes in it, after several cycles, the iron ore will appear a circle of cracks, at this time with a shovel to dig, you can easily knock the ore down from the working face.

This method is actually not commonly used in modern times, even if there is, it is also used to drill holes by machine, but even if it is manual, Shu Han thinks that it is easier to knock it directly than using an iron pickaxe so directly, this method seems to be extremely simple, to put it bluntly, it is to fix the force at one point, so as to break the surface with a point, but if it is not written in the data, Shu Han will not think of using this method at all.

It's just that Shu Han doesn't dare to guarantee that this set of methods can really be done, after all, coal mines and iron mines are very different, and at the same time, this world is also very different from modern times, and the quality of ore is also a big problem, which will affect the success of the experiment, and others do not believe it, so Shu Han said:

"I don't know if this method can be successful, let's try it first, if we can, then our future work can be easier, what do you think?"

Shu Han's words made everyone fall into silence, they never thought that there would be such a way of mining, when they first heard it, they thought that it was impossible to succeed, but after Shu Han explained it in detail, although many people were still in the clouds, Shi Ping and Zhang Song felt that it was really possible to improve efficiency.

"Well, I agree with the head of the house, it's nothing to try anyway, if you fail, it's a big deal to follow the old way, Zhang Song, you come and help me, let's try it first."

Shi Ping is the tallest and strongest embryo among the people present, his words are also representative, and the others no longer pick thorns when they see this, and Shi Ping took the hammer from Shu Han's hand, after all, everyone present, except for him, really no one has the strength to insert a nail into the iron ore.

These iron ores are much harder than coal, and other people's figures of more than one meter and six are afraid that they can be killed at once, Shi Ping picked up the hammer, and Zhang Song followed Shu Han's instructions to put the nails in a suitable position to ensure that the long nails would not be bent or deviated from the direction due to the beating of Shi Ping.

The others looked at it seriously, Shi Ping picked up the hammer and tried it back and forth twice to prevent frustration and hurt his waist, the mine was not as good as the outside, and his body gave him more strength than others, which naturally made him difficult to move in the narrow mine, wielding a sledgehammer, and he also needed to pay great attention.

After waving a few times and getting used to the inertia and weight of the hammer, Shi Ping began to hit the nails according to Shu Han's instructions one by one, and the sound of 'ding ding ding' kept echoing in the tunnel, so loud that Zhu Ze and the others couldn't help but cover their ears, Shu Han saw this, tore off a piece of the medical bandage that he had replaced from his waist, and handed it to everyone, so that everyone could stuff it into their ears and use it as earplugs to avoid too much blow to their ears.

“80，80，80”

The thrilling scene, Shu Han on the side couldn't help but wander to the famous sketch in his previous life, and the corners of his mouth couldn't help but show a smile, and at this time, the corners of other people's mouths also bloomed a beautiful chrysanthemum, they didn't think of this famous sketch, but under the strength of Shiping, a miracle really happened in front of their eyes.

Layers of cracks, spread on the surface of the stone, it only took about 20 minutes, the entire force surface under the action of the iron nail, covered with a large number of cracks, Shiping raised the shovel to the working surface to hit hard, the original rock-solid iron stone but like a clod of sand solidified, fell a little, others hurriedly picked up, a basket was filled in a short time.

"This, this speed, it's fast enough."

Shi Ping wiped the sweat on his head with his hands, looking at the results of his work, his eyes were full of shock, he didn't understand why a few iron nails could cause such a result, and looked at Shu Han with great doubts in his eyes.

Although these slaves are different from the slaves in ancient history textbooks, they have received the most basic education, especially people like Shi Ping, who are very intelligent.

But this kind of education only stayed at literacy, two hundred years, a large number of people died, so that human civilization has been broken, in the city of iron and stone, according to the understanding of memory, is in a state of joint rule of theocracy and aristocracy, as for science, has long been submerged under layers of rubble.

Otherwise, it would not be until now, even the generator has not been manufactured, in memory, there is only one small power plant in the entire Iron and Stone City, which was left before the end of civilization, and after two hundred years of operation, most of the generator coils have long been dilapidated, and only two sets are still in use, which can only supply the most core area of Iron and Stone City, which is the current level of science and technology.

The level of science and technology is still so, the level of science, not to mention, according to the memory of the original owner, is Newton's three major theorems, which are things that no one knows in Ironstone City, and it is conceivable that there is no thinking about the area and direction of the force.

They may have seen the entry of a thing to change a part, for example, hitting the ground with a hammer, it will form a layer of cracks in the ground, not just a pit, or for example, if you beat the glass with your hand, the glass will be broken completely, not only the place in your hand, this is the problem of material structure, they may often see such scenes in daily life, but how to apply these things to work and production, but they don't know anything.

That's why miners are still mining in the most primitive way, instead of coming up with new ways to change the status quo like Shuhan, not because they don't want to, but because they don't think about it.

"Brother Shu Han, how did you come up with this method, this is too good." Zhu Ze on the side said.

"It's nothing, just think about it, I often see that when it snows, people sweep the ice off the eaves, often by hitting it hard, so that the ice breaks, so I want to see if this method can work, I didn't expect it to work, everyone go on."

Shu Han naturally thought of an excuse a long time ago, and when he said this, others only thought that Shu Han was smart, and he didn't have any doubts in his heart.

"Hey, I didn't think of that." Zhu Ze touched his head and said.

"If you can think of it, then you should be the head of this dormitory." Zhang Song said with a smile on the side, he originally thought that the task was extremely difficult to complete, but now everything is no longer a problem, and his mood is very good.
