I heard the screams of Jin Dajian in the bonsai.

Xu Boan hurriedly focused his attention on the bonsai in the sea of knowledge.

The next moment, all the situations in the bonsai appeared in front of Xu Bo'an.

Xu Bo'an focused his eyes on the location of the mountain temple, and saw several people who were mining stones on the cliff wall of the mountain behind the mountain temple.

Jin Dajian was surrounded in the middle, his face was pale with a lot of sweat on his head, and the undershirt around his neck was already soaked.

Looking down further, one of Jin Dajian's hands was almost completely stained red with blood, and the other hand pressed tightly against the arteries between his wrists to prevent the blood from continuing to flow out.

"Uncle Kim, right...... Sorry, I didn't mean to! A young man's face turned pale with fright, and he couldn't speak.

An older man glared at Xiao Young angrily and scolded sharply: "What nonsense, shut up!" Tell you to be careful, be careful, you kid has a dog's belly in his head. ”

Jin Dajian's face was pale, extremely ugly and twisted, one hand was tightly covering the other, and a lot of blood flowed in the ground, obviously injured.

He gritted his teeth and endured the pain and said, "Okay, don't scold him, he didn't mean it, hurry!" Huilong soup! Who is still a chick, pee up and give me here to deal with disinfection first! ”

The word Huilong soup, Xu Boan knows. Huilong soup is the boy's urine, in ancient times, people often used this thing as the boy's urine!

Of course, it is only ancient times, after all, this practice does not conform to the principles of modern medicine, and there is no scientific basis to prove that the urine of children really has therapeutic properties.

This medical knowledge was also learned by Xu Bo'an not long ago after he integrated the ancestral medical book of Dr. Zhang's family.

Seeing that Jin Dajian's palm was injured, and the injury was not light, Xu Boan was quite concerned, and his heart was a little nervous.

After all, Jin Dajian is one of the few high-end craftsmen among the people he uses, and now, he is definitely a respected senior technician, even a great craftsman!

At least among Xu Boan's followers at present, Jin Dajian does have such a status.

He had the heart to ask what the situation was, but now that Ling Feng was there, it was still a little inconvenient.

"Ling Feng, find a service area in front of you and stop for a while." Xu Boan said.

Ling Feng glanced at the mirror image on the rearview mirror, Xu Boan had already opened his eyes, it was not a dream.

The reason why Ling Feng has such doubts is really because the car has just been on the highway not long ago!

After making sure that what Mr. Xu said was not a dream, Ling Feng didn't think much about it, and immediately responded: "Okay, Mr. Xu, there is a service area more than 20 kilometers ahead, and it will take about ten minutes to get there." ”

Xu Bo'an pressed his temples, thinking about the things in the bonsai a little tiredly, and said casually: "Okay, when you get there, you can turn off the heat and go to the supermarket casually, I have a very important phone call that needs to be made." ”

"Okay, Mr. Xu!" Ling Feng replied refinedly, without saying a word.

The privacy of the leader is by no means something that a small driver can snoop on.

Soon, the car stopped smoothly in the service area, and after Ling Feng turned off the car, he carefully unplugged the car's dash cam wiring before getting out of the car.

Xu Bo'an hurriedly poked his gaze into the mountain temple.

At this moment, he was tightly tied to his wrist with a rag rope that he didn't know where to find it, which could be regarded as restricting the outflow of blood.

A young man loosened his pants and was releasing water into Kim's wound.

Obviously, this kid should be the chick they found.

Soon, the boy's urine was poured on Jin Dajian's injured palm.

As the water became stronger, the red blood stains on Jin Dajian's palm were also washed away, revealing a real wound.

A bloody wound with blurred flesh and blood, turning over the flesh on the back of the hand, and even the bones inside could be seen.

Xu Boan took a closer look and breathed a sigh of relief.

Fortunately, it didn't hurt my muscles and bones! This is also a blessing in disguise.

"Uncle Jin, shall I carry you down?" The young man said hurriedly, looking at Jin Dajian's wound worriedly.

Jin Dajian shook his head and said: "You kid is more sad than me now, and he is still nervous, and he can't go down the mountain, I'm afraid that you will lose your mind and fall down when you climb the cliff." I'll do it myself! Let's see if we can find some herbs. ”

"That's right, Brother Da Jian, I'll carry you, let's go down together. I used to work as a pharmacist in a pharmacy for a while, but I also have some simple medicine skills! ”

Jin Dajian shook his head again and said, "I really don't need to, don't go down, it's just the cool weather now, and it's the right thing to get to work." When the weather gets hotter again, the work of quarrying stones will be even more difficult. ”

Someone said worriedly: "No, Uncle Jin, your wound ...... It can't be delayed any longer, in case it affects the later recovery, this hand will be wasted. ”

Jin Dajian endured the severe pain and relieved his companions, and said: "Don't worry, when I was an apprentice before, injuries were commonplace, don't worry, I'm careful myself, it's okay, I will definitely be able to go down." ”

Someone immediately objected, saying: "This is not good, this weather has just rained, and the cliff is very smooth everywhere, you climb down the mountain with one hand, which is too dangerous." ”

Jin Dajian said: "I'm a blessed person, I really don't have to worry about me, but you, when you work next, you must be anxious to bring protective things, improve your attention and do your own protection at the same time, if I was careful just now, I will definitely be able to let go of my hand as soon as possible, in this way, when the big iron cone is smashed by him, I will definitely not be injured." ”

Not far away, on a huge stone, a neat row of iron awls was embedded in a hollow carved out of the rock.

One of the iron awls fell crookedly beside a broken hole, and a large hammer was thrown around, a cloud of bright red blood still slowly seeping into the hole.

After a brief observation, Xu Boan knew what was going on.

As a master's student majoring in civil engineering, Xu Boan naturally knows what the villains are doing.

It turned out that Jin Dajian took these little guys to mine mountain rocks, using the wedge splitting method.

Wedge splitting is a method of artificial quarrying that is often used by ancient craftsmen, and the principle is mainly to use the thrust of the splitter to split the stone.

It is said that when the Great Wall was built, craftsmen used this method to mine stones. The same is true of the stones used in the pyramids from Egypt.

Of course, these claims are largely apocryphal. But it is enough to show the practicability and wide application of this method.

To mine hard rocks with wedges, you must first use a large iron vertebrae and an iron hammer to make a row of holes in the stone.

The wedges are then embedded into the inside of the holes one by one, and then fixed on both sides of the wedges with metal sheets.

Then the wedge is struck with a hammer again, so that the hole is subjected to squeezing force and elastic deformation occurs.

When the thrust generated by the splitter is greater than the tensile strength of the rock, the rock will crack in a predetermined direction.

As the cracks around the hole grew larger and larger, until the resonance penetrated the bottom, the stone was easily split.

This method is simple, low cost, in the case of backward mechanical civilization in ancient times, this method can greatly improve the efficiency of quarrying, reduce the intensity of manual labor.

Jin Dajian's hand was an accident when he was holding the big iron spine and the little young man with a hammer to smash it.

Xiao Young missed for a while, his strength was unstable, and the hammer was directly crooked.

Knocked the big iron vertebrae back and smashed it on Jin Dajian's hand.

This is already a blessing in misfortune, at least not the sledgehammer smashed directly on Jin Dajian's palm.

Otherwise, this palm will not be saved.

As for the current situation, although it is more serious, it will not affect the recovery of the bones, in fact, it is more because of excessive bleeding, and the injury itself is quite optimistic.

At least according to Xu Boan's current ability, Jin Dajian's palm is still saved.

Thinking of this, the trace of worry about Jin Dajian in Xu Bo'an's heart eased slightly.

When it comes to treating trauma, Xu Boan has many methods.

But I have to admit that the fastest way is the incense in the mountain temple, which is incomparable!

After analyzing this, Xu Bo'an immediately flashed to the mountain temple, raised his hand to twist some incense ashes in the incense burner, and said to Jin Dajian: "Jin Dajian, I read that you have made meritorious contributions to repairing the mountain temple, and give you some good medicine." Apply this powder to the injured area and it will recover quickly. ”

While speaking, Xu Boan grabbed the void and slowly stopped the incense ash in his hand not far in front of Jin Dajian.

Because of Xu Boan's palm, these little guys can't see it.

As a result, the villains can only see a cloud of gray powder floating in the air.

When Jin Dajian heard Xu Bo'an's words, his eyes widened and he looked at the immortal medicine that suddenly appeared in front of him.

Then he shouted excitedly: "Jin Dajian thanks the mountain god grandfather for giving the elixir!" ”

As he spoke, he hurriedly knelt on the ground and kowtowed.

"Okay, you're injured, this matter is urgent, don't move around, hurry up and apply medicine." Xu Boan admonished.

Jin Dajian, who was injured in one hand, had difficulty moving, so he hurriedly ordered someone to take some incense ash and gently sprinkled it on Jin Dajian's injured palm.

The next moment, the incense ash took effect, and the miraculous effects began to show.

At first, Jin Dajian only felt a cool and numb feeling, but after a while, it turned into an itchy sensation again, as if there were small insects wriggling in the wound.

After a while, Jin Dajian's palms became very hot again, as if the feeling of being scorched in the scorching sun in the summer.

After a while, Jin Dajian suddenly discovered that the wounds that were originally like rotten flesh had actually healed!

Only a light pink scar that has just healed remains, contrasts sharply with the shriveled and yellowish skin on the side.

"Oh my God, this ...... It's also incredible. So soon there was no bloodshed? Such a big wound. ”

"What's incredible, it's an immortal medicine sent by Grandpa Mountain God himself! Elixir, do you understand! ”

"I don't understand, you know? Have you eaten? ”

"Alright, you guy is tough! If you go out to society in the future, you will definitely suffer. Come to think of it, the elixir to treat these minor ailments in the mortal world is not a small problem with holding a handle! It's not too easy, okay? ”

"Look, the wound is actually starting to heal, oh my God, it's been less than a stick of incense."

As the person concerned, Kim Dajian paid close attention to the injuries on his hands throughout the whole process.

From a bloody hole in the flesh and blood, to the current almost perfect appearance, if it is placed in normal times, it is at least a hundred days of treatment that hurts the muscles and bones.

But now, it's fully recovered?

Kim Dajian even had the illusion that he hadn't been injured!

"Thank you to the mountain god Grandpa for the gift of the elixir. Lao Jin, I don't have any skills, and I can't speak, you will see my performance in the future, and I will definitely do my best to repair your temple well! You'll be satisfied. ”

Looking at the few stones that were mined with great difficulty, Xu Boan advised: "You don't have to worry about the stone for the time being, let's get busy with other processes first." As for the stones, I'll be free for a while, and then I'll come and help. ”

When Jin Dajian heard this, he immediately said in fear: "This can't be helped, how can you do such vulgar work, how can you do such vulgar work, we will definitely be able to do it well." ”

Xu Bo'an said: "Okay, just do as I say, since it is my temple, it is naturally up to me to decide." Jin Dajian, you have a good rest first, don't exert any more effort on that injured hand in the near future, and take care of it for a while. ”

Jin Dajian piously agreed, and Xu Boan withdrew.

Xu Bo'an went to the bathroom and came back, and saw that Ling Feng was already sitting in the driver's seat waiting for Xu Bo'an.

Obviously, Ling Feng had been paying attention not far away, and as soon as Xu Bo'an got out of the car, he realized that the boss's business was over.

The car was speeding all the way, Xu Bo'an thought about it, and the stone matter still had to use the self-produced mountain stones in the bonsai.

After all, Jin Dajian and the others have already mined half of the mine, and if they don't continue to mine, this place will not be very messy.

Thinking of this, Xu Boan asked Ling Feng to drive the car directly to Dongjiang Erjian, and asked someone to send a set of electric drills to the office, and then locked the door.

Xu Bo'an opened the drill box, observed the situation of the mountain rock outside the mountain temple, and chose a suitable set of drill bits.

Then, the socket of the electric drill was connected to the plug board, and the electric drill was extended into the bonsai.

In the eyes of the little people, a huge blue-black object with a strange shape suddenly descended.

Its tip is a long black rod like black lazuli, and the long rod is covered with quite regular spiral patterns, like a kind of bloodletting blade in the military garrison of the Dajing Dynasty.

This thing is as tall as a tree, about two people hugging each other, and it shimmers in the sun.

Then, the drill bit of the electric drill slowly approached the rock wall on the cliff behind the mountain temple.

Looking at the things that suddenly appeared, the faces of the few villains who followed Jin Dajian to learn the craft were full of panic and uneasiness.

The swarthy electric drill bit was suddenly so close to him, and the sense of oppression of the villain was still quite strong.

Especially when you look up, the endless giant shape makes the villains full of awe and curiosity.

To them, this thing is like a towering mountain, impassable, yet full of mystery.

Xu Boan pressed the switch of the electric drill.

The electric drill roared, and the sound was deafening, as if even the earth was trembling. The little ones covered their ears one after another, and their faces showed painful expressions.

Only Jin Dajian looked like he was fine, his eyes were firmly fixed on the posture of the drill bit of the electric drill walking on the rocks.

As the drill rotated, huge stones were dug out. Of course, in Xu Bo'an's eyes, it was no different from soybeans, but the villains widened their eyes, looking at this scene, they all sighed with miracularity.

They began to slowly get closer, curiously looking at the magical drill bit.

Some villains even stretched out their hands and wanted to gently touch the shell of the electric drill and feel the tremor it brings.

"Don't move, it's hot!" Xu Boan spoke out in time to stop it.

The electric drill bit that has just finished work is very hot, and these little people will be able to dry it at once when they go up.

As if to confirm Xu Bo'an's words, a hare on the mountain that was so frightened that he fled in all directions because of the tremor suddenly stumbled and fell, and landed right on the electric drill bit.

The next moment, a pungent smell of burning hairs came, followed by the aroma of roasted meat, and finally the smell of burnt.

In a short period of time, the hare went through the change from burning rabbit fur to roasting rabbit to over-burning and burning.

When the drill bit cooled down a little and the temperature cooled down, Xu Boan continued to work.

He worked intently, and the cavern that the little people had dug out before grew bigger and bigger amid the rumbling sound of the electric drill.

More and more stones were beaten.

Xu Boan was estimating and asking Jin Dajian, if he had enough, he wouldn't be busy.

Just as he was about to turn off the electric drill first, suddenly, Xu Boan suddenly felt a resistance coming from the electric drill in his hand.

Then, the drill of the electric drill emitted a kind of harsh stabbing sound produced by the collision of metals. (End of chapter)
