In the following six months, Han Nuo imitated many commonly used tools, except for the lack of large construction machinery such as excavators in the mine, there were all the hand-held tools that should be there.

Han Nuo also improved the clothing of the miners, and he brought the concept of labor protection equipment into the world.

The fabric of the clothes they wore was replaced with a material similar to denim. This was developed by Han Nuo asked the Han brothers and sisters to find someone, and as soon as this fabric came out, it became a hot item. After all, whether it is used to make soldiers' armor or manual workers' uniforms, they are very suitable, both wear-resistant and cheap.

The same fabric can also be used to make gloves and shoe fabrics.

As for the miners' shoes, Hanno also introduced the concept of anti-smashing and anti-puncture, and steel plates were added to the soles and toes.

It can be said that even if a modern earthling enters this mine, he will not realize that he has crossed over, after all, the site is no different from a modern construction site except for not pulling a banner that reads "Life first, safety first".

If Han Nuo only confined the reform to this mine, it would not seem to be extraordinary. But he soon realized that the solution of this pain point might cause a wave similar to "Hufu riding and shooting" in the mortal world.

So the keen Han Nuo immediately asked the Han family brothers and sisters to unite all the gangs and businesses in Anfeng City to make and sell these labor protection supplies in their hands. At first, the gangs were not optimistic about the business, and it was not until more and more people from the sect came to buy that everyone realized that the situation was not right.

It didn't take long for Han Heming to bring back a secret letter to Han Nuo. In the secret letter, he mentioned that Wan Chamber of Commerce has set its sights on the Han family firm and is about to send someone to discuss the merger and acquisition.

After Han Nuo read the secret letter, he began to feel a little embarrassed. After all, the reforms carried out in the mine were carried out by the sect alone, but now because of his own technology, the business has fallen into a crisis.

Now he has two choices, one is to make the business name independent and join the Wan Chamber of Commerce to make himself one more backer. The other option is to report everything to the sect and ask the sect to protect the Han family. But judging from Han Nuo's experience, the scumbag's behavior will eventually be a bad death, and the result of stepping on two boats must be empty of people and money.

Therefore, he quickly decided to go back to the sect, first, to discuss with the master, and second, to talk to the sect about the in-depth development of the mine.

However, the master who "doesn't sweep a house" is really unreliable, and Elder Liu can't give any advice except to scold Han Nuo for his lack of heart, greed, and lack of pure heart. However, she still did what she could for Han Nuo, and reported the matter to the sect.

Two days later, a monk in a purple shirt suddenly appeared in the sky above the nephrite mine. The disciples who sensed its appearance immediately came out to greet him, lined up in two rows below, and stood with their heads bowed. Everyone didn't know the origin of the other party, but they only knew that even Han Nuo didn't dare to make a mistake here.

"Who is the leader disciple?" The person who came suddenly descended in front of everyone, and seeing that he was wearing a purple cloud robe, the disciples were immediately relieved.

"Disciple Zhuo Ke visits the ancestor." Zork immediately stepped forward.

"Take those tools that your Uncle Han made and show them to me." After speaking, the infant ancestor floated into the main tent of the camp.

A moment later, Zhuo Ke led people to place the tools developed by Han Nuo in front of the ancestor one by one. "This is a ground-splitting hammer, which can break the ground and break the wall; This is a diamond that pierces through the sky, which can penetrate all gold and stone; It is for the chaser of the wind, and mortals can use it to move mountains and seas; It's a ...... of mountain sawing," Zock demonstrated, one by one.

"Get me a mortal." The Ancestor ordered. After a while, Luo Jun followed Chen Zhao to the tent. "You try to get this thing in my view." Old Ancestor pointed to the tools on the ground and said to Luo Jun.

Luo Jun nodded, didn't dare to speak, and showed all the tools one by one. The old ancestor looked at it with a solemn expression, and kept brushing his long beard.

"Alright, that's it." The old ancestor stopped Luo Jun, and with an unchanged expression, he said a word to all the Qi refining disciples present, and then left abruptly.

A moment later, in the main hall at the top of Tianyun Peak, four purple-robed primordial ancestors were sitting together, and a Jindan monk was standing aside, it was Liu Yan, the refining elder. And under the main hall, there is a foundation building monk in a yellow robe, and this person is Han Nuo.

I saw a flash of light at the entrance of the main hall, and it was Elder Deng who had just arrived at the nephrite mine. Seeing him come back, another purple-robed ancestor immediately stood up. "Elder Deng, is what this son said true?"

"Elder Hao wants to know, so let's see for myself." With a wave of Elder Deng's hand, a mirror-shaped magic weapon floated in the air, which was Elder Deng's Phantom Cloud Mirror. Through the images in the phantom cloud mirror, everyone saw the picture of Luo Jun holding various tools to demonstrate.

"Use the spirit stone to provide spiritual power, press that Karakuri to drive the magic weapon, and mortals can also operate it, this thing is very well designed!" Elder Hao clapped his hands and looked at Han Nuo.

"This thing must not be made to be in the world." Another purple-robed monk also stood up, a woman named Qi Xue. "Where is the refining elder Liu Yan!"

"The disciple is here!" Elder Liu flew over to Han Nuo and stood still, bowing his head and arching his hand in reply.

"Your disciple has developed a forbidden weapon privately, are you guilty?" Although Elder Qi has a childish face, he has a temperament that is not angry and arrogant.

"Liu Yan is guilty." Elder Liu didn't explain anything.

"It's only been two and a half years since this son started, and it's only been more than a year since he succeeded in building the foundation, how can ordinary people learn such a complex alchemy technique so quickly? Master Liu Yan's nephew is nothing more than a mistake in teaching, why should Elder Qi make a big fuss. Another ancestor joined the discussion, who was only in his early twenties, with sword eyebrows and starry eyes, red lips and bright teeth.

"Elder Yun should not be partial." Elder Qi glanced at the ancestor, "As we all know, immortal cultivators are not allowed to create magic weapons that mortals can use. This junior has now violated the ban, so how can I explain it to other sects? ”

"Elder Qiqi, the disciple really didn't know that there was such a ban...... Han Nuo immediately refuted it as soon as he saw that Elder Liu was implicated.

"The erector is rude, how can you speak here!" When Elder Liu saw Han Nuo speak, he immediately refuted.

"It's okay, you let him plead." The last Yuanying elder spoke, the man had a beard, thick eyebrows and big eyes, he looked very wild, but his whole body was snow-white, and his skin seemed to be blown, it was Ye Mingsong, the second elder of Tianyunmen. Seeing him speak, the other elders all restrained a bit.

Seeing this, Han Nuo's eyes rolled, and he immediately said, "Elders, the disciple accidentally discovered that there are a large number of precious minerals buried under the nephrite mine. Now that nephrite deposits are about to be depleted, if new mines are not developed, the sect will lose a lot of income. That's why the disciple thought of using his alchemy skills to benefit the sect, but he didn't want to touch the ban by mistake. This matter was done by the disciple alone, and had nothing to do with the master. The disciples are willing to accept any punishment and ask the elders to decide. ”

"Oh?" As soon as Elder Ye heard this, he leaned forward slightly, and the rest of the elders also became serious. "What's that mine?" Elder Ye asked Han Nuo.

"Forgive the disciple for being stupid, I haven't confirmed this mineral category yet." Han Nuo shook his head. "It's just that the disciple has seen this mine in the ruins of the ancient battlefield, and it is one of the minerals at the bottom of the lake, which was discovered by the disciple by chance when he was digging a well." Han Nuo described the reason for digging the well and what he had done, but everyone was not interested, and they all talked to each other about the mine.

"As we all know, the mineral deposits in the imperial court can only be mined by mortals. All the mineral deposits that mortals cannot mine are not allowed to be excavated by any sect without permission. Elder Hao said suddenly.

"Our miners are mortal." Elder Deng spread his hands and said.

"But the tools they used are not right, if we let other sects know that we have created magic weapons that mortals can use, Tianyun Gate will be destroyed, how can a mine make up for it?" Elder Qi insisted on his own point of view.

"Elder, the tools made here are all evolved from tools held by mortals, in fact, we can use ordinary tools to mine new mines." Han Nuo arched his hand.

"Is that true?" Elder Deng came to Han Nuo with a flash of light and gave him a very small hint of wink.

"Disciples, don't dare to deceive the elders." Han Nuo introduced to everyone one by one which mortal tools those tools they saw in the Phantom Cloud Mirror, and proposed an alternative Karakuri solution that was not driven by spirit stones.

"If you were to take those mortal miners to mine that mine, would you have the confidence to dig out the veins?" Elder Ye asked quietly.

"Disciple has faith!" Hanno replied.

"You go down, and you must not leave the sect without permission." Elder Ye waved his hand and let Han Nuo leave first.

After Han Nuo came down from Tianyun Peak, he went directly to Feiyun Pavilion to wait. He waited at the door of the refining room for about half an hour before Elder Liu came back with a tired face.

"The disciple has even affected the master." As soon as Han Nuo saw Elder Liu, he immediately stepped forward and knelt on the ground.

"It's okay, it's because the teacher forgot to tell you about the taboos in the refining world." Elder Liu yawned and lazily patted Han Nuo to signal him to get up.

"The disciple doesn't understand why there is such a taboo." Han Nuo looked at Elder Liu and asked.

"How many mortals do you think there are here, how many immortal cultivators do you think?" Elder Liu looked at Han Nuo.

"There are 50,000 mortals, and there are probably hundreds of thousands of immortal cultivators." Han Nuo roughly estimated.

"If 50,000 mortals master the technique of using spirit stones to drive magic weapons, what do you think will happen to immortal cultivators in the end?" Elder Liu continued to ask.

"This ......" Han Nuo had never thought about such a question, "the immortal cultivator will eventually disappear. ”

"How so?"

"Man will always be afraid of something greater than himself, and this fear will be a reason for him to destroy the powerful. As there is a saying in my hometown, 'On the side of the couch, you will not allow others to snore.' 'If you lock a man-eating monster in the same room as a person, I'm afraid that people won't be able to sleep until they kill that monster.' Han Nuo analyzed.

"Can't get along?" Elder Liu asked with a smile on his face.

"I can't ......" Han Nuo lowered his head and thought for a while, "The fact that today's immortal forces can exist is actually due to the balance of power. Mortals, though outnumbered, are weak. And although the immortals are powerful, they are small in number because of the difficulty of cultivation. Once mortals gain greater power, this equilibrium is shattered. Not to mention whether mortals will take the initiative to challenge the immortals, even the immortals alone can't bear the power of mortals becoming stronger. ”

"Don't you understand?" Elder Liu pursed his lips and smiled, "Go back and prepare, clean up all the things that do not belong to the mortal realm, the sect is ready to submit an application to the imperial court to open a mine, and there should be an envoy to the mine to supervise and review it soon." As for the Han family's business, the elders promised that if you could mine a new mine, they would take it into the scope of protection. ”

Elder Liu also explained to Han Nuo some taboos on cultivating immortal realm refining weapons, and it was summed up that all technical applications must be dominated by immortal cultivators. Then he returned the exoskeleton armor that Han Nuo had asked him to repair, and instructed Han Nuo not to reveal his secrets easily.

And Han Nuo also understood another rule, that is, the mineral deposits in this world were not mined by immortal cultivators. Each sect can only search for mineral deposits within its own territory, and after the discovery of mineral deposits, each sect is not allowed to mine first, and must declare to the imperial court. The Imperial Court will organize a jury to the corresponding mine to ensure that the mine is fully developed and collected by mortal miners.

The main reason for this move is to avoid over-exploitation of minerals. After all, with the mining speed of an immortal cultivator, any mine can be emptied in an instant. Moreover, if rare minerals are found in mortal settlements, if they are allowed to be mined by immortal cultivators, it will cause immeasurable disasters.

The inspection team from the imperial court arrived at the mine half a month later, and Han Nuo initially thought that it was just a few civil and military generals sent by the imperial court to go through the process. After the group arrived, Han Nuo realized that he had not understood the balance of power in this world at all.

It turned out that except for one official representative of the imperial court, the rest of the people in the overseer were all elders of various sects. Two of these sects and Tianyunmen were the forces behind the royal family, while the other sects, except for the Haoran Alliance, Han Nuo didn't seem to know about them. The most important thing is that in order to show fairness, Tianyunmen did not send a single Jindan elder, and even did not increase the number of people.

"May I ask Immortal Master Han, how did you find out that there are other mineral deposits here?" The official surnamed Zhou, who represented the imperial court, held a pen in one hand and a book in the other, and asked very seriously.

"I found it while digging a well." Han Nuo pointed to the well he had dug earlier.

"Tianyunmen has been mining nephrite ore here for hundreds of years, and you only drilled a well when you came?" Elder Xu of the Haoran Alliance looked at Han Nuo with a suspicious expression.

"This ......," Han Nuo hesitated a little, "because this place is adjacent to the Maoxian River, no one dared to dig a well here before I came, and everyone was worried that the well water was mixed with the poisonous water of the Maoxian River." ”

"So you dare to dig this well?" The elder surnamed Huang of the Purple Pole Hall also joined the inquiry.

"I have a lot of experience in sinking wells." Han Nuo smiled awkwardly.

"The pattern of this well...... The surname is Han, is the immortal master Mr. Han who relieved the drought in Anfeng back then? That week, Duguan took a step towards Han Nuo and looked him up and down.

"It was here, where did Lord Zhou learn about this?" Han Nuo found out that he had an extra personal witness, and he had a bottom in his heart.

"If that's the case, it makes sense." Zhou Duguan nodded, "Han Immortal's deeds have long been famous. The "Source Seeking Worker" written by the immortal master has been printed in several editions and spread to all counties and counties. Now it seems that the blessings of the immortal masters are not only all over the world, but even the prisoners in these mines are also covered with rain and dew. ”

"Is Lord Zhou a little biased towards Tianyun Gate?" Elder Xu looked displeased.

"I don't know if I'm partial to Tianyun Gate, Han Immortal Master, I'm biased." Zhou Duguan sneered, "Immortal Master Xu has ever seen a mortal miner with such complete clothes and such a ruddy face in his own mine?" He pointed to a group of people brought by Luo Jun.

Elder Xu of the Haoran Alliance also glanced at the miners, and saw that they were all full of energy and ruddy faces, completely different from those yellow-faced and thin-skinned miners in their own mines. Clothes can be changed temporarily, but people's spirit and spirit cannot be cultivated in three or five days. "When was this well dug in?" Elder Xu asked the miners.

"Immortal Chief, this well was dug by Han Immortal Master when he first arrived here, and it has been a year and a half now." Luo Jun stood up and replied.

Hearing this, Elder Xu was overjoyed in his heart, and finally caught some clues, "Why did you find the ore vein when you were sinking the well, but you only declared it at this time?" When Han Nuo heard this, he glanced at everyone, and stopped talking again, and stopped talking again.

"What is it inconvenient for Immortal Master Han to say directly?" Zhou Duguan saw Han Nuo's abnormal expression and asked.

"It's inconvenient, but it's not inconvenient...... I'm afraid that as soon as this statement comes out, not only will the face of our Tianyunmen be missing, but also the face of various sects. Han Nuo sighed, "If the discovery of a new mine had been reported at that time, I'm afraid the miners here would have worked twice as hard." ”

As soon as Han Nuo's words came out, everyone glanced at the nephrite mine that was about to be mined in the distance, and only a small hill remained.

Zhou Duguan also sighed deeply, and raised his eyes to look at the iron-faced elders around him. "I only hate the pile of white bones here, and I don't open my mouth for thousands of pieces, if I make the soft tongue have an inch of bones, I will be able to kill the immortals for a hundred years!"

"Lord Zhou, please remain neutral!" Elder Huang said hatefully.

"Elder Huang's Sect Bone Mountain is lower than this?" Zhou Duguan pointed the bamboo pen in his hand towards the bone mountain in the distance, and the arrogance of the literati calmed all the Jindan elders into arrogance.

"Ladies and gentlemen, don't let this hurt your peace. Not long after entering the immortal path, he didn't understand the rules of the immortal world, so he used some mortal rules to restrain his subordinates. Han Nuo immediately protected Zhou Duguan.

"Cultivation, cultivation, you have cultivated to become immortals, and you have cultivated to become iron-hearted. If it weren't for Han Immortal Master, I wouldn't know that the people here were not ants! Zhou Duguan was not afraid at all, but wrote hard in that booklet, "Don't worry, whatever happens here and now, this official will record it impartially and never show favoritism!" ”

Because Zhou Duguan made such a fuss, the atmosphere at the scene was extremely embarrassing. Han Nuo also looked incredulous, I don't know when the governor became his helper this week. He first arranged for someone to bring some wine, food, melons and fruits to greet everyone, and at the same time asked Luo Jun to start digging according to the several locations he had circled in advance.

Since it is mined from the ground, Hannuo naturally uses the deep well method. They first dug several round pits at designated locations, then erected a well wheel and used it to hang a basket for excavation. Because all the tools were improved by Han Nuo, the digging speed was also surprisingly fast, and it was quickly dug to a depth of 20 zhang.
