For a long time after that, Hannuo and the miners in the mine lived a relatively stable life. The sect also did not strengthen the guards of the mine, and even removed two disciples to show that it did not pay attention to the Yunsi gold mine.

Because Han Nuo knew that the core of keeping the mine was to please the upper echelons of the sect, he simply concealed the true output of the mine, and only handed over enough cloud silk gold to make three sets of semi-cloud silk armor every year.

At the beginning, the new refining elder also used cloud silk gold to refine the cloud silk armor by himself, but later found that the refining process was too energy-consuming, so he simply asked Han Nuo to directly hand in the semi-finished products, so Han Nuo reduced the output of cloud silk gold to three sets, and his reason was that it was more time-consuming to become a armor by the way when extracting cloud silk gold. At first, there were still elders who asked, but later everyone found out that the Yuanying elders who stayed in the sect had already had a set, so they acquiesced.

Of course, there were also elders who wanted to trick him into refining the secret of cloud silk gold, but Han Nuo was fooled by a very complicated machine, and what really worked was only two copper pipes for ventilation.

Because of this, Hanno did not expand the scope of mining, but kept an eye on the mining of several pits dug before. The daily task of the miners is to enter those pits and extract a small piece of cloud gold ore, so that they can move freely.

And because the amount of Yunsi Gold Mine is very small, and the sect no longer sends personnel to escort it, Senior Sister Nan Qian just took Xin'er to see Luo Jun at random. So Luo Jun was bored and taught Han Nuo some very powerful swordsmanship in the mortal world.

There is a saying that "there are a hundred people, all kinds of people". Han Nuo not only learned sword skills from Luo Jun, but also learned some strange skills from other miners that could not be learned in the immortal cultivation world.

Of course, the sect also gave Han Nuo some sweetness to show his praise for his meritorious service, one was to announce the protection of the Han family's firm, and the other was to give Han Nuo the authority to dispose of the waste from the mine.

Perhaps for ordinary immortal cultivators, those mine wastes are really wastes. But for Han Nuo, who has broken through the high-temperature flame technology, it is like a treasure. Because he discovered two secrets of the mine.

The first secret is the secret of the Silk Gold Mine. It turned out that when Han Nuo extracted the cloud silk gold, he unexpectedly found that the melting point of the cloud silk gold was lower than the melting point of its substrate, and when the flame color of the flame turned white and blue, the cloud silk gold would turn into liquid, and it could be collected like a cocoon pulling a filament.

The remaining substrate will be very light due to the extraction of cloud gold, but its texture is very hard. Hanno tried to speed up the gas flowing through the nozzle until the flames turned sky blue, and the substrate became very soft, somewhat like plasticine. But once the flame stops, it becomes very hard again.

Only then did Han Nuo understand the origin of the name Yun Silk Gold, it turned out that the base material was cloud, and the so-called Silk Gold may be some kind of metal element that has appeared on the earth, but Han Nuo couldn't tell what kind of element it was. He began to regret that he didn't study chemistry, otherwise it might have been of great use.

And that substrate was used by Hanno for a special purpose - to make tanks. But this kind of thing was obviously more difficult to refine than Yunsi Gold, so much so that by the time he left the mine, he had only obtained an object that looked like a turtle shell.

The second secret is that there is a lot of sand on the side of the Maoxian River. This is not a secret in this world, but for Han Nuo, it is an important resource to make up for some costs for himself.

The discovery of the beauty of sand originated from a whim of Han Nuo. He wanted to try to realize semiconductor technology in this world, but when he grabbed that handful of sand, he found that he didn't have the slightest knowledge of semiconductor technology in his head. When the book is used, I hate it less, not to mention that I didn't take it seriously at the time. So in the end, he burned a glass bottle.

Firing a glass bottle is undoubtedly a matter of skill for mortals. But for immortal cultivators who can control the shape of objects with spiritual power, it is a very simple job. So the glass bottles he fired were so beautiful that he even embedded some minerals in them that glow in the night.

The first reaction to this glass bottle, Han Nuo naturally sent it back to the Han family's firm, and asked them to fill it with fine wine, ready to give it to their master Liu Yan in person. But after getting this glass bottle, Han Hexian immediately asked Chen Zhao to bring back a letter. In the letter, she called the property priceless and asked if the firm could monopolize the right to operate it.

Han Nuo, who received the letter, made a set of glass drinking utensils by himself. This time, he not only mixed it with luminous ore, but also inlaid it with silk gold, and recreated a more beautiful bottle, which was also inlaid with hair-thin silk gold.

After that, he personally went to the Han family's business and asked Han Hexian to take out some of the wine he had ordered him to make and put it in the bottle. The previous glass bottle was handed over to Han Hexian to dispose of by himself.

What Han Nuo didn't know at the time was that Han Hexian handed it over to his brother to sell, and Han Heming sold the glass bottle at a sky-high price with his excellent business skills. And that income directly wiped out the firm's expenditure on the mine.

However, Han Nuo didn't care too much about this matter, and he returned to the sect with fine wine the next day. After some inquiry, he learned that Master had moved back to Tianyun Peak and was no longer in charge of all the affairs of the refining room.

Han Nuo found his master in the Yajing cave before, and when he learned that the cave that Liu Yan borrowed him was really her own cave mansion, he was surprised like a Westerner who had eaten preserved eggs for the first time.

Liu Yan had already known about his arrival, after all, as a Yuanying Cultivator, his divine sense could already explore hundreds of miles away. And Han Nuo had the spirit mark she planted on his body, so he was naturally sensed as soon as he returned to the sect. Therefore, as soon as Han Nuo arrived outside the cave, a path opened in the clouds.

As soon as Han Nuo entered, he saw Master sitting on a lotus leaf in the center of the cave and practicing. When Liu Yan saw him, the corners of his mouth raised slightly, but he didn't say anything.

"Unscrupulous apprentice Han Nuo visits Master Master." Han Nuo exaggeratedly knelt on the ground and raised his hands to make a big salute, which made Liu Yan laugh.

"You rebel, you don't see any progress in cultivation, but people have slipped a lot!" In just an instant, he came to Han Nuo, "Say, what bad ideas do you have again?" ”

"Don't dare! Recently, the apprentice came across a pot of fine wine, and remembered that the master was quite good at it, so he immediately sent it up the mountain. Han Nuo took out the wine and set it in front of him.

"Huh! Golden silk glass cup! Where did you get it? Liu Yan picked up a wine glass in surprise and took it in his hand to observe it carefully.

"Huh?" Han Nuo was stunned for a moment, he didn't expect this thing to have such a high-end and high-grade name, and he didn't know how to answer for a while.

Liu Yan looked at Han Nuo, pursed his lips and shook his head, "That's it, looking at you like this, you must not recognize this thing, otherwise you wouldn't have used it to hold wine." And this thing has its form, but it is not an immortal weapon with infinite magical powers. Tell me where this wine came from. ”

"Master, please take a look." Han Nuo sat up, opened the wine bottle and poured out a glass of wine, "Grape wine glow-in-the-dark cup, if you want to drink the pipa, urge immediately." ”

"Oh? This poetic mood is good, the next sentence? Liu Yan took the wine handed by Han Nuo, tasted it gently, and suddenly showed a satisfied look on his face.

"Drunk and lying on the battlefield, don't smile, a few people have come back to fight in ancient times." Han Nuo continued.

"Good poem, the person who wrote this poem should be a pen catcher, right?" Liu Yan took another sip, "This wine is also quite charming, I like it very much." ”

"If the master is satisfied, it is good wine." Han Nuo said with a smile.

"This is the design artwork of the exoskeleton armor, your attainments in refining cloud silk gold are quite amazing, this thing will be given to you!" Liu Yan threw Han Nuo a jade plaque, and Han Nuo was overjoyed when he saw this, holding the jade plaque and thanking him again and again.

"Don't be in a hurry to say thank you, the main material of this armor is the skin of some low-level demon beasts. But if you want to really exert its power, it has to be a high-level material such as cloud silk gold, but with your current cultivation, I'm afraid you won't move. In the opinion of the teacher, you should still improve your cultivation as soon as possible and spend less time on handling such items. Liu Yan said as he played with the wine glass in his hand.

"Master Xie for your guidance." Han Nuo thanked him, guessing in his heart that Shizun must have felt that he had spent a lot of energy on this set of wine utensils. If he knew that this thing could be made in the blink of an eye on the earth using assembly line technology, he didn't know how to feel it.

After coming out of the Liuyan Cave Mansion, Han Nuo soon returned to the mine, and while he couldn't wait to improve his exoskeleton armor with the cloud silk gold he had secretly saved, he was also studying mixing various ores in the sand to create different 'glass cups'.

This gave him two takeaways.

First, referring to Master Liu Yan's design ideas, he changed his exoskeleton armor to be very suitable for him to build a foundation for cultivation, and wearing this suit of armor, he even has the strength to fight with Brother Jindan. So he gave the suit a name - Sky Armor.

The second harvest is that after trying a variety of different ore combinations, he finally mixed a small amount of sand with the base material of Yunsi Gold Ore to make something similar to translucent glass, and the biggest characteristic of this material is that one side is transparent and the other side is opaque. However, its hardness is no different from that of cloud silk gold stone.

Han Nuo used this material to make two long swords, and after matching them with the Sky Armor, he felt that he had become a cool and handsome immortal cultivator for the first time. The surplus materials for sword making were used by him on the semi-finished tank, which became bulletproof glass for the observation window.

If life goes on like this, Han Nuo may defend this mine and eventually succeed, and by the way, become a powerful man who is rich and rival the country.

However, just like no one can work in a job until retirement, Hannuo's life also ushered in a turning point three years later.

On that day, Han Nuo was experiencing some indescribable changes in his body, and it turned out that the true yuan in his qi sea had actually given birth to something similar to crystallization. It is a physical change from a gas to a liquid and from a liquid to a solid. However, Han Nuo couldn't figure out the reason for the crystallization for a while, it seemed that just like water freezes, it needs some specific substances to solidify it. However, when he felt that the crystal appeared, his spiritual power increased a lot.

While he was still meditating on the principle of the crystallization, Guo Hong, who was on duty, came to his tent. "Uncle Han! New mines have been mined again! Despite the excitement of the visitor, he stopped outside the door with restraint.

Han Nuo frowned, took his work, and slowly paced out. "What new mines?" He looked at this new Qi Refining Disciple with a very indifferent expression. It turned out that Zhuo Ke and his group had already participated in the sect trial two years ago, and unexpectedly, only Chen Zhao and another disciple who was usually inconspicuous had passed the trial and successfully built the foundation, while the rest of them could not come back.

"Please ask Uncle Shi to identify, it looks like it may be a spirit stone mine." Guo Hong handed him a glimmering stone, and Han Nuo glanced at it, but it turned out to be a moonstone.

"What's the fuss, haven't you seen the spirit stone? What does your spirit stone look like this? Han Nuo suppressed the excitement in his heart and said calmly. Come with me and see. ”

A moment later, the two of them came to the pit where the moonstone had been mined, one of several pits that had been being mined. Sure enough, watermelons can't be stolen from one place. Han Nuo muttered in his heart.

"Brother Han, what should we do next?" Luo Jun crawled out of the pit and happened to bump into Han Nuo, so he immediately came up to say hello.

"First stop digging downward, temporarily seal this pit, and the new mine must be declared to the imperial court, and only after supervision and examination can it be mined." Han Nuo instructed Guo Hong, "All miners are allowed to rest for a few days, and they are not allowed to return to work without my notice." I want to go back to the sect to report this matter, you guard this place, and if there is an emergency, you can release a thousand miles of lanterns. ”

With that, Han Nuo flew towards the sect with his sword.

A few hours later, Han Nuo arrived at the main hall of the sect. On the way here, he sent her a brief message through a unique communication tool given to him by Master Liu Yan, so when he arrived, Liu Yan was already waiting for him on the third floor of the sect hall with several Yuanying elders.

"What surprise did you bring us this time?" It was Ye Mingsong, the second elder of the sect, who spoke, and it seemed that this person was more concerned about the affairs of the mine.

"Elder please take a look." Han Nuo respectfully held the moonstone in his hand, and Liu Yan recognized it at a glance, and his face changed instantly.

"Judging by Elder Liu's reaction, could this be the moonstone mine?" Elder Qi pointed his finger and took the ore over. The ore stopped in front of everyone, emitting a faint light, and Liu Yan struck the ore with a spell, inspiring a soft light.

"It's indeed moonstone." Elder Deng nodded and looked at the Second Elder, his face full of solemnity.

For a moment, everyone in the hall was silent. In fact, Han Nuo knew in his heart that the reason why this situation occurred was because the moonstone ore was originally an associated mineral of the spirit stone vein. The mining process of spirit stone veins is different from that of other ores.

For the mining of the rest of the ore, as long as the sect forces that found the ore veins are declared to the imperial court, and then the imperial court arranges a supervision team to supervise the mining process, and the sect can be freely mined after the process is completed.

The mining procedures of the Lingshi mine will be more complicated, although there is still a corresponding supervision process, but after the supervision process, there will be a joint and challenge link of each sect. And it was this link that silenced all the ancestors present.

It turns out that spirit stone is a kind of hard currency that is customary in the world of cultivating immortals, and the sect that discovers the spirit stone mine is generally not exclusive to it. At this time, the sect can choose to form an alliance with other sects to share this vein, while the rest of the sects can challenge this alliance. If the challenge is successful, the rest of the sects can be divided into fifty or fifty with the allied sects, and if the challenge fails, all the spirit stones will belong to the allied sects.

Therefore, there are two problems faced by the sect. First, we must start thinking about which sects to form alliances with now, because this will directly affect the sect's spirit stone division. The second is whether to recall the Great Elder and other infant monks who have traveled abroad. Because usually the participants in this kind of challenge are Yuan Infant cultivators, after all, no one wants to give away the spirit stones in their hands.

And the most important thing is that on top of this spirit stone vein, there is also a layer of cloud silk gold mine, if the personnel of other sects enter the mine, then it is only a matter of time before the secret of cloud silk gold and cloud silk armor is exposed.

That night, Han Nuo returned to the mine with a blank face, he didn't say a word about the trip to the sect, and no one dared to ask any disciples. But from that day on, the mine went into a long shutdown.

As for Tianyun Gate, several summoning orders were suddenly issued, and Great Elder Ximen Mu returned to the sect five days later, and the other four Yuan Infant Ancestors who received the summoning order also returned to Tianyun Peak one after another before the end of the month.

On the third day of the next month, in the main hall of the sect on the top of Tianyun Peak, plus the newly married Elder Liu Yan, a total of eleven Yuanying monks gathered in the center of the main hall. And around them, there were hundreds of Jindan monks in Qingyun robes densely lined up.

For an ordinary sect, having three or five Yuanying monks is a big sect. But because of the spirit washing vein recipe, Tianyunmen had a Jindan explosion two hundred years ago. Although there were many people who ended up with the same true yuan leakage as Elder He Yuanqing, there were still nearly twenty people who successfully got married. As a result, Tianyunmen was unrivaled for a while, and it became the first major sect in the kingdom.

It was precisely because of this that Tianyunmen was able to obtain a large amount of land and resources from the imperial court. There are as many as three mines like the one guarded by Han Nuo. And this time, the purpose of the sect's elders' meeting was to discuss the nephrite jade mine where both the Yunsi gold mine and the spirit stone mine existed, so that the sect could get the most out of that mine.

The council lasted three days, and after several rounds of deliberation came to no conclusion. The Council of Elders formed three factions: the allied faction led by Elder Qi and the Imperial Power Sect, the Shoucheng faction led by Elder Yun Yifei who temporarily did not declare the spirit stone vein, and the exclusive faction led by Elder Deng and Elder Hao.

In the end, under the opinion of the Great Elder Ximen Muli, the Elder Council chose not to form an alliance with any sect, and the Tianyun Sect had the opinion of exclusive access to the ore vein. This opinion is the most difficult, but it is the most beneficial for Tianyunmen.

In making this decision, Elder Ximen Mu said three reasons: first, the magic of Yunsi Gold may eventually be exposed over time, and in the current situation, Tianyunmen's advantage is the greatest; The second is that in the past two hundred years, Tianyunmen has only produced a new Yuanying monk in Liu Yan, if it is not taken advantage of the fact that Elder Deng and the others are still alive to take over the new mine, the sect may continue to decline in the future; And the third point is because the moonstone mine found so far is also a very important material in Tianyunmen, and the three mines currently exist together, if this battle can be won, then all the minerals in this mine will always belong to Tianyunmen.
