In this world, there are many ores that are more precious than gold. Most people don't know this truth, but for those who refine ores, they do. Whether they are in this world or the world of Yu Yu in the previous life, they know a lot.

Some things have no field energy fluctuations, but they can still be used by monks, and monks also know its rareness. For example, a thing called california, this is a kind of ore known to Yu Yu in his last life, which is tens of thousands of times more expensive than gold. More than that, he has this kind of thing in his own hands. In order to refine the various things needed by the sect, Yu Yu has also stored various ores for a long time.

This california is the name of the time when Yu Yu lived in his last life. He actually didn't know it, he only knew gold. And this world, it is called Wujin.

It is very rare and can be used in all aspects, especially the high-level secular world. It can be used in a wide range, from housing to medical treatment. It can also be used to refine some pills used by mortals, so Yu Yu has a lot of these things in his hands. The reason why it can refine the pill for mortals is that this thing is unique.

With Yu Yu's identity and ability, he can buy almost everything that the world can buy, but he still doesn't have much of this stuff on hand. Large commercial firms can go to heaven and earth. Even so, they don't have much gold, and its preciousness can be imagined.

Zhen Yuanzi not only knows these precious things, but is also very familiar. After all, he has been mingling with Yu Yu for so long, just like Yu Yu is familiar with many weird formations.

Wujin, and gold, are two completely different beings. They don't have any symbiotic relationship, but they are born in one place at this time. But for all such extremely treasured things, their existence is unusual, whether they are used in the secular world or in the monastic world, whether it is the world Yu Yu is in now, or the technological world of his previous life, It's all true.

Zhen Yuanzi continued to dig back, which was very strange. Behind it was a layer of something rare in the monk world, called Yunni. This thing is an indispensable material for pill refining furnace, and the degree of cherishment varies depending on the quality of the cloud mud.

At one point, Zhen Yuanzi dug a channel, which is about a hundred meters away. After that, he dare not dig down, because faintly, he felt a very weak field energy behind. fluctuation.

He is just a soul, unable to deal with masters. If something inexplicable comes out from behind, he will be dumbfounded. At the same time, he is worried that Yu Yu's trace will be exposed after the fluctuation of the field fluctuates, so he gives up.

Seeing what he dug up before him, Zhen Yuanzi dug a few more places, and the results were the same. This place is a weird cave surrounded by several layers of very rare natural ores. I don't know where the water comes from. He studied for a long time, and the water was not corrosive.

That is to say, this water, it cannot make this place form a cave.

That is, other unknown forces have intervened.

It took more than a month before Yu Yu woke up. During this period of time, he was chased and killed by the opponent, and he was seriously injured many times, so that his vitality was not severely injured, but he should also take this opportunity to recover.

During this time, no one came after. In fact, he has proved his previous conjecture with Zhen Yuanzi that this place has formed a similar closed natural restraint that outsiders can't notice.

If Yu Yu hadn't come in by accident, he wouldn't have seen the peculiarities of this place.

Seeing him awake, Zhen Yuanzi was not very polite, and told him his observations and research results. When Yu Yu woke up, he had already discovered that there were weak field energy fluctuations here.

He tried to put in the spiritual sense, as he guessed it, like a clay cow into the sea, nothing could be detected. The back of the tunnel dug by Zhen Yuanzi, that is, the place where the field energy fluctuates, is like a black hole, sucking Yu Yu's spiritual consciousness into it, but it is not sucked in, it just makes him see nothing.

"None of these things can coexist." Yu Yu looked at the scattered ores on the ground, all dug out by Zhen Yuanzi. "Do you think there is a formation mage like you? He established a small formation, then This is the place where his bones are buried? All these things appeared because of the formation restriction. Otherwise, the explanation won't work!"

"There is a good formation here, but it's no longer valid." Zhen Yuanzi said. "I don't know if this person is an ancient formation mage like me, but I can be sure that this person has good formation skills, but it is not good enough. To my level."

Yu Yu glanced at him. This Zhenyuanzi is good in everything, but he is a little proud. When it comes to the formation, he is simply the second in the world, and no one dares to recognize the first.

"Okay, you go on to say" Zhen Yuanzi announced his opinion seriously and solemnly, Yu Yu had no choice but to nod his approval. Only then did Zhen Yuanzi continue to say, "Behind this place, if I didn't guess wrong, it should be a space similar to a cold jade carving. It is not a small world in itself, but... well, it's like a big rock hollowed out. Then you can live like a person"

"Then these things outside here, as well as this cloud mud... This thing is used to refine the pill furnace. It looks average, not very good," Yu Yu said, shaking his head. "Moreover, most of these things are They are all mundane things."

"All this is what the average person sees." Mamotoko is quite proud. "This place~lightnovelpub.net~ is not a naturally formed cave, it is like this, but I guess, its original space It may be relatively small. There should be a layer of ordinary stones on the outer layer of the gold ore. Now these stones have fallen because of their age.

The falling of these stones is actually related to the failure of the formation here, otherwise the stones outside on your layer would not fall. That layer of stones should be used to confuse people who come in. There is no fluctuation in field energy here. When you enter this realm, you can't find it, and outsiders don't even think about it. So it’s easy to fool ordinary people"

"It makes sense," Yu Yu said. "Then the key is coming, is the cold jade carving space you guessed later?"

"Well, that's the case, but the space for cold jade carving itself should be something used by monks who are not good, but not bad. After all, there is still energy fluctuations. If you dig it out, there will be a lot of Obvious field energy fluctuations.

And back to what I just said, the reason why the average person looks nothing here is that the outside is wrapped in mundane things. And this is precisely the genius of the array mage. In the beginning, these things, I guess, appeared when the formation was first completed. The purpose of their existence here is to cover the field energy fluctuations emitted by this cold jade. "

"I rely on" Yu Yudao "There is also such a formation, can't you and I be covered..."

"Wait." Zhen Yuanzi waved his hand. "How easy is it to completely cover the fluctuations of the field. This place is connected to the mountains and rivers outside, the direction of the ground, and the hub of the link is those things. ..."

Zhen Yuanzi pointed not far away.

"water!"
