?? Li Nan didn't go to look at the books that those scholars were reading, but walked to the miscellaneous history books. If you want to understand the specific situation of a place, you have to read miscellaneous studies and history books, although these things are not necessarily true, but they certainly will not be all fake, at least some of the general directions are still accurate.

It is possible to delete the bad deeds of Emperor XX a little and exaggerate his merits, but it is absolutely impossible to change the dynasty, the emperor's name and the like.

Since the last time he forcibly instilled knowledge, Li Nan has read books much faster, even if these words are similar to classical Chinese, Li Nan still quickly browses through them, and he can know the general meaning and content.

Quickly flipped through a few history books and some miscellaneous records, and it was easy to find that there were indeed immortal cultivators here, but they didn't appear frequently. The mortal kingdom still has a court and a variety of government agencies.

The existence of practitioners is only occasionally circulated, and it is not even recorded in the official history, and most of them are only found in miscellaneous anecdotes.

Slightly disappointed, he left the library and went straight to Yuyang Mountain, which was rumored to be infested by immortals, and was the closest to this side.

I found a place where no one was and teleported over, and the dazzling green came straight into view. The mountain is not tall, but it is very green, and as far as the eye can see, there is hardly any color except green.

Normally, mountains are basically mountains, and there are few independent mountains, just such a mountain stands over there.

Li Nan doesn't know anything about the formation, but he has technology. Life detectors, ripple scanners and other small equipment, Li Nan has always been stored in the space, at this time to take out and debug, it is easy to find that there is a gathering place of people in the mountains.

And the surface light waves of those people detected were not the same as those of normal ordinary mortals, and there seemed to be an extra layer of aura waves on the surface. Overall, it's just a ripple that sticks out, a few more turns than other normal mortals.

Although Li Nan knew that there were people inside, he didn't know how to get in. And he's a beginner, so there's no reason to go in.

Therefore, I can only leave here quickly, and then rush to other cities, hoping to find a gathering place for weak monks or casual cultivators, such a place, although it is relatively dangerous, but it should also be easier to access.

The hard work paid off, and after Li Nan teleported for a long time and used the ripple detector many times, he finally found a small gathering place, and looking at the gathering place that was similar to the gathering place of ordinary mortals, there was no restriction on the cultivation of those who entered.

It was in a city, which was obviously much larger than the others, and seemed to be the capital of a certain country. However, Li Nan didn't care what country it was, anyway, it didn't have much to do with him, he didn't come here to visit this mortal realm, he was mainly looking for cultivators.

It was in a corner of the eastern part of the city, and there was not even a formation outside, but there was something similar to illusion to cover it.

Li Nan didn't know it anyway, but through some technological equipment, he was able to clearly detect the existence of many cultivators in it. I tried to go straight through the city wall, but the wall didn't seem to be an illusion, and it was still solid.

At this time, the knowledge of reading novels before was useful, and he gathered the few spiritual energy in his body into the palm of his hand, and pressed it towards the city wall again. Sure enough, this time I was able to get in smoothly.

There were quite a few people inside, and at first glance it looked like a mortal bazaar, and some of them even sold their own things on the streets.

"Pei Yuan Dan, Yuan Jing Dan, Forging Body Pill, Detox Pill...... Sold cheap!"

"All the low-grade spirit grasses that have just been picked have been packaged and sold, as long as ninety-nine grade spirit jade, as long as ninety-nine grade spirit jade. ”

"Talismans, all kinds of low-level talismans only need to be exchanged for demon beast essence blood!"

All kinds of cries and selling voices emerge in endlessly, and Li Nan can hear from these voices that the level here is definitely not very good, and what is sold is low-level things.

Just walking around, he didn't know what to buy, and he didn't know most of the things here. At this time, I suddenly saw a stall selling all kinds of metals, and it was not raw ore, it was the kind of metal that had been forged.

The key is that there is a metal that Li Nan recognizes and looks very beautiful, called Nebula Gold, which ranks 28th on the Tunguska Empire's metal ore precious list. It is a restricted mineral for mecha crafting, and private trade is not allowed, and if an individual accidentally obtains this metal ore, it can be traded to the state.

The price is very expensive, it is calculated by grams, 5000 credits per gram.

Li Nan was worried that he didn't have many credits, and he didn't know how to earn credits, so when he saw this thing he knew, he naturally squatted down and asked the price: "Hello, how to sell this Nebula Gold?"

The ore seller was a muscular man, who looked very vicious, and even had a small scar on his cheek: "Nebula Gold? Oh, you mean Divine Gold! This doesn't seem to have any effect, it can connect to the Divine Sense, but this quality can't be used as a Divine Sense weapon at all, so you can only make your own weapon a little more coordinated with yourself!"

Are you sure you want it?"

Of course Li Nan asked for it, but he didn't know the specific price: "Yes, I want it, I just don't know if this is expensive?"

"Ha! How can this thing be expensive? A piece of low-grade spirit stone is one or two, how many catties do you want?" the big man didn't care about such a small deal at all, and asked casually.

Li Nan decided that if he could buy it, he would buy more and go back, and get enough credit points at one time, so as to save himself from repeating the transaction in the future, which would be even more suspicious.

So I asked with some worry: "I think this is very good-looking, can I buy more?

Dahan was stunned for a moment, then quickly counted his inventory, and said with some uncertainty: "Are you sure you want it? It's useless to buy so much, I have inventory here, but there are still a thousand catties, but are you really sure you want to buy so much?"

He really couldn't figure out why he bought so much at once, this kind of metal is not widely used, and it is generally only used to forge top-level mortal weapons, which is the kind of weapon that feels quite spiritual among martial arts masters.

Therefore, this kind of metal belongs to the kind of thing that ordinary mortals basically can't get, and cultivators don't want it.

"Yes, can you sell them to me?" Li Nan asked excitedly.

"This costs more than 10,000 grade spirit jade, are you sure you can afford it?" Huatai has been doing business here for many years, and after so many years, the transaction volume must be more than 10,000 grade spirit jade, but it is the first time he has encountered such a large transaction amount at one time.
