In order to be able to smoothly exchange for a sum of money, Tang Ning also took a lot of effort, not to mention the sale of too high-end treasure materials, it would be good if someone could recognize them, and this Nine Shadows Iron Essence Stone is the kind of treasure material that is very rare, but not too high-end, which Tang Ning collected on the rock wall at the bottom of Zhenlong Pond, and this thing is only available in extremely cold places.

Seeing that Luo Feng really knew this thing, Tang Ning was overjoyed, this was already the lowest ore on his body, if the people of the Luo family didn't know it, they would inevitably have to spend a lot of time, "Steward Luo is willing to buy this thing?"

Luo Feng was overjoyed when he heard this: "I don't know how many guests still have in their hands?

Luo Feng is also an intellectual, seeing Tang Ning hiding his true face, he knew that he didn't want to reveal his identity, so he never asked about the origin.

Tang Ning said: "Does Steward Luo know the value of this thing?"

People came and went in the Chamber of Commerce, and the two of them said in front of the counter, not deliberately avoiding it, Luo Feng naturally didn't say too much about the Nine Shadows Iron Essence Stone, and directly offered the price: "One or two dozen crystal coins, if the amount is large, you can add more." ”

Tang Ning just groaned slightly, then took out two fist-sized Nine Shadow Iron Essence Stones from the storage ring, and put them on the counter casually, this thing is extremely heavy, and the large fist has more than thirty catties, worthy of the name of iron essence.

The currency of this world is very complicated, in the world, gold, silver, and copper coins are the main trading tools, but in the cultivation world, crystal coins are used as the trading currency, and the exchange ratio between gold, silver and copper coins is decimal, and the exchange ratio between crystal coins and spars is also decimal.

The exchange ratio between crystals and gold coins is 10,000 gold coins for one crystal.

An ordinary spar can be exchanged for ten crystal coins, a medium-grade spar can be exchanged for ten ordinary spars, and so on, a high-grade spar can be exchanged for ten medium-grade spars, and there are still top-grade spars on top of the high-grade spars, but the best spars are very rare, known as the spar, and no one will take the spar to exchange for the high-grade spar.

Crystal coin is a regular currency processed from ordinary spars, which is actually a marketing method for crystal mine operators.

Ordinary spar is milky white, so it is commonly known as white crystal, the middle grade spar is red, and the top grade spar is purple, so it is called red crystal and amethyst respectively.

The price given by Luo Feng is not high, but it is by no means low, it can only be said to be decent, although Tang Ning is very proficient in all kinds of ore treasures through the "Yunqi Heavenly Recommendation Chapter", but he does not know the transaction price of these treasures, so he can only let Luo Feng bid.

Tang Ning went in and out of Zhenlongtan hundreds of times, but there were not many Nine Shadow Iron Essence Stones collected, only dozens of pieces, most of which were the size of fists, and the few pieces taken out were quickly collected by Luo Feng and exchanged for eight hundred crystal coins and placed on the counter.

Eight hundred crystals doesn't sound like much, but in fact it is a huge amount of money, in Qinghe Town, an ordinary family of five people, a year's living needs, no more than a hundred silver coins, that is, when Tang Hua was there, it was not considered meritorious, and the monthly income of the Tang Ning family was less than ten gold coins.

If you don't count the cultivation resources, it's just a necessity for life, and the consumption is ridiculously low.

The moment Shen Nian swept over the counter, the eight hundred crystal coins had already been put into the storage space by Tang Ning, and he didn't say much at the moment, turned around and left.

Tang Ning didn't think about choosing a short sword in the Divine Weapon Hall, but Shen Nian gave up after a little probing, the sword weapons placed by the Chamber of Commerce were extremely poor, and there was no one that could be seen, if it was customized, it would inevitably reveal his identity, and there was not enough time.

Leaving the Roche Chamber of Commerce, taking advantage of no one's attention, silently put the yarn hat into the space, and in the blink of an eye, it blended into the flow of people and disappeared on the street.

In the next few days, Tang Ning would find time to secretly go to the street once a day, in addition to preparing enough daily necessities, he also covered up his identity, went to the Lu family's Dan study, and searched all the various talismans and seals that he could buy several times, until all the eight hundred crystal coins in his hand were spent.

The talisman seals that the Lu family can put in the Dan study are naturally of a very low level, but they can't hold up a large number, and the categories are relatively complete, this is what Tang Ning thought of with great effort, and the best way to directly improve his strength at present.

The medicinal materials in Tang Mu's alchemy room were supplied to Tang Ning for free, with the intention of not using them in vain, he used them to process these medicinal materials in his spare time every day, and according to the "Dan Xinlu", all these medicinal materials were preliminarily quenched, and then put them into the storage space.

Of course, there was an opportunity to take advantage, how could Tang Ning be willing to let go, and let Tang Mu's maid take a lot of medicinal materials that were not available in the alchemy room, but were very cherished, and correspondingly, he also configured some ointments and powders for wounds and antidotes, which were for Tang Mu to see.

Half a month passed in a blink of an eye, and when Tang Mu came to the alchemy room again, Tang Ning had already made all the preparations he could think of at present.

Looking at the several medicines that Tang Ning had configured, Tang Mu frowned secretly, but he didn't say anything, and handed Tang Ning a badge and a jade talisman, the badge was a verdant leaf, this was the badge of a beginner pharmacist, the jade talisman was about an inch in size, warm and soft.

Tang Mu said: "You know the pharmacist badge, the jade talisman is used to enter the Taixu Secret Realm, come with me." ”

Tang Ning silently wore the pharmacist badge on his chest, rolled his belongings on his back with a piece of animal skin, and followed Tang Mu out of Qinghe Town and returned to Tangjiawu.

Tang Jiawu is martial arts training ground, a large group of people have gathered, Tang Ning saw Tang Ling, Jiang Xiuxiu and others at a glance, the young man in white was also standing with Tang Ling and others, Tang Mu said in a low voice: "Go to Tang Ling and them." ”

Tang Ning nodded silently and came to Tang Ling's side, but saw Jiang Xiuxiu, the young man in white and others looking at him in surprise.

Tang Ling tugged at Tang Ning's sleeve: "Did you also go to the secret realm of the family?"

Tang Ning nodded and said, "Why are there so many outsiders?"

In addition to Tang Ling and Jiang Xiuxiu, there are only a few people such as Tang Feng, Tang Yan, Tang Wei, etc., I remember that Tang Mu once said that every time the secret realm is opened, the time to enter and exit is limited, so the number of people who enter the secret realm each time is limited, how can the number of people gathered on the martial arts training ground at this time be nearly a hundred, but there are only a handful of people Tang Ning knows, can it not be strange.

Tang Ling sighed imperceptibly, and said in a low voice: "Jiang Xiuxiu, Tang Feng, and Tang Wei have all entered the door of the big names in their own family, and there are only three people in the Tang family in Qinghe Town, you, me, and Tang Yan." ”

Tang Ning couldn't help frowning, although Tang Yan was only two or three years older, she was already in the realm of building spirits, and she was the most outstanding genius in her generation, and she was a very high-grade golden spirit, but for some reason she was not accepted as a disciple by the so-called "big man", although Jiang Xiuxiu, Tang Feng, and Tang Wei were not bad, but they were not comparable to Tang Yan in the slightest.

Shen Nian quietly swept through the crowd, and Tang Ning suddenly found that there were still a few familiar children of the Lu family and the Luo family in the crowd, and they couldn't help but be a little vague about the qualifications to enter the secret realm, and as expected, most of these people were above the realm of the building period, similar to him, but only three or five people.
