The most lively place is a pair of blacksmiths and apprentices set up a furnace, they are not afraid of the cold of early spring, directly bare-chested, pick up a sledgehammer, and make swords and weapons on the spot. The sound of tinkling, very rhythmic and rhythmic. The weapons created were cold and shiny, and the sharpness was compelling, attracting many survivors to come and watch and ask for a price.

Jiao Bai mostly relied on summoning beasts during the battle, and he was not very interested in these cold weapons, so he didn't surround them to watch. The two walked a long way along the edge of the square, and during this time they came across a stall selling crystals, Jiao Bai squatted down, touched all the hundred and ten crystals on the stall with his hands, and couldn't help but shake his head in disappointment. These crystals are generally not of high level, the fourth level is the highest, and the types are mainly mutant beast crystals, and the only dozen or so zombie crystals are also below the third level.

The owner of this stall was a thin middle-aged man with a mustache, and when he saw that Jiao Bai seemed to be interested in buying crystals, he hurriedly said: "Brother, do you want to buy crystals, I have all levels and types of crystals here, whether they are used for weapon smelting or for preparing potions, I can find them here." ”

When Jiao Bai heard this, he asked with interest: "There are some mutant beast crystals that can be used as additives when smelting metals, I know this." What's the deal with the potions, can you give me a look. ”

The middle-aged man hesitated for a moment and said, "This is also relatively secret news, if you want to know, buy a few crystals first." ”

"That's fine, there are a few crystals in your pile that I need."

After that, Jiao Bai seemed to pick out all the dozen or so zombie crystals at random, including a third-level Night Walker crystal, which carried a master-level mechanical processing skill, which was the most valuable in the stall.

The stall owner counted the crystals picked out by Jiao Bai, took out a notebook and inquired, and then said: "7 first-class crystals, 9 second-level crystals, and one third-level crystal, a total of seventeen." How are you going to pay the bills, bullets or food? ”

Jiao Bai took out a few bags of compressed biscuits from his carry-on space and said, "I use these compressed biscuits to pay the bill, one bag and one catty, how many bags do you think?" ”

Seeing that Jiao Bai was able to take things out of thin air, the stall owner was shocked for a moment, and then became respectful, and arched his hand to Jiao Bai: "I didn't expect that my brother turned out to be a space system evolutionary, and I was really snub just now." These crystals, you can give five catties of compressed biscuits. ”

Jiao Bai nodded, counted out five bags of compressed biscuits and handed them to the stall owner, which was considered to be an endorsement of this trading plan. After putting a dozen crystals into his personal space, Jiao Bai continued: "What does it have to do with the crystals and potions that can be given to me now?" ”

"Of course, in fact, this is not any top-secret news, and it is still very widely circulated among high-level evolutionaries. It is said that after advancing to the fifth level, those who understand pharmacy or biology may be able to work as a pharmacist. Apothecaries, on the other hand, can use mutant beast crystals and other raw materials to process some potions with strange functions. For example, the growth liquid used by the Sea Gang to cultivate a large number of mushrooms, and the super healing spray that the marines are equipped with in large quantities, these are the masterpieces of the pharmacists. ”

Jiao Bai didn't expect that the mutant beast crystal could still be used like this. He also has a deputy position as a pharmacist, and he learned it together with a mess of deputy positions such as blacksmiths, carpenters, and inscriptionists, and spent a lot of money to pack them together. It's a pity that Jiao Bai is just a pharmacist deputy position, and he doesn't know anything about potion formulas or anything.

After saying goodbye to the stall owner, the two continued to walk inside, Jiao Bai took out a zombie crystal, showed it to Xu Ping, and then asked, "Do you know where you can buy this kind of crystal in large quantities, preferably the kind of zombie crystal with a relatively high level?" ”

Xu Ping took the crystal in his hand and played with it, then returned it to Jiao Bai, and said, "According to the news I heard, this crystal is divided into low, medium and high according to the level of the mutant beast zombies. Low-grade crystals are the product of killing first- to third-level zombie mutant beasts, with a large output, low energy, and a very low price. Medium crystals are the product of killing level four to six zombie mutant beasts, the quantity is very scarce, and the value is very large, the three major organizations have been buying at a high price, and it has been used as an equivalent exchange for bulk goods for a long time, and to a certain extent, it acts as a large amount of currency. The high-level crystals are theoretically the product of killing zombie mutants above level seven, but this level monster is too powerful for the current evolutionaries, and I haven't heard of anyone who has obtained high-level crystals. ”

"The three major organizations, this is not easy to operate......"

Jiao Bai touched his chin and groaned. It is not too difficult to obtain medium zombie crystals from the hands of the three major organizations, as long as Jiao Bai takes out a large amount of food, they will be very happy to exchange it. Just in this way, the fact that he has a lot of food is exposed. In the last days, the importance of food cannot be overemphasized, as long as the news leaks out, I don't know how many people will come to him for trouble.

"Master Jiao, don't you want to buy antique calligraphy and paintings, just in front."

Xu Ping's words woke up Jiao Bai in contemplation. He looked up and saw that the two had reached the deepest part of the square. The location here is remote, there are not many survivors coming and going, most of the stalls are ordinary people, and most of the people selling are not very valuable clothes, shoes and hats, oil, salt, sauce and vinegar and other daily necessities. Of course, antique calligraphy and paintings, gold, stone and jade can't be eaten or used, and they are also classified here, and these things are placed in the few stalls near the left of where Jiao Bai and the two of them stand.

Jiao Bai first came to a calligraphy and painting stall, first browsed a few paintings that had been hung up, and then took out a few of the scrolls randomly inserted in the porcelain vase, and opened them one by one to check. From the layman's point of view, these paintings look like genuine works. Fortunately, Jiao Bai has perceptual skills, and can detect the details of these things, and after a few skills, the age of painting, the author's information, and all are presented in front of Jiao Bai, all he has to do is to select some authentic works from them, or copy paintings that are older.

The owner of this calligraphy and painting stall is not a complete liar, and among the hundreds of paintings, there are still more than a dozen real ancient paintings. Jiao Bai found a picture of Zhao Ji of Song Huizong from it, which focused on depicting eighteen red-crowned cranes with different postures, soaring and hovering above the Xuande Gate in Bianliang, and there was also a text written by Zhao Ji in thin gold and many collection seals next to it, which is a treasure with a clear origin and orderly inheritance. If it is brought back to Earth for auction, the transaction price will not be less than 5 million. ：，，，
