Walking in the city at night, the traffic is busy, people come and go, and it is a prosperous scene.

Qin Mo walked alone on the streets, no one knew him here, and no one paid attention to him. Compared to Eternal Spring City, this nightly city is far more prosperous than Eternal Spring City. Although Qin Mo had never been to Night City, with his experience in this Nine Yuan Continent, he could figure out why this place was more prosperous than Yongquan City, but any place with good business would be prosperous, and this truth was true no matter where he put it. And this Nightwalking City was the only city with a refining guild in a large area nearby, thus attracting countless cultivators to come here. Because of this, no one would be curious when they saw Qin Mo, a six-rank martial artist, walking on the street. If Qin Mo was walking on the streets of Eternal Spring City, it was estimated that he would immediately be concerned by other forces to see what he was going to do.

Qin Mo was not in a hurry to go to the Refining Guild, but first found an inn to live in, which was his usual style. Settling down, it took Qin Mo two days to finally figure out the situation in Night City.

In the early morning of the third day, Qin Mo walked out of the inn again, Qin Mo first walked around, and it was almost noon before he slowly walked towards the Refining Guild.

The Refining Guild was a very large castle, and Qin Mo estimated that it should cover an area of nearly a thousand square meters. Of course, the castle was just the main building of the Refining Guild, and there were quite a few courtyards around it. At least the castle in front of him was the largest single building Qin Mo had ever seen.

Looking at the castle where people came and went, after a moment of silence, Qin Mo also walked towards the castle.

After entering the castle, the sound came to the surface, and it was as noisy as a vegetable market. Qin Mo had already been here yesterday, so he was quite familiar with the situation here. This is the first floor of the Refining Guild Castle, which mainly sells some magic weapons, of course, more of some dark iron weapons, as for spiritual weapons, it is rare to see in this first layer. Such weapons are in high demand, and because of this, this first layer is the most lively.

Qin Mo slowly walked past the stalls one by one, in fact, this place was just like the online Taobao store in Qin Mo's previous life, it was complicated and the real and fake goods were all placed there, and there was basically no control.

The staircase leading to the second floor was at the west corner of the first floor, which Qin Mo had already figured out yesterday. By the time he reached the western corner, the crowd was already less dense.

"Get out of the way, get out of the way!"

Qin Mo was about to step on the stairs and go upstairs when suddenly there was a shout behind him, and he just turned his head. A big hand pushed him aside.

"Young Master, please." Then Qin Mo saw a big man flatteringly make a gesture of invitation to a boy beside him.

The boy was shaking a folding fan in his hand, dressed in a luxurious pair, and had a crown of hair on his head. At first glance, you know that it is a noble son. What's more, the other party's cultivation is not weak, a fifth-grade martial artist, and the age looks like it should be twenty years old.

Qin Mo didn't want to make trouble here, this was not Yongquan City after all, so he put up with it. More importantly, this is not the harmonious and legal China, and if you provoke others, you may be killed. This is also what Qin Mo learned after coming to the Nine Yuan Continent, forbearance.

After the two of them had already gone upstairs, Qin Mo slowly walked up.

The second floor of the castle is for the sale of some real spiritual artifacts, and it is no longer as chaotic as the lower one, there are not many shops here, and many of them are idle. Of course, there aren't that many guests.

Qin Mo walked casually, he didn't want to buy magic weapons here again. Just take a casual look at the long knowledge, although he has already made certain achievements in cultivation, but he doesn't know many things on this Nine Yuan Continent, and he has to rely on himself to learn.

After turning around, Qin Mo naturally didn't buy anything, and then turned to the third floor, but there are still certain conditions for entering the third floor, if it is a refiner certified by the refining guild, then you can go up for free, but if you are not a refiner certified by the guild, you need to pay a certain fee to be able to go up. Qin Mo was naturally not a refiner, so after paying the gold coins, he went up to the third floor.

The third floor is the world that belongs to the refiner, on the third floor, you can buy the materials used in the refiner, of course, on the first floor of the castle, there are also some refining materials, but there are not many, and neither the quality nor the category is enough. But this third floor is different, after all, this is the world of refiners.

After Qin Mo walked to the third floor, he saw even fewer shops, and similarly, there were fewer customers here than on the two floors below. It can be said that it is deserted, after all, there are very few cultivators who have attribute spiritual power, and even fewer cultivators who have attribute spiritual power that belong to the fire attribute, plus not every fire attribute spiritual power cultivator can become a refiner. Once this is eliminated, there will not be many people left who can become refiners. Therefore, it is easy to understand that there are few guests on this third floor.

Qin Mo casually walked into a store, and the boss didn't pay attention to Qin Mo, but was looking at the books. Qin Mo casually looked inside the store, and of course, he was also paying attention to the materials he needed.

After reading it, Qin Mo didn't find the Red Flame Stone or Purple Ink Stone he needed. However, there are a lot of demon crystals, Qin Mo has long understood that this demon crystal is a very important thing for refiners, as long as the magic weapon above the spirit weapon is cast, the demon crystal needs to be used, and the demon crystal is the core material of the refiner. The attributes of a magic weapon mainly depend on the quality and rank of the demon crystal that is integrated into it when the magic weapon is cast.

Of course, Qin Mo also needed the demon crystal, but he didn't need to melt the demon crystal into the casting magic weapon. All he needed to do was redeem it.

After Qin Mo came out of the shop, he had already purchased two third-order demon crystals, and the price of third-order demon crystals was not cheap, each of which cost Qin Mo seventy or eighty thousand gold coins.

"If I collect all the third-order demon crystals, I guess the money will be almost spent. In this way, other materials can be purchased. Qin Mo walked out of the shop and muttered for a moment, "Put aside the matter of the demon crystal for the time being, these third-order demon crystals need so much money, not to mention the fourth-order demon crystals." Let's go buy Red Flame Stone and Purple Ink Stone first. If the matter of the demon crystal really doesn't work, go to the beautiful sister to ask for it. Qin Mo thought that Shi Xiaoxiao had killed so many third-order demon beasts, and there must be a lot of third-order demon crystals, so he saved money by asking her.
