Xiao Wu closed his door for less than a month to refine materials, and a month later he began to come out and wander around, the frenzied acquisition of materials and data classics in the previous months seems to have attracted a lot of people's attention, and the opportunity to use refining materials to avoid it for a while, it is estimated that it should be no problem now. And as the trading conference approached, there were more and more strange monks entering Tianhe City, and no one should pay attention to such a small monk as him. During this time, there are really a few things that need to be dealt with, the first is to find a way to get a chance to enter the auction of the four courtyards, and the second is to ask the refining master in the city for the experience of refining magic weapons, after all, his refining cognition is obtained from the data classics, and before he really starts refining magic weapons, he has to ask the real refining master for guidance.

He first went to a huge auction building in the city, and I don't know which branch is behind this auction building, this auction is said to be held in this huge attic, and during this time this building is collecting auction items, if the value of the items taken out is large enough, this auction building will give away a number plate, and this number plate happens to be the identity card to participate in the auction. Xiao Wu didn't even walk into it when he saw a lot of monks walking in and out, some of them were excited and some were gloomy, it was estimated that these people were here to identify the items in their hands, he didn't hesitate, and directly entered the huge hall inside, which was very quiet, completely different from the complicated scene outside.

A young man who looked like Xiao Si was standing next to the door, and when he saw Gu Xiaowu walking in, he bowed down and said: "If the Immortal Master is here to identify the materials, please go to the left, as long as the door is open, you can go in for identification, if you come to exchange treasures, please go to the right."

Gu Xiaowu looked at the left and right of the hall, and immediately walked towards a room on the left that was opening the stone door, but before he could enter it, a stone door next to him opened, and a young man in a purple robe walked out with a gloomy face, and when he saw Gu Xiaowu, he was stunned and said in surprise: "Such a coincidence, Senior Brother Gu, you also came here to identify treasures?"

"It turned out to be Senior Brother Ma, don't you want to try your luck here?" The one Gu Xiao Wuyi saw was the disciple of Jiuyin Valley who came to Tianhe City with him, he was very enthusiastic, and they chatted a few words on the way, and they knew each other.

"Alas, this auction is really his grandmother's not so easy to participate, junior brother, you can go in and try it, if there is no sect in this city, you will be bullied by those black-hearted guys, for my brother and several other junior brothers live in the Longju Pavilion in the southern city, we will not be angry only if we act together, and if the junior brother is free, you can go there to find us." This Senior Brother Ma turned around and left as soon as he hugged his fists, it seems that he didn't get an identity plate as he wished this time.

Gu Xiaowu entered the stone house, and then the stone door was closed, and there was only one eighteen or nineteen-year-old young man in the stone house, except for Xiao Wu, who was leisurely tasting a cup of spiritual tea and looking at the little cave who came in with the residual light of his eyes. Xiao Wu didn't dare to have such a large number of this young man, because as soon as he came in, he sensed that the other party was a genuine Cheng Dan stage existence, and he didn't know if he was originally very young or had the ability to stay good.

"What materials need to be identified, my time here is very precious, and I don't accept things of little value." The young man put down the teacup before he said impatiently.

Xiao Wu didn't say much, and directly put a prepared space bracer in front of the young man, which was filled with blood coagulation essence soil, which should be able to meet the standards of the auction.

"Huh? Such a lot of blood condensation essence soil? 500 million spirit stones, do you sell them to us now or are you going to hand them over to us for auction, let's say it first, we will take half of the income from the auction. The young man was very surprised, this cave building had the materials needed for the cultivation of the Cheng Dan Void Spirit in his hand, and he also had so many, so he immediately gave the price.

This blood condensation essence soil Gu Xiaowu has also checked the information and asked about the relevant price from the outside store, the price of 500 million is not high but it is quite reasonable, after all, this thing is only an auxiliary material for cultivation for monks, not a panacea for improving cultivation. Xiao Wu immediately decided to sell to the auction house, and with the proof of these spirit stones, he should also be qualified to participate in the auction conference.

The young man was very satisfied with Gu Xiaowu's choice, and directly handed him 500,000 middle-grade spirit stones and a number plate with 1057 written on it, and explained to him that this number plate could only be used to participate in the auction on the first day, and he would not be able to participate in the next three days.

Xiao Wu had already inquired about this, and he didn't want to participate in the last three auctions, because only the first one was an auction of individual cultivation material treasures, and the next three were bidding between sects, and there were batches of resource auctions inside, and even the Lingshan Medicine Garden and even the secret realm would appear, which was not an auction that he could participate in at all.

Xiao Wu's purpose of coming here has been achieved, and he is ready to leave the auction building without delay, but when he arrived at the door, he suddenly thought of something, and then his face changed to a disappointed and depressed expression and left the auction building, and stopped an empty carriage on the side of the road and left.

The scene of his gloomy departure was being seen by the purple-clothed young man sitting in a teahouse opposite the auction building, it turned out that this Senior Brother Ma was not in a hurry to leave, but sat in the teahouse opposite and waited for Gu Xiaowu to come out, wanting to see if this junior brother had gained something. But just now I saw Gu Xiaowu's expression and didn't seem to get the number plate, but I can come here to try my luck, he definitely has treasure resources in his hands that he thinks can be worth a certain value, otherwise he won't come to the test, I didn't expect that this unknown Gu junior brother is not simple, do you want to make a shot at it once? At this moment, a woman wearing a white dress with a light veil came to the door of the auction building opposite, she stood in front of the auction building and glanced at the street and walked into the door, it seemed that she was also here to identify the material treasures, but this Senior Brother Ma didn't care if other people were carrying heavy treasures, after all, dealing with strange monks was much more dangerous than dealing with fellow disciples who knew the roots, and Gu Xiaowu had become one of his prey a long time ago, and he had already figured out his specific cultivation and strength, Even the place where he lives now has already been explored by him, otherwise he would not have drunk tea here with peace of mind, and he would have followed him secretly. It's just that this Gu Xiaowu is quite cautious, and he rarely goes to places with few people, and it is not easy to lure it out, and rashly looking for the past will startle the snake, so he can only wait for the opportunity.

After thinking clearly, Senior Brother Ma left the teahouse, and not long after he left, the woman in white walked out, glanced coldly at the teahouse opposite, and pondered the information he had just gotten. That person actually has a large amount of blood condensation essence soil, it should be a monk who came back from the Blood Sand Mountain Range, there is no doubt that he is a disciple of the Nine Yin Valley, but being able to take out so much blood condensation essence soil at one time does not seem to be an ordinary existence, if you want to know its specific identity, you have to start with the sneaky disciple of the Nine Yin Valley first.
