Upgrading the body multiplication potion is not too difficult for Wu Song to configure, but the process of upgrading is quite painful, although Wu Song's ability to resist blows is already very strong, but in the process of upgrading, Wu Song was twice stunned by the severe pain that was enough to radiate to every cell in his body, and after some tossing that made him exhausted, Wu Song fell into a deep sleep.

This sleep lasted until noon the next day, and when he woke up, Wu Song still felt extremely sore, if it was normal, Wu Song would probably recuperate for two days, but now, Wu Song had no time to waste rest, this guy simply ate something, and then went to the yellow trading hall to find Velica.

"Sir, why do I have such a strange feeling when I see you today?"

After the two met, Wu Song didn't expect Velica to come up with such a sentence, he was stunned, and then asked with a faint smile, "Is it?" What's so weird? ”

"I don't know." Velica shook her head very sincerely and said, "I just feel that you are not the same as yesterday, I can't put into words, your smile still looks so amiable, but I seem to be more afraid to see your smiling face than yesterday, I can't tell why, I hope you don't mind." ”

"I'm not a mutant creature that eats people, am I as scary as you say?" Wu Song smiled bitterly, but secretly admired this little guy's strong perception ability, at the moment when the two first came into contact, Wu Song almost instinctively used an auxiliary device to observe Velica, and found that Velica was just an ordinary person who couldn't use the power of his soul, but he was such an ordinary person, but he found a lot of subtle changes that thieves couldn't find!

Although Wu Song is purely from the appearance of the form, there is no change from yesterday, but Wu Song himself is quite clear, his momentum is completely different from yesterday, after forcibly multiplying the body overnight and raising two levels one after another, Wu Song's physique has undergone earth-shaking changes, his basic ability can be said to have made a qualitative leap overnight, and after the huge change in strength, Wu Song has not been able to effectively control the aura emitted by the changed body for the time being, Although he tried his best to hide it, there was still a slight change in his aura compared to yesterday, but this change was difficult for people who did not have a strong perception ability to observe, and what he didn't expect was that an ordinary child like Velica, who was not even a spirit master, noticed the difference.

"This kid's perception ability seems to be innate, damn it, it seems that he is a good seedling who was born to be a thief, if he is cultivated, he should be a pretty good guy." After feeling Velica's powerful perceptual ability, Wu Song had a kind of love for talent for the first time, and he actually had an urge to envelop Velica under his command.

As a thief, Wu Song knows very well how important perception is for a thief, thieves are melee light armor professions, which means that in battle, they can't enhance their security by controlling the distance between them and the target like hunter mages, and they can't protect themselves with thick armor like warriors and knights, and in addition to the security in the battle, thieves often have to play the role of pathfinders in the team, although thieves can be invisible, But stealth isn't a panacea.

In many cases, even if the thief is invisible, his own safety will be greatly threatened, at this time, perception ability is one of the most important means for thieves to save their lives, but perception of this thing in addition to acquired training, talent is also extremely important, and although Xiao Velica is not a thief, his perception is undoubtedly extremely powerful, which makes Comrade Xiao Wu, a guy who has a strong perception by relying on cheats, feel more jealous and wooing in his heart. However, this feeling only existed in his mind for a moment, and then it was replaced by something else.

"Let's go, we're going to the black trading floor today, and I think we'll be busy in the next few days." Wu Song sighed with emotion, and then went to the black trading hall under the leadership of Little Verica.

The situation in the black trading hall is as chaotic as the yellow trading hall, and in the center of the hall is also a crowd of people who buy and sell freely, but compared with the yellow trading hall, the number of traders here has obviously decreased, in the yellow trading hall, Wu Song's rough estimate is that the number of traders in it is only less than 20,000, and it is more than 10,000 people who are dead here.

Wu Song followed the routine of visiting the yellow trading hall yesterday to learn about the market of the items in these stores in each store, and in the process of looking at the price, Wu Song further understood the differences between the two trading venues.

On the list of items for sale listed by merchants on the black trading floor, most of the items for sale are more than those listed by merchants in the yellow trading hall, but the proportion of the number of materials at the same level is far less than that of the yellow trading floor.

The number of eighty-level materials is completely disproportionate to the seventy-level materials, and the proportion of seventy-level materials in the yellow trading hall is quite large, accounting for about one-third of the total proportion of materials sold by merchants, that is to say, if the merchants in the yellow trading hall sell thirty kinds of materials, about ten of them are seventy-level materials, and the proportion in the black trading hall is seriously reduced, and the merchants sell thirty kinds of materials, of which there are five kinds of materials above eighty. Most of the others are just some relatively rare sixty or seventy level materials, and there is almost no phenomenon of skipping the sale of them in the black trading floor at this stage.

Yesterday, when he walked around the yellow trading hall, he could occasionally see merchants selling materials above level eighty, but in the black trading hall, he didn't see any shops selling materials above level ninety, which made Wu Song clearly realize that if he wanted to collect all the materials needed to upgrade the eighth-level body multiplication, he was afraid that he would have to go to the silver trading hall. And realizing this, Wu Song couldn't help but be a little grateful to the bewitching appraiser Qin Jing before, if she hadn't suggested that Wu Song should get a high-end pass, Wu Song might have exchanged Lingma black gold crystals for black or even yellow passes.
