[Seeing Yu Xiaogang impatiently flip through the ancient books as soon as the deal was done, how could Flender not realize that he had been tricked?]
[The other party's desire for the ancient books in his hands far exceeded his original expectations.]
[It was likely that even if he had asked for more than the fifty gold coins earlier, the other party would have been determined to get them.]
["You, you, you..."]
[Having figured this out, Flender pointed at Yu Xiaogang with a trembling finger. His furious appearance amused the other merchants watching from the side.]
["Hahaha, Flender, even a kid like you has a day where your eyes fail you?"]
["You cheat others all day long; how does it feel to be cheated by someone else today?"]
["Hahahaha, interesting, truly too interesting! I think I'll remember this scene for decades!"]
["That kid isn't simple either. He looks young, but he played Flender like a fiddle."]
["Tsk tsk tsk, one can only say Flender's level is still too shallow. If it were me, I couldn't possibly have been tricked."]
["You? Give me a break. Who was it that got played by Flender last year and sold him a valuable treasure as scrap?"]
["..."]
[The sound of everyone's mockery caused Flender's face to gradually turn red.]
[Thinking of himself, Flender had been in this Treasure Market for several years. Aside from losing some money at the very beginning due to being unfamiliar with the market, he had basically never misjudged anything afterward, thanks to the characteristics of his Spirit.]
[He didn't expect to be played today.]
[How could he endure this?]
["Kid, you..."]
[Before Flender could finish his sentence, Yu Xiaogang turned around and prepared to leave.]
[As he walked, Yu Xiaogang used Flender's own words against him.]
["The rules of the Treasure Market are: once the money and goods are cleared, no refunds are given even if you bought the wrong thing."]
["Correspondingly, once the money and goods are cleared, the transaction cannot be canceled even if you sold the wrong thing."]
["These are the rules on your side!"]
[His voice wasn't loud, but it was precisely this calm tone that made Flender's face flush even hotter.]
[Sensing the gazes of those around him waiting for a show, he barely held back from sending two Wind Blades at the spectators.]
[Flender was certainly unwilling to just let Yu Xiaogang leave like this.]
[So he stepped forward quickly and pressed a palm onto Yu Xiaogang's shoulder, intending to say something more.]
[However, it was this single touch that caused both Flender and Yu Xiaogang's expressions to change simultaneously.]
[Yu Xiaogang didn't even care to look at the books he had just acquired; he stared fixedly at Flender's hand as a feeling of disbelief filled his heart.]
[How is this possible?]
[Through the contact with Flender, Yu Xiaogang perceived an extremely special sensation.]
[It was as if he were craving Flender's power.]
[Of course, it wasn't he who was craving it, but the little Dragon inside his body that was craving this power.]
[It was as if, through this power, the little Dragon could become even stronger.]
[And this feeling was not the first time Yu Xiaogang had felt it.]
[Back when the little Dragon completed its true Martial Soul Awakening and performed Spirit Possession with him, Yu Xiaogang had felt a similar sensation upon touching the little Dragon.]
[Except that compared to the feeling between himself and the little Dragon, the current sensation wasn't as intense—it was like comparing a river to a small stream, completely on a different Rank.]
[But Yu Xiaogang would absolutely not misremember that unique sensation.]
[It was precisely because of that sensation that he could determine that the Spirit Possession between himself and the little Dragon was a type of Martial Soul Fusion Skill.]
[Because in the records of various factions across the Douluo Continent, when both parties of a Martial Soul Fusion Skill touch each other, this special feeling exists.]
[Of course, having this feeling didn't mean the Martial Soul Fusion Skill could be successfully executed.]
[After all, a Martial Soul Fusion Skill required not only compatibility but also mutual trust.]
[Given the current relationship between Yu Xiaogang and Flender, even if they truly had a Martial Soul Fusion Skill, it would be impossible for them to trust each other.]
["You..."]
[Yu Xiaogang wanted to say something, but as if startled by his words, Flender's eyes suddenly widened.]
[After pondering for less than a second, Flender dropped his body and sat on the ground, hugging Yu Xiaogang's leg.]
["Brother, you are definitely my long-lost brother!"]
["Brother, you must take me with you!!"]
[Flender's sudden action not only stunned Yu Xiaogang but also the crowd that had been watching the show.]
[Wait, how did they suddenly become long-lost brothers?]
[Did they miss something?]
[Ignoring the scrutiny and contempt from the crowd, Flender was now determined to cling tightly to Yu Xiaogang's leg.]
[This person before him wasn't old but was generous with money and even carried a storage soul tool—something commoners could never come into contact with.]
[Clearly, this was a young master from a great Family.]
[Although Flender didn't know exactly what that feeling just now was about, there were only a few possibilities.]
[The most likely one was a Martial Soul Fusion Skill.]
[Although he didn't know why he and this complete stranger had a Martial Soul Fusion Skill, if he didn't seize such a good opportunity, eighteen generations of his ancestors probably wouldn't forgive him.]
[So, after grabbing Yu Xiaogang's leg, Flender had no intention of letting go.]
[Looking at Flender, who was hugging his leg and refusing to let go for dear life, Yu Xiaogang's face immediately broke into black lines.]
[Good grief, where is your dignity?]
[A guy clearly older than me is acting like a child even younger than me, hugging my leg and throwing a tantrum.]
[You really don't want any face at all, do you?]
[If Flender could hear Yu Xiaogang's words right now, he would probably nod frantically.]
[Don't want it, don't want it. What's the use of that thing? It's not something you can eat or drink.]
["Let go of me!"]
["No, I won't, I won't! Good brother, my dear brother!"]
["Who is your brother? Let go of me!"]
["No way! If you want me to let go, you have to admit you are my biological brother from another mother!"]
["You..."]
[Yu Xiaogang was at a loss looking at Flender, who refused to let go.]
[At this moment, Yu Xiaogang realized for the first time the weight of the saying: 'A shameless person is invincible under heaven.']
["Xiaogang, what on earth is going on?"]
[Watching Flender pester Yu Xiaogang from the side, Bibi Dong almost couldn't help but laugh out loud.]
["The situation is a bit complicated."]
[Yu Xiaogang didn't know what to say either.]
[Randomly meeting a passerby only to find out they share a Martial Soul Fusion Skill—this kind of thing was just too absurd.]
[Are Martial Soul Fusion Skills something so easily come by?]
[And to think that a shameless, unscrupulous merchant like Flender actually satisfied the conditions for a Martial Soul Fusion Skill with him—Spirit compatibility, Soul resonance...]
[Good grief, how would others look at him in the future?]
