[After summoning the Little Dragon and his spirit rings, Yu Xiaogang activated his fourth spirit ring.]
[Under everyone's expectant gaze, the fourth spirit ring began to glow.]
[In an instant, a flood of information entered Yu Xiaogang's mind, and the details of his Fourth Spirit Ability became perfectly clear.]
["Excellent!"]
[After understanding the ability, Yu Xiaogang clenched his fist excitedly.]
[His Fourth Spirit Ability was exactly what he had hoped for—the Light-Dark Conversion inherited from the Radiant Evernight Beast.]
[As he activated the skill, the Little Dragon transformed into a ball of light and merged back into Yu Xiaogang's body. Brilliant golden light enveloped him completely.]
[Then, before everyone's eyes, the golden radiance gradually darkened from the bottom upward until it became a deep, pitch-black aura.]
[Only after the entire light cocoon had transformed into darkness did the process finally stop.]
[Moments later, the darkness slowly dispersed, revealing Yu Xiaogang once again.]
[His hair, which had turned golden after his Martial Soul evolved, had now returned to black.]
[However, this black was even deeper and darker than before.]
[When Yu Xiaogang opened his eyes, everyone was startled.]
[His once-golden pupils had turned crimson—identical to the color of a 100,000-year soul ring.]
[Cold...]
[Sinister...]
[Mysterious...]
[Every characteristic associated with the Dark Attribute naturally radiated from him, making it seem as though he had always possessed a Dark-Attribute Martial Soul.]
["Phew... I didn't expect a single transformation to consume so much spirit power."]
[Yu Xiaogang let out a long breath before looking toward his father and the others.]
[Only then did he notice the astonished expressions on their faces.]
["What's wrong?"]
["Did something happen to me?"]
[He quickly took a mirror out of his storage soul tool.]
[The moment he looked into it, even he was stunned.]
["My eyes... turned red?"]
[He widened his eyes and carefully examined his reflection.]
[Originally, his pupils had been black.]
[After evolving into the Light Attribute, they had become golden.]
[Now, following the conversion to the Dark Attribute, they had transformed once again.]
[But that raised a question.]
[Shouldn't Dark Attribute users have black eyes?]
[Why were his crimson instead?]
[Yu Xiaogang voiced his confusion.]
[Unfortunately, no one present could answer him.]
[In the end, he could only suppress his curiosity.]
["Forget it."]
["It's only a change in eye color anyway."]
["It doesn't seem to have any special abilities."]
["That said..."]
["This dark form looks incredible."]
["Black hair, crimson eyes..."]
["Combined with this naturally cold aura..."]
["Not bad."]
["Very, very good."]
[Holding the mirror from different angles, Yu Xiaogang admired himself repeatedly.]
[He had only one thought.]
[It looked unbelievably cool!]
[He continued admiring himself until Yu Yuanzhen finally coughed several times.]
[Only then did Yu Xiaogang awkwardly put the mirror away.]
["Ahem..."]
["I never expected changing attributes would also change my appearance."]
["That's really interesting."]
["Oh, right..."]
["Little Dragon!"]
[Suddenly remembering his companion, Yu Xiaogang immediately became excited again.]
[If his own appearance had changed this much...]
[Then the Little Dragon, whose existence was even more closely tied to its attribute, should have changed even more dramatically.]
[Without hesitation, Yu Xiaogang summoned it once again.]
[As spirit power surged, dark energy condensed before him, forming what looked like a miniature black hole.]
[The moment everyone looked at it, they felt an irresistible pulling force.]
[It wasn't merely a physical attraction.]
[Even their souls seemed to be drawn toward that endless darkness.]
["What terrifying power..."]
[The Grand Elder couldn't help but sigh in amazement.]
[Such overwhelming attraction could only exist when the Dark Attribute had reached an extraordinarily high level.]
[In other words...]
[Yu Xiaogang's Light-Dark Conversion truly allowed him to switch between the Light and Dark Attributes without any loss of power.]
["If that's the case..."]
["Once Xiaogang matures, then aside from having only nine spirit rings instead of eighteen..."]
["He can practically be regarded as a Spirit Master with twin Martial Souls."]
[Yu Yuanzhen clenched his fist excitedly.]
[Between his own son and Bibi Dong—the two future prodigies destined to dominate the Douluo Continent—he naturally hoped his son would become the stronger of the two.]
[In Yu Yuanzhen's eyes, Yu Xiaogang had always been the more outstanding genius.]
[However...]
[Bibi Dong possessed an enormous advantage.]
[A twin Martial Soul meant the possibility of attaching eighteen spirit rings.]
[That was something Yu Xiaogang's single Martial Soul simply couldn't match.]
[Although cultivating twin Martial Souls carried the danger of body collapse...]
[Who could guarantee that the problem would never be solved?]
[Placing all your hopes on your opponent failing was the height of foolishness.]
[If Bibi Dong eventually solved that issue...]
[She could equip her second Martial Soul with nine more spirit rings.]
[At the very least, nine Ten-Thousand-Year Soul Rings.]
[If she were patient enough...]
[Even several 100,000-Year Soul Rings wouldn't be impossible.]
[By that point...]
[Yu Yuanzhen couldn't imagine anyone on the Douluo Continent consistently defeating her, except perhaps his future self after becoming a god.]
[Of course, personally bullying someone his son's age was beneath him.]
[Unless the Blue Lightning Tyrant Dragon Clan faced destruction...]
[He would never interfere.]
[That was why he sincerely hoped Yu Xiaogang could surpass conventional limits.]
[Light-Dark Conversion had already eliminated the weakness of relying on a single attribute.]
[Combined with Yu Xiaogang's profound understanding of self-created spirit abilities...]
[He would never lack powerful techniques.]
[The only thing he still needed was stronger base attributes.]
[As long as those continued improving...]
[Even Bibi Dong's twin Martial Souls wouldn't necessarily surpass him.]
["I hope Xiaogang can achieve it..."]
[Yu Yuanzhen silently prayed.]
[Meanwhile, under everyone's watchful eyes, the black-hole-like dark energy gradually solidified.]
[The next instant...]
[The black sphere exploded.]
[A tiny black dragon appeared before everyone.]
[Its once golden scales had transformed into metallic black.]
[The deep color seemed capable of swallowing everything around it.]
[When it opened its eyes...]
[A pair of crimson pupils identical to Yu Xiaogang's stared back at them.]
[The same cold, mysterious aura instantly filled the surroundings.]
[Unfortunately...]
["Awoo~! n(≧▽≦)n"]
[The Little Dragon's adorable cry instantly shattered the cool atmosphere.]
[Everyone, who had been worried that its personality might change after gaining the Dark Attribute, couldn't help rolling their eyes.]
[They had worried for absolutely nothing.]
[With its mouth closed, it looked like an awe-inspiring dragon of darkness.]
[But the moment it opened its mouth...]
[The entire atmosphere completely fell apart.]
