From the Start, I Raise a Thunder-Slaying Dragon with Roar of Time

[A slight golden finger + pure romance with one female lead + face-slapping] I transmigrated into Douluo Dalu and became the useless Yu Xiaogang, awakening Luo Sanpao, a Trash Martial Soul that can only fart! My clansmen mock me, and my sect looks down on me. Everyone sees me as a disgrace to the Blue Lightning Tyrant Dragon Clan. Faced with endless insults and bullying, I simply smile and pay them no mind. Because I’m not the useless Yu Xiaogang. I’ve always believed that there are no useless Martial Souls, only useless Soul Masters! I understand Douluo Dalu better than this so-called master of theory! In my hands, even the trashiest Mutated Martial Soul can shine with a brilliance that will astonish the continent! So what if cultivating soul power is slow? I’ll simply skip ordinary soul power and cultivate the "Annihilating Thunder Dragon God Art" bestowed by the System! I’ll make my body a furnace, nurture the lord of a thousand thunders, and refine the Annihilating Divine Thunder! With my physique, I’ll shake heaven and earth. With thunder arts, I’ll command the sky! Who says I’m useless? Why not have a nice chat with the Annihilating Dragon God inside me? This time, I’ll be Yu Xiaogang! I’m going to win Bibi Dong over and become the ruler of Spirit Hall!
