Bleeds

Yu Yuanshan, the nephew of the Clan leader of the Yu Family, had a challenging upbringing. From a young age, he was subjected to distress and bullying. The constant conflict and animosity between his parents made him feel helpless and overwhelmed. Enduring bullying himself, he gained a deep understanding of the harsh realities of the world - where only those with exceptional qualities are truly respected, and others are treated as inferior.
His unorthodox beliefs spurred him to great success: he fortuitously gained control of the Origin Martial System. With a fervent ambition for supremacy, he endeavors to transcend earthly and celestial boundaries, ascending to the pinnacle of existence!
(extra note: he is kinda messed up.. plus his whole family was destroyed so is further alone )
