Wei Wuyin was reminded of his time in the Scarlet Solaris Sect. When he first arrived, he was a pot of boiling feelings and stressful air. After his older brother had sacrificed his life to ensure his survival, witnessing the slaughtering of his clansmen, and losing everything important to him in a short period, he would've done anything for the sake of strength.
ANYTHING!!!
He wholeheartedly devoted himself to cultivation, fueled by the dreams of vicious revenge and endless nightmares of repeating events. He forged his own path, grasped every opportunity for power, and struggled. But, he never lost himself. His older brother had instilled into him a sense of unyielding principles and morals, and considering he only lived because of those very principles and morals, he would never forsake them.
