The Family Soul Skills?

Sword Douluo Chen Xin had brought Ning Fengzhi along to watch the spectacle. But when he saw the middle-aged man standing on the giant sword, long-buried memories came flooding back. He dropped Ning Fengzhi in front of Bibi Dong, flew up to Extinction Douluo Chen Jue, and asked in a choked voice, "Second Uncle, is that you?"

Extinction Douluo Chen Jue looked at Sword Douluo Chen Xin. At his words, he seemed dazed. The coldness in his eyes, forged through years of killing, gave way to age and tenderness. "Little Chen Xin, you still remember me?" he asked, his voice trembling.

"Second Uncle, how did you become an Evil Soul Master?" Sword Douluo Chen Xin asked, his eyes full of confusion.

"Because I was lonely. After my Martial Soul awakened and mutated, I had no friends outside the family. Later, when I wandered Jianghu, the demonic energy in my Demon Sword Martial Soul erupted. Without your grandfather or father beside me to suppress it, I lost my mind and killed many innocent people. I became everyone's enemy. I kept running, but the more the demonic energy eroded my mind, the more I craved killing. I killed more and more people and made enemies of ever greater powers.

"Spirit Hall wouldn't let me go. The great families wouldn't let me go. Even little adventurer groups wouldn't let me go. The more people I killed, the more Demonic Qi gathered in my Demon Sword Martial Soul."

Extinction Douluo Chen Jue smiled bleakly. "Your grandfather held off countless pursuers for me. In the end, a Titled Douluo from Spirit Hall killed him. I even went to Spirit City to take revenge, but I failed. I escaped that battle using the blood-escape art innate to my Demon Sword, and it damaged my very foundation.
