Villain: the Son of Destiny Wants to Stick with Me?

It's not a holy mother, it's not sentimental, it doesn't follow the plot, it kills the children of destiny at will, and it has many female protagonists. When awakening at the beginning and being approached by the Son of Destiny, the system becomes stronger. A grandpa-type son of luck? Ye Fan! Your grandpa must have a big problem! He wants to harm you! I am your best friend! How could I harm you? Fortunately, I have a magical skill here! This evil-proofing sword technique is just for you! Hi, we are all brothers, you're welcome. Buddha the son of destiny? Master, I invite you to... Play, you're welcome! Huh? Are you a child of fate, the type of orphan from the upper world? So do you think your father should choose you or your mother? The Dragon King's son-in-law? I like my sister! Still my sweetheart! You can't be angry about your uncle's test or anything like that.
