Travel Through Time to Become an Orphan, and Befriend the Child of Destiny

Is it wrong to travel from an orphan to an orphan? Is this a novel world? I seem to be the template for the protagonist, the young master coming down the mountain. What? Is there an immortal being reincarnated? What. Is there a Dragon King Palace Master? Are there so many children of luck? Did I make a mistake? Then let's have a good relationship with the Children of Destiny... However, are all so-called children of destiny really worthy of being friends? So what if you have a system? What right do you have to decide the life and death of others at will? I, Chu Feng, slaughtered the Son of Destiny today!
