Gongsun Yan is a rather miserable Son of Destiny.
Being the son of destiny is pretty good. Heaven has given him super talents, so many adventures, super beautiful girls, etc.
Such a smooth road to becoming a god is all well-arranged by Heaven.
But why is it said to be tragic? Because he finally completed the ninth life of karma, and on the eve of becoming a god in this last life, his soul was contaminated by a few alien souls that came from unknown sources, and was judged as an unqualified defective product by heaven.
But the first life of the Conferred God has been started, and it cannot stop at will, so Tiandao has no choice but to tear down the east wall and mend the west wall, and capture a complete soul from another world to destroy the first life of the Son of Destiny.
