It's Not Easy to Be the Protagonist

Lin Tian traveled to a foreign land and obtained [the moment of life and death]. After resurrection, he will not lose all the abilities he obtained last time, but he will lose part of his memory about his death, which may be about the person or thing he assassinated. He belongs to a family with the most abundant resources in the whole continent. As the eldest son of the patriarch, the family treats him very well, but they only don't let him touch things like cultivation. There seem to be many people in the shadows staring at his position. The assassinations again and again make him stronger, but he just can't be sure whether the person he is revenged against now is the person who killed him in the first place.
