Fantasy: Supporting Role System? I Can't Be the Protagonist Anymore

Traveling through another world, I wanted to show off my ambitions, but... "Ding! The supporting role system is at your service." "Now randomly assign the protagonist you need to follow." What! Am I a supporting role? Opposite there are jade trees facing the wind, and the young master with the protagonist's breath is staring at my sister behind me. A familiar feeling arises spontaneously. "Please choose to absorb the proportion of the protagonist's luck." "Please choose the type of magic weapon to share with the protagonist." However, it's great to be a supporting character. No, the protagonist died again... In the fight for the protagonist, if you miss the slightest moment, you will be killed thousands of miles away. The wife is too dangerous, but the supporting role is safe. "Ding! Please choose the next protagonist." Wait, isn't this the saint from the Wanshou Eight Immortals Palace in front of you? !
