Strongest Protagonist's Aura

Strongest Protagonist's Aura,

So, you're given a chance to reincarnate into another world, what special power would you choose?
Extreme mental capability? Immortal body? Power of creation?
Oh wait, you could choose the Strongest system? Or the Naruto system? Maybe an ultimate evolution system?
Hell no! Obviously you should choose the Strongest Protagonist aura because only that is truly invincible!
