After rebirth, my sister and I exchanged superpowers

When the apocalypse descended, my sister and I activated our latent powers.

Lily, without hesitation, chose the flashy and powerful lightning ability. However, unable to endure hardship, she ultimately wasted her talent and barely survived in the base.

I, on the other hand, relied on my seemingly useless healing ability to amass vast resources and became sought after by various base leaders.

Out of kindness, I saved Lily, but she, consumed by jealousy, led me into a horde of zombies.

Given a second chance, this time she snatched the healing ability first.
