I'm Just an Ordinary Person with S-Rank Strength and Speed

(Post-apocalyptic zombies + strong heroine + no romance in the main story + max-level expert back in the beginner's village + small ensemble cast)

Ellie, an interstellar general, accidentally transmigrated into a post-apocalyptic novel and became a cannon-fodder supporting female character. Although she awakened two abilities, among all the strange powers in this world, such as elemental manipulation, teleportation, and spatial abilities, Ellie's strength and speed seemed utterly ordinary.

As expected, the original heroine awakened a healing ability. People no longer had to worry about mutating after being bitten by zombies. Everyone rejoiced, seeing healers as the hope of ending the apocalypse and believing that the end of the era was near.

However,

Ellie remembered that this book had a bad ending.

Mutations were happening at a pace beyond all reason, and the enemy deployed its forces as if it had a mind of its own. As casualties mounted, humanity finally encountered a game-changing variable of its own...

At first, people thought that healing abilities would be enough to wipe out the zombies.

But in the end, Ellie became the light of hope for humanity.

Ellie looked at the starry-eyed young woman.

The original heroine, who was supposed to build the strongest team, how did she become my little fangirl?

During a joint mission between bases, the person in charge saw Ellie's abilities, strength and speed, and thought, “What a great pair of abilities for moving supplies!” With a wave of their hand, they assigned her to ordinary logistics duty.

But then the defensive line collapsed. A gigantic shadow swung its limbs, and no one could stop it. Just as everyone was on the verge of despair, a silver-white streak of sword light cut across the sky, and the shadow slowly fell.

The crowd was about to cheer when they saw the yellow cloth marking the hero as a member of logistics, tied around her left arm.

Everyone scratched their heads: ??? This is logistics?

The person in charge stared at the roster in shock. Beside Ellie's name, it clearly said: S-rank!
