The Boss at the Top of the Tower

Sorry, revising the story gave me a new idea, so I'm putting this one aside for now.

The premise was already quite similar to a Sentinel-Guide story, so I thought I might as well start a Sentinel-Guide story instead.

"She Marked N S-Rank Sentinels"

Blurb:

Xia Yi is the youngest S-rank Guide in the White Tower. On the battlefield, she can temporarily mark multiple Sentinels and command their legions to fight in coordination. She can also deeply mark several Sentinels, making them submit at her feet and swear absolute loyalty.

The Sentinels of the Fortress deeply fear her. They call her a witch and list her as their most dangerous enemy.

The supreme commander personally signed her death warrant: kill her immediately upon finding her, with no mercy.

Years later, he ate his words.

At the peace talks between the White Tower and the Fortress, the man who had vowed to kill her personally proposed a condition: to become her last exclusive Sentinel.

Xia Yi was utterly baffled.

How had a soft, adorable girl like her, who spent every day dealing with trivial chores, become a witch feared by the enemy nation's Sentinels?

Her ultimate dream was simply to curl up in her own Sentinel's arms and enjoy a lovely autumn dream.

But... why were her exclusive Sentinels becoming more and more numerous?

Blurb:

As one of the top powerhouses of the apocalypse, Lin Ruoxi should have become a founding hero. Instead, she transmigrated into a world a hundred years in the future and was handed a somewhat dark, mildly coercive script.

From the start: a captive of the resistance + an experimental subject of a deranged researcher + a purifier serving high-ranking ability users

Lin Ruoxi rubbed her forehead. How could she turn this around?

Her trump cards: youthful beauty + S-rank purification ability + the potential to copy others' abilities through deep physical contact

In the darkness, she had to calm the high-ranking ability user on the verge of going berserk.

Cold chains wound around her wrists, and a beastlike aura bore down on her.

She calmly negotiated: "Trust me. The power of purification is most effective when both parties are enjoying themselves."

Because she successfully "soothed" the Federation's number-one commander, she was no longer an experimental subject known only by a number. Instead, the government hired her as an officially appointed purifier.

In the eyes of the high-ranking ability users she soothed,

she was a beautiful, frail princess imprisoned in a tall tower,

until one day she blew the tower up.

The world was thrown into chaos.

The men who had tried to conquer her became her knights.

And so began the queen's story.

It starts with dark confinement and ends at the top of the world.
