The sickly iron fist beauty in Harry Potter

Traveled through Harry Potter and became Harry's older cousin——
No, now it's little cousin Dolly.
But Dolly was not shocked for even a moment by the crossing, she had to face a big problem.
She awakened the golden finger that is essential for time travelers.
Good news, this system allows her to become a wizard and enjoy an extraordinary life.
Bad news, this cheat code requires kryptonian.
[Paying blood, organs, or even lifespan can be exchanged for skill points that strengthen all attributes and items. ]
【Clearly marked, fair trade, no deception. 】
Looking at the tempting reward and feeling the desire for magic in her heart, Dolly clicked the system's shutdown button without hesitation.
Magic is good, but it is not as important as your own life.
After all, as Harry's family member, Dolly is not unqualified to visit Hogwarts.
Instead of wasting your life learning magic, it is better to seize the trend of the times and enjoy life.
However, just as the system was about to shut down, Dolly suddenly thought of something.
"Um, Sister System, can I get the snowflake cotton stored in my body?"
