As Bai Yi's current trump card, and also her own current race.
Bai Yi is most dedicated to witches.
The time spent on balancing genes is also the most.

Fortunately, for each race of witches, their racial characteristics can easily accommodate the original witch talents (superpowers).
It can even spare room to accommodate the metallization ability at the superpower level.
But as the ability to be permanently attached to witches, Bai Yi ultimately abandoned this method, putting the corresponding superpower organ inside the body, occupying a precious spot inside her for superpowers.
Then, by using the techniques learned during the separation of external limbs, she skillfully segments the superpower to ensure they don't interfere with each other.
