Leon did not swagger out of the Vampire Mansion; he specifically waited to leave invisibly using the Gathering Form and Scattering Energy spell until he was far away from the Vampire Mansion. It was only in a deserted place that he finally revealed his form.
This still wasn't the end.
Leon remembered that not all the Vampire Derivatives had been killed inside the mansion—there was absolutely no way to transform into a Dragon and move freely inside the mansion; relying solely on his human form, it was indeed not easy to kill them—considering that someone might remember his appearance to prevent any unforeseen complications, he prepared to change his image.
Leon's Transformation Skill was different from altering his own body, which could completely change his appearance, including height, weight, facial details, voice, hair, skin color, and so on, not limited to gender. Even more so, growing sharp claws, fangs, spikes, or horns was not a problem at all.
