The white mouse, Bai Yi, began to tremble.
Its fur started to change from pure white to patches of gray.
Under the skin, lumps the size of fingernails began to form.
In just over ten seconds, the mouse which had just been completely normal, had grown lumps all over its back.
All of its hair turned completely gray, and its eyes gradually reddened. Its fangs became more numerous and dense.
The most exaggerated change was its spine.
The entire spine began to bend and arch upwards, with some parts even poking out of the back, revealing sharp grayish-white bone spurs.
What surprised Li Chengyi even more was Bai Yi's size.
After the mutation, it had become twice the size it was before!
Previously, it was only the size of a palm, but now, it had reached the size of a small kitten.
Hiss!
Bai Yi's temperament seemed to have undergone a big change as well.
It opened its mouth to reveal its sharp teeth and made a threatening hissing sound at Li Chengyi.
'Interesting...'
