Experimenting with the Dead.

After Danzel forcefully made Shiro drink the blood of the ice trolls while being careful not to drown her in blood in the process, he did notice Shiro's overall status improving and her health recovering.

But her growth didn't seem to stop.

He already let her "drink" 1 liter of blood and he was worried that any more would be worse than good.

All that he could do now was watch how her own body was eating from the inside to fuel the body's growth. And all that blood that she gave her only recovered around 1500 health.

He tried to tell her to cast her healing magic, but with no success.

So he waited while watching her health drop lower and lower.

Though also her attributes were increasing.

The most noticeable change from this growth, was the fact that Shiro was gaining height, her hair was becoming longer with even her nails growing.

"It's as if she is growing older..." Danzel stated as he watched quite helplessly.
