The materials in the cabinet, the ones on top that look like snake skin, are indeed the inner layer of a snake demon's belly skin. Last time, I had the chance to acquire some materials with great difficulty. Some of the snake oil has been used, but the piece of snake skin, tempered by heavenly thunder, has been kept untouched.
Besides the snake skin, there are also pieces of pig skin. This pig skin is not ordinary, but specifically used in burn wards and is quite expensive.
These are the materials Big Sister Ye uses for restoration work. Since the revival of spiritual energy, it has been beneficial for Big Sister Ye, providing more materials with greater potential.
As for usage, she has no reservations because materials are meant to be used. Besides, when used for work, the expenses are covered by the organization.
