Calamity Of a Zombie Girl

It's a hot summer day in a university campus where most students are out of school for summer vacation. Five students from the same dorm, sneak into the library storage to look for some treasure. They find two sets of female antique mummies from Italy around the age of 14-20 years old.
One of the members, Sayaka rips open one of the mummy and takes out a stone which is called "stone of life". This was a special stone created by humans, empowering the mummies to have super strength and eternal life.
Having stolen their "stone of life", the two mummy girl wake up and become zombies after 100 years in order to get the stone back in a bloody gruesome way, smashing their heads and eating their flesh for power.
The only way for the students to get out is to somehow find a way to kill the zombie girls.
Will they be able to survive?
