It was a massive scale excorcism, triggered by mantra from a book. We hunt down the location from ebay. Then went to the room to setup the necessary procedure like carving a writing to a piece of skin like material as per the instruction from Keanu.

There is massive scale of undead around, and to get rid of of it we need to burn all of them out. In order to distract them from us, Keanu ordered a massive tanker and attract them there, some of them that are left over and try to come to the apartment is ushered away using a holy water.
I had to locked the door out, and some of them still trying to force their way in from the window, that’s when the holy water comes handy.
After the mantra on the skin was ready we would spell it out then all a massive fire will be triggered and burned all the undead.
