Mysterious box

If you were asked to choose between living in the world alone or living with your mortal enemy, e normal person would immediately choose to live alone, After spending some time alone in this room I realized that whoever chooses to live alone in a world without his mortal enemy would regret his choice; since a human can't live alone.

Even though I hated that mad scientist when I heard his footsteps outside the room instead of feeling annoyed I was rather anticipating him.

The mad scientist came into the room while carrying the huge heavy box, He bent down to put the box on the floor I was about to ask him, What was that box. but he stopped me with his hands and said while panting like a dog, "let's commence the testing."

"but first let me take my breath" he continued.

After a while when he caught his breath he said, "Its time to see if you are the person we have data on from the past life or not."

I became curious about what could be in the box that would confirm that. so I asked him,

"W-what is in that box?"

He replied, "You will find out right now"

He put his hand into his lab coat pocket and picked out a box cutter then he opened the box and put the box cutter back into his pocket.

He squatted down and started searching for something inside the box then suddenly he grabbed a knife out of the box.

It was too big to be considered an ordinary kitchen knife, it seemed more like butcher's instead, It was noticeable that its blade was sharpened as it's tip was shining and for some reason, The mad scientist was smiling while holding the knife up, It seemed that he was about to finish me off so I took a few steps backward and said nervously,

"W-what are you doing?"

The mad scientist said: "How do you feel about this situation?"

I said furiously, "How would you feel when a stranger you barely know hold a knife with a creepy smile facing you?"

"of course I am scared!" I continued

The mad scientist sighed and said, "seems like this isn't gonna work."

Then he tossed the knife back to the box and started looking for something else inside the box I got curious about what he is looking for, So I went ahead to beak at what is inside the box and I found out that it's full of murdering tools from knives to pickaxe to guns and poisons as well.

I pulled back quickly and tripped onto the floor and shouted, "WHAT ARE YOU TRYING TO PROVE HERE YOU CRAZY SCIENTIST"

Then the mad scientist stopped searching inside the box and stood up?

He said, "looks like this isn't going to work we have to move on to the next phase."
