When we arrive at the end of the corridor Adam approaches the box, his gaze locked to the box, touches the surface of the buttons and exclaims: "l finally found you". From the pocket of his shirt he extracts a magnetic card that inserts in the slot then presses the strange buttons.

I remember exactly the sequence: first the "GORILLA", second the "OCTOPUS" on the middle button, then the "VOLATILE" and finally the "LIZARD" on the middle button again. After a few moments a kind of mechanism is activated, the wall at the end of the corridor opens and as if by magic a new room appears. A bright light pierces my eyes! Slowly I begin to see the inside of the room; it is a laboratory larger and more technological than those already seen here in the bunker. There are some large empty incubators connected to other machines. Adam is focused on looking for something in particular.

I take the opportunity to write in my diary everything that happened today and is happening right now, then I tell him: "I want answers, right here and right now!". Adam begins to explain: "It all started here; many years ago in this laboratory were carried out experiments that aimed at our genetic modification in order to make us stronger and to improve our immunity to this cursed gas. Experiments combined our DNA with other animal ones, but something went wrong! I'm here to find the solution to this problem."

I hear movement and voices coming from the entrance of the bunker.

I'm going to see!
