you are the only person who accepted this challenge. The challenge will consist of putting a tight corset on you (which will be locked with a padlock (of course the man will have the key to the padlock)), tying your wrists really tight behind your back, tying your arms tightly so they are pressed against your body, tying your knees and ankles tightly, putting a tight blindfold on your eyes and locking it with a small padlock, putting an oxygen mask on your face (tightly fastened with straps so that it fits your face well) connected with a long tube to a large oxygen tank, the room in which you will be locked will slowly fill with water (but you will be able to breathe through the oxygen mask). You came to the building where you will be doing it. The man told you that if you survive a week (7 days) you will get 21 million.
