The Five Worlds

"Alone!" You give the answer.
The book the dwarf holding suddenly shines, the golden light shines between you and the dwarf, and the dwarf smiled, " you are right! Thank you! You are my son's hero! Now, please follow me to my home and enjoy a wonderful night."
You follow the dwarf. One step and the next, you slowly see a blue house not far away, and it becomes gigantic as you move closer. When you stand in front of the house, you see blue pointed roof, white wall that looks so clean, golden light shines like diamond. It is a castle.
A lady dwarf comes out, next to her is a boy dwarf.
"Father, did you find the answer for me?" Says the little boy.
"Yes! My dear, say hi to your hero!" the dwarf pushes you in front of the little boy.
"Thank you, sir! The question is too hard for me and my parents to answer. Please enjoy the dinner with us!" Says the little boy.
You accept the invitation.
In the middle of the table is a chocolate cake. There are four seats around the table and there is a glass of red wine and a fried steak in front of each seat.
You sit down, and have a taste of the steak. The meat is chewy and the fat melts in your tongue. The steak is so delicious.
Suddenly, you feel dizzy. You look at the dwarves. They are smiling at you. You smile back. The next second, their faces change, their eyes turn so big and the noses disappear. They open their month and their red teeth appear. Monsters! They are monsters!
You try to run away but you can hardly move.
You see a knife in front of you and you can try to fight with them using the knife, or you will just give up and be killed. What will you do?
