As they try to enter the room where they found the password, the room starts to shake and the door to the place, which is a blueprint of the time machine, opens.There are many formulas in this outline. They take the draft to their lab immediately.

 David: My grandfather worked hard but couldn't complete the time machine. Mary: So let's get it done. Let's work hard, let's finish my grandfather's work.

Mary and David work hard, finish their time machine, and make their first trip to try it out. And  suddenly the gote opens. It has such a power that it takes David Mary in 1791.

Yes, but what are we going to do now

Do you have the time machine?

David looks around but he doesn' t  find it.And suddenly a baby dinosour Sinraptor comes to them. It has the time machine  on its hand. David and Mary are confused.

 The baby sinraptor steps on the time machine and teleports to the middle ages. David and Mary are fainted. The baby sinraptor looks around for a long time, then David and Mary begin to recover slowly. They start to look at each other, then the baby sinraptor.
