Now that the navigation umbrella has been unlocked, the time machine is much more powerful. The unlocked time machine will be able to recognize the time of day, which will make it easier for you to track your progress. The navigation umbrella also prevents you from getting lost in the labyrinth of time and space, which is why it's so important to unlock it. Now that he's unlocked the umbrella, he can go outside and explore the world around him. There's lots of new technology around him, and he can't wait to explore it. He's even more excited to explore the underground river, which has a tunnel that leads up to the top of the mountain. The tunnel is connected to a biological research area, where he can use a vaccine to cure silver sand. He can then run off with the rest of the team, and the scientist will have nothing to do with him. The only thing he can think of to do is to get the vaccine out of the tunnel and run away.
