Where are the black beads?

Taiji Gate: When you come to the alley, you can find the stage for the performance. Forget it, go on, find the fortune-telling place and find a ruby on the table.

Stage: Go back to the stage and interact with the objects here as shown by the arrows in the figure below. After Redjade was installed, the plot triggered and a man jumped down from the upstairs!

Eyeball: It turns out that the person who jumped off the building is our colleague! Close to the body, you can pick up his eyeballs. Finally, use this eyeball to open the Tai Chi door.
