Stack four identical dice in figure 1 and put them on the wooden desktop, as shown in Figure 2. In Figure 2, the sum of the points of the face that cannot be seen from the periphery and above is _ _ _ _ _. As can be seen from the figure 1, adjacent to the point 1 are 2, 3, 4, 5,

So point 1 and point 6 are opposite faces.

Adjacent to five points are 1, 3, 4, 6,

So, 5 o'clock and 2 o'clock are two opposite faces.

So, 3 o'clock and 4 o'clock are two opposite faces.

The top invisible point is 3,

The second invisible point is 1, 6,

The third invisible point is 3, 4,

The bottom invisible points are 2, 5,

So 3+ 1+6+3+4+2+5 = 24.

So the answer is: 24.
