It took twelve days to accumulate enough points to upgrade the device. Hatta had stored 200 000 000 points in crystals, and everybody during this period came up with another 100 000 000. I got the rest.
It was late evening. When we finally had everything we needed. Everybody gathered in the city center as the news of me being able of opening a path to earth was spread among the people. I put my hand on the device and bought the fifth upgrade. The whole city started to shook, and people had trouble maintaining their balance. Several dozens fell down when an altar rose from the ground to elevate the sphere. That was it.
