The work is about the altar of the Mayan period. With the weakening of religious beliefs and the invasion of human wars, the altar gradually declined and was inaccessible. As an explorer, you will gradually explore this place, unveil the veil of history, and explore the traces of civilization. The work constructs two scenes of day and night respectively. During the day, everything seems to be normal, but at night, it will give birth to a gloomy and evil atmosphere.
