Zhang Ruochen spoke confidently, and said, "It was recorded in the ancient books that the Timespace Viburnum came from the Searock Bastion where it grew in the Archean mines.

It meant that the Timespace Viburnum emerged from the Searock Bastion and grew on the Archean mine. In the beginning, it was as white as jade. After the Yuanhui Tribulation, it became black and into two colors. Within 500 miles of the light that it emits, three months were day and three months will be night, and half a year will become one day.
