One day in the sky, a year on the ground.
A year on Water Blue Planet, over 3600 years have passed on Sangze Star.
3600 years, seas have turned into mulberry fields, stars have shifted, trees withered and regrown, regrown and withered again, and beasts in the forest have been born and perished in waves.
All things alternate, the old is succeeded by the new.
Only the towering tree covering the entire Sangze Star has stood steadfast, not only avoiding decay and rot but growing more vibrant, covering the sky and blocking out the sun.
When it first took root, it could only cover half of Sangze Star. But now, its vast canopy completely obscures the whole of Sangze Star. The majestic trunk pierces the atmosphere, appearing in outer space, continuously absorbing the mixed and vigorous energy from space.
This tree is naturally the World Tree.
