Yan Zhaoge had once witnessed the strange phenomenon of twin rainbows, one inside and one outside as they lined up perpendicularly, slicing across the horizon together.
While those two rainbows had both had seven colours, their order was the exact opposite, one moving from red to violet while the other moved from violet to red.
As Yan Zhaoge knew, that had been due to the refraction and dispersion of sunlight and water vapour. While it was rare, it could still be considered normal.
However, the Ten Character Heavenly Rainbow before them consisted of two rainbows which were exactly the same intersecting amidst the horizon, one moving from east to west while the other moved from south to north, meeting along their paths.
It was the first time witnessing such a sight for even Yan Zhaoge as he could not help but click his tongue in wonder.
