Onyx & Pearl Dao Sword

Given to Wu Yu by Feng Xueya.

The left half of the sword was pure black, while the right half of the sword was pure white. It was a longsword immortal treasure. The sword was extremely broad and wide and seemed to weigh over 30,000 catties, and it possessed an Immortal Treasure Spirit Design. The design was emblazoned on the edge of the blade. Just by looking at it, one could feel its skyrending sword qi. It was clear that this sword was a lot more awesome than the Golden Bauble of Day.

It possesses a Heavenly Yin Formation and a Heavenly Yang Formation, a twin formation that allows its might to exude in all four directions. This could even be separated into two distinct blades, one black and one white. Both swords were narrow blades, sharp as thorns.
