I Level the Nine Provinces with One Sword

He is a sword.

The immortal sword that everyone in the world wants to possess!

In the scramble for it, he was claimed by the most powerful cultivator of the age. From then on, he had a master of his own. His master was aloof and silent, and had long been in love with a young man who was the apple of his eye. The master always guarded him quietly.

He gradually cultivated a human form and, before he knew it, fell in love with that beloved young man, too.

The young man was as gentle and refined as jade, his smile like the stars, and his tender charm was impossible to resist.

Then his master went mad... and locked him, the sword, in a frigid pool for a thousand years.

Who does his master really love?
