The Strongest Sword God System

I have seen Ximen Chuixue's sword, the loneliness coming from the west with one sword. I have seen the sword of Baiyun City Lord Ye Gucheng, which is as beautiful as a flying fairy from the sky. I have seen the sword demon Dugu Qiufei's sword, which is invincible in the world. This is an era of Dharma-ending, where immortals are no longer immortals and demons are no longer demons. The gods have been buried in the yellow sand, and the ancient swords are rotting in the residual wind. This is the best of times and the worst of times.
