Chapter 688: The Name of the White Rainbow Sword King Is Destined to Be Invincible for an Era!

This Sword Marquis of Bai Hong's sword-Dao talent was already terrifyingly strong to an unheard-of degree.

Now, having gained the guidance of Ancestor Tian Jian, it was simply adding wings to a tiger; his insight into the sword Dao naturally advanced a thousand miles in a single day!

Thinking of this, Nie Wushuang glanced at the Elder of the Tian Jian Sect before him.

His lips trembled slightly as he said:
