Chapter 821: Nameless Saber, Emperor-Grade Saber Intent! A Great Opportunity!

Chu Feng suddenly recalled a treasure he had seen when he was strolling in the study!

That saber!

The long saber that was extremely similar to the famous Nine Dragons Saber!

One had to know that the Nine Dragons Saber was the most important saber of the Nine Sabers God Emperor!

It had drunk the blood of countless experts since it was forged!

He wondered what connection the long saber that the Netherworld Emperor had with the Nine Sabers God Emperor.

Last time, Chu Feng had used this saber to practice the Art of the Nine-wave Saber, triggering the conditions set by the Netherworld Emperor and obtaining the Great Emperor's will!

At that time, Chu Feng could sense it.

Using this saber to execute the Art of the Nine-wave Saber seemed to be easier!

In fact, it was even more powerful!
