Heaven Burning Flames

Ao Lei became more and more excited and said firmly, "The Heaven Burning Flames only exists in ancient records, but it is said that it is an immortal-grade cultivation technique. Back then, I was fortunate enough to witness these flames inside an ancient ruin, and it felt like I had descended into the fiery depths of hell!"

After hearing Ao Lei's words, everyone was taken aback and in disbelief.

However, when they looked at the ball of flames, it truly felt like it had emerged from the depths of hell. If they were struck by it, they would probably have already been incinerated!

Also…

Immortal-grade cultivation technique?

Were their ears deceiving them?

Was Feng Xiyun's Heaven Burning Flames technique not a heaven-grade cultivation technique? Had Ye Xuan somehow improved it?

How utterly heaven-defying!
