In order to more accurately investigate whether there is any Abnormal Fire inside the Imperial Mausoleum, Chu Feng directly released the Nine Yang Strange Fire, a tiny blazing white flame the size of a candle appeared on Chu Feng's fingertip.
As his Nine Yang Strange Fire grew more powerful, the temperature of the flame continuously rose, and the color of the flame gradually changed.
Now it's at the sixth-grade, with the flame temperature around three thousand five hundred degrees. The color of the flame has changed from gold to white.
After releasing the Nine Yang Strange Fire outside his body, its perceptive abilities became stronger.
One could vaguely see the white flame at Chu Feng's fingertip, with a fire snake darting around its core. This is the spark of the Nine Yang Strange Fire.
After devouring two types of Abnormal Fire, it finally succeeded in taking form.
