In the great hall.
As Lin Chen obtained the first key, the remaining floating flames suddenly surged, transforming into a wave of fire that poured down the hall. Sensing the power of this fire wave, many martial artists' expressions changed slightly, and almost without hesitation, they retreated towards the hall's exit.
This fire wave was stronger than the one at the hall's entrance before; they couldn't withstand it.
Of course, some were unwilling to retreat and prepared to resist the flames, but the final result was that they turned to ashes.
After this wave, the number of martial artists in the hall had decreased by a hundred.
In the entire great hall, Lin Chen was the only one unaffected by the flame flow. This time, it wasn't because of his strength, but because he held a key. When the flame wave appeared, the key emitted a glow, forming a halo that blocked the flame wave.
The flame wave came quickly and disappeared just as fast.
