What made it eerie was that the dark red sea of fire seemed frozen solid, without the slightest sign of movement.
Yet Su Tian could clearly hear the sound of surging flames beside his ears.
That discrepancy between sight and sound made the sea of fire seem profoundly uncanny.
Moreover, the heat radiating from the boundless sea of fire was so intense that even Su Tian had to draw on his Dou Zong strength to withstand it.
He even summoned the green lotus core flame to envelop his body, only then managing to keep the invisible, savage aura at bay.
"If I'm not mistaken, this sea of fire should be where the myriad beast spirit flame was born."
Su Tian surveyed his surroundings but found no trace of the myriad beast spirit flame.
His brows knitted, and a hint of confusion appeared in his eyes.
"Could it be hiding beneath this sea of fire?"
Lowering his head, Su Tian carefully examined the dark red flames before him, silently pondering the possibility.
He knew little about the Earth Flame in the depths of the Ancient Flame Cavern, so he would not lightly risk venturing into it himself.
Boom...
With his search proving fruitless, Su Tian considered for a moment before shattering a massive stone pillar beside him with a palm strike. Fragments flew in all directions, then plunged into the dark red sea of fire under his deliberate control.
Hiss, hiss, hiss...
The instant the rubble fell into the flames, it was incinerated into nothingness by the searing heat, without raising even a single splash.
At the sight, Su Tian's brows drew even tighter.
"Do I really have to go down there and investigate myself?"
In the deepest reaches of the Ancient Flame Cavern, there was no one besides Su Tian.
