The Battle Soul Blood Banner was indeed incomparably sensitive to blood energy.
Like a magnifying glass, it instantly amplified Ye Zhen's perception of the blood energy fluctuations beyond the crimson light screen by a hundredfold, a thousandfold. The previously incomparably vague fluctuations immediately became clear within Ye Zhen's Spiritual Sense.
Yet what he sensed filled Ye Zhen with boundless horror.
He was horrified to the very core.
Within the crimson light screen, countless streams of blood energy surged and flowed without cease.
At first, they appeared chaotic and disordered, but the longer he sensed them, the clearer they became.
These blood energy fluctuations seemed to be moving along invisible veins, and gradually, even their direction became clear.
The countless streams of blood energy wound their way down from above along those invisible veins, eventually converging beneath the crimson light screen.
Below the crimson light screen seemed to lie an enormous blood pool, like a heart, ceaselessly gathering the blood energy flowing in from every direction.
The blood energy contained within that blood pool—or perhaps that heart—was boundless beyond measure. Even a rough estimate of its quantity made Ye Zhen shudder.
With Ye Zhen's cultivation, before that oceanic mass of blood energy, he felt like a speck of dust beneath heaven and earth, a firefly before the bright moon.
All of this made Ye Zhen's scalp tingle with terror.
Why could this place gather such an immense quantity of blood energy?
What was the purpose of gathering such an immense quantity of blood energy?
More deadly still, if such an ocean of blood energy erupted, Ye Zhen did not even dare imagine the consequences.
If that happened, let alone the North Sea Heavenly Wave Army, even the entire Blood River Fortress would be reduced to ashes in an instant.
