Blood Luo Hall's headquarters had been built on an island, surrounded on all sides by seawater.
However, this was no ordinary seawater, but a blood-red sea.
This sea was known as the Blood Sea, and the island where Blood Luo Hall's headquarters stood was called Blood Island.
Su Mo and Cai Yun flew into the Blood Sea, and the overwhelming stench of blood nearly made them vomit.
"Could this really be a sea formed from blood?" Su Mo's face was filled with astonishment. The bloody aura within this sea was incredibly dense, as though it were entirely made of martial artists' blood.
"I don't know!" Cai Yun shook her head.
After pondering briefly, Su Mo took out the Billion Demonic Sword.
"Demonic Spirit, can you absorb the bloody aura in this Blood Sea?" Su Mo asked the Demonic Spirit within the sword.
"Gaga ga!!"
The moment the demonic sword appeared, it immediately let out a strange laugh brimming with excitement.
"Of course I can absorb it. Such dense bloody aura is enough to restore thirty percent of my strength!" the Demonic Spirit said excitedly.
"Good. Then absorb as much as you like!" Su Mo flicked his arm, and the Billion Demonic Sword immediately shot out, plunging into the Blood Sea in an instant.
Su Mo did not leave. He stood in the air, waiting for the demonic sword to finish absorbing.
Seeing this, Cai Yun also stopped and waited for Su Mo.
After the Billion Demonic Sword entered the Blood Sea, the waters below immediately began to churn violently, raising towering waves.
The waves rolled and quickly formed a massive vortex. The vortex grew larger and larger, spreading outward in every direction at tremendous speed.
Endless bloody aura converged toward the vortex, its dense crimson tint staining even the heavens
