The headquarters of the Cold-blood Hall was built on an island surrounded by sea water.
However, the waters surrounding it was not ordinary sea water, but red sea water.
This sea was called the blood sea, and the island the headquarters was on was called the blood island.
Su Mo and Cai Yun flew towards the blood sea. The air was filled with the scent of blood, making the two nauseated.
"This sea isn't really made of blood is it?" Su Mo asked in surprise. The blood Qi in the sea was especially strong, as if it was made of blood from martial artists.
"I'm not sure!" Cai Yun shook her head.
After some deliberation, Su Mo retrieved his Billion Demonic Sword.
"Demonic Spirit, can you absorb the blood Qi in this blood sea?" Su Mo asked the Demonic Spirit in the Demonic Sword.
"Hehehe!"
The Demonic Sword laughed sinisterly as soon as it appeared, its laughter was filled with excitement.
