Inside the fog was a marsh that took up most of the area, and under the marsh was a giant cave. There were numerous tunnels connecting the giant cave to smaller caves and tunnels from those caves to others. The entire underground area was covered with big and small caves connected to each other.
Inside the largest cave, there were two youths dressed in the Red lotus sect's official disciple robes, both of them were peacefully meditating.
Buzzz...
"What is this?" The youths stopped meditating as they stood up and swiftly retreated hundreds of meters from the formation, they intently stared at the formation with piercing gazes.
The formation on the ground lit up with bright lights and sent a ripple through the air. Slowly, a black-haired youth came out and, the moment he appeared, he released a burst of overwhelming killing intent causing the youths to involuntarily take a few steps back.
