With a stern shout from Qin Zheng, the once silent and solemn underground space was suddenly filled with harsh cries of battle.
A blanket of murderous aura instantly enveloped the entire area.
Adventurers with weaker strength were hit by this aura, causing blood to spill from the corners of their mouth - their injuries were non-trivial. Even the stronger adventurers were taken aback, their skin crawling with goosebumps.
Every wall of the underground space was filled with complex, ancient formation patterns. Numerous carvings on the walls depicted countless soldiers engaged in fierce battle.
As Qin Zheng yelled, activity sparked within the ancient formation patterns etched on the walls. Faint lights began to glow, flowing like silver threads. These threads quickly expanded, intertwining and eventually forming bright lines of light.
