The saintly light on Yan Kongming's arm flickered. His arm shook and he sent three blue-green metal plates flying out. They formed three beams of blue light that flew toward Zhang Ruochen.
The metal plates seemed to be translucent. Dense patterns appeared on the surface. They looked ancient and beautiful.
Boom!
Boom!
Boom!
Three explosions erupted in a row.
The three metal plates cracked apart and beams of blue runes flew out. They interwove and transformed into three Sixth Grade Battle Formations, enveloping Zhang Ruochen's formation.
The three Sixth Grade Battle Formations were the Skyheart Great Ape Formation, Xuan Ice Formation, and the Divine Wind and Thunder Formation. They could all damage a Half-Saint formation and were Yan Kongming's last trump cards.
