The Spiritual Energy within the Formation was completely drained by the eighteen steles, and then... the Formation began to "crack crack crack" as sounds echoed... Eight stone pillars on the surface started showing cracks, which kept getting bigger and bigger...
"As expected, it works!" Gao Fei quickly retrieved the eighteen steles and then waited for the Formation to shatter.
"Crack crack crack..."
