Gu Changhuai also glanced at Mo Hua.
Among them, Mo Hua was the best at Formations.
Although Gu Changhuai was a Golden Core Cultivator, he was not as skilled in Formations as Mo Hua.
Mo Hua immediately straightened up:
"Let me take a look..."
He touched the door frame, with his back to Gu Changhuai, his eyes deep, using Tricky Calculation to amplify and deduce the Formation Patterns inside the carriage.
Gu Changhuai's expression stiffened; he sensed that the aura on Mo Hua's body had changed, becoming somewhat profound and eerie, but he was gradually getting used to it, so he said nothing.
After a moment, Mo Hua concluded:
"There's a Door Lock Array on the carriage, and a self-destruct array, it's a Compound Formation..."
Following the deduction of the Formation Patterns and the flow of Spiritual Power, he found the "keyhole" in the right lower corner of the carriage door, among some carved wooden Patterns.
This hole merged with the wood Patterns, making it hard to detect.
