Mo Hua said: "It's the internal driving formation of the carriage."
Seeing that Gu Changhuai didn't quite understand, Mo Hua explained:
"This carriage has a frame but no reins, which I found peculiar before. Now that I see the formation, it makes sense. This carriage looks like a carriage, but it's not actually a 'horse' carriage."
"This vehicle doesn't rely on horses to pull it. Instead, it uses mechanical techniques, embedding a composite formation inside to drive the vehicle forward."
"And the formation hidden beneath this wooden board is precisely the embedded set of the mechanical driving composite formation in this carriage."
Gu Changhuai pondered for a moment, a thought striking him, "Does that mean..."
"Yes." Mo Hua nodded, "Once the composite formation is activated and the spiritual power flows, it will automatically drive the mechanism to move the carriage forward."
"Moreover, this composite formation also has an embedded Yuan Magnetic Southerner Formation."
