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."
"This Southerner Formation is used for navigation."
"The carriage will follow the navigation of the Yuan Magnetic Southerner Formation and take us to our destination on its own..."
Mo Hua said logically and clearly.
The expressions of Gu Changhuai and his two companions slightly shifted, and then they were amazed in their hearts.
This is what formations are, encompassing the myriad phenomena of the world.
This is also what Formation Masters are, using formations to comprehend and control various kinds of knowledge and abilities...
"Then, can this vehicle move now?" Gu Changhuai asked with a slightly solemn expression.
Mo Hua said: "This is a new composite formation system. It will take me some time to study it a bit."
"Alright." Gu Changhuai nodded.
After that, the three of them held their breath and kept absolutely silent, lest they disturbed Mo Hua.
Mo Hua, on the other hand, concentrated on studying this composite formation that integrates the Yuan Magnetic Southerner Formation and mechanical driving formations.
Mo Hua was barely familiar with the Yuan Magnetic Southerner Formation.
But he hadn’t really come into contact with mechanical driving formations before.
However, he had studied the First Grade Twelve Patterns, the Ultimate Technique of the Minor Hidden Spirit Sect—the Soul Pivot Ultimate Formation.
The Soul Pivot Ultimate Formation involves formation sequences, spiritual thread manipulation, and shares a resemblance with mechanical techniques.
In South Yue City, Mo Hua had even used the Soul Pivot Ultimate Formation to create some labor-saving, mineral-transporting "Wooden Ox and Flowing Horses" for the impoverished mining cultivators.
So, he understood the basic principles of the formation.
Time was limited, and he didn’t need to master it thoroughly. He just needed to reactivate the formation.
The formation before his eyes was dim and lifeless, evidently out of order.
Mo Hua pondered carefully.
In about an hour, his eyes brightened as he gradually grasped some understanding.
This mechanical composite formation, like the carriage door, is opened with a shared key.
But the formation on the door had been resolved by Mo Hua, and the lock was broken; thus, the control entrance of this mechanical composite formation was effectively destroyed as well.
With the "entrance" intervened gone, the formation could not be opened naturally, the formation eye could not be energized, and the mechanical driving formation failed, leaving the carriage immobile.
"In that case, the structure of the Formation Pivot has to be altered, severing the original entrance, externally connecting open-close formation patterns, and establishing a Spirit Gathering Array to serve as the formation eye, embedding it into the composite formation to power the existing mechanical formation..."
Mo Hua muttered to himself, speaking words that Gu Changhuai and the others could not understand at all.
Then Mo Hua took out pen and ink, beginning to reconstruct the formation step by step according to his own ideas.
Gu Changhuai and his companions watched intently.
Yet, they had no idea what they were actually watching...
About 30 minutes later, Mo Hua finally completed drawing the formation, and after checking it over once more, he couldn’t help but breathe a sigh of relief.
"It should be about right..."
Mo Hua reached into his Storage Bag to take out Spirit Stones.
Halfway through taking them out, he silently pocketed his own Spirit Stones again, instead reaching out to Gu Changhuai:
"Uncle Gu, we need Spirit Stones."
This was business, and the Spirit Stones used should appropriately be reimbursed.
Gu Changhuai was not stingy, and he took out a Storage Bag and tossed it directly to Mo Hua.
Mo Hua took the Storage Bag, extracting the Spirit Stones and crushing them, placing them on the Spirit Gathering Array to let it absorb the spiritual power, serving as the formation eye to empower the mechanical formation.
The Spirit Gathering Array absorbed the spiritual power, glowing with a blue sheen.
Mo Hua concentrated his thoughts, activating the formation through the interface he had constructed.
A stream of pure spiritual power flowed from the Spirit Gathering Array into the mechanical composite formation built into the carriage.
Then the carriage shuddered, and with a wobble, it began to move on its own.
The few of them quickly held onto the carriage.
