Once the Serpents reached the Reversal Plains, there were two tails connected to each other at two ends -- one, the Gold Serpent, the other, Gong Gong. "Seems That There Has Been A Perversion Here," spake the Light God, Teus. "I Will Correct This Properly." Through a simple inversion process, once the serpent Gong Gong withdrew from Valparaiso back into the Reversal Plains, the cargo of the $yndicate which was borne unto him would be taken back into MaTeus to carry them to the next location.
Likewise, the Gold Serpent's tail which was still attached to the Reversal Plains would be sucked back into it and inverted into Gong Gong, allowing for Gong Gong to pass through the barrier that was the Reversal Plains over the land without becoming inverted, itself and returning back to the Lawless Land without passing through the Reversal Plains. The Gold Serpent, however, inverted on itself from the tail up after being sucked back inside and, in exchange for Gong Gong's leaving, was slipped back to Dr. Money, from whence it came as an equivalent exchange.
From here on, MaTeus would once again be carrying the cargo of the $yndicate off toward the next path instead of the King Keaton and his dragon, Gong Gong.
