The sudden change of events here, neither Chu Liang nor Xu Ziyang had anticipated.
At that time, Chu Liang was diligently harvesting Thunder Cloud Seeds with the Demon-slaying Sword, achieving much success. He had already mined a stone seed the size of a fist. He didn't know how much this piece would yield after refining, nor knew how much was needed to craft the Talisman Heavenly Plate, so he never stopped.
Even though his current form was merely an external avatar, he still brought the Demon-slaying Sword with him.
Because Chu Liang's real body was hidden on Shu Mountain, he could manipulate the Purple Green Double Swords within the mountain gate. Regardless, the Purple Green Double Swords were of a far superior grade.
Hence, the Demon-slaying Sword could only be of use outside the mountain gate.
If he always hesitated to take it out for fear of losing it, then the expensive Demon-slaying Sword that he had bought would be useless.
