Chen Lin gazed at the lightning-struck wood in his hand, lost in thought.
The lightning-struck wood had already undergone a simple round of refining, giving it the shape of a flying sword.
It was about half a foot long and two fingers wide, with a scorched hue.
But for a flying sword to respond freely to its wielder, it needed to be inscribed with all sorts of spirit restrictions.
For instance, changing its size required a spirit restriction for enlargement and reduction; slicing through gold and jade required one that increased sharpness; making it sturdy required one that increased its solidity.
Without these supporting spirit restrictions, the body of a flying sword was nothing but an inert object.
"This makes no sense. This lightning-struck wood has clearly developed spiritual charm, so it should be perfectly capable of bearing spirit restrictions. Even if its material grade is too low to bear many, surely I should be able to inscribe at least one?"
Chen Lin muttered to himself.
"Could there be something wrong with my technique?"
He considered it, then immediately shook his head.
This was hardly his first time inscribing spirit restrictions on a Spirit Treasure. When refining the Xuanwu Shield, he had completed its spirit restrictions himself. Later, when repairing the Immortal Refining Gourd, he had also inscribed treasure restrictions. Both had gone smoothly.
This time, however, something unexpected had happened.
The moment a spirit restriction was fully inscribed, it dissipated, unable to remain within the flying sword.
Puzzled, Chen Lin summoned his destiny line into his mind with a thought, then began imagining himself inscribing a particular spirit restriction. But just as before, the line quickly lit up, perfectly intact. Never mind a break-it did not even have the slightest gap.
This indicated that, with his current abilities, inscribing
