Perception guided the card ink flowing from the pen tip, inducing a wondrous fusion the instant it touched the blank card. His perception constantly shifted and oscillated, and those minute oscillations produced an extraordinarily rich variety of changes in the degree of fusion between the ink and the blank card.
Maintaining continuous, minute, high-frequency perception oscillations placed tremendous demands on a Card Crafter. Perception drained at an astonishing rate in this state. How to maintain those oscillations perfectly while minimizing perception expenditure was a problem every Advanced Card Maker had to face.
The higher a card's grade, the more complex the techniques it involved, and the greater the demands those techniques placed on perception.
Had any other Advanced Card Maker been beside Chen Mu, they would certainly have been astonished to discover that this mere four-star card involved a wealth of techniques beyond its grade. Those minute yet richly varied perception oscillations were advanced techniques typically used only in five-star cards.
Yet this was only a four-star card.
Ru Qiu possessed astonishing talent, but she was still too young. These advanced techniques were simply too difficult for her. That did not prevent her from understanding their significance, however. A four-star card actually contained so many advanced techniques! She was intensely curious about what marvels this card would be capable of.
Chen Mu, on the other hand, saw nothing particularly noteworthy about these techniques. His study of card crafting within the Vincent System dated back to when he had taught himself to make One-Star Illusion Cards. He lacked the necessary understanding of the Vincent System's card-crafting knowledge.
Ever since obtaining the Mysterious Card, the vast, profound knowledge within it had captured all his attention. Studying that knowledge alone consumed nearly all his energy. Where would he find the time to learn
