Using Source Stones to inscribe Dao Patterns was, to some extent, as extravagant as using large banknotes to cut paper window flowers on Earth when it was still called Sea Blue Star. However, in Guding's storage space now, Source Stones were the most abundant item, while all other materials were limited.
A Source Stone, only the size of a thumb, posed a great challenge for ordinary people to inscribe upon, but for beings like Guding, size was not an issue. With his current strength, he could easily inscribe on a bacterium at the nanoscale, let alone a thumb-sized Source Stone.
However, the difficulty in inscribing Dao Patterns lied in the fact that if one didn't master the corresponding Dao Patterns, the inscribed lines would automatically deform. It felt like someone suddenly slapped the hand holding the pen while drawing, ruining the painstaking artwork.
