If one really wants to engrave the Golden Armor Spirit Array onto their body, at the very least, their cultivation level must break through to the Noble Qi Realm, where they can externalize Spiritual Power. This makes it easier to set up the spirit array.
Using a spiritual pen to draw the Golden Armor Spirit Array is still not as precise and perfect as directly controlling one's own Spiritual Power to form the array.
The thought of breaking through to the Noble Qi Realm constantly circulated in Lu Yu's mind, hard to extinguish.
Thinking about real-world matters, Lu Yu felt it was necessary to accelerate the enhancement of his power. If the Golden Armor Spirit Array could truly be engraved onto his skin and ensure it can always remain active, his safety in real life would definitely improve drastically.
