Perhaps it's the soul strength continuously enhancing under the effect of the Banquet, originally five years ago, it took more than a month to learn the Six-Ring Water Dragon Technique at the entry-level. Now, five years later, Udi learns the Otherworld Teleportation Technique, also a Six-Ring Spell, reaching entry-level only takes half a month.
This learning speed, considering Udi's current Level 11 Caster level, is undoubtedly considered a genius.
It's estimated that the learning speed of many Master-level Mages above Level 15 for Six-Ring Spells is not as fast as Udi.
"I've reached entry-level; now for mastery and Returning to Truth; they only require time to wear down." Udi thought leisurely.
He didn't rush to immediately go to the Abyssal Plane using the newly learned Otherworld Teleportation Technique but continued to study and learn. After all, it's a cross-plane spell; the skill level must be high enough; if there's a mistake, it could cost a dragon's life...
