The power of an Empyrean Zinger plus the Major Treasure of Attribute and a 10-Life Stage cultivation was Inala's original endgame build. Theoretically, it would have taken him 220 years to achieve it and his entire journey would be to hasten it as soon as possible so that by the time the Fourth Major Disaster starts, he'll be ready.
This was something he had conceptualised while reading Sumatra Chronicles for six years, a result of endless daydreaming sessions for the world he came to love. When he was brought to Sumatra Continent, Inala already had a ready path to tread upon.
That was why he started to focus on a skillset that made best use of his Empyrean Zinger powers, from puppetry to painting. Heck, even the primary reason he picked art during his shut-in years on Earth was simply to make fanart of Sumatra, because he was enamoured by it.
