Regarding the choice between the Silver Upgrade Fire Source and 10 ounces of Dominant True Spirit, this actually falls within reason.
(PS: Does the measurement unit ounce feel a bit off?)
Excluding the three Golden Sanctuary Components, the highest valued is indeed this Silver Upgrade Fire Source.
Fire Seed Oddities are already rare, and among them, those that can be transformed into Upgrade Fire Sources are even fewer. Coupled with the Silver Legend quality, it's no exaggeration to say, the value of a portion of Silver Upgrade Fire Source is nearly not much less than that of a Golden Sanctuary Wondrous Oddity.
And the 10 ounces of Dominant True Spirit is an essential item for components that wish to be enhanced to Seventh Rank or above in the future.
Although the Heavenly Ruins Cang Qiong ascended to Fourth Rank just sixty or seventy years ago, after decades of expansion wars, the warship's foundation has actually caught up.
