Even now, the liquid capital that Gaven has at his disposal amounts to five million at most—this refers only to cash, excluding fixed assets or unsold goods, such as the Regeneration Ring Series. Up to now, Gaven has only sold the fast-healing series publicly; the more advanced versions are either consumed internally or given away as gifts, while the rest remain in his inventory. These items do not depreciate and are sometimes even more liquid than money. They'll only be considered for liquidation when the cash flow becomes truly strained.
The speed at which Gaven generates income these days is indeed incomparable to before, so much so that he doesn't have time to meticulously calculate how much profit his enterprises earn daily. Suffice to say, the number is extremely high—it's no exaggeration to say he's literally earning gold daily.
However, he spends even faster than he earns.
