Leon decided to visit Tiamat in Avernus, but he wasn't planning to go immediately. It was known that Tiamat was not easy to deal with, so he had to make thorough preparations.
Since he wasn't planning to upgrade the Volcanic Island from a Cave Heaven Blessed Land to a Heavenly Realm for the time being, the massive wealth he had accumulated could be used to purchase alchemy materials, refine Heavenly Immortal Pills, and further enhance his battle strength.
