It seems that the Heart of Molten Fire is a rather important place for the Dwarf Kingdom.
Even if disguised as a dwarf, Lis could not actively ask to enter the Heart of Molten Fire in a short time.
Otherwise, if this identity was exposed, Lis would never have another chance to enter the Heart of Molten Fire.
After a while, when the Dwarf Kingdom still hasn't found that "Sun Elf Legend," and lets its guard down, it will be the best opportunity for Lis.
So during this time, Lis plans to stay at the Iron Hammer Workshop and hone his forging techniques.
Dwarves do not much like leaving their skills and insights on paper; they prefer to teach through actual forging.
Therefore, Lis didn't find many forging-related books in the Iron Hammer Workshop, but various peculiar forging items allowed him to appreciate the excellent craftsmanship of the Dwarf Masters.
Having seen a lot, Lis felt a bit eager.
With plenty of ideas in his mind, Lis was quite impatient to try them out.
