Perhaps eager to taste Otto's promised wine sooner, Dain had been staying in the Land of the Soaring Dragon these past few days without leaving.

Out of boredom, he even visited Sofia and Moray's magic research lab.

During this time, Sofia and her team had been researching how to increase the reload speed of the torsion ballista.

When Dain heard this, he immediately burst into laughter.

According to him, such a war weapon made by humans would be considered a large pile of junk in the dwarf kingdom.

Moray originally wanted to retort, but his mouth was soon shut by the cruel reality.

Dain personally rode his griffin to the Sulfur Mountains, followed by Moray with a look of disbelief and the spectators Sofia.

Under his guidance, the Black Iron Dwarves staying in the Sulfur Mountains took only two days to build a full-metal war chariot, something like a bed crossbow.
