Lucian immediately went with Eira by using a horse carriage to the Nuclear Dragon Labyrinth first according to Evan's orders.
"Aw, aw... this hurts a little." After they left, the effects of his drastically reduced 60% mana began to be felt. His body felt squeezed and made him limp. He didn't expect that giving a surname to a high level demon like Lucian would consume almost 60% of his mana.
Like Luna's previous warning, he would spend a lot of mana to give a surname to a demon that was already at a high class. And risk dying if the MP needed exceeds his MP capacity.
'Gosh, if it consumes that much MP how can I evolve both Lucia and Bluebell at once before the quest time runs out!' Fortunately, the use of his mana did not exceed the capacity he had and that made Evan relieved because his worries about the risks that would be experienced could be anticipated with his mana which had increased dramatically.
