*Sigh* "Ester must have told you what Lupa told her... " Vincent picked the smartphone from her hand and revealed the last battery in the world.
"This is the power source to make the smartphone work. We were in a crisis when Ester was about to die from her cold magic running rampant. So I sacrificed all batteries but this one to keep her warm. " Vincent placed the battery in Sakura's hand and continued, "The smartphone can work again if you could one day replicate a battery with the best crafting class in the world."
Sakura's eyes showed the burning determination of creating an object from another world. "I always made weapons and armor. I sometimes carved wood sculptures to keep my finger coordination at the highest level of accuracy possible."
Sakura stood up and raised the battery to cover the sun. She stared at the battery with great interest and thought how nice it would be to stop doing strength-requiring jobs such as blacksmithing.
