Dr. daji and Bart d. are about to begin a blacksmith's competition. The two boys choose the same metal for the competition, and the two boys argue about which metal to choose. Dr. Daji says that he's already won the competition and that he can't compete anymore. He says that if he and his younger brother hold the titles, they'll both get the prize money. But his senior sister says that she's the one who's going to give the title to her brother. She says that the competition is for her, so she'll be the one to give it to her little brother. After all, he says, he'll still be your little brother, so he won't be able to steal the title from her. He tells his little brother to trust him, and that's how the competition begins. After the first round, both boys adjust their breathing and enter the "state of forging" . They're both in the same state of perception, so they can see the same thing at the exact same time. This is the first time that Dr. Duji has ever seen two kids in such a state.
