Those words were originally uttered by Huo Sining in a moment of urgency, but after saying them, her mind suddenly became clear like a flash of inspiration.
That's right, isn't Watanabe Yasu going to participate in the New Year Festival with that teabowl? She has every chance to swap it back.
Watanabe Yasu must treasure that bowl dearly, usually locking it in a safe or storing it in a bank. She had no chance to get close to it, but he's going to attend the New Year Festival, so he will definitely bring it out. This person loves fame and fortune so much, this bowl could bring him immense prestige and benefits, he definitely won't keep it a secret.
Huo Sining has the Invisibility Skill, and during the New Year Festival, she can slip into Meiji Shrine. As long as Watanabe Yasu takes out that Secret-Color Porcelain Teabowl for exhibition, Huo Sining can swap the bowl back without anyone suspecting a thing.
