Conan Edogawa, still frightened, couldn't help but shout:

"Are you trying to kill us? Please be serious."

"Don't make things difficult for me. This is a huge vault built by Sanshui Kichiemon! There are bound to be mistakes. You'd better stay away from the wooden door and the tile with a different color. I think that's a trap too."

The two people who didn't dare to walk around stood still and stared at the big safe vigilantly. After Kaito Kidd opened the big safe, they found that it was Suzuki Jirokichi's beloved dog Lupin who stayed inside.

"Woof woof!"

Seeing Lupin knock Conan to the ground, Fujiwara Yu looked at Kaito Kid, who had returned to his original form, and raised his eyebrows and said:

"Kaito Kidd, do you remember what I said?"

"Hmm? Oh...I know. I won't do that again."

"Then you should leave quickly. Inspector Nakamori should be back soon."

Kaito Kid adjusted his white hat and suddenly remembered that Uncle Nakamori had invited him to dinner at Aoko's house tonight. He thought for a moment, holding his chin, and then extended the invitation:

"Mr. Yingsi, why don't you come with me?"

"Huh? Why would Brother Ying Si go with a thief like you!" Edogawa Conan suddenly realized that something was wrong. Could it be that Brother Ying Si already knew the true identity of Kaito Kid? Thinking of this, he hurriedly asked: "Brother Ying Si, do you know who he is?!"

"Yeah, but it's boring to reveal the answer directly. You'd better figure it out yourself." Fujiwara Yu patted Conan's round head with a smile. He looked at Kaito Kid and nodded, indicating that he should follow him.

"Well, little detective, see you later."

Kaito Kid smiled and saluted as a gentleman, then dropped a flash bomb and disappeared.

Also disappearing was Sosuke Takagi.
