Conan: Science Cartoonist Kudo Yuji

"It's really not easy. After so many years, these six knives are once again in the hands of one person."

Inside the police station, old lady Washi Komiya stood with her hands behind her back, looking at Kudo Yuji who was about to take people out after dinner, and said to Washi Komiya Tsuntoki with some sigh.

"But this boy is quite playboy."

The two girls who had grabbed Kudo Yuji and reminded him out of concern were carefully instructing him, and everyone's eyes were focused on the little girl who was jumping up and down.

The long convoy drove out from the Hakodate Police Station, stretched into a long line on a road with few cars, and drove towards Goryokaku where pink cherry lights were flashing.

Sitting in the middle car, Kudo Yuji opened the wooden box in his arms and fiddled with the six star-edged knives with his fingers. Next to him was Conan, who was lying on the car door and observing the surroundings.

After arriving at Goryokaku, the first car in the convoy stopped where it was, and the following convoys split up one by one and began to surround the entire venue until all the cars stopped and their doors were opened.

Sitting in the car and watching a group of men in black begin to search Goryokaku, Kudo Yuuji picked up the walkie-talkie and reminded everyone not to forget to check the corners of the buildings and the bushes.

"We'll get off the bus once they confirm there's no bomb."

Kudo Yuji took out three knives from the wooden box and handed them to Conan, then held the three knives himself. He did not open the car door until the intercom rang four times to confirm that everything was correct. He found that his and Conan's car was located in the southeast corner of Goryokaku.

"It looks like the first car used as bait was fine, so it should be safe now."

Yuji looked around and quickly took Conan and the driver Gojo to the center of Goryokaku.

"Now we have to determine how to use these six knives to solve the riddle." Conan put the three knives in his arms on the ground, snatched the one in Yuji's arms, and pulled the six knives out of the sheaths one by one.

"It looks like there's no note or anything in the scabbard." Yuji clapped his hands, pointed at the scabbard and shouted, "Maybe it's the gap in the scabbard, break it open!"

"Ahem! Sir, this scabbard is a real antique." Gojo reminded helplessly: "This thing was collected by Keisaburo Axie, not made by him."

"The layout of the treasure and a series of plans were made by the unfortunate ancestor Kuroba Kaito, so we have to follow the Kuroba family's thinking." Yuji frowned.

"This is too difficult. His family has a standard brain problem. It's hereditary." Conan sighed: "We can't just take apart all the knives."

"Oh, you guys told me!" Wu Cheng pointed at the knife excitedly and shouted, "Take the knife apart! Take the knife apart!"

"Gojo-kun, this is the normal way of thinking." Kudo Yuuji looked at Gojo speechlessly: "We need to find Kuroba's thinking."

[No normal person would think of disassembling the swords!] Wu Cheng rolled his eyes and disassembled all the swords.

"Aha, you brothers are really geniuses. The riddle is hidden in the eye studs." Wucheng spread out the crescent-shaped eye studs, the five-pointed star and four other eye studs of different lengths in his hands.

"This doesn't make sense. How could the Kuroba family come up with such a common code? The previous code was obviously very worthy of a challenge!" Conan looked at his brother in disbelief, obviously he was extremely shocked.

"You have to forgive Mr. Kuroba." Yuji slapped his thigh with regret: "He could have been killed at any time, and there was always a beauty pestering him, and it was Keisaburo Axie who made the code paper after he escaped. Damn it."

"Are you guys regretting that the riddle is so simple?" Wu Cheng clenched his fists. "Collecting six knives is already quite difficult."

"I just felt that it started off well but ended badly. Maybe there will be some twists and turns in the end."

Yuji looked at Gojo meaningfully, but found that this guy was not looking at him, but holding six eye spikes in the reasoning position.

"Obviously the crescent eye pin is used to determine the night time, while the other eye pins are used to determine the location. We need to prepare a map with a similar scale to the eye pins, and then place it on top."

Yuji did not install the eye pins, but assembled the other parts: "This way we will know where to put the six knives in the right position to form a five-pointed star.

"That's easy."

Wu Cheng only took five minutes to do this. There was a printer and a computer in the car. After confirming that Hei Yu Youzhen's arrangement point was located one hundred meters south of the center, the three of them immediately began to continue to deduce the location of the treasure.

"Apparently, the marks and lines found on the sword guard are useful. Aim the lines at me." Yuji pointed at the blade with different angles and finally pointed to the northeast position.

"I should have thought of it earlier. The northeastern location, Mount Hakodate."

Kudo Yuuji put his hands on his hips and said, "The code paper can also lead to the northeast direction, which refers to the original shrine. I think the treasure should be buried there. The arrangement of the code paper should be something to ensure that there would be no accidents after the old shrine was burned down, but something is wrong."

"What's wrong?"

Conan frowned, and suddenly realized: "It was Washikomiya Tayu. She clearly said that the old shrine was where the extra knife was placed. Since the treasure is buried there, what is the knife for?"

"That sword is the way for the new shrine to identify the old shrine. Of course, the old shrine doesn't need it. Washikomiya Tayu is not telling the truth."

Yuji nodded: "She should be the eldest lady." (End of this chapter)
