Conan: The Mechanic

"Above us is a hot spring?" Tadao asked in surprise. "how come..."

Others were also surprised.

"How come it's not a hot spring?" Conan asked back.

"What do you mean?" Tadao was even more surprised.

"First of all, in terms of hints, this treasure is comparable to Jin Wanliang and rice one stone. Using this kind of hint means that the ultimate treasure is neither gold nor rice, but something else. Excuse me. , During the Warring States Period, what might the Takeda family use as a resource for rebirth?"

"Uh..." Everyone was at a loss for words, and even Tadao was obviously a little troubled because there were too many possibilities.

"Then I'll ask another way," Conan shook his head helplessly and continued to ask. "What resources does the Takeda Shingen family have that can be used by future generations and can be properly preserved here? Prompt, start with the advantages of the Takeda family over other princes."

"The advantage of Takeda Shingen's time..." Tadao was finally able to infer after narrowing his search. "A first-class group of retainers headed by the four ministers of Takeda, the top Takeda cavalry regiment in Japan, the rich gold resources, efficient hot spring resources and outstanding horse resources owned by Koshu itself...!!!" , Tadao himself found the answer.

"The retainer will die, and it is impossible for the descendants to be resurrected to assist him after the comeback. The Takeda Cavalry Corps is the same as above." Conan continued his explanation. "We rejected the gold resource before, so it is not. The horse resource itself requires a large amount of land and an astonishing consumption of food and grass, and it is impossible to hide it. Then, there is only one answer left - what is it? Please answer !"

"Takeda's hot spring!" Tadao murmured.

"The treasure is... a hot spring?" Kimura looked incredulous.

"As evidence," Conan pointed to the board where everyone stood before. "That piece of wood rotted, probably because of soaking or something. And there should have been a mechanism under that piece of wood, which is what I said before, the mechanism used to sense 150 kilograms of weight. But that mechanism disappeared. , just some damp, green paste left."

"Is it moss?" Yuan Tai asked.

"Ferrous sulfide, FeS, and ferrous salts are pale green in solution." Ai Haibara already understood what Conan meant. "It can be produced by the hydrogen sulfide in the hydrogen sulfide hot spring corroding steel materials, so there should be some metal organs underneath."

"Hydrogen sulfide..." Tadao also understood what Haibara Ai meant. "Hot springs...you mean the hot springs used to flow here?"

"In other words," Conan nodded. "The hot spring flows out from here, and after accumulating the entire space, it surges up and becomes your hot spring. As for the essence of this metal mechanism... I guess it should be a weighing mechanism. The greater the weight on the board, the more The deeper the metal mechanism is pressed. After pressing to a certain depth, the mechanism will be triggered and the hot spring will flow out of the mechanism. However, the designers of the mechanism do not understand chemistry, so they do not know that under the erosion of hydrogen sulfide , the metal mechanism was corroded. For this reason, the mechanism used for weighing itself was weakened due to the inflow of hydrogen sulfide hot springs from the gap, and finally could not bear the weight of 150 kilograms, and shattered into **** under heavy pressure, which also That's what caused the hot springs to stop flowing."

"But, the Warring States period has been several hundred years, right?" Mitsuhiko asked curiously. "Why didn't it corrode until three years ago?"

"The hydrogen sulfide in the hot spring is not much, and when the outside of the metal organ is corroded, a protective layer will be formed, preventing the inner layer from continuing to corrode. Therefore, the entire corrosion process will take so long to complete. "

"So, the weighing mechanism was completely damaged, and the hot spring's gushing mechanism was also closed?" Tadao's expression was obviously helpless. "So, is there any way to revive this hot spring? Or... there is no way?"

"I don't know to what extent the whole mechanism has been corroded. It is very likely that there is no way to open the nozzle in a normal way..." Conan spread his hands. "But if you can pry open the brick of the spout, maybe you can give it a try."

"Don't discuss that," Qian Yu's expression suddenly became a little distressed. "Have you thought about a question?"

"How do we go back!?"

"Qianyu," Conan asked, glancing at the hole. "Did you have a hard time coming down? Did that hole have a lot of room for you to pass through?"

"It's no more than 5 centimeters. I was scratched when I came down, and now my shoulders still hurt..." Qian Yu pouted and replied. "If we go back from there, the few of us will be fine, but big brother Tadao will be in trouble."

"If Brother Tadao can't get through, then there must be some other mechanism here that can open the door!" Conan immediately concluded. "Otherwise it simply doesn't make sense."

"Unreasonable?" Tadao was a little strange. "Why is it unreasonable?"

"There is a hot spring above our head. There must be flat ground near the hot spring, so the height of the altar just now must be lower than the normal water level of the hot spring." Conan explained. "That is to say, under the normal conditions of the hot spring, if there is no mechanism to lock the stairs we go down and isolate the water from the altar, then the altar will definitely be submerged, and the wooden Koshu Dou will float up. , then it is impossible for us to see Koshu Tou lying quietly on the plate!"

"If the road will be blocked and the hole above it will be impassable, then who opened the hot spring mechanism in the first place?" Conan continued to explain. "If it is said that the dead man came in to open the mechanism, as Chiba said before, the bones of the dead man will contaminate the water source, making the hot spring unusable at all. Therefore, there must be some escape mechanism here to allow the person who opened the hot spring mechanism to escape. go."

"But if we can't find the trigger for such a mechanism, we can't get out, right?" Qian Yu asked with a frown.

"Um... that's right..." Conan then realized that his thoughts also had loopholes~www.wuxiaspot.com~ embarrassed.

"By the way, I have an idea." Qian Yu suddenly thought of something. "Mr. Kimura, Mr. Tanaka, step back and lean against the stone wall unknown."

"Aren't you going to pit us?" Kimura asked.

"Just to be on the safe side," Qian Yu said while aiming the crossbow hole at the tip of the seamless umbrella at the two. "Please step back!"

Kimura and Tanaka had no choice but to retreat to the stone wall behind them - next to the strangely colored brick - eight or nine meters away from everyone, and more than 5 meters away from the two guns.

"Conan, bring those two guns," Chiyu continued. "Everyone should stay away from those two people, but also stay away from me. It's enough to stand more than 5 meters on both sides of me."

"..." Conan glanced at Chiba who was still standing at the place where the rope was lowered before, and then clearly walked towards the gun. "Is the stone wall between the hot spring above and our space very thin?"

"Thin! Very thin!" Qian Yu looked at Conan and nodded with a smile. "It's all on you!"
