Conan: The Mechanic

"Doctor, are you sure it's okay?" Conan asked while sitting in the passenger seat, looking at the road conditions outside worriedly.

"Uh..." Dr. A Li was also a little under-confident, because the current situation was really not right - the Beetle was not driving on a high-quality asphalt road, but on a hilly road full of potholes and stones.

"Anyway," Qian Yu was also lying on the window, looking out, worried. "We're definitely not on the right path now."

"What's more, we've been driving for too long," Haibara glanced sadly at Chiba's watch beside him. "It's been open for over an hour."

"There are even worse things," Conan sighed, glancing at the dashboard. "It's over!"

"Ah?" As soon as Qianyu made a questioning sound, she immediately made a "bang" sound - it was not Qianyu's mouth that made the sound, but Qianyu's head, which was in close contact with the back of the passenger seat.

The car started to slow down and then stopped in place.

"The engine is broken?" Touching her aching head, Qianyu looked at the engine cover at the front end of the Beetle. "No smoke... What's going on?"

"Hey hey hey hey?" Dr. Li tried to turn the key in shock, but the car could not be restarted.

"It's not a mechanical failure, it's running out of oil!" Conan said speechlessly. "Doctor, are you not cheering?"

"Ah..." Post-Doctor A Li wailed in hindsight. "Oh my God!!! I forgot!!!"

"What should I do?" Qianyu also glanced at her watch - it was 3:06. "I think I have reason to suspect that we have plunged forty or fifty kilometers into the deep mountains and old forests, and it may take eight or nine hours to go out."

"Doctor," Conan asked. "Quickly use your mobile phone to call the emergency repair department and ask for help!"

"Oh yes!" Dr. Li took out his phone in relief, but after taking a look at it, he wilted again. "No signal..."

"Uh..." Qianyu sighed helplessly and leaned back on the seat. "What do we do now?"

"Do we still have water and food?" Haibara asked sadly.

"Wait a minute," Conan suddenly thought of something. "Maybe we can get the Beetle to drive about another ten kilometers if we make good use of the water left in the tank?"

"Water?" Qian Yu was stunned for a moment, and then she realized what Conan meant. "Are you going to take out the water in the tank and use the oil at the bottom of the tank?"

"Qianyu-kun, what do you mean by this sentence?" Ayumi thought what Qianyu said was almost a riddle, so Ayumi asked.

"Do you know how the car works?" Qianyu thought for a while, organized the language, and replied. "The gasoline in the fuel tank of the car is pumped out by the fuel pump through the fuel pipe on the side wall of the fuel tank to drive the four-stroke engine. Because the fuel pipe is connected to the side wall of the fuel tank, at the bottom of the fuel tank, a part of the oil will remain at the bottom of the fuel tank, It can't be pumped out by the oil pump, so naturally it can't be used. Water is heavier than gasoline, so if you pour some water into the tank, you can lift the gasoline at the bottom of the tank, and the gasoline can be pumped in by the oil pump. There is still a long way to go.”

"However, I'm afraid we won't be able to do that now." After Chiba finished explaining, Haibara Ai looked at the terrain before and after and complained. "There are slopes in the front and rear. If the water does pour, the water is likely to be drawn into the engine due to the tilt of the fuel tank when the car is climbing."

"Yeah..." Conan tapped his forehead in pain. "But I really can't think of a good way... I'm afraid I can only give up the car first and walk forward."

"What about that night?" Qian Yu glanced at the dirt road in the woods that she didn't know how far ahead, and pouted. "Go all out or come back?"

"Everyone can't take the risk..." Conan was obviously also having a headache. "But if we go back here for the night, our food reserves will be insufficient, and we will not be able to replenish our physical strength. If we stay here for the night, our ability to go hungry tomorrow will definitely be much worse than today."

"Let's take a look first," Qianyu shrugged. "The question of whether to continue or turn back will be discussed on the road. Maybe there is a village not far ahead."

. . .

After walking for an unknown amount of time, the sound of water flow suddenly appeared in front of me. I didn't know when, a small stream flowing through the mountain road appeared not far in front of everyone.

"This..." Before arriving at the stream, Qianyu looked at the direction and speed of the stream, and was slightly surprised.

"There is actually a small stream here?" Yuan Tai ran behind Qian Yu and looked at the scene in front of him curiously.

"I think this creek has something to do with the lake we saw before. I'm afraid this is the upstream water source of that lake." Qianyu shrugged.

"No way?" Ayumi, who arrived later, glanced at the width of the creek. "Such a small river upstream of such a large lake?"

"Did you see it from the leaves?" Conan's voice sounded from behind several people.

"Leaves?" Both Ayumi and Yuanta were stunned. "Where are the leaves?"

"In the water," Qianyu motioned for everyone to look at the creek - every now and then one or two strangely shaped leaves flow down the river~www.readwn.com~ This kind of leaf does not match the tree species on both sides, it should be floating upstream , and the lake has the same leaves floating in it, so they should have the same source of water, most likely this stream is upstream of the lake. "

"Doctor," Qian Yu said, looking at the water source. "Have you got a bottle with you? We'll need some water, just in case!"

no respond.

"Doctor?" Qian Yu looked back suspiciously and saw Dr. A Li sitting on the side of the road with her head lowered. "Doctor, what's wrong with you?"

After Conan saw Dr. A Li's abnormality, he immediately ran to his side. "Doctor, what's wrong???"

"It hurts..." Dr. Li stroked an ankle and gritted his teeth.

"Is the ankle sprained? Or is it a fracture?" Qianyu looked at Dr. Aga's injured ankle with a worried expression. "Can you move? Give it a try, and stop moving if it hurts."

"I can barely move...but it hurts..." Large drops of sweat kept dripping down Dr. A Li's forehead.

"Has the pain eased or maintained its original intensity?" Haibara asked sadly.

"It still hurts a lot, but it's a little lighter..." Dr. Agasa replied.

"I'm bruised, I'm afraid I won't be able to move freely for the time being, but I'll be able to recover soon. However, the doctor urgently needs a rest now." Haibara mournfully concluded.

"Not good..." Qian Yu frowned. "We certainly can't abandon the Doctor now, but that also means we're afraid we can't move on..."

"Hey..." Yuan Tai's demented voice made everyone look at him curiously, only to see him pointing to where everyone came from and saying. "That is..."

"A car?"

In the direction where the few people came, an off-road vehicle came galloping.
