The huge library was more than just a wrench to the trio............ Whether it's Chino, who simply likes books, or Yuri, who is passionate about food, they all find their favorite books in this huge library............

"Luckily, there's room to carry around! Otherwise, I would have just sighed at these books! Senhe said as he sorted the books selected from each bookshelf into his personal space.

"Speaking of which...... Why did Akiba-chan put the jet port of that rocket into space? ………… It feels like it's useless than these books! Yuri said as she put a few books about fish and food into her space.

"Because these will be used!" The boy smiled and helped Chito put the books that couldn't fit into Yuri's space.

“………… Usage? ”

"Hmmm! Will definitely use it...... You'll understand when the time comes! The boy said mysteriously.

It took two full days to select the books, and if it weren't for Yuri and the boy's strong dissuasion, it is estimated that Qianhu would want to stay for a few more days and pick them slowly!

"Ah............ Ahh There are so many books, aren't they? In the face of the dissuasion of the boy and Yuli, Qianhu could only give up and continue to pick books with great pity.

Although it only took two days to pick out the books, it took three days and two nights for the three of them to sort out and classify them.

"Luckily, the food is quite sufficient!" Yuri looked at the excited Qianhu and said helplessly.

"Well! It's rare for thousands of households to be so happy............ It's okay for us to spend a little more time. The boy reassured.

"Na! Chi-chan! ”

"Huh? …… What's up? Especially. ”

"Are you ready to go?" Yuri reminded her companion who still had the lingering excitement on her face.

"Oh! ………… OK! OK! …… I'm going to start the car......" Chido finished and ran to the side of the half-track and pressed the start button of the car.

Puff puff puff............ Some of the hoarse engines started to work, and the car also ran in front of the boy and Yuri under the operation of Chino.

"Come on! Let's continue to ............ upwards," Senhe said after parking the car.

"Hmmm! Get on board right away! Yuri said, closing the somewhat full carry-on space.

"That's it!" She said with a small jump and climbed onto the body.

And the boy also made a move to Chito after taking the nuko who climbed into the car into his arms.

"So...... Let's go! As she spoke, Chido released the brakes, unscrewed the accelerator, and drove the car that had been with her for a long time out of the library that made her a little nostalgic............

After leaving the library, the road was a continuous upward slope, and the three of them were guided by the map to climb the slope and enter a strange room with many large robots and energy pipes............

The room was so large that the three of them could only reach the exit on the other side via the viaduct at the entrance............ During this period, the boy always listened to the movement of the engine from time to time............

The viaduct didn't take long for the three of them, and after more than ten minutes of driving, the familiar sunlight illuminated the faces of the three again............

The long-lost sunshine made Chiho and Yuri very excited, so they didn't notice the sad screams of the old guy's heart under them............ I don't know that this half-track car, which carried them I don't know how many miles they have walked, has reached the time when the gas runs out and the lamp runs out!

As if it was a small opportunity, a small steel bar stuck into the wheel through the gap in the tracks of the car, and continued to rotate between the wheels as the car advanced............ Then, with the clattering sound of metal, the halftrack lay on its stomach............

The crumbling track blades clanged and fell to the ground, and the car came to a complete stop after the last roar of the engine............

Bursts of ominous smoke came out of the engine's heat vents, rendering the somewhat dead silence............

"Is the track broken?" Yuri asked, jumping out of the car.

"Hmm............ If only that were the case! Qianhu looked at the smoking engine exhaust vent and said uneasily.

“………………？”

Yuri, who knew nothing about mechanics, didn't know what the ominous smoke meant, she just knew that a car with broken tracks couldn't continue upward.

"Qianhu, let's try to see if the engine can start!" The teenager suggested.

"Hmm! Yes! The black-haired girl nodded.

With some hesitation, she pressed towards the familiar position of the start button............

"I have a bad feeling............ "Chino, as usual, twisted the key and pressed the start button............

The car didn't respond............ Like an old man who has died, he can no longer wake up............

Qianhu repeated it several times without believing in evil, but there was no other sound except for the slight sound of electricity emitted by the battery............

"Sure enough............ Won't the engine hit either? Qianhu said completely abandoned.

"Huh? Can it be fixed............? Yuri asked worriedly.

"I don't know! Check the engine first............ Can Fubo help remove the shell? ”

“………… No problem! The boy took the wrench handed over by Qianhu and said.

"Sen-chan...... Is there anything I can do to help? Yuri asked.

"No," Qianhu said decisively.

"Uh.................."

"Just kidding............" As if sensing that his tone was a little hurtful, Chido added.

"Seriously! As long as I can help, just ask! Yuri said again in earnest.

“………… Then please take off the lid with Ukiba! Chiho commanded.

"Oh!"

Yuri obediently took off the lid from the car with the boy and put it aside, and then she could only stand on the side with the boy and watch............

After all, the next thing is not something that she and the boy can interfere in......

"Can you only wait?" Yuri said as she climbed up the pipe to the side and hummed.

Chito skillfully unscrewed the nut on the surface of the engine, and her face became worse and worse as the inside continued to show............

"Thousand households............ Don't be in a hurry! Take it easy! The boy reassured.

"It feels terrible............ It looks like you can't find any problems outside............ It seems that the problem lies in the core............" Qianhu said with some fear as he raised his head.

Then she saw Yuri sitting on the pipe doing nothing and humming a song............

"Stop singing there!" Chiho angrily threw the wrench on Yuri's helmet and shouted.

Yuri, who was hit on the head by a wrench, did not cry out in pain, but said with some reluctance:

"Sorry! ………… Because I can't do anything............ At least singing can make you happy............"

“………… I'm sorry............" Chido said with some regret.

After this episode, Qianhu went on to investigate a few less important parts............ However, no major problems were found............

Time is always passing by in a wholehearted work, and before you know it, the sky is already dark............

The boy went to prepare dinner for the three, so there were only Yuri and Senhu near the broken down half-track............

"It's starting to get dark!" Just as Qianhu was thinking like this, her vision suddenly brightened! When I looked back, I realized that it was Yuri's work............

"I saw a lamp and brought it!" Yuri said as she adjusted the position of the lights.

"Thank you!" Qianhu said movingly.

"Hmm~~" All she answered was Yuri shaking her head slightly.

While Yuri fixed the lampstand, the boy also walked over with a steaming pot of corn paste............

"Let's check after eating!" He said softly to the two girls.

"Hmm............ Wait until I get the engine off the car and eat it! After saying this, with the help of Yuri, Chido unscrewed the bolts holding the engine in place and moved the engine to the snow.

After all this, she took the food handed by the boy and sat down on the edge of the car with Yuri to eat............

Probably too worried about the condition of the engine, Chido ate faster than Yuri for the first time, and she quickly solved the food and pounced on the engine again to check it............

The night passed, and the morning sun shone on the half-track, as well as on Chito's oil-stained face............

"Na! ………… Do you want to take a shower? She asked with a blank face that had nothing to do with her previous work.

"Huh? ………… I want to ......," Yuri replied honestly.

"If you look at it this way, it's almost like a bathtub!" Qianhu said as he looked at the empty body.

“………… I want to transform this into a bathtub......" Chinohe said.

"Huh?! Is the engine gone? Yuri said in surprise.

“………… There was a crack in the cylinder, and the propeller shaft couldn't rotate...... Even if you fix this side, it will break there...... This car looks like it's reaching the end of its life! Qianhu explained in a heavy tone.

Looking at the thousand households as if they had smoked something, Yuri had mixed feelings in her heart............

“………… I see! What should I do? She bit her lip and said.

"Collect the snow first......"

"Oh!" Yuri nodded, and together with Chino, they used a shovel to pile all the snow on the ground in the body.

After piling up the snow, Chido removed the fuel tank under the car, and used the gasoline inside to wet some unused rags as fuel and put them under the car to ignite......

"Then it's just a matter of waiting for the snow to heat up............," Senhu said after blocking the hole with adhesive and a wrench.

"What are you doing?" The boy seemed to have just finished some manual labor, and he ran over and asked, sweating profusely.

“………… The engine and propeller shaft are broken! So I can only turn it into a bathtub............" Senhe said in a trembling voice.

“……………… Please mourn! The boy could only pat her on the shoulder and comfort her.

"Let's take a bath together later! ………… It's just big enough for three people to take a bath at the same time............," Chiho said, turning his head to the boy.

“………… Can it really be? The boy asked a little strangely.

"It's okay! ………… After all, Fubo also wants to take a bath! ………… Let's have a piece! Qianhu said indifferently.

“…… Now, the words of Fuba-chan............ It's okay! Let's take a bath............ I feel like I only have this one chance before I get to the top! Yuri said the same to the boy.

“………… All right! ”

The three of them stood together, quietly watching the snow completely melt into snow, and then gradually heat up from the raging flames under the car............
