"Is this the food processing factory Ishii was talking about?" Yuri said, looking at the building in front of her.

"I guess I'm going to have to go a little further inside, right?" The boy replied.

"Well! What exactly does Ishii mean? When you arrive, you will know where the road is. ”

"Sa~~ Let's go in first!" Yuri urged.

"Got it!" As he spoke, Chiho drove his car into the building.

After entering the building, the three of them realized that in front of them was a very large pipe............

"Na! Could it be that! You'll know where the road is when you get there............" Yuri said, pointing to the giant pipe in front of her that she could walk up to.

“…… Well, I always feel that something is not right, but this is the only place. Qianhu said.

"Na! What does Funa-chan think? ”

"Well! I think it's better to take a closer look, after all, although the pipe in front of me is very large and obvious, but I took a closer look and found that there are actually many smaller pipes connected to the back of the giant pipe. The boy said.

"Ahh Really, isn't it a road above the pipe? Qianhu said.

"Huh? Why? Yuri asked, confused.

"You~~ Didn't Ishii say it? If you go to it, you can understand, that is to say, the road should be very direct and clear, it cannot be like a maze, if you walk on the pipeline, then there will be countless branches and forks, so it is not directly clear at all. Chiho explained.

“………… I still don't understand......" Yuri said, scratching her cheek in embarrassment.

"Well! In fact, the pipes are too complicated to fit Ishii's description of the road leading to the food processing plant. The boy said.

"Oh! I see............" Yuri suddenly realized.

"But there's nowhere else to do it but this pipe?" Qianhu said suspiciously.

"Are you still going to walk on the pipe?" Yuri looked at the pipe and jumped on it.

"Yu! Come down, it's not all said no! Chiho called out to Yuri on the pipe.

"Chi-chan will come up too! It's spacious! You can all run! Yuri said as she ran back and forth on the giant pipe.

"No, no, no! I'll forget it! Qianhu refused in a cold sweat.

"Good food!"

"You're so long-winded!"

"Well! After all, Chima-chan is not good at high places! Why can't you always overcome it, high places. Yuri said confusedly.

".................." Qianhu was speechless.

"Yuri, Senho! Found your way! The boy's voice came from under the pipe.

"Fubo-chan? Where are you? Yuri asked.

"I'm down there, you guys go to the railing next to the pipe and look down!"

"Oh! There's even a ladder here. ”

Yuri jumped off the pipe and ran to the railing to find that there was a ladder leading to a platform below where there was no railing, and the boy was standing on the platform.

"Come down! The road is just below. The boy beckoned to Yuri and Chiho.

"Uh~~It's so high............" Qianhe looked at the platform below and found that there was a distance of about ten meters between the ground and the platform, which was already very high for her.

"Chi-chan, let's go down!" Yuri said to Chito regardless of it.

"Wait a minute, Yu! I haven't prepared for it yet............" Before Chito could finish speaking, Yuri picked him up and climbed down the stairs.

"There's a door next to the giant pipe!" Yuri said as she descended to the platform and looked at the portal where the platform and the pipeline met.

"Doesn't it matter if you have a thousand households?" The boy stepped forward to help up Chino, who had lost his strength after climbing down the stairs because of his fear of heights.

"It's fine!" Chiho stood up with the boy's wrist and said.

"Qian-chan, good dish!" Yuri teased.

"Long-winded!"

"That's great! No need to walk on the pipes. The boy said with a smile.

"That's right!" Qianhu agreed.

"Then let's go inside!" Qianhu was the first to walk in.

"Let's go in too!" The boy said to Chino, who was already able to stand on his own.

"Hmm!"

The two followed the footsteps of Qianhu into the giant pipeline in front of them.

"Ahh There's lights inside! Yuri said after seeing the boy and Chito walk into the pipe.

"Ahh Really. And there are arrows to mark the direction. Qianhu also said in surprise.

"I see, Ishii said that he would know that it was in the pipeline!" Yuri said with a hammer in her left hand and in her right hand.

"That's true! With these arrows, you can really get to your destination without a map! The boy said.

"Great, we don't have to go up there, we're going to get lost!" Qianhu said.

"After all, Chi-chan is afraid of high places!" Yuri said.

“…………”

"It's really hard to treat, I'm afraid of heights. …… Why? Yuri asked, looking back as she walked ahead.

"What, why?"

"Because we haven't been living on high ground?" Yuri continued.

"It feels a little different!" Chiho replied.

"What's different?"

“………… Yes! Is Yu hungry now? Qianhu suddenly asked.

"Hmmm! Hungry. ”

"But you're always hungry, aren't you?" Chido continued.

"No, I'm usually hungry, but now I'm even hungrier, very, very hungry!" Yuri replied as she walked forward......

"Ahh I see, that means Chi-chan is very, very scared now? ”

"Well! Pretty much. Qianhu thought about it and said.

The three of them kept walking forward, constantly changing from large pipes to small pipes, and then to large pipes, and finally appeared in front of them an oversized pipe, but to enter the pipe, they had to climb a ladder tens of meters long............

"Hmm............ It's so high, it's too high! No, no, no! I can't go down like this! Qianhu just glanced down and immediately retracted, and the two trembled.

"Mo~~~ Chi-chan, we can only get to the food processing factory through this place!" Yuri persuaded.

"But............ Yes! That's right, that's how it should be! She said as if she remembered something.

"So?" Yuri's face was full of questions.

I saw Chiho take out a rope from his backpack and tie himself and Yuri together.

"Chi-chan, I really like it, like this." Yuri said, looking at the rope.

"I don't like that!"

"If you fall...... I'll be implicated. Yuri broke down in a cold sweat.

"No, as long as I fall down, I can get my hands stuck in the ladder the moment!"

"It's a little too difficult!"

"What the hell is this rope that ends together?" The boy complained.

The boy who originally climbed down saw that the two girls had not moved for a long time and climbed up again, and then he heard the strange solution of Qianhu about going down the ladder.

"I can't help it! Because Chi-chan is very afraid of high places! Yuri said to the boy.

“………… Although I knew that Qianhu was a little afraid of heights, I didn't expect it to be so serious! No way! Yuri, you can find a longer rope to tie me and Chiho together, so that if Chiho falls, I can still share the burden. The boy said helplessly.

"I see! It can still be like this! Yuri followed the boy's words and tied the long rope she found around the boy's waist.

Under the guarantee of double insurance, Qianhu finally began to climb down tremblingly.

"Chi-chan! Don't look down! Yuri reminded.

"Hmm!"

After being busy for a while, Qianhu finally went down to the bottom of the pipe, and the moment he touched the bottom, he collapsed on the ground and slowly slid down the slope.

"I really don't want to go any further." Chito muttered.

"But since there's food ahead, we'll have to keep going!" Yuri said after stepping down the ladder behind Chino.

"Hah~~~~" Qianhu let out a moan powerlessly.

"Roar~~ Hurry up!" Yuri said as she picked up Chiho from behind.

"If only I could live without eating or drinking!" Qianhu said.

"That's not life!"

"That's it! I think as long as we walk a little longer, we should be there, hold on! The boy reassured.

"Since Fubo said so, then hold on a little longer!" Chiho said after standing up.

"Hey!"

"Uh-huh............"

"Hey!"

"Uh-huh............"

"Chi-chan!"

"Uh-huh............"

"One, two!"

"Uh-huh......"

“ONE、TWO！”

"Uh-huh............"

Chinohe slowly moved forward under Yuri's push.

"There's such a big pipe!" Qianhu sighed.

"I can't see it from the outside!"

Two young girls walked behind the boy.

"There's some weird garbage falling here, it's huge!" Yuri said as she looked at the giant gear passing by.

"I guess I was rushed over! If you usually have this kind of arrow, it will be much easier! Qianhu said as he looked at the road sign on the side wall of the pipe.

"Huh!! That's boring, isn't it? ”

"It's boring or something............

"Ahh It's still not interesting to walk this way, why don't we go that way? Yuri said whimsically, pointing to a black hole at the intersection of pipes.

"Rejected! The destination is just ahead, who would ignore the signs............"

"There's one here!" Yuri raised her hand and said.

"Honestly, don't do it?"

"I'm sorry!"

"Ha~~~ If you walk like you, you will definitely get lost, and if you become like that, you will be even hungrier than now! And then die............" Chiho said with a sigh.

"That's it! Let's keep going! Yuri compromised to ............

"It's here!" The boy's voice came from the front, which shook the spirits of the girls behind him.

"Sen-chan ............"

"Yes! Let's go. ”

The girls cheered up and walked towards the entrance of the passage in front of them, and in front of them was a flat land, which looked like the roof of some kind of building, and a ladder protruded its head from the hole in the roof............

"Looks like we'll be there just by climbing down this ladder one more time!" The boy said.

"Hmmm! It's the same as Ishii described! Qianhu looked at the map again and said.

"Is it finally here? Food Processing Plant! Yuri exclaimed excitedly.
