"What a magnificent oil supply facility!"

Led by Kanazawa, the group came to a round oil supply tower seven or eight meters high. I saw that the thick tower was densely packed with pipes of different sizes, and a ladder formed by small metal rods spiraled straight to the oil outlet located in the upper part of the oil supply tower.

"Rubber Hose............ Sure enough, no≡ ̄_ ̄≡. Qianhu, who was small, climbed up the tower and said helplessly to the lonely oil faucet.

"After all, it's been a long time, this oil supply facility." The boy held the oil drum with both hands below, and Yuri adjusted the funnel on the oil drum as she adjusted.

"Well! This is indeed the case, after all, things like rubber pipes are always easy to degrade and deteriorate. Especially, you have to adjust well! ”

“OK！” Yuri said with a gesture below that was fine.

"So .................."

As Qianhu slowly turned the valve, the clear gasoline gradually began to flow out of the oil outlet, at first it was just a continuous stream of oil droplets, and it didn't take long for it to turn into an oil belt and follow the funnel in Yuri's hand into the oil drum in the boy's arms.

"Ahh Oiled, oiled! Looking at the endless flow of gasoline falling in the funnel, Yuri said excitedly.

"What a capability!" Looking at the young man and girl who were taking a drop of oil into the oil drum without revealing it, Kanazawa said in admiration.

"Goo Dong ~ Goo Dong ~" The clear and transparent oil is slowly poured into the fuel tank from the fuel inlet of the half-track car.

"It's full!" Qianhu said as he listened to the sound coming from the oil intake.

"Then we'll pick up another bucket and we're ready to go!" As the boy spoke, he walked to the oil supply tower again with Chito and Yuri.

Half-tracks loaded with fuel carried the group back towards the towers, and as the distance dragged into what looked like residential buildings, there were more and more buildings.

"There are so many residential buildings around here." Yuri said, looking at the buildings on the side of the road.

"The vicinity of the communication tower leading to the upper level was once densely populated. But now there is not even one left. I don't know when the number of people living here has been decreasing day by day, until now. Kanazawa's words were filled with loneliness and sadness.

"So was it the people who lived here who built the tower?"

"Probably not!" Kanazawa said, looking at the map.

"I think this layered city was built by humans a long time ago." The boy answered Yuri's question from the sidelines.

"Our ancestors just lived in this city, at least that's what I thought." Kanazawa added.

"I see."

"Ahh Turn left. ”

"Understood!"

Following Kanazawa's instructions, the car slipped into a narrow gap between the two buildings.

"Can't get close to the tower!"

"Hmmm! Although it can be seen all the time. ”

"This area is still quite complicated, and you have to take a long detour!" Kanazawa explained.

"Isn't this map wrong?" Yuri asked.

"That's right, you can see that the refueling facilities are exactly the same as the location on the map!" Kanazawa argued.

"And how did you draw this map?" Qianhu asked curiously.

"Running around on a motorcycle, you have to climb to a high place to check!"

"That's a big project!" The boy exclaimed.

"That said, you've been here before."

"That's right! At that time, the bridge over the ditch was still there. ”

Kanazawa said as he opened the satchel to reveal the thick blueprints inside.

"Look, this layer is basically drawn on the map!"

"Huh~~ It's amazing! Let me see! Yuri was intrigued by Kanazawa's words.

"Yes, you can, but you have to be careful!" As he spoke, he was about to hand over his satchel.

"Be careful! That guy burned other people's books. At this time, Qianhu suddenly said.

The atmosphere suddenly froze, and Kanazawa stopped for a moment when he stretched out his satchel, then retracted like lightning, hugged his hands fiercely, and the person also hid to the side.

"It's not going to burn!" Yuri said embarrassedly with a red face.

However, Kanazawa still maintained this action for a long time, looking at Yuri with a wary expression.

"Do you cherish these maps so much?"

"This is the purpose of my life."

"What is the meaning of being alive?"

"In a world where you can't see people, there's nothing to do, and if I don't have this, I'm going to die!" Kanazawa said seriously, and the sadness in his eyes couldn't be stopped.

"Excellent! Burn it! Yuri immediately picked up her gun and said.

"Stop! Why should it be? Kanazawa's hands tightened.

"I'm wondering if it's really burning, if you're really going to die."

"Are you a demon?" Qianhu complained.

"I feel like sometimes, Yuri's heart is very bad." The boy teased from the side.

However, everyone knows that Yuri is just talking; Even Kanazawa let out a long sigh of relief after seeing her put the rifle back in place.

"You have something very valuable, right?"

"Something precious? What is the floating wave sauce? Yuri asked the boy after a moment's thought.

"I'm sorry! There are some things that are necessary, but they are not very valuable...... If anything, it's probably life! The boy thought about it for a moment and gave an answer.

"Yours?" Kanazawa asked.

"Nope! I don't think I think about my life and death that much! I just hope that the rest of the people in this world, no matter how painful or sad they are, can live bravely! There's hope because you're alive, isn't it? The boy said with a smile.

"Is it even such a world?" Kanazawa asked.

"Even in such a world, isn't there a meaning to live?"

"Fuba-chan is really a gentle person!" Qianhu sighed.

Because my body will not allow me to die! The boy looked at the black particles that only he could see, and they were emitting from the palm of his hand in all directions. This body .................. Is it a blessing or a curse for me?

"The most precious thing about Sen-chan should be a diary or something, right?" Yuri continued.

"It's precious, but it's not going to die."

"Yuri is, she won't let go of her food when she dies!"

"Not so exaggerated, not so ............"

At this time, both the boy and Kanazawa turned their heads to look at Yuri with a strange expression............

"There's really nothing like that!" As if reading the meaning in the teenager's eyes, Yuri once again loudly denied it.

The car continued to drive forward............

"Right!"

"Roger."

Chiho drove the half-track into the tunnel on the right.

"It should be there soon!" Kanazawa said after checking the map by the light from the mouth of the tunnel.

The tunnel was not long, and the car soon came to the exit, and as the setting sun greeted, everyone saw the majestic building not far from the exit------ the pillars leading to the upper floor.

"It's so big!" Yuri exclaimed.

"It's huge!" Chiho was equally amazed.

"I was prepared for it, but it's still spectacular to actually see it!" The boy looked at the giant pillar dyed red by the setting sun and was also amazed.

"By the way, when you climb to the previous floor, will you still draw a map of that floor?" Yuri turned her head and asked Kanazawa, who was silently staring at the communication tower.

"Hmm!" The answer was so short and firm, and Kanazawa's pupils were incomparably bright at this time.

"I feel like Kanazawa is having fun! Alive. ”

"Yes."

"This is the power of hope, and it is also the meaning of survival!" The boy said with a sigh.

The majestic pillar still stands, watching the changes of the times like a giant, witnessing the rise and fall of human civilization, and helping generation after generation to reach the next level. Today, it has finally welcomed a new guest, and it is also the last group of guests, and the meaning of its existence is probably this!
