"Who is this?"

“…… Thousand households ......"

"What about him?"

“…… Floating ......"

"What about me?"

“…… Yuri ......"

"That's amazing! Nuko is all right! Yuri said excitedly.

"The language is gradually enriched!" Qianhu said with a sigh.

"Because I gave it to her." Yuri said proudly.

"It's really amazing! Whether it's Yuri or Nuko............" the boy also praised.

"Hey~~ Next...... So what's this called? Yuri asked, pulling out a bullet.

“…… The bullets that have been eating......" replied Nuko without hesitation.

"It's a bullet, but it's more accurate to say it's a 6.5 caliber bullet......" Yuri explains.

“…… 6.5......" Nuko watched as Yuri pulled something else out of the car as she repeated the caliber of the bullet.

“nuyi？”

"This one is 12.7 caliber, this one is 20!" Yuri spread out her palm to Nuko, explaining the type of bullet in her hand.

"Don't pick up such a big bullet and come back......" Qianhu said speechlessly.

"Well! Anyway, it can be used as food for nuko, isn't it? The boy said with a smile.

"I'm afraid it's not going to work with such a big one......" Qianhu said in a cold sweat.

"I want to eat 20 ............," Nuko said at a glance as she took a fancy to the bullet with the largest caliber, drooling.

"Oh~~ It's a challenger! Will it work? Yuri said in surprise.

"Hey, hey......" Qianhu drove his car speechlessly and continued to move forward.

“………… It's a little uncomfortable......" Nuko said, holding the bullet and trying to shove it into her mouth.

"Come on!" Yuri cheered.

"Don't be too pushy............ Not? Chinohe seemed to have noticed something, and the car made a sharp turn into another passage.

"Do you like chariots?" Yuri asked, noticing the cart parked in front of her.

"It's not a chariot............ "Chido said as he parked the cart in front of a pile of clutter. She got out of the car and trotted to a stop in front of a square object............

"I'm not mistaken............ It's a book! Qianhu carefully picked up the lonely books that fell on the ground, patted the dust, and said excitedly.

"What kind of book is this?" Yuri asked casually.

“………… I don't understand the words............ What about the writing of a long time ago...... Unlike our culture...... Can grandpa understand this? Qianhu said.

"Fukiba-chan should be able to read it............" Yuri asked the boy curiously.

"Sorry! I'm not very good at English............" the boy said, scratching his head embarrassedly.

"English? Is it the text above? Qianhu asked curiously.

"Hmmm! It is written in a place far away from the city, and it is said that it was used as a universal language in the past. The teenager said Kopp.

“…… It's amazing......" Qianhu said excitedly.

"Because I'm not very good at it, I can only understand a little bit...... "The boy took the book in Qianhu's hand and flipped through it.

"Can you tell me, what's on the cover?" Qianhu asked excitedly.

"Well! …… War and Human Civilization...... That's what it means! The boy looked at the cover and said.

"That's the name of the book!" Yuri said.

“………… What about the rest? Qianhu asked further.

"Sorry............ There are a lot of unfamiliar words in it, so I can't interpret them correctly............" The boy said embarrassedly.

“………… Is it...... Forget it, take it first! Although Chido was a little disappointed, he still put the book in his backpack.

"Huh~~~? But you can't read it! Yuri asked curiously, holding the cannonball in her hand.

"But this is a very rare thing after all............ "Chido turned his head a little embarrassed and whispered.

"Chi-chan told me not to pick up extra things?" Yuri laughed.

"Hmm............" Qianhu was speechless for a while.

"Aren't you picking up this kind of thing yourself.................." Yuri said with a strange smile, poking Chido with the tip of a cannonball.

"It's because you don't understand the value of books ............"

"What you can't eat has no value............ "......Nuko said as she struggled to shove a 20-caliber bullet into her mouth.

"I feel like Nuko is talking more and more like Yuri............" Chiho said helplessly.

"Moga............" Nuko continued to fight against the large bullets.

“………… So what is it that You is holding in his hand now? Qianhu asked.

"Cannonballs." Yuri said as she should have been.

"You'll know if you see it............ That's not what I'm asking! Qianhu said with a little tiredness.

"I want to feed Nuko......" Yuri explained.

"No, no, no! This definitely won't work, right............ Throw it away! Qianhu said immediately.

"Mo Ga Mo Ga ............ (Swallow) "With Nuko's efforts, the bullet that was quite huge for her finally came down.

"Ahh The 20 caliber swallowed......" Yuri cried.

"Isn't it!" Chiho was a little surprised.

"That's amazing! It's a lot heavier! Yuri grabbed Nuko's foreleg and lifted her up.

"nuyi~~~~" Nuko's body stretched out by the weight of the bullet in her stomach.

"Don't bully her too much............" Chito said.

"Chi-chan! Get your camera! Yuri urged excitedly.

"Nuko's body is still very elastic............ the boy said curiously, looking at Nuko who was stretching as Yuri swung.

After taking pictures, the trio began to move on, and the staircase, which had been only accessible to people due to the amazing nature of the half-track, became a passable road.

"Is it because of the difference in culture that you can eat bullets?" Yuri asked, holding Nuko in her hand.

"Well............ It's more about ecology than culture...... "Senhu said as he drove up the long staircase in front of him.

"That's right............" Yuri said, squeezing Nuko's soft forelegs.

"Culture refers to the distinction between human groups such as language and writing, and there have even been conflicts because of this in the past!" Chido continued.

"Hmm............" Yuri chimed in.

"In addition to culture, people have even clashed over the taste of one food in the past!" The boy interjected with his fingers up.

"Huh!? Is that so? Tell me carefully, Fukiba-chan! Completely different from the indifferent attitude just now, Yuri's face at this time was full of curiosity.

“………… You've always been very keen on food............" Chinohe said speechlessly.

"Well! Regarding the conflict of food tastes, the most prominent of them should be the debate about whether tofu brain is salty or sweet. The boy thought for a moment and said.

"Tofu...... Brain? Is it the brain of an animal called tofu? Qianhu asked.

"It tastes good......" Yuri said, drooling.

"Tofu brain is not an animal's brain, it's actually the juice of soybeans soaked in water and ............ground into a plaster cast to solidify," the boy explained.

"I see............" Chiho said, nodding.

"I really want to eat it! This thing is called tofu brain............" Yuri said with a full appetite after hearing this.

"I'm sorry! Now I don't have any materials on hand to make ............," the boy said helplessly.

"Ugh! Hmm............" Yuri's expectant expression immediately turned to disappointment.

"Continuing from the previous topic, did people in the past actually clash because of different food taste preferences?" Qianhu was a little unimaginable.

"Chi-chan, I think it's because food is also a part of culture!" Yuri thought for a moment and said.

"Well! Surely it should be! Qianhu said in agreement after thinking for a while.

"Different regions and cultures generate different needs, and different needs create hidden dangers for conflicts between each other, and the outbreak of these hidden dangers becomes war." The boy continued.

"Is this why there are so few people in this city?" Qianhu asked.

"Although it is largely due to the fact that there are fewer and fewer materials needed to survive, who can be sure that it has nothing to do with this!" The boy said.

"I see, cultural differences lead to conflicts, and these conflicts lay the groundwork for the outbreak of war............ Obviously, you can avoid it if you communicate well, right? Why should we use war to solve it! Qianhu said with a little sadness.

"Well! Who can explain these things............" the young man said helplessly.

"Na...... I wonder if war is also a part of culture? Yuri said suddenly.

"Yes! It's called the .................. of destruction of culture," Senhe said after thinking about it.
