After several days of refinement and reinforcement, the aircraft was finally completed. Accompanied by the familiar sudden sound, Qianhu pulled the plane with his beloved half-track and slowly entered the take-off room.

"Good!" Yuri watched the plane come to the designated position and immediately stopped.

"Finally ready............ Ishii said, looking at the improved aircraft.

The improved aircraft not only had a certain reinforcement of the strength of the wing, but also connected under both wings with strong steel cables with spare fuel tanks under the fuselage to prevent the wing from breaking from the root. Although it has increased a lot of weight, the safety has been greatly improved.

"Well! So be it! The boy looked at the energy on the bracelet that had dropped from 64% to 34% and smiled.

"I'm finally ready............" Ishii looked at the plane parked on the runway, mixed feelings.

"So...... To celebrate the completion of the plane, cheers! Ishii took the lead and raised his glass.

"Cheers!" The boy followed.

"Cheers!" Chinohe and Yuri raised their glasses as they did as teenagers.

The four cups collided together, spilling the liquid on the table.

"Na...... What does it mean to toast! Yuri asked Chino.

"It feels like something to do when you're celebrating something!" Qianhu thought for a while and said.

"So the taro is also two pieces per person." Ishii took out the boiled taro from the cauldron on the table and handed it to the three of them.

"Two taro!" Yuri exclaimed excitedly.

"I'm sorry! As the last meal of goodbye, it should have been a little more hearty. The boy said apologetically.

"It's a pity that I didn't get to eat the Ukiami dish at the end, but that's okay, after all, I miss the taste of boiled taro!" Ishii said with a smile.

"Delicious! Boiled taro is also very good! Yuri on the side said as she munched on her taro.

"But is it okay? Give us two pieces ............," Senhu said, taking a bite.

"It's okay! It's impossible to cram all into the plane anyway. ”

"Ahh In that case, I want a little more. Yuri said immediately.

“…… Yuri has a thick skin............"

"Sorry! Sorry to bother you. Qianhu said embarrassedly.

"It's okay, because of the reinforcement of the fuselage, there are still some taro leftovers, you can take those away." Ishii said as he took a sip of water.

"Huh? Can it really be? ”

"It's okay! This is a parting gift! Also, I think there's a little bit left in the food production facility, so I'll draw you a map later! Ishii thought for a moment and said.

"Really? Thank you very much! Qianhu said excitedly.

"Looks like the next destination has been decided!" Yuri said as she munched on the taro.

"Yes!" Thousand households returned.

"It's a strange question now, but can I ask where you're flying?" The boy asked.

"That's right! We only seem to know that you want to leave the city. Qianhu on the side also asked.

"Of course I'm not going to fly around without a purpose!" Ishii said, took out a map, spread it out on the table, and said.

"What is this............" Chiho asked.

"This is a route map found at the base, and it seems that a long time ago I relied on airplanes to travel to and from nearby cities............" Ishii said, pointing to the map.

"Other urban !!" The boys and girls shouted excitedly.

"That's right! I used the observation machine, and finally on a clear day, I barely confirmed that something was on the other side. ”

"Didn't you expect it to be on the other side?" The boy muttered.

"Yes! I reconfirmed it yesterday, and it seems that it still exists. ”

"Is there a city nearby............ What kind of place will it be............" Yuri said with some longing.

“…… Hawkers! You should know when you go! Ishii said.

"Can you know the straight-line distance?" The boy asked suddenly.

"Well! Although the record of this on the map is blurred, according to the record on the observation machine, it should not be more than 300 kilometers. Ishii thought about it.

"That should be enough!" As he spoke, the boy took out a backpack from under the table and placed it on the table.

"What is this?" Ishii asked.

"Flying pack!" The boy explained to the equally curious girls.

"Flying packs?" Ishii and the girl looked suspicious.

"Although it can't fly as far as 2,000 kilometers like an airplane, this thing can fly for about 6 hours on a full charge, and the distance can only fly about 350 kilometers due to material limitations." The teenager explained.

"Three hundred and fifty!?" Yuri called.

"In other words, can you fly to the city on the other side of the river with this alone?" Qianhu asked.

"That's right! It's just that because it's a solo jetpack, and the material gap, compared to the original, it can't carry anything other than the flying crew and a small amount of survival materials. The boy continued.

"So how much can you carry?" Ishii asked.

"Considering that Ishii weighs no more than 10 kilograms as a woman, there is no problem." The boy replied.

"Floating waves...... When did you make this thing? Qianhu asked in surprise.

"I think it was after you fell asleep!" It was Ishii who answered.

"No wonder Fubo-chan has always looked listless lately." Yuri suddenly realized.

"It's alright! I wouldn't have been able to do it without this............" said the boy, revealing his bracelet.

"Ahh Find that on the battlefield! Yuri said in surprise.

"I thought it would only work as a watch." Chiho was also a little surprised.

"A few days ago, this bracelet regained some functions by absorbing solar energy, and I found the production drawings of this from those functions, and it happened that this base had charging equipment and materials needed for production, so I used my rest time at night to make this."

“………… In the past, human technology was really amazing! Ishii said in surprise as he looked at the jetpack.

"Yes!" Chiho responded.

"That's amazing!" Yuri is also unaware.

"I think so, after all, this plane does not have the opportunity to test flight, even if we help it to do a certain amount of reinforcement in the later stage, it is inevitable that there will be problems, maybe on the way, maybe when it is about to arrive, the worst case may be that there will be problems soon after departure. To be on the safe side............"

"You made this for me?" Ishii said with some emotion.

"Like you just said, it's my parting gift!" The boy scratched his head embarrassedly.

“………… Thank you so much! Ishii bowed excitedly.

"Great! Ishii. Yuri said.

"That's right!" Chiho also chimed in.

"Without further ado, I'll teach you how to use it first!" The boy handed the back bar to Ishii.

"But is it too late?" Qianhu asked worriedly.

"Because this thing is still quite convenient, the main thing is to familiarize Ishii with the operation in order to deal with emergencies." The teenager explained.

So the next hour ended with the boy teaching Ishii............

"Hey! cheese。 "Four people stood in front of the plane and took a picture.

"So...... See you soon! Ishii began to climb up the ladder towards the cab.

"Ishii,...... You're determined to go, right? Chinohe asked Ishii, who was already sitting in the cab.

"Of course! That's why I've been making it all the way to this moment. Anyway, it's great to meet you! Ishii said as he looked at the three people below.

"I've heard you say this many times!" Yuri said confusedly.

"It's not just about work! Be able to make it visible...... That's the most important thing! ”

"It's an honor for us to be able to witness this." The boy said.

"If anyone witnesses it, it will be history!"

"Na!" Chiho shouted to Ishii, who was operating the instrument, "Will Ishii be the last pilot of mankind?" ”

"Maybe......" Ishii looked down and thought for a moment.

"That's it! Let's go! She closed the cockpit door.

"This will be a flight engraved at the end of history!" As he spoke, Ishii started the engine.

"The engine is working perfectly! The rudder works well! Ishii finally waved his hand to the three people standing in the observation room, and then drove the plane forward.

The plane flew into the sky with Ishii's hope and the blessings of the boys and girls.

"It's flying!" The girls exclaimed.

"It worked!" The boy said, looking at the moving planes in the observation machine.

"Na! Will Ishii succeed? Yuri asked.

"Who knows? If it succeeds, it will land in the city on the other side, and then you will either find someone to live there with, or you will have to live alone again. But I think it will go well! The boy replied.

The boys and girls stayed in the observation room for a while longer, and only then did they begin to go downstairs and get ready until they could no longer see Ishii's plane. At the teenager's suggestion, they stayed for the rest of the night waiting for the bracelet to recharge............

"What are you writing about?" Yuri asked Chino, who was lying on Ishii's desk.

"Nothing, just thought I needed to keep a diary............ Write down the plane. Chiho replied.

"The so-called history?"

"Probably! …… Okay, let's sleep! Chiho said to Yuri after writing the last few words.

"Yes! I'm going to set off for the west tomorrow! Yuri said as she looked at the map Ishii had drawn before leaving.

"Hmm!"

The two turned off the lights and quickly fell asleep............
