The cultivation of fruits and vegetables was also a method passed down by their ancestors. To preserve the nutrients, they mostly ate them raw. Even so, the yield of those fruits and vegetables was limited, far from enough to feed the entire galaxy's inhabitants. The residents of their galaxy still had to rely on absorbing energy stones to replenish their energy. According to their galaxy's logs, there was a time when their ancestors developed nutrient fluids, which later evolved into absorbing energy stones. Unexpectedly, this woman before him had a large quantity of fruits and vegetables. And this kind of flavor—he had never tasted anything like it. At that moment, he seemed to understand what she meant by "boring." "What can I trade with you?" Shen Yunyun said, "I want rare things like laser guns, storage rings, and flying vehicles." "Easy. I'll give you a laser cannon, three laser guns, a storage ring, and a flying vehicle in exchange for your super energy stone, plus all this food. Deal?" Shen Yunyun paused for a moment. The value of what they each possessed was unequal in their respective worlds. So there was no point talking about who was taking advantage. "Of course," Shen Yunyun said, immediately taking out the stone. Karl handed her a brand-new storage ring. Shen Yunyun put the ring on her finger and, following Karl's instructions, reset the password in her mind. She entered the storage space and saw the laser cannon, laser guns, and flying vehicle inside, then asked Karl to teach her how to use them. A laser cannon—she probably wouldn't need it. The laser guns were only for emergencies. As for the flying vehicle, she wasn't sure if it could be used. She'd heard that drones flying without prior approval would be shot down. Karl taught her how to operate the laser cannon, laser guns, and flying vehicle. "What if the energy runs out?" Shen Yunyun asked. "You know the sun, right?" "I do. Don't tell me that when the laser gun runs out of energy, I just need to leave it out in the sun?" "Yes. When our weapons run low on energy, we take them to the solar system to recharge. There are people specifically in charge of that." Shen Yunyun was silent for a long time. Interstellar products were bound to be high-tech, but not to this extent, right? This was the real deal—new energy. She looked at the flying vehicle again. It resembled a child's hover scooter, completely different from any flying vehicle she'd seen at airshows. "Is this solar-powered too?" "Yes, to be precise, it absorbs a certain type of ray from sunlight." Shen Yunyun nodded, half-understanding, and continued studying the flying vehicle. Karl had already summoned a robotic dog, which carried the stone away. He stood beside Shen Yunyun the whole time, watching her fiddle with the flying vehicle without saying a word. Shen Yunyun then remembered she hadn't given him the spicy sticks she'd promised. So she rummaged through the basement, pulled out two packs of spicy sticks, two packs of crispy noodles, and some cookies, and gave them to Karl. Karl was pleasantly surprised. "If you get more good stuff in the future, we can trade again." "Okay." Shen Yunyun returned to the basement with a full haul and stored everything inside the storage ring. The storage ring had a massive space—more than ten times larger than her basement. With this storage space, she no longer had to worry about her treasures being stolen. She planned to have some shelves custom-made later, so she could organize things by category for easy access. She went over her other wishes, saw that it was still early, and decided to check on the apocalypse big shot.
