Some camp among the cherry blossoms when they are in full bloom.
Some taste tea and hold hands when fireworks burst in the air.
Some chew on ham sausages while staring at the rocket launch tower.
And when they chew on ham sausages, they discuss strange things.
Li Zheng and Lin Yujing sat side by side on the trunk, discussing the few metal frames on the sides of the rocket body.
"Hey, there are a few racks plugged into the rocket body there, what are they for?"
"Seems like there's white smoke coming out, could it be circulating cooling liquid?"
"Or injecting fuel? Isn't the fuel itself liquid hydrogen and liquid oxygen? Since it needs to be kept below -253°C, wouldn't it be more efficient to inject it just before launch?"
"I don't know about that..."
Li Zheng snickered and said, "Can you not handle it? Just this?"
"I can only look up information online," Lin Yujing bit off another piece of her ham sausage resentfully, "My mom doesn't tell me anything..."
