Flying had been humanity's most distant dream.
Back in the Ming dynasty, a man named Wan Hu had strapped forty-seven homemade rockets to a stool, held two large kites in his hands, and lit the rockets to launch himself into the sky.
Afterward, the people on the ground had witnessed a spectacular fireworks display.
The sight had been beautiful, with a hint of gore.
Only with the advent of hot-air balloons, airplanes, and rockets in modern times had humanity's dream of taking to the skies come true.
But... had it really?
Flying wasn't sitting inside a vehicle and admiring the scenery from above.
Soaring through the air with your own body-that was true flight!
Before the apocalypse, Shen Jin had also followed flying vehicles for personal use. For instance... he often watched the Iron Man movies.
He had done quite a bit of research on the subject, too.
Aside from that theoretical foundation,
while bypassing the firewall to browse Pixiv, he had also followed a few daredevil YouTubers. The foreigners in their videos had built similar jetpacks,
as well as wing-shaped jet-powered flight devices.
But... none of them were mature enough.
Shen Jin wanted to see what this intermediate Industrial [Jetpack] could do.
After struggling to put it on, Shen Jin discovered that he could equip and unequip it directly through his equipment slots.
It could instantly appear on his body, and he could put it away just as easily, switching back to his diamond armor.
It occupied the [Diamond Chestplate] slot, so he couldn't equip both at once.
Shen Jin tried wearing the [Diamond Chestplate] and then manually strapping on the [Jetpack].
He found that the armor was too smooth and hard for the [Jetpack]'s buckles to hold securely.
It was also incredibly bulky and seriously hampered his control.
