I Lived in Seclusion for Three Years, and My Inventions Shocked the World

[System + livestreaming + cutting-edge technology + farming + everyone-misunderstands-the-protagonist]

Su Yun lives in seclusion deep in the mountains and is bound to the Divine Craftsman System, but his perception is seriously skewed!

What he sees as scrap metal is actually aerospace-grade shape-memory alloy;

What he sees as a children's toy is actually a military quadruped mech;

The glass marble he casually polishes is actually the core lens of a lithography machine!

Then one day, his money-loving younger sister, Su Xiaowan, secretly starts a livestream to expose her brother's “lazy life.”

But the stream soon takes a wildly unexpected turn

As Su Yun carves patterns into a rusty iron ball with a file,

the big shots in the livestream room fall to their knees: “Stop! That's a tactical nuclear warhead! Don't hit it, it'll blow!”

Su Yun calmly waves them off. “Don't panic, folks. It's just a giant firecracker I made. It'll make a nice bang.”

As soon as he finishes speaking, a mushroom cloud rises at the entrance to the village.

Military forces around the world go mad: “You call that a nice bang? Your firecrackers can punch through the atmosphere?!”
