Lin Ye transmigrates to the Naruto world and becomes a handyman in Konoha who can't even get into the Ninja Academy. With mediocre aptitude, he's constantly bullied. Then one day, he unexpectedly awakens the "Omni Extraction System," which lets him extract abilities from anything he touches. Brush against Sasuke's clothes and extract "Sharingan (Basic)"; bump into Naruto and extract "Nine-Tails Chakra (A Trace)"; even step on a statue of the First Hokage and extract "Wood Release Cells (Weak)"!
From then on, the handyman boy rises against all odds:
Ninjutsu? He can extract and copy it with a single glance, faster than Kakashi!
Taijutsu? The stronger the enemies he beats, the more outrageous the taijutsu experience he extracts!
Kekkei Genkai? Byakugan, Rinnegan, whatever you've got, he'll grab it as soon as he touches you!
From a ridiculed handyman to knocking out a genius ninja with one punch, then single-handedly flattening the Akatsuki, and finally standing at the summit of the Shinobi World, Lin Ye has just one thing to say: "Don't mess with me, or I'll strip your ancestors of every last one of their abilities!"
