Cultivating Immortality: I Can Scan All Things

Everything in the protagonist's field of vision can be scanned: its name, grade, material, function, origin, flaws, weaknesses, and opportunities. All become clear at a glance.

Other people cultivate immortality through insight, resources, or a master.

The protagonist cultivates immortality through an information advantage.

He scans a lost cultivation manual out of a junk pile, finds imperial green jadeite at a gambling stone shop, spots every hidden problem on an enemy before a fight, and scans a secret realm's entrance to find the routes to life and death.

From a ramshackle hut in a mountain village to the imperial treasury, the immortal sect's scripture library, and the Myriad Worlds...

There isn't a single thing in the Myriad Worlds that I, Lin Yan, can't figure out with a scan.

Tone: lighthearted, snarky wish-fulfillment. The protagonist is quick-witted and sharp-eyed, quietly snaps up bargains, and gets forced into face-slapping. Rapid-fire gratification and maximum gap moe.
