Scavenging at a Junkyard, What Does Finding an Aircraft Carrier Say About Me?

Zhou Mo inherits his grandfather's junkyard and binds himself to the [Everything Upgrade System], which can turn any piece of scrap into top-tier gear. On the first day, he upgrades a rusty kitchen knife into a [Vibranium Tang Dao]. On the second day, he upgrades a broken radio into a [Quantum Communicator]. On the third day, he upgrades a scrapped Santana into a [Transforming Mecha]. He posts short videos online, and the viewers crack up: "That special effect isn't worth more than five cents!" "Hey, streamer, why not find an aircraft carrier next time?" Zhou Mo replies seriously, "I'll go check the port tomorrow." Sure enough, he finds a rusty submarine hull in a scrap heap. System notification: [Can be upgraded into a Borei-class strategic nuclear submarine] Zhou Mo spends three days completing the conversion in his own backyard.
