Given how things usually go, the metal clone will probably gain self-awareness, steel shuhangs life bound treasure, and fight off the tribulation with the city or the big giant Mech...piloted by it, a mini mech.

Will shuhang be able to get rid of the Doudou-mobile and get an actual ship customized for him, or will it survive in some unforseen way to stick around and haunt him? My bets are on the latter, but I guess we’ll see.
People have 10 tribulations to become immortal but Daddy Song is playing with tribulations on a regular bases... When he reaches the immortality stage he would have had over 50 tribulations...
When the cards are down you know you can count in Song "I am a Master at Transcending Tribulations" Shuhang. See how selfless he was and saved that little dog. =D
