Marvel: Taking Multiverse Gigs to Earn Ability Traits

[No Brainless Power Fantasy + Progressive Growth + Marvel + Warhammer + DC]

My name is Lu Wen! I've transmigrated...

Now that I've transmigrated, surely I get to defeat the Demon King, become a noble, marry a princess, and reach the pinnacle of life!

But then the system tells me its previous 526 hosts all died. It hands me an app straight out of a secondhand marketplace, lets me take gigs across dimensions and set my own prices for selling ability traits-and says it'll fire me if I don't meet my KPIs?

Fine. Not exactly a dignified entrance, but I'm already here, so I might as well make the most of it~

I've fought Deadpool over toilet paper, given Superman a perm, and knocked a Titan upside the head. I've settled trouble for devils and fought battles for angels! I've swiped Senzu Beans and snatched Talismans, and in a bit, I'm off to Terra for another fight~

Wait. Which fucking Terra is this?! (Oh, shit~ I've stumbled into the Corpse-Emperor's recruitment drive!)

My adventures along the way are a little hard to explain. Some people call me a good guy, others call me a bad guy, and some say I'm just a complete dumbass! But none of that matters. What matters is that I survived! I didn't become predecessor number 527 for the system's next host to hear about!
