Webnovel employs multiple people who are sub-contractors, trying to bring in authors for WN. Here is one example, as they are plainly offering others who are on the site to bring in people:

Anyway, the thing is, it is probably not a scam; I mean, the message you received.
I was also poached a few times already, but every time I asked for contract details, I disliked them a lot. I had a thread about when it first happened. Here:
Don't fall for it, guys and gals. That part is the most insidious. Of course, this only stands if you care about it; if it is not that important, you just want to grab the bag, no issues then. But losing your ownership over digital distribution is the biggest catch, even if they try to word...

So, if you accept it, make sure you read through the contract because it has harsh requirements if you do care about your IP. Of course, that is the price you pay for being supported; I get that but also consider that hundreds of others take the same deal as you. WN will only truly start propping you up, if you pop off, otherwise, they will bury your IP in their dragon stash, forgotten forever and you won't own it anymore.
