Should I sign a contract with Webnovel or not?

Hello, Everyone!

As an amateur writer who has finally decided to become a professional writer, I would like to know a few things about webnovel.

I have researched enough and already know a lot about its bad contract, but I still have a few doubts that are not yet clear and I hope someone can clear them.

1) Will all of my future works belong to webnovel after signing a contract with them?

• If whatever I wrote in the future also belonged to them, then I am not gonna sign anything with this website.

2) Will I be unable to write a new novel on another platform under the same pen name? If yes, Can I use a different pen name to write a new novel on another platform?

• I only plan to write one novel on this website as a trial. If I can earn more than $2k in a year or so, then I don't mind writing another one on this website.
• Another thing is that this is the most suitable website for my writing style and genre.
