HolyDragon17 you don't need a lawyer to review it. just read through it a couple of times-- it's not too hard to understand if you have decent english skills. also, the editor who contacted you about the contract will also be there to answer any questions, so the entire process is fairly easy!
the contract can be good or bad, depending on what your motivations/goals are. if you loooveeee your novel, your characters, your plot, and you will be eternally sad if you had to sacrifice any of it, don't sign the contract. the contract says that the novel can be picked up by a secondary author hired by webnovel if you drop it, that webnovel can make suggestions for your plot, and that if you write in the same world, the book must be also under the contract. (the good news is that half the things they say on the contract as "consequences" won't actually happen. if you drop your novel but you barely earn them any money (aka not a top author), webnovel's not inclined to put in the effort to hire a secondary author. and also, you're allowed to take as long hiatuses as you want, without consequences, except for not being paid, obviously)
so, if you write your novel without too much attachment to the work, then the contract is awesome! you can get an opportunity that no other beginner novelist can be given. it's really a good contract for beginners who are looking for experience, to improve, and to earn a little extra money on the side.
and yes, after you finish your novel, you will still earn revenue depending on the readers still reading.
it's basically a contract that can't be defined by good or bad. it all depends on how you feel as an author to your work.
for me, I signed it b/c although I love my characters and plot, it's not the end of the world if I have to give it up. I have 20 more ideas and characters (literally) waiting for me to write lol.
