This link is from Webnovel.com, a known scammer. They prey on fantasy authors, looking to hook them up to horrible contracts and allegedly attempt to steal their IPs. Even if you get a non-exclusive contract, what they are looking for is to exploit your work and give you as little money as possible, because they know that most web fiction writers are young and inexperienced with legal matters.

This post is a very good resource that discusses the various web fiction companies commonly considered scammers, and provides several links to the types of shady stuff Webnovel itself does. This isn't even to mention its alleged censorship of anything critical of CCCP, which is probably a deal breaker for many writers all on its own.
The most important thing to know is that the person who sent this message did not read your book. They have no idea if your story is any good or not, and that alone is extremely suspicious.
Friends don't let friends use Webnovel.
In fact, friends should actively tell friends to avoid Webnovel at any point possible, because it can really hurt your writing career early on, and every dollar they get from your stories is another dollar they can use to recruit even more authors.
