When writing a novel, is it better to write it online or submit it directly?

I personally think it is better to submit directly. Last time I had a novel, about 200,000 words, and I posted it to Qidian.com, but before it reached 10,000 words, the editorial department had to give me an A sign. You also need to sign a literary work transfer contract. Although Qidian.com is a relatively good platform, it is all signed A, which means that you need to transfer all ownership of your entire book. Electronic copyright, physical publishing copyright, etc. I just wanted to sign the electronic copyright transfer, but that didn't work.
