Unable to Parse Chapters

I am trying to scrape WuxiaWorld.Site. The method used is WordPress default (though Puppeteer works with some working). There are two issues with both WordPress and Puppeteer. 1. For some novels, chapters are not scraped at all. 2. Images (featured images) are not pulled from the website. Please check the attachments. Another problem: Though I have a scraping rule set for both NewNovels.org and WuxiaWorld.Site, the plugin is conveniently skipping the tasks for NewNovels.org and focusing only on WuxiaWorld.Site.
