Why can't Duan Fei, the best country doctor, see it?

Duan Fei, the best rural doctor, can't see it for the following reasons:

1, the second half of the novel needs to be paid, so you can't read it without buying it.

2, the novel has no cache, and there is no internet access when reading the novel, so it can't be opened.

3. The novel finds only one or only a few novel sources through the bookshelf, and the novels from these sources are not fully updated.
