Honestly, it's hard to find a completely reliable app for free manhwa. You might come across apps like MangaZone, but there's no guarantee of the legality or the frequency of updated content.
There were many apps that could be used to read free literary novels, such as:
Qidian Chinese Network: A well-known literary novel reader with a large number of free literary novels, including fantasy, urban, historical, science fiction and other types.
2 : A novel reader created by the company to provide free novel content to support online writing and reading.
3. Simple Books: An online reader with a theme of literature and creativity. There are a large number of free literary novels. You can find various types of novels here.
Douban Reading: Douban Reading is a literary reading that provides free and paid novel content, which contains a large number of classic literary novels.
5. Palm Reading: Palm Reading is a well-known online reader with a large number of literary novels, including fantasy, urban, historical, science fiction and other types. There are also many free literary works.
The above apps are just a part of it. There are many other apps that can also read free novels. You can choose according to your preferences and needs.
Webtoon is a popular option. It has a variety of free manga and comics. But keep in mind that the selection might be limited compared to paid services.
I'd recommend Tachiyomi. It's a popular choice among manga readers. However, make sure to download it from a trusted source as there might be unofficial or modified versions that could pose security risks.
You can use Qidian Chinese website's Qidian Reading App to watch the complete works of the novel "Celebrating Years" for free. Qidian Chinese Network was the platform for the novel's serialization. The readers could choose to read some chapters on the website or pay to read the entire novel. In addition, the Qidian Reading App also provided free reading services for novels that celebrated the past few years.
