" Battle Through the Heavens " was a very popular online fantasy novel. Currently, there were no online resources that were allowed by the edition to be read for free. However, some websites provided limited access to certain chapters, but the full version required payment. Some websites even offered trial reading of paid chapters. One could read some chapters first before deciding whether to buy or not. If you are interested in " Battle Through the Heavens ", I suggest you try looking for resources on these websites.
