How is this Sci-fi ranking calculated?

We count how many chapters readers actually open, then rank 100 Sci-fi novels by total reads since we started tracking. Nothing here is paid placement or editor-picked — the order comes entirely from reading activity.

How often does the Sci-fi ranking update?

The snapshot is recomputed every day at 03:00 UTC. The all-time board therefore shifts daily, and the ▲▼ arrows next to each novel show how far a title has moved since the previous period.

Are all these Sci-fi novels free to read?

Yes. Every novel on Lunovel is free to read in full, with no account required and new chapters added daily.
