The first entry is always the pin's source. Overall confidence is a weighted average of how firmly each reference supports the start and end times used above; a reference counts half as much for every 180 days older than the newest.
Estimated: iQIYI has not announced a date. An entertainment blogger reported on 11 August 2026 that the series is pre-scheduled for late October, and a 23 September Weibo[4] post repeats 'late October at the earliest' and says it has passed review; both are unconfirmed. Earlier guesses of a second-quarter 2026 release after the April trailer did not happen. This uses 30 October 2026, about 10 months after the 15 December 2025 wrap. Re-date once iQIYI announces the date.

Something missing or wrong? Say it in your own words: a link that backs this pin up, a different start or end date and why, or a fact it lacks or gets wrong. The AI checks it against this pin's sources, searches for better ones, and adds any page that backs you up. The pin's own sources still count most. A picture that shows something else, or shows it badly, is looked at too, and moved down or replaced.
