The first episode of " Return of the Undercover " had a high viewership rating, but the second episode had been delayed for a long time. The reason was more complicated. The director and screenwriter of the first film had yet to decide whether to continue filming the second film. There were some rumors that the second movie might unfold in a similar way to the first movie, but the details and plot have not been confirmed. The producer and director might have to weigh the cost and benefits of filming the second film. If the ratings for the second film are not as good as the first, the producers may face greater financial pressure, so they may need to carefully consider whether to continue filming the second film. The copyright issue was also a factor. If the copyright of the first film had been sold, then the second film might need to be re-earned. If the rights to the first film had not been sold yet, the producers might have to wait for a while before considering shooting the second film. In short, whether the second episode of 'Return of the Undercover' could be broadcast depended on many factors, including the plot, cost, revenue, and copyright.
