EPISODIUM
With new Zords and weapons the Rangers are starting to feel unbeatable, and are offended when RJ wants them to start refreshing themselves on some basic steps. However it soon turns out that the Rangers aren't the only ones who have been furthering themselves when they are soundly beaten by a more powerful Dai Shi before RJ comes to the rescue. Dai Shi captures him leaving the Rangers without a master. Then the Rangers go back to the Pai Zhua Academy and then Master Mao appears and sends them to the Spirit world to train with the fallen masters. As they arrive the masters take them by surprise and beat them while Dai Shi prepares for his fight with RJ.
