Leshan Grand Buddha to Emeishan Baoguo Temple

Hello
I would like to go from Leshan Grand Buddha to Emeishan Baoguo Temple. The fastest but most expensive option is a taxi, which takes about 1 hour. I could not find a direct bus. Only bus 302 and then bus 602 or 601, but the bus takes more than 2 hours. And the train is not that much quicker as you first have to take the bus to Leshan Station and then the bus from Emeishan Station to Baoguo Temple, which also takes another 2 hours (including the time buffer at the station). Is there another cheap alternative?
Thank you very much for your answer.
