Tenali Rama's Letter

Shradha finds a letter written by Tenali. In the letter, Tenali states that he is going to meet Dhananjay. A similar letter is sent to Krishnadevaraya and he learns that Tenali has risked his life to resolve the differences between the two states. While on the way to the neighbouring kingdom, Tenali meets Tathacharya. How will Tenali and Tathacharya prevent the war from happening?
