During these few rest days, Luo'er and others took time to aid Murong and others in training the soldiers, teaching them how to use firearms and modern tactics. Baiyue also helped to train those selected elves prepared to serve as scout troops, while learning Elvish.
The primary obstacle for the Earthling instructors and the Elven soldiers lies in communication issues as they often had to resort to interpreters. Consequently, the military had to teach those Elves to learn Tasta language. Although Luo'er and his companions' native language is Chinese, basically all instructors sent to Ilanadale can speak Tasta, so there is no need to specially teach these soldiers the difficult Chinese language.
Since reconciling with Luo'er, Luoya has finally been accepted by her mother, and Tangmo and the rest could no longer cling to Nina 24/7, which makes them quite unhappy.
