Princess Zhu Huan 3 plot problem

On the border between China and Myanmar, I suddenly heard the deafening sound of elephants. I saw the elephants of the Burmese army galloping by. I've never seen elephants fight. The Qing army was dumbfounded. Yongqi, Erkang and Xiao Jian are very careful. Erkang is fighting with Musha, the prince of Myanmar. Musha is petite but flexible. After playing for a while, Erkang was still relatively good, but Musha used hidden weapons to get out of trouble.
