My best friend and I, both civil and martial arts/dancers, accidentally traveled back to the Tang Dynasty, saw Yang Guifei dancing gracefully, and showed Latin dance to the imperial concubine; we talked about poetry and life with Li Bai, and introduced Su Shi's poems to him... We not only smashed the conspiracy, but also went to the battlefield to kill the enemy and serve the country, and finally gained a beautiful relationship, and the best friend became a mother-in-law...
