Su Yao, a graduate student in the Department of Archeology, touched a Tang Dynasty bronze mirror without 3C certification at the excavation site. Her soul traveled to the first year of the Tang Dynasty, and exchanged bodies with the Turkic princess Ashina Yun. She woke up and lay in the Turkic tent. The first thing she said was "Sorry, I don't speak a foreign language." At the same time, the real Ashina Yun was performing Turkic obeisance to Luoyang at a modern archaeological site, and was diagnosed by his tutor as "being obsessed with writing the thesis."
Su Yao stepped into the Chang'an court as a Turkic princess and blurted out "Hello, aunt" when she saw Wu Zetian for the first time. She used modern debating skills to silence the Turkic envoys. She used a hollow phalanx to repel the enemy on the Lingzhou battlefield, held up a tin loudspeaker to persuade surrender in Turkic language, and used a bowl of vinegar in the East Palace to expose the cyanide poisoning case. Pei Yan, the master of Tianji Pavilion, said "I am just here for the bronze mirror", but he started from secretly sending candy to the Imperial Ancestral Temple, to breaking the spiritual core into pieces in front of Hanyuan Palace to seal the space-time rift - he protected her with his life every time. In the modern world, Ashina Yun tamed cars like fierce horses, split quantum computers with Turkic battle axes, and finally purified the remnants of the Xuanming Sect in the two worlds at the cost of his own blood.
