Su Zi'an activates a System that lets him open time-space passages to parallel historical worlds. Different dynasties, different famous figures, different cultures: what sparks will fly when past and present collide?
In 626 AD, Turkic forces are at the gates of Chang'an, and Li Shimin is about to suffer the humiliation at the Wei River.
Li Shimin: "@Su Zi'an, I implore the Immortal Su to save me!"
Su Zi'an: "The Qin Empire's elite troops, the Han Empire's iron cavalry, the Song Dynasty's Yue Family Army, the Ming Dynasty's Divine Machine Battalion. Is that enough?"
Sun Simiao: "@Hua Tuo, this junior would like to ask you about your skull-opening technique. Would that be all right?"
Su Zi'an: "@Hua Tuo, @Sun Simiao, @Zhang Zhongjing, @Li Shizhen, why don't you hold a lecture on traditional Chinese medicine? You can learn about Western medicine too. I'll livestream it!"
Li Bai: "@Li Qingzhao, little Qingzhao, want to drink?"
Su Zi'an: "@Li Bai, quit flirting! I heard tens of thousands of your poems have been lost. Hurry up and write them down!"
Students all across the country: "I thank you through gritted teeth!"
Some big shot: "Any emperors interested in doing business? Sweet potatoes, potatoes, tanks, and cannons, we have it all. Bring oil and mineral resources to trade!"}
