Assisting Liu Bei from the Three Offers of Xuzhou

In the first year of Xingping of the Eastern Han dynasty, time-traveler Zhang Yun huddles in a refugee camp in Xuzhou, his eyes fixed on a chat screen visible only to him. After his modern-day self finally persuades him that he has genuinely crossed into the Three Kingdoms era, Zhang Yun rapidly fires off a series of urgent inquiries: When did Cao Cao kill Bian Rang? What talents does Yuan Shu command? When did Dian Wei and Xu Chu join Cao Cao? When did the Chancellor go to Nanyang to farm? And how can saltpeter be mass‑produced in the Eastern Han? This is the story of transmigrator Zhang Yun, who relentlessly mines his present‑day self for intelligence while striving to make the Han dynasty great again.
