I, Guiguzi, Teach Ying Zheng to Unify the Six Countries at the Beginning

I was sitting in front of the computer catching up on DDL, and the traffic outside the window was flowing as usual. Until I opened the out-of-print "Guiguzi", a simple jade bottle rolled down from the pages of the book. As a social animal, I laughed at this poor antique craftsmanship, swallowed the "Liuwei Dihuang Pills" in the bottle, and continued to work on the PPT. However, the next second, my whole body was in severe pain. When I opened my eyes again, I saw a child in ancient costume being besieged. He turned around and shouted: "Sir, save me!" - Those features and eyes were actually the boy Ying Zheng from the textbook!
