Traveling through a world with historical gaps, Lin Yu has become a laughing stock in the academic circle for fabricating "ancient history" and is about to be expelled.
In despair, he activated the [Across Time and Space Lecture Table] and was able to connect to the Qin Dynasty two thousand years ago!
In the first lesson, he taught Qin Jun how to make Baili Steel.
The next second, a modern archaeological team dug up a Qin Dynasty steel sword outside the school, with the inscription "Industrial Experimental Institute" shocking the world!
Facing global doubts, Lin Yu smiled slightly: Don't worry, this is just the beginning.
Next, I want to tell the First Emperor what calculus and ballistics are!
What you dig out will be a miracle for the entire civilization!
