Mr. Su Bai had seen the First Emperor, well, if relying on third-party perspective memory counts as having seen him;
He was a grand strategist, but now Mr. Su Bai is more interested in Emperor Alexander the Great, possibly due to the allure of mystery. After all, given the cultural differences and historical tendencies, most Chinese people are certainly more familiar with the First Emperor than Emperor Alexander the Great.
Moreover, that Emperor had taught the world how to "play" broadcast, calculated the coordinates of the next broadcast's world conquest and even roughly deduced the time for its relocation. It's clear that the First Emperor received the messages of that great Emperor and accordingly made arrangements based on this information.
This is a war that hasn't yet ended, a conflict lasting over two thousand years, and the final result will be decided in that world.
