This clumsy method was theoretically feasible, but to succeed, it had to meet a prerequisite — it could not be disturbed by the outside world.
Emperor Qin Shihuang could not let other cultivators know where he was and could not be frequently disturbed.
Otherwise, if his hibernation were interrupted time and again, how could he "travel" to the future?
Thus, he thought of the "Soul-shielding Stone".
The "Soul-shielding Stone" could completely shield the perception of a cultivator's Divine Sense (also known as spiritual power). During the Warring States period, many assassins, such as Jing Ke, stirred up chaos by relying on this special stone.
After unifying the country, Emperor Qin Shihuang, for the peace and stability of the nation, forcibly collected all the "Soul-shielding Stones" in the country, totaling hundreds of thousands of pieces.
