Lin Chen is the son-in-law of the Su family who is looked down upon by everyone. Little does he know that in his dreams every night, he is learning the lost imperial medical skills and national martial arts from a mysterious man who calls himself the "First Emperor". When the family is in crisis, a killer attacks, and a terminally ill powerful man comes calling, he has no choice but to take action quietly, but he gets out of hand. It wasn't until the global dark empire "Twilight of the Gods" came to China, and he commanded three thousand "shadow guards" who practiced martial arts in their dreams on the top of Mount Tai, that the world knew that the ridiculed son-in-law had already inherited the most terrifying ancient inheritance.
