On the first day of time travel, Li Gou Sheng saw the blood-red countdown on Huang Chao's head: July 13, 884.
He wanted to run away, but found himself trapped next to this hero who could not live for three years.
A cowardly delivery boy, a murderous leader of the rebel army - in order to survive, Li Gou Sheng relied on the golden finger of "seeing the probability of death" to pull Huang Chao back from hell again and again. From the fire-headed army to the dog-headed military division, from strangers to brothers in life and death.
He kept him alive for three more years.
Until the day when the death countdown reached zero, Huang Chao handed him the knife and said, "Gou Sheng, live for me."
The coward who originally just wanted to survive has gradually become his only brother.
