At night on the foggy border, Gao Xuanxuan and Fan Xinxi were involved in a life-and-death situation in a national war disguised as "terror." Weird disasters keep taking away clues from your companions, but the enemy uses live broadcast-like rules to guide the hunt. The two are forced to join forces, from deciphering restricted area symbols, countering supernatural traps, to igniting signals for counterattacks on the battlefield. The deeper they go, the more dangerous it becomes, but as long as they join forces, they can turn death into a bargaining chip, and they will have a great time, and they will be overwhelmed.
