Lu Wuxian traveled to another world, became an undercover agent, and obtained the undercover intelligence system. [Today's undercover information] [(1): Demon-slayer Li Xuan has just taken a concubine. The concubine is too enchanting, and Li Xuan's combat strength today is less than half of usual. [(2): Ding Feng, the traitor of the Great Zhou Dynasty, will go hunting in the eastern suburbs of Luoxuan City tomorrow. He does not have many guards with him, so it is a good time to kill him. [(3): A merchant ship is about to depart from Shiliuwan Pier to Dazhou at the end of the day. The merchant ship carries a huge conspiracy. If the host does not explore it, he will definitely regret it. [(4): As long as the host is in Luoxuan City, a warrior from the Demon Suppression Department will secretly follow you to keep track of your whereabouts at all times. [The system prompts that as long as the host obtains benefits that are beneficial to itself through intelligence, it will receive rewards. … During his long undercover years, Lu Wuxian killed demons, passed on information, and assassinated important figures. Every day I walk on the edge of exposure and death. However, with the help of the rewards continuously given by the system, Lu Wuxian transformed one after another, and finally overcome all difficulties and got out of the danger.
