I Came to Cultivate Immortality, and You Asked Me to Be an Undercover Agent

My name is Qin Feng, and I am an ordinary wage earner. I never expected to find myself in a harem game about cultivating immortals. I thought it was a Cultivation script, but I didn't expect it to be a Mission: Impossible script. Tianxing Sword Sect: "Xiao Qin, stay lurking in the Qingxin Sect. When the time comes, we will cooperate internally and externally to destroy the Demon Sect in one fell swoop!" Qingxin Sect: "Xiao Qin, stay lurking beside Lichen. When the time comes, we will cooperate internally and externally to destroy Lichen in one fell swoop." Demon Lord Lichen: "Fengfeng, help me join the Tianxing Sword Sect..." Qin Feng interrupted anxiously: "If you don't want to be an undercover agent, you can do whatever you want."
