They Asked Me to Go Undercover!

If it breaks down, I become a human being who infiltrates a mysterious undercover; if it breaks, I become a weird undercover agent who infiltrates human beings... My name is Lu Chen, and I have traveled to a strange world where there are strange beasts from the Classic of Mountains and Seas, monsters from folklore, and archangels from Western mythology... Here, most of the supernatural creatures exist in human form. What if your head falls off? Don't be afraid, just pick it up and match it again. What, are you human? Sorry, I wish you a good pregnancy in your next life. My name is Lu Chen, number RMWS1314, and I belong to the Dragon Kingdom 404 Mysterious Bureau. I thought I was human, but they called me "Strict Father from Hell".
