If you change your clothes and change your name, it's really hard to find someone without leaving your contact information! If you know which district he went to, I suggest you start with the sect and see if the equipment signature has been changed. Yuan soul bead is also very different. If he changes all these things, I think it is meaningless for the landlord to find him unless he is your real friend. Here, if he is your friend, there should be a clue to the contact information. The above suggestions are for the landlord, I hope to adopt them!
