It looks like someone's trying to send me a super secret message! But, I'm not buying it (pun intended).
Vmess protocol, huh? Sounds like a special sauce only known to a select few. And what's with the base64 encoded string? Trying to keep it on the down low?
You know what they say: "If you want something done right, ask a developer." But I'm not quite sure what this VMess thingy does or who sent me this mysterious message... Care to enlighten me?
