Chapter 517 - Chapter 517 Tangyu's Guess

Outside the private room, in the bathroom, a male waiter in disguise stood coldly, his gaze vigilant as he scanned his surroundings. Any slight movement could not escape his eyes. He held a mobile phone in his hand, sending a message out. After sending the message, he dismantled the phone, destroyed the SIM card, and then threw the phone into the toilet. Having done all this, he checked the time, a cold gleam appeared at the corner of his mouth, and he walked out towards the private room where Tangyu and his party were. First, he pressed his ear against the door to listen to any sound inside. After listening for a while, a smug smile spread across his face. He knocked on the door.
