"Is this an invitation letter to Lin Group's banquet?"
Mo Yan took the letter and looked through it. The wax seal on the back of the invitation letter had been completely removed. It was probably not Li Guoguo who opened it, but the invitation letter had been opened before it was delivered.
"Where did you find this?" Xu Tian asked Li Guoguo.
"On the ground. I noticed it when I closed the door."
Mo Yan's eyes darkened. "Let's go check the surveillance cameras."
The three of them went to the front desk of the hotel to explain the situation. The manager didn't want to help them check the surveillance cameras, but Xu Tian was too strong-willed. Only then did the three of them see what had happened. Someone in the uniform of a hotel employee sneakily stuffed the invitation letter into their room through the crack of the door.
