Upon hearing Wu Song's words, Lu Yu narrowed his eyes slightly, then looked at the box in Wu Song's hand in front of him, with a hint of confusion in his eyes.
He had encountered this method of anonymously sending packages more than once or twice before, but they had always been in the form of letter packages, whereas sending boxes like this was a first for him.
In an instant, a sense of alertness surged within Lu Yu's heart!
"Wu Song, you step outside."
Thinking of this, Lu Yu spoke, "When you go outside, make sure you close the door behind you!"
This time Lu Yu didn't ask about the courier's information because he knew that there was simply no need to ask.
Since the other party would anonymously send him such a box, it indicated that they would not reveal their identity, so trying to track down the courier was futile.
And upon seeing this box, for some reason, an extremely dangerous feeling suddenly surged from Lu Yu's back, which is why he had Wu Song step outside early.
