After Wu Shaochen finished sending the message, he enabled private chats from strangers...
He had turned off this feature back when he killed the first BOSS, the Boar King, in the Novice Village, and hadn't turned it back on since.
Now he had no choice but to enable it, otherwise, people wouldn't be able to contact him...
However, once he turned it on, Wu Shaochen was immediately overwhelmed as messages flooded in non-stop.
