He retracted his skinny legs, and after a moment, he reached out to grab the broken wooden door. He twisted it back and forth for a moment and removed a few pieces of wood.
A little boy in tattered clothes crawled out from the opening and knelt on the mud-covered ground. His face was almost touching the ground as he whispered into the room, " "After I leave, find something to block the door. When I find something, I'll knock twice, then pause for a moment and Knock Three Times. Remember, if it's not this knocking sound, don't open the door."
The pair of bright eyes in the room blinked, but did not speak.
"Now, seal the door again."
The pair of eyes inside suddenly disappeared, and a moment later, there was the sound of heavy objects moving with difficulty, filling up the fresh big hole that had just been smashed.
seeing that the wooden door had been blocked again, the little boy heaved a sigh of relief and got up to walk outside.
