Don't Mess with the Bookstore Owner, There's an Abyss Inside Him

Fifteen years ago, Chen Mo woke up from the ruins with a baby in his arms and no memory. Today, fifteen years later, he is the owner of a second-hand bookstore, repairing books, cooking noodles, and raising his sister every day. Until someone came to the door and said: "Under your bookstore, the gate to the world was suppressed." The purple moon is in the sky, the seventh node is about to open, and the two worlds are about to be connected. [Yuan] swallows all things, [Wedge] suppresses order. Chen Mo opened the accounting book: Today's expenditure is to suppress the tide once. Income - a bowl of noodles cooked by my sister. A whisper came from behind the door: "Why don't you let us back?" Chen Mo raised his eyes. The door can be opened, but you have to ask my permission first.
