Espionage: The Ghost of the Beiping Bookshop Awakens the System

In 1942, at the Yaohua Bookstore in Dashilan, near Zhengyang Gate in Beiping, Su Yu was crouched behind the shelves wiping glass. He'd only taken over the shop five days ago. Then the System chimed: Sign-In System activated! Day One sign-in reward: ten AK-47s and fifty thousand rounds of ammunition! Old Chen slipped in wearing a short jacket and suddenly drew his gun. I sprang up and dropped him with three shots. From then on, a legend spread through the world of espionage: there was a bookstore owner in Beiping who could make weapons appear out of thin air! The Japanese started patrolling the streets an extra couple of times! I crouched behind the counter, munching on the ration biscuits from the sign-in reward. Don't rush! Let me sign in for thirty days! Then every cop in the city will know that this bookstore isn't easy to walk into!
