I Open a Lock Shop in Chang'an

Travel back in time and become an unknown locksmith in Chang'an City during the Tianbao period of the Tang Dynasty. He has no system, no space, and even no extraordinary skills. Shen Du looked at his hands, which could only repair locks and match keys, and then looked at the countdown to the Anshi Rebellion - there were still three years left. Rice is expensive in Chang'an, so living there is not easy. He lowered his head and continued filing the keys. Later, a top-secret map was lost in Pinglu Jiedushi's house. The lock box was intact and the key was still under Jiedushi's pillow. Later, Yang Guozhong's treasury was stolen overnight, and the twelve chain locks were locked from the inside. Later, General Shu Han came to Xuanyangfang in person and asked for a lock on the small shop that didn't even have a signboard. "What's your name for this lock?" "It's called 'Where are the guests coming from?'" The young man wiped the copper shavings from his hands. "The lock cylinder has one hundred and eight pillars, and there are only two keys in the world. One is in the hands of the general." "Where's the other one?" "In the hands of those who want to kill the general." An Lushan received a box from Fan Yang. After opening it, there was nothing inside except a key. There are two words engraved on the key—— Chang'an. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
