I returned to my car and followed Cao Fangyi into the base. The base is indeed very large, the roads are all new, passing through one warehouse after another, I do not know what exactly is placed there, there is no sign, only the number at the top of the door, warehouse number 1, warehouse number 2, I saw that there is no more than 21, and next to warehouse number 21
