After cleaning the upper floor of the library, Xia Fei went down the basement with the two keys in hand.
There were two rooms in the basement. There was the room on the left with the rare book on the introduction to robot coding stored inside, which Xia Fei already knew about, but he had no idea what was in the room on the right.
The robot coding book was priceless, and Qin Mang allowing Xia Fei to clean the room meant that he trusted him now; he would not entrust him with these incredibly important keys otherwise.
Xia Fei headed into the room on the left first to give it a good cleaning. The room was just as before, with the massive glass cabinet standing right in the middle of the room, where the heavy book resided.
After shutting the door, Xia Fei came to the room on the right. It was of a similar area to the previous room, but it was obviously messier, stocked with plenty of old tables and stools as well as many other things.
