Knowledge Crystals II

There was nothing but the trash in the room; I am not disappointed, though. Me getting three knowledge crystals from it was already enough.

'I am going to use this crystal now.' I said in my mind, if I had found it outside the city, I would not have dared to use it till I found a place safe enough that no one could intrude, but it is different when I found it in the city.

In the past, many people had found the knowledge crystals in the city, which contain a map of the whole city and note the important area, treasury, and other things, those people were one of the luckiest people who had entered this Ruin.

They got complete information about the city, and through it, they were able to find treasures, inheritances, and other things from the city. Though thousands of years had passed and many of those things had withered to time, many of which had survived.
