Fragment
After the zombie turned to ashes, Jake picked up the drops, which were a skill called Shift, quite a good skill as it could shift all other stats to a particular stat for a few seconds. He also found a paper with '7B' written on it.
Jake then came out of the building and showed the paper to Liliac, asking, "The key fragments are codes?"
Liliac nodded and asked back, "What did you expect? A primitive key?"
Jake opened his mouth to say something but then closed it and thought, 'Yes, why would I expect a key or such fantasy setting in a scientific + magic world.'
[Even I thought it would be something like a magical key fragment,] Nexus said in confusion.
'Fortunately, I am not alone,' Jake thought and then asked Liliac, "Where is my gift?"
Liliac nodded and then pointed her small finger at Jake. A light appeared at her fingertips and reached Jake's head and went inside it.
