Diary

Han Sen was very eager to read the contents of the diary.

Although it was a diary, the entries weren't dated. And furthermore, each page only contained a sentence or two. The entries were not a continuous thing, either. It was a casual, random recording of stuff.

"3480, why is he so dumb? I can't believe he got killed by a Jade Bone Beast."

"Has 5079's brain filled up with water? With his power, he might as well have a death wish by going to the Galaxy Sea."

"He died. What a dumb*ss."

...

The diary was full to the brim of complaints, but Han Sen wasn't sure what the numbers meant.

"Are the crystallizers practically the same as humans? Were they in the sanctuary to hunt creatures? Are the numbers the names of their friends?" Han Sen thought to himself.

There were many complaints, but Han Sen made sure to read every single word. He didn't want to accidentally skip over an important detail and lose a potential lead.
