Poison Blade

It took me a while and an hour into my Inheritance Space to came out of the thoughts of the fourth Grand Art. 

This is world shocking news; it would especially shock the Wisdom Tower, which had been treating this precious art like common art that everything in the Wisdom Tower could take with few merit points.

It is due to being a Grand Art; it had not been discovered. Grand Arts could not be practiced by anyone; one needs to have an affinity with them; otherwise, there would not be only one or two people every century learning them.

I shook my head off the thoughts of art; I have already made the notes about my observation, and I will study them in leisure, now I should focus on my mission. Which is patrolling the area I am assigned, killing the Grimm Monsters I have found, and see if there is something strange going on; if there is, immediately inform the higher-ups.
