The Strongest Sage with the Weakest Crest 08 (manga)

Former Strongest Sage Matthias’s fight to protect mankind continues, with the demons launching all manner of attacks to destroy everyone with knowledge of their plot to weaken humanity through misinformation about magic!

Now the demons are out to manipulate the Dracopulse Lines—channels of hidden magical power flowing deep underground—for their wicked schemes, and Matthias is on to them! He makes for Maze City, which sits atop a massive dungeon and one of the all-important Dracopulse Lines. No doubt, this will prove to be yet another tale to add to Matty’s new legend!
