A Thief’s Night!

Ace instantly vanished from his spot before storing this demon's storage ring, crimson broad sword, and silver-blue shield. 

Surprisingly, he wasn't going toward his hideout, but moving in the completely opposite direction!

Ace left the corpse of this Nāga behind, so the approaching crowd could easily find him. 

If he wanted he could've just destroyed or stored, this Nāga's body to get rid of another time, but he didn't do so because he wanted the others to find out and this will probably cause some trouble for the Demon King behind this Nāga fellow. 

Because there weren't many races like Nāga on the mighty demon continent, it would be easily discovered who this Nāga was subordinate to once someone with authority started to investigate. 

Although it wasn't enough to harm a Demon King; it was enough to cause tensions between two Demon Kings and inflation suspicious about why this spy acted so boldly in another Demon King's territory.
