The Familiar Elder Sister
The elder sister just shook her head and lifted her right hand as she rubbed the spatial ring that was on her finger, "Grandpa, this is the spatial ring you gifted me but do you recognize this?"
"That..." Agis Stirlander suddenly widened his eyes, "Is that the 'Explode' Symbol!?"
Agis Stirlander recognized this symbol very well as this was rather a popular Inscription Symbol used for various purposes, even festive purposes. However, those 'Explode' Symbols that were used for festivities were generally at lower grades.
The engraved Inscription Symbol that the spatial ring has is undoubtedly at the Sky Grade.
The elder sister nodded her head, "That's right! If someone stole my spatial ring and removed my blood connection with it, then the spatial ring will explode but since this is a High-Level Sky Grade Spatial Ring, the resulting explosion will instead cause an implosion, causing the objects within to be lost in unknown space."
