Why? Because two (S-) ranked creatures got turned into mere ashes—their circular mana cores rolling on the ground.
'Hmm…as I suspected, my earlier attack was too strong so even the so-called core was destroyed…good thing I slightly held back…'
Hearing Zeth's telepathic murmurs, Shye's eyes almost popped out of their sockets.
'Y-You still held back?'
'Yes, Master Shye, as I wanted to see the mana core that everyone in my world talks about so much because it rapidly increases our strength as familiar spirits.'
Meanwhile, the ambushers were panicking.
'Sh*t! Sh*t! How is this familiar spirit so strong?! Wasn't it barely a King-class? If so, then three (S-) ranked monsters should have sufficed!' The assassin leader inwardly thought in utter frustration.
