Matthew gazed briefly,
as if peering into the profound depths of the Multiverse.
Simultaneously,
a familiar sensation rushed towards him.
It was...
an exceedingly dangerous explosive signal!
...
Warning: You have discovered the legendary explosive "Ether Star Core"!
Ether Star Core: Once activated, this device can project a series of legendary spells originally burst in the Ether plane (Meteorite Annihilation, Malicious Distortion, Reality Remodeling, Destruction Beam, Chaos Calamity, and more) into reality, achieving a destructive explosive effect!
...
"You..."
"Are not a Summoner?"
A trace of astonishment finally appeared on Matthew's face!
Butterfly held the Ether Star Core aloft in the palm of their left hand, a faint smile spreading across their pale face:
"Now, allow me to formally introduce myself."
"I, Butterfly Ingram, am the honored chief resident of the Tower of No Illusion in the Cyberdragon."
"Of course, I am not a Summoner, but a legendary Machinist."
