The Cordoba V1.84, in the center of the third test site where the three of them stand, is the construct of runes. It looks similar to Cordoba's current appearance, but without the translucent heavy armor that looks quite substantial, or the gigantic staff that hangs on its back like a signature. There are many complex energy patterns exposed on its body, sparking with streaks of light, clearly indicating it is an unfinished semi-finished product.
"This thing is just a transitional tool, it's not possible that it would be put into actual use." Ruvie casually grabbed a piece of metal floating in mid-air, rapidly moving his hand over it while absentmindedly explaining, "I did my best to enhance the combat capabilities of the rune construct during the last upgrade, but I hardly did any work on optimizing the energy systems. Only managed to get around to that recently... Hey, little dove, you're supposed to be charging it with electricity."
