Infinite Summon Fusion

Steam robot, demon of the abyss, daughter of time... Infinite summons came out of nowhere, and Da, who was reincarnated into a different world, was the first man in history who could fuse and become stronger. In theory, he could fuse with any summoned creature. Gods, dragons, and humans, this is an era where demons and monsters coexist. On this stage, Da will create an epic in history.
