After Chaldea Summons the Final BOSS

I am the last master of humanity At the fourth singularity point, after I loudly insulted the big demon king who was uncivilized everywhere and set fire to the world, I turned around and summoned him from the Chaldean Summoning Room. Although the other person looked gentle and elegant, I was not blind. If this wasn't the villain who just threw me into a nightmare, I would have eaten all the mapo tofu that Kali had stored. He shamelessly relied on the Heroic Spirit Summoning System to assassinate me! "..." "In the name of the curse, commit suicide, Cast..." A doctor who did not want to give his name but urged Solomon: "Wait a minute, ah, ah, ah, ah, ah, ah, ah, ah, ah!" After some time passed—— I am the last Master of Humanity, oh, it seems I am not the "only" Master now. Don't know why though. But the real big boss suddenly gave up on incineration, revealed his swaying blond hair and red eyes, and then swaggered to Chaldea and became King Solomon's leg pendant. The problem is that, for some unknown reason, this King Solomon always sticks to my side with great intensity and is inseparable. "..."

I will color it or change it after I finish the article. Purpose: Cherish life and swear carefully
