[Warning: Sexual content, lemons, comedy, MILFs, face-slapping, and a shameless protagonist!].....Creed Walden was a man of culture. Refined. Sophisticated. A true enjoyer of the finer things in life.Which was exactly why he ended up getting shot in the nuts.Who knew that messing with a gangster’s woman would lead to such unfortunate circumstances? One moment, he was enjoying the peak of pleasure, the next—BANG! Eternal darkness.But instead of fading into nothingness, he woke up… in a completely different world.A world he knew.It was the setting of a novel he had read ten years ago—a brutal, unforgiving wasteland where monstrous creatures roamed, and humanity teetered on the brink of extinction.The Apocalypse had begun.Here, humans awakened incredible talents to survive. Some became swordmasters, capable of cutting mountains in half. Others became mages, wielding fire and lightning at their fingertips. The strong ruled, the weak perished, and only those with true power could thrive.And Creed?He awakened… a summoning ability.Not bad, right? He could call forth mighty beasts, legendary heroes, or divine warriors to fight for him!At least, that’s what he thought.Until his first summon appeared.A gorgeous, sultry woman with horns, bat-like wings, and a very inappropriate outfit.A Succubus.It didn’t take long for Creed to realize the shocking truth—his summoning ability could only summon Succubi!The apocalypse was raging. Civilization was collapsing. People were awakening godlike powers to fight for survival.And here he was.Surrounded by beautiful, seductive demons who thrived on… other kinds of energy.Creed leaned back with a grin, his eyes gleaming with a mix of amusement and wicked excitement.“...Well, I suppose there are worse fates.”
