My Bro-Girl Friend Reincarnated as a Succubus. What a Lucky Break!

Chen Feng has a childhood friend who grew up with him, a girl he treats like one of the guys.

When he turns eighteen, awakens his class, becomes a Dark Summoner, and performs his first summon, he never expects...

To summon the very girl who, after awakening early two years ago, was admitted to a prestigious academy, right to his side.

"Today is important. For a succubus, it's a once-in-a-lifetime chance to advance."

"We've known each other for so long. You have no reason to refuse this tiny favor, right?"

"Good girl. Do as I say and leave everything to me."

After that, Chen Feng develops a taste for lamb kidneys.

Lei Mu is fortunate enough to awaken a System.

But...

"What the heck is a Self-Sacrifice System?"

"You sacrificed billions of living beings and received one golden summon."

"You sacrificed ten to the power of billions of living beings and received one divine-grade summon!"

Chen Feng: "I think I've opened the door to a whole new world."
