My Tomboy Friend Turned into a Succubus, and I Got Lucky!

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

When he turned eighteen, awakened his profession as a Dark Summoner, and performed his first summon, he never expected...

To summon that very friend to his side. Two years earlier, she had awakened ahead of schedule and been admitted to a prestigious academy.

"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 me this little favor, right?"

"There, be good and listen. Leave everything to me."

After that, Chen Feng developed a fondness for lamb kidneys.

Just when all hope seemed lost, he was lucky enough to awaken a System.

But...

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

"Sacrifice billions of living beings to gain one Golden Summoning opportunity."

"Sacrifice billions of beings squared to gain one God-Tier Summoning opportunity!"

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