- Description from novelbuddy

I, Hyoudou Issei, am a 2nd Year High school student and my age is equal to the number of years I haven’t had a girlfriend. And, someone like me got a girlfriend! I’m sorry buddies, I will walk the path of becoming an adult before you guys! – That’s how it was supposed to be, but why did I get killed by my girlfriend!? I still haven’t done anything yet! Are there no Gods in this World!? And, the person who saved me is the most beautiful girl in my school, Rias Gremory-senpai. I learned the shocking truth from her who isn’t a God but a Devil. “You have reincarnated as a Devil! Work for me!” Lured by Senpai’s breasts and treats, my life as a reincarnated Devil began. So the “Academy×Love Comedy×Battle Fantasy” starts here with just aggressive and worldly desires!

After being transmigrated to the world of the game Global Lord, Wang Xiao received a beast as his beginner unit.

His start was a little lackluster, but, fortunately, he had also received the 10000x Amplifier system.

The beginner bloodline was amplified by 10000 times.

His F-grade beast, Black-furred Dog, immediately became the S-grade beast, Cerberus.

The time was sped up by 10000 times.

The 30 years that it would take the A-grade beast, Immortal Pheonix, to mature had been shortened to one day.

The reproduction rate had been increased by 10000 times.

In just over a night, the SSS-grade beast, Primordial Divine Dragon, had bred a ton of baby dragons.

Every other lord was stunned.

“Why are his beasts growing so fast?”

“Are you telling me that huge island is actually his Divine Beast, the Black Turtle?”

“10000 Ancient Titans from the east and 10000 Mammoths from the west? How am I supposed to fight that? I’d rather just die!”
