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.
