Spirit Beast Evolution

He was reborn in a different world where demons had invaded and killed 80% of humanity. Humanity had a chance to survive when some survivors began to awaken the power to control Demonic Beasts, the Beastmasters.
Although originating from a poor background, the original owner of his body aimed to become a top-tier Beastmaster. Unfortunately, he experiences bullying at school due to making a spiritual contract with an alpaca rather than a more powerful beast.
He vowed with a glimmer of resolve not to be bullied, but the alpaca in front of his eyes threw his plans into disarray. Regardless, the timely arrival of his golden finger, "the System," turned everything around.
With the system, he discovered that even his laziness could lead to his alpaca's evolution! Within a short time, his alpaca changes temperament radically and evolves quickly.
Now armed with cheats, Han Feng begins his journey to become a top-tier Beastmaster and protect humanity from the demons that threaten their existence. It is simply the beginning of the era that belongs to him.
