Book 1 of the Codex System Series.
*****
In the fantasy world of Terra, people are divided into two kinds: Those who have mana and those who don’t. The registered mana users are called hunters, and the ones without the mana are called plainfolk. Lin Fang, unfortunately, has been the latter since birth. 

But his misfortune didn’t end there.

After his father’s sudden demise, his mother remarried, leaving him and his sister in the hands of his grandmother. But later, his grandmother also passed away, and his sister moved abroad, leaving him all alone at just 16.

All he had left was a struggling pet shop and his late father's unfulfilled dream of making it thrive.

Fifteen years later, Lin Fang is drowning in debt, betrayed by his unfaithful wife, and addicted to alcohol. His life has hit rock bottom. Filled with many regrets, he jumped into the river to escape this suffering.

But when he did, he neither died nor ended up in the hospital.

Instead, he found himself regressing 7 years into the past, with a mysterious Prehistoric system activated by a pendant he had carried since birth.

Now, with the power to command monsters and carrying the knowledge of the future, Lin Fang set out to redo his life, whether it is becoming the strongest tamer to control prehistoric monsters, getting his true love he had walked away from before, or becoming the richest businessman.

As the bear's size towered over him with its eyes burning with killing intent, Alpha's voice echoed in Lin Fang's mind. "Lin Fang, proceed as if you were facing a Lord Tier Beast."


Lin Fang's jaw tightened. "A Lord tier, huh? Maybe I shouldn't have deactivated the skill earlier."


With a flick of his wrist, twin daggers of Xuanwu materialized in his hands, and he exhaled once, lowering his stance. "Alright then," he muttered. "Let's end this quickly."


The bear lunged forward, swiping the claws like cleavers through the air. Lin Fang dodged sideways, evading the attack by a hair's breadth, and then he countered with a downward slash. The dagger cut deep across the creature's forearm, spilling blood to the floor.


The beast roared and swung again, this time faster. Lin Fang met the blow head-on once again, crossing both daggers to parry. The impact sent a shockwave that shattered nearby glass panels, blasting Lin Fang to the back.
