Ye Fan, a former king-level beastmaster, is reborn into his youth. Initially assessed with a D-grade beastmaster talent, he's only allowed to have a fire dog with inferior bloodline. Having spent years at the peak of beastmastering and knowing the evolutionary paths of various beasts, he now contemplates whether to evolve his fire dog into a Flame Qilin or an Undead Wolf. This is an era where beastmasters rule and everyone has a beast. Ye Fan starts over, determined to leave no regrets. This time, he will destroy his enemies, eliminate the wicked, and reclaim all that he has lost! Ultimately, he will lead his beast army, explore various secret realms, sweep across the Dark Forest, level the Netherworld, and conquer the Sky City!
