He died. Not by fate, not by accident, but as collateral in a hunt between beings beyond mortal comprehension.And yet… death was only the beginning.Chosen by a mysterious entity known only as Echo, a sarcastic soul from Earth is offered a chance at a second life. Gifted with ten draws from a divine treasury, he obtains powerful treasures, a rare bloodline, and a mysterious system known as the Limitless System.But what begins as a straightforward reincarnation takes a twisted turn when two dragon inheritances—Thunder and Fire—collide within him.Reborn not as a man, nor as a beast, but as an unknown species—a fusion of human and two True Dragon Inheritences—he awakens in a scorched battlefield beside a dragon egg, unaware that his birth was witnessed by fate itself.After surviving the near-fatal clash of legacies within him, he emerges anew… no longer Zaroth, but Primus Xal’Zaryon Drakonis, a name that shakes the very fabric of mana around him.With his soul, body, and bloodline perfectly harmonized between human and dragon, Primus sets out into an unfamiliar world ruled by ancient clans, dangerous beasts, and kingdoms teetering on the edge of Eternal War.But power always draws attention—and with the secrets of his origin, the Limitless System at his side, and a destiny marked by a Primordial-level Mark of Fate, enemies will rise from shadows unknown.

Jacob Steve, an Old Man, died at 116 after living a whole life.

But Jacob always had a dark side, which he always suppressed and hid from others.
However, in the later years of his life, when death was inevitable, he understood there wasn't any point in having wealth, knowledge, or desires if you couldn't have a life to enjoy them.

He became obsessed with fabled immortality and devoted his reaming life to extending his fleeting lifespan, but just like any other failed.

However, he mysteriously got another chance at life and found a way that led to fabled immortality.
But he was also forewarned that the way led to it was filled with blood and darkness!

In the end, Jacob chose it anyway with no way of going back, and it was also the start of his suffering and his icky, brutal journey toward the 'Immortality' he wanted so badly!

The “Dog Emperor” gets adopted by his fake “Favored Consort.” This story follows their story as they experiences all sorts of trials in the imperial harem and find true love.

The dog king will recover his human body.

This is not a legitimate harem drama novel – there will be love, there will be pampering.

Enormous silver platters, shocking melodramas, all part of the package.

Looking at his own concubines and imperial offspring from a doggy’s perspective:

Who used to be the sweet and gentle eloquent flower turns out to be a venus fly trap behind the scenes.

Who used to be the filial and courteous, intelligent and adorable imperial princes and princesses transform into demons in a flash.

The progression (of the story) overturns understandings and unmask countless illusions.

But by the protection of the gods, the dog emperor met a healing owner. Although the path is rough, the end is pleasant.
