Every shadow in this ancient realm is a potential grave, an ominous echo of treacherous alliances and age-old powers.

Tang Lei, the genius of the East Emperor Realm, had refined a Sixth Grade Pill at the age of 95 and became the youngest Pill King in the history of the East Emperor Realm.

However, all of this came to an abrupt end when Tang Lei explored an ancient ruin and obtained the inheritance of the ancient overlord.

The East Crown Prince, Dongfang Mingsheng, revealed his wolf-like nature and attacked Tang Lei to forcefully seize the inheritance. After a fierce battle, Tang Lei was unable to hold on and died.

Yet, the tale refuses to succumb to an early end. Beyond the knowledge of this world, a scant fragment of the deceased man's soul eluded its grim fate, slipping into oblivion to seek sanctuary.

Ironically, this elusive soul found a fresh vessel in a man sharing its former name!

The surprise didn't end there. As the soul nestled into its newfound host, it discovered an astounding reality—the martial soul inhabiting this new dantian surpassed the might of its previous one!

"What sort of Martial Soul is this?" The young man questioned, gazing at the new Martial Soul flickering with a soft golden hue in his dantian.

"My Pill Fire Martial Soul has been eradicated; why has a fresh, far more powerful Martial Soul taken its place? This strength surpasses even a Heaven Rank Martial Soul. Could it be... a Saint Rank Martial Soul?"

Now, reborn with a formidable martial soul and a voracious thirst for revenge, the man with a second chance pledged to confront the East Crown Prince and his nefarious allies. But, is he capable of harnessing both alchemy and martial arts, scaling the apex of power, and seizing the elusive title of the dual emperor?

As Tang Lei commences this perilous quest for justice and supremacy, the question remains: Will he succeed in his pursuit or be ensnared in the unforgiving machinations of gods and demons?
