Exposed as the counterfeit heir from the very beginning, I ascended to the throne as emperor on the spot

In the 170th year of Yong’an during the Great Wei Dynasty, a clandestine scandal involving a royal mansion shook both the imperial court and the immortal sects.

The infamous only son of the Prince of Zhenbei, widely known as a worthless, rotten-to-the-core scoundrel, was revealed to be the son of a lowly horse slave secretly swapped into the family by the former Demon Sect years ago.

The true heir, it turned out, was the newly crowned top scholar—a direct disciple of the Sage himself, bestowed with a breath of "Haoran Righteous Qi".

Instantly, the entire Great Wei erupted in jubilation, celebrating the royal mansion’s restoration of its rightful lineage and the recovery of its “auspicious heir.”

...

“This is all very joyous indeed. It’d be even better if this ‘fake heir’ weren’t me.”

Gu Fangchen faced the Prince of Zhenbei and the true heir, who had come to confront him, while glancing at the randomly generated profession above his head:

[Emperor (1 Day)]

[Skill 1: Mandate of Heaven (Passive)]

[Skill 2: Life and Death Decree (Active)]

Back then, the Princess Consort of Zhenbei was still tender as water, doting on her son to the point of obsession.

The eldest princess was icy and aloof, her smile rarer than a thousand pieces of gold.

The youngest princess was naively charming, obsessed with heroic tales and loathing all unscrupulous villains.

The elder princess commanded armies like a god of war, while the female State Preceptor overturned storms with a flick of her hand.

The moment Gu Fangchen opened his eyes, he knew: he’d crossed into this world to become emperor.

"Those who obey shall prosper; those who defy shall perish. All of you—show some respect!"
