My Whole Family Is to Be Executed? I'll Cling to the Tyrannical Crown Prince

Pei Zheng, an overworked history graduate, died suddenly and became the most notorious wastrel in the capital of the Great Yuan.

From the start, he was on hell difficulty: the woman he'd called Mother for twenty years was actually a wicked concubine who had switched babies at birth; his real mother was imprisoned and poisoned; and the sweet, innocent fiancée he'd tried so hard to please was a deadly spy sent by the Third Prince!

In this desperate situation, Pei Zheng awakened the [Regent's Aid System] and was forced to bond with the disabled, vicious-tempered crown prince. If the crown prince died, so would he!

To survive and take revenge, Pei Zheng cast aside his mask and went on the offensive!

On the inside, he used modern medicine to heal the crown prince's legs and soothe his twisted temperament. On the outside, he introduced soap, glass, and gunpowder, using advanced technology to overwhelm his enemies.

The fake young master wants to steal my rightful title? I'll strip him of everything and grind his bones to dust!

The Third Prince wants to seize the throne and rebel? I'll point a cannon at his face and send his whole family sky-high!

When Pei Zheng returned to court with the crown prince, now healed, the entire court dropped to its knees.

Years later, Emperor Yuan gazed at the mountains of gold and silver filling the treasury and the invincible rifle corps sweeping across the land, lost in thought. “So which of us is the emperor, you or me?”

Pei Zheng smiled faintly. “I am merely the Great Yuan's foremost party leader and the crown prince's personal companion.”
