[Swordsmanship, ruthless killing, conquering the world, invincible protagonist, multiple female leads but not brainless]

Ten years ago, the demon queen of Yu the Great failed in her attempt to overthrow the court, and her blood was spilled in the imperial city. She left behind only a mad and incompetent child who could not cultivate, who was demoted to a commoner and became the greatest disgrace to the royal family.

Ten years later, a mad boy returns with "The Tomb of the Sword Immortal Emperor"; his name is Jiang Chen...

They call him a madman, for he could slay gods and men with a mere flick of his finger.

He may be called a fool, but one of his wild poems made even the most sage scholars bow down in admiration.

Despite being called a useless man, he single-handedly conquered the country, dominating five kingdoms and ten dynasties, with no one daring to raise their head.

He was said to be extremely cruel, yet he was surrounded by women of unparalleled beauty...

He may be called cold-blooded and ruthless, but he opened the gates of heaven with a single sword, saving the common people from suffering...

Others laugh at my madness, but I laugh at their ignorance...

"Sword, come!"

"In this life, wherever the sword points, that is the path to kingship!"

[Time travel + alternate history + prince consort + no system + showing off and face-slapping + multiple female leads]

Yang Yi's soul transmigrated, becoming the only grandson of the Duke of Zhenguo of the Great Wei Dynasty.

The most notorious playboy in the Great Wei Dynasty, with his noble status, wealth, and power, should have had an incredibly enjoyable life.

Before he could even laugh out loud, he learned that the emperor had bestowed upon him a marriage, to be with the legendary, arrogant, and venomous Princess Anning.

Yang Yi's pupils dilated in shock: "Marry a princess? You have to bow and kneel on a washboard every day, and you can't even take concubines? Do you want this kind of blessing?"

In order to escape this "tragic marriage," he embarked on a path of self-destruction.

Brothel brawl, harassing the courtesan, beating up the princess...

But who could have imagined that the more he acted, the brighter the Emperor's eyes became on the dragon throne: "This kid is shameless! Arrogant! He has the style of my youth. I like him, so he's the one."

Even more outrageous, Princess Changning, who was rumored to be as elegant as bamboo, got involved, saying with a smile, "If my sister doesn't want it, then I will."

Yang Yi: "...Wait, this script isn't right?!"

Thus, a grand "battle against marriage" was transformed into a headline story in Chang'an: "Two princesses vying for the prince consort."

Meanwhile, Yang Yi, forced by the emperor to "shoulder the responsibility of two princesses," secretly pulled out gunpowder formulas, economic strategies, and modern military tactics...

"Since there's no escaping it, then don't blame me—I'll lie drunk on a beauty's lap and wake up to wield power over the world!"

If you don't cause trouble during a time travel, is it even a time travel story?
