Ten Years in the Eastern Palace, and the Fake Crown Prince Is a Woman

Jiang Yuan, of the Great Yuan Dynasty, is assigned to the Eastern Palace as a lowly night watch guard.

The succession struggle is reaching its peak, and the whole court insists that the Eastern Palace is doomed. Jiang Yuan is seen as expendable, likely to lose his head at any moment.

Then one night, he accidentally stumbles upon a world-shaking secret:

The usually aloof and dignified Crown Prince is actually a woman!

Fortunately, the Great Dao Sign-In System awakens.

"Sign in at the Eastern Palace armory. Reward: Great Luo Sword Embryo!"

"Sign in at the Crown Prince's bath. Reward: Divine Elephant Suppressing Prison Strength!"

Following the principle of not leaving seclusion until he is invincible, Jiang Yuan quietly signs in for ten years, watching the court's fortunes rise and fall.

Then one day, powerful ministers rebel, an army of one hundred thousand bears down on the city, and the Eastern Palace is on the brink of destruction.

The false Crown Prince, Chu Youwei, is filled with despair. She prepares to take her own life to protect the secret of her sex and preserve her last shred of dignity.

Just then, a sword rings out across the Nine Provinces!

Jiang Yuan rises into the air. His sword shines coldly across nineteen provinces, slaying gods and Buddhas in the heavens and wiping out the one hundred thousand rebels!

After crushing everyone in his path, Jiang Yuan looks at the dumbstruck Chu Youwei and smiles. "Your Highness, your dragon robe is torn. Time to change into women's clothes."

Chu Youwei is shocked and embarrassed. "My ruined Eastern Palace was hiding an immortal who transmigrated here? Wait, how did he know I'm a woman?!"
