Signing Into the Cold Palace for Eighty Years, I Am Unbeatable in the World

After transmigrating into the crown prince of the Yuhua Divine Dynasty, Lin Jiufeng is stripped of his prince status and exiled to the cold palace because he let go of a saintess from an enemy nation, and is forbidden to leave.

Lin Jiufeng is not very saddened. He came with a sign-in system: as long as he signs in at different locations, he will receive rewards.

At the gate of the cold palace, he signs in and obtains the Heaven-Splitting Sword Drawing Art!

In the imperial council hall, he signs in and obtains the Heaven-Mending Art!

In the empress dowager’s palace, he signs in and obtains the God of War Diagram!

...

Lin Jiufeng thought he would keep signing in quietly until he became invincible under heaven, but who would have thought that after the heavenly concubine he secretly released returned to her homeland, she raised troops in rebellion and seized power.

After taking power, the first thing she does is attack the Yuhua Divine Dynasty to rescue Lin Jiufeng.

After hearing this, Lin Jiufeng is completely baffled: "I need you to rescue me?"
