Three Years of Sign-In at the Heavenly Prison, Then I Emerged a Mortal Immortal

After transmigrating to another world, Zhao Zheng becomes the crown prince regent of the Tianyu Dynasty.

His father, the emperor, enters seclusion for ten years to master an ancestral secret art and oppose the Imperial Preceptor.

He appoints Zhao Zheng to govern the country as regent.

But wary that Zhao Zheng might rebel and seize the throne, he has him thrown into the Heavenly Prison in the seventh year.

Fortunately, Zhao Zheng activates the sign-in System and rises against all odds.

[Congratulations! Sign in before the Heavenly Prison's Grand Ancestor statue to receive the Supreme True Dragon Body.]

[Congratulations! Sign-in successful in the Heavenly Prison corridor. Reward: Dragon-Elephant Embryonic Bone Pill.]

[Congratulations! Sign-in successful on the second level of the Heavenly Prison. Reward: True Dragon Emperor's Sword.]

Three years later, Emperor Shiyuan emerges from seclusion, intending to execute the crown prince, wipe out the Imperial Preceptor, sweep across the immortal sects, and reclaim the throne.

But he discovers that Crown Prince Zhao Zheng has already become emperor, commanding a million elite troops and thousands of renowned generals.

“Father, are you planning to rebel?”
