Great Tang: My Sons Are a Few Hundred Million Too Many

Transmigrating to the end of the Sui dynasty, he becomes a teenage Li Shimin?

He'd been planning to make a big splash using his modern sensibilities. After all, he was a modern man. But who could have guessed that the System he'd awakened would be so strange?

"Ding! Conceal your transmigrator identity for one year. Reward: master-level calligraphy."

"Ding! Conceal your transmigrator identity for five years. Reward: The Yellow Emperor's Inner Canon and master-level bedroom arts."

He conceals his identity and follows the course of history, yet suddenly realizes that several of his sons are a little strange.

And the person he met while out on a trip turns out to be a hidden genius, too?

What is going on? Don't tell me I'm going to end up with a few posthumous children by the time this is all over.
