[Great Tang]+ [System]+ [Wish-Fulfillment]+ [Unhinged]+ [Lighthearted Comedy]
After transmigrating to the Great Tang, Li Chengqian becomes the crown prince. Just then, Li Shimin grants Wude Hall to Li Tai.
As Li Chengqian wonders how to deal with Li Tai, he suddenly obtains a System. As long as he defies an imperial decree, he can draw martial arts, medical skills, calligraphy, and even bizarre techniques.
From then on, Li Chengqian sets out to beat up Li Tai, talk back to Li Shimin, and defy imperial decrees without end.
Wherever there's an imperial edict, there you'll find Li Chengqian.
As soon as Li Chengqian shows up, he defies it.
Several years later.
Li Shimin discovers that every one of the hundreds of imperial edicts he issued has been defied by Li Chengqian.
Yet the Great Tang hasn't fallen apart. In fact, it has grown stronger than ever.
Li Shimin: Crown Prince! Please stop defying my edicts. I'll abdicate right now!
Li Tai: Big brother, there were a lot of people around just now. I was wrong before. I'll get down on my knees and beg you.
The aristocratic clans: Crown Prince, please show mercy and stop taking everything from us!
The foreign tribes: Our people are willing to honor the Crown Prince as the Heavenly Khan!
The civil and military officials: Your Majesty, please abdicate and let the Crown Prince ascend the throne!
Too much nonsense, too old routines, and a lot of useless language. You need to skip reading.
