Great Tang: At Four Years Old, I Smash Walnuts with the Imperial Seal

Li Zhi is reborn as a four-year-old prince of the Tang Dynasty and binds himself to the Brat System, receiving the Imperial Jade Seal. To complete the "smash walnuts" mission, he uses the seal to crack walnuts, making Li Shimin furious. Armed with his slender-gold calligraphy and quick wits, he survives by being "mischievous" in the palace and sets out on a hilarious path to becoming emperor.
