Antique dealer Chen Feng traveled through the Tang Dynasty and became the prince Li Ke with the blood of the former Sui Dynasty. He was trapped in the whirlpool of imperial power and identity crisis. In a desperate situation, he activated the 100,000-square-meter static space jade pendant he carried with him, which can store items and plant crops. In order to survive and be free, Li Ke made a strategy of "obscene development": taking advantage of the situation, Prince Li Chengqian and Emperor Li Shimin became apprentices to Qin Qiong and Li Jing, and secretly hoarded wealth, technology, and talents. He offered up plans for disaster relief and cleverly gave up the credit; he founded the "Qionglou Yuyu" business empire and gathered huge sums of money; he even secretly built the future navy based on Shu. When the prosperous age of the Tang Dynasty was rising, Li Ke had set his sights overseas. In the fifteenth year of Zhenguan, he personally led the fleet to conquer the Japanese country in the east, destroyed it, and incorporated it into the territory of the Tang Dynasty, setting it as the "East China Sea Protectorate". He moved the people to assimilate, burned history and changed customs, and finally became a free king over thousands of miles of sea. With the jade pendant in my arms, the space is still the same, and I am free and easy, and I am on my way home.
