The leader of the country, Sima Haotian, is kind to the people and loves things, and is deeply loved by the people. A few years later, Longzi was named Yulong. When Yulong was 8 years old, Prime Minister Ye Hong colluded with foreign countries to seek power and usurp the throne, and the country's leader suffered an accident. In order to protect his young master, the good general Zhao Yi exchanged the clothes of his son Zhao Yu and Yulong, and stabbed Zhao Yu off the cliff in front of the enemy, pretending to surrender to the enemy, waiting for his return to the country. In order to protect the Jade Dragon, the queen also fell off the cliff, her life and death unknown. Fortunately, Zhao Yu and Yulong were saved by the eminent monk Kongkong and their lives were saved. Ten years later, Yulong and Zhao Yu grew up and shouldered the responsibility of restoring the country. They went down the mountain to find Zhao Yi. Zhao Yi arranged for them to stay in the city and just waited for the opportunity to restore the country.
