When he woke up, Lu Qingdu, a modern Chinese medicine doctor, turned out to be the cannon fodder in "The Legend of the Condor Heroes" who got a box lunch as soon as he appeared - Lu Qingdu, the fat man from the Quanzhen religion.
At the end of the Southern Song Dynasty, the imperial court was experiencing internal and external troubles, and undercurrents were surging in the world. He knew full well that his honest body would soon be resented for making things difficult for Yang Guo, and would end miserably. It is even more heartbreaking because of the regret that Yang Guo and Guo Fu had been misunderstood for half their lives in the original work, and the catastrophe that more than ten years later the mountains and rivers were shattered and the land of China was destroyed.
Now that he knows his destiny, he wants to change his destiny. A young disciple of the fourth generation, he has been hiding his clumsiness and forbearance ever since. He practiced Quanzhen Xuan Gong diligently, studied medical divination strategies, and quietly changed everything with his insights and calm mind that transcended the times.
When Yang Guo went up the mountain, he stood up to protect him, confessed his past, and guided him to the right path. He also made clever arrangements in the rivers and lakes to save Lu Wushuang, seek adventures, and form good relationships.
He is not only willing to complete the difficult meaning in the book, but also to save the world. Secretly cultivate the future Optimus Prime, assist the prince in forming a new army, and innovate weapons. Finally, at the top of the city of Xiangyang, he defeated the destiny of the Condor Heroes side by side; he launched the Northern Expedition, regained the Central Plains, and personally washed away the centuries-old national humiliation.
From a "little fat deer" who can be bullied by everyone, he is poor but takes care of himself, and slowly grows up to become an expert and help the world. He uses Chinese medicine to diagnose the pulse of the Song Dynasty, and then assists the new emperor and lays the foundation for the resurgence of China. With his heart to save the world, he saved the Song Dynasty, which not only fulfilled his dream of rivers and lakes, but also reversed the fate of the country. This is a story about protection, compensation and reinvention.
