In the main hall square of Wudang Mountain, people from various factions besieged Zhang Cuishan's family due to old affairs. When Zhang Cuishan was in danger, he asked for help from his uncle Dong Tianbao, who had been reclusive for many years. Dong Tianbao has a handsome appearance, but he is actually a martial arts master who has lived in Wudang for hundreds of years. He gently resolves disputes with his profound martial arts and inspires everyone to let go of their obsession with the world. When Dong Tianbao saw that Zhang Wuji was suffering from cold poison, he took action to heal his injuries. He also taught orthodox martial arts techniques and guided everyone to abandon private fights and care about the common people. He does not value fame and fortune, but is committed to protecting his relatives, friends and people with the right path. He is also determined to protect the stability of the world with the power of martial arts and cares about the people of the world.
