[2][3] In the late-Yuan dynasty of China, martial art sects and warriors fight for the lost Dragon Sabre which, according to legend, grants its possessor rulership of the world.

Xie Xun arrives there the next day and the three of them decide to become a family disregarding their differences due to the birth of Cuishan and Susu's child, Zhang Wuji.

Cuishan takes responsibility for the many murders Susu committed in the past and suicides in front of multiple sects to protect his new family.

Yang Xiao asks Xiaofu to take care of an orphan girl named Yan'er who has endured abuse for one month.

Later, Miejue kills Xiaofu in grief with her palm strike for choosing Yang Xiao over Emei and this is witnessed by Wuji and Buhui.

Before Xiaofu died, she asked Wuji to send Buhui to her father Yang Xiao, and then returns to Wudang.

Wuji crawls through a narrow tunnel and finds the Nine Yang Divine manual from a white ape and masters it.

Zhu'er and Wuji escape but Emei's disciples take them prisoners on their way to Bright Light Peak to exterminate Ming Cult.

Wuji receives three powerful punches from Miejue to save the lives and limbs of Ming Cult's Five-Colored Flags residents.

Wuji unintentionally masters the Ming Cult's most powerful martial art of Heaven and Earth Great Shift and saves the cult from extermination by the Great Six sects, nearly losing his life in the Bright Light Peak battle but not until revealing his true identity to his family who is the opposing sects by his deceased parents.

On the way, they come across Wuji's sixth uncle, Yin Liting, whose joints are broken by Shao Lin's people, who turned out to be Zhao Min's subordinates.

Prior to the attack on Wudang, Zhao Min had already successfully captured and kept the Great Six sects in Wan An Si.

A Ming Cult member and a spy within Zhao Min's people, Fan Yao, saves the sects.

One morning, Wuji wakes to find Zhu'er dead and that Zhao Min, the Heavenly Sword, and the Dragon Saber are missing.

Zhiruo gives the Book of Wumu to Wuji, who wins a few battles, but the tide turns after Zhao Min is killed by her father.

Many people die, including Qingshu, Minjun, Yin Tianzheng, Xie Xun, many different cult disciples, and many Mongolian soldiers.

Zhao Min leaves Zhang Wuji when he chooses his country over her but says he still cares for her and vows to go to Mongolia and find her.

Wuji, wanting to end China's thousand years dynastic rule to give people the opportunity to govern the country, chooses to relinquish his chance to be sovereign and charges his followers to carry on protecting China against tyranny, injustice, and other threats.

Off-screen, Zhu Yuanzhang, having earned a heroic reputation that rivals Wuji's from his battles against the Yuan forces, declaring that China needs a leader and wins support from his subordinates and allies, and becomes the Ming dynasty's founder, the Hongwu Emperor, foiling Wuji's plan for China's self-governance.
