Japan's invasion of China extended its claws to the grasslands, leading to a situation where the common people struggled to survive. This situation even stirred a sense of nationalism in Wurigen, who originally came from a bandit background. Wurigen had feelings for Narenhua, but she ended up marrying Tauk. When Wurigen waited for trouble, he startled the Japanese horsemen, and in a fit of rage, Oda killed Narenhua's brother and father. Wurigen and the others shot to draw the Japanese away. The Japanese searched everywhere for the horses and clashed with Tauk, who, in anger, dragged Oda to death with his horse. Captain Zhu Tian and others hunted him down, and Tauk fled with Narenhua but encountered Wurigen on the way. Despite having had disputes with Tauk, Wurigen's sense of nationalism led him to save Tauk. Wurigen's group intended to frame Tauk, but in the end, they did not go through with it. His conscience reminded him that a real Mongolian man should not attack a drunk person. Tauk invited Wurigen to fight the Japanese together, but he was refused. The Japanese also tried to bribe Wurigen but were mocked instead. In anger, they stole Wurigen's horse, and Tauk extended a helping hand, which moved Wurigen. He finally united with Tauk and Honggeer to fight and annihilate the Japanese troops. Unfortunately, Wurigen was shot while trying to save Honggeer and died. As everyone was still in mourning, a large number of Japanese soldiers entered the grasslands again, and Tauk finally decided to venture into the inland to find the 'Red Army' to drive the Japanese out of the grasslands.
