Lin Yuan was originally a genius on the side of the Great Xia royal family, but he was prophesied by the "Body Abandoned by Heaven". His Dantian was destroyed and his meridians were severed. He entered the palace of the Duke of Zhenzhen and became a humiliated son-in-law. His wife Su Waner handed him a letter of divorce, and he was bullied by the housekeeper's son Wang Chen. When he was about to die, he activated the Eternal War Soul Sign-in System and obtained the "Immortal Divine Body (Fragment)" and the essence of the Overlord War Soul, reshaping his body and regaining his strength.
In order to take revenge, Lin Yuan signed up for the Royal Martial Arts Examination. With the help of the "Great Sun Vajra Technique" and "Shadowless Step" unlocked by signing in the system, he crushed his opponents along the way, defeated strong men such as Li Jinghong and Zhao Lie, and shocked everyone. During this period, he encountered an assassin sent by Wang Teng, the deputy commander of the Military and Horse Division (a participant in the Zhenbei Palace massacre). After killing him, he found out the grudge relationship.
In the final, Lin Yuan faced off against Wang Teng with the Spear of Remnant Soul and won with one shot. From Wang Teng's memory fragments, he learned that the "Body Abandoned by Heaven" was a man-made seal, the jade pendant left by his parents was the mysterious key, and there was another mastermind behind the scenes. In the end, Lin Yuan killed his direct enemy, determined to track down the real culprit behind the scenes and avenge the 317 dead souls of his family.
