Shangguan Yan

Shangguan Yan was a successor of the Heavenly Whale Dominating Fist and a major ally during Xie Yan's mission to Ba Quan. She and her younger sister, Shangguan Yao, are currently merged with the Evil God, Ava.

Personality and Traits
Shangguan Yan is a reserved and polite girl, in contrast to her mischievous and bubbly sister. Although she often bickers with Shangguan Yao, both sisters care for each other. Shangguan Yan has immense admiration for Xie Yan because of his superior strength and generosity. Likewise, Xie Yan is caring and protective towards the sisters. After being corrupted by the Evil God, the girls exhibit a dark romantic obsession with Xie Yan.

Plot
The Shangguan sisters had inherited the Heavenly Whale Dominating Fist from their father, Shangguan Xiongba, before he passed away, due to the fighting art shortening his life. Eventually, Shangguan Yan ignited her will and became a C Class Fighter. While training on a deserted island, she is suddenly attacked by Cross, a B Class Fighter and hitman. Cross defeats Shangguan Yan, but before he can kill her, she is saved by Xie Yan, who had recently teleported to Ba Quan. The system issues a mission to Xie Yan, commanding him to safely escort Shangguan Yan to her home, and join her family. Moments later, Xie Yan kills Cross and heals Shangguan Yan. He introduces himself as the last Sword Immortal from the Sword Immortal Sect, and is unfamiliar with the outside world. Shangguan Yan invites Xie Yan to her home in Lin Hai city, where he meets Shangguan Yao. Xie Yan learns about the powerful fighting arts of this world as well as the Fallen Fighters. Later, the trio discover that Cross was hired by the rival Fujita family, who run the Niten Isshin-Ryū school. The next day, when the sisters confront the Fujita family to conclusively settle their dispute, the grandmaster Takeshi Fujita mutates into a Fallen Fighter. Amidst the chaos, Xie Yan rescues the sisters and kills Takeshi Fujita. The girls profusely thank Xie Yan for saving their lives and the system declares his first mission to be complete.

The next day, Xie Yan learns the basics of the Heavenly Whale Dominating Fist within three hours. He learns that the Heavenly Whale Dominating Fist, the Blue Dragon Dominating Fist, and the Gentle Fist Of Nirvana are the three fragments of the extinct Everlasting Dominating Fist, the ultimate fighting art which was created by Zhu Ji. The only way to obtain the other two fighting arts is to request the respective successors during the 11th Global Fighting Summit, a decennial tournament which will commence in two months. The system promptly issues a second mission to Xie Yan, ordering him to team up with the sisters and win the Global Fighting Summit. Xie Yan decides to use his Divine Impact Of Zen to pose as a Fighter.

Two months later, the trio travel to the Summit venue, where they undertake tests to evaluate their Fighting class. Shangguan Yao is categorized a C Class Fighter while Shangguan Yan is categorized a B Class Fighter. Xie Yan shatters the testing machine and is categorized an S Class Fighter, making him the captain of the Heavenly Whale Team. The tournament prize is revealed to be the Universal Secret Pill- a crucial component to revive the Everlasting Dominating Fist. The next day, the Summit commences, and the Heavenly Whale Team wins the first bout for the day. That evening, Xie Yan becomes acquainted with fellow participant Meng Zhang, the chairman of the Shenwu Association. He learns of Meng Zhang's mission, as well as the information of the seed of the Evil God. The next evening, Xie Yan acquires the seed and stores it. Over the next few days, thanks to Xie Yan's stellar performance, the Heavenly Whale Team makes it to the Finals. Xie Yan learns the Gentle Fist Of Nirvana and the Blue Dragon Dominating Fist from their respective successors, Ge Hong and Chi Lian. He obtains the basics of the Everlasting Dominating Fist after fusing the three arts. On the day of the Finals, Xie Yan confronts the Shenwu Association, but strangely, Meng Zhang forfeits the match and the Heavenly Whale Team members become the champions of the Summit. Xie Yan completes his second mission and consumes the Universal Secret Pill.

Suddenly, the skies turn gloomy. It is revealed that the Fighting Summits were actually a century long resurrection ceremony for the first Fallen Fighter, Qiu Sheng, who appears at the arena and begins to summon the Evil God, Ava. The system orders Xie Yan to prevent the descent of the Evil God. The Shenwu Team and Chi Lian use the Power Of Gaia to trap Qiu Sheng, but the latter overcomes this by absorbing the Power Of The Evil God from the Shangguan sisters. The heroes teleport themselves and the Fallen Fighter to an isolated space, where they fight to the death. Meanwhile, Xie Yan ignites his will, and with the help of the Power Of Gaia and Zhu Ji's spirit, he successfully masters the Everlasting Dominating Fist. Upon learning that the heroes have been defeated, Xie Yan enters the isolated space using a fragment of Gaia, and after an extremely arduous battle, he kills Qiu Sheng. Unfortunately, this does not stop the Evil God's descent, and for the first time, Xie Yan fails his quest.

The Evil God devours all life on the planet as well as the Power Of Gaia, leaving Xie Yan as the last living being on the planet. The entity approaches the horrified Xie Yan, merging with the Shangguan sisters. Ava offers to create an alternate reality where everyone will live with different memories and where Xie Yan can reign as the supreme being. Xie Yan realizes that the Shangguan sisters are the incarnations of the Evil God, and even if he did succeed the third quest, it would only delay the apocalypse by fifty years. He is nearly corrupted by the Evil God, all his origin points are depleted, and his system is almost destroyed. At the last moment, Xie Yan recovers and teleports to the main world. Ava angrily vows to eventually invade the main world and reclaim Xie Yan.

Trivia

 * The world of Ba Quan contains elements from previous minor worlds:
 * Xie Yan protects his family from enemy swordsmen like he did in Yun Shan.
 * He learns hand to hand combat and uses defensive skills to win a tournament like he did in Qian Ming.
 * He encounters the Power Of The Evil God, which is similar to the Demonic Cultivation Sword he saw in Qun Xiong.
 * He faces a supernatural being like he did in Tong Ling.
 * He faces an antagonist that feeds on negative emotions like he did in Zhan Shen.


 * After winning the 11th Global Fighting Summit, the Heavenly Whale Team receive the following prizes:
 * One Universal Secret Pill.
 * Three Black Diamond Credit Cards each worth 100 million yuan (~15 million USD).
 * A private island in Japan.
 * As the incarnations of the Evil God Ava, the Shangguan sisters remained ignorant of their true nature. It was only after Xie Yan gave them the Transcendental Spirit Nurturing Technique that they were able to retain their consciousness when merging with the Evil God, granting sentience to the deity. Xie Yan regretted this action since he just wanted to improve the lifespan of his friends.
