Yun Jinghan, who was once the best cultivator in the world in "Mysterious Realm", was betrayed by his Taoist companion Su Qingyao and his junior brother Chu Zhao, and died tragically at the mouth of the Shadow Candle Dragon, the BOSS of the Immortal Realm. However, he was unexpectedly reborn and returned to the story 72 hours before the launch of the game.
After resurrecting his life, he gave up magic and turned to swordsmanship. He relied on his past life memories to seize hidden opportunities such as the "Innate Sword Bones" and quickly rose to prominence with his fierce swordsmanship. Faced with the oppression of Tianyan Sect and the entanglement of old enemies, he gathered the oppressed Sanren players and formed the "Sword Market" guild. Together with swordsman Li Rui, Danxiu Lin Xiaowan, and formation cultivator Zhao Lei, they used elixirs to consolidate the foundation, defend enemies with formations, and break the situation with swordsmanship, step by step against the monopoly and pursuit of Tianyan Sect.
As the plot progresses, Yun Jinghan searches for sea spirit tokens in order to open the secret realm of the fantasy sea, and gradually becomes aware of the secret of the integration of the "mysterious realm" and reality, as well as the potential threat of extraterrestrial demons. From killing the boss in the novice village to establishing authority in the guild, from personal revenge to protecting his partners, he uses the sword as his edge, not only to rewrite his own destiny, but also to carve out a way for mankind to survive in the crisis where games and reality intersect.
