After transmigrating as the first innate Blood-Winged Black Mosquito in the Primordial World, Fang Xuan opens his eyes straight into a tribulation lightning trial ten times more powerful than the one required for transformation. At the brink of despair, he activates the Great Dao Merit System. One hundred thousand merit points turn the tables, sending him soaring straight to the rank of a Heavenly Immortal!
He cultivates both the Dao and the Demonic path, using merit as a shield to protect his Dao heart and his mosquito bite as a blade to slay formidable foes. He teaches and guides all living beings to gather merit, and cleverly acquires spiritual herbs to forge sacred bonds. His lectures on Kunlun draw countless clans to pay homage; his attempt to claim a meditation seat at the Zixiao Palace angers the Sages; he battles evil dragons for the Pure World Green Lotus in the Eastern Sea, suppresses the Demon Spring in the West to claim the World-Destroying Black Lotus, and ventures to the Northern Sea to mend his bloodline, where he encounters Demon Master Kunpeng.
He establishes the Myriad Treasures Market as a neutral hub in the Primordial World, allies with the Wu Clan, aids humanity, and resists the Lich Clan, advancing cautiously through the great tribulations. With golden merit light in his left hand to cleanse all evil and devouring runes in his right to consume heaven and earth, he uses the Qiankun Cauldron to fuse the Dao’s rhythms of creation and destruction, and breaks the Heavenly Dao’s shackles with the Great Dao of Balance.
From a lone mosquito facing tribulation lightning to the Dao Lord of Merit, he crosses mountains of corpses and seas of blood, outlasts the Sages’ schemes, and carves out a path to sainthood through merit unique to the mosquito clan amid the chaos of the Lich War and Luo Hou’s corruption of the Dao!
