Lin Jian, an orphan from a hidden sect, appears to be an ordinary courier who shuttles between urban buildings, but in fact he possesses the rare Thunder Spirit Root and the ancient sword fetus [Xuanxiao Sword Heart]. A special mission involved him in a shocking conspiracy to destroy the ancient dragon clan, and he accidentally fused with the mysterious power that represents the end and origin of all things - the "Return to Ruins Source Crystal".
From then on, the ordinary urban appearance was torn apart before his eyes. The express station is a spiritual hub connecting to the secret realm, the antique market hides the trading of magic weapons, and deep in the subway there are entrances to ancient battlefields such as the "Kunlun Ruins". Lin Jian uses his identity as a courier as a cover to explore the lost secret treasure of cultivation, practice peerless skills, and deal with various forces and monsters in seemingly ordinary urban daily life.
He started out as a despised little person, and relied on unique opportunities, awakened "forest guard" blood wisdom and tenacious perseverance to solve many mysteries. Not only does he have to track down the bloody truth behind his family's annihilation, and fight against the "Tiandao Alliance" composed of ancient traitors and their descendants (such as the True Lord Tianlong in the Void Refining Realm), he also shoulders the heavy mission of guarding the origin of this world and repairing the ancient seal.
The road ahead is the neon lights of the city, and behind you is the fog of the secret realm. See how Lin Jian counterattacked and rose up in the bizarre modern world of cultivation with the sword in his hand, and embarked on a journey to the top of his own chivalry, shocking the entire world of cultivation.
