Tiandao Trading System

Stuck in a realm and unable to break through? I have a peerless divine elixir that will guarantee your breakthrough to the Immortal Emperor! Want a magic weapon? I have a heaven-level spiritual treasure, a dragon-slaying sword, which can cut through iron like mud and break anything! Do you still need a Kung Fu manual? I have the god-level exercises here, "Yi Jin Jing", "Eighteen Dragon Subduing Palms", and "The Great Shift of the Universe". Just take your pick! PS: This is the story of Ning Xiaochuan's trade with the heavens and his conquest of all realms!
