The First Immortal in All Realms

The game otaku accidentally traveled to the world of cultivation, and came with a game system. With the help of the cold game system, he became the number one immortal in the world... Others need enough aura to break through the realm, a tough Taoist heart, and to survive the catastrophe, but as long as his experience bar is full, he will directly upgrade... Other people's equipment, elixirs, and magic weapons need to be refined, but he only needs to use the design drawings to synthesize them directly in the system... Others need to sign a soul contract to tame a pet, but he can capture it directly and upgrade the pet...
