Three years ago, the animals and plants on Earth underwent crazy and unexplainable changes that included transformations, reversions, and the addition of otherworldly species. And it was the start of a brand-new type of profession in the new generation of humanity – Monster Trainers, people who specialized in taming monsters.

Sixteen years after Lu Yi traveled to the world of immortal cultivation, the long-lost golden finger finally awakened.

Goldfinger is a simple task panel. By accepting and completing tasks, you can get various rewards.

Lu Yi was surprised to find that the tasks he posted were counted as completing them himself?

So Lu Yi embarked on the road of no return where he issued a task to himself.

Issue the task to yourself [Practice the White Cloud Swordsmanship Ten Times], and the level of the White Cloud Swordsmanship will be +1 after completion.

Issue the quest [Defeat the Outer Sect Disciple] to yourself, and get the precious Perfect Qi Condensation Pill after completing it.

Issue the quest [Breakthrough to the Foundation Establishment Realm] to yourself, and get the best magic weapon after completing it.

…………

Unconsciously, Lu Yi discovered that even if he became a saint and an ancestor, it seemed that there was no difficulty in it?
