Zhen Lang and Gu Jing have been childhood enemies for over twenty years and pretend best friends in front of their parents. Zhen Lang and Gu Jing’s source of happiness is defaming their enemy (each other) at every opportunity, dreading the day their parents’ match-making dream comes true.

Ajax was an orphan who survives a massacre along with his friends but unfortunately gets separated from them.

Fortunately, after a turn of events, he successfully gains a system which helps him increase his cultivation, but doesn't know what it is called.

But he knows one thing for sure, this system is very powerful and helpful in taking his revenge.

“Whoever you are, I am gonna find you”, Ajax mumbled himself with a disgruntled expression.

In a world where Summoning of an elemental spirit is done through a dream when they are 15 years old, Ajax with the help of a system and his summoned spirits sets out on a journey to seek revenge against the mastermind behind the massacre.

He always told me that he dreamed of me at night.
