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.

Zain Talen, your average college slacker, was busy skipping class to go play a new video game he had just bought, when a strange woman came running his way. Before he could get out of the way she collided with him. Quickly picking herself up she ran away leaving behind a pendant. Without knowing where she went Zain pocketed it and decided to look for her after his gaming session. During his binge, he heard it.

*Bang

His door was assaulted with the banging of someone who sounded desperate to get in. Rushing to open the door he found himself overpowered by something and not soon after felt a sharp pain on his neck. Vision fading in and out Zain found himself at death's door.

“Could this be the end?”
