New Age Of Summoners NaoS

Ajax is 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 mighty and helpful in taking his revenge.
"Whoever you are, I am gonna find you", Ajax mumbled with a disgruntled expression.

In a world where the 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.
