- Description from novelbuddy

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.

Seratus tahun yang lalu, Ordo Cahaya mengalahkan Raja Kegelapan dan mendirikan pemerintahan yang mereka sebut era perdamaian.Namun, di balik senyum para penguasa Cahaya, tersimpan sistem yang menindas. Orang-orang yang dianggap “kotor” atau “berbeda” dimusnahkan atas nama kemurnian. Siapa pun yang mempertanyakan Ordo dituduh sebagai pemuja kegelapan dan dihukum mati.Namun, ada rumor yang mengatakan bahwa sisa-sisa kekuatan kegelapan perlahan-lahan bangkit. Seorang pemuda misterius bernama Kaelen, yang memiliki darah gelap, mulai mengumpulkan pengikut untuk menumbangkan tirani Cahaya. Mereka tidak bertarung untuk menghancurkan dunia, tetapi untuk mengembalikan keseimbangan dan mengungkap kebohongan Cahaya.
