*****
Male Lead 1:

Born as a Godkin, a child of a female divine beast and a human male, Han Sungjun grew up to become an A-rank Hunter, a Black Commando in the Alsacian Federation, a union comprised of 18 countries in the Zuania continent. While reserves aren't that exceptional, he carries one of the most powerful ocular abilities in the world. But before he could reach his full potential, he ended up dead after a mission gone wrong in 1996.

Little did he expect that just before his death, a new power merged with his consciousness, giving way for his transmigration, 19 years into the future, into the body of Alexander Han, the Pakhan of Siberian Underworld, who leads Pavel, one of the strongest mafia gangs in the entire world.

Armed with a System that gives him the power of Overlord's Authority, a bionic eye that carries a Quantum Artificial intelligence software, enormous wealth, and power that he wields as the leader of Pavel, Sungjun's new journey is about to unfold.

Male lead 2:

Qin Tianzhu was a former elite of Shen Triad, a powerful criminal organization based in Siberia and Zuania continents, an archrival to Pavel.

Due to various reasons, he lives in hiding, as a store owner and an adoptive father to twins: Veronika and Theodore, who were his biological nephews. After a certain incident, he decides to go back to his homeland and proceed to live a new life, one that makes him stay close to his sister Xueli (the biological mother to his adopted children).

*
With Xueli being Sungjun's past life's sister-in-law and those two children being his nephews, Sungjun's path is bound to cross with Tianzhu. Whether they will become friends or rivals, it is up to fate.
