At the beginning, I didn't quite like Seo Joo Heon. As a protagonist he's a bit unusual. He's smart, strong, yet cunning. And it's even more annoying how he used his relics to make his team members work like a slave.
However, the more I read it, the more I think why there must be something more than the Hamurabi Code relics to make the team members trust him and being loyal to him. After all, despite their complaints they all decided to join Joo Heon's party, put their trust on him, and work together as they did in the past.
The contract might be "slavery", but then again, Joo Heon knew how to put his trust to his team members. He protects them, and he actually knows how to give some appreciation to his team. And after reading it so far, I feel like that "slavery part" is actually only his way to make sure not being betrayed anymore.
I really appreciate him when he fulfilled his promise to Yoo Jae Ha to clean his name, even though by that time, he didn't know the full story of Jae Ha's role on Joo Heon and the team members' death.
And time to time, he showed that he protect the public. He has enemies, and knows how to make sure that these enemies whose actions endanger the public wouldn't be able to avoid their consequences.
He's not being heroic or having a glorious/noble vision/mission. He just wanted revenge on the companies who exploited him in and made him and his team members killed in thd past. He tried to make sure that these companies wouldn't be able to have it that way. And he did it cunningly. That's the kind of protagonist he is, and that's one reason why I found this story is interesting and decided to keep reading it.
Another reason why I really enjoyed this is because the fact that these relics was based on real person/artefacts from history, even if it's not the real person/artefact. I was able to learn a bit of history from these references.
