Return of Tower's Phantom - Chapter 20 – The Real One Awakens:

Humanity’s home is no longer Earth. Intersellar travel is now a common occurence, and technology has replaced blood and flesh.Luka, who grew up in the slums, has turned fifteen and taken the selection exams. His aptitude is of the “Imperial Guard.”

Viserys Targaryen was born with the blood of dragons and yet lived his life in exile. He was a prince with a lost kingdom and a fading legacy, an immature bastard who died a pitiful death. Unfortunately, that same death was coming for me now… as I found myself in his body right before molten gold fried my brain.Yes. Fuck Khal Drogo, and fuck the molten crown.With the memories from another life, in this world of betrayal and broken oaths, I had the chance to forge a new destiny for myself. Armed with the knowledge of the future, my own cunning, and [The Dragon System], I made the choice to flee from the Dothraki barbarians and take back what was rightfully mine.

System, “You have a sickness. Moreover, you’ll have one in every world.”

Hao Ritian, “…”

System, “What’s wrong? Is there a problem?”

Hao Ritian smiled, “No, there’s no problem. I was just a bit excited.”

System, “…”

That smile intensified the system’s feeling of ominous foreboding. It has had this premonition since it learned the name of its host. Now it only prays that this is all its imagination!

Ps: Protagonist shou 1v1, the gong is always the same person.
