Arc of Fire - Chapter 727: "12345, it’s five pairs of weighted wheels!

In his previous life Bai Lang was a small star. He rejected his boss and stupidly engaged in a relationship which he thought was true love.

Emperor Ian Veroshion, the first noble mage, was betrayed and executed. Cursed to never be reborn, he awakens a century later as the illegitimate son of a disgraced ducal line, destined to be a hostage in a barbaric land. Stripped of his magic and his throne, he must navigate a world vastly different from the one he ruled, facing political machinations and a resurgent monster threat. But the embers of his past life still burn, and Ian will not surrender his legacy. He will reclaim his name, his magic, and perhaps, even his empire.

It’s a affair between a loyal dog servant and his master.
