Transmigrated to Another World, I'm Lawful Neutral

My name is Cao Yixuan. The Xuan in Xuanyuan. I am a man who made a deal with the Grim Reaper. “What do you want?” I asked. “A heart. The heart of a king.” The Grim Reaper held a massive book. The mask on his face made his expression impossible to read. Ten minutes ago, I was shot and killed in Myanmar. As I hovered between life and death, the Grim Reaper emerged from a gate in the void, ready to take me back to the underworld. “You seem to have a few regrets. How about we make a deal?” I had never seen the Grim Reaper before, and I didn't answer. Not until... The Grim Reaper plunged his hand into my already phantom-like body.
