Star Breath Quiet Fire

Star Breath is the breath of the stars. God has left long ago, leaving only an eternal law. In this world, magic can be measured, soul durability can be calculated, and all power has a price. Every time a spellcaster steps on the line, they consume irrecoverable souls. Forbidden magic leaves indelible magic marks on the earth. The blank magic power of the attributeless people is the only scalpel that can perfectly peel off pollution, but they themselves are sold as "perfect medicine" on the black market. Su Jin is a time traveler. In his previous life, he failed to start a business three times. He committed suicide by holding his breath and was saved by his body. When I opened my eyes again, I was lying in a strange wasteland, ten years younger. This is a dark and heart-warming story. The world is cold, but people are warm. It's not the most powerful spell, it's the fire that burns the longest.
