Hunters of the Heavens: Becoming Stronger from Demon Slayer

[System, time travel, cool writing, relaxed, fast pace] Lin You was accidentally bound to the [All Heavens and Worlds System] and awakened the talent [Soul Hunting]: kill the enemy and plunder their power to strengthen himself. He is not a murderous maniac. There is no profit for innocent people, so he doesn't bother to take action - he is principled and cost-effective. But he is anything but a good man. When the benefits are sufficient or threats arise, he will be more ruthless and decisive than anyone else. Those villain bosses and sons of destiny have only one label in his eyes: "experience package". Kill you because you deserve to die or are in the way; rob you because it is useful to me. He travels across the heavens and completes tasks just by the way. Appreciating the scenery and becoming stronger are the serious things. He does not save the world, does not seek hegemony, and has no heroic baggage. Everything he did was just to live freely and freely in the world. The story of a rational, calm "predator" who only fights for himself.
