This Shadow Is 100 Million Points Strong

"Swallowing + system + apocalypse + male protagonist's decisive killing + slap in the face" "There are manuscripts saved. Please feel free to add them to your bookshelf. Updates will definitely be great." Thirty years after the spiritual energy was revived, monsters were rampant and the city was reduced to ruins. I awakened the most useless shadow power, and was ridiculed by everyone as a "walking surveillance probe." Until that day, the system came: "Congratulations to the host for activating the 'Shadow King System'. The novice's task: swallow ten monsters with shadow." I controlled the shadow to wrap around a violent giant bear, and I thought it would fail. The next second, the giant bear disappeared out of thin air with all its bones and flesh, and the system prompt sounded: "The swallowing was successful, and the skill [Shadow Devour] was obtained. Do you want to integrate the monster talent?" Later, when the S-class beasts engulfed the city wall, I slowly stepped forward under the gaze of millions of survivors. The shadow spreads out like a tide, covering the sky and the earth. I gave a thumbs up to the desperate crowd: "Don't panic, this is a high-end game."
