Mage Academy: I Have Infinite Skill Points - Chapter 294 - Those Who Don’t Know Aren’t Uuilty

Ethan wakes up expecting to see the walls of a hospital room—only to find a system message blinking in front of him:[Ding! You have killed a green worm][Ding! Green worm has been added to your summoning list]

In a world ravaged by radiation and the remnants of war, Dylan is far from a classic hero. A lieutenant with a tainted past, he's just trying to survive the ruins of a dying world... until the day he wakes up bound and surrounded by the mutilated corpses of his comrades.Captured by monstrous creatures, he soon realizes he’s been transported to another world. A world far more dangerous, far more brutal—where only the strong survive, and even monsters are hunted. Saved in extremis by Maggie, his commanding officer, he begins a desperate escape. Their only hope may lie in their encounter with Élisa, an elf abandoned by her kin, and their discovery of a mysterious power: anima gems—stones imbued with spiritual essence that can enhance body and soul, and unlock the path to awakening.No One under 18 admitted
