A Feast of LoL Skills from the Start, and I Become a Saint Through the Flesh

[Apocalypse] [Ruthless] Ye Han awakens in his student dormitory and realizes in shock that he has transmigrated to an Apocalypse where the zombie outbreak began several days ago. Luckily, a pleasant voice rings out in his mind just in time: [The Apocalypse has arrived. Summoner, choose one of the following three R skills as your transmigrator perk.] [1. Feast 2. Shroom 3. Last Breath…] What? You’re saying this skill has no mana cost and no limit on its growth stacks? Then I’m locking in [Feast] right now and stacking it like crazy! What? Kill a target inside [Realm of Death] and the stats you steal are yours to keep? Well, well. You’ve entered Lord Mordekaiser’s little realm. You think you’ll make it out alive? What? You even thoughtfully picked out my runes for me? You’re too good to me, System! Can you believe this? I’ll take [Grasp of the Undying] and [Gathering Storm], no question. “What stats? It’s all thanks to my own hard work and sweat!” His health bar has piled up into a dense black barcode. Ye Han rises above all living things and attains sainthood through his physical body! The terrifying zombies are nothing but stepping stones on his path to power. As time goes on, his attributes soar beyond the heavens. When an extraterrestrial god bent on destroying the planet unleashes a world-ending strike, Ye Han stands unmoved amid the terrifying torrent of energy. Once the blinding light fades, only the hem of his clothes is slightly dirty. The whole world is stunned. Ye Han: You think you can… kill me!!! (voice cracking!) [↖Death Realm!↗]
