Genshin, Save the World!

My own method + alien invasion + apocalyptic farming + behind the scenes + Genshin Impact role-playing War never changes. But when a malicious civilization suddenly invades from another world, everything changes. Kinetic weapons cannot break through the enemy's shields and armor, and high pressure and high heat have limited effect on these horrific creatures that seem to come from hell. Even the biochemical weapons born from forbidden experiments have dissipated in the drastic changes in the natural environment as these invaders advance. The war destroyed the home of human civilization, and the survivors lingered in underground facilities. When human civilization is at stake, travelers from other worlds bring light! Gods, immortals, monsters, beasts and people from Teyvat came one after another, rekindling the fire of human civilization among the ruins and on the wasteland.
