Fantasy World Warrior

Magic and alchemy are the main themes of this world, but the story that happened to the young time-travel adventurer seems to be different from others. He learned ancient Eastern mysticism to bring electricity to the world, and built various machines to open up the barren land. Gather food widely, build high city walls, deal with the invasion of darkness, and guard against foreign enemies in the distance, elves? Dwarf? Dark people? Is their magic stronger, or is our mysticism more powerful? You have to believe me, this is actually an exploration (planting) and adventure (field) article. PS: This book is also called: "Things Between Eastern Mysticism and Western Magic"
