When I woke up, I found myself lying in a temple with grass taller than a person. My head was empty, my pockets were empty, and only a witch's robe was washed white. A stone lion who calls himself a "temple spirit" told me that I am the 372nd generation guardian witch here, with no monthly salary, no benefits, 24/7, and the only KPI is to protect this "great ancient ruins." Me: Good news: This ruins is big enough, birds don't poop, and it's quiet. Bad news: There are always unscrupulous people who want to come "treasure hunting." The first wave was tomb robbers carrying Luoyang shovels and saying "the king of heaven covers the tigers of the earth". I relied on the traps left by my ancestors in the ruins to send them to sing "Tears Behind Bars". The second wave is the "regular army" driving steam mechas and holding imperial exploration permits. I relied on... Well, relying on my mouth and familiarity with the terrain, I started a tunnel battle with them. I, an amnesiac miko, was forced to grow from a quiet (self-confessed) girl to an all-around security captain who is a trap master, negotiator, tactician, and archaeologist (half-baked) in order to keep my job (although I have no rice). My team is also growing day by day: an unlucky tomb robber who was cheated of all his equipment by me and had to stay and work to pay off his debts is responsible for technical support. A young officer who is full of passion, but is used as cannon fodder by his superiors in the empire, is responsible for... Being my cannon fodder. There is also a stone lion with a sarcastic mouth, who whispers "I remember those days..." In my ear every day. The days passed by in a battle of wits and courage, until one day, the imperial army surrounded the entire mountain.
