Hell's Beginning: I Am a Military Advisor in Wuhu

I traveled to the bustling city of Luoyang. Under the iron hooves of the Jie tribe, among corpses everywhere, I was dragged away as a slave. In order to survive, I pointed to the sky and said to Shihu: "There will be a heavy rain in three days, and your bows and arrows will be useless." The heavy rain came as expected, and I became Shihu's strategist. When he massacred the city, I gave him the sword, when he killed people, I added firewood, and when he was scolded in the history books, I memorized half of them. It wasn't until the Yecheng construction site that I saw Shi Hu trying to bury three hundred Han craftsmen alive. Amidst the dust, a familiar face appeared - it was my proudest student before time travel. "Teacher!" His hoarse cry penetrated the blood. I suddenly clutched the gunpowder formula in my sleeve and bowed to Shi Hu: "Your Highness, if I spare their lives, I... Will create thunder and fire." Shi Hu's scimitar stopped at his neck and smiled ferociously: "Slave, are you worthy of negotiating terms with this king?"
