Traveling Through the Three Bodies? Kill Cheng Xin First!

My name is Meng Kai, and I have returned from the last days of humankind. When the whole world worshiped Cheng Xin as her savior, I was the calmest security guard around her. The moment she took over the sword holder's staff, I drew my gun and pulled the trigger - blood splattered on the spot. Amid the shock and anger of the whole world, I held up the forged instructions and said in a cold voice: "This is the 'wall-breaking plan' jointly formulated by the Holy Mother and the God of Death. Her death is the first clarion call of the new era." From then on, I replaced fraternity with an iron fist and led mankind with absolute rationality. I don't need to be understood, I just need to be human and survive.
