Super-Dimensional Deduction: I Use Modern Science to Kill Gods

I have witnessed all futures, and all human beings, without exception, have perished. So, in the distant past, I committed a heinous crime. I personally put on the yoke called "sanctuary" for my people, making them submit to the servitude of the gods. At the cost of my dignity, I stole the fire that kept civilization alive. I am a sinner of history. I have also looked to the end of time and witnessed the last creation of our race - super-intelligent AI, which is the only weapon against gods and demons. Now, I, Zhang Linshan, a dying person from the future, carrying this last fire, traveled back to this world that was shaped into a cage by my own hands, and returned to my dying self. My mission is clear and cruel: in this desperate present, use this future weapon to execute the final [God-killing Plan]. It is I who put the shackles on mankind. Now, I will break it with my own hands.
