The Law of Heaven Is Gone, I Use Technology to Conquer the World of Immortality

The way of heaven collapsed, the world fell into darkness, spiritual energy died, and the sect declined. In desperation, I took out the Type 99A main battle tank from my storage bag - it was actually a masterpiece that I had prepared for a rainy day and used my own spiritual roots to reversely refine weapons as the core of technology. When the ancestor of Yuanying trembled and recited the incantation, he shot out the weak true fire; when the real person of Jindan exhausted his magic power, he could only control the sword tilted and hanging in the air. But I controlled the "Immortal Destroying Cannon" and wiped out the Ten Thousand Demon Cave with one blow from a thousand meters away. The old devil shouted angrily before his death: "What is this evil weapon?" I responded calmly in the turret: "Dear, this is 'scientific cultivation of immortality'."
