There Is No System in the Apocalypse and I Am Very Panicked

I had just traveled to a parallel world, and when the end of the world came, my system swallowed up the system invented by the gods. The system I obtained from traveling also entered the update. It was really outrageous that his sister opened the door to outrageous things. It was so outrageous. I have no choice but to rely on my strong hands-on ability and wisdom to survive in the end of the world. I believe that as long as the system upgrade is successful, I will be in charge of thunder and lightning. This novel and its characters are purely fictitious.
