A Journey to a Different World at the End of the World

(Travel to another world + super powers + two male protagonists + plot + emotional) A disaster caused by nuclear sewage. Let the earth become dilapidated in future generations. Biological mutations have launched a fierce war with humans. Complain about what happened to you. Human beings were affected and cannibalized their fellow humans, and were born out of this disaster riddled with holes. Ye Chu longed for the past civilization and looked forward to seeing the prosperity of the past. Until a mission, he came to a parallel world thirty billion years later. I learned that what happened here was a continuation of the original disaster and had not been erased by the passage of time. It still brings hardship to people in future generations. In order to save his homeland, Ye Chu made a deal with the gods. He rescued the parallel world and water and fire 30 billion years later, and God gave him a way to save the shattered family... When the truth behind the war is revealed bit by bit, where should we go? [In the early stage, the two male protagonists had many plot lines, and their relationship gradually improved and they became close friends who could risk their lives to protect them. They went through hardships and became stronger along the way. There will be a CP group later]
