Interworld Time and Space Trader

On his way home from a late-night shift, Qin Feng is struck by lightning and unexpectedly gains a pocket dimension, along with the ability to travel through time and space. Through the dimension, he reaches Qiyuan Star, where people from Blue Star have migrated to the stars in the future. Qiyuan Star has suffered a nuclear war and is now short on supplies. Qin Feng uses his time-travel ability to bring supplies from Blue Star to Qiyuan Star in exchange for future technology, leading Huaxia back to the pinnacle of the world. I’m not very good at writing introductions, so please read the story!
