Searching for Comrades in a Parallel World

After his comrade dies because of him, Lin Yu is about to jump off a building when the comrade’s father tells him there may still be a glimmer of hope. To find it, he must use the watch his comrade gave him to enter a parallel world and search for his friend himself. (It’s not easy being a new writer, and my writing is still rough. If you don’t like the plot, please don’t attack the author. Thanks for your support.)
