Struck by Lightning, I Got a System and Transmigrated to Help China in the War of Resistance

By a twist of fate, a recent college graduate is struck by lightning and gains a System. At first, he thinks it's nothing special. But once the System can take him through time and transport supplies to the past, he becomes intrigued. As a patriotic young man, he naturally wants to use the System to do something worthwhile. Before long, his actions catch the country's attention. The government sends the military to negotiate with him, and a fierce battle breaks out in a parallel universe, in that other era.
