Lu Xuanji, a modern tourist, was accidentally struck by lightning and his soul traveled through the Chongzhen period, becoming a "soul-catching demon" waiting to be executed outside the Meridian Gate. It happened that there was a severe drought in Beijing for three years. He held a mutated mobile phone to unlock the rainfall system. With just one photo, he summoned a downpour and narrowly escaped death. From then on, a down-and-out scholar transformed into the "Master Lei Gong" respected by both the government and the public. The suspicious emperor treated him as a distinguished guest, but the powerful eunuch Cao Huachun was secretly plotting against him step by step. Shen Ruolan, who was proficient in celestial phenomena, saw through his true nature, but chose to go hand in hand. He relied on weather forecasts to predict solar eclipses, relied on rainfall skills to resolve natural disasters, exposed demon deceptions and fought against palace conspiracies again and again. Skills cool down, magic weapons are damaged, rebels besiege the city, refugees press the border, and crises come one after another. From the Forbidden City to Taiyuan City, from court games to fierce battles in troubled times, Lu Xuanji used the mobile phone system as his trump card to survive step by step in the storm of the late Ming Dynasty. He must pretend to be a god to save his life, but also face the danger of the Ming Dynasty's collapse. When the ultimate thunderstorm and the secrets of time and space emerge one after another, can this "fake thunder god" from modern times change his destiny and hold up a world in troubled times?
