Chen Mo, a plane-crash survivor, is stranded on a deserted island with flight attendant Lin Wei and twins Su Qing and Su Yu. Amid betrayal and desperation, they unexpectedly fall into a magical world, where they begin as exiles among the elves. Using modern knowledge, such as building waterwheels, Chen Mo earns the elves’ respect and saves Alice Frostblade, princess of the Frostwind Empire.
Following Alice back to her homeland, Chen Mo faces an orc invasion and political infighting at court. Drawing on the modern military principles of On War, he builds a powerful army with strict discipline and innovative tactics, including spear formations and volley fire. He wins repeated victories in legendary battles such as “The Funeral Song at Ice Lake,” helping Alice ascend the throne as empress and earning himself the title Duke Who Guards the Nation.
Chen Mo drives the integration of magic and technology, developing coke, magic crystal cannons, and railways. He helps Alice unite the human nations and establish the Sky Empire, which includes elves and dwarves. After crushing the million-strong orc army led by his archenemy, Zhang Biao, he brings the peoples of the continent together to sign the Sky Pact, ushering in an age of peace and prosperity.
However, shadows in the deep sea and strange tremors beneath the earth herald the awakening of the ancient gods. Using fragments of a rift, Zhang Biao awakens the world-ending evil god known as the Maw That Devours Worlds. Chen Mo rallies the entire continent, forges a god-slaying weapon, and leads his army into the divine realm. Though he pays the price of his eyesight, he ultimately slays the evil god and is revered as the Human Emperor. He co-rules a prosperous empire with his four beloved women, who each oversee military affairs, government, medicine, and intelligence. Yet as he runs his hand over On War, the book that caused him to transmigrate, he senses that the threats among the stars have not yet passed...
