The interstellar war has yet to end, and the Warring States have erupted into conflict once more.
Lin Jinan, the genius commander of the White Tiger Fleet, sacrifices himself to save his subordinates, taking his sworn enemy Zheng Qiuhong down with him. But they both transmigrate to a strange Warring States era. Here, the “Compassionate Ones” are protected by the laws of Heaven, and killing one brings down a celestial punishment of falling stars. If an emperor strays from the Way, disaster follows. Only those who uncover the truth behind the “Crime of Straying from the Way” can have one wish granted.
Lin Jinan becomes Shi Wenge, a young general, while Zheng Qiuhong becomes a princess with the same name, Qiuhong Ji. Hoping to return to the stars, Lin Jinan makes a pact with his most dangerous ally: she will help him ascend the throne and unify the realm; he will help her solve the mystery behind the disasters and fulfill her wish to return home.
From then on, the former interstellar commander takes up cold weapons, builds his reputation on the frontier, studies under a master, and wins the people's hearts, confronting the cruelty of war and the hardships of ordinary life. Meanwhile, the former fleet commander conceals herself deep within the palace, weaving a cold web of power as a young girl among the nobility.
When the horns of the eastern campaign sound and the road of slaughter and conquest begins, Zheng Qiuhong discovers that the only thing that can make him look back is a pair of clear eyes in the distance, always brimming with compassion.
This is a story of redemption and conquest across a thousand years. How will two geniuses from the future choose between personal bonds, the suffering of the people, and grand ambitions? Is the ultimate “wish” they seek a return to the sea of stars, or a future on this land below, where love and hate are intertwined?
