Jiang Chen was diagnosed with an advanced terminal illness. The travel agency on the verge of bankruptcy was burdened with huge debts, and his life entered a countdown. When he was about to die, he bound to the "Wanjie Cultural Tourism System". As long as he takes a group through history and completes the check-in, he can redeem longevity and rewards. From Emperor Qin's eastward tour to the moonlight of the prosperous Tang Dynasty, Jiang Chen took all kinds of tourists across time and space. When modern technology collided with the iron-blooded Qin army, Jiang Chen was not only rewriting the regrets of history, but also facing death in the eternal river and becoming the only king of time and space.
