Princess, the Courier Wants to Rebel

Modern courier Zhang Buyan falls into a deep pit with his tricycle and wakes up in the famine-stricken Dagan Dynasty. Facing refugees, he uses a glass marble to refract colorful divine light, calling himself the 'Mountain God Courier Envoy', escaping death and gaining his first followers. From then on, he uses modern courier services to dominate the ancient world: glass beads worth a fortune, three hundred Tang poems to become the God of Literature, a 'lightning stick' sweeping the martial world, and a bottle of perfume capturing the heart of the Sixth Princess. His broken tricycle charges across the battlefield, earning him the title of Regent King with power over the realm. However, after he kills the tyrant and supports his beloved Sixth Princess Dongfang Yuzhu to ascend the throne, he is thrown into death row—it turns out that from the county magistrate's recommendation to the siege of Beiliang, and even the emperor's massacre, all were part of the 'innocent' princess's grand scheme to seize power. Zhang Buyan saws through his chains, escapes to the enemy state Beiliang, and allies with Queen Lan Meier. He turns modern knowledge into gunpowder and fortresses, marching south. Meanwhile, Dongfang Yuzhu has become a Land Immortal, able to command reality with words. In the final battle, Zhang Buyan uses the 'time-space key' from his穿越 to open the nine layers of hell, permanently suppressing her. In the end, Zhang Buyan ascends the throne, marries Lan Meier, unites the two kingdoms, and ushers in a golden age.
