Lin Lei, the factory director of an instant noodle company on the verge of bankruptcy, unexpectedly discovers a space-time passage in his moment of desperation. Carrying a box of instant noodles, he falls into another world and saves Liu Shihan, the seriously wounded Eldest Princess of the Great Qian Dynasty. Resources are scarce in this other world, making instant noodles and bottled water priceless delicacies. To repay his kindness, Liu Shihan gives him gold bricks, helping him pay off his enormous debts. Thus begins his rise as a trader between two worlds. He transports modern equipment and systems to help Liu Shihan quell the turmoil and ascend the throne, while bringing back gold, priceless treasures, and miraculous medicines. Lin Lei makes his mark in both worlds, wielding immense wealth and power. In the modern world, he builds a financial empire; in the other world, he is bestowed the title of Duke Who Guards the Nation. Together with the Empress and a wealthy heiress, he embarks on an extraordinary cross-world legend.
