Internet product manager Lin Wanrong died suddenly and traveled back to the Northern Song Dynasty to become a newly purified young eunuch. Being at the bottom of the palace, he did not despair, but used modern thinking to launch a counterattack. From the process reengineering of the Huanyi Bureau to the "PPT memorial" in the imperial study room; from the issuance of national bonds and the establishment of the Royal Bank, to the reform of the imperial examination and the development of overseas trade - he used the wisdom of a product manager to step by step become the powerful "CEO of the Song Dynasty". However, due to his great achievements, he chose to retreat bravely and live in seclusion in the south of the Yangtze River, running schools, writing storybooks, and adopting orphans. This is a story about time travel, counterattack, intrigue and seclusion, with laughter and tears, warmth and healing.
