Lin Chen, a modern social animal, accidentally traveled to the early years of Zhenguan, which coincided with the founding of the Tang Dynasty. Hundreds of wastes were waiting to be revitalized, but there were also hidden internal and external troubles - Turks on the border were eyeing them, Japanese pirates were constantly harassing the southeast coast, there were many factions in the court, and people were still hungry and cold. Just when Lin Chen was at a loss, the "Prosperous Emperor System" was activated and bound to the system mall. By completing tasks and accumulating reputation, he could redeem various modern items, ranging from improved farm tools and penicillin to steam engines, flintlock guns, and even basic industrial equipment and various technical drawings. Since then, Lin Chen has relied on modern people's knowledge reserves and systematic blessings to start a legendary life in the Tang Dynasty, from establishing himself to becoming king and dominating, and finally achieving global unification.
