In 223 CE, the first year of the Jianxing era of Shu Han, seventeen-year-old Liu Shan ascended the throne. Shu had just suffered a crushing defeat at Yiling, and the late emperor had entrusted his young heir to his ministers at Baidi. The whole country was in mourning. With the new ruler still a child, Zhuge Liang held the reins of government alone, yet the kingdom faced threats within and without: Cao Wei watched like a tiger, Eastern Wu had broken its alliance, and four commanderies in the south had rebelled. The treasury was empty, the people were exhausted, and the gentry of Yizhou were losing faith. Lin Yan, a modern young man who knows how the Three Kingdoms rise and fall, transmigrates into the body of a twenty-year-old commoner scholar in Chengdu. He knows that Shu Han's northern campaigns will drain it dry, its factions will become unbalanced, and its weak ruler will lead it to ruin. Armed with a thousand years of foresight, he resolves to lie low, bide his time, enter the court, and change Shu Han's fate. Some events in the timeline will happen earlier. A promising new writer's 100,000-character debut.
