Undertale: Man Is Underground and Hates Chocolate

A continuous rain led Shen Yan, a graduate student in the history department, back to the Shen family's old house in the ancient town of Duchuan. In a dusty camphor wood box in the west wing, a copper fish talisman engraved with Qin seals unexpectedly appeared. The fine characters on the inside of the talisman "The boat capsized at the river mouth, and no one of the thirteen people survived" actually echoed the mystery of the Qin Dynasty shipwreck unearthed at the river mouth in the 1980s. There are rumors that his ancestors were the governor of a water station crossing the river in the Qin Dynasty, the bizarre records of "there are monsters at the bottom of the river" in the fragmentary notes, the evil "Guimen Pass" waters described by the old people in the ancient town, and the giant bronze shadow flashing across the bottom of the river... Layers of mist enveloped Shen Yan. He followed the clues of the fish charms and bamboo slips, and with the help of his mentor Zhang Yanzhi, he joined hands with an old boatman who was familiar with the waterway, and stepped closer to the secrets deep in the river mouth. This is not only a historical trace spanning two thousand years, but also a pursuit of protection and inheritance. What kind of mystery does the post ship sleeping at the bottom of the river hide besides military rations? As a token of Shuiyi, why was the copper fish talisman kept secret by the ancestors of the Shen family for hundreds of years? When the ripples of the truth slowly spread in the water across the river, a past story about officials and soldiers in the Qin Dynasty that was buried by time will finally be revealed.
