I Have Seen the Sea

Three thousand years later, the earth collapsed due to environmental collapse and civilization restarted, returning to the trajectory of the feudal dynasty. Daxia is divided into nine states, and He Yunshu, the concubine of the He family in Yongzhou, is possessed by a soul from the old era - Lin Wei, a doctor of biology, traveled through time, bringing with him all the memories of the deleted civilization. When she woke up, she faced a side courtyard without charcoal fire, a bowl of cold porridge, and a fate at the mercy of others. Her aunt wants to marry her off to an old, wealthy businessman. This world tells women that "having no talent is virtue." But with three thousand years of knowledge, she used arithmetic to break the situation, used laws to protect herself, and used strategies to exploit the gaps in power. She met Xiao Jue, the concubine of King Yong, and started from discussing business plans to sharing life and death step by step. They rescued people from drought, discovered the gene bank of the old era under the northern ice sheet, and defended Yongzhou City side by side in the bloody battle to seize the direct descendants. When the new dynasty was established, she promoted vaccination, women's schools, and the female official system. Every step was leveraging the thousand-year-old iron law. But the bigger truth lies underground - the old era did not die out naturally, but was artificially deleted by the organization behind the scenes who called themselves "Purifiers". They erased human memory every three thousand years, allowing civilization to cycle endlessly on a controllable track. She exposed the fatal loophole in the "Delete and Restart" vote and ended the three thousand years of eternal reincarnation with the "War of Heaven". After the war, she and Xiao Jue jointly governed Kyushu and presided over the compilation of the "New Kyushu Code", establishing the first law that "all people in Kyushu, regardless of gender, are born equal." And when everything was settled, she chose to set sail to the sea - beyond Kyushu, there were lands that had not been touched by "Restart".
