How I, Having Transmigrated into Li Yu, Restored the Tang Dynasty

When Li Yu opened his eyes, he had transmigrated into the body of the last ruler of Southern Tang, the man who wrote, 'Tell me, how much sorrow can one bear?' It was the second year of the Qiande era, eleven years before his kingdom would fall and he would be taken prisoner.

While the Northern Song was still measuring the world with swords, Jiangnan's arms factories were already mass-producing the next generation of firearms; While the Khitan cavalry still galloped across the grasslands, the steam engines of Great Tang were already starting up; While Europe remained shrouded in medieval darkness, fleets from the East were carrying goods and guns to knock on its doors. A poet emperor? No, a sovereign of all nations!
