From the Start, I Moved Into the Prince's Mansion, and Now the Emperor Wants Me to Arrange a Marriage Alliance

Wang Jin wakes from a drunken stupor in another world, only to discover that he has become the Seventh Prince, a sitting target caught in a maelstrom of court intrigue. At court, his father's imperial edict conceals murderous intent. In the imperial study, one drunken remark becomes ironclad proof of treason. Outside the Cold Moon Palace, mother and son meet but dare not acknowledge each other... Even stranger, the ancient books in the Tiangong Pavilion are written in simplified Chinese, and the black miasma rushing straight at him seems to be watching his life. In this imperial capital, people are crueler than ghosts. He never expected that ghosts would actually exist.
