To The Land of Nevernight

After something horrible happens, a transmigrator can no longer sit back doing his inventions and farming shtick most other ancient-day farming transmigration novel MCs content themselves with. Instead he faces off against a scheming court as he tries to investigate the truth behind that incident, and accidentally gains a love interest he can’t be sure is trying to screw him over (before he realises he just wants to screw him) .
