The Bottom-Tier Baron's Accidental Rise to the Top 3 - The Bottom-Tier Baron's Accidental Rise to the Top (manga), #3

LET THE SMEAR CAMPAIGN AGAINST THE INCOMPETENT COUNTESS COMMENCE Thanks to Baron Rize's wisdom (emphasis on the "dumb"), Babalon has brilliantly bounced back into beauty! To further develop his territory, Rize plans out a beach resort. Meanwhile, his resort rival, Countess Silica Palaceside has her hands full cracking down on the krakens crashing her coral reef and county commerce. Her plan? Kidnap some subjects who won't be missed and use them as live sacrifices to bait the krakens away...
Upon stumbling into evidence of Silica's crime, Rize hatches a scheme of his own: Blackmail the corrupt countess with evidence of her crimes to secure maritime rights for himself! Will he fight Silica one-on-one to monopolize resort tourism?! Thus begins the third act of the lord who never learns!
