The group of thugs was sent by a powerful man. Trying to reason with them was a simple waste of time. Moreover, Inala didn't wish to lose brain cells trying to hear whatever crap they had to say in order to take action against him.
Hence, he simply attacked first. His Prana Hand flew around and punched all seven thugs squarely in the jaw, knocking them unconscious. He then tied them up, thinking of a plan of action while waiting for them to get up.
Of course, Inala had already investigated the dynamics of the place before he bought it. Safara was a rather ambitious woman, keeping tabs on people in power. She used her smarts to manoeuvre her way through the political scene of the marketplace and emerge successful.
The past couple of chapters were a bit slow-paced. No worries though. Things will speed up shortly after this mini arc.
