This situation... This must have been a gun barrel against his head. Unable to see or sense with his feet not on the ground, Jan Ren instinctively let out a loud roar, not even thinking at that moment. A mighty, inhuman roar; shaking the entire establishment so much so that the goons far from the corridor were hindered by the loud sound as well. And if they had a hard time functioning with the roar, assume that is what knocked off the offender as the object left contact with the Sinese' head; his arm loosened. It didn't matter what this was; it was time for a counterattack.
If he couldn't see his opponent or track them by the smell, that means he's in immediate danger even if the other was hindered. But that roar just now managed to paralyze the invisible force and as such one could deduct that it's at least human, or had human-esque hearing. Hurrying to move, the young man used one of his spells to raise a boulder from the floor, underneath himself as well; damaging his own armor in the process, but finding it suitable; as a loud grunt followed, signifying the attack's success.
From there, the young man continued to dash forward; finally entering the final room, to witness a shriveled old man simply seated upon a Joyan pillow by a tea table. In his hands, nothing. No form of protection. But the room itself was decorated with artistry and jewelry like none could imagine. The old man sat there, smoking from a pipe; right by a ginormous bed. Seems Jan Ren had woke him up. "Taru-gumi's boss, I presume..." He started, panting heavily as he made sure to rest for a moment, seismic sense at work to detect any upcoming assaults.
"...You've done well to come this far." The old man said, looking to his unwanted company. "You've given some trouble to my men... And stole from us while pretending to join our ranks. And now you're here again. Are you truly planning to crush us?" He asked, raising an eyebrow. "This entire district is under our protection. If you take us out, these businesses and establishments will have no one to protect them... You're effectively disturbing Hosenka's peace, you know." 'Peace my ass,' he thought. "Is that so." He asked degradingly as he took a leap forward, sweeping his leg in a wide arc before the old man managed to pull out a gun from seemingly nowhere; his head kicked firmly as he was knocked unconscious.
"Well, your protection isn't needed anymore. From now on, our Tenma-gumi will take charge." He declared, having his way with the numerous fortunes the back room held. With the boss out, Jan Ren had conquered yet another establishment. Wonder where that's going.
