Breaking The 'Barrier'
"Seems to work well, doesn't it?" Jin asked Kong Rong as he could see that communications were back up with a trick that the Dungeon Supplier had done. He tried to dupe the rules of the current dimensional instance by inserting his own dimensional instance through the barrier.
Usually, the interaction between various dimensional instances was rare since dungeon suppliers in this era did not have to collide with each other. Each of them had their own stores and there was no need to overwrite the dimensional instances. However, Jin did the 'rare' part way too often with his own dimensional instances.
He had to extend existing dimensional instances to suit a bigger crowd or even overwrite a few to let his customers enjoy the current gameplay without too much interference. But this was always within the System's domain so even with overwriting of dimensional instances, the risks were rather small.
