The betting point could be the casino itself acting as the banker, or it could be an outsider. If it is an outsider, the casino will take a cut, which is proportional to the betting stakes on the table.
Ning Cheng, having come to this betting point, knew the house was the banker here, and he intended to break the bank, naturally steering clear of ordinary gambling tables.
Moreover, right from the start, he cautiously tested and discovered that his Divine Sense was not hindered here. This greatly reassured Ning Cheng, further affirming that his Sea of Consciousness was not something ordinary cultivators could compare with. The casino must have had a highly advanced Divine Sense shielding formation, but it couldn't stop his Divine Sense either.
