At the beginning, he was indeed very proud and arrogant, but he gave in after witnessing Gu Ning's abilities. She had won a fortune three times in a row!
Although he was reluctant to accept the result, he didn't want to embarrass himself again by acting against her. It wasn't worth it. He had already been greatly humiliated.
In fact, except for Lucas, all the other foreign gamblers were humiliated publicly this time. They had lost the most money ever to Gu Ning.
At their first meeting, Hidesuke Ida had challenged Gu Ning, but Gu Ning never seemed to be interested in gambling with him.
Hidesuke Ida wasn't dumb after all, and he wouldn't want to gamble with Gu Ning. In addition, Gu Ning didn't care much about his unkind words. Hidesuke Ida had lost a lot of money to her, which was enough to teach him a lesson.
She wouldn't let Hunter go simply because he had paid a killer to murder her. She just paid him back.
