All of those countries were enemies of Gu Ning's country, so they always behaved against Gu Ning's country.
Gamblers from the other foreign countries which had a good relationship with Gu Ning's country, like Country Y, had no hostility for Gu Ning. Instead, they hoped that she could defeat the best gamblers from Country R, Country M and Country H.
As for themselves, they would do their best and wouldn't be unhappy even if they lost.
Gamblers from the rest of the foreign countries were mainly onlookers who also wanted to win.
Everyone could join the game, as long as you weren't afraid of failure and could pay for the result.
Because all the best gamblers were very rich, the bet was a lot of money. It was normally millions of yuan and could even reach a hundred million yuan. Therefore, most people came to watch the drama.
They didn't dare to gamble with those gamblers, because they obviously couldn't win.
