If that was the case, those big forces would definitely come to snatch the business, and the four price gang would not be able to stop those big forces.
Don't think that the ye family would help him just because Zhao Hai cooperated with the ye family. He was not that naive. He knew very well that if the ye family knew how much money they made from the earth-connecting potion, they would probably attack the four righteousness gang first. Although selling robots made money, for the ye family, the supply was always in the hands of Zhao Hai, which meant that all the supply channels were in the hands of Zhao Hai. This was something that a big family like the ye family could not accept.
But now, for the sake of profit, they had to accept it even if they didn't want to. That was why they had to cooperate with Zhao Hai and treat him well, because those robots could bring huge benefits to the ye family.
