Even though Fu Wan was the one who was in the wrong, she insisted that Bai Meiyue had made things difficult for her. She made a fuss, saying that Bai Meiyue wanted to take the crystal nuclei from her, which was why she deliberately didn't send anyone to fix the water heater, and when someone pointed out that Bai Meiyue had done it the last three times for free, she lost her temper with them, too.
In the end, Fu Wan simply declared that they were not going to hand any more crystal nuclei to Bai Meiyue and her team. Because of this very reason, they couldn't even purchase meat from Bai Meiyue because Fu Wan confiscated all of their crystal nuclei. They couldn't buy the meat even if they wanted to!
But if this continued, then the flesh and blood of Eldest Master Bai would starve to death before he was even born!
