Tang Seng and his disciples went to the west to learn Buddhist scriptures. One day, they went to a mountain village. Tang Seng asked Zhu Bajie to ask for some food to satisfy his hunger. It was the Lantern Festival, and the villagers donated some glutinous rice balls. Bajie tasted one. It was delicious, and he ordered it. The number of glutinous rice balls can be divided into four equal parts. Bajie was hungry and panicked, so he ate his own portion first. After eating, he still felt insufficient, and then secretly ate another one. Strange to say, the rest of the glutinous rice balls It can be divided into four equal portions. Bajie was overjoyed and couldn't help but eat another portion. Because the number of glutinous rice balls was very ingenious, Bajie still followed the method of the previous two times, and then ate it for the third and fourth times. When Bajie returned to the master, there were less than 100 glutinous rice balls. Question: How many glutinous rice balls did Bajie get back in total?
