The scene of Yu Han flying over her head just now was too much of a blow to Su Lan. It made her feel aggrieved and humiliated. She wanted to vomit blood when she thought of how the audience would see Yu Han's powerful scene after the show was broadcast and how she was so frightened.
Not only was her efforts wasted, but it also benefited others for nothing. It was embarrassing. Most importantly, if they lost the competition, they would have to eat those disgusting bugs.
Although Su Lan usually liked to put on an act, she was not someone who was good at enduring. Her temper was not very good either. Otherwise, she would not have publicly wanted to slap Yu Han in front of the camera in the morning. Hence, under the repeated stimulation, most of her rationality ran away.
