Xiaofan concealed the fact that he was poisoned because he didn't want everyone to worry about him. Of course, being in Japan now was already cause for concern among them. Although his abilities were not weak, if they knew he was poisoned, those guys would definitely raise a ruckus.
However, apart from his family worrying about him, in Japan, there was also someone else concerned about him, and that was Leng Yue.
By the next day, Bai Xue and Leng Yue discovered that Ruyu had left without saying goodbye. Upon investigation, they learned that she had left with the captain the day before, but later, only the captain returned. Actually, there was no need to ask; it was already clear that the captain had given the antidote to Caterpillar to bring back, and then let Ruyu leave with him.
Xiaofan did not conceal his actions and answered truthfully.
