Thanks for the chapter!
That is so funny. MC knew Shenshi and Chenyu would imply something about the food so got prince to lend the imperial chefs to make it. Now those two can't say anything bad about the food without insulting the imperial family. Considering the doctors can tell various things Shenshi probably took something to become sick to avoid being outed for faking, but likely to be discovered for poisoning herself instead now that imperial chefs were insulted and can't use position to frame MC.
