Du Ruofei discovered through experiments that there was something wrong with the dosage of Datura pollen, so he picked up some and put it in his mouth. As a result, he immediately had hallucinations and regarded Xun Changhao as an alien, causing trouble all night long.Xun Changhao had no choice but to invite the doctor.After checking, the doctor said that Du Ruofei had been poisoned, but because the dose of poison was small, his life was not in danger.The next day, Du Ruofei woke up and concluded that Xun Changxian had inhaled too much datura pollen and had hallucinations before setting the house on fire and burning himself to death.
