Ran Yan reached the house of the Xiao family. There was a layer of water lotus inside, and suddenly it went to another place. It was a small closed garden. There was a pond in the courtyard. Four words were seen on a stone: save him and save it. And this one is Xiao Song ’s nickname. In the Shang College, a guard suddenly fell to the ground, and Doctor Tai was informed that he had assisted Ran Yue to test the corpse and was frightened. He revealed that the person had typhoid fever and was suspected to be infected by those corpses. Ran Yan was immersed in the things he saw during the day, and unconsciously murmured. Xiao Song couldn’t help but hear it because it was his own nickname.

Soon after, the plague suspected by Tai Taiyi spread in Xiaofu, and Xiaofu was closed. Ran Yan was also infected and quarantined, and the prince and an inner waiter contracted the plague, which was confirmed to be Ran Yan’s infection. Xiao Song arrogantly guarded Ran Yan. Ran Yan had never been to the palace. How could he have seen the prince and the housekeeper. Xiao Song jumped into Ran Yanyuan anxiously, reassuring her that she would be rescued, and asked Ran Yan why she called her “Yan Zhi” yesterday.

This is her nickname, which was only called by Du Xinyi before. Ran Yan was a little uncomfortable after hearing it, but still assigned Xiao Song’s task, and asked him to ask Sang Chen to find some records of swollen “heart organs”. Sang Chen replied shortly that people would cause epidermal rashes and coughs due to certain external causes, and even hurt the heart and lungs, make them swollen, and even cause death. Xiao Song asked his first wife, Xiang Yao ’s maid, Qiu Hua to verify what Xiang Yao was allergic to. Qiu Hua replied that Xiang Yao could n’t stand “Shu Shuihua” and reminded Chunlai, who was in charge of the wedding, to remind Yutang Do n’t add Shu Shuihua, Xiao Song recalled that Xiang Yao died of a heartache after drinking a glass of wine after bathing. The analysis was that the wine accelerated the blood flow, which caused Xiang Yao to die of allergies. The most suspected spring came.

Xiao Song informed Ran Yan of the result. Ran Yan thought he was meritorious and asked Xiao Song to increase his reward. However, Xiao Song was found to break into Ran Yan’s hospital and was asked to leave immediately. Ran Yan felt chest tightness and went to take medicine after coughing. Xiao Song tortured Chunlai to force a confession, but Chunlai denied it. Xiao Song found clues in Chunlai’s belongings, proving that she was a guard at the gate.

Xiao Xiao Song instructed Bai Yi and Sang Chen to steal the food from his wife, Du Shi and the scorched corpse, hand it to Master Ran Yan, let the two rabbits eat it, and check whether they were poisoned before their lives. As a result, the rabbit that ate the food in the belly of the corpse died, but the rabbit that ate the food in Du Xinyi’s belly was not dangerous, indicating that the corpse did not cause the plague.

Bai Yi told Xiao Song that someone had created an illusion of plague, and Xiao Song passed it to Shang Shu. After further inspection of Jiao Zhe, he found that his teeth were black during his lifetime, which was the result of long-term chewing betel nut. Qin Taiyi, who saw Xiao Song for a doctor, liked to eat this thing, but he has resigned, and his successor Qi Taiyi is very suspicious, and everything can’t be related to him. The real goal is not Ran Yan or Xiao Fu, but the Prince. Xiao Xiaosong hurried to the prince’s dormitory and stepped over the soup medicine prescribed by Taiyi.

It was revealed that Qin Taiyi was bought a few years ago to make a medicine that could show the plague, but when Qin Taiyi learned that the drug dealt with the person who was afraid, the other party threatened him. He buried the medicine in Du Xinyi’s mouth and buried it. Then he resigned from the emperor, but with his own research effort, he sneaked back to the Xiao family to steal the medicine. After being found, he put the medicine in his mouth. The opponent was furious and smashed him with a lamp holder. Qin Taiyi finally died. The murderer burned the body and hid it in Du Xinyi’s coffin, but unexpectedly Xiao Song was going to open the coffin for an autopsy, so this murderer was Qi Taiyi.

Doctor Qi wanted to use the so-called plague to treat the prince, but he wanted to give the prince medicine and take his life. The bloodstains under the coffin lamp holder were left by Qin Taiyi when he resisted. When Qi Taiyi saw the matter exposed, he bit his tongue and died. The emperor read and Xiao Song rescued the prince, so he reinstated him as an official and gave him a prize. However, Xiao Song declined politely, so the emperor temporarily held the reward and waited until Xiao Song wanted it.
