The witch doctor squatted in front of Commander Xia again, looked, heard and asked carefully, then stood up and went to check the teacup that Xia Changke had used.

Then he inspected the lid of the teacup carefully, and said, "Commander Qin, the lid of this teacup has been smeared with gu leaf juice. Mix tea and water together, scald it with boiling water, drink it into your mouth, and the poison will quickly seep into your limbs, and by the time you realize it, it has already penetrated into your heart and lungs, and you are powerless to recover.”

After the Gu leaf juice is made into powder, it is white, which is the same color as the tea lid of the porcelain cup, which is difficult to recognize. After being melted in boiling water, the color is the same as the tea soup, which is difficult to recognize, and the original taste is covered by the taste of the tea. The smell is even more difficult to detect.

This Gu leaf juice is not an ordinary thing, put it in tobacco, inhale a little, it can make the heart beat faster, the blood flow around the body, presenting a feeling of ecstasy, but if mixed with tea leaves, Only then will people's lives be killed.

This kind of thing is difficult to extract. It is impossible for ordinary people and ordinary wealthy families to have this kind of thing. It is nothing more than the people in power of several big families who can own this kind of thing.

Everyone turned their suspicious eyes on Min Zhihang again, and Min Zhihang was furious: "How did this kind of thing get into the teacup? Who moved the teacup to pull these tea-serving boys over?" Give him a good beating, and make sure to find out who did the hands and feet."

Qin Wuyan looked across the crowd and landed on the second head of the Min family, but saw that the second head and Qin Wuyan looked away as soon as they met, their faces were gloomy, and there was an uncontrollable smile on the corners of their lips .

Qin Wuyan understood, waved his hand, and let the crowd disperse. As for the deputy commander of the guards in the priest's mansion and the guards brought over, they were all detained in the interrogation hall of the priest's mansion.

Qin Wuyan didn't care about finding the real culprit, but immediately blocked the news, cut off all the information in the mansion, and didn't let the news of Xia Changke's death spread outside the mansion.

Minhangxing originally planned to ask Qin Wuyan to interrogate the servants who served others, but Qin Wuyan did not refuse, but said: "You can be regarded as a suspect if you have a humble job. In order to avoid suspicion, it is more appropriate for the Patriarch to interrogate himself. If the Patriarch is too distressed, It's the same when it's handed over to the second master for interrogation."

Now that the Min Mansion has been divided, how could Min Zhihang hand over this matter to the second master for interrogation? What if it happened to him, so he decided to interrogate himself.

Xia Changke's sudden death caught him by surprise, and it was completely out of his current plan. In a hurry, he could only do his best and act cheaply.

Qin Wuyan recruited the newly appointed captain of the guard and the deputy commander of the guard, dispatched troops and made some arrangements, then got up and went to the interrogation hall.

The results of the interrogation have come out. One of the servants was favored by the deceased Commander Jin. He wanted to avenge Commander Jin. He bit himself to death. He stole the Gu leaf juice from the Erdang’s pharmacy and smeared it on Xia Changke’s face. On the cup, Xia Changke was poisoned to death.

After all, afraid of being punished, he immediately bit off the poison sac hidden under his tongue, and died.

Min Zhixing was upset, but he could only present the result and hand it over to Qin Wuyan to deal with the aftermath.

Qin Wuyan dragged the three corpses, and went to the priest's mansion with the mighty guards from Min Mansion who were supposed to escort Commander Xia to surround the priest's mansion...
