Four people appeared and blocked in front of him. He almost fell down and stammered: "Rao..." "Spare me …"

When Liu Yanyu turned on the light, Gu Qingli looked at the light and asked in surprise, "Doctor Zhang?"

Doctor Zhang looked at her with his mouth agape and then said, "Yes, it's me. Why is Imperial Concubine Gu staying in the epidemic area?"

"Come out and look for the person who changed the medicine." She pointed at the warehouse behind Doctor Zhang that was filled with herbs. "What is Doctor Zhang doing here in the middle of the night?"

"I also suspect that there is a problem with the medicinal herb." Although I was not able to give a better prescription than the Gu side concubine, but from the pulse of my research, I concluded that the side concubine's prescription was definitely not a problem, and that the person who did the wrong thing was definitely the person who carried out the order. "I first thought that the medicinal herb might be replaced by someone, but I was afraid of alerting the enemy, so I decided to come in the middle of the night."

This Imperial Physician Zhang was extremely vigilant, and his heart wasn't bad. However, he gained nothing in return.

"Help us keep an eye out. It won't end like this."

"I've been paying attention for a long time and haven't found any problems with the person who gave the medicine to me, so I have a bold idea."

"Speak."

Doctor Zhang hesitated for a moment before revealing his speculations.

The next day when the weather cleared up, the soldiers and soldiers of the imperial camp who were guarding the epidemic area cleared a path in the snow. Some people were sent to the town to purchase medicines.

Phoenix Purple did as she usually did. There were a few people sent to the imperial camp to help her distribute the medicine. They chatted and interrupted her, having a very pleasant conversation.

Liu Yanyu and Gu Qingli, on the other hand, went out to check on the patient's recovery. Feng Zi calmly poured the medicine into bowls and watched them carefully place them in the basket and take them out one by one.

Gu Qingli was in one of the rooms, looking at the patient. When she saw someone put down the medicine bowl, she went up to him and picked up a bowl for a sniff. Her face immediately changed.

The bowl now had an extra pill. It wasn't poisonous, and the smell was light. However, when combined with her prescription, it would improve the efficacy of the medicine. As she had expected, the extra flavor medicine was definitely the cause of the epidemic going crazy.

Without a word, she told everyone to stop taking the pills and headed out the door.

When he arrived at the second room, Liu Yanyu was staring intently at a patient inside. He was currently raising his medicine bowl, wanting to drink it.

"Stop!" Gu Qingli stopped him in time and brought the medicine bowl to Liu Yanyu. "Do you smell something special?"

Liu Yanyu's sense of smell was not as good as hers. After a while, he answered in astonishment, "There is a medicine in this place. It is called Xin Poria, but it is non-toxic."

"Never let anyone consume it." Along with the voice, Zhou Qianxi hurried in, "This Xin Poria Cocos is indeed harmless, but you must not come in contact with the Green Gu. It will cause the Green Gu to go crazy, destroying the structure of the human body …"

"I already guessed it."

Zhou Qianxi frowned, "But I don't see anyone moving at all."

"That's because your mind is stuck on 'someone poisoned'." Gu Qingli smiled faintly. "With such preconceived ideas, your focus is solely on people, and you ignore the true nature of things."

Zhou Qianxi looked at her in astonishment. Liu Yanyu's eyes were also filled with confusion.

Gu Qingli poured the medicine into the medicine bowl and sniffed it. Then, she handed the bowl to Liu Yanyu, "Young Master Liu, smell it again."

Liu Yanyu sniffed two times and was silent for a moment before he raised his head. "There's something wrong with the bottom of the bowl."

"So, they don't need to play any tricks in the process of the medicine and delivery. Such blatant actions are too easy to be noticed by others."

Liu Yanyu sighed. Before this person had taken the medicine, he had already smeared the bottom of all the medicinal bowls with Xin Poria Cocos. After that, it was no longer important who took the medicine, who took the medicine, and who delivered the bowls to the simple shack.

"We can't blindly investigate this matter. The people who are in contact with us definitely aren't the ones we are in contact with." Gu Qingli stood up and said, "I want to go back to the inner city. Young Master Liu and Feng Zi are going to swallow it up. I don't want any flaws to be exposed."

"Yes."

Gu Qingli brought Zhou Qianxi out of the epidemic area and circled the area. This time, she had shadow guards protecting her, but they didn't find anything.

After entering the city, she rushed back to her home. Originally, she wanted to inform Xiaoyi Xiu to go find Lu Linghui, but she didn't expect that the two of them would have already discussed the interrogation in the secret room. Unexpectedly, nothing was found out, and so many people actually died without a sound, as if they had all perished in a short period of time.

Gu Qingli wasn't a stranger to this move, it had happened before in the royal hunting grounds. With just a slight mention of death, Zhou Qianxi said with certainty, "It was due to the insect poison, even those who seem to be normal would have it in their bodies, death is only a matter of time."

"Who is it?!"

To be able to kill a hundred people at any time, that was indeed a generous gesture.

If one were to talk about his conduct and style, it was hard to imagine that there would be anyone who would work hard for the person behind the scenes.

Lu Linghui did not say anything, but picked up the jade cup in front of him and downed it in one gulp.

Only now did Gu Qing Li smell the strong, cold wine aroma in the air. Xiao Yi Xiu never drank alcohol, and during the years he was poisoned, he was already used to not drinking at all, probably to entertain Lu Linghui this time.

Lu Linghui drank one cup after another, feeling extremely depressed in his heart. Seeing so many people die one after another in front of him during the interrogation, this unexpected turn of events caught him off guard, and Gu Qingli more or less understood his mood.

But wasn't what he cared about a bit too much? With the clues cut off, the one feeling even more depressed should be Xiao Yi Xiu.

"They're surrounded by the men from the imperial camp, but so many of them are already dead under his nose. He suspects that he has spies."

Only then did Gu Qingli understand that betraying any of her brothers could be said to be a huge blow to Lu Linghui.

"Vice Commander Lu doesn't have to be so sad. This might not be because of a traitor. In fact, the range of control for a Gu Master is different depending on their abilities. A Middle Ranker can control an area of a hundred miles."

Zhou Qianxi was the one who told her about this. When she heard about it, Gu Qingli sucked in a breath of cold air, feeling that things had become even more troublesome. How many people were there within a hundred miles?

Hearing this, Lu Linghui was stunned. His eyes widened in disbelief.

"This wangfei still has things to ask of the vice commandant. You'd better pull yourself together."

Lu Linghui's mood improved because of what she said. He immediately agreed and asked her what was the matter.

Gu Qingli told Lu Linghui about the outer city's Guo incident and had him quietly assign the task to go on. She had to find out who had poisoned the medicine in the bowl. After all, the bowl had been cleaned and used by more than one group of people. It would be too much of a waste of time to rely on her own strength.

Lu Linghui accepted his orders and immediately left the secret room. His manner was quite swift and decisive.

Gu Qing Li praised him, "Vice Commander Lu, you seem to be very straightforward."

"He's someone I trained before." Xiao Yixiu stood up and approached her, wrapping his arms around her as he sized her up. He felt as if she had become much more haggard after not seeing her for the entire night.

"How could Xiao Yijin allow him to stay in the Imperial Camp? How could he trust him for so many years?"

Xiao Yi Xiu said indifferently, "How can I let him know that I'm doing things? "He doesn't know the relationship between me and Lu Linghui. He was raised step by step over the years and originally planned to cultivate him into a trusted aide. How could he have known that it was me who had set him up beside him?"
