After Xuanyuan Zhiling heard Eunuch Li's words, he frowned slightly. Then, a complicated look appeared on his face as he said, "Eunuch Li, you don't need to make a decision so early, why don't I go and have a talk with Qin Feng first? But Eunuch Li still needs to tell me, what message did father give us?"

"The Emperor has said that if the wangfei is willing to enter the palace to treat his Majesty's illness, the Emperor is willing to cancel the marriage between you and Princess Soaring Wind Kingdom." When he said till here, Eunuch Li's face already revealed a faint anxious expression.

Hearing this, Xuanyuan Zhiling's eyes quickly flashed with a burst of light. Although he was extremely happy in his heart, on the surface, he did not reveal it at all. Instead, he calmly looked at Eunuch Li.

"Since Eunuch Li has already said so, then I can only go in and find Qin Feng." Xuanyuan Zhiling chuckled, he then walked towards Qin Feng's room, and before he left, he instructed the servants: Come, give Eunuch Li some tea, you really do not have eyes, can't you see that Eunuch Li is extremely tired?

Eunuch Li was arranged by the servants of the Duke's Palace to sit in the main hall, while Xuanyuan Zhiling walked towards Qin Feng's room.

Arriving at Qin Feng's door, Xuanyuan Zhiling's expression revealed a hint of happiness. He did not expect that the marriage alliance would be resolved like this.

"Qin Feng, I never thought that you would actually have a way. As you expected, the father made a condition, and as long as you enter the palace to treat his illness, he will cancel the marriage." Xuanyuan Zhiling reported the good news to him from the entrance even before he entered the door.

"Hmph, as I expected." Qin Feng slowly crawled up from the bed. Just now, when she heard that the Eunuch Li had come again, she originally wanted to continue lying on the bed to pretend to be sick. However, she did not expect that the Eunuch Li would bring such good news.

When Xuanyuan Zhiling walked in, he was already sitting in front of the table drinking tea.

"At that time, how did you know that father would definitely give such a condition?" Xuanyuan Zhiling frowned slightly as he asked with a trace of surprise on his face.

When Qin Feng heard this, she faintly smiled and said, "Because this is the only condition that the Emperor has for exchanging with me, no?"

"So you already knew that the father would use this to exchange with you." Xuanyuan Zhiling said faintly. After Qin Feng heard this, there was a pleased look on her face, but it only lasted for an instant.

"Can we go now? If the condition of the father is really delayed, it will be hard for us to escape our responsibility. " When Xuanyuan Zhiling said this, his expression was a little solemn, and the gaze he used to look at Qin Feng with was also a little anxious.

"Alright, let's go immediately." As she said that, Qin Feng was already holding onto the medicine box, preparing to follow Xuanyuan Zhiling into the palace. When the two of them reached the main hall, they saw Eunuch Li pacing back and forth anxiously.

When Eunuch Li saw the expressions of Xuanyuan Zhiling and Qin Feng, he was slightly overjoyed, and the anxious expression on his face also eased up slightly.

"Esteemed wangfei, this old servant has been waiting for you for too long. If you don't come out now, this old servant will die of anxiety. I can't even keep my head." When Eunuch Li said this, his eyes actually lit up with tears, the murky tears were so real.

Qin Feng only smiled faintly, and her expression carried a trace of coldness: "Eunuch Li is a popular person by the empress's side, why would he so easily lose his head?" Qin Feng's tone was a little relaxed, but what Qin Feng said actually caused Eunuch Li to have an additional trace of astonishment in her eyes.

"Right now, the emperor's illness has already reached a state of anxiety. Those imperial physicians who saw the emperor before were all killed by the emperor because they couldn't come up with effective medicine. If this old servant makes any more mistakes, this old servant's brain probably won't be able to hold on either." As Eunuch Li spoke, he looked at Qin Feng and Xuanyuan Zhiling with tears streaming down his face.

"Eunuch Li, don't worry. If the emperor blames you, I will definitely speak out for you." Qin Feng said with a determined look on his face. When Eunuch Li heard Qin Feng's words, she became more relaxed and wiped away the tears on his face, calming herself down.

"We should hurry into the palace right now, otherwise we really won't be able to save the old servant's life if we delay the emperor's illness." When Eunuch Li said till here, his expression carried traces of panic, and he urged somewhat anxiously.

Under the lead of the Eunuch Li, Qin Feng and Qin Feng arrived in front of the emperor's bedchamber. The emperor's condition was getting worse and worse, to the point that he had not attended the morning assembly for many days.

"Wangfei, the emperor has already lost a bit of patience from being tortured by the illness. I suggest that you treat the emperor as soon as possible. Once the emperor's illness is cured, he'll definitely give a reward to the wangfei." Eunuch Li looked at Qin Feng with anticipation when he said this.

"Qin Feng does not seek the emperor's praise. She only hopes that the emperor can fulfill his previous promise." Qin Feng said indifferently. While they were talking, the three of them had arrived before the emperor's bed. They saw the emperor lying on his bed with a worried expression. He was sighing from time to time. It seemed that his condition was getting worse.

When the emperor raised his eyes and saw Qin Feng, a look of joy flashed past his eyes: "Qin Feng, you've finally arrived. As long as you cure my headache, no matter what condition it is, I'll agree to it." The Emperor couldn't care less at the moment.

"Does your majesty's words count?" Qin Feng took off the medical case that she carried around, and asked with a slight smile on her face. When the emperor heard this, he vigorously nodded his head and said, "I am not joking. Could it be that what I say doesn't count?"

"Alright, since the emperor said so, then Qin Feng will definitely treat the emperor properly, but …" When Qin Feng said till here, she looked around at the maids and eunuchs hesitantly.

The emperor naturally understood Qin Feng's intentions, so he gave the order without hesitation: "All random people, get out. Eunuch Li will also leave first. Qin Feng and Ol 'Four will stay here." When the Emperor said this, his eyes actually showed traces of happiness. Thinking that his illness was about to recover, the Emperor's mood naturally became a lot better.

Thus, Qin Feng came to the front of the Emperor's Dragon Couch and sat down to feel the Emperor's pulse. Seeing this situation, the emperor naturally didn't dare to cooperate in the slightest. He could only obediently stay still and allow Qin Feng to take his pulse. Although the emperor had a splitting headache, he could only endure it.

"Qin Feng, what exactly did you see? "What disease did I get?" The emperor nervously asked as she saw Qin Feng's hand loosen from her own.

Qin Feng only let out a light sigh, and her expression actually carried a bit of seriousness. When the Emperor saw Qin Feng like this, traces of nervousness could be seen on her face.

"Your majesty, Qin Feng feels that what your majesty the emperor is suffering from is not an illness, but …" When Qin Feng said till here, her expression became a little solemn, and her gaze towards the emperor also carried a little suspicion.

The emperor saw that Qin Feng was in a difficult situation, so her expression became cold and she said: "Qin Feng, I order you to tell us now if you have diagnosed our illness or not. Otherwise, I will kill you just like those quack doctors. " The emperor seemed to have lost his patience by now. There were traces of impatience on his face.

Your Majesty, what you are suffering from is not an illness, but a poison from a voodoo Gu." Qin Feng's expression turned serious when she said this. Even Xuanyuan Zhi Ling, who was standing nearby, slightly frowned. He had previously heard people say that the poison of the Lich Gu was extremely poisonous, so how could his royal father offend such a sinister person for no reason at all?

Hearing that, the emperor was slightly startled, his expression carrying traces of doubt as he asked, "The Voodoo Gu's poison? What kind of poison is this? " The emperor's voice trembled slightly. It was obvious that he rarely heard of such a method of harming others.

"The poison of this voodoo Gu is more life-threatening than ordinary poisons. Not only can it poison you through the smell and food, it can also poison people through the skin, so this poison can make people even more invisible." When Qin Feng said till here, her eyes carried a trace of suspicion.

Hearing that, the emperor frowned, and said coldly: "We will naturally find out who poisoned us, but Qin Feng do you know how to cure this poison?"

"This is very simple, as long as we can find the source of the poison, and remove it. However, the difficulty of this poison lies in identifying it, and most doctors would think that it's a normal disease and treat it with ordinary drugs. It's actually completely useless." Qin Feng said with a complicated expression.

When the emperor heard this, he looked a little more relaxed. "Then you can cure Zhen's illness now. As for my investigation after he recovers, I'll need your help and Fourth Brother's help." The Emperor's face went slightly grim, and he had a complicated expression on his face.

"Your Majesty, has anyone come into contact with your relatively private items recently?" Or have you touched anything that doesn't belong to you, or smelled anything? " Qin Feng asked indifferently, she seemed to have a deep understanding of this type of poison.

The emperor pondered for a moment before suddenly recalling something. He said, "Recently, I've changed a type of incense. But this incense was personally selected by me. How could it contain the poison of a voodoo Gu?" The emperor frowned slightly. There was a trace of confusion in his expression.

"Then perhaps it is this strange aroma that caused you to be poisoned by this voodoo Gu." Qin Feng frowned slightly. If sshe wanted to cure the poison in the Lich Gu caused by its smell, he would have to cut off this source of fragrance and drink the special medicine that Qin Feng had concocted.

Xuanyuan Zhiling and the emperor both frowned when they heard this, because the two of them didn't expect that someone would actually want to kill the emperor. However, no matter who did it, their only goal was to usurp the Emperor's position.
