Lin Zan had read the original novel, so he naturally knew that everyone under Jun Beiyu would wear such a token to prove their identity.

In order to prevent the enemy from knowing the identities of those people, Jun Beiyu did not carve any words on the token, but only had someone carve a ghost head with a ferocious expression.

When Jun Beiqi heard what Lin Zhan said, he nodded in understanding. But at this moment, his expression suddenly changed, and he vomited blood, with blood slowly flowing from his eyes and ears.

At the same time, Murong Hui's situation was not much better. His condition was even more serious. He fainted and blood was coming out of all his orifices.

"Hurry up and bring me my golden needle." Lin Zan said anxiously, and Lang Ya quickly brought the golden needle.

Lin Zan first sealed Jun Beiqi's acupuncture points, and then began to give acupuncture to Murong Hui. He was so busy that he was sweating profusely, but the conditions of the two did not improve at all.

"What kind of poison is this and why is it so strong? If I hadn't used the golden needles to temporarily seal their heart meridians, they would have died from the poison by now."

Lin Zhan said with clenched teeth, and it was already bright outside, they should go back to the palace. Bixia outside was knocking gently on the door.

If Jun Beiqi had not returned to the palace with Liu Qiuchan, it would have definitely aroused suspicion from the emperor and Jun Beiyu.

Thinking of this, Lin Zhan became extremely anxious, so he asked Langya to guard the two of them while he went to find Liu Qiuchan.

"Why is there a circle of dark circles around your eyes? Didn't you get enough rest last night?" Liu Qiuchan noticed that Lin Zan looked not well and asked with concern.

Lin Zhan came to Liu Qiuchan and whispered in her ear, "Sister, I have something important to tell you."

Seeing her serious expression, Liu Qiuchan waved her hand and asked the servants in the room to leave.

Lin Zan then told Liu Qiuchan everything that had happened to Jun Beiqi.

"What, can the prince be saved?" Liu Qiuchan was startled. She supported her stomach and sat down on the couch next to her, holding Lin Zan tightly and asked.

After all, the prince is on their side. If he dies, the throne will fall into the hands of others, and then the entire situation will change.

In order to comfort Liu Qiuchan, Lin Zhan could only say to her, "Don't worry, sister. I didn't study medicine for many years in vain. It's just that I need time. Sister, you still need to go back to the palace to deal with it. Don't let others notice anything unusual."

"This is a small matter, easy to deal with, Zhan'er. I'm leaving His Royal Highness the Crown Prince in your care. Our fate is tied to His Royal Highness the Crown Prince, so we must not let anything happen to him." Liu Qiuchan said to Lin Zhan with an admonition.

How could Lin Zhan not know about this? He nodded seriously.

In the end, Liu Qiuchan kept Lin Zhan on the grounds that Lin Zhan wanted to stay in Taoyuan Temple to pray for her.

As for His Royal Highness the Crown Prince, Lin Zhan asked Lang Ya to dress up as Jun Beiqi, and left in a carriage with Liu Qiuchan.

Then he used the excuse of having caught a cold and did not return to the palace to report. The emperor did not become suspicious, but instead told Jun Beiqi to have a good rest in the prince's mansion.

The matter was resolved, but Lin Zhan's heart did not relax for a moment. She was as anxious as an ant on a hot pan when she saw the two people who had been unconscious for a day.

Although the golden needle technique can ensure that the two people will not die, it cannot eliminate the toxins in their bodies.

After taking their pulses, Lin Zan had no idea what poison the two had been poisoned by. How could she not be anxious?

Lin Zhan wrote a letter about the two people's pulse conditions and asked Langya to deliver it to the palace to Lord Yuanzheng, wanting to see if the master had any solution.

But now Langya hasn't come back yet, so Lin Zhan can only wait for news anxiously.

Another half an hour later, Langya finally appeared in the room silently, and Lin Zhan hurriedly went to greet him. "What's the situation? Did the master say anything?"

"The dean didn't say anything, but just asked me to give this medical book to the young lady." Langya took out a medical book from his arms and handed it to Lin Zan.

Lin Zhan was very surprised when he looked at the medical book made of sheepskin in his hand. After opening it, he found a message from the dean to Lin Zhan inside.

“The person who tied the bell must be the one to untie it.”

Lin Zan was completely confused and didn't understand what Yuan Zheng meant, but she still quickly flipped through the parchment medical book to find a way to detoxify.

Time passed minute by minute, and Lin Zan finally found a case with similar symptoms to Jun Beiqi and Jun Beiqi in this medical book.

Sure enough, there was a treatment prescription attached below. Lin Zan was overjoyed and asked Langya to get the medicine according to the prescription.

After taking the medicine for another two days, Jun Beiqi and Murong Hui vomited black blood at the same time and woke up again.

"How do you feel? Are you feeling better?" Lin Zan hurriedly stepped forward to ask. At this moment, Lang Ya suddenly grabbed her and looked at the two mouthfuls of black blood on the ground with a strange expression.

Lin Zan followed his gaze and looked underground. Then he was surprised and quickly took a few steps back, because there was a strange object mixed in the black blood, and it seemed to be alive and still wriggling.

"Miss, it's a poisonous insect." Langya said with a serious look.

Lin Zhan was stunned for a moment, then gritted his teeth and said fiercely, "It's the poisonous insect again. Could it be that Princess Yingduo and the Ghost Mother did it? Could it be that they teamed up with Jun Beiyu?"

At this moment, Jun Beiqi had slowly gotten off the bed and came to Lin Zhan and said, "How many days have we been unconscious?"

"It's been two days, but don't worry, I've already dealt with the matters in the palace, you just need to rest and recuperate here." Lin Zan said quickly.

Murong Hui sat up with a livid face, looking at the black blood still wriggling on the ground, gritting his teeth in hatred. "It's the Gu poison again. Sooner or later, I will kill the Gu poison master of Xijiang."

When they said this, several people's faces looked very ugly.

At this moment, Lin Zan also understood what the dean meant by saying that the person who tied the bell must be the one to untie it.

The insect poison can only be suppressed but not completely eliminated, especially the evil poison that Jun Beiqi and Murong Hui were poisoned by. It is necessary to find the person who poisoned them and cooperate with the mother insect in the hand of the poisoner to completely eliminate the poison in the body.

"You are now adding poison to poison, so don't try to be stubborn." Lin Zan glanced at Murong Hui, sighed and said.

Murong Hui suddenly raised his head and looked at Lin Zan. "What do you mean by saying that the escaped princess of Nanzhao Kingdom has joined forces with Jun Beiyu?"

After he finished speaking, Lin Zhan did not hide anything and expressed his thoughts. After all, they were all tied to the same rope.

"If I'm not mistaken, Jun Beiyu is using the poison in the hands of the ghost mother to seize the gold mine and secretly develop his own power." Lin Zan said.
