Lin Zhan remembered that in the original book, there was once an incident in which a foreign princess came to Northern Qi to marry a foreign princess.

At that time, Jun Beiyu had already married Wang Lanye, and his heart was still with Si Xueyi, so he didn't care about the foreign princess at all.

However, the power represented by the foreign princess made all the princes covet her.

However, among all the princes, there are only three who are of the right age, namely Jun Beiqi, Jun Beiyu and Jun Anqing.

At that time, Jun Beiqi had been deprived of his position as crown prince and was out of favor, so he was naturally not worthy of this foreign princess.

In addition, Jun Beiyu had already married a wife, and the foreign princess could not be a concubine, so the foreign princess was betrothed to Jun Anqing.

But now the plot has changed. If Jun Beiyu does not marry Wang Lanye, and this foreign princess appears again.

So for Jun Beiyu, who is extremely eager for power, he will never miss such a good opportunity to win over forces.

Thinking of this, Lin Zhan quickly calculated the time in his mind, but suddenly found that there was still a month before the foreign princess came to Northern Qi for an audience.

But Lin Zhan didn't know that everything she was thinking in her heart was heard by Jun Beiqi.

Jun Beiqi, who was reborn, naturally knew about this matter, but he didn't think of it for a moment, and looked at Lin Zan with a sparkle in his eyes.

At this moment, Lin Zan did not notice that Jun Beiqi looked at her strangely. She was still thinking about how to delay time so that Jun Beiyu and Wang Lanye could not get married.

At this time, Jun Beiqi, who was standing aside, spoke up. "Although my father cares about the royal family's reputation, he is not a man who kills indiscriminately. As long as Jun Beiyu's health is not good, Jun Beiyu and Wang Lanye will not be able to get married. We can delay for a day and find a solution."

Hearing him say this, Lin Zhan's eyes lit up instantly, and he clapped his hands and said, "Yes, as long as Jun Beiyu is not in good health, he and Sister Wang cannot get married."

"This is the only way for now. However, I heard that the Dean is in charge of Prince Heng's treatment. It may be difficult to hide this from the Dean's eyes." Liu Qiuchan said worriedly.

Lin Zhan also nodded, but still patted his chest, indicating that the two of them would take care of the matter.

After the three of them finished discussing the matter, Jun Beiqi planned to leave the palace, but before leaving, he turned around and said to Lin Zhan, "You can tell me anything. You know I will protect you."

Hearing his words, Lin Zhan was a little stunned, but still said with a smile as usual. "I know how good the Crown Prince is to me."

Seeing that she still looked like she didn't care, Jun Beiqi felt a pain in his heart. He turned around and left without saying anything else.

After returning to Hanfang Pavilion, Lin Zhan wrote a letter and asked Langya to give it to Murong Hui, then he retreated into the room and began to prepare the medicinal powder.

Late at night, Langya would always rely on his superb martial arts skills to sneak into Prince Heng's mansion quietly, and then sprinkle the powder under Jun Beiyu's bed.

This powder can evaporate with the moisture under the bed and has no smell, so it can cause Jun Beiyu to be poisoned continuously without him realizing it.

As expected, after taking the medicine for seven consecutive days, Jun Beiyu's condition did not improve at all, and even tended to become more serious.

Seeing her son's complexion becoming uglier day by day, Concubine Qin was naturally distressed, so she alarmed the emperor.

After learning that Jun Beiyu's physical condition had not improved at all, the emperor summoned the director to inquire.

"Your Majesty, the disease that Prince Heng is suffering from is very strange. I still need to make a diagnosis before I can make a decision." The director of the court said with a frown.

The emperor nodded and ordered the director to make sure Jun Beiyu was cured and then marry him with Wang Lanye as soon as possible.

So the court director brought Qin Shang to Prince Heng's mansion again. As soon as they entered the house, they noticed that the atmosphere in the house was a little strange.

Although the medicinal powder prepared by Lin Zhan had no smell, the director still noticed something unusual when examining Jun Beiyu's body.

Moreover, Qin Shang also keenly noticed that there seemed to be a white powdery substance under Jun Beiyu's bed, but he did not say it out loud and concealed it.

After examining Jun Beiyu's body, the Dean prescribed a few more symptomatic medicines and then took Qin Shang back to the palace.

Qin Shang hurried to Hanfang Pavilion, looking at Lin Zhan with a smile on her face, he didn't know what to say.

"I heard from the little palace maid that Senior Brother just came back from Prince Heng's mansion. Could it be that Prince Heng's condition is unusual? Senior Brother, come to discuss it with me."

Lin Zan pretended to be ignorant and looked at Qin Shang with a smile.

Finally, Qin Shang sighed, walked up to her and said, "Master must have realized that you did this. Master's medical skills are superb. No matter what you want to do, you have to speed up."

Hearing these words, Lin Zhan's face showed some surprise. She didn't expect Qin Shang to stand on her side.

After all, Lin Zan had once been a disciple of Lord Yuanzheng, and she knew that some of her techniques could not be hidden from her master's eyes, and she also did not want to hide it from the two of them.

So he just smiled indifferently. "It's okay, a month is enough."

Just this simple sentence meant that Lin Zan admitted what she had done, and she only needed a month.

Qin Shang gritted his teeth and nodded. "Okay, Senior Brother knows. Senior Brother will help you."

After he finished speaking, he was about to stand up and leave, but Lin Zhan stopped him and said tentatively, "Brother, I remember you got lost from your brother when you were young, but it's true."

Not knowing why Lin Zhan suddenly brought up this matter, Qin Shang nodded. "It is true."

"Senior brother helped me, so I will give him a surprise." Lin Zhan tilted his head with a smile, thinking that some things should be said.

Qin Shang's face was a little excited, but he soon returned to normal. He looked at Lin Zan meaningfully and left.

Qin Shang had thought about looking for his lost brother over the years, but so many years had passed and finding him was like looking for a needle in a haystack, and he was trapped in the palace and couldn't get out.

Therefore, over time, Qin Shang suppressed this idea in his heart and dared not think about it.

After Lin Zhan finished grinding the powder in his hand, he gave today's powder to Langya and said, "Press the acupuncture points of King Heng and let him inhale the powder while he is asleep. Don't let others notice."

"Yes, Miss." Langya put away the powder, then hid in the dark diligently, waiting for it to get dark.
