Lin Qingya left the banquet alone, using the excuse of taking a walk in the back garden. She shuttled through the flowers with a serious expression, and kept recalling the scene of the secret passage in her mind. She vaguely felt that the secret of the blood jade was not as simple as it seemed on the surface, and it must have a deep connection with Li Rui's family and the current royal family, and Li Rui's disappearance was not accidental. She must find conclusive evidence to clear Li Rui's grievances and make the truth public.

While Lin Qingya was lost in thought, Ah Man appeared silently behind her. She was dressed in black and covered with a veil. She spoke in a low voice, but with a hint of vigilance, "Miss, someone is following you."

Lin Qingya nodded slightly, signaling Ah Man to pay attention to the surroundings, and then pretended to be nonchalant and continued to walk forward. While observing the surroundings, she used mind reading to perceive the thoughts of the people around her. She found that there was more than one person following her, and they were very powerful. She had to find a way to get rid of them before she could return to the palace safely.

"Miss, what should we do?" Ah Man asked in a low voice.

Lin Qingya's eyes flickered slightly, and a sly smile appeared on the corner of her mouth, "Follow me."

She walked towards a secluded corner, seemingly carelessly dropping a few silver needles as she walked, connecting the surrounding branches and flowers to weave a hidden net.

"Be careful!" she warned in a low voice.

Ah Man immediately became alert, his hand already on the dagger at his waist.

Lin Qingya showed a confident smile and quickly disappeared into the trees.

Li Rui sent the wine to test, and Lin Qingya took the opportunity to say that she was not feeling well and left the banquet. Li Chengqian saw that both of them had left, thinking that the plan had succeeded, and smiled triumphantly. However, he didn't know that Li Rui had already noticed his conspiracy and took this opportunity to secretly investigate.

"Someone, prepare some good tea for me!" Li Chengqian ordered loudly, with a smug look on his face, but he couldn't help but glance at the empty banquet hall.

Li Rui sent the wine glass to the study and handed it to the doctor in charge of the test. He said in a hurried tone: "Be sure to test it as soon as possible to find out whether there is poison in the wine!" As he spoke, he casually glanced at the furnishings in the study.

"Don't worry, Your Majesty. I will find out as soon as possible!" The doctor agreed, took the wine glass, and observed it carefully, his hands trembling slightly.

After a moment, the doctor came out with a serious look on his face, "Your Majesty, the wine was poisoned, but the poison is very weak and difficult to detect."

"Damn it!" Li Rui clenched his fists, anger flashing in his eyes, "This is obviously coming for Qingya! His Royal Highness the Crown Prince is really crazy!"

"Your Highness, don't you know yet?" the doctor whispered, "His Royal Highness the Crown Prince has already planned everything. He has anticipated that you will check the wine, so he has already prepared a non-toxic drug and mixed it in the wine to prevent it from being discovered."

Li Rui frowned, remained silent for a moment, and said, "I'll go find Qingya. He should have returned to the palace."

"Wait, Prince, you have something important to tell me!" the doctor said seriously, "Your Highness's target is not Qingya, but you!"

Li Rui was stunned. He asked in disbelief: "Why me?"

"His Royal Highness wants to take this opportunity to frame you and put you to death!" the doctor replied, "He has already had someone secretly monitor your every move. If you are discovered, you will be in danger."

Li Rui was shocked. He knew that the Crown Prince was ruthless and would not let him go easily. But he could not sit still and wait for death. He had to find evidence to expose the Crown Prince's conspiracy!

"I must find evidence against His Royal Highness the Crown Prince as soon as possible!" Li Rui said with a firm look in his eyes, "I will make his crimes public and make him pay the price he deserves!"

Li Rui quickly straightened his clothes, a look of sternness appeared on his face, and he walked out of the study quickly.
