While Lu Zheng was busy searching for evidence, Lang Ming entered the palace to meet with the emperor. Emperor Wen saw Lang Ming hesitate, his expression darkening. With a hint of displeasure, he demanded, "Lord Lang! Could it be that someone dared to obstruct your investigation?"

Lang Ming quickly put on a flattering smile, "Your Majesty, please calm down! After a thorough investigation, I have found that this matter is related to Xiao Xiao. However, she is the future wife of the Fifth Prince. I am really a little worried!"

Emperor Wen narrowed his eyes slightly, glanced at Lang Ming, and sneered, "Humph! Even the Crown Prince Xiao Jinghan has been thrown into prison. If Xiao Xiao has truly committed a crime, just let her go and investigate! What are you so afraid of?"

Upon hearing this, Lang Ming fell to his knees with a thud, his body trembling: "Your Majesty! I am worried that if I continue to investigate, the Fifth Prince will lose face! I am extremely terrified!" His voice was full of fear and terror, as if he was afraid of angering Emperor Wen.

Emperor Wen looked at Lang Ming's helpless expression and couldn't help but feel amused. However, he couldn't show it directly, so he could only smile bitterly and shook his head. Then, he turned to look at Eunuch Gao beside him and signaled him to summon the Fifth Prince, Chu Chengxuan.

After a while, Chu Chengxuan walked into the imperial study and bowed respectfully to Emperor Wen. "Your son greets you, father! I wonder why your father summoned you this time?"

Emperor Wen smiled faintly and said in a relaxed tone, "It's nothing serious. I just wanted you to learn about the progress of the Wu'an Palace witchcraft case."

Upon hearing this, Chu Chengxuan immediately understood Emperor Wen's intention. He looked up at him, a firm look in his eyes. "Father, I understand your intention. If anyone dares to use witchcraft in the Wu'an Palace, they will be breaking the law and must be severely punished!"

Emperor Wen nodded with satisfaction and continued, "Lord Lang has now traced the clues to Xiao Xiao, but he is worried that this will anger you. After all, Xiao Xiao may become your principal wife in the future."

Upon hearing this, Chu Chengxuan stepped forward and helped Lang Ming up, a gentle smile on his face. "Lord Lang, you're worrying too much. Even if a prince breaks the law, he must be punished according to the law, let alone a concubine who hasn't even married yet! Just feel free to investigate this case boldly. This prince will never blame you!"

Lang Ming breathed a sigh of relief after hearing Chu Chengxuan's words. He glanced at Chu Chengxuan with gratitude, then bowed to Emperor Wen and said, "Your Majesty, with the Fifth Prince's words, I will do my utmost to investigate this case as soon as possible and give an explanation to Your Majesty and the Wu'an Palace!"

Chu Chengxuan turned to look at Emperor Wen again and said firmly, "Father, I have irrefutable evidence that proves the Crown Princess is involved! The poison that the Queen Mother and Mother were poisoned with was caused by the Crown Princess's personal maid!"

Emperor Wen's eyes instantly became extremely sharp. He stared at Chu Chengxuan closely and asked in a low voice, "So, was all this orchestrated by the Prime Minister?"

Chu Chengxuan thought for a moment and replied, "This requires Sir Lang to conduct an in-depth investigation to find out!"

Lang Ming's heart nearly leaped when his name was called! They even wanted him to investigate the Prime Minister, the head of all government officials? Did they really think his head was too strong on his neck?

Emperor Wen looked solemnly at Lang Ming and said seriously, "Lang Ming, please accept my order. We must thoroughly investigate the witchcraft case and determine if it has any connection to the Prime Minister! You don't have to fear anything. Remember, you have my solid support!"

Lang Ming respectfully accepted the imperial edict and then bowed and left the palace. Chu Chengxuan also bowed to Emperor Wen and said, "Father, I will take my leave first!"

Emperor Wen's face was filled with a fatherly smile, and he gently said to Chu Chengxuan, "Okay, you can go back! In the evening, Eunuch Gao will send you the folk music scores of the Nanyi region."

Chu Chengxuan's face lit up with joy after hearing this: "Thank you, Father!" He walked out of the imperial study happily and saw Lang Ming standing at the corner of the road. So he walked over quickly and said with a smile: "Sir Lang, do you have anything else to say to me?"

Lang Ming bowed respectfully and said, "Fifth Prince! I would like to ask you for evidence that the Crown Princess poisoned me!"

Chu Chengxuan raised the corners of his mouth slightly, and replied in a relaxed tone: "Oh, Your Highness does not have any so-called evidence!"

Upon hearing this, Lang Ming's eyes widened and he said in disbelief, "Didn't you just tell His Majesty that you have evidence in your hands?"

Chu Chengxuan's smile became brighter: "Hahaha, that was just a casual remark of mine. However, I can kindly remind Lord Lang that Xiao Xiao and Li Jingshu have actually been in collusion for a long time, and Li Jingshu's maid Bing'er has had contact with those alchemists!" After saying that, he looked at Lang Ming meaningfully.

Lang Ming was anxious: "What does this have to do with the Prime Minister?"

Chu Chengxuan rolled his eyes and hit Lang Ming on the head with his fan: "What a blockhead! Father wants to use this opportunity to remove the Prime Minister's secret agents in the palace! I don't know how you became the prefect of Jingzhao Yin. Is it because of your pig brain?"

After hearing this, Lang Ming thought to himself that if he wanted to find evidence, he would need to start with these few people. He looked at Chu Chengxuan gratefully and said, "Thank you, Fifth Prince, for your advice. I will do my best to find the truth."

After hearing this, Chu Chengxuan walked past Lang Ming without saying a word. Lang Ming touched his head, which was hurting from the beating, and sighed helplessly, but he had no way to vent the anger in his heart.

These people want all sorts of results, so they use me as a tool, making me do things that offend others! Well, since I'm dumb, I'll just take the blame for you! Alas, it's better to have a simple mind. At least I don't have to suffer like this!

In the Imperial Study, Emperor Wen sighed to Kong Boda, "Why has Old Fifth suddenly jumped out to attack the Crown Princess and the Prime Minister when they're down? I simply can't understand it! Could it be that Old Fifth also covets the position of Crown Prince?"

Kong Boda quickly lowered his head and responded, "Your Majesty, please calm down! The Fifth Prince doesn't hold much power in the court. He only likes to listen to music and rarely pays attention to other things! I believe that he is supporting the Sixth Young Master Luo!"

Emperor Wen shook his head helplessly: "What a bad fate! Luo Lingyue's chess game, I'm afraid more and more players will get involved!"

Kong Boda bowed his head and replied, "No matter who comes to play chess, they cannot escape from your Majesty's palm!"

When this news reached Nanyi, Xiao Jingyi was enraged and cursed uncontrollably, "Xiao Xiao, what a fool! I sent her to ruin Xiao Luo's engagement, and she actually got herself involved!"

At this time, a counselor standing nearby said, "This time, it was Luo Lingyue and Xiao Jinghan who set up a trap, which is why Miss Xiao fell into it! My lord, I'm afraid this matter will implicate Nan Yi!"

Xiao Jingyi narrowed his eyes slightly and said fiercely, "Immediately order the secret agents in the capital to eliminate Xiao Xiao and that group of alchemists! As for Xiao Jinghan and Luo Lingyue, they must not be spared either!"
