Ah, you traveled through time too?

Li Yu said: "Although this operation was a success, the power of Mei Fei and Hei Yu still exists, and we cannot take it lightly."

Leng Ying nodded: "Your Highness, we will continue to monitor their movements and ensure that they can't cause any more trouble."

Liu Ruyan also said: "We will strengthen the defense of the palace to prevent the enemy from invading again."

However, just as they were celebrating their victory, urgent news came from the palace: the emperor suddenly fell seriously ill and his condition was critical.

Li Yu frowned: "Why did my father suddenly become seriously ill?"

The Queen Mother looked worried: "Yuer, you must go to see the Emperor immediately and find out the situation."

Li Yu nodded: "Don't worry, mother, I will find out the truth as soon as possible."

Lian Di and Lian Fang also said: "We will do our best to assist the prince and find out the reason why the emperor is seriously ill."

The situation in the palace became tense again. Li Yu, Liu Ruyan, Lian Di, Lian Fang and Leng Ying worked closely together to investigate the cause of the emperor's sudden illness. They suspected that this was another conspiracy of Mei Fei and Hei Yu and decided to investigate further.

The night was as dark as ink, and every corner of the palace was filled with unknown dangers. Li Yu stood in front of the window, looking at the deep night sky, and swore in his heart: "No matter what challenges I face, I will definitely protect this palace and my family."

Conspiracies and counterattacks are intertwined, the situation is changing, and everyone in the palace is fighting for their own goals. A more intense contest has quietly begun in secret.

While everyone was busy investigating the cause of the emperor's serious illness, a commotion suddenly broke out in the palace. It turned out that Mei Fei and Hei Yu's men had launched another attack, trying to kidnap the Crown Princess Liu Ruyan in order to threaten the Crown Prince Li Yu.

Liu Ruyan was surrounded by several of Hei Yu's men. She faced the danger calmly without any fear. She shouted loudly: "You traitors, don't even think about succeeding!"

Leng Ying, Lian Di and Lian Fang arrived quickly and started a fierce battle. Leng Ying defeated several enemies at lightning speed and successfully rescued Liu Ruyan.

Afterwards, Crown Prince Li Yu held Liu Ruyan's hand tightly, his eyes full of determination: "Ruyan, I'm sorry, it's my fault for not protecting you well enough."

Liu Ruyan smiled and comforted him: "Your Highness, don't blame yourself. I am fine. We must be more cautious to prevent the enemy from attacking again."

Li Yu nodded: "You are right, we can no longer take it lightly. I will mobilize more troops to strengthen the defense of the palace."

Just when everyone was worried about the safety of the Crown Princess, Leng Ying suddenly brought back an important clue. He seized a secret letter in the battle, which recorded the secret plan of Mei Fei and Hei Yu.

Leng Ying handed the secret letter to Li Yu: "Your Highness, this is the secret letter I captured in the battle. It contains the secret plan of Mei Fei and Hei Yu."

Li Yu unfolded the secret letter and read it carefully, his face becoming more solemn: "The plan of Concubine Mei and Hei Yu is indeed sinister and vicious. They actually tried to poison the emperor and use this to control the court!"

Liu Ruyan pondered for a moment and said, "Your Highness, we must take action immediately to stop their conspiracy."

Lian Di and Lian Fang also said: "We will fully cooperate with the prince to expose the conspiracy of Mei Fei and Hei Yu."

The situation in the palace is becoming increasingly tense, and a more intense contest is about to begin. Li Yu, Liu Ruyan, Leng Ying, Lian Di, Lian Fang and others work closely together to develop a detailed counterattack plan, ready to completely defeat the conspiracy of Mei Fei and Hei Yu.

As night fell, every corner of the palace was secretly stirring. Li Yu stood in front of the window, his eyes determined, and swore in his heart: "No matter what challenges I face, I will definitely protect this palace and my family."

In the early morning, the sun was shining brightly over the palace. A man dressed simply but with extraordinary temperament walked into the palace. He had delicate features and his eyes sparkled with wisdom. This man was the famous doctor in the world - Chu Tianji. His arrival attracted the attention of everyone in the palace.

When Leng Ying saw Chu Tianji, he hurried forward to greet him: "Mr. Chu, you are finally here."

Chu Tianji smiled slightly and nodded, "General Leng, I haven't seen you for many years. I hope you are well."

Leng Ying sighed, "Mr. Chu, the palace is in crisis, it's great that you can come to help."

Chu Tianji looked at Leng Ying with deep eyes: "I heard that the emperor was seriously ill, so I came to help. I hope I can detoxify the emperor and resolve the crisis."

When Crown Prince Li Yu heard that the genius doctor Chu Tianji had arrived, he immediately summoned everyone to discuss the matter.

Li Yu said to Chu Tianji: "Mr. Chu, the situation in the palace is very complicated. We need your help. Please find out the cause of my father's illness and save him."

Chu Tianji nodded: "Don't worry, Your Highness, I will do my best."

Crown Princess Liu Ruyan also said: "Mr. Chu's medical skills are superb. With him around, my father will definitely be safe."

Lian Di and Lian Fang looked at Chu Tianji nervously, hoping that he could bring a turn for the better.

When the Queen Mother heard Chu Tianji's arrival, a glimmer of hope rose in her heart. She immediately summoned Chu Tianji and told him to do his best to save the emperor.

The Queen Mother held Chu Tianji's hand and said excitedly: "Mr. Chu, the Emperor's life depends on you."

Chu Tianji said solemnly: "Don't worry, Queen Mother, I will do my best to find out the cause of the emperor's illness and relieve his pain."

When Concubine Mei heard Chu Tianji coming, she couldn't help but be secretly alert. She knew that if this miracle doctor found out the truth, her plan would fail.

Mei Fei summoned Lin Yixuan and Leng Tianji to discuss countermeasures: "Chu Tianji's medical skills are superb. Once he finds out the cause of the emperor's illness, our plan will be over."

Lin Yixuan pondered for a moment and said, "Your Majesty, we must stop Chu Tianji. As long as he can't heal the emperor, our plan still has hope."

Leng Tianji nodded: "I will arrange personnel to closely monitor Chu Tianji and take action if necessary."

Chu Tianji entered the emperor's bedroom and carefully examined the emperor's condition. He found that the emperor was indeed poisoned, but the poison was extremely hidden and difficult to detect.

Chu Tianji frowned slightly, pondered for a moment, and said to Li Yu: "Your Highness, the emperor's poisoning is extremely complicated and it will take time to detoxify."

Li Yu asked anxiously: "Mr. Chu, are you sure?"

Chu Tianji nodded: "Please rest assured, Your Highness, I will do my best to heal the emperor. But during this period, we need to strengthen our defense to prevent the enemy from causing trouble again."

Li Yu immediately summoned Leng Ying, Lian Di, Lian Fang and others to discuss defensive measures.

Leng Ying suggested: "Your Highness, we can strengthen the defense around the palace and send elite soldiers to patrol to prevent the enemy from taking advantage of the opportunity."

Lian Di and Lian Fang also agreed: "We will closely monitor the movements in the palace to ensure that Mr. Chu can safely treat the emperor."

Crown Prince Li Yu nodded: "Everyone has worked hard, we must protect the emperor and not let the enemy's conspiracy succeed."
