After returning from King of Liang, the couple were full of worries.

An Si put his arms around Ji Yu, pressed his temples, and asked softly, "Brother Yu, what is your Highness looking for you?"

Ji Yu didn't hide anything, and told about the elixir and the crown prince.

An Si was stunned: "Isn't this difficult for the strong?"

Ji Yu sighed lightly: "Yes! The medicine of immortality... This one is easier to handle."

He's not stupid, King of Liang doesn't want the emperor to be truly immortal.It's nothing more than wanting to please the emperor.

When the time comes, he will get some life-prolonging medicine and just perfunctory.

But regarding the matter of the crown prince... even the imperial doctor said that there is no cure, so what can he do?

"Fourth Brother." Ji Yu gently stroked An Si's frowning eyebrows: "What did Your Highness tell you?"

An Si put the hand he was holding to his lips and kissed, then sighed: "I hope our brother will stay in the capital to help him and the prince."

Ji Yu had expected this earlier, and was not surprised, and said again: "Your Highness also said, I hope we will restrain ourselves a bit in the future, and don't let people find out about our affairs, or about my stomach."

An Si sighed lightly: "Your Highness also told me about this."

Ji Yu shook his head and said, "Fourth brother, I'm afraid there will be bloody storms again in the future."

He could restrain himself with his fourth brother, but he couldn't hide his stomach after all.

Just now he didn't understand the meaning of King of Liang's words, but now he understands.

King of Liang meant that if the emperor asked him to refine the elixir of life, he would agree, but the emperor must die before the prince.

When the emperor died, the crown prince succeeded, and the status of King of Liang was stabilized, he didn't have to worry about his identity being exposed.

Is he about to be forced into a palace fight?

Early in the morning on the first day of the lunar new year, Mr. Ma shouted outside: "Master, it's time to wake up. Today is the Zhengdan Grand Court Meeting. The emperor calls for Mr. to attend."

As soon as An Si opened the door, Eunuch Ma walked in holding a large tray filled with clothes and jewelry.

Those clothes and jewelry were not only for An Si, but also for Ji Yu: "An Fulang, you have to dress up too, and get ready to go to the Eastern Palace."

The couple looked at each other and sighed secretly.

Then, each dressed up.

After recuperating for a day, An Si recovered well. Although there were still traces of the wind and frost in Baozhou on his face, the haggardness was gone.

Putting on the brocade robe prepared by Eunuch Ma and the jade crown, he was still as handsome as before.

No, more handsome.

After the baptism of war, An Si's killing and decisive temperament became even stronger, making his aura even more compelling.

Even more compelling than the crown prince and the ninth prince.

But An Si didn't like this kind of dressing up. After looking at the bronze mirror and seeing his appearance clearly, he took off the jade crown directly: "Mr. Ma, let's use the hairpin from before! The clothes have also been changed."

The hairpin was given to him by Brother Yu, and he liked it very much.

Eunuch Ma looked at the wooden hairpin on the dressing table and sighed secretly: "Yes."

As long as the son is willing to go to the Great Court Meeting, the wooden hairpin will be the wooden hairpin!

After changing the wooden hairpin and ordinary long gown, An Si carefully smeared black powder on Ji Yu's face.

Going back to the Eastern Palace this time, he doesn't need to dress up as a Taoist priest, but he has to dress up, especially to cover up the pregnancy mole on his forehead so that no one will find out his brother's identity.

But An Si felt that it wasn't enough to just cover up the mole, and she had to blacken her face.

He was worried that if Brother Yu went out like this, he would be coveted by others.

After all, Brother Yu's beauty is too outstanding.

After dressing up, he said distressedly: "Brother Yu, you must be careful."

Other people's husbands only need to stay at home and enjoy themselves.But his husband not only wants to make money, but also goes to the battlefield.It's all right now, and it's because of him that he has to get involved in the royal palace...

Ji Yu touched his face and said with a smile: "Don't worry, fourth brother, nothing will happen."

In the current situation, King of Liang would never let him have an accident.

Sure enough, when he got out of the small courtyard, he was not only accompanied by Eunuch Ma, but also guards such as Zeng Biaotou first guarded him layer by layer, and escorted him all the way to the Eastern Palace.

After entering the Eastern Palace, someone took them to the prince's bedroom.

However, only Ji Yu and Ma Gonggong can go in, Zeng Biaotou and the others are not allowed to enter.

Not only that, even Ji Yu's gun was taken away.

Ji Yu followed Ma Gonggong into the inner room, and saw the prince again.

In the past two days, the prince's face became more and more haggard, his eyes were closed and he remained motionless, as if he was about to die.

In the inner room besides the crown prince, there is also a nobleman in fine clothes, presumably the crown prince.

Sure enough, I heard Eunuch Ma salute and said: "This servant has seen the Crown Princess."

The crown princess covered her face with a veil, her eyes were swollen from crying: "Eunuch, come and see Your Highness."

Ji Yu stepped forward and saluted.

The princess looked at him blankly.

Although his complexion is dark, he is very young, at most seventeen or eighteen years old, how could he be a miracle doctor?

The princess suddenly got angry and said, "Mr. Ma, are you sure he can do it?"

Even the old imperial doctors in the Imperial Hospital were helpless, how dare a boy like him treat the crown prince?

Eunuch Ma cupped his hands and said: "Princess, don't worry, although he is young, he has excellent medical skills. If not, His Royal Highness King of Liang would not have invited him to see a doctor for the Crown Prince."

Upon hearing King of Liang, the princess put away the anger on her face and stopped talking.

Ji Yu didn't care about the Crown Princess' attitude either.

He is indeed not a doctor, and he is indeed young. It is only natural for the princess to question him.

Seeing that the concubine no longer obstructed him, Ji Yu walked to the bed, stared at the prince's face for a moment, the more he looked at it, the more he felt that his face was somewhat similar to that of old lady Lu.

Then he asked Ma Gonggong, "What are the symptoms of the prince?"

Eunuch Ma whispered: "The skin is red, the body is swollen, the gums are erosive, red and swollen, bad breath..."

Ji Yu asked again: "Does His Royal Highness like to eat sea fish?"

Eunuch Ma shook his head and said, "Our family has heard about Mrs. Lu's illness, but His Royal Highness is not. His Royal Highness never eats fish."

Don't eat fish?

Ji Yu pondered for a long time, and then said: "Can I hear His Highness the Crown Prince's tone?"

The princess was taken aback for a moment, and she was about to speak out her doubts, but seeing that Eunuch Ma didn't say anything, she had to swallow the words in her mouth.

Eunuch Ma cupped his hands to the prince and said, "Your Highness, this servant is rude."

Then, gently opened the prince's mouth.

Enduring the nausea, Ji Yu leaned over and smelled it. Amidst the rancid smell, he really smelled a metallic smell.

He had an idea in mind, looked up at Eunuch Ma, and asked, "Eunuch, can Your Highness take the elixir?"

Eunuch Ma still shook his head: "Not at all."

If you don't eat fish and don't take pills, you can only be poisoned.Ji Yu asked again: "How long has Your Highness been suffering from this disease?"

"About a month or so. At the beginning, it was just a headache, fatigue and insomnia. It has only become serious in the past few days."

"His Royal Highness, do you have any hobbies on weekdays?"

"Aside from playing the piano and drawing, I have no other hobbies."

Ji Yu could only say: "Crown Princess, can you take a look around in the palace?"

Although the Crown Princess didn't understand what he meant, she still nodded and said: "Yes."

Ji Yu didn't look far away either, and looked carefully on the bed with a candle in his hand.

After he checked all the quilts, pillows and mattresses, he still didn't find anything.I had to look around the bed.

But after searching around, he still found nothing, until he saw a faint circular mark on a low table next to the bed, and quickly asked, "What was placed here before?"

Eunuch Ma naturally didn't know, and turned to look at the princess.

The princess thought for a while before saying, "It's a pot of gladiolus, His Highness likes it very much."

Ji Yu stared at the circle and asked, "Then why aren't you posing now?"

The princess impatiently answered the question: "You see a doctor as soon as you see a doctor, why ask this?"

Ji Yu clasped his hands and said, "Small suspicion, Your Highness is poisoned."

"Poisoned?" Crown Princess Ma and Eunuch Ma were taken aback.

Eunuch Ma had an unbelievable expression on his face: "But our family has already checked, and it is not poisoning."

The princess quickly came back to her senses, and angrily said: "Bold! How could the prince be poisoned? I am responsible for the prince's diet. Are you suspicious of me?"

Ji Yu shook his head and said: "Back to the Crown Princess, Your Highness is not poisoned by food, but poisoned by other methods."

The Crown Princess breathed a sigh of relief, glanced at Eunuch Ma, and said, "How did you get poisoned?"

Ji Yu still shook his head: "I'll only know that if you look at the pot of gladiolus."

He said again: "It must be the gladiolus that was placed here before."

Eunuch Ma came to his senses: "Do you suspect that the gladiolus is poisonous?"

Keyou whispered: "But the gladiolus is not poisonous!"

Ji Yu shook his head again: "The gladiolus is naturally non-toxic, what I want to see is the pot and soil for the gladiolus."

Eunuch Ma finally understood what he meant, nodded and looked at the princess.

But the concubine twisted her veil, gritted her teeth and said, "It must be that bitch Yao Ji..."

Ji Yuma and his father-in-law patiently listened to her scolding for at least a quarter of an hour, only to see that she gradually calmed down and sent someone to find the pot of gladiolus.

Eunuch Ma went outside and glanced at a small servant waiting outside.

The waiter turned and left without saying a word.

After a cup of tea, the crown prince's person brought a pot of gladiolus.

Ji Yu used a drill to dig in the flower soil for a long time, but he didn't find anything unusual.

He asked the maid who delivered the flowers: "Is this flower placed in Your Highness's room before?"

The maid nodded and said, "Yes."

Ji Yu looked at Eunuch Ma, shook his head and said, "It must not be."

Eunuch Ma looked at the Crown Princess, who immediately changed her face and angrily scolded: "You dare to lie to me..."

But no matter how she reprimanded and scolded, the maid said that neither the flowers nor the soil had been changed.

Until a small waiter brought a cloth bag of soil, Ji Yu really turned out black beads of liquid that could roll and deform in it.

He pointed the droplet to Eunuch Ma: "Your Highness was killed by this poison."

Eunuch Ma asked puzzledly, "What is this?"

Ji Yu sighed lightly: "Mercury. It's mercury, and it's also cinnabar. This substance is volatile, and if people inhale it, they will be poisoned, and symptoms like His Highness will appear."

Ma Gonggong heard half-knowledge.

He knows that cinnabar can be used as medicine.

But never thought that it can also poison people?

However, now is not the time to think about these things: "Is there a way to detoxify?"
