The emperor was also anxious. King Jing must not be in any danger. He ordered the guards to send King Jing back to the tent and summoned all the accompanying doctors to see King Jing.

King Jing suddenly vomited blood. Li Yu was more anxious than the emperor.

In his impression, vomiting blood was either a serious injury or a serious illness. King Jing was not injured. Was he sick?

Thanks to them being together all day, he didn't realize it at all. This princess was so incompetent!

Li Yu regretted and worried about King Jing. The guards came to send King Jing away. Li Yu jumped up and insisted on staying with him. King Jing vomited blood, but he was still very clear-headed. He lay in the sedan chair and held Li Yu's hand, asking Li Yu to rest assured.

In front of him, Li Yu would nod no matter what he said. But how could he be at peace in his heart? If King Jing fell, his world would also fall. What should he do?

Some people become unexpectedly calm when they are too anxious. Li Yu was like this at this moment.

He still had children. If King Jing was sick, he had to support the family. He couldn't just take care of himself and feel sad. He also had to think about the children and how to help King Jing.

After returning to the tent, Li Yu quickly wiped the moisture from his eyes and went to see the children first. The children were brought by Wang Xi and were very happy to see their father. Li Yu told them sadly that King Jing was sick and asked them not to make a fuss. Then he continued to entrust them to Wang Xi. Wang Xi was extremely anxious when he learned that King Jing was ill, but the princess was right, the young masters also needed care, and His Highness must not be worried during his illness. Wang Xi knelt down and earnestly begged Li Yu to take good care of King Jing. Li Yu agreed, and then stayed by King Jing's side, staring at him without blinking. The

imperial physicians came in waves, and asked Li Yu to rest several times, but Li Yu sat there and ignored them except asking about the condition.

"Tianchi, how do you feel?" Li Yu touched King Jing's cheek with a worried look.

King Jing smiled at him, there was nothing serious.

After vomiting blood, King Jing's complexion improved and his breathing became smoother.

Li Yu felt that King Jing did not lie to him, but the imperial physician repeatedly examined him many times, and for some reason, he never told him what the disease was.

The longer the consultation took, the more anxious Li Yu became. If the doctor didn't say anything, did it mean that the disease was very serious and even the doctor couldn't cure it, and he was not sure.

"Your Highness, I have a few more questions to ask you. Please tell me the truth." An old doctor, who was a bit older, came out to ask after discussing with other doctors.

Li Yu looked at King Jing inquiringly. If the doctor asked complicated questions, King Jing would have to write it down. I wonder if King Jing's body can handle it now?

King Jing actually didn't feel any discomfort. The doctor wanted to ask, and King Jing nodded in agreement. Li Yu immediately rushed to the table and grabbed a pen and paper.

The doctor said, "Before your highness vomited blood, did you feel any discomfort?"

King Jing picked up the pen and wrote: Qi and blood surged, chest stuffy and painful, throat burning like fire.

The doctor asked cautiously, "Your Highness, have you ever had a similar situation before?"

King Jing thought about it carefully, nodded, and wrote: Yes, but I didn't vomit blood.

The doctor asked, "Then your Highness, do you still remember when it was the first time?"

King Jing: "..."

King Jing wrote: More than a year ago.

It happened more than a year ago?

Li Yu's eyes suddenly turned red: "Why didn't you tell me?"

King Jing hurriedly wrote for him: You caught a cold and fell ill, I was in a hurry and felt unwell, and I got better immediately, and I didn't think much about it.

...Caught a cold?

Li Yu was in good health and had very few minor illnesses. He was stunned for a while before he reacted. This was the time when King Jing expressed his love to him earlier, and he didn't realize his own thoughts and had an awkward relationship with King Jing.

At that time, he only thought about his own unhappiness, how could he have thought that King Jing was sick and uncomfortable?

"I'm sorry, I didn't know..." Li Yu was so frustrated that he was about to cry.

King Jing shook his head quickly: It has nothing to do with you, I don't care.

King Jing was busy comforting Li Yu. After the old doctor got King Jing's answer, he was busy discussing with other doctors, and then carefully checked King Jing's pulse again.

The emperor should not have come to visit directly, but when he learned that the doctor had not reached a conclusion for a long time, the emperor could not sit still and came to King Jing's account in person.

"What happened to King Jing?" The emperor asked in a deep voice.

After experiencing so many things, the emperor had already chosen King Jing as the crown prince, and he didn't want anything to happen to King Jing.

The emperor asked in person, and the old doctor looked around and asked the emperor to send away the idle people first.

The emperor did as he was told. The old doctor then knelt down and said, "Your Majesty, according to our diagnosis, His Royal Highness Prince Jing was poisoned, and it has been a long time. Because of the critical situation just now, His Royal Highness's blood and qi surged, and he vomited some of the poisonous blood buried deep in his body, which was discovered only then."

Poisoned? ?

Prince Jing was shocked, and the emperor and Li Yu were also shocked. How could Prince Jing be poisoned? Could it be the Sixth Prince who did it?

Li Yu's heart was pulled up, and he didn't care that the emperor was there, so he rushed to ask, "Doctor, what kind of poison is it? Can it be cured? What do you mean by a long time?"

According to Prince Jing, could it be that he was poisoned a year ago?

Because of the poison, he... vomited black blood?

The emperor did not care about Li Yu's impoliteness and said to the doctor, "Answer me quickly. This is also the question I want to know."

The old doctor sorted out his thoughts and said respectfully, "Your Majesty, please allow me to answer the last question first. According to our diagnosis, the poison in your Highness's body has probably been lurking for decades. Until this year, the toxicity has subsided a little, and it was only because of the surge of qi and blood that it accidentally revealed clues."

"Decades?!" The emperor was shocked. Prince Jing was only in his twenties. How could he have been poisoned for decades?

Looking at Prince Jing's appearance, he was also very shocked. Even Prince Jing himself didn't know!

"You mean, could it be that Prince Jing was poisoned when he was young?"

The emperor recalled that Prince Jing was extremely weak when he was born. The imperial physician had treated him several times when he was very young. He got better only when he grew up. However, he did not show any signs of poisoning. Moreover, Prince Jing must have checked his pulse regularly. If he had been poisoned for a long time, why was it not discovered earlier?

The old imperial physician explained, "Your Majesty, this poison is not overbearing. Prince Jing does not have obvious discomfort on weekdays, and it is difficult to detect his pulse."

The emperor said, "Then is he in danger of his life if he is poisoned?"

The old imperial physician hesitated and shook his head, "I only know that your highness seems to be poisoned now, but what kind of poison is this? I have to look at the medical classics again and check your pulse to confirm it. However, this poison has been in your highness's body for a long time, so I don't think it will harm your life immediately."

The emperor was upset. He had just made up his mind to choose Prince Jing. Was God going to play such a big joke on him?

Prince Jing was born mute. His life was rough enough. He was the legitimate prince, but he was poisoned right under his nose without knowing it!

It took so long. It couldn't have been done by the Sixth Prince, who was a few years younger than Prince Jing. Who could it be? Who else wanted to harm Prince Jing?

The emperor was angry and felt guilty. He failed to take good care of Prince Jing, and he was even more sorry for Empress Xiaohui who was in the afterlife.

"No matter what, we must cure Prince Jing of this poison!" the emperor ordered.

The old doctor agreed.

The emperor turned around and thought of his four children. He asked anxiously, "Will this poison be passed on to the offspring?"

The old doctor said he couldn't be sure. The emperor ordered Wang Xi to bring the four children over. The old doctor examined the pulses of each of them and discussed with other doctors for a long time before he confirmed, "The young prince and the other three young princes were not poisoned."

The emperor finally got a good piece of news, which was a blessing in disguise.

The emperor summoned Wang Xi to ask questions. Wang Xi had always been with King Jing. If King Jing was poisoned when he was young, there would be something strange. Wang Xi couldn't have been unaware of it.

But Wang Xi recalled it again and again, and finally guaranteed with his life that he had never found any symptoms of poisoning in King Jing.

The doctor suddenly announced that King Jing was poisoned, and the poisoning time was decades ago. The emperor was already in a mess. Since Wang Xi said so, the emperor felt it was strange, but he had no other clues for the time being.

Li Yu listened to the emperor's questioning in a daze. It took him a long time to react. King Jing was poisoned when he was young?

But why didn't he know? This should not be a trivial matter. Why didn't the original book mention it at all?

I remember that King Jing was in good health until the end of the original book. Can we say that if King Jing hadn't vomited blood this time, they would not have discovered that King Jing was poisoned, and the poison would continue to lurk. So what is the use of this poison?

Generally, poisoning always has symptoms. King Jing... He does not look like he is poisoned at ordinary times. In the original book and in the world today, King Jing has no problems throughout his life, except...

Li Yu was originally serving ginseng soup to King Jing, and suddenly his hand trembled heavily. With a click, the silver spoon fell to the ground.

Li Yu leaned over to pick it up, but his hands were shaking so much that he could hardly pick it up.

Just now, he had a very scary idea.

King Jing was poisoned when he was young. This was only the speculation of the emperor and the imperial physician. However, it was strange that Wang Xi, who had been responsible for taking care of King Jing since he was young, had never noticed anything unusual about King Jing. Li Yu believed Wang Xi. Eunuch Wang had no need to lie at this time. Could it be that the poisoning was actually earlier, earlier than Wang Xi came to King Jing's side?

This poison was hidden so deeply that it was impossible to have no symptoms. Could it be that there were actually symptoms, but they were ignored by the world, so they could not be discovered?

This symptom was - King Jing's biggest flaw, muteness. Even if Li Yu was not an imperial physician, he knew that some poisons in the palace documents could cause deafness and muteness. What

if King Jing's muteness was not congenital, but caused by poison, is it possible?

Li Yu suddenly remembered a trivial matter a while ago.

In order to avoid passing on the muteness to his offspring, King Jing did not plan to have any more children. Li Yu was still determined to have a daughter, and he had inquired about the ancestors of the emperor and Empress Xiaohui, trying to calculate the probability. However, after asking, he found that no one on both sides had a muteness, which means that among hundreds of people in more than ten generations, only King Jing was mute.

From a genetic point of view, it is almost impossible.

But life is so complicated. Li Yu was young when he crossed into the book, and his understanding of genetics was also very superficial. He was even more worried whether this was a simple and crude setting in the original book.

Now that I think about it, many abrupt settings in the original book can be found in this world. For example, King Jing's name is very different from that of the princes. He is called Tianchi. In fact, this is because King Jing was originally called Tianjing, and later changed his name.

Could it be that there is a reason for the almost impossible but existing muteness? King Jing was drugged when he was very young, and then mistakenly thought to be born with the disease. Because of this, others never discovered that King Jing was poisoned?

Of course, this is also his guess. If it is true, it is too terrible. It would be best if there is evidence to overturn or confirm it.

King Jing was very young... so young that Wang Xi had not come yet... and was drugged...

A scene emerged in Li Yu's mind. The young King Jing was lying in the cradle, looking at his wet nurse, who swallowed a packet of medicine powder with tears in her eyes.

Shit, Li Yu was shocked by himself. Why did he suddenly think of this?

This is King Jing's secret, and he has never figured it out. Although the time matches and there is no Wang Xi, it was the wet nurse who took the medicine, not...

No!

Li Yu recalled that when chatting with Princess Jin Jue, she seemed to have mentioned that the wet nurse could pass the medicine to the child through the milk, so that the child could be cured.

So, if the wet nurse swallows poison, will the child suffer? ? ?

Li Yu: "..."

Li Yu felt that he had been thinking wildly, and he actually pressed it with horror!

Small fish? Seeing that he was in a daze, King Jing twirled his fingers.

Li Yu came to his senses and resisted the urge to tell King Jing.

Everything was his guess. He couldn't tell King Jing rashly. If it wasn't the case, the poisoning had nothing to do with the mute disease, wouldn't it mean that King Jing would be happy for nothing?

The top priority is to help the imperial doctor identify the poison first.

No matter what, I will save you.

Li Yu looked at King Jing and made a firm decision.
