The war of the Zhao court to quell the rebellion against the Nanban was fought for more than a year, and although it was finally won, it also cost a lot of national strength.

After the end of the battle, Zhao entered a stage of recuperation and began to recuperate in response to the constant provocations of the Northern Hu.

On the day of the return of the victorious army led by the King of Qin, he was summoned by Emperor Qinglong, praised by the courtiers, and his reputation among the people also reached a new height.

The prince of the East Palace and the second prince King Jin were envious and jealous, but they were helpless.

They are full of tricks in the matter of seizing the heir, and some of them are scheming, but leading the troops to fight is really not their strong point, and they can only watch the influence of King Qin on the army getting bigger and bigger.

The princes of the dynasties seized the succession, and without the support of the army, it was difficult to succeed.

King Qin repeatedly led his army to expeditions, and he was good at winning people's hearts, and many generals in the army became his supporters.

Among the three princes, King Qin was the only one who held military and political power at the same time.

There were some upright courtiers who made a statement to Emperor Qinglong, saying that the authority of King Qin was too heavy, and hoped that Emperor Qinglong would take back some of them, so as not to cause accidents in the future.

When Emperor Qinglong heard this, he just smiled faintly and didn't take it to heart.

He himself was at the peak of the Spring and Autumn Period, and firmly believed that he could sit on the throne for many more years, and most of the generals who were loyal to the King of Qin were under his control.

Therefore, he firmly believed that even if King Qin really had any different intentions, he would not be able to turn over his palm.

……

……

Emperor Qinglong, who had always been in good health, suddenly fell ill, and it is said that he was very sick.

After diagnosis and treatment, the imperial doctors of Tai Hospital did not figure out what kind of disease Emperor Qinglong was suffering from.

Although the news was blocked in the palace, there were still some powerful people who learned some inside information through various channels, and knew that Emperor Qinglong's symptoms were nausea and vomiting, diarrhea and abdominal pain, and even coma or convulsions in some cases......

Anyway, based on the news from all sides, they came to the conclusion that Emperor Qinglong's situation was very bad, and there was a possibility that he would kick his legs at any time.

After all, paper can't contain fire.

The news of Emperor Qinglong's serious illness was very loud and loud, and it didn't take long for it to spread from the court to the people, setting off huge waves.

The three princes and two princesses of Emperor Qinglong, as if they had made an appointment, entered the palace to visit Emperor Qinglong together, and it is said that they all looked sad when they came out.

This undoubtedly confirms that Emperor Qinglong's condition has reached a very serious point.

Zhao Ji, the crown prince of the East Palace, Zhao Yi, the king of Jin, and Zhao Bang, the king of Qin, after visiting Emperor Qinglong's return, gathered their confidants for several days, and they didn't know what was secretly discussing.

The people of the imperial capital city, who pay a little attention to the court, can feel that there is a low and depressing atmosphere in the sky above the imperial capital.

And the courtiers of Zhao State, under this low and depressing atmosphere, also felt a torrent of undercurrents.

This torrent is like a volcano underground, and at some point, it can erupt and stir the entire Zhao Kingdom.

Emperor Qinglong's illness was too strange, and several imperial doctors from the Tai Hospital suspected that someone had poisoned him, but after layers of strict investigation, this possibility was finally ruled out.

Although Yang Xu lives in the Yang manor outside the imperial capital, he also knows everything about the affairs in the imperial capital.

If it was placed in the past, he would stay away from Emperor Qinglong's serious illness, and he would be as far away as he could, and just watch from the sidelines.

But now it's different.

Today's Yang Xu has been labeled as the King of Qin, and has earned a lot of wealth for the King of Qin, and has been regarded as a thorn in the flesh and a thorn in the eye by the other two princes.

If Emperor Qinglong dies and the prince of the East Palace ascends the throne smoothly, then the end of King Qin will be very tragic, and Yang Xu will lose his life.

Zhao Yi, the king of Jin, seized the throne, and he couldn't live.

Therefore, if Yang Xu wants to save this life, there are only two possibilities:

The first is to restore the health of Emperor Qinglong, and the second is to assist the third prince Zhao Bang to ascend the throne.

It's just that these two things are easier said than done?

The emperor died and the prince of the East Palace inherited the unification, which was a justifiable thing.

However, the crown prince was not of good character and had a bad reputation among the courtiers, and many courtiers did not want to see the crown prince succeed to the throne.

Although the second prince is low-key and silent, but a dog that does not bark will bite, and he has been attracting all forces in the court for many years, secretly accumulating momentum, and cannot be underestimated in the competition for the throne.

And the king of Qin was supported by some courtiers and most of the military generals of the Zhao State, and he was the most powerful to win the throne.

What Yang Xu was most worried about was that once Emperor Qinglong died, the three princes would have an internal struggle for the throne, which would cause internal strife in Zhao and give several neighboring countries an opportunity to take advantage of.

In particular, the strength of the northern Hu country, which is comparable to the Zhao State, has millions of people in the country, and once the horse goes south, it will be a disaster for the people of the Zhao State.

In order to save the people of Zhao from the military disaster, Yang Xu felt that he should do something.

"Nausea, vomiting, diarrhea, abdominal pain, sometimes coma and convulsions...... This seems to be a symptom of lead poisoning......"

Yang Xu muttered to himself and began to search his intestines and stomach, thinking of ways to treat lead poisoning.

It's just that the medical level of this era is too poor, and he can't think of any good way to think about it.

In his head, he remembered some methods of dietary therapy to remove lead, but for Emperor Qinglong, who seemed to have a very serious lead poisoning, he didn't know if it could work. "Anyway, let's give it a try!"

Thinking of this, Yang Xu immediately rushed to King Qin's mansion, and after seeing King Qin, he analyzed the matter to King Qin in detail.

In Yang Xu's view, Emperor Qinglong, who had always been healthy, suddenly fell ill with lead poisoning, which was a very unusual thing, and it was very likely that someone deliberately did it and wanted to make a fool of the fire.

However, who did this, Yang Xu did not dare to draw conclusions.

It stands to reason that once Emperor Qinglong died, whoever benefited the most from it would be the most suspicious.

Qinglong died and the crown prince succeeded to the throne, which is a logical thing.

Therefore, the first object of Yang Xu's suspicion was the prince of the East Palace.

But when you think about it, what you can think of, others can also think of, and the prince will not be so stupid and do such an obvious thing.

But if this matter was not done by the prince of the East Palace, who would it be?

The second prince, Zhao Yi, the king of Jin, and Zhao Bang, the third prince, the king of Qin, are all objects of suspicion.

King Qin is accumulating strength right now, and it is on the rise, and it is not impossible to replace the crown prince in the future, so he should not do such a thing at the moment.

So calm down and think about it carefully, on the contrary, it is the second prince Zhao Yi who is the king of Jin is the most likely to start.

Anyway, in Yang Xu's opinion, Emperor Qinglong's illness is confusing, and who did it may become a mystery case.

"Lead poisoning? You mean, my father was not sick, but poisoned? ”

King Qin saw Yang Xu in the mansion, and after listening to Yang Xu's analysis, after being surprised, his brows furrowed tightly.

If a person can act again, there will always be omissions.

When Yang Xu was talking to King Qin, he carefully observed King Qin's expression, and saw that his surprised appearance was not like a disguise, and temporarily ruled out the possibility of him attacking.

"I've seen people with lead poisoning before, and the symptoms are very similar to those of His Majesty. However, at the moment, I am only guessing, not sure. By the way, what do the imperial doctors of the Tai Hospital say? ”

King Qin looked worried and sighed, "The imperial doctors have never seen this kind of disease, so they are all helpless. They prescribed medicine for nausea, vomiting, diarrhea, and abdominal pain to my father, but it didn't seem to work well. My father was now sometimes awake, sometimes unconscious, and looked in pain. ”

After a pause, he said: "The three of us, for various reasons, cannot always guard our father's side and fulfill our filial piety. So now the people who serve my father are mainly Duobao and Duofu. The two of them had not rested well for several days, and they had lost a lot of weight. ”

Yang Xu said: "Since the imperial doctor can't help it. Why don't you just try it the way I say, what if? ”

King Qin pondered for a moment and said, "I will ask people to tell Duobao and Duofu to do what you say." Yang Xu, if your father's health improves, you will have a great credit! ”
