After Zhao Ji learned about this, he was also secretly surprised.

Because Zhao Ji knew very well that the emperor's previous physical condition would not cause such a problem.

Moreover, the chief eunuch Su Xi knew the emperor so well that he also said that it was because the emperor took the elixir.

Then there is a high possibility that there is something wrong with this pill.

"The emperor has been so determined recently that I'm sure it won't be easy to persuade him to change his mind. Otherwise, you wouldn't have come to see me, eunuch."

Every word Zhao Ji spoke was sincere, and the eunuch Su Xi nodded helplessly.

The emperor now trusts Master Zhang very much. If you just say a few words, the emperor will definitely not listen.

Zhao Ji walked back and forth in the hall, wondering what to do.

"How about this, Eunuch Suxi, when the emperor takes the elixir, please scrape some powder off the elixir, and then secretly collect it for me."

Hearing Zhao Ji's order, the eunuch nodded. This was not a difficult task for Su Xi, who served the emperor personally every day.

"It's not a big deal. I just scrape it a little before the emperor uses it."

After sending the eunuch away, Zhao Ji frowned and thought for a moment. He still felt that this Master Zhang had many problems and he should work harder on him.

The Emperor has already taken the third of the twelve pills that Master Zhang sent some time ago.

At this rate, the emperor will probably have eaten all the pills in three months.

By then, no one could predict what would happen if the emperor continued to eat like this.

“We can’t let Master Zhang go like this anymore…” Zhao Ji frowned slightly.

So in the past two days, Zhao Ji ordered more people to carefully investigate the relationships behind Zhang Zhenren.

At the same time, the virtuous concubine in the harem suddenly fell ill.

You have to know that when the emperor is in good spirits, he spends the most time favoring Concubine Xian.

During this period, Concubine Xian was in great favor, so she immediately suspected that someone had poisoned her.

"Go and ask the chief of the Imperial Hospital to come over and show me what's going on!"

The virtuous concubine felt a terrible headache, as if there was a little man drilling in and out of her mind all the time.

Soon the head of the Imperial Medical Bureau arrived.

"Your Majesty's body is indeed poisoned, which is why you have a headache. I will help you check your diet and utensils."

After prescribing the detoxifying herbs, the head of the Imperial Medical Bureau began to check Concubine Jinxian's belongings.

But after checking, there was nothing wrong with the food and utensils around Concubine Xian.

"This is weird. We even checked the flowers, plants and trees, and there was nothing wrong with them. So how did I get poisoned? Could it be that someone else in the harem gave me something colorless and odorless that couldn't be detected?"

The virtuous concubine was very surprised.

The head of the Imperial Hospital was also puzzled: "Judging from the food and the Empress's utensils, there is no trace of poison, not even any trace of mutual generation and mutual restraint. This is enough to prove that the poison was not put on the food and utensils at all..."

The virtuous concubine was puzzled and the matter ended up being left unresolved.

However, this matter spread in the harem.

By the time the news reached Zhao Ji's ears, it had already become that Concubine Xian had angered God, so God deliberately poisoned her.

That's why even the imperial physician couldn't figure out who poisoned him.

"If there is no problem with the food and utensils, then it is very likely that the problem lies with the person in contact... During that period, Concubine Xian was very favored by the emperor, and could even be considered the only one favored..."

After a little thought, Zhao Ji felt that the problem still lay with the emperor.

As dusk approached, the Imperial Hospital welcomed an unexpected guest, who was none other than Zhao Ji.

That night, the windows of the Imperial Hospital were brightly lit, and no one knew what Zhao Ji talked about with the head of the hospital.

But after the morning court session the next day, the head of the Imperial Medical Bureau came to see the emperor and asked about his pulse.

Ever since the emperor took the pills and felt full of energy, he seldom asked the imperial physicians from the Imperial Medical Bureau to come over often.

Sometimes the emperor even refuses to check his pulse once a week.

However, this time when the head of the Imperial Medical Service came to check the emperor's pulse, Zhao Ji happened to be beside the emperor. After giving the emperor a few words of advice, the emperor stretched out his hand.

The head of the Imperial Hospital stretched out his hand to take the patient's pulse. The more he felt the pulse, the more solemn his expression became.

Seeing Zhao Ji right next to him, the head of the Imperial Hospital sighed deliberately.

Zhao Ji hurriedly asked, "Master, why do you look so solemn? Is the emperor not feeling well?"

The emperor frowned a little at this time.

The head of the Imperial Hospital spoke the truth: "The emperor's dragon body's Yang Fire is unstable. The most external manifestation is that the Yang Qi is strong, but in fact, it is a little weak inside..."

The emperor waved his hand impatiently: "Don't talk about that, just tell me what's going on."

The head of the Imperial Hospital knelt down and said, "Your Majesty seems to be in good health now, but I have checked his pulse and found that he is much weaker than the last time I checked his pulse. So overall, your Majesty is still in poor health. During this period, you should try to have less sex, avoid fatigue, and relax!"

When the emperor heard this, his face was filled with impatience.

"I know my own body very well. I can feel that I am in good health. You just want to trick me into taking those bitter medicines, which I don't like. Don't worry, the rewards for the Imperial Hospital will not be less. You should focus on the business!"

Obviously, the emperor thought that the head of the Imperial Medical Service was deliberately causing trouble.

Zhao Ji sighed slightly and said, "I think the head of the academy doesn't have the guts to lie in front of the emperor. I see that you seem to have something else to say. Is there anything else?"

The head of the Imperial Hospital knelt on the ground and said to the emperor: "After taking the pulse, I still have a question in my mind. I need your help to let my blood. Just a drop of blood from your fingertips will do!"

The emperor was already a little impatient and wanted to shake his head to refuse, but Zhao Ji said, "Your Majesty, for the sake of his great cause, he must still want to have more princes under the best circumstances. The head of the court has good intentions, so why don't you fulfill his wish for the sake of your future sons and grandsons!"

This time, I have accurately grasped the emperor's thoughts.

After all, there are so many princes now, but no one is capable of being an emperor, so I have long wanted to have a few more.

Zhao Ji used the excuse of being the crown prince, and his descendants would prosper the country for thousands of years, so the emperor was naturally more cautious.

"In that case, just do it."

The emperor gave a casual instruction and sat on the chair.

The head of the Imperial Hospital took out a silver needle, pricked the emperor's fingertip, and then squeezed out a drop of blood.

He then dripped the blood into a small bowl he carried with him.
